Carbon dioxide leads to global warming

Fastest global emissions rate ever means carbon dioxide levels will never fall below 400ppm in our lifetimes

In 2014, carbon dioxide levels reached 400ppm in the Northern Hemisphere for the first time in human history. Historically, however, CO2 in the atmosphere varies on a yearly basis slightly up or down, drawing a saw-tooth plot. But in 2016, El Niño will drive an increase of 3.15 ppm or one point above the 2.1 ppm baseline average.

Our only shot to avert potentially catastrophic global warming once we pass the 500ppm threshold is to bring global emissions near zero as fast as possible, coupled with carbon negative technologies like carbon capture and sequestration. Stopping deforestation is one of the cheapest and readily available low-tech solutions at our disposal.
