Animation of Arctic Sea Ice Minimum Volume 1979-2012

If your roof is leaking, do you ignore it and hope it will fix itself? 

This new animation created by Andy Lee Robinson depicts Arctic Sea Ice minimum volumes reached every September since 1979. It's a depressing sight, for sure. Andy makes it a little less difficult to view with his own piano sountrack, a composition called “Ice Dreams”:

Arctic Melts As New Greenpeace Report Warns Of Coal Expansion In Australia

SOME processes of cause and effect are relatively easy to get your head around.

For example, if I smash the end of my thumb with a hammer then the effect will be extreme sharp pain, followed by a short burst of f****** swearing and then probably one of those under-the-nail bruises that stick around for months.

An equally simple process to understand is that burning fossil fuels like oil, coal and gas releases extra carbon dioxide into the atmosphere, which causes temperatures to rise. The extra CO2 sticks around for a century or so, perhaps longer.

Now this is of course a hugely oversimplified version of the greenhouse effect. There's lots of “noise” in the climate system, but the fundamentals are there. This brings us to the Arctic. No honestly, it really does.

Earlier this week, the US Government's National Snow and Ice Data Center declared that more sea ice melted away this year than at any other time since records began in 1979.

The Arctic Sea Ice is Melting - no matter how bad George Will doesn't want it to

There remains a lot of messaging and spin running rampant online over Washington Post colmunist George Will’s misguided and baseless claims that sea ice coverage is similar to 1979.

DeSmog writer Mitchell Anderson has been covering this baffling story for us and doing a great job, but I wanted to provide a few of the sources that have done a particularly good job at highlighting just how much sea ice we have lost since the 1970’s when we first started recording such things. 

These source easily and compellingly explain away George Will’s incorrect claim that sea ice coverage is the same today as it was in 1979.


1. You can watch the extent of Arctic Ice melt decreasing over time. Here’s a great satellite image time series video done by NASA that shows the year-to-year melting of sea ice in the Arctic. I don’t know how anyone could argue that sea ice in the Arctic is the same as it was in 1979 after watching this video:

Poznan: Fiddling while Rome burns

As Canadian delegates to the UN Framework Convention on Climate Change conference in Poznan, Poland struggle to prevent any progress toward a international agreement to replace the Kyoto Protocol, Canadian scientist David Barber announces that climate change is coming faster and more furiously than even the most pessimistic modellers could have imagined.

Barber, speaking at the International Arctic Change 2008 conference this week in Quebec City, said sea ice in the Canadian Arctic, which the Intergovernmental Panel on Climate Change said could melt as early as 2100, is now in danger of melting in 2015, nearly a century ahead of schedule.

New on the Endangered Species List: Perennial Arctic Ice

The North Pole could be free of sea ice for the first time in recorded history this summer, according to National Geographic News.

And that would have the effect of speeding global warming, as highly reflective ice gives way to heat absorbing water in the high Arctic.

As NatGeo reports, scientists were shocked last year when the high Arctic lost 65 per cent of its ice cover in one year, an unprecedented loss over a time scale they previously thought was impossible. And, perversely, that generates more of the Deniers' favorite commodity: doubt.

We can all now doubt that things were as bad as we might have feared. As it turns out: they're worse.
