The science is crystal clear: we humans are the primary cause of global warming, and we face a bleak future if we fail to act quickly.

Conservative Denyers and Delayers are the main reason America lacks the consensus and the political will to take up the fight against catastrophic climate change.

Since 1955 the oceans have absorbed roughly twenty times more heat than the atmosphere.

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

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

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.

The great political tragedy of our time is that conservative leaders in America have chosen to use their superior messaging and political skills to thwart serious action on global warming.
