Alaska's interior is well known for brutal cold and 54 years ago today its temperature plunged to America's all-time record low. The temperature hit minus 80 degrees at Prospect Creek Camp, Alaska ...
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.
According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. 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.
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.

Temperatures measured directly on the ground may exceed air temperatures by 30 to 50 °C (54 to 90 °F). [6] 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 ]
The European Union’s Copernicus Climate Change Service confirmed the record Friday, announcing that according to its analysis, 2024 was the first full year in which global temperatures exceeded ...
Solar luminosity was 30% dimmer when the Earth formed 4.5 billion years ago, [14] and it is expected to increase in luminosity approximately 10% per billion years in the future. [ 15 ] On very long time scales, the evolution of the sun is also an important factor in determining Earth's climate.
Some temperature information is available through geologic evidence, going back millions of years. More recently, information from ice cores covers the period from 800,000 years ago until now. Tree rings and measurements from ice cores can give evidence about the global temperature from 1,000-2,000 years before the present until now. [9]
