A New Way to Assess ‘Global Warming Potential’ of Short-Lived Pollutants

Comparing greenhouse gases with each other using GWP* preserves the link between emissions and warming or cooling of the atmosphere. Therefore, GWP* is better suited than GWP100 to assessing whether the world is on track to limit warming to well below 2C.

What Would a Global Warming Increase of 1.5 Degrees Be Like?

The Paris climate conference set the ambitious goal of finding ways to limit global warming to 1.5 degrees Celsius, rather than the previous threshold of 2 degrees. But what would be the difference between a 1.5 and 2 degree world? And how realistic is such a target?
