Global Warming: A Will to Act?

(www.nytimes.com)

Nicholas D. Kristof (column, April 18) points out a scary scenario of warming oceans releasing gigatons of global-warming pollution. This would speed global warming, which would heat the ocean and potentially release even more pollution.

Mr. Kristof gives just one example of what climate scientists call feedback loops, but many others are already happening.

As global-warming pollution has increased, temperatures have climbed, especially in the Arctic. Those high temperatures have melted centuries-old permafrost, unlocking global-warming pollution from the frozen ground and releasing it into the atmosphere.

There, it causes more global warming, which melts more permafrost, which releases more global-warming pollution. This frightening spiral is happening and is worsened by rising United States emissions of global-warming pollution.

Congress needs to pass a science-based bill that places mandatory limits on global-warming pollution and encourages increased efficiency, conservation and the use of renewable energy.
