北极造冰北极海冰融化已经成了一个巨大的问题：海冰能反射阳光，有助于寒冷的极地地区维持低温状态；而在温暖的天气下，海冰变少，反射阳光的能力减弱，地球表面吸收了更多来自太阳的热量，变得更温暖，进一步加剧了冰的融化……最终，这一恶性循环导致海平面不断上升。要想从源头上解决这个问题，最好的办法是减少温室气体 ...

Summer sea ice in the Arctic Ocean might be a thing of the past by the 2030s, no matter what we do to curb emissions of the greenhouse gases that cause global warming, an international study ...

The authors then ran the updated models under four potential scenarios for greenhouse gas emissions. Under the best-case scenario, the Arctic would be ice-free most Septembers by 2050.

Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can ... Monitoring an 'anti-greenhouse' gas: Dimethyl sulfide in Arctic air (2023 ...

New research has moved up the time by which the Arctic Ocean is predicted to be free of summer ice. A paper published Tuesday in the journal Nature has concluded that those northern waters could ...

A warmer Arctic will quicken permafrost melt, releasing more greenhouse gases into the atmosphere, accelerating a dangerous feedback loop. The Greenland ice sheet would likely melt more quickly as ...

Nearly all Arctic sea ice could melt by the summer of 2027, scientists warn - For the first time, a group of international scientists used climate models to predict when the Arctic might see its ...

A new study finds that Arctic sea ice could disappear in the summers as early as the 2030s, ... the swiftest efforts to cut greenhouse gas emissions could limit the ice-free period to the month of ...

Earlier research projected it would be virtually ice-free by late in the century if higher greenhouse gas emissions continued unabated. Sea ice affects Arctic communities and wildlife such as ...

The Arctic could be free of sea ice roughly a decade earlier than projected, scientists warn – another clear sign the climate crisis is happening faster than expected as the world continues to ...

Like ice in a drink, Arctic sea ice keeps things cold – until it melts. ... The ultimate solution is, undoubtedly, deep and rapid reductions in greenhouse gas emissions.
