A book for understanding in depth the mechanisms behind global warming.

Increasingly frequent heatwaves, ever-stronger storms and rain, melting icecaps, rising waters: natural phenomena largely linked to global warming. And yet there's still always someone who'll say, "How can there be global warming if this winter's colder?" isn't there? Or even, "It's not because of humans, it's just the sun!" We call these people climate skeptics. But who are they, really?
What is the different between climate and the weather? Why does everyone keep talking about 2°C being the threshold of no return? What are the impacts of greenhouses gases? The economic, sociological, and political stakes? What can we do?
