A Three Question Climate Change Knowledge Test

Climate change is a scientific discussion that has been hijacked by political considerations.  Many people have strong opinions about climate change and too many of those opinions are based on political rather than scientific reality.   Politics are here, there and everywhere.  And the UN, a strangely political place, is the recognized world expert.  Need I say more.

With that in mind I have developed a simple 3 question test.  If you already know all the answers, congratulations!

Question 1. —  What is Climate Sensitivity and how does it impact the global climate debate?

Most people have never heard of Climate Sensitivity.  Some will be well aware of the idea, but not know the name.  Others are simply unaware of the arguments.  A general knowledge of how climate sensitivity is used by the global warming doom crowd is important.

Carbon dioxide is a weak greenhouse gas.  Water vapor and methane are strong greenhouse gases.   As carbon dioxide changes in the atmosphere, it is predicted to make changes in other climate variables.   IF the model assumes a high climate sensitivity to carbon dioxide then small changes in carbon dioxide cause big changes in climate.  Low sensitivity produces much less change.   Many UN modelers assume a fairly high carbon dioxide sensitivity.  This high sensitivity leads to “tipping points” and gloom and doom.

Climate models are run by computers. These computers use carbon dioxide as a key input variable.  They then predict temperature years and centuries into the future.   UN approved climate models do not agree with each other.   Models can vary by as much as 5 degrees C by the year 2100.

As time goes by computers get faster, more information becomes available and the models are adjusted.  Predictions made just 10 years ago have proven to be wildly high.  Either the climate sensitivity was too high or … they have failed to properly consider natural climate variation.

Question 2. — What is natural climate variation?

If you don’t get this one right, you’re really not paying attention to the science.

We live in an ice age time.  We have been in an ice age for the last 2.5 million years.  For the last 11,000 years we have been in the Holocene, an oddly steady period of climate history.  Climate during the Holocene has been warm and stable.  Ice cores go back about 700,000 years.  The Holocene is the only climate period during that time that has stayed warm for 11,000 years.   The norm is colder.  Much colder.

Here is a copy of a Vostok Antarctic Ice Corps showing climate variations at the drill site.

This chart starts in the present time and then goes back 400,000 years.  Another widely used chart displays the last 50,000 years of the chart beginning at the oldest with the newest dates at the right:

It’s easy to see the Holocene.  20,000 years ago New York City was covered in ice…and 130,000 years the world was warmer than it is right now.   This wildly changing climate is called natural climate variation.

Now lets look at the last 10,000 years using a Greenland Ice Core:

This chart ends with year 2009.  Man has only been able to influence climate for perhaps 200 years.  Any variations seen before the beginning of the Industrial Revolution (the blue on the chart) must, by definition, be something that man did not cause.  Three times in the last 10,000 years it has been more than a degree warmer than it is right now.

What change is natural and what is man caused?  This is one very difficult science problem.

Question 3 — How is electricity stored?

This is a bit of a trick question.  Generally, electricity is not stored.   Power generation is an on demand business.  You turn on the light switch, the utility provides the electricity and the lights go on.  The utility grid has a bit of excess capacity running all the time so that it can maintain a stable grid.

A small amount of electricity is stored in batteries, but batteries are expensive and have manufacturing and disposal problems.  Batteries are not now a viable option.  People are working hard to solve this problem.   But in science, wishing doesn’t make it so.  When the solution is found…we can consider it, but for right now we have to look at what is available today, not what might be there in 10 or 20 years.

Electricity is not stored, any electricity provided must be immediately used by the grid.  Electrical demand varies throughout the day and the electric utility has to vary production to meet that demand.  Demand usually peaks just before sunrise and again in the early evening.  Wind and solar are only available when mother nature feels like it.  Germany, the largest solar power market in the world is so far North that solar provides almost no power in the winter.   Munich, which is in Southern Germany, has the same latitude as International Falls, Minnesota.

The Energy Information Administration (EIA) releases statistics every month on power generation in the USA.  Here is the data for a 12 month rolling average including October 2015.

Coal   Natural Gas    Nuclear    Hydro     Solar     Renewable (inc. wind)

35%         32%              19%           6%           0.6%                          7%

Natural gas burns much cleaner than coal but does create some carbon dioxide when burned.  Hydro and Nuclear are clean (from a carbon dioxide perspective)   All four are unpopular with environmentalists for various reasons and they represent about 92% of all power production.

Wind is the most difficult to predict alternative fuel, and it’s the least reliable.   Places with lots of wind relative to other sources of power have odd things happen from time to time.  When the wind really blows, Germany gets so much power from wind that they have to pay neighboring countries to take the energy.  A US utility made news a few months ago when it gave away electricity during peak wind production.  A  cheap reliable battery network would fix this problem.  Unfortunately none exists right now.

