2020年1月23日 · 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.

2019年11月18日 · A pattern similar to the Arctic ice melting is seen in the Antarctic, which has lost around a sixth of its ice cover since 2014. The region has lost as much sea ice in the past four years as the Arctic lost in the past 34 years.

2023年6月8日 · 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 ...

2015年9月3日 · 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.

2015年8月28日 · Scientific observations – on land, sea and space – all show that the Arctic summer sea ice is on a long-term downward spiral. While the melt itself is a natural process, the degree to which the summer sea ice disappears is not: with record-high Arctic temperatures over the past few decades, Arctic ice is disappearing fast.

2020年2月13日 · The Arctic circle is about the same geographic size as the African continent─about 6% of Earth’s surface area─yet it holds an estimated 22% of Earth’s oil and natural gas resources. This paints a target on the Arctic for exploration and development, especially with shorter seasons of ice coverage improving ocean access.

Between 2013 and 2023, there was a 37% increase in unique ships entering Arctic waters. The Arctic Council’s Arctic Monitoring and Assessment Programme has found that even a small rise of 1-2% in shipping traffic could lead to a surge in Arctic black carbon emissions occurring right on the edges of increasingly vanishing summer sea ice.

2023年6月1日 · The Protocol has also had the unexpected benefit of slowing Arctic sea ice loss. It has already delayed the first “ice-free” summer in the Arctic by around 15 years. By 2050, it will have averted 0.88C of Arctic warming. For every averted tonne of ozone-depleting substances, around 7,000 square kilometres of Arctic sea ice loss is avoided.

2017年5月17日 · The scientific policy group of the eight countries with territory in the Arctic Circle says that over the past 30 years, the minimum coverage of summer ice has fallen by half while its volume has fallen by three-quarters. This change has profound implications, beyond those countries that have a direct stake in the region.

2016年4月4日 · Researchers have discovered a link between disappearing Arctic sea ice and dogged weather systems that are rapidly melting the surface of Greenland. During Greenland summers, melting Arctic sea ice favors stronger and more frequent “blocking-high” pressure systems, which spin clockwise, stay largely in place, and can block cold, dry ...
