If the global average temperature rises more than 2°C above pre-industrial levels, significant negative impacts of climate change will be more likely and the cost of managing them will rise sharply.

The UK can’t make this happen on its own - the government has to work at an international level to make sure all countries do what is needed to reduce greenhouse gas emissions.
