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

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.

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?

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.

The last time Earth was 1°C warmer than today, sea levels were 20 feet higher.

The entire western Siberian sub-Arctic region is melting, and it has all happened in the last three or four years.

Do believe that if we fail to act in time, it will be the single biggest regret any of us has at the end of our lives.
