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.
[citation needed] During the PETM, the global mean temperature seems to have risen by as much as 5–8 °C (9–14 °F) to an average temperature as high as 23 °C (73 °F), in contrast to the global average temperature of today at just under 15 °C (60 °F). Geologists and paleontologists think that during much of the Paleocene and early ...
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 ]
500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.
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.

Thinking about the unstoppable flow of time and how it changes everything in its path can be unsettling. People have no choice but to grow old, and non-living things get worn down just the same.
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]
