Jan 23, 2020 · Since the 1970s, we have lost 75% of the volume of Arctic summer sea ice. The Arctic affects the jet stream, causing extreme weather all over the world. The Arctic used to be white but now it's turning blue, and absorbing more heat in a feedback loop.

Nov 18, 2019 · A new time-lapse video shows arctic ice melting off the coast of Greenland, with just 5% of the original mass remaining. The oldest and thickest ice has been replaced by thinner ice, which melts more easily. Researchers say climate change is to blame for continued loss.

Sep 3, 2015 · Watching the ice melt more closely won’t make it melt any slower on its own. Cumulative emissions of CO2 are the main culprit driving the melting of Arctic summer sea ice. The only way to help save Arctic ice is to demand action – from yourself, your city, your country and from the companies that make all the goods and services you consume.

May 17, 2017 · The last piece of summer sea-ice in the Arctic is expected to melt away in just 23 years, three decades earlier than previously expected. Scientists now believe that the summer of 2040 will see the end of the frozen north pole after a rapid shrinking of the ice coverage in recent years, according to a report from the Arctic Council .

Aug 28, 2015 · Arctic ice regulates global climate, including the distribution of heat, and patterns of rainfall or snowfall. As climate change progresses and Arctic summer sea ice continues to melt to unprecedented levels, abnormal weather effects will undoubtedly be felt far from the Arctic Circle. And that brings us back to the annual minimum.

Jun 8, 2023 · Predictions of an ice-free Arctic Ocean have a long and complicated history, and the 2030s is sooner than most scientists had thought possible (though it is later than some had wrongly forecast). What we know for sure is the disappearance of sea ice at the top of the world would not only be an emblematic sign of climate breakdown, but it would ...

Nov 3, 2016 · “The older ice was like the insurance policy of the Arctic sea ice pack: as we lose it, the likelihood for a largely ice-free summer in the Arctic increases.” Image: NASA Earlier this year, the National Oceanic and Atmospheric Administration (NOAA) created an animation that also shows the dwindling of the Arctic’s oldest ice.

Aug 22, 2016 · An ice-free central basin of the Arctic will accelerate the pace of global warming, Wadham says. Sea ice reflects more of the sun’s energy back into space than water – about 50% of solar radiation, compared with less than 10%.

Nov 3, 2020 · The lack of sea ice can cause a vicious cycle of more sea ice melt, as there is less ice to reflect the sun's rays and more ocean to absorb it. With the setting of the sun and the onset of polar darkness, the Arctic Ocean would normally be …

Feb 14, 2020 · Abrupt melting of the permafrost layer is leading to erosion, landslides and craters in the Arctic landscape. As the permafrost melts, greenhouse gases are released into the environment. Current climate change forecasts may underestimate the emissions from permafrost because they only take into account gradual thawing of the ice layer.
