Could Geo-Engineering Cool Our Warming Planet?Download audio (MP3)
In a report released this week, the Intergovernmental Panel on Climate Change said it will take very ambitious efforts -- a reduction in greenhouse gas emissions by up to 70 percent by 2050 -- to keep climate change at acceptable levels. The dire predictions have some asking whether it's time to think about geo-engineering: an attempt to use large-scale, high-tech methods to cool the planet. These ideas have included launching giant mirrors into space or fertilizing the oceans with iron to stimulate phytoplankton growth.
