A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters
The Arctic's indigenous people have a long relationship with its icy conditions, and face the loss of their cultural heritage. Further, there are numerous implications which go beyond the Arctic region. Sea ice loss not only enhances warming in the Arctic but also adds to global temperature increase through the ice-albedo feedback.
The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September. Arctic Sea ice maximum is the day of a year when Arctic sea ice reaches its largest extent near the end of the Arctic cold season, normally during March. [14]
Shockingly cold air funneled directly from the Arctic will be making an unwelcome appearance across nearly the entire eastern half of the country this weekend and into early next week, forecasters ...
The year 2023 brought a brief period of record cold, flooding, a soggy summer and tornadoes to Southern New England. The National Weather Service captures the weather highlights (or maybe they ...
The 24-hour daylight of the Arctic summer attracts visitors from afar, including huge flocks of seabirds like the crested auklet. A male must use both his song and a secret tangerine perfume if he is to attract a mate. For the resident walrus, the summer heat can be unbearable. After hauling himself to the beach to moult, an old male uses an ...
The most common way to get hypothermia is being exposed to extremely cold temperatures. When you’re expecting to see temperatures like Kansas is preparing for, it’s good to be well-versed ...
In the negative phase when pressure differences are low, cold Arctic air can then easily penetrate southward through Europe without being interrupted by the usual westerlies. Model calculations show that the air pressure difference with decreased sea ice cover in the Arctic summer is weakened in the following winter, enabling Arctic cold to ...
