Or that's the version we were told, anyway. The teenagers were called Eric Harris and Dylan Klebold, and their school was Columbine High, an idyllic sounding place nestled between the Denver metropolitan area and the foothills of the Rocky Mountains.
This is because the amount of sunlight the reaches the equator changes very little, although the temperatures do vary somewhat during the rainy season. Measurement: The average surface temperature on Earth is approximately 14Â°C; but as already noted, this varies.
The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6Â° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years.Temperatures are certain to go up further. Despite ups and downs from year to year, global average surface temperature is rising.By the beginning of the 21st century, Earthâs temperature was roughly 0.5 degrees Celsius above the long-term (1951â1980) average.

Climate has changed when the planet received more or less sunlight due to subtle shifts in its orbit, as the atmosphere or surface changed, or when the Sunâs energy varied.
