Is America like a Frog?

Krugman compares American to frog in the sense that it never realizes the danger it's in while the water is heating and is eventually boiled alive. Creeping disasters are what we are facing these days and as of now we are just sitting while the water is getting hotter. We face disasters in both the economic and environmental realms. While economics are pointing to a second wind of the Great Depression the environmental points towards a total catastrophe in climate change. Krugman points out that climate change is "a creeping threat", the catastrophe will not be apparents for a while and then it will be too late. It's puzzling why the country won't take action when the president and the Congressional leadership now exactly what is happening.
Krugman uses this article as a "here's what's happening, what are you doing to fix it?" article. His analogy of boiling a frog gets across his hopelessness and view of the country's future.It is also a nice visual for the reader.He has a nice balance of facts and opinion.He ends the article by stating he doesn't know the solution, making the reader think about how they themselves might fix it, and again showing his hopelessness.
