Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will make an assessment of the effect of a four degree rise in global temperatures on (a) the UK's security, (b) the UK's economy, (c) global security and (d) the global economy.

The Intergovernmental Panel on Climate Change’s Fifth Assessment Report states with high confidence that a four degree rise in global temperatures would have severe and widespread impacts on unique and threatened systems, cause substantial species extinction, pose large risks to global and regional food security, and the combination of high temperature and humidity would compromise normal human activities.

The Government prepares a UK Climate Change Risk Assessment (CCRA) every five years, followed by a National Adaptation Programme, which sets out actions to address the risks identified in the CCRA.

The second CCRA was published in 2017.
