June 25 - Rising emissions of heat-trapping greenhouse gases are widely blamed for causing global warming, and risk more extreme weather and higher sea levels.

The table below shows:

(1) annual global carbon dioxide (CO2) emissions, in billions of tonnes, from burning fossil fuels and making cement

(2) annual CO2 emissions from deforestation, after allowing for tree planting

(3) concentrations of CO2 in the atmosphere, in parts per million

(4) global greenhouse gas (GHG) emissions, in billions of tonnes of CO2 equivalent

(5) rank among 50 hottest years since 1850

Note: Levels of ozone-depleting gases have plummeted since the phase-out starting in 1987. Excluding these, other greenhouse gas emissions rose much faster in the 1990s.
