According to The Ecologist, the technological fixes for global warming are untested, dangerous, expensive, and probably ineffective. (See the chart below.)
This may all be true, but as more than one scientist pointed out at this year's American Geophysical Union conference, if the news about global warming is as bad as some fear, we really may not have a choice but to begin to research these technologies.
Now Chris Mooney, probably our best young science journalist, writes a column on "When Will Geo-Engineering Tip?" for Science Progress (here). This will not make The Ecologist happy, I predict...
...for me the surprise is that Mooney argues that geo-engineering will likely be "cheap." To which one can only ask the old jazz question: Compared to what? But to be fair, as Jeff Masters of Wunderblog reported from the AGU this year, some possible solutions do look reasonably priced...if goofy.
