Global mean warming reached 1°C above preindustrial for the first time. It is a signal from the climate system that time is running out if we are to be able to reduce emissions fast enough so as to hold warming below 2°C, and ultimately below 1.5°C by 2100.

This paper analyses “fair and adequate” emission reduction ranges for 2025, 2030 and 2050 for Brazil, India and South Africa, largest economies and a set of African countries.

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.
