- To 2040 A.D. Until late 2006, global temperatures were more than a degree Fahrenheit warmer when compared to the 20th Century average. From August of 2007 through February of 2008, the Earth’s mean temperature dropped to near the 20th Century average of 57 degrees.

- Temperature Extremes. Earth's surface temperature depends on how much energy it receives from the sun. The equator, which is in direct sunlight all year, tends to be the hottest place, but the highest air temperature ever recorded was at Death Valley, California, in 1913.It was 56.7 degrees Celsius (134 degree Fahrenheit).ts average surface temperature is following a warming trend. In 2013, Earth's average temperature was 14.6 degrees Celsius (58.3 degrees Fahrenheit), according to NASA.

- History of Changes in the Earth's Temperature. by Liz Osborn CurrentResults.com. 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.

Chilling chart reveals how much the Earth has warmed since 1880 as global temperatures continue to rise Global highlights: July 2016. The July temperature across global land and ocean surfaces was 1.57°F above the 20th century average of 60.4°F. This was the highest for July in the 1880–2016 record, surpassing the previous record set in 2015 by 0.11°F, the previous record holder for the warmest month on record.

- weather and science facts. The world's highest recorded surface temperature is 56.7 °C (134 °F) measured at Greenland Ranch in Death Valley, California, USA on July 10, 1913. The mean temperature in Dallol, Ethiopia is 34.4 °C (94 °F), the highest annual average temperature on earth. Hottest Cities in the World.

UCAR Home About Us News Research+Resources Education For StaffUCAR - University Corporation for Atmospheric Research What is the average global temperature now? Climate scientists prefer to combine short-term weather records into long-term periods (typically 30 years) when they analyze climate, including global averages. Today's global temperature is typically measured by how it compares to one of these past long-term periods. For example, the average annual temperature for the globe between 1951 and 1980 was around 57.2 degrees Fahrenheit (14 degrees Celsius). In 2015, the hottest year on record, the temperature was about 1.8 degrees F (1 degree C) warmer than the 1951–1980 base period. That calculation comes from NASA and NOAA.

2014 in Review: US Average Temperature Rises Above 20th Century Average Again December closed out the year as the second warmest on record with an average U.S. temperature in the lower 48 states of 37.1 F, which is 4.5 F above the 20th century average. December 2014 was the warmest since 1939, the data center said.anuary 10, 2015; 9:02 AM ET. Share |. Above-normal temperatures in the West, Northwest and Southwest United States helped contribute to 2014 being the 18th consecutive year that temperatures exceeded the 20th century average.

Instrumental temperature record The global average and combined land and ocean surface temperature, show a warming of 0.85 [0.65 to 1.06] °C, in the period 1880 to 2012, based on multiple independently produced datasets. The Earth's average surface temperature rose by 7002273890000000000♠0.74±0.18 °C over the period 1906–2005. temperature anomaly is measured against a reference value or long-term average. For example, if the reference value is 15 °C, and the measured temperature is 17 °C, then the temperature anomaly is +2 °C (i.e., 17 °C -15 °C).

- The average surface temperature has risen by 33.4 degrees F (0.8 C) since the 1880s. The highest increases have occurred in just the past few decades. This gradual increase in the average temperature is called global warming.

Record-Setting Weather The highest average annual temperature in the world, possibly a world record, is the 94°F, at Dalol (or Dallol), Ethiopia. The station is in a salt desert and is based on only 6 years of data, October 1960–November 1966. Lugh (or Luuq), Somalia, East Africa has an annual mean recorded temperature of 88°F.

Global warming slowdown 'could last another decade' The Pacific is a symptom of the hiatus but not the ultimate cause. The Atlantic is the driverProf Ka-Kit Tung, University of Washington. According to the Intergovernmental Panel on Climate Change (IPCC), global average temperatures have increased by around 0.05C per decade in the period between 1998 and 2012. This compares with a decadal average of 0.12 between 1951 and 2012.

Global Climate Report - July 2015 As July is climatologically the warmest month of the year globally, this monthly global temperature of 16.61°C (61.86°F) was also the highest among all 1627 months in the record that began in January 1880. The July temperature is currently increasing at an average rate of 0.65°C (1.17°F) per century.

Climate Change: Global Temperature Though warming has not been uniform across the planet, the upward trend in the globally averaged temperature shows that more areas are warming than cooling. Since 1976, every year including 2014 has had an average global temperature warmer than the long-term average. Over this 37-year period, temperature warmed at an average of 0.50 °F (0.28 °C) per decade over land and 0.20 °F (0.11 °C) per decade over the ocean.

- But the paleoclimate record also reveals that the current climatic warming is occurring much more rapidly than past warming events. As the Earth moved out of ice ages over the past million years, the global temperature rose a total of 4 to 7 degrees Celsius over about 5,000 years.In the past century alone, the temperature has climbed 0.7 degrees Celsius, roughly ten times faster than the average rate of ice-age-recovery warming.lacial ice and air bubbles trapped in it (top) preserve an 800,000-year record of temperature & carbon dioxide. Earth has cycled between ice ages (low points, large negative anomalies) and warm interglacials (peaks). (Photograph courtesy National Snow & Ice Data Center.

History of Changes in the Earth's Temperature 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).

- The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years.

- Over the past century, though, global average temperatures have risen from near the coldest to the warmest levels in the past 11,300 years, the 2013 study authors explain.Over this same period, emissions of heat-trapping gases from human activities have increased.hroughout its 4.54-billion-year history, Earth has experienced multiple periods of temperatures hotter than today’s. But as far as the “recent” past, a study published in March 2013 concluded that global average temperature is now higher than it has been for most of the last 11,300 years.

- Immediately before the last ice age-between 130,000 and 117,000 years ago-a natural warming episode known in Europe as the Eemian Interglacial produced global average temperatures 2–3°C higher than those of today, much like what would be expected in our more moderate scenario.

- Last year was the thirty-seventh consecutive year of above-normal global temperature. According to data from NASA, the global temperature in 2013 averaged 58.3 degrees Fahrenheit (14.6 degrees Celsius), roughly a degree warmer than the twentieth-century average. Since the dawn of agriculture 11,000 years ago, civilization has enjoyed a relatively stable climate.

2016 set to be hottest year on record, Met Office say The average global temperature for 2016 is expected to be between 0.72C and 0.96C warmer than the average temperature of 14C. 'This forecast suggests that by the end of 2016 we will have seen three record, or near-record years in a row for global temperatures'.

Global Warming: News, Facts, Causes & Effects While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years.
