The maximum measurement taken last Saturday was 14.33 million square kilometers and was 80,000 square kilometers less than the previous peak registered in 2017, the National Snow and Snow Center said.
He Arctic sea ice He has recorded his low winter accumulation since the posts started 47 years ago. About it The dangerous sign of climate change can have consequences worldwideA team of scientists said Thursday.
The Arctic reaches its maximum sea ice thickness in March every year, and then six months starts the shore season. National Snow and Snow Data Center He pointed out that the maximum measurement taken last Saturday was 14.33 million square kilometers.
“An increase in the Temperature What is on the planet Causing snow downtime“The scientist specializes in snow data. Walt Mier.” Sea ice, in particular, is very sensitive. Thus, about 31 degrees Fahrenheit is the average snow sloping and 33 degrees swimming, ”he added.
The loss of the seawater is an initial warning system
Jennifer Francis, the scientist of the Woodwell Center for Climate Research in the Cape line, said it was another scratched disk -shaped alarm signal. “The disappearance of the sea snow is particularly concerned because this is really an initial warning system Warns us about a series of difficult changes to notice“Francis said in an email.
Arctic warming, scientists confirm the region It warms four times faster than the rest of the worldAffects time elsewhere. Pressure and temperature differences between the north and south are reduced. That Jet weakens the stream on the planeIt moves weather systems, which are often attacked and sinks south with cold sprouts and storms with rain or snowfalls, according to signs of national snow and ice data center and Francis.
“The warming of the winter atmosphere above the Arctic Circle It has an impact on the large -scale weather forms that influence For those outside the Arctic, “Julian Strov, scientist at the University of Manitoba, says.
He pointed out that Strove was not limited to the decrease of the seawater. The remaining snow This summer is better enough to melt quicklySaid Strove. Therefore, he warned that the minimum registration in the winter would not guarantee the minimum registration record in the summer.
According to scientists, the The Arctic Sea Snow TowerEspecially in the summer, it reduces the population of polar bears and makes them weak and hungry, Because they depend on the seawater to hunt. “The winter seafood layer is very important for fishing and sealing meetings,” said Mier.
Sea snow decreases at four stations
The biggest year of the sea snow Arctic 1979, 16.64 million registered square kilometers. This means that the satellites began to monitor him, Arctic’s winter seafood has been reduced to a similar surface to Pakistan.
Walt Mier said that when the Winter Sea does not record the snowfall, more than half of the Earth can extend up to Ecuador, reaching the Gulf of San Lorenzo in Japan, China and Canada. According to the must -have, The extension of the sea snow at four stations decreasesBut the summer is the most important of the general health of the Arctic snow. This is because the snow -free ice is rapidly overheated, which can retain high heat and heat the autumn and winter.
The maximum amount of the maximum Arctic seawater in the winter has occurred since 2015. In the early days of this March, Antarctica Is going to win Low -quantity of sea snow -related record.
In general, Antarctica has more sea ice and both poles have a slightly different calendar. However, “In February, the world marine ice, a mixture of Arctic and Antarctica, which reached a historic minimum,” he concluded.
