Under the Paris Agreement, almost all governments worldwide have agreed to collectively limit global warming to 'well below' 2°C above pre-industrial temperatures, and to 'pursue efforts' to limit this warming to 1.5°C. However, there has been 1°C of warming to date, and current international pledges could result in 3°C or more. A 2018 UN Special Report examined how peak global warming could be limited to 1.5°C above pre-industrial temperatures, and the implications of doing so. This POSTnote outlines key messages from the UN Special Report, and UK responses to preventing and adapting to climate change.Jump to full report >>
The UN Special Report found that:
IPCC experts suggest that in any case, the emissions reductions required imply "rapid, far-reaching changes on an unprecedented scale" to all sectors of the economy.
The UK Government has climate policy in place for mitigating against and adapting to climate change.
