If the sun warms the Earth too dangerously, the time may come to
draw the shade. The "shade" would be a layer of pollution
deliberately spewed into the atmosphere to help cool the
planet. This over-the-top idea comes from prominent scientists,
among them a Nobel laureate.

This weekend, NASA's Ames Research Center in Moffett Field,
Calif., hosts a closed-door, high-level workshop on the global
haze proposal and other "geoengineering" ideas for fending off
climate change.

Unfortunately, we've allowed things to get so out of hand that drastic
measures are probably going to be required. There might still be time to
reverse things without such measures, but I just don't think the
political will is there to really try. So that leaves "geoengineering"
in another 20 or 30 years.
