"[107], Individual countries within the Arctic zone, Canada, Denmark (Greenland), Finland, Iceland, Norway, Russia, Sweden, and the United States (Alaska) conduct independent research through a variety of organizations and agencies, public and private, such as Russia's Arctic and Antarctic Research Institute. The effects of global warming in the Arctic, or climate change in the Arctic include rising air and water temperatures, loss of sea ice, and melting of the Greenland ice sheet with a related cold temperature anomaly, observed since the 1970s. ", "We found more plant growth in the boreal zone from 1982 to 1992 than from 1992 to 2011, because water limitations were encountered in the later two decades of our study," added co-author Sangram Ganguly of the Bay Area Environmental Research Institute and NASA Ames. This observed pathway suggests that methane from seabed permafrost will progress rather slowly, instead of abrupt changes. [59], It has been estimated that about two-thirds of released carbon escapes to the atmosphere as carbon dioxide, originating primarily from ancient ice deposits along the ~7,000 kilometer long coastline of the East Siberian Arctic Shelf (ESAS) and shallow subsea permafrost. Since 1979, the ice volume has shrunk by 80% and in just the past decade the volume declined by 36% in the autumn and 9% in the winter. Shades of green depict areas where plant productivity and abundance increased; shades of brown show where photosynthetic activity declined. [36], Reliable measurement of sea ice edges began with the satellite era in the late 1970s. This is a particular danger among marine mammals who were previously segregated by sea ice.[79]. A common feature of these models is an effect called polar amplification. Climate Literacy & Energy Awareness Network. In the permafrost there is twice as much carbon as in the atmosphere, but scientists estimate that no more than 100 billion tonnes will be released in the 21th century (humanity emit each year 40 billion). [44][45] In 2012 however, the 2007 record low was broken in late August with three weeks still left in the melt season. But the Arctic is warming at a faster-than-average rate. The thawing of the various types of Arctic permafrost could release large amounts of carbon into the atmosphere. What are the effects of a warming Arctic? Locally, the sea ice season is reduced by up to one month. Some scientists suggest that climate change will slow the jet stream by reducing the difference in temperature between the Arctic and more southern territories, because the Arctic is warming faster. Global warming is causing the entire planet to warm up on average. [101] The harvest of different animals fluctuates each year and with the rise of temperatures it is likely to continue changing and creating issues for Inuit hunters. [53] A summertime ice-free Arctic would be unprecedented in recent geologic history, as currently scientific evidence does not indicate an ice-free polar sea anytime in the last 700,000 years. Extreme weather is another effect of global warming. In contrast to the Northeast Passage (including the Northern Sea Route) and the North-West Passage it largely avoids the territorial waters of Arctic states and lies in international high seas. According to this reconstruction, the Arctic showed a slow cooling trend for … NASA researcher Josefino Comiso points to an accelerating warming trend as a primary cause and discusses how global climate change may be influencing the shrinking Arctic ice cap. [101] The reduction of sea ice will cause certain species populations to decline or even become extinct. There are projections that precipitation might increase by approximately 10-20% and the region covered by snow might reduce by approximately 15-20%. Other effects could take place later this century, if warming continues. A new study used field observations, radiocarbon dating, and remote sensing to account for thermokarst lakes, the authors concluded that, "..methane and carbon dioxide emissions from abrupt thaw beneath thermokarst lakes will more than double radiative forcing from circumpolar permafrost-soil carbon fluxes this century. Our results outline complex links between local climate, vegetation, and ecosystem-atmosphere interactions, with likely local-to-regional impacts on the atmospheric composition. (2007): Record Arctic sea ice minimum confirmed by NSIDC, Intergovernmental Panel on Climate Change, Effects of global warming on marine mammals, Chinese Arctic and Antarctic Administration, National Oceanic and Atmospheric Administration, Climate and vegetation interactions in the Arctic, "From 2 Satellites, the Big Picture on Ice Melt", "Rare Burst of Melting Seen in Greenland Ice Sheet", "Greenland ice sheet melted at unprecedented rate during July", "). [80] What does that mean for the ice, animals,… [35], Sea ice is currently in decline in area, extent, and volume and summertime sea ice may cease to exist sometime during the 21st century. Scientists use the information to calculate the Normalized Difference Vegetation Index (NDVI), an indicator of photosynthetic activity or “greenness” of the landscape. "Satellite data identify areas in the boreal zone that are warmer and drier and other areas that are warmer and wetter," explained co-author Ramakrishna Nemani of NASA's Ames Research Center. Scientist Professional Development Opportunities, Science Communication Workshops for Scientists, Educator Professional Development Programs (2015-2019), Science Investigations (Sci-I) Project Workshop. Much of the climate change in the Arctic can be attributed to humans