Careful Where You Put That Tree
Ant writes "Wired News is reporting that according to Stanford University's atmospheric scientist Ken Caldeira, forests in the wrong location can actually make the Earth hotter. From the article: 'Plants absorb large amounts of carbon dioxide during photosynthesis, so scientists and policy makers have long assumed new forest growth helps combat global warming. At an American Geophysical Union conference in San Francisco earlier this month, however, Caldeira rolled out a provocative new finding: Trees may be good at capturing carbon dioxide from the atmosphere, but their dark leaves are also very efficient at soaking up sunlight, which is later released as heat. At certain latitudes, the net effect of these two processes is warming, rather than cooling.'"
Since it is Christmas, I shall be kind to such a response. Mars is experiencing Global Warming.
So is NASA lying? Or don't you believe in their facts?
Strange women lying in ponds distributing swords is no basis for a system of government.
Climatologists have said that at the current rate of global warming a net change in hurricane severity is still quite a ways off.
Katrina was bad only because of where it hit. Any other category 3 would've done the same thing to the Gulf Coast. Hurricane Andrew in 1992 was a category 4 and tore up large chunks of Florida. Not only would Andrew have done to New Orleans what Katrina did, it probably would've been worse, since Katrina was only a category 3 when it hit land for the second time (it was only a category 1 when it hit Florida).
The strongest recorded storm at the time of landfall between 1992 and 2005 was a category 4 (Andrew), not a category 3 (Katrina). Storm severity was worse 13 years ago, when the globe was marginally cooler. Katrina was not a direct result of global warming, it was just an average storm that hit a very ill prepared area.
