Persistent Rise Of Air And Sea Temperatures

Global warming refers to the persistent rise of air and sea temperatures. Global temperatures in the 20th century have increased by 0.8 °C (Weart, 2003).

The current state of global warming is mostly related to human causes, as natural causes are rare. Natural causes include volcanic eruptions, changes in solar output, and variation of the earth’s position altering its distance from the sun (Singer
