THE SUM OF human tinkering with the climate since the beginning of the industrial era is sometimes likened to a planetary science experiment. That captures the magnitude of what is happening and the unpredictability of its results, yet it is also misleading. Global warming is not an experiment, because it is not intentional.

Mankind has not really started experimenting with the climate yet.

But perhaps, given the slow progress in keeping down emissions, it should.
