What are we Doing about Climate Change?

Abstract

Climate change is the most important contemporary environmental problem that the world faces, yet it is the subject of many misconceptions. Climate science has been used for political ends and distorted in the press, both intentionally and through ignorance. This article presents an overview of what is known about global warming and what is controversial, about future climate projections and their impacts, and about the emissions responsible for climate change and policies to limit them.
