In 2010 human activity caused 50 Gt CO2e of greenhouse gas emissions.
These emissions were 76% carbon dioxide (CO2), 16% methane (CH4), 8% nitrous oxide (N20) and 2% F-gases.
The big terrestrial emitters were China (23%), the USA (14%), Europe (10%), India (5%) and Russia (5%).
And the primary sources of emissions were energy (35%), industry (18%), transport (13%), agriculture (11%), forestry (11%), buildings (8%) and waste (4%).
The sources are explained in more detail in the balloons above, which technically shouldn’t float so well ;-). These balloons don’t look very threatening, but they represent the large majority of positive climate forcings.
Which in English means they are major causes of climate change.