Whenever I encounter a global warming true believer I ask them the same simple question.   What is your opinion on Nuclear Power?  Coal represents 35% of total load now and most environmentalists want that at zero.   Where is that capacity going to come from?   There is only one currently available source that can bridge the gap to a better world with wind, solar and cheap batteries and that choice is Nuclear.

Which of course begs the question.   What do you fear more, Nuclear Power or global warming?  I myself am skeptical about the science that touts global disaster, but they could be right.  On the chance that they might be at least partly right…. I support more Nuclear Energy.  How about You?

Note to the IPCC — Develop Realistic Goals

The IPCC has a global temperature goal for the World that makes no sense.   The leading “authority” on climate wants to keep the world temperature to less than 2 degrees C higher than it was at the beginning of the Industrial Revolution.  The Earth has already warmed over a degree C since 1750. This makes the IPCC limit  something less a than 1 degree C from current temperatures.

Natural climate variation makes the goal unattainable in the long run.  At some time in the future, the world will change (probably begin cooling) in  a way the IPCC failed to anticipate.   Nobody can make such a precise temperature guarantee.  Our knowledge of the science is simply too primitive.  And yet the goal is repeated over and over again.  I see references to the goal almost daily.  A goal that is nothing more than a wild ass guess.

We live in an ice age cycle and have been in this cycle for some 2.5 million years.   Average Antarctic temperatures as calculated using ice cores during the last three ice age cycles (about 400,000 years) have varied by about 13 degrees C.  Average Antarctic temperatures have been 8 degrees colder than today, and the coldest place on earth averaged 5 degrees C warmer some 130,000 years ago.  Most of the time it’s colder.

We are living in the Holocene, a 10,000 year period of very stable temperatures.   When one looks at the Vostok Ice Core from Antarctica it is clear that the Holocene is a surprisingly stable time from a temperature perspective.  Nowhere else on the chart does the climate stay stable and warm for 10,000 years.

Now let’s take a peek at a Greenland Ice Core that only goes back about 10,000 years.  This core takes place entirely within the Holocene and covers most of the period.

https://wattsupwiththat.files.wordpress.com/2013/03/gisp2-ice-core-temperatures.jpg?w=740&h=555

This ice core indicates that we have spent most of the last thousand years in a relatively cool period of the Holocene.   The recent warming has brought us up to the average.  The average temperature for the last 10,000 years in this particular part of Greenland was about the same as it is right now.  The chart stoped some 95 years ago and back then the world was about .7 degrees colder than it is today.   Add that bit back in and were about average for the Holocene.

The world has warmed rapidly, but there are lots of periods along the chart that are more severe.  Yep…wild natural climate variation…in a calm period of the ice age cycle.  Hmmm…..

I’m not a big fan of ice cores because they provide climate for a single location and regional climate varies more wildly than the world as a whole.   But if Greenland has varied by more than 3 degrees C at a time when the entire planet was unusually stable and warm, maybe a 1 degree C goal is for the world includes just a bit of wishful thinking.

Remembering that the world has warmed steadily since the end of the Little Ice Age, let’s look again at recent temperature data provided by East Anglia University in the UK.

gtc graph

Wild annual variation everywhere.  My favorite section…from 1863 to 1878, the world warmed by a bit over half a degree  C in only 15 years.  Warming before 1950 is presumed by the IPCC to be mostly natural variation.  Furthermore, the world warmed by almost .7 degree C between 1912 and 1942, a 30 year period not unlike the period between 1976 and 1998.  Since 1998, the pattern has been unusually stable.  More stable than at any time in the last 175 years.  No single year has varied from the prior year by more than .2 degree C during the last 17 years

One would never guess we are living (since 1998) in a time of relatively stable temperatures.    Reports in the media cast climate change as an accelerating problem.   And they could be right.  Perhaps natural climate variation is masking a disaster in the making?

But the IPCC could be wrong too.  The IPCC has been making temperature predictions since 1992.  The world went along as predicted until 1998, and then it didn’t.  7 years of right, 18 years of wrong.  7 for 25, not bad if your playing baseball.  I expect more from my scientists. When I look at IPCC data, I see guessing.  Wild Ass Guessing.

Problems are here, there, everywhere in the climate game.  Guessing is a part of the scientific process.  And guessing is everywhere as scientists attempt to predict future climate.  Carbon dioxide is higher than it has been in a really long time, and man probably plays a significant part in that impact.  But it is not the only input required in any attempt to predict future climate based on the past.

We have difficulty accurately measuring the Earth’s temperature both right now and in the past.  Arguments persist about volcanic impacts.  Sudden changes in the Earth’s magnetic field might matter.  Some think solar winds are important. The World was dramatically changed when Antarctica and South America became separate continents some 23 million years ago.

