We might never do solar geoengineering. But government science advisers say studying it is better than flying blind.

To avoid the most disastrous sea-level rise, storms, heat waves, and drought, the best available science says that greenhouse gas emissions must be cut in half in the next decade or so and brought to net-zero by the middle of the century.

But even if global leaders acted to cut emissions at that breakneck pace — which none currently has — many of those catastrophic outcomes could still occur. The science of human-caused climate change is unequivocal, but the science of projecting how bad things will get, how quickly, is soaked in uncertainty. […]
