Tom Fudge : Global warming is something we should all be concerned about, and the good citizens among us have tried to make a difference through buying hybrid cars, taking public transportation, or reducing home electricity use.
But what if that's not enough? As hard as we try, and as much as governments may actually do the right thing, reducing carbon dioxide emissions may fall short. We still may face a future of rising temperatures, rising sea levels, species extinction, water shortages, and the many things that global warming could bring.
But there is an optional approach to drastically reducing emissions. It involves actually cleaning up the atmosphere. Building structures that can suck carbon dioxide out of the air and bury it in the ground. The technology may actually be there. But do we have the money and do we have the political will to do it?
You can hear Wally Broecker speak about solving the global warming problem this Wednesday, May 14, at 11 a.m. at the Scripps Institution of Oceanography.
