per year by 2100 can be prevented by aggressively reducing greenhouse gases.
Most of the sunlight that hits the earth is reflected back into space, but some is trapped by the earth’s greenhouse gases (GHGs), which warms our planet. However, as more and more GHGs are released into our atmosphere, too much heat is being absorbed, raising the temperature of the earth.
Sixty percent (60%) of the emissions from burning fossil fuels (crude oil, coal, and natural gas) stay in the air.
By burning fossil fuels for energy, human activities have increased the concentration of Carbon Dioxide (CO2) in the atmosphere by more than 40 percent since the start of the Industrial Revolution (1760).
