A recent study led by James Hansen of the NASA Goddard Institute for Space Studies confirms that, because of carbon dioxide emissions and other greenhouse gases, Earth is trapping more energy from the sun than it is releasing back into space.
The U.N. International Panel on Climate Change (IPCC) estimates that global temperatures will rise 2 to 10 degrees by 2100. A "middle of the road" projection is for an average 5-degree increase by the end of the century, says Caspar Amman of the National Center for Atmospheric Research in Boulder, Colo.
What the various factions don't necessarily agree on is what to do about it. The heart of the discussion is "really about how to deal with climate change, not whether it's happening," says energy technology expert James Dooley of the Battelle Joint Global Change Research Institute in College Park, Md. "What are my company's options for reducing greenhouse gas emissions? Are there new business opportunities associated with addressing climate change? Those are the questions many businesses are asking today."
General Electric Chairman Jeffrey Immelt recently announced that his company, which reports $135 billion in annual revenue, will spend $1.5 billion a year to research conservation, pollution and the emission of greenhouse gases. Joining him for the announcement were executives from such mainline corporations as American Electric Power, Boeing and Cinergy.
To be sure, many companies — most notably oil industry leader ExxonMobil — still express skepticism about the effects of global warming. And the Bush administration has supported research and voluntary initiatives but has pulled back from a multi-nation pact on environmental constraints.
Power companies want to know what sort of carbon constraints they face — carbon dioxide is the chief greenhouse gas — so they can plan long term and avoid being hit with dramatic emission limits or penalties in the future.
Now that it is fully accepted that the world is in fact “warming”, steps will be taken to make safe our future. This wont be the last we hear of this story and I’ll keep you informed with each post.
As Always, Keep it Green.
