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.
This is a list of cities by average temperature (monthly and yearly). The temperatures listed are averages of the daily highs and lows. Thus, the actual daytime temperature in a given month may be considerably higher than the temperature listed here, depending on how large the difference between daily highs and lows is.
[14] Measurement of the spectrum of electromagnetic radiation from an ideal three-dimensional black body can provide an accurate temperature measurement because the frequency of maximum spectral radiance of black-body radiation is directly proportional to the temperature of the black body; this is known as Wien's displacement law and has a ...
September 2023 was the most anomalously warm month, averaging 1.75 °C (3.15 °F) above the preindustrial average for September. [22] The Copernicus Programme (begun 1940) had recorded 13 August 2016, as the hottest global temperature, but by July 2024, that date had been downgraded to the fourth hottest.
On a larger 10-year time frame, which scientists prefer to single years, the world has warmed about 1.19 degrees Celsius (2.14 degrees Fahrenheit) since pre-industrial times, the report in the ...
Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The kelvin is the primary unit of temperature measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Other scales of temperature:
On Jan. 15, 1972, 53 years ago, a weather observer in Loma, Montana, measured a morning temperature of 49 degrees. That sounds warm for mid-January, but that's only half the story.
Minimum temperature map of the United States from 1871–1888 Maximum temperature map of the United States from 1871–1888. The following table lists the highest and lowest temperatures recorded in the 50 U.S. states, the District of Columbia, and the 5 inhabited U.S. territories during the past two centuries, in both Fahrenheit and Celsius.
