Population on a warming planet

The idea of the 'greenhouse effect' goes back to the mid 1800s but back then, it was a theory. Now we know it's real. The evidence has been clear for a long while, so what's happening?

But is it all gloom - what can we actually do? And how do we connect with....political...leadership?
