Arctic climate change: the past years By: Dr. Jeff Masters, AM GMT on Febru The Arctic is a region particularly sensitive to climate change, since temperatures are, on average. Over the past 50 years, annual average temperatures have increased by roughly °C (°F) over most of the Canadian Arctic and northwest Greenland, while the Labrador Sea remained cold and nearby areas of Canada and southwest Greenland cooled by up to 1°C (°F).
Last year, a report by the Intergovernmental Panel on Climate Change warned that thawing permafrost, which can lead normally frozen ground surfaces to melt and collapse, threatened to inflict serious damage on several Russian oil and gas facilities in the Arctic that together account for 45 percent of the country’s production capacity. In the Arctic, climate change has been one of the main topics discussed by media, researchers, Arctic inhabitants, and policy-makers for more than a decade. Impacts of climate change on the livelihoods and cultures of the region’s indigenous peoples are at the core of this discourse. As the region warms over twice as fast as the global.
Arctic winter sea ice maximums in , , , and were at record low levels, and the 12 lowest minimum extents in the satellite record have all occurred in the last 12 years. The volume of Arctic sea ice present in the month of September has declined by 75 percent since On this trip you will explore the nature and climate of Greenland first hand. As a polar explorer you will gain amazing experiences and obtain specific knowledge about the fascinating wildlife and climate of .

Climate" refers to much more than just temperature and precipitation. In addition to long-term average weather conditions, climate also includes extreme events, as well as aspects of the system such as snow, ice, and circulation patterns in the atmosphere and oceans.
In the Arctic, sea ice is one of the most important climatic variables. It is a key indicator and agent of climate change. The role of the Arctic Ocean during cool climatic periods. In: Climatic changes in Arctic areas during the last ten-thousand years, pp.

The link between the two is thin at best. Most droughts and famines occurred during cold periods. McMichael concludes with a lengthy statement: “Human induced climate change is beyond by: The Arctic is warming at a rate of almost twice the global average. Without urgent action to cut greenhouse gas emissions, the world will continue to feel the effects of a warming Arctic: rising sea levels, changes in climate and precipitation patterns, increasing severe weather events, and loss of fish stocks, birds and marine mammals.
She’s spent the last nine years studying permafrost carbon and its potential to exacerbate climate change. Christina Schädel. Photo: Courtesy. We talked with Schädel, who also co-leads the Permafrost Collaboration Team of the Interagency Arctic Research Policy Committee, about the climate risks and whether we’ve passed a key tipping point.
In the 10 years since "An Inconvenient Truth" was released, climate researchers have made great progress in predicting how rising temperatures will. Due to climate change the Arctic is heating up twice as fast as anywhere else on the planet, shrinking the Arctic sea ice cover by 14% per decade.
Compared to the median sea ice cover recorded betweenwe have lost aboutsquare miles, an area. Periods with warmer temperature than present occur approximately ev years. The most recent ten thousand years andyears ago were generally warmer than the time interval between them.
The most recent millennium ( years) is the warmest in the pastyears. The extent of area covered by Arctic sea ice is an important indicator of changes in global climate because warmer air and water temperatures are reducing the amount of sea ice present.
Because sea ice is light-colored, it reflects more sunlight (solar energy) back to space than liquid water, thereby playing an important role in maintaining the.
There is great urgency, however, to the problem of climate change, especially in the Arctic, a region warming at more than twice the global average rate.
Asking the right questions in the Arctic is both urgent and important for correctly defining climate problems globally.
Snow-covered areas have decreased by about 10% over the past 30 years, with the most significant decreases occurring in April and May.
Permafrost temperatures in boreholes within the Arctic Refuge were up to 5°F warmer in than they were in Rising temperatures. According to the Intergovernmental Panel on Climate Change, "warming in the Arctic, as indicated by daily maximum and minimum temperatures, has been as great as in any other part of the world." The period of – was the warmest decade in the Arctic since at least the 17th century, with temperatures 2 °C ( °F) above the – average.
Climate conditions in the Arctic have been undergoing remarkable changes, particularly during the last 20 years.” One of these remarkable changes was observed in the lowest level of Arctic sea ice retreat on record. Sea ice retreat is more complex than ice simply covering less surface area than before.
Average summer temperatures in the Eastern Canadian Arctic during the past years are hotter than they have been in at le years, and possibly as long asyears.
Climate Model Simulations of the Last 1, Years Paleoclimate records of the last 1, years indicate that climate varies naturally due to factors such as solar and volcanic activity. These factors are called "forcings" because they drive or "force" the climate system to change.
These feedbacks make the Arctic particularly sensitive to changes in climate: with degree C ( degrees F) of global warming, one sea-ice-free Arctic summer is.
A high temporal resolution pollen diagram from a lake in the mid-Arctic region of the Boothia Peninsula, Nunavut, Canada, documents the history of the regional vegetation and climate for the past.
For the last three years in Utqiaġvik, Field and the research team at her Silicon Valley nonprofit Ice have been testing an unusual solution to restore Arctic ice. Her novel approach is on. Hattersley-Smith, G.

The phenomenon has spiked the occurrence of freak weather changes and natural calamities and now, we are infact way past the looming threat of climate change and are in the phase called Climate emergency and the Arctic region is feeling the effects of this drastic fluctuations more than any other place on Earth.
In fact, the Arctic is heating up three times faster than other parts of .