We know solar output varies and some suspect sunspot activity might matter.   Ice ages are presumed to be impacted by the location of the continents and by variations in the Earth’s orbit.   Land near the poles makes the world colder than when most land is near the equator is it was 50 million years ago.  The shape of the the earth’s orbit varies, as does it’s tilt.  And the earth wobbles too.  All 3 orbital variations are presumed to impact climate.

I suspect the IPCC is simply playing politics.  They need the problem to be immediate and urgent in order to secure funding.   And they know that our society lacks the political will to do what they say needs to be done.  If something bad happens, they can say I told you so.  If nothing happens they can blame natural climate variation.   And as long as the problem persists in the minds of the population, they continue to get funding!

The IPCC cannot afford to tell you the truth. It might impact funding.

THIS TRUTH —   The  scientific community is confident that man is impacting climate.  That impact is extraordinarily difficult to quantify,  measure,  or predict   When scientists use computer models they are guessing.  The models are not as precise as they should be and change wildly as new information come to life.   There is much we still do not know. The entire process is strongly influenced by  politics and economics . We all share the planet together.  We have a shared responsibility to be good stewards of the environment.  Society should act in a cautious manner because it might be important.

Gloom and doom sells newspapers and provides funding, but does little to advance the science.  I wish those that advocate climate change science in it’s current form were just a bit more circumspect and a bit less confident they are right.   Until I see some healthy skepticism from within the advocate community, I will remain skeptical.

USA isn’t Number 1 in Carbon Emissions

This morning I decided to look up some recent carbon dioxide production statistics.  I performed a Google search and selected the Natural Resources Defense Council website, which came up first on the search (and you wondered how Google made money).  The site was chock full of climate propaganda and half truths.  I selected the following question from their website:

Q:  What country is the largest source of global warming pollution?

A:  The United States. Though Americans make up just 4 percent of the world’s population, we produce 25 percent of the carbon dioxide pollution from fossil-fuel burning — by far the largest share of any country. In fact, the United States emits more carbon dioxide than China, India and Japan, combined. Clearly America ought to take a leadership role in solving the problem. And as the world’s top developer of new technologies, we are well positioned to do so — we already have the know-how.

Al Gore used similar data in his 2006 film, An Inconvenient Truth. 

Both Al and the Environmental lobby are wrong.  Big Surprise!  They must be using ancient data.  The data used by Mr. Gore  in his 2006 released film has a 1999 copyright date.  Data takes time to compile.  I’d guess the actual data was probably produced using data form the mid 1990’s.   2014 data is now available .

I wish the Natural Resource Defense Council had spent a bit more on content  editing and a bit less on online advertising.

The Statistica website has  data from 2014.  Their data shows the USA is second place with 14.7% of total manmade carbon dioxide production.  China leads and has led the country chart since 2006.  Their 2014 share was 23.4%, a number that has been steadily rising for over 20 years.  India, another rapid grower sits in third position with 5.7%, followed by Russia (4.9%), Brazil (4.7.%), Japan(3.6%), Indonesia (2.31%), Germany (2.23%) and Korea (1.71%).

Why did Al Gore use old statistics in 2006 when he made his film and why does the USA’s largest environmental lobby still use 20 year old data today?   Because it works as a fundraising tool.  Potential givers want  to feel important. China (and India too) have the ability to overwhelm the mathematics.  Why give.  We in the USA are powerless to impact the autocracy that is China.

I’d argue the data doesn’t begin to tell the full story.   Population density, location and GDP all must also be considered.  China and the USA are about the same size, but China has 4 times as many people and produces less than 50% of the goods the USA produces.  All those people with middle class desires.  Urbanization will lead to additional carbon production.  Throw in GDP differences and China looks more and more like the Elephant in the room nobody talks about

China is a bit closer to the equator than the USA, which means they need to use less energy to keep warm.   The USA has been reducing  their carbon footprint steadily since about 2000.  China continues to grow theirs at nearly 8% per year.

India is another rapid grower and that has the potential to be a perplexing problem for the climate control crowd.   India is about 1/3 the size of the USA and produces a bit more than 1/3 of the USA’s total carbon dioxide.   Their population is still growing rapidly which means that their carbon production will grow rapidly unless they can use much less on a per capita basis.   Their current per capita use is rising from a very low level which means that India has a long runway of increased carbon production in front of them.

China’s impact is huge.  India’s is growing rapidly.  The USA’s potential climate impact (if you trust the UN scientists) has been declining for most of the 21st century.  Who knows what will happen next.  Any notion that we in the USA can change the world with rather modest  changes at home seems a bit fanciful.

