Global environmental challenges
For years, climate scientists were circumspect when asked if a specific bit of violent weather — for example, Hurricane Irene, the late-summer storm that slammed the heavily populated U.S. East Coast — could be blamed in some way on climate change.
“Climate is what you expect,” the scientists would say, “while weather is what you get.” They would often go on to say that while increasingly severe weather and correspondingly serious costs and consequences were forecast in climate change computer simulations, there was no way to directly blame a given storm on human-generated heat-trapping gases in Earth’s atmosphere.
There still is no direct line between a certain amount of warming and a certain storm, wildfire, drought or flood. But there is a “new normal,” detailed by scientists on a new website . Staffed and advised by some of the most well-known climate change experts in the United States and elsewhere, the site says plainly that what the computer models foretold in 2007 is clearly documented to be occurring.
“All weather events are now influenced by climate change because all weather now develops in a different environment than before,” the Climate Communication site noted in an article released days after Irene dumped record amounts of rain on the U.S. Mid-Atlantic and Northeast.
At issue is the decision by American Electric Power to put its plans for carbon capture and storage on hold, due to the weak economy and the lack of a U.S. plan to limit emissions of climate-warming carbon dioxide. Read the Reuters story about it here.
