Forget it Rush

Dangerous, Potentially-Irreversible Climate Change Happening Faster Than Scientists Thought:

A lot's happened with climate change science since the last IPCC report. With the general consensus (hacked CRU email non-revelation brouhaha aside) being that things are happening much faster than we expected and that the uncertainty regarding human causes being over whether it 90% certainty or 99% certainty more than anything else. With the COP15 conference just two weeks away a group of UK scientists has taken the time to distill the current state of climate change for us. The picture is clear and stark:
First of all, the scientific evidence for "dangerous, long-term and potentially irreversible climate change has strengthened significantly" since the last IPCC report two years ago:

CO2 concentrations continue to rise and after a decade of stability, methane concentrations (more potent, though shorter lived than CO2...) have begun increasing again.

The years 2000-2009 have been warmer on average than any other decade in the past 150 years.

Precipitation changes have been at the upper limits of what climate models predicted, characterized by decreases in the subtropics and increases in high latitudes.

Arctic summer sea ice cover declined suddenly in 2007 and 2008, melting 40% more than the average prediction from the IPCC report.

Evidence for continued and accelerating sea-level rise increases around the world -- by 2100 we're on track for double the amount of sea level rise projected back in 2007 -- that's more than a meter, with continued rises seen in subsequent centuries.
Rush, Sean and Alex Jones are making a huge deal about the "leaked" emails and how global warming is all a hoax to promote a One World Order. Wonder what they'll make of this?
