The lowest level occurred at the Permian-Triassic boundary about 250 million years ago. During the most recent ice age (at its maximum about 20,000 years ago) the world's sea level was about 130 m lower than today, due to the large amount of sea water that had evaporated and been deposited as snow and ice, mostly in the Laurentide Ice Sheet ...
By the end of the 21st century, temperatures may increase to a level last seen in the mid-Pliocene. This was around 3 million years ago. [28]: 322 At that time, mean global temperatures were about 2–4 °C (3.6–7.2 °F) warmer than pre-industrial temperatures. The global mean sea level was up to 25 metres (82 ft) higher than it is today.

Montana is the coldest in continental U.S. history, dropping to minus 70 degrees at Rogers Pass on Jan. 20, 1954. (MORE: Most Extreme U.S. Cold Outbreaks ) 50-states-all-time-cold.jpg
These island countries also have the smallest range between their lowest (sea level) and highest points, and are very sensitive to changes in sea level. The highest and lowest points in China constitute the greatest elevation range within any single country at 9,002 metres (29,534 ft).
This year, scientists have observed a slew of concerning signs for the world’s ice. Antarctic sea ice reached its lowest-ever maximum since scientists began measuring in 1979, a possible sign ...
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] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 is expected to be 1.4 °C above it. [5]
This is the equivalent sea-level pressure; Tosontsengel is located at 1,300 metres (4,300 ft) above sea level. The highest adjusted-to-sea-level barometric pressure ever recorded (below 750 meters) was at Agata, Evenkiyskiy, Russia, elevation: 261 m (856.3 ft)) on 31 December 1968 of 1083.3 hectopascals (hPa) (31.99
