The laws of Congress and the laws of physics have grown increasingly divergent, and the laws of physics are not likely to yield.

The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.

A spiritual voice is urgently needed to underline the fact that global warming is already causing human anguish and mortality in our nation and abroad, and much more will occur in the future without rapid action.

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

We spend probably more of our time than we should, just because it's close to home, worrying about the West. But it's equally important to figure out how we're going to free up the resources to let the developing world leapfrog the fossil fuel age. That's at least as mathematically important, and at least as morally crucial.

Ice in the West Antarctic and over Greenland, i.e., ice that's over a rock at the moment, that will raise the level of the sea as it slides into the ocean, putting at risk everyone and everything that lives on the coasts, and that includes an enormous percentage of the world's people.

The idea that China and India will just abandon climate action is not true, because they're doing it for more reasons than we are.
