What Has Become Clear From The Science

We Have At Most Ten Years—not Ten Years To Decide Upon Action, But Ten Years To Alter Fundamentally The Trajectory Of Global Greenhouse Emissions.

It's As Certain That As Long As Fossil Fuels Are The Cheapest Energy, We Will Just Keep Burning Them.

We Have Known Since The 1800s That Carbon Dioxide Traps Heat In The Atmosphere. The Right Amount Keeps The Climate Conducive To Human Life.

A Level Of No More Than 350 Ppm Is Still Feasible, With The Help Of Reforestation And Improved Agricultural Practices, But Just Barely - Time Is Running Out.

How Long Have We Got? We Have To Stabilize Emissions Of Carbon Dioxide Within A Decade, Or Temperatures Will Warm By More Than One Degree... We Don't Have Much Time Left.
