...annual World Health Day to the intersection between disease and global warming. The message is that severe climate change could fundamentally weaken global public health, that doctors need to be ready to deal with the consequences - and that there is a moral case to be made for reducing carbon emissions to save future lives. "If you look at climate change over the long term, it will profoundly affect the pillars of public health: water, sanitation, air quality and sufficient food," says Dr. David Heymann, Assistant Director-General for Health Security and Environment at WHO. "The fact is that human health...
...marine systems [March 24]. Governments should agree to heavy regulation of any field experiments in their waters, and similar international controls should be put into place. Instead of seeking ways to mitigate the effect of greenhouse gases, policymakers should attack the problem head-on by regulating industry and reducing carbon dioxide emissions. The solution to global warming is to stop putting greenhouse gases into the atmosphere. Anything short of this is an imperfect and flawed approach that will ultimately fail.

...much is a rain forest worth? Until recently the answer was: virtually nothing. A tropical rain forest provides habitat for untold species of animals and varieties of plants; modulates the climate and helps bring precipitation to land thousands of miles away; sequesters billions upon billions of the greenhouse gas carbon dioxide. But the only market value a forest had were the trees within it, cut down. "Forests fall for a simple reason," says Andrew Mitchell, a conservationist and the founder of the London-based Global Canopy Programme, an umbrella group of forest organizations. "They are worth more dead than alive...
...move is unprecedented. Private companies in the past have been involved in "avoided deforestation," compensating rain-forest nations to refrain from cutting down their trees in exchange for carbon credits. (Some 15 million hectares of rain forest are destroyed each year, accounting for some 20% of the carbon emissions annually, as burned or cut-down trees release their sequestered carbon into the atmosphere.) But Canopy Capital is the first firm to try to put a market price on all the other ecosystem services provided by a healthy rain forest. Humans have been availing themselves of those services for nothing, like...
...lesson behind the math is that on a warming planet, land is an incredibly precious commodity, and every acre used to generate fuel is an acre that can't be used to generate the food needed to feed us or the carbon storage needed to save us. Searchinger acknowledges that biofuels can be a godsend if they don't use arable land. Possible feedstocks include municipal trash, agricultural waste, algae and even carbon dioxide, although none of the technologies are yet economical on a large scale. Tilman even holds out hope for fuel crops--he's been experimenting with Midwestern...
