Shouldn't we err on the side of caution when it comes to man-made climate change? After all, if it's not real and we do something about it, we lose money. But if it's real, and we don't do something about it, we lose lives and possibly species.

The evidence is pretty conclusive that our activities are adversely affecting the earth’s climate and environment. Any positive steps we as a species can take to reduce the output of Co2 and other greenhouse gases can be useful to the larger cause. There is too much at stake to do nothing.

That said, every study done on the changing climate shows we don’t have an unlimited time to consider or defer action before calamity becomes the new norm. The symptoms of environmental peril are evident worldwide, and worsening. 

It is beyond pathetic that the current leaderships of the richest, most powerful economies in the world are fatuously indifferent of the obvious.
