There's no doubt the earth is warming. We argue too much over the cause... instead of whether we can do anything to help slow it.

But there is very little proof it's mankind's fault, (it's a lot of supposition, I personally think it's more about solar activity...) but that allows the conversation to waver from the issue of what we can do to be prepared.

One issue is... will it actually help the forests and jungles. Hotter won't mean drier, it'll mean wetter, all that extra icemelt will end up in the air as the less saline ocean surfaces evaporate more readily. More rain, more humidty. The big deserts, like the Sahara, might become savannahs again.

On the other hand, the change in ocean salinity can also cause major currents, such as the gulf stream, to "stall." When that happens... we experience ice-ages. Yes my friends, global warming could lead to the next iceage.
