A Tour of the Cryosphere 2009

I first saw this on Net-Cool which is a great site to subscribe to for finding really interesting things on the web.

This movie explains some of the reasons of concern for monitoring the increase in temperatures that we have felt since the 1960s.  It is very well done and enjoyable to watch.  Unlike An Inconvenient Truth, it admits that this is not pure imagery but some CGI has been done.

If you can handle the bandwidth, you will see better graphics here rather than watching the embedded YouTube video below.

Climatologist slams RealClimate.org for ‘erroneously communicating the reality of the how climate system is actually behaving’ – Rebuts Myths On Sea Level, Oceans and Arctic Ice

I have talked about RealClimate.org many times in the past. In general, the gentlemen over there are pretty smart but they do tend to be one-sided in their analysis. They consistently take the side of “global warming is caused by humans” and they don’t treat others with much respect.

I started questioning their partisanship when they lashed out at the UK judge that said that “An Inconvenient Truth” was not 100% factual. They didn’t like me calling them out on that.  They then spiked some of my comments on their site when degraded scientific discussion to a challenge of who has a bigger wallet.

Scientists find bigger than expected polar ice melt

There is no question that our climate has changed slightly compared to 20 years ago.  Most of the data points to increases of temperature and the most significant (and obvious if you are in the Arctic) is the diminished amount of ice in the Arctic Ocean.  While there is some question as to the cause of this melting (see my ocean currents article), there is little question that it is occurring.

This article discusses some of the observations that scientists have seen regarding the ice melt and some possible repercussions.  The article is somewhat refreshing though in that it focuses on what can be observed rather than focusing on what might be causing the warming.  Since it was so evenly reported, I felt it was of significant interest to my readers.

NASA satellite searching for global warming clues crashes near Antarctica

It looks like we are going to have to wait for awhile now for better data on what is really going on with our atmosphere and climate.  The satellite that NASA sent up to study the flow of carbon dioxide developed technical difficulties and crashed.

Once again, we see that our ability to travel outside of our world is still quite experimental and we struggle to do it with the repeatability of plane flights.  If I was a conspiracy fearing individual (which I am not) I would question if scientists deliberately sabotaged the flight so that real data that could prove or disprove climate models could not be gathered.  Such speculation is obviously foolish though.

Al Gore’s statements for the Senate

These statements are part of the public record so I am comfortable that I do not harm any copyrights by reproducing them in entirety here.  Please note that these are the prepared statements of former Vice President Al Gore.

If you don’t want to read such serious stuff, I suggest you read “Canceled Due to Global Warming” and have a good chuckle.

Statement to the Senate Foreign Relations Committee As Prepared Hon. Al Gore Wednesday, January 28, 2009

We are here today to talk about how we as Americans and how the
United States of America as part of the global community should address
the dangerous and growing threat of the climate crisis.

Scientists flip-flop on Antarctic melting

I originally found this opinion in “The Detroit News” and so you can click through and read the entire article.  I really cannot explain this topic better than Mr. Taylor and I suggest that you read my highlights here and then read the full article if it is interesting to you.

Understand that Mr. Taylor works for the Heartland Institute which is known as being pretty close to the edge when it comes to rational discussion on this issue.  However, even people with extremely strong feelings on an issue are not totally wrong and need to be listened to. 

Ice melting across globe at accelerating rate, NASA says

CNN – December 16, 2008

This story about the rapid melting of ice in the major cold areas of the world (Greenland, Antarctica, and Alaska) needs to cause everyone concern. While the story doesn’t convincingly discuss the causality of the situation, it does point out that increased melting accelerates the planets warming due to loss of reflectivity of the “white” ice.

The article goes on to point out the increase of pine beetles which is theorized to be attributed to a warmer environment. It even goes so far as to predict the increase in sea level (ala Al Gore) by the end of the century based on this loss of ice.

Antarctic ice shelf ‘hanging by thread’: European scientists

Breitbart.com – July 10, 2008

image This is quite concerning. Most of the instability in the ice shelves in Antarctica have been during the summer.  Now it appears that this shelf is in danger even though the continent is currently undergoing winter.  There have been a rash of shelves collapsing and Nobel Prize winner, Al Gore, spoke of this in his film “An Inconvenient Truth”. It is not conclusive why ice shelves collapse but it is important for us to explore these situations.

It appears that this shelf is being “eroded” underneath by warm waters.  This is likely the cause of the rapid failure of the other shelves as well.  Interestingly, some of the other shelves exhibited water pooling on the surface before their collapse but there is no mention of this situation in this article.

Antarctic ice threatened by ozone-hole recovery

Nature – April 29, 2008

Once again, we see an example of how the climate models that are predicting the end of the world, as we know it, have not taken into account some important factors.  Granted, this particular article is discussing another model (or at least calculation and prediction). It still points out that our models are far from complete and we need to spend more money and effort to increase this capability.

Recovery of the ozone hole above Antarctica could warm the Antarctic and cause more ice to melt in coming decades, researchers say. As the ozone hole heals, wind patterns that shield the interior of the polar region from warm air may break down, causing warming in the Antarctica as well as warmer and drier conditions in Australia.

Antarctica, Is It Really In Danger?

GUEST ARTICLE:

By Julee Mitchelsin

With all of the fervor these days about the dangers of global warming many people are concerned about the fate of Antarctica. The fears are that the ice that makes up the continent is melting faster than normal and not freezing back as it usually does with a very even ebb and flow. The concerns are that this will eventually raise the sea level enough to put major cities and land masses under water and leave millions of people homeless and/or even dead.
