The latest computer modeling I've seen indicates that at mid-century, there might be 150 million people classified as "environmental refugees."

For the first time in 150 years, the USDA reported there were more farms in America, not fewer. That has to make you happy.

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.

It is unbelievably sad and ironic that the first victims of global warming are almost all going to come from places that are producing virtually none of the problem.

For those of us who worry more about working people than about windfall profits for oil companies, it may net out. A better question is: what does it do to our economy if we manage to overheat the earth? This summer's drought provides a small taste.

One degree turns out to be enough to really unhinge all sorts of earth's ecosystems.

There hadn't really been a climate movement, per se. I think everyone spent twenty years thinking that if we just keep pointing out that the world is on the edge of the greatest crisis by far it's ever come to, then our leaders will do something about it. And it turned out that was wrong. They weren't going to do anything about it.
