Observation of Climate Change
Global warming is caused by anthropogenic activities.
CO2 Emission by Fuel Type
Fossil fuel consumption is increasing rapidly to satisfy growing energy demand after the Industrial Revolution, which started in the late 18th century.
Fossil fuel combustion:
C + O2 → CO2
(Carbon in fossil fuel) (Atmospheric Oxygen)
Atmospheric CO2 Concentration and Temperature Rise
Atmospheric CO2 concentration and global mean temperature are increasing along with the rapid increase of CO2 emission.
