From the Bloomberg Businessweek article on Sandy [same article as described in the previous post] comes this great talking point:
On Oct. 17 the giant German reinsurance company Munich Re issued a prescient report titled Severe Weather in North America. Globally, the rate of extreme weather events is rising, and “nowhere in the world is the rising number of natural catastrophes more evident than in North America.”
And this from the journal Climatic Change:
The answer to the oft-asked question of whether an event is caused by climate change is that it is the wrong question. All weather events are affected by climate change because the environment in which they occur is warmer and moister than it used to be. The air is warmer and moister and has led to a 5–10 % effect on precipitation and storms that is greatly amplified in extremes.
