Time is short. We have at most a decade to sharply reverse course.

In 2003... the White House conspired with an oil-company funded think tank to block a major government scientific report that sought to spell out the dangers of climate change to Americans.

When people ask me what they should do, I reply, "Get informed, get outraged, and then get political."

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.

The first few feet of sea-level rise alone will displace more than 100 million people worldwide and turn all our major Gulf and Atlantic coast cities into pre- Katrina New Orleans - below sea level and facing super-hurricanes.

In 2005... Mumbai, India, saw that country's most intense recorded instance of rainfall - 3 feet of rain in twenty-four hours.

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