Arctic Meltdown : A Very Big Deal

Found at : Green Man

It continues to astonish me that environmental reporters cannot pick up the Arctic meltdown ball and run with it.

The trend in meltdown in the northernmost latitudes is a very big deal – and it’s ongoing, it hasn’t stopped, gone into remission or gone away.

The nature of the ice is changing – so much so that scientific monitoring equipment was confused.

It is now clear that Arctic summer sea ice is in a “death spiral”, a phrase first used very recently, in an attempt to properly describe what is happening :-

Cold Focus : Disturbing Trends

After several key projects to alert the general public to the melting of the Arctic, some have concluded that pictures of unusual calving icebergs, sea ice scans and time lapse series of glacier disappearance are not enough, not sufficient, to make the case.

Sea Ice Not In Recovery

Watch it while it all melts away…this isn’t modelling, it’s data :-

Early Bud Catches Warm

If you’re reading this in the Southern Hemisphere, you will probably already know that the temperatures have been somewhat heated since the beginning of this year.

If you’re reading this in the Northern Hemisphere, and I know most of you are, because I’ve checked, you will probably not have the faintest idea that local cold does not mean global cold.

What’s been happening, to use colloquial, ordinary, everyday language, is that the Climate has been changing at the top of the world, the region near the North Pole. Winds have changed, patterns of heating and freezing have changed, rain and snowfall have changed.

This has had a knock-on effect – some of the areas further South have had a great deal of cooling over Winter. The Arctic has been acting like a giant air conditioner for parts of Northern Europe and Northern America.

You shiver in Paris (or London, or New York), but the Siberian and Canadian permafrost is melting.

Arctic Meltdown : Methane Eruptions

Video Credit : The Guardian

[ PLEASE NOTE : The animation is dated 6th April 2009, so the text in the sub-titles means the year 2008 when it says “last year”. ]

European Winter 2009-2010 is turning out to be a bit parky – best not to go outside unless you can help it (or you’re under the age of 10 and love snowball fights).

However, wintry as it may be in Europe, the Arctic region is experiencing slush-inducing temperatures, and once-frozen sub-sea permafrost is starting to warm up, rot and give off methane. Lots of it :-

Arctic Meltdown : Sooner Than We Think

The Pliocene, the era in Earth History formerly known as the Pleiocene, is being treated as a potential “analogue” for our Globally Warmed world.

Several strands of Climate Change Science research have been undertaken in recent months, and they are all coming up with dismal results.

The United States Geological Survey (USGS) is the latest to unleash data on us :-

http://www.usgs.gov/newsroom/article.asp?ID=2372&from=rss_home

“Arctic Could Face Warmer and Ice-Free Conditions : There is increased evidence that the Arctic could face seasonally ice-free conditions and much warmer temperatures in the future. Scientists documented evidence that the Arctic Ocean and Nordic Seas were too warm to support summer sea ice during the mid-Pliocene warm period (3.3 to 3 million years ago). This period is characterized by warm temperatures similar to those projected for the end of this century, and is used as an analog to understand future conditions…“In looking back 3 million years, we see a very different pattern of heat distribution than today with much warmer waters in the high latitudes,” said USGS scientist Marci Robinson. “The lack of summer sea ice during the mid-Pliocene suggests that the record-setting melting of Arctic sea ice over the past few years could be an early warning of more significant changes to come.”…”

Feeling strangely perturbed ? That would be your internal paradigms spinning.

Gore Was Mostly Right

Al Gore speak at the December 2009 Climate Talks in Copenhagen this week, and you would not believe how he got mauled by the Media and the Denier-Sceptics. Watch and listen to the links below and consider if you can detect the part that stuck in the throat of those who resist putting a halt to Global Warming.

Breaking Up : Bad News from Gas and Ice

It’s proving to be a bad year for Greenhouse Gas control and Polar Ice integrity.

Despite the drop in production of the Developed Economies, due to the downturn/recession, Carbon Dioxide (CO2) levels in the atmosphere carried on rising :-
