Antarctic Ice Updates Available

I don’t tend to tell people I meet about my skeptical attitude toward global climate science as practiced by the UN.   When the subject does come up,  I usually have a rather unpleasant conversation.

All too often I get told about all the horrible things happening in Antarctica.  Yep Antarctica.   I then tell them Antarctica hasn’t been melting.   I tell them that most warming experienced in the last 200 years has been experienced on land in the Northern Hemisphere.   I am presumed to be less bright than I was at the start of the conversation.

I think Al Gore is probably to blame.  His 2005 film features lots of Antarctic boogie men.   I suppose I shouldn’t be surprised so many people believe Al’s propaganda.  Antarctica isn’t talked about much.  Al’s misinformation fills the void.  I just wish more people would at least listen to an opposing position.

My approach is about to change.  Reliable data is here and readily available.  I can point to a recognized expert.  One that has been in the forefront of Arctic melting, the National Snow and Ice Data Center.  This University of Colorado site has lots of neat stuff about the Arctic.  I’ve been following their Arctic Ice data for years.

And now they have Antarctic stuff too.   Yep, the world has been warming, the Arctic is melting, but the Antarctic Ice sheet is growing.    There are pictures…

And charts too…

Go Antarctica.   Antarctic Sea Ice has grown by about 10% in the last 30 years.  Not exactly what Al predicted in his film.

I know that the UN’s IPCC actually predicted Antarctic Ice could grow in their global warming models as area snowfall increased.   But they didn’t tell you it had been going on for years before they started their studies in the 1990’s. Who knows how long, this type of data has only been available since 1979.

Antarctica has not warmed yet, and the world has warmed.  The world is about a degree C warmer that it was about 200 years ago.   I wonder what Al Gore was thinking when he used only Antarctic Ice Core data as his proof of impending doom.

Individual ice cores are a poor proxy for the climate of the entire world because they provide information about a single location in a very cold place.   I see guessing.  It must be difficult to draw conclusions about North America or Europe or Asia from Antarctic data.   The ice core Al used in the film showed wild increases in carbon dioxide and no real 20th century warming, (which Al failed to point out in his film) which is typical of Antarctic Ice Cores.  Here’s a typical one

Notice how temperature went down 130,00 years ago while carbon dioxide remained stable.  The current temperature stability (the last 10,000 years) appears to be happening while carbon dioxide is skyrocketing.

It’ll be nice to have a respected source (National Snow and Ice Data Center)  to point global warming fear mongers to. Antarctic Ice melting really isn’t the immediate problem too many ill informed citizens believe it to be.

Global climate change is a very difficult science problem.   Doubt is a reasonable response.  I’d be the first to admit I don’t know what the answer is.  Too many advocates of IPCC positions insist they know the answer.   Come on guys.  You are guessing.

Maybe this Antarctic data will help spread a bit of doubt.  And doubt is a good thing.

  1. Looks like you have more disdain to Al Gore than the topic that you are arguing about.

    • You are correct. Al Gore is one of those people who thinks he knows what the answer is. I’m of the opinion that the topic is too complicated for anyone to be so confident. I find that kind of arrogance misplaced in science. I’d be OK with that, but he also thinks people that disagree with him are unethical, immoral and/or stupid. His film tried to equate skeptics to the smoking lobby and he also used his dead sister to emphasize the point. I was personally insulted by that action.

      When I remind myself that he is only a politician doing what politicians do, I feel better. But it is safe to say I am not an Al Gore fan.

      • I may have been too quick to agree with Rodel. I dislike Al, but the issues surrounding global climate change are more important to me than Mr. Gore. Science with an agenda scares me…and global warming science has been agenda driven since day one.
