This document provides key points on risks to ecosystems, food security and sustainable development associated with 1.5°C warming. It also provides responses to arguments commonly made against 1.5°C and provides the scientific evidence for each point made.

This briefing note outlines the scientific conditions under which warming can be limited to well below 2°C over the 21st century, and return to below 1.5°C by 2100.

This briefing explains why initial and successive 5 year commitment periods for all governments are a necessary element of the new agreement to help ensure that the 1.5/2°C limit is met, and how a 10 year commitment period would in fact fail to provide the long-term stability and certainty that governments seek.

This report presents different approaches to the distribution of mitigation efforts and compares results to the contributions that some governments submitted to the UNFCCC ahead of the climate conference in Paris.

The Climate Action Tracker finds that, if climate plans were fully implemented, they would bring the projected warming to 2.7°C – an improvement of 0.4˚C since the last assessment of pledges at the Lima talks in December 2014.
