Virtually everyone now concedes that there is significant global warming and that carbon emissions play at least some role. Polar ice has always acted as a gigantic mirror that reflects sunlight back into space. Its erosion creates a feedback loop — less ice, higher temperature, even less ice, even higher temperature — that acts as a cause independently of the level of CO2. We will just have to hope that arresting temperature rise now will allow the glaciers to recover (if they can) and stop the fatal ice loop. Without accompanying their demand for less emissions by endorsing climate engineering, today's youth may be leading us down the road to runaway climate change.
