- 1
Guy Callendar discovered that the planet had warmed by about 0.3 degrees Celsius over the previous 50 years and believed these changes were a direct result of human activity.

Burning fossil fuels disrupts the natural balance by releasing additional greenhouse gases into the atmosphere, trapping more heat and causing Earth's average temperature to rise.
- 3
Scientists extract ice cores by drilling deep into ice at Earth's poles to determine concentrations of gases in Earth's past atmosphere, revealing that human activity is dramatically increasing the rate of climate change.
