Black Day in July for Greenland Ice Sheet

How hot is it this year?

Maybe the breaking of thousands of temperature records across the USA so far this year didn't get your attention.

Perhaps you have yet to be presented with the scary facts in Bill McKibben's latest article about Climate Change's New Math.

Well if you missed those cheery bits of reporting, have a gander at this shocking graph from meltfactor.org that shows a mind-blowing change in Greenland's ice sheet “albedo.” It has literally fallen off the chart in comparison to previous years.

Shrinking Arctic Ice May Cause Mercury Poisoning

Arctic ice cap shrinkage over 32 years

NASA has shown repeatedly that the Actic icecap is melting, and melting faster than climate models predict. This new visualization is stark and should be of obvious concern, simply because of the impact on sea levels. Now there is a potentially new threat. The process of shrinkage may cause a chemical reaction that could poison the Arctic ecosystem with mercury.

The disappearance of old, thick ice in the Arctic means an increase in bromine released into the atmosphere. The new, thinner ice has more salt and this is where the bromine comes from. As it melts it interacts with relatively benign gaseous mercury causing it to solidify and fall in a toxic form to the ground and into ocean water. The old old ice has less salt.

it is currently popular in denier circles to tout the April 2012 ice sheet extension as a sign of slowing of Arctic ice melt. This grasping at straws is not supported by the overall data, which shows Acrtic ice disappearance increasing. The April extent is mainly thinner, new ice that will easily melt, potentially causing the “bromine explosiion” described by NASA. The old, thicker icecap is shrinking more rapidly as time passes, and with it, the benign melting of salt-depleted ice.

Ethical Oil, the Sub-Prime Mortgage Scandal and The Next Great Generation

We are living in difficult times. The ongoing economic crisis started by the 2008 Sub-Prime Mortgage Scandal has all of us thinking about our future. We are vulnerable to unethical appeals to our anxiety in the form of quick fixes and easy profits. The promise of “Ethical Oil” is the worst of these appeals. We have to resist. Even more, we have to take decisive actions that the current leadership will not. To quote a famous man, we have an ordeal before us of the most grievous kind and we need a new generation of leadership to tackle it. We need the next Great Generation.

In 2008, world financial markets collapsed in dramatic fashion due to unethical investment practices, particularly in the previous five years. Toxic subprime mortgages had been injected like a virus into securities like Collateralized Debt Obligations (CDOs). Investment banks around the world were in on this scam and kept pushing it far beyond the point where it was obvious something had to give. Last year, the U.S. Financial Crisis Inquiry Commission concluded:

“the crisis was avoidable and was caused by: Widespread failures in financial regulation, including the Federal Reserve’s failure to stem the tide of toxic mortgages; Dramatic breakdowns in corporate governance including too many financial firms acting recklessly and taking on too much risk; An explosive mix of excessive borrowing and risk by households and Wall Street that put the financial system on a collision course with crisis; Key policy makers ill prepared for the crisis, lacking a full understanding of the financial system they oversaw; and systemic breaches in accountability and ethics at all levels.“
