Adapting to the impacts of climate change

Beyond doing everything we can to cut greenhouse gas emissions and slow the pace of global warming, we must adapt to the unavoidable impacts of climate change.

We must match an accelerating crisis with accelerating action. Match the revolution in energy with a revolution in finance. And match rising impacts with rising protection.