influences on the atmosphere, such as an increased greenhouse effect caused by the increase in CO2 due to the burning of fossil fuels. Greater vegetation growth also masks snow cover on the ground, further reducing surface reflectivity. The growing season has lengthened in the far northern latitudes, bringing major changes to plant communities in tundra and boreal (also known as taiga) ecosystems. Sea ice serves to stabilise methane deposits on and near the shoreline,[67] preventing the clathrate breaking down and venting into the water column and eventually reaching the atmosphere. For the period 2002–2009, the rate of loss increased from 137 Gt/yr to 286 Gt/yr, with every year seeing on average 30 gigatonnes more mass lost than in the preceding year. The Russian part of the Arctic is the part of the planet with the most dramatic warming. Exact measurements can be made only at a limited number of points. [100] Tourism may also increase as less sea ice will improve safety and accessibility to the Arctic. [38] Some of this variation may be related to effects such as the Arctic oscillation, which may itself be related to global warming. (2009) provided a reconstruction of pan-Arctic temperatures based on various types of proxy information, including lake sediments, pollen records, diatoms and tree rings. [47][48], The rate of the decline in entire Arctic ice coverage is accelerating. The Arctic is a unique ice-dependent ecosystem. Already in the past 30 years, we’ve seen areas of Arctic sea ice melt that are larger than Norway, Sweden and Denmark combined. Many boreal forests greened, but the trend was not as strong as it was for tundra of the circumpolar Arctic. 1b) align with this 35 pattern, with a cooling tendency over the eastern US and especially central Asia, and 36 an accelerated warming of the Arctic compared with that seen in Fig. The researchers concluded that plant growth had increased by 7 to 10 percent overall. By my calculations, the terrestrial warming in the Arctic is roughly equivalent to a 25 percent boost in global CO2 emissions. However, so far neither US or Denmark has taken responsibility for the clean-up. The Transpolar Sea Route is a future Arctic shipping lane running from the Atlantic Ocean to the Pacific Ocean across the center of the Arctic Ocean. [66] This source of methane is different from methane clathrates, but contributes to the overall outcome and feedbacks. The Arctic is warming more quickly than almost any other region on Earth as a result of climate change. [100], The melting of Arctic ice caps is likely to increase traffic in and the commercial viability of the Northern Sea Route. In North America, some boreal forests actually experienced “browning” (less photosynthetic activity) over the study period. Over the last decades, the average temperature has increased by more than five degrees Celcius. The observed changes over recent decades (Fig. Another correspondingly direct effect of global warming is: any change in the polar conditions affects those of all the other regions. According to Russian meteorological service Roshydromet, it is the Kara Sea and nearby areas of Taymyr and Yamal that now is the region with the quickest warming. The melting can also cause leakage of toxic elements from sites of buried toxic waste.[64][65]. However, the effect on marine ecosystems is unclear, since the larger types of phytoplankton, which are the preferred food source of most zooplankton, do not appear to have increased as much as the smaller types. "Warming Greenland ice sheet passes point of no return: Even if the climate cools, study finds, glaciers will continue to shrink. Some 200 Svalbard reindeer were found starved to death in July 2019, apparently due to low precipitation related to climate change. [45] While the Arctic ice area and extent show an accelerating downward trend, arctic ice volume shows an even sharper decline than the ice coverage. [71], The less severe winters in tundra areas allow shrubs such as alders and dwarf birch to replace moss and lichens. They also found that during storms, methane levels in the water column drop dramatically, when wind-driven air-sea gas exchange accelerates the ebullition process into the atmosphere. [99] Climate change is having a direct impact on the people that live in the Arctic, as well as other societies around the world. [97][98], People are affecting the geographic space of the Arctic and the Arctic is affecting the population. [73] The warming is likely to cause changes in the plant communities.

The pollution reached the lake Pyasino that is important to the water supply of the entire Taimyr Peninsula. Indirectly, changing advective processes in the Nordic Seas may further intensify this effect. Being an arctic predator means puts polar bears at a heightened risk of extinction. The new paper helps to show how the Arctic is a connected system affected by global warming, said National Snow and Ice Data Center scientist Twila Moon, who was not involved in … Such effects would be bad enough if confined to the Arctic Circle and above, but what goes on up there really does affect almost every human on the planet.

From sonar measurements in recent years researchers quantified the density of bubbles emanating from the subsea permafrost into the Ocean (a process called ebullition), and found that 100–630 mg methane per square meters is emitted daily along the East Siberian Shelf, into the water column. In the year 2019 the melting contributed 2.2 millimeters to sea level rise in just 2 months. The rivers Ambarnaya, Daldykan and many smaller rivers were polluted.

