I wrote newspaper articles professionally for seven years, and I love newspapers.

The insistence on complete certainty about the full details of global warming-the most serious threat we have ever faced-is actually an effort to avoid facing the awful, uncomfortable truth: that we must act boldly, decisively, comprehensively, and quickly, even before we know every last detail about the crisis. Those who continue to argue that the appropriate response is merely additional research are simply seeking to camouflage timidity or protect their vested interest in the status quo.

Well-established theories collapse under the weight of new facts and observations which cannot be explained, and then accumulate to the point where the once useful theory is clearly obsolete.

There are some bright spots, to be sure, but the internet is still in a Wild West phase, as was the case during the early age of the printing press as well.

Although I have a variety of obligations, the climate crisis is my central concern.

The crisis is a concrete threatening reality today. It stands to get catastrophically worse unless we take action before the accumulation [of] this global warming pollution reaches such toxic levels that the problem becomes bigger than we can solve.

The struggle against poverty in the world and the challenge of cutting wealthy country emissions all has a single, very simple solution... Here it is: Put a price on carbon.
