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*

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)
