The Arctic has a steady warming to push the region into a "uninterrupted country" and its " increasingly influential on the United States of continental, scientists said Tuesday.
"We are seeing this continuous improvement of warmth over the entire Arctic system," said Emily Osborne, an officer with the National Ocean Administration and Change, which provided annual evaluation of group on the state of the region, the "Card Report Art."
The Arctic has been warmer over the past five years since at any time since the beginning of the 1900s, the report found, and the department was twice as warmed as a & # 39; rest of the planet.
Osborne, the leading editor of the report and manager of the NOAA Arctic Research Program, said the Arctic was "the most ever-ever transliterated in history people. "
In 2018, "heat heating and air temperature continue to disturb long-term change throughout the pole area, and end up the Arctic to an end without land," said At a meeting of the American Geo-American Union in Washington.
The new edition of the report does not provide a radical breakdown with previous installments, but it is shows that troubled movements are made by increasing climate change. Air temperature in the Arctic in 2018 is the second oldest ever recorded, the report said, by 2016.
Susan M. Natali, an Arctic Scientist at the Woods Hole Research Center in Massachusetts who was not involved in the investigation, said another warning was to go wrong; make the report. "Every time you see a report, things will be worse, and we still do not go," she said. "It's up to date that these changes happen, they are visible."
The warmest Atlantic air causes the jet nose to be "very tired and quite unusual," said the researchers. There are links to climate events in other parts of the world, which include severe storms in the last winter in the United States and a cold promise in Europe called "Beast From the East".
The jet nose is usually a kind of lasso spinning lasso that is split and split; introducing the cold air near the cell; A weaker weak stream allows Arctic blasts to travel south in winter and can install weather systems in the summer, among other effects.
"In the United States East where the other section of the wave comes down," said Osborne, "you have the Arctic air teas that go up to the lowest places and causing these winter storms. "
The early warming in the north, known as the Arctic acid, is associated with many factors, including the simple fact that snow and ice are Many of the sunshine appear, and open water, which is darker, causes more heat. How to dry ice-cream, smaller ice and more open water will be creating a "backward loop" of more smash that gradually drives and more open water.
And as Arctic waters increase their amount of freezing, commercial and geo-regulatory effects are: new shipping routes can be open, and there are other country-owned enterprises, including Russia, increasing.
Some of the research findings, provided by 81 scientists in 12 countries, including:
– The highest level of sea ice winter in the region, this year's March, the second lowest level in a 39 year registration.
– Ice continues year after year, and # 39; Creating thick, Arctic areas. This is important because the old ice tends to resist melting; without it, its & # 39; accelerate. Old ice consisted of less than 1 per cent of the Arctic ice pack this year, a 95 per cent decline over the past 33 years.
– Donald K. Perovich, a seagrass expert at Dartmouth College who added to the report, said that the "big story" for this year was in the Bering Sea, in the west side of Alaska, where the level of seabird reached A small table for almost every winter. In two weeks in February, usually when the ice of the sea goes to the sea; Growing, the Sea Bering lost the place of Idaho's size, Perovich said.
– The lack of ice and flow of fluid is aligned with a short extension of algae species in the Arctic Ocean, associated with cumulative fractions that can poison marine life and people who eat marine seafood pollution . The move is north of algae "which means that the Arctic is now vulnerable to genres that are introduced into local communities and ecosystems with little knowledge of its & This issue, "said the report.
– Reindeer and Charibou numbers have fallen by 56 per cent in the last twenty years, which dropped to 2.1 million from 4.7 million. Scientists who watched 22 herdsmen found that two of them had high numbers without falling, but five populFations had fallen by 90 percent "and do not appear they are getting in. "
– Slopes of ocean plastics, which can be carried by sea life, are growing at the top of the plane; planet. "Limitations in remote Arctic Ocean are higher than all other marine sites in the world," said the report. The microplastics also appear in Arctic seagrass. Scientists have found samples of cellulose prototype, used in a & # 39; make fittings, and fragments of plastics used in a bottle cap and packaging material.
"The report card continues to rapidly record the Arctic," said Rafe Pomerance, chairman of Arctic 21, a network of organizations aimed at educating policy makers and others the Arctic climate change. "The erosion marks are so powerful and their goals are so much needed to reduce emissions from all governments to reduce emissions."
