Heat is the number one weather related killer, and as carbon pollution continues, global … Read More

Negative Emissions Key to Meeting 2°C Threshold

Negative Emissions Key to Meeting 2°C Threshold

Humans will have to not only stop emitting greenhouse gases by 2085, but also develop technology that will result in negative emissions — the removal of 15 billion tons of carbon dioxide from the atmosphere each year by the end of the century — in order to prevent global warming from exceeding 2°C (3.6°F), according to a new study. … Read More
