Natural changes may briefly offset global warming
Recent increased attention to global warming is very welcome. But much of it is misplaced. We focus too much on complex climate models, which ask things like how far emissions will increase carbon dioxide concentration, how much that will raise temperatures, by when, with what consequences to climate and geography, and how likely new information will invalidate model results. Together these questions can paralyze us with uncertainty.
