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 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 The oldest and thickest ice has been replaced by thinner ice, which melts more easily.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 …

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.

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.

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.

2019年9月27日 · The Arctic is strategically located for global connectivity, and the melting Arctic ice creates new opportunities for the tech industry. The Finnish company Cinia and Russian MegaFon recently agreed to install a fibre optic cable across the Arctic Ocean, which will significantly reduce latency. Other technologies can also benefit from the cold ...

2017年5月11日 · And rather than diseases being released by melting ice, some argue that as Earth warms northern countries will become more susceptible to outbreaks of "southern" diseases like malaria, cholera and dengue fever, as these pathogens thrive at warmer temperatures.

2023年6月8日 · The ice which remains at the end of summer is called multiyear sea ice and is considerably thicker than its seasonal counterpart. It acts as barrier to the transfer of both moisture and heat between the ocean and atmosphere. Over the past 40 years this multiyear sea ice has shrunk from around 7 million sq km to 4 million. That is a loss ...

2023年6月1日 · A new study finds that the Montreal Protocol, an international treaty that aims to protect the ozone layer, has also had the unexpected benefit of slowing Arctic sea ice loss. The Protocol had averted more than half a million square kilometres of Arctic summer sea ice loss by 2020 and is a shining example of what can be achieved when countries work together to address a common challenge.

2020年8月24日 · The Arctic sea ice is melting at a rate far faster than almost all climate models predicted. In fact, only models based on the worst-case scenario come close to what temperature measurements show over the past 40 years. More research is …
