An interesting question is, what are you waiting for?
Global warming is the biggest problem we’ve ever faced as a civilisation — certainly you want to act to slow it down, but perhaps you’ve been waiting for just the right moment.
The moment when, oh, marine biologists across the Pacific begin weeping in their scuba masks as they dive on reefs bleached of life in a matter of days. The moment when drought in India gets deep enough that there are armed guards on dams to prevent the theft of water. The moment when we record the hottest month ever measured on the planet, and then smash that record the next month, and then smash that record the next month? The moment when scientists reassessing the stability of the Antarctic ice sheet have what one calls an ‘OMG moment’ and start talking about massive sea level rise in the next 30 years?
