The best thing about improvements in health care is that all the climate-change deniers are now going to live long enough to see how wrong they were.

If our government won't spend the money to protect New Orleans sufficiently today, what are the chances we will spend the money to protect dozens of coastal cities post-2050, once everyone knows that sea levels will keep rising and intense hurricanes will occur relentlessly?

Bush and Inhofe will go down in history with other leaders such as Herbert Hoover and Neville Chamberlain who were blind to their nation's gravest threats.

I've always believed that you should stick as closely to the science as possible. And my biggest advice to reporters has been, if you're doing a climate story, talk to climate scientists. The best climate stories are done by the people who talk to climate scientists.

Hurricane seasons with four or more super-hurricanes, those with sustained wind speeds of 131 mph or more will soon become the norm.

Much of the scientific community has been astonished that their increasingly strong and detailed warnings have been either ignored or attacked.

Some 3 million years ago, when the earth was a little more than 3°C warmer than preindustrial levels (about 2.2°C warmer than today), Antarctica had far less ice and sea levels were a stunning 25 meters higher than today. If we stay on our current emissions path, the planet will almost certainly be that warm by the century's end.