Perhaps the guys at the UN are wrong.  Their temperature predictions for the first 15 years of the 21st century have been awful.  The world has been colder than predicted.  Yes surface data shows 2014 as being a warm year.  Satellite data disagrees; and both land based and satellite data are lower than UN predictions made just a few years ago.  Perhaps increased carbon dioxide won’t be as damaging as advertised.

China’s growth rate is slowing and they are building a bunch of new Nuclear Power Plants which should slow their emissions growth rate in the 2020’s.   Maybe the elephant in the room will move more carefully a few years from now.

Time will tell.

New Climate Science Rule — No Anecdotal “Proof” allowed

Mr. Obama gave a speech at the UN yesterday.   I didn’t see the speech, but I did read the Washington Post article covering it.  We heard that climate was

  • changing faster than our ability to address it
  • The alarm bells are ringing, we cannot pretend we do not hear them
  • the once distant threat of climate change has now moved firmly into the present.

The article went on to say that Mr Obama:

ticked of a list of recent U.S. weather disasters – from Hurricane Sandy to the drought in the West – as evidence that the once-distant threat of climate change has “now moved firmly into the present.”

I felt like I was in a 2006 time warp, watching An Inconvenient Truth, and listening to Al Gore talk.  The approach and the key talking points were virtually indistinguishable.   So many mistakes.  Mistakes Al Gore made in 2006, and Mr. Obama repeated some 8 years later.

  • The change in climate is not accelerating.   The opposite is happening.  The world warmed rapidly in the 1990’s and peaked in 1998.  Since then the world has had virtually no change in world temperatures.   Carbon levels are higher, but climate has not changed.  The 2014 UN Climate Assessment blames the dampening of the Ocean’s and insists that the warmth will come some day.   Right now the world is not warming.
  • Hurricane Sandy was a relatively routine storm as far as Hurricanes go.   Atlantic hurricanes have become less frequent in recent years.  Florida has not had a hurricane hit its shores in 9 years, a record.  2013 set records for low activity and 2014 has continued the trend.   This does not mean they won’t accelerate in the future, but it does mean that, so far at least, Atlantic hurricanes have not increased in intensity or frequency because of climate change.
  • Multiple recent studies show that the drought in the West is consistent with the historical weather pattern of the region.   Last month I visited Mesa Verde National Park.   The Indians that lived in Southwest Colorado for close to 1000 years, moved away some 800 years ago after 24 years of drought.

The world is a big place.  Anecdotal evidence can be found to support any climate argument you want to make.  Ice in the Arctic is melting more rapidly than in the recent past, but at the same time Antarctic Ice is growing at record rates.  Both are short term localized events that prove absolutely nothing.

Sure it’s warmer than it was and man is probably partially responsible.  But the climate changes wildly all by itself.   It’s really difficult to distinguish between natural climate variation and man caused events and so far at least, UN computer models have been inconsistent in their predictions.

1709 was a really cold year in Europe.  Really cold.  And the world was warmer than it is today some 10,000 years ago.  Both were part of the world climate changing without the assistance of man.   Anecdotal evidence doesn’t really prove anything.   Let’s stop pretending it does.

Yes carbon is accelerating and it would be better, probably, if it weren’t.  And we should try to do more to impact our planet less.  But are we really sure that Mr. Obama was correct when he said:

There’s one issue that will define the contours of this century more dramatically than any other; and that is the urgent and growing threat of a changing climate.

Maybe, maybe not?   My favorites are destruction of the Oceans and over population.  If we could get  people in the poor countries of Asia and Africa to procreate less, I’d like our chances better.     Let’s meet in 86 years and see who’s right.

Polar Bears, Whales, Climate Science and Exxon

Wow!

What  a day. Four different articles in Section One of the Anchorage Daily News worthy of a post.  Most days nothing catches my eye.  Not today….well it is April Fools Day.

  1. UN Court orders Japan to halt Antarctic whaling was the feature page 1 story of the day.   The court voted 12 to 4 against the Japanese claim that killing up to 1000 whales a year was a form of scientific research.
  2. Researchers use DNA to trace lineage of polar bears was also a page one story.  A University of Alaska Fairbanks study used DNA evidence to demonstrate that the Polar Bear, Black Bear and Brown Bear have specific genetic histories.   The article went on to discuss the Endangered Species Act and the use of computer models to try to place the Polar Bear on the Endangered Species List.
  3. Exxon: Climate Change Policy Highly Unlikely to Limit Fossil Fuel Sales appeared on Page 3.   This article featured arguments between Exxon scientists and Environmental scientists about the relative costs and benefits of fossil fuels to society.  Surprise…they disagree.
  4. UN report: Global warming dials up our risks made it’s appearance on page 5.  The UN released a 32-volume report on climate on Monday.   This AP article discussed the impact climate change will have on food production.  The article talked about the impacts on poor people and the impacts on fine wine and coffee too.

