There is of … The ice caps are melting and sea levels are rising. While Antarctica's sea ice is growing somewhat, the Arctic and the world's glaciers are disappearing at … Nov. 25, 2020 — Over the past 40,000 years, ice sheets thousands of kilometers apart have influenced one another through sea level changes, according to new research. Accessed April 7, 2020. Every year, the cap of frozen seawater floating on top of the Arctic Ocean and neighboring seas melts during the spring and summer and grows in the fall and winter. So this "the polar ice caps are melting" nonsense we've been hearing from global alarmists for the past too-many years, has been as true as that time I won World's Strongest Man and turned down Kate Upton's sexual advances. The 1981 to 2010 median is in dark gray. A time-lapse animation has been released by NASA showing how the Arctic sea ice has changed over the past 30 years. Accessed April 7, 2020. The Arctic ocean freezes during winter, reaching a maximum sea ice extent around March. As this water enters the world’s oceans, it can disrupt currents and lead to changes in the climate, as the oceans are the main system that regulates global temperatures. Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map the extent in the late 1970s. The graph above shows Arctic sea ice extent as of January 6, 2020, along with daily ice extent data for four previous years and the record low year. There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase matter in the polar region. Polar climates have an average temperature below 10°C throughout the year. Due to gravity, they flow downhill at varying rates of speed. This yields an areal loss of Antarctic sea ice extents in 4 y exceeding the total loss suffered by the Arctic sea ice cover in the entire 40-y 1979–2018 satellite multichannel passive-microwave record and raises the question of whether the Antarctic sea ice might be more amenable than the Arctic sea ice to very rapid (nonannual-cycle) decreases. Life in the icy Arctic isn't so hard if you're prepared! 2B-1: Tundra is a treeless area with permanently frozen soil (permafrost) and low growing vegetation. NSIDC: 2020 Polar Ice doing just fine. According to the latest October report from the National Snow and Ice Data Center (NSIDC), the ice locked at Earth’s poles is, overall, GROWING. As the average temperatures in the Arctic rise at an increased speed, the threat of the world’s ice sheets melting is becoming a reality. The ice reaches its annual maximum extent sometime between February and April. Climate.gov. These image pairs show the average concentration of Arctic sea ice for the month of September (left) and the following March (right) from September 1990 to March 2020. Updated data from NASA satellite instruments reveal the Earth’s polar ice caps have not receded at all since the satellite instruments began measuring the ice caps in … Of course man-made global warming climate change is fake. Until now, climate models have predicted a slow and steady increase of Arctic temperatures, but a new study shows the warming is occurring at a more … Updated: March 7, 2020. In this Climate Now live we discuss what's really happening to the Arctic, Greenland and Antarctica. Copied. Posted in Uncategorized | 24 Comments. However, the warming atmosphere has the power of making polar regions vulnerable to different changes. These climate types are located at very high latitudes. The two major polar climates are the tundra and ice cap climates. 2019 to 2020 is shown in blue, 2018 to 2019 in green, 2017 to 2018 in orange, 2016 to 2017 in brown, 2015 to 2016 in purple, and 2012 to 2013 in dotted brown. October 24, 2020 October 24, 2020 Cap Allon. The Arctic was supposed to be “ice free” in the summer by [insert year] but 1) ice free isn’t defined, but is some generic alarmist phrase. The West Antarctic ice sheet, the biggest mass of ice in the world, has been growing since the end of the nineteenth century. Arctic Sea Ice News and Analysis, National Snow and Ice Data Center. Polar ice caps are responsible for reflecting a large portion of incoming sunlight back out to space, keeping ocean temperatures regulated. This summer, the ice caps finally met their demise after decades of rising temperatures and unusually warm summers chipped away at the centuries of snow … A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year. Travel to the edge of the Greenland Ice Sheet to find out what could happen if global warming melts it