'Global Warming Has a Fairly Simple and Cheap Technical Solution'

Robert Frank:

Carbon Tax Silence, Overtaken by Events, by Robert Frank, Commentary, NY Times: ...Mitt Romney ... has been equivocal about whether rising temperatures are caused by human action. But he has been adamant that uncertainty about climate change rules out policy intervention. ...
Climatologists are the first to acknowledge that theirs is a highly uncertain science. The future might be better than they think. Then again, it might be much worse. Given that risk, policy makers must weigh the potential cost of action against the potential cost of inaction. And even a cursory look at the numbers makes a compelling case for action. ...
The good news is that we could insulate ourselves from catastrophic risk at relatively modest cost by enacting a steep carbon tax. ... A carbon tax would also serve two other goals. First, it would help balance future budgets. ... If new taxes are unavoidable, why not adopt ones that ... make the economy more efficient? By reducing harmful emissions, a carbon tax fits that description.
A second benefit would occur if a carbon tax were ... phased in gradually, only after the economy had returned to full employment. High unemployment persists in part because businesses, sitting on mountains of cash, aren’t investing it... News that a carbon tax was coming would create a stampede to develop energy-saving technologies. ...
Some people argue that a carbon tax would do little good unless it were also adopted by China and other big polluters. It’s a fair point. But access to the American market is a potent bargaining chip. The United States could ... tax imported goods in proportion to their carbon dioxide emissions if exporting countries failed to enact carbon taxes at home.
In short, global warming has a fairly simple and cheap technical solution. ...
Update: I didn't do a very good job of highlighting Robert Frank's point that we shouldn't "expect to hear much about climate change at the Republican and Democratic conventions," but "Many climate scientists ... are now pointing to evidence linking rising global temperatures to the extreme weather we’re seeing around the planet." Thus, "Extreme weather is already creating enormous human suffering, and "If the recent meteorological chaos drives home the threat of climate change and prompts action, it may ultimately be a blessing in disguise."
