Records of global average surface temperature are usually presented as anomalies rather than as absolute temperatures. A temperature anomaly is measured against a reference value (also called baseline period or long-term average). [42] Usually it is a period of 30 years. For example, a commonly used baseline period is 1951-1980.
Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
Hawaii is the only state to not record a subzero temperature: The coldest temperature recorded in Hawaii is 12 degrees at the Mauna Kea Observatory, at an elevation of 13,796 feet, on May 17, 1979.
The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890. The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4]
Here's a statistic: On Earth, 18 of the last 19 years have been the warmest in recorded history. And as both NASA and the National Oceanic and Atmospheric Administration (NOAA) announced on ...
Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The location of Vostok Station in Antarctica. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
The warmest year on record for the U.S. was set back in 2012 when temperature anomalies averaged 3.26 degrees Fahrnheit (1.81 degrees Celsius) above the long-term average. Last year came in as the ...
