Climate change is an acute threat to poorer people across the world, with the power to push more than 100 million people back into poverty by 2030.  The poorest regions of the world – Sub-Saharan Africa and South Asia – will be hit the hardest. Targeted action is needed to help people cope with climate shocks, such as developing early warning systems and flood protection, and introducing heat-resistant crops.  At the same time, efforts to reduce emissions should accelerate, and be designed to protect the poor.