There you have it, four wonderful April Fools Day treats in the first five pages of  my local paper.

Article 1 – Whaling in Antarctica

Apparently, last year the UN’s highest court had a trail.  In that trial, the Japanese government claimed that killing up to 1000 whales a year in the Antarctic was being done as a form of scientific research.

The Japanese position fails the laugh test.  When a legal position is so bad that others witnessing the lawsuit might actually laugh during the argument, that position has failed the laugh test.  Trust me, no lawyer wants to present a position that fails the laugh test.  Japan just failed.

This story says  something about Japan and about the UN too. 4 judges agreed with the Japanese position?!  And it took the court months and months to come to this conclusion?  World politics is a constant source of amazement.

Article 2 – Polar Bears

When I first started reading about Polar Bears, the conventional wisdom was that they became a distinct species about 200,000 years ago.   Perhaps two years ago, early DNA studies changed that to 600,000 and then another study last year said it could be as high is 4 million years.   This study pegs the change at 1.2 million years plus or minus.  And the study acknowledges that the time clock being used is approximate.

The lead scientist, Dr. Matthew Cronin, has been a vocal critic of the Endangered Species Act.   He has made, according to the article,  the following statements about the listing of the Polar Bear as an endangered species

It seems logical that if polar bears survived previous warm, ice free periods, the could survive another.

and

This is of course speculation, but so is predicting they will not survive, as the proponents of the Endangered Species Act listing of polar bears have done.

and

I don’t think you should base endangered species on predictions and models.  It should be focused on real-world problems.

All this was music to my ears. No so for Dr Steven C. Amstrup, principal author of the report recommending the ESA listing.  He called Dr Cronin’s study incautious and misleading.  Dr. Amstrup then pointed out that the current warming cycle was happening much more rapidly than had previous cycles.

Wrong.  The world is predicted by IPCC climate scientists to begin rapid warming soon. The World has been warming for over 200 years, but most of that has been natural climate variation.  The 2007 IPCC Climate Synopses predicted immediate warming.  The world was supposed to be about .2 degree C warmer than it is right now and that warming was supposed to accelerate with time.  The IPCC was wrong.

Warming to date is well within the normal range of the last 10,000 years.  The Earth warmed at a relatively rapid rate between 1993 and 1998, which also included a climate changing volcanic eruption and a strong El Nino.  Warming stopped and has been relatively stable since 1998 as this Satellite Temperature chart demonstrates:

https://i1.wp.com/www.drroyspencer.com/wp-content/uploads/UAH_LT_1979_thru_February_2014_v5.png

Perhaps Dr. Amstrup is just a tiny bit defensive.   He based all his arguments on climate models that have …at least so far…been wrong.

Article 3 Exxon vs Environmentalists

This article seemed perfect to me for April 1st.   Exxon and the Environmental lobby differ on the relative value of fossil fuels.   Duh!  Talk about a firm grasp on the obvious.   The article can be summed up by a single paragraph about halfway through the article.

Exxon and the environmental groups agree that climate change is a risk and that society will take steps to reduce emissions from fossil fuels to slow the buildup of greenhouse gases in the atmosphere.  They differ, however, on how drastic society’s response could be, and what would cost more — severely restricting fossil fuel consumption or not doing so and allowing more carbon dioxide to build up in the atmosphere.

Exxon thinks emissions will peak in about 2030.  The peak level of emissions will be less a risk than the environmental lobby predicts.    I have no idea where the truth lies.  Vested interests are everywhere.   The article really broke no new ground and provided no new information.

Article 4 — UN Report on Climate

Our local paper ran an AP story titled UN Report: Global warming dials up our risks in today’s paper.  I cannot find the article at AP or at adn.com (The Anchorage Daily News website).  I found stories with the same title.   I also found a story with the same title written by the same AP writer, but the story was completely different.  The Anchorage Daily News has a history of editing AP articles, so I read the online AP article.   The two articles are completely different. I have never encountered this before.

It does feel a bit like an April Fools Day prank…on page 5 of the Anchorage Daily News.

My local newspaper version of the AP story is an awful story.  It focuses solely on food supply issues caused by global climate change.   I wish I could find a way to link it.   The article mixes starvation in India with fine wine and coffee in the developed world.  Global climate change will change food availability and costs according to the article.  And not in a good way.

The article talked about potential starvation in India.     Yep, as India goes from a country with a billion people to a country with 1.5 billion people, food is going to become more of an issue.   Perhaps birth control or lack thereof might be a part of India’s food supply problem.   Maybe even more important than carbon dioxide levels in the atmosphere?

