Month: January 2021

Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s. Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane.

Fossil fuel emissions from human activity are driving up Earth’s temperature—yet something else is at work. The warming has set in motion nature’s own feedback loops which are raising temperatures even higher.
