I'd observed a couple of days before Sandy hit that climate change had disappeared from the campaign, but would surely be on the front burner when the rain stopped.
New York City Governor Andrew Cuomo and New York City Mayor Michael Bloomberg have weighed in.
And here is a dialogue among experts, and these paragraphs jumped out at me:
We have increased CO2 levels in the atmosphere by about 40% in the last 100 years (mostly the last 50 years) on the way to doubling later this century. The Earth has warmed up about 0.8°C (1.4°F) already due to the extra greenhouse gases we put in the atmosphere and it would have warmed even more if we weren’t also putting up smoke that reflects sunlight. This warming has increased Earth’s energy radiation to space, but the excess greenhouse gases are still trapping more heat than the Earth is radiating to space. This “energy imbalance” is about 0.6 watts/square meter. This doesn’t sound like much but it is equivalent to 400,000 Hiroshima atomic bombs going off every day (see my briefing for the math).Have at it with comments.
Extremely Hot Summers (“3-sigma” events) have increased 50X (5000%) in the past 50 years. There is 4% more water vapor in the atmosphere than 50 years ago. Average ocean temperatures have increased (90% of global warming energy goes into the ocean). The Arctic sea ice just reached its lowest level in thousands of years and in a few years you will be able to sail a boat to the North Pole for the first time in human history.
