And what do we do now?

Our world is about to change dramatically. We have already “locked in” global average warming of at least 2 degrees, which will have major impacts on food, water and global security.

Catastrophic outcomes – including economic, social, and ecological collapses – are likely even if, as Gilding expects, we manage to engineer a global emergency response. A world where half of all species becomes extinct is likely if an additional 2 billion people try to live like those in the most developed countries.

With planetary capacity already starkly breached, what happens then? And what do we do now?
