High-level UN working group says 2°C warming limit is too high

Experts have revealed that limiting global warming to 2°C is feasible and will bring about many co-benefits, but poses substantial technological, economic and institutional challenges. The experts urge that the 2 °C limit should therefore be seen as a line that needs to be stringently defended. Less warming would be preferable and efforts should be made to push the defence line as low as possible.