 

 

Dr. Hansen’s Dream World – Part 3

This post is the third of 3 dealing with an article published on December 3rd by Dr. Hansen and 17 other scientists.  The article’s basic argument is that carbon dioxide is creating an energy imbalance.   They attempt to measure the energy imbalance, and make predictions about the future.

The article is refreshing in that it finally addresses many of my objections about the IPCC.  It actually discusses other possible drivers for climate change and tries to provide a compelling argument for why these other drivers of climate are not important.   I am less confident than I was before reading the article, but I still have doubts, many doubts.

Dr. Hansen made up his mind about the importance of carbon dioxide before most of the research used was performed.   He has been an advocate for a really long time.   And many of his arguments use data with very short histories.   The data displayed about the sun only goes back 40 years.

https://i1.wp.com/www.plosone.org/article/fetchObject.action

I want to see what happened during the last cooling cycle from 1940 to 1976.   Information that went back to the beginning of the Little Ice Age would be even better.

The Energy Imbalance discussion uses data from buoys.  The changing amount of energy stored by the oceans is used as an indicator that the world is accumulating energy.  That it is out of balance.  Virtually all of the data used in the calculation is less than 10 years old.   It is more a snapshot in time rather than a trend established over a long period of time.

And I worry about the data set.   There are about 4,000 buoys spread out around the globe.  They drift with the currents and too many are near land.  Many of the buoys have only been available since 2005.   The data is so new and so important to his conclusions that I suspect lots of wild guessing.

The article also dismisses all the short term temperature predictions in past IPCC reports.  It uses the oceans and the large ice masses near the poles as reasons why the horrible changes predicted have been late.   This effectively eliminates one of my main complaints about the IPCC….stupid short term predictions.

And they bravely encourage widespread use of Nuclear Power.   I think Nuclear power is a necessary part of any green answer.  Unfortunately with the exception of China, the world is walking away from nukes.

The article paints a bleak picture of the world unless we make the following changes to the way we generate energy.

  1. The article advocated carbon trading on a worldwide scale.
  2. They advocated widespread use of wind and solar.
  3. They advocated widespread use of Nuclear to replace both coal and natural gas generation.

Carbon trading requires all the countries of the world to agree.   That is unlikely to happen.  Without a worldwide agreement, carbon trading only works for the countries that don’t join.   Today, China and the USA have a huge trading advantage when trading with the EU because they don’t have to worry about carbon taxes.

Wind and solar will continue to be developed, but they have limitations due to Mother Nature.  If and when a better battery is developed,  their use can expand.  Until then, their use will be limited.

Germany has so much solar that their power grid is developing reliability issues when solar is not available.    Germany’s ability to manufacture goods may be impacted.   Germany’s 21st century solution, a brand new coal fired power plant!

The world has changed a lot since 2006 when Al Gore won a Nobel Prize for his political commercial masquerading as a documentary film.   Dr. Hansen and his cohorts barely got any press for their latest bit of gloom and doom.  The world has passed them by.  Why?

They have been gloomy for a long time. Doom failed to arrive on schedule.   Throw in climate-gate and the Mann Hockey Stick debate; the group has lost some credibility.  How did they get into this position?

I think it starts with their mind set.  Dr. James Hansen and his comrades live in a political dream world.  Why do I say they live in a dream world?  Let me count the ways:

