In 1959, when humans began measuring the carbon-dioxide concentration in the atmosphere, there was still some margin. That first instrument, set up on the side of Hawaii’s Mauna Loa volcano, showed that the air contained about three hundred and fifteen parts per million of CO2, up from two hundred and eighty ppm. before the Industrial Revolution. Worrisome, but not yet critical. In 1988, when the NASA scientist James Hansen first alerted the public to the climate crisis, that number had grown to three hundred and fifty ppm, which we’ve since learned is about the upper safe limit. Even then, though, we had a little margin, at least of time: the full effects of the heating had not yet begun to manifest in ways that altered our lives. If we’d acted swiftly, we could have limited the damage dramatically.