and the West Antarctic Ice Sheet. A polar ice cap is an extensive area of land at the North or South Pole covered with massive amounts of ice. Comparing that to today, where average sea ice in the Arctic is 3.3 feet thick in October but will grow on average 5 feet more of sea ice through the winter. A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice. Although they were abnormally large, the state of the polar ice caps in 1979 became the standard baseline in NASA’s study. Sea ice analysis indicated that during this rather mild winter in the middle latitudes, trapped colder air in the polar circle had a positive impact on the rapid growth and recovery of the polar ice cap, Severe Weather Europe meteorologists said. New modelling of ice … While the sea ice maxima extent date (early March) is surely governed by increasing insolation by early March (and nothing is growing then in the Arctic either), the beginning sea-ice anomaly deviation begins in mid-May that differentiates between a high ice minima year and a low ice minima year. 2) despite 2012 showing a less abundant amount it wasn’t “ice free” by sny measure and subsequent seasons have all been within the standard deviations of the limited baseline period. Polar ice cap climates are frozen throughout the year (Creative Commons: Ronald Woan). Earlier this week, the earth’s northern ice cap also showed the impacts of the climate crisis. Left: Average Arctic sea ice cover for January 2020. So, while the glacier is growing, the ice sheet is still losing tremendous mass and contributing to sea-level rise. She's so aggressive you know. Arctic sea ice reached its annual minimum, at the second lowest extent seen in four decades. Charctic, National Snow and Ice Data Center. Opaque white areas indicate the greatest concentration, and dark blue areas are open water. Giant icebergs are surrounded by ice floe drift in Vincennes Bay, Antarctica. Melting Ice, Rising Seas . Moving ice … However, compared to the January extents of the last decade it was relatively close to average. The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. As the ice melts, the surrounding waters warm up, leading to more melt and so on. Posted on January 29, 2020 by tonyheller. Sea Ice Same Thickness As 60 Years Ago. Marc Morano featured a post about a fascinating Chinese study from Dr. Patrick Michaels at the website of CFACT’s friend and ally the Competitive Enterprise Institute.. Whereas Arctic sea ice mostly sits in the middle of land-locked ocean—which is more sensitive to sunlight and warming air—Antarctic sea ice surrounds land and is constantly exposed to high winds and waves. The average Arctic sea ice extent in January 2020 was 13.5 million km2, that is 0.9 million km2 (or 6%) below the 1981-2010 average for January. Antarctic Ice. Sea Ice Index, National Snow and Ice Data Center. Of course it's been a hoax. (2019, March 12). Let's Talk with David Bromwich about Meteorology in the Poles. Far away in the high arctic polar desert of Ellesmere Island in Nunavut, Canada, next to Greenland, were once the twin St. Patrick Bay ice caps. Three years ago, climate alarmists announced that Arctic sea ice extent had dropped (at -30C) to record low winter levels. 2B-2: Ice sheets and continental glaciers (land ice) are not static. These are the E climates in the Koppen System. Polar Climates. Every summer some sea ice melts — that's normal — but this ye . It's the Arctic's ice cap and it's shrinking. Accessed April 7, 2020. Solve the puzzle of how people and polar bears live in a land of ice. Tuesday, November 24, 2020 Eye on the Arctic. “That’s how the warming of the ocean translates,” Khazendar says. August 2020: Following intense summer heat, Arctic sea ice melts to its second-lowest extent on record, nearly reaching 2012 levels. This suggests something other than insolation or even water temps are at play. The Arctic sea ice is melting faster than climate models had predicted, researchers at the University of Copenhagen warned on August 25. CGTN Share . 2B: Ice shapes the Polar landscape. According to climate models, rising global temperatures should cause sea ice in both regions to shrink. Arctic sea ice growing this winter, but there's more to the story . Antarctica is colder than the Arctic, but it’s still losing ice. Climate 15:00, 26-Aug-2020 Arctic sea ice melting faster than forecast. Posted on January 30, 2020 by tonyheller. However, in NASA satellite images from July 2020, they are nowhere to be seen.
