Road to curb temperature rises

The goal of the 2015 Paris Climate Conference, COP21, is to achieve a legally binding, international agreement to keep average global temperatures no more than 2°C above pre-industrial temperatures*

Global mean temperatures above pre-industrial levels

COP21 pledges
are implemented

2010: 193 nations sign Cancun
Agreements committing governments
to “hold increase in global average
temperature below 2°C above
pre-industrial levels”

Warming on existing
emissions-reduction
policies. Low-lying
island states at risk
from rising sea levels

*Accurate assessment of temperatures in 1750s — when industrial revolution began — is difficult. To overcome problem, climatologists use average temperatures recorded between 1850 and 1900. †United Nations Synthesis report on aggregate effect of Intended Nationally Determined Contributions (INDCs)
