Resumen de Call in the clouds
Battersby talks about the essence of the Gaia hypothesis, which was proposed in the 1960s by James Lovelock. Now it appears the world would have warmed a bit more than it has were it not for the aromatic cocktail of chemicals emitted by plants. It turns out this can change the weather--and anything that changes the weather day after day and year after year changes the climate, too. While this new mechanism is nowhere near strong enough to save people from global warming, it may have been stronger in the past when the air was cleaner.
