A recent study by American and European climate researchers focusing on warming in the Arctic, published Monday, shows that the "smoking pistol" when it comes to changes in the northern polar region of the world, rapidly heats the air temperature that it has, and will continue to have enormous and negative consequences throughout the globe.
A new article, titled "Key Indicators of Arctic Climate Change: 1971-2017," is the work of scientists at the International Arctic Research Center at Alaska Fairbanks University and the Geological Survey of Denmark and Greenland in Copenhagen.
"The Arctic system departs from the state of its twentieth century and turned into an unprecedented state with consequences not only within the Arctic, but beyond its borders." Jason Boxing, POES
"The Arctic system departs from the state of its 20th century and has grown into an unprecedented state that has implications not only within the Arctic, but also beyond its borders," said Jason Boxing, lead author of the study. "As the atmosphere in the Arctic warms up faster than elsewhere in the world, weather conditions in Europe, North America and Asia are becoming more stable, resulting in extreme weather conditions. Another example is the disturbance of the ocean circulation, which may further destabilize the climate: for example, cooling across the northwest Europe and boosting the storm.
John Walsh, chief scientist at the AUF Research Center, called the Arctic Air Temperaments a "smoking gun" discovered during the study.
"I did not expect the temperature to be as strong as it was," Walsh said. "All variables are temperature dependent. All components of the Arctic system are involved in this change."
The study published on Monday as a flagship issue of a special issue on climate change in the Arctic, published by the journal is the first of its kind, which combines observations of physical climate indicators ̵
This is a three and a half minute video collected by a research team, explaining in detail his methodology and conclusions:
A new study comes after temperature records in the polar regions continue to violate recording after recording. Last week, climatologists reported that Alaska experienced the highest temperatures in March
The global temperature last month was 27 ° F on average, 4 degrees higher than a record high of 1965. at Alaska University, Fairbanks said : "We are not just passing the last record, it destroys records."
Also last month as General dreams This is reported in a large-scale report that winter temperatures in the Arctic are already "blocked" in such a way that a significant increase in sea level in this century is inevitable. with acidification of the ocean, pollution and thawing of permafrost threaten the Arctic and more than four million people inhabiting it, including 10% of the indigenous population. But, as UNEP Executive Director Joyce Msway noted at that time, "what's happening in the Arctic is not left in the Arctic."
This warning was repeated by researchers who stood for a new study on Monday. Their hope is that the findings on air temperatures and delicate interactions between the climate and other natural systems in the Arctic will provide the foundation for a more integrated understanding of the Arctic and its role in the dynamics of Earth's biogeophysics.