Once the polar ice melts, this flushes more freshwater from the region's rivers, consequently holding the ocean from circulating fast enough, thereby causing higher sea levels. Subsea permafrost occurs beneath the seabed and exists in the continental shelves of the polar regions. The climate change in the Arctic is also affecting the quality and characteristics of snow which is used to build shelters such as igloos. 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. But, what has happened as air temperatures have warmed over time? [61][62], As of 2018, modeling of the permafrost carbon feedback has focused on gradual surface thawing, models have yet to account for deeper soil layers. Access to natural resources will increase, including valuable minerals and offshore oil and gas. [58], The heat wave leaded to increase in the number of Siberian silk moths that damaged trees what help increase wildfires. CDOM drives a significant part of these changes, suggesting that an increase of this material will amplify the observed Arctic surface warming through its direct thermal effect. [100] Finding and controlling these resources will be difficult with the continually moving ice. © 2020 Polar Literacy @ Rutgers University -, PhenoCam Teacher Workshop – Using webcam data to explore climate change – Thursday 10/15/20. Arctic marine mammals have adapted to the extreme and seasonally varying Arctic environment, becoming highly specialized at using different habitats for reproduction, foraging, molting, and migration in different seasons (Kovacs and Lydersen 2008, Gilg et al. Both direct and indirect effects result in large geographic differences in VOC emission responses in the warming Arctic, depending on the local vegetation cover and the climate dynamics. It is unclear whether the appropriate pre-conditions for such an event exist today. But, what has happened as air temperatures have warmed over time? In the face of ongoing global warming, the poles are warming faster than lower latitudes. [72] The feedback effect of shrubs on the tundra's permafrost is unclear. [21] Such heat waves are generally a result of an unusual state of the jet stream. These are comparable to the September to September loss rates in year-round ice (i.e., perennial ice, which survives throughout the year), which averaged a retreat of 10.2% and 11.4% per decade, respectively, for the period 1979–2007. Before this time, sea ice area and extent were monitored less precisely by a combination of ships, buoys and aircraft. 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. However, boreal forests, particularly those in North America, showed a different response to warming. This is because the movement of ice from the middle of Greenland to the coast creates a larger contact between the ice and the warm water that leads to more melting and calving. Sea ice area refers to the total area covered by ice, whereas sea ice extent is the area of ocean with at least 15% sea ice, while the volume is the total amount of ice in the Arctic. The route is also sometimes called Trans-Arctic Route. [85] It is also predicted that Greenland will become warm enough by 2100 to begin an almost complete melt during the next 1,000 years or more. Why the Arctic Is Warming So Fast, and Why That’s So Alarming When permafrost thaws, sea ice disappears, and wildfires rage in the north, the consequences extend to the rest of the world. [100] The changing landscape and unpredictability of weather is creating new challenges in the Arctic. Some atmospheric scientists have argued that such cold events may be associated with the rapid warming of the Arctic that has been observed over recent decades and that is manifested in the … This warming is not only restricted to the land but can also be noted in the Southern Ocean. Global warming's ripple effects are creating never-before-seen changes in the Arctic's biophysical system and beyond, according to a new study released today. [42][43], From 2008 to 2011, Arctic sea ice minimum extent was higher than 2007, but it did not return to the levels of previous years. Changes in vegetation are associated with the increases in landscape scale methane emissions. It is the strongest link of a weather event to anthropogenic climate change that had been ever found, for now. For decades, NASA and NOAA satellites have continuously monitored vegetation from space. [39], The Arctic sea ice September minimum extent (i.e., area with at least 15% sea ice coverage) reached new record lows in 2002, 2005, 2007, and 2012. 1a. While there are several factors at work, the main reason for this is “ice-albedo feedback.” Ice is highly reflective (it has a high "albedo") and … Arctic warming can also affect the jet stream, a fast west-to-east flow of air that hovers high in the troposphere, by weakening it and causing it to meander. [102], researchers have documented historical and current trails created by the Inuit in the Pan Inuit Trails Atlas, finding that the change in sea ice formation and breakup has resulted in changes to the routes of trails created by the Inuit.[103]. Since their tradition, culture, and knowledges are all developed within their ecosystems, the rapid climate change in Arctic affect the indigenous people living in Arctic requiring them to change such as identity and diet. [86][87] In early July 2012, 97% percent of the ice sheet experienced some form of surface melt, including the summits. [76], The reduction of sea ice has boosted the productivity of phytoplankton by about twenty percent over the past thirty years. [40] The 2007 melt season let to a minimum 39% below the 1979–2000 average, and for the first time in human memory, the fabled Northwest Passage opened completely. [78], The increase of heat waves causes an increase in wildfires. [46] It continued to fall, bottoming out on 16 September 2012 at 3.41 million square kilometers (1.32 million square miles), or 760,000 square kilometers (293,000 square miles) below the previous low set on 18 September 2007 and 50% below the 1979–2000 average. One of