If the warming exceeds - or thereabouts, there is a significant risk of the entire ice sheet being lost over an estimated 10,000 years, adding up to global sea levels. Warming in the Arctic may affect the stability of the jet stream, and thus the extreme weather events in midlatitude regions, but there is only "low confidence" in that hypothesis.
Knowledge of precise climatic events decreases as the record goes further back in time. The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology.
Massive heat waves across North America were persistent in the 1930s, many mid-Atlantic/Ohio valley states recorded their highest temperatures during July 1934. The longest continuous string of 38 °C (100 °F) or higher temperatures was reached for 101 days in Yuma, Arizona during 1937 and the highest temperatures ever reached in Canada were ...
The Arctic experienced the warmest summer on record this year, contributing to extraordinary wildfires and melting glaciers while threatening the rest of the world with problems including higher ...
Millions of people in the eastern half of the U.S. are scrambling for jackets and gloves as temperatures nosedive thanks to a blast of frigid air from Canada. And the below-average temperatures ...
The Arctic blast has broken dozens of decades-old records across the country this week. On Thursday, low temperatures in Midland, Texas, reached 14 degrees, smashing the previous record of 19 ...
Beginning on January 2, 2014, sudden stratospheric warming (SSW) [dubious – discuss] led to the breakdown of the semi-permanent feature across the Arctic known as the polar vortex. Without an active upper-level vortex to keep frigid air bottled up across the Arctic, the cold air mass was forced southward as upper-level warming displaced the ...
Maximum temperature map of the United States from 1871-1888 Minimum temperature map of the United States from 1871-1888.. For the United States, the extremes are 134 °F (56.7 °C) in Death Valley, California in 1913 and −79.8 °F (−62.1 °C) recorded in Prospect Creek, Alaska in 1971.
