Education. If you want to become an optometrist, you'll need about eight years of education. Depending on how fast you work, you might be able to graduate sooner if you take on additional credit hours or complete coursework during the summer.
Although the results for the Earthâs temperature are usually given as anomalies, climate scientists have used the measured temperature data to calculate average temperatures. NOAAâs result for the 20th century average land-ocean Earth surface temperature is 13.9 Â°C. The 2011 NOAA surface temperature anomaly of 0.51 Â°C, gives an average Earth temperature of 14.4 Â°C for 2011. To find out more about how the Earth is warmed and the greenhouse gases that are responsible, see How Atmospheric Warming Works and Greenhouse Gases.
Temperatures on Earth typically range from 115 degrees Fahrenheit at the hottest to minus 100 degrees at the coolest. The Earth's approximate average temperature is 61... Temperatures on Earth typically range from 115 degrees Fahrenheit at the hottest to minus 100 degrees at the coolest. The Earth's approximate average temperature is 61 degrees. The hottest ever recorded air temperature on Earth was 134 degrees, which was recorded in 1913 in Death Valley, California. The highest recorded surface temperature was higher, reaching 159 degrees in the Lut Desert of Iran in 2004. Antarctica's Volstok Station holds the record for coldest temperature, reading minus 128.6 degrees in 1983.
