The decade from 2000 to 2009 was the warmest in the modern record. “Piecing Together the Temperature Puzzle” illustrates how NASA satellites enable us to study possible causes of climate change. The video explains what role fluctuations in the solar cycle, changes in snow and cloud cover, and rising levels of heat-trapping gases may play [...]
The average temperature of Earth is approximately 15 degrees Celsius, which is about 59 degrees Fahrenheit. Average Earth temperatures are calculated from temperatures taken from all over the planet at different times. Find out how Earth’s average temperature appears to be on the rise with information from a science teacher in this free video on [...]
