(x). Earth's Climatic History Earth's Climatic History. Climatologists have used various techniques and evidence to reconstruct a history of the Earth's past climate. From this data, they have found that during most of the Earth's history global temperatures were probably 8 to 15 degrees Celsius warmer than today. In the last billion years of climatic history, warmer conditions were broken by glacial periods starting at 925, 800, 680, 450, 330, and 2 million years before present.

Global Temperature Trends From 2500 B.C. To 2040 A.D. To 2040 A.D. By Climatologist Cliff Harris and Meteorologist Randy Mann Article and Chart Updated: April 9, 2014. Until the early to mid 2000s, global temperatures were more than a degree Fahrenheit warmer when compared to the overall 20th Century mean.From August of 2007 through February of 2008, the Earth’s mean reading dropped to near the 200-year average temperature of 57 degrees.ased on these predictions, it appears that much warmer readings may be expected for Planet Earth, especially by the 2030s, that will eventually top 1998's global highest reading of 58.3 degrees. It’s quite possible we could see an average temperature in the low 60s.

History of Changes in the Earth's Temperature The earth's average temperature rose by 0.8 °C (1.5 °F) during the last century. That change is in the mean global temperature that has been calculated for each year since 1880. The history of average global temperature is based on data gathered around the world at weather stations, on ships and by satellites. These records clearly show that the first decade of the 21st century was the warmest since the 1880s, and the first decade that the earth's average annual temperature rose above 14.5 °C (58 °F).

Global warming controversy According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880.The global mean surface air temperature for that period was estimated to be 14°C (57°F), with an uncertainty of several tenths of a degree.) In other words, the maps show how much warmer or colder a region is compared to the norm for that region from 1951-1980.

Does CO2 always correlate with temperature (and if not, why not?) According to an ongoing temperature analysis conducted by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8° Celsius (1.4° Fahrenheit) since 1880. Two-thirds of the warming has occurred since 1975, at a rate of roughly 0.15-0.20°C per decade.