the better known: the continually shrinking summer sea-ice extent in the Arctic… Recent years have seen a series of unusually cold winters in northern mid-latitudes, including the eastern United States, where they have been accompanied by extremely heavy snowfalls. Hunting, which is a major way of survival for some small communities, will be changed with increasing temperatures. [100], Other forms of transportation in the Arctic have seen negative impacts from the current warming, with some transportation routes and pipelines on land being disrupted by the melting of ice. Motivation: Why a Polar Literacy Initiative? [1][2][3] Related impacts include ocean circulation changes, increased input of freshwater,[4][5] and ocean acidification. Recent years have seen a series of unusually cold winters in northern mid-latitudes, including the eastern United States, where they have been accompanied by extremely heavy snowfalls. The Arctic influences global climate through three major feedback mechanisms, all of ... 3.3.3 Currently, the direct effect of the Arctic Ocean on the level of CO 2 in the atmosphere is limited. [9] Presently, the Arctic is warming twice as fast as the rest of the world. Why the Arctic Matters for Global Warming. [82] Secondary ecological effects are also resultant from the shrinkage of sea ice; for example, polar bears are denied their historic length of seal hunting season due to late formation and early thaw of pack ice. [23], The poles of the Earth are more sensitive to any change in the planet's climate than the rest of the planet. The United States's National Oceanic and Atmospheric Administration (NOAA) produces an Arctic Report Card annually, containing peer-reviewed information on recent observations of environmental conditions in the Arctic relative to historical records.[108][109]. [84], Models predict a sea-level contribution of about 5 centimetres (2 in) from melting of the Greenland ice sheet during the 21st century. Because of large variations in ice and snow thickness and consistency air- and spaceborne-measurements have to be evaluated carefully. [77] In summer, the melt ponds on young and thin ice have allowed sunlight to penetrate the ice, in turn allowing phytoplankton to bloom in unexpected concentrations, although it is unknown just how long this phenomenon has been occurring. [106] Shipping companies may benefit from the shortened distance of these northern routes. [96] At the Arctic Ocean Conference, Foreign Ministers and other officials representing the five countries announced the Ilulissat Declaration on 28 May 2008. [95], Danish Foreign Minister Per Stig Møller and Greenland's Premier Hans Enoksen invited foreign ministers from Canada, Norway, Russia and the United States to Ilulissat, Greenland, for a summit in May 2008 to discuss how to divide borders in the changing Arctic region, and a discussion on more cooperation against climate change affecting the Arctic. Many buildings and infrastructure are built on permafrost, which cover 65% of Russian territory, and all those can be damaged as it melts. This kind of weather was expected in the region only by 2100. In 2019 - 2020 the wildfires in Peatlands release more carbon to the atmosphere in 18 months than in the previous 16 years. [14] Some regions within the Arctic have warmed even more rapidly, with Alaska and western Canada's temperature rising by 3 to 4 °C (5.40 to 7.20 °F). Although this is now thought unlikely in the near future, it has also been suggested that there could be a shutdown of thermohaline circulation, similar to that which is believed to have driven the Younger Dryas, an abrupt climate change event. [69], Changes in vegetation are associated with the increases in landscape scale methane emissions.[70]. Potential methane releases from the region, especially through the thawing of permafrost and methane clathrates, may occur. In March, April and May the average temperature in the Arctic was 10 °C higher than normal. So far, Arctic phytoplankton have not had a significant impact on the global carbon cycle. The Arctic region is one of the territories that have experienced the full hit of Global warming and because of the importance that the area has to the rest of the planet, the effects of a warming Arctic are manifested through severe environmental changes occurring around the globe. "[17][18], On 20 June 2020, for the first time, a temperature measurement was made inside the Arctic Circle of 38 °C, more than 100 °F. The Arctic is a unique ice-dependent ecosystem. The collective results reported in the 2018 Arctic Report Card show that the effects of persistent Arctic warming continue to mount. How will Arctic warming affect the rest of the planet? Since cushion plants act as facilitator species across trophic level and fill important roles in severe environments this could cause cascading effects in the ecosystems. [88], Ice thickness measurements from the GRACE satellite indicate that ice mass loss is accelerating. They rely on the other arctic animals as food sources, but these animals are also being harmed by the uptick in global temperatures. [93], According to a study published in "Nature Communications Earth and Environment" the Greenland ice sheet is possibly past the point of no return, meaning that even if the rise in temperature were to completely stop and even if the climate were to become a little colder the melting would continue. Climate Time Machine Travel through Earth's recent climate history and see how increasing carbon dioxide, global temperature and sea ice have changed over time. During the course of global warming, the energy balance and thus the temperature of the earth change, due to the increased concentration of greenhouse gases, which has a significant impact on humans and the environment. The melting of permafrost caused a collapse of a fuel tank, spilling 6,000 tonnes of diesel into the land, 15,000 into the water. International cooperative research between nations has become increasingly important: The effects of global warming in the Arctic.
