Global warming is the overheating of water, air and surface of the Earth.
It causes sea level rise, droughts and puts some species at risk.
The sea level has risen 20 cm in the last 100 years. In the next 100 years it could rise 60 cm.
The production of corn, rice and wheat could decrease by 2% each decade.
Anthropogenic emissions of greenhouse gases trap the sun’s heat in the atmosphere.
The most abundant gas is carbon dioxide (CO2), about 80%: between 1750 and 2014 its concentration has risen by 142%.
The rise is caused by the use of fossil fuels, which has multiplied after the Industrial Revolution.
China is the largest emitter of CO2 in the world: 29%, more than the US and the EU together (15% and 11%).
Between 1880 and 1980, the temperature of the Earth rose 0.3° C.
Between 1980 and 2013 0.6° C.
With an increase between 1° and 4° C, 187 million people will be forced to leave their homes because of flooding.
