...There is a crack in the U.S. financial system, but it's important to ask where the water that caused the crack came from," says Caballero. "The only way to really make the U.S. system resilient to systemic shocks is to fix the supply side...
Most of the fallout from climate change is likely to be disruptive, to put it mildly. It's hard to put a positive spin on rising seas, increased drought and wildfires, shrinking water supplies and more acidic oceans. For the plants that form the very foundation of the food chain, though, an argument can be made that both global warming itself and the rising carbon dioxide levels that cause it are actually a good thing. CO2, after all, is essential for the photosynthesis that most plants depend on for nourishment. And as winters get milder and shorter, plants will have...
...author on a major 2007 review of how plants and climate interact, "while there's pretty clear evidence that CO2 helps plants, there's plenty of debate about how much it helps." One reason is that plants depend not only on carbon dioxide for healthy growth, but also on water and other nutrients. Increase CO2 without increasing the other factors, and you can get plants that are bigger, but relatively deficient in, say, nitrogen - meaning insects may have to eat more of each plant to stay healthy themselves. Some FACE experiments look at the effects of variations in rainfall...
...season" - which, if the Finnish study is correct, won't necessarily help forests, but could be good for crops, since you can deliberately plant seeds that are suited to long summers. But in arid parts of the tropics, he says, where plant growth is limited by the availability of water, more frequent droughts could make things worse. "Large parts of the world," says Field, "are already at the warm edge of where things like to grow...
