The global average and combined land and ocean surface temperature show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on multiple independently produced datasets. [26] : 5 The trend is faster since 1970s than in any other 50-year period over at least the last 2000 years.
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. [1] For ninety years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading.
The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan. [8] The theoretical maximum possible ground surface temperature has been ...
BY SETH BORENSTEIN. July 23, 2024 at 5:08 PM. WASHINGTON (AP) — On Sunday, the Earth sizzled to the hottest day ever measured by humans, yet another heat record shattered in the past couple of ...
Global surface temperature (GST) refers to the average temperature of Earth 's surface. It is determined nowadays by measuring the temperatures over the ocean and land, and then calculating a weighted average. The temperature over the ocean is called the sea surface temperature. The temperature over land is called the surface air temperature.
Before July 3, 2023, the hottest day measured by Copernicus was 16.8 degrees Celsius (62.2 degrees Fahrenheit) on August 13, 2016. In the last 13 months that mark has now been beaten 59 times ...
Climate change feedbacks are natural processes which impact how much global temperatures will increase for a given amount of greenhouse gas emissions. Positive feedbacks amplify global warming while negative feedbacks diminish it. [2] : 2233 Feedbacks influence both the amount of greenhouse gases in the atmosphere and the amount of temperature ...
Reconstructions of global temperature of the past 2000 years, using composite of different proxy methods. In the study of past climates ("paleoclimatology"), climate proxies are preserved physical characteristics of the past that stand in for direct meteorological measurements and enable scientists to reconstruct the climatic conditions over a longer fraction of the Earth's history.