  1. They think the science is so compelling that there is no other plausible view.  When Dr. Hansen and 17 other scientists wrote the article I am critiquing, they declared there were no competing interests.  The world does not have unlimited funds.  Every dollar spent on global warming is not spent on something else.  Things like world overpopulation, starvation in Africa,  AIDS, Cancer, over fishing the oceans, and safe drinking water all have the potential to be competing interests.
  2. This group lives on government funds.  Every other need of the government is a competing interest.
  3. Competing interests go beyond government money.  Jobs are at stake in the coal industry.   Wind turbines kill birds, including some endangered species.  People dislike the appearance of wind mills in pristine areas.   Solar panels take up lots of space and must be imported, impacting trade.   Nuclear, well it’s Nuclear, need we say more.
  4. The carbon dioxide is evil climate group has made many mistakes.  These mistakes have given the skeptical community reason to doubt their results.  They have been caught cooking data (Climate-gate), adopting questionable scientific theories (The Mann Hockey Stick Graph) and their short term predictions have been wrong.  Horribly wrong.
  5. They have been too secretive and too vague.  They have argued against sharing data with skeptics.  If the data is good, they should be doing exactly the opposite.  In 2005, the Scientific American  wrote an article defending this use of secrecy shortly after the Mann Hockey Stick data began to be attacked by skeptics.   The Scientific American defended Dr. Mann aggressively.  Interestingly, Dr. Hansen in his new article, appears to argue that the specific temperature conclusions in the Mann Hockey Stick Graph were wrong.
  6. The politics has turned against them.  A worldwide recession, cheaper and more plentiful fossil fuels, and the Fukashima Nuclear Disaster have changed the political landscape.   Global warming advocates are failing because people fear Nuclear Power.  Germany and Japan are abandoning their Nukes, only China seems willing to build new Nuclear plants.
  7. Long ago they made one very large mistake, they let a politician become point man for the cause, Al Gore.   Mr. Gore is driven by political realities.  He will never advocate Nuclear Power.   Green energy without Nuclear energy does not work.  It will not work until a cheap way to store electrical energy is developed.    The green community has been advocating a solution that does not work.  This is now becoming obvious.
  8. They expect the United Nations to be an effective force.   This expectation never made sense.   Much is made of the original Kyoto Treaty.   A treaty that did not work.  Carbon emissions soared during it’s implementation period. Kyoto created too many winners and losers.   Russia got special treatment.  India and China got a free ride.   It was politically unacceptable in the USA.
  9. China has become significant politically.   Any solution must involve China.  In a few years  China will produce a third of the world’s anthropogenic carbon dioxide. The 2009 Copenhagen attempt at a new treaty failed in large part because there was no way for the world community to get China to do what they felt needed to be done.  Absent political concessions in China, the USA will never come on board.   The two largest economies in the world must be a part of any real agreement.
  10. Stop living in the past.   Dr. Hansen has been an advocate of counting all the pollution a country has produced since the beginning of the Industrial Revolution when dictating what each country is obligated to do to stop warming.   I personally don’t buy the argument scientifically, but that’s beside the point.  This approach has effectively given China a pass.  It provides them with an excuse not to cooperate.
  11. Global warming hawks need to learn how to compromise.   Natural gas is a cleaner burning fuel than coal.  While it is not as good as Nuclear as a base load fuel, from a carbon dioxide perspective, it is much better than coal.   No new plants are currently under construction.   Decades will pas before any new Nuclear plants come on line in the USA. And old plants are being retired as we speak. Dr. Hansen and his cohorts should be adopting natural gas as a lesser of two evils while they wait for technology to provide a better choice in the short run.

I would be more convinced by the arguments in Dr. Hansen’s article if Dr. Hansen hadn’t made his mind up about global climate change in the 1980’s.   15 years ago doom was coming and coming soon.   His article still says it’s coming, but it could be delayed by centuries.   It is a better argument than the immediate gloom arguments of 15 years ago. Unfortunately for him, politicians usually don’t respond to problems in the indefinite future.

And still  I wonder.   Is Dr. Hansen right now….or is he just selectively looking at data to defend a position he has held for 30 years?   Only time will tell….lots of time.

Dr. Hansen’s Dream World — part 2

It’s time to beat up on Dr. Hansen some more.  My last post only dealt with the introduction of  a new article published by Dr. Hansen and 17 other authors“Dangerous Climate Change”: Required Reduction of Carbon Emissions to Protect Young People, Future Generations and Nature is the less than catchy title. This post deals with the first section of the body of the article, the section that deals with temperature.

Oh! First a sidebar…NASA (Dr. Hansen’s employer) Climate Research Funding  and Columbia University funding helped pay for the project.   I don’t mind NASA funding research, but I’d rather have them not use their own employees….it feels like we (the people of the United States) are paying them twice.

In part 1 of this discussion I mentioned that Dr. Hansen had been somewhat cavalier with his data selection.   I accused him of using regional data, and of cherry picking data.  But Dr. Hansen does so much more.  He uses old data, he misrepresents data and uses his own work as a resource.

He does all that within the first major section of the article, which is called Global Temperature and Earth’s Energy Balance.   In a subsection titled Temperature, he begins by showing temperature graphs.  The following graphs are displayed:

https://i1.wp.com/www.plosone.org/article/fetchObject.action

I find those charts difficult to read and I think they misrepresent the recent past.  Here are three other charts that better tell the story.   First is the East Anglia University chart that was prepared in 2010:

https://i2.wp.com/www.climatechangefacts.info/ClimateChangeImages/cru_gtc.gif

The total amount of temperature variation shown is less on the East Anglia chart than on the charts provided in the article.  A lot less.  Dr. Hansen has a rationale for using only average data, but I don’t like the choice.  The 13 year average data masks all recent data and makes details much more difficult to interpret.   It in effect spreads the El Nino data out for a long period of time.

I like the older (pre 2013) East Anglia charts.  The University changed something in 2013 that made 1998 look cooler relative to the rest of the chart.  I suspect data fudging and prefer the older charts.

