And the release of methane is going to throw CO2 off to the side.

Earlier this year, Canada's insurance industry reported that 2013 was the costliest ever because of claims from extreme weather, with losses rising above $3 billion

It's almost as if 2013 had the most expensive stuff, the most stuff and the most people ever in Canadian history.

"Glaciers in Yukon have lost about 22% since the 1950s,"

Just a quick question, when was the first few years those Glaciers were losing mass? Could it be that they have been shrinking before the kick up in CO2 prior to the 1900s? If that was so wouldn't it indicate a factor other than CO2 driven shrinking?

Everyone panic and demand higher taxes to solve this crisis!!

Most people don't think that CC/AGW is entirely people's fault- but the use of coal and then oil to power civilization has probably sped up the process.

In my mind, the only question is how much change are people are responsible for? 1%? 2% 5%? 10%? 25%?

Well if you take a climate model and strip out everything but CO2 warming you get a max projection at current CO2 emissions of 1.5C in 100 years. The biggest warming caused by CO2 has already happened. So humans are likely on the hook for 0.5C of warming so far.

I wouldn't have thought it as high as 33% (.5 C / 1.5 C), but it's certainly possible.
