Re: Science: Particles seen moving at FTL speeds (CERN)
I don't follow the "droughts are nothing new" logic. Traffic accidents aren't new either but we keep inventing things like air bags and crumple zones and we're better for it. Here we have an opportunity to at least reduce the intensity of future droughts and avoid trillions of dollars in flooding, storm surge damage, and/or dike building. All of which will be borne by the taxpayer.
The other issue is that while the climate has warmed in the past, this time the change is extremely abrupt (relatively speaking). That will make it very hard on existing ecosystems, and it's possible that the rate of change is so fast that it could cause certain ecosystems to crash--coral reefs, for example, are at particular risk.
There is also the possibility of feedback loops causing the rate of warming to accelerate. Melting ice caps lower the overall albedo of the planet, causing it to absorb more solar energy. The Siberian permafrost could melt, releasing vast quantities of methane into the atmosphere and increasing the greenhouse effect. Will these come to pass? Maybe, maybe not, but I'm not anxious to find out either way.