Next is a 45 year chart I used in my last post.  It shows East Anglia data, and  2 satellite sets of data:

https://i0.wp.com/upload.wikimedia.org/wikipedia/commons/thumb/7/7e/Satellite_Temperatures.png/800px-Satellite_Temperatures.png

and finally the current UAH chart:

https://i0.wp.com/www.drroyspencer.com/wp-content/uploads/UAH_LT_1979_thru_November_2013_v5.6.png

I like the UAH data best.  It is the most current and the most detailed.   I am fascinated by the changes in data from month to month.  The data Dr.Hansen chose makes it look like there is a steady march upward with a small pause at the end of the chart; the other charts tell a different, less ominous sounding story.

In the text that appears with the graphs, Dr. Hansen tells his story complete with multiple cites, including one to an article by an expert.   Yep, he cites himself.  He does that on 3 different occasions within the first two sub-section of the article.

A little further into the piece we get this statement:

The Greenland and Antarctic ice sheets began to shed ice at a rate, now several hundred cubic kilometers per year, which is continuing to accelerate.

An article by Edward. Hanna et al. is cited as the source material for the statement.   The article was published in Nature in June of 2013 and the article has this to say about Antarctica:

It remains unclear whether East Antarctica has been gaining or losing ice mass over the past 20 years, and uncertainties in ice-mass change for West Antarctica and the Antarctic Peninsula remain large.

Parts of Antarctica are losing ice, other parts are not.  And there is lots of uncertainty. Surface ice adjacent to Antarctica is at record high levels according to the National Snow and Ice Data Center.

I am sure that if the world warms, ice will melt.  If enough melts it could become a serious problem. But Dr. Hansen overreached in this area.

The next sentence of the report (after the Greenland stuff) is as follows:

Mountain glaciers are receding rapidly all around the world  with effects on seasonal freshwater availability of major river.

Dr. Hansen provided two cite references for the Mountain glacier section.  Both were published in 2007.  That’s really old data in this field.  Recent studies blame some of the melting  not on carbon dioxide, but on particulate matter.   Air pollution turns the snow a slightly grey color, which causes it to melt faster.  It’s still a man caused problem, but the solution to the problem is to clean the air, not to eliminate carbon dioxide.

Oh…carbon black impacts melting in Greenland and the Arctic too.

The first of two cites supporting his argument for rapid melting referenced an article about the Andes; a part of the world that has not experienced significant warming.  The second site was the 2007 IPCC  Climate Change Report.   I was surprised to see this cite.  This part of the IPCC report is famous…or should I say infamous.  The Guardian ran a story on it in 2010.   The Guardian reported the following:

The UN’s climate science body has admitted that a claim made in its 2007 report – that Himalayan glaciers could melt away by 2035 – was unfounded.

The admission today followed a New Scientist article last week that revealed the source of the claim made in the 2007 report by the Intergovernmental Panel on Climate Change (IPCC) was not peer-reviewed scientific literature – but a media interview with a scientist conducted in 1999. Several senior scientists have now said the claim was unrealistic and that the large Himalayan glaciers could not melt in a few decades.

In a statement, the IPCC said the paragraph “refers to poorly substantiated estimates of rate of recession and date for the disappearance of Himalayan glaciers. In drafting the paragraph in question, the clear and well-established standards of evidence, required by the IPCC procedures, were not applied properly.”

So, in 2010, the IPCC admitted the cite referenced by Dr. Hansen was flawed.  And his other cite was both regional and at an odd location.

The IPCC makes several statements  in their 2007 Synopses report.  Two are applicable here.  1) Warming has been regional  with most warming occurring over land in the Northern Hemisphere and 2) climate on a less than continental scale is subject to wild swings which makes it difficult to predict.

In finishing up the temperature section of the paper,  the article discusses the changes seen in the world. We are told the following:

Mega-heatwaves, such as those in Europe in 2003, the Moscow area in 2010, Texas and Oklahoma in 2011, Greenland in 2012, and Australia in 2013 have become more widespread with the increase demonstrably linked to global warming

The world is a big place.  I can make any argument I want to by picking my location.  If I want to sound alarmist about tropical storms, I can discuss the disastrous impacts of the Typhoon that destroyed so much of the Philippines.  If I want to sound calming, I can discuss the record low number of hurricanes  in the Atlantic during the same period.

Both events happened.  Both are regional.  And both happened in a part of the world that has not warmed significantly in the last 30 years.

The article provides two cites for the statement saying these items are demonstrably linked to global warming.  One cite provides a statistical argument for extreme weather whenever there is any warming or cooling.  It is in effect an argument that says extremes will appear whenever the average weather changes.   Climate has not been changing recently, so Dr. Hansen’s conclusion seems to be unsupported by the cite. The second site deals with one event, the 2013 drought in Australia.  No link was provided to that reference.

In Part 3, I’ll look at Dr. Hansen’s evaluations as to why climate politics has stalled and what needs to be done.  Stay tuned.
