It was pretty amusing that yesterday was 91 degrees in southern california and yet it's the middle of november, but I'm the last one to assume it's 100% because of global warming like many others are running around here spouting, since that's a bit simplistic.
There are so many metrics and variables that make up global climate and it's associated fluctuations; no one guy from any agency has the answers any more than L. Ron Hubbard has all the answers. Warehouses full of Cray supercomputers are even brought to their knees when crunching the vast amounts of data needed for climate simulations in the pursuit of determining culprits.
I think climate change, like religion, is simply a case of not having enough data and information to be able to know exactly what's going on. However that shouldn't stop us from just assuming the worst and erring on the side of caution that man's doing is a significant factor in the changes.
Trying to get various governments in the world a bit more eco-aware does seem a bit like herding cats though. China for example cares not one fuck about their massive carbon footprint which is probably the biggest of any country.
