A message to the climate sceptics

Right now as a society we are engaged the biggest gamble of all time, a bet that the global warming canaries are wrong, climate change is all natural and inevitable and that there's nothing we can or should do.

We already have more extreme weather events in the last 20 years than in recorded history. There are natural weather cycles, but the changes are now so rapid and so unpredictable that our economies and our ability to feed ourselves is at risk, both here and in developing countries.

Any money we spend on aid or development programmes will be useless if the ecosystems around them collapse.

Personally, I'd rather we act now and risk having been wrong than do nothing about climate change and watch entire habitats and nations collapse, and wonder if we could have helped.
