Some of these viruses and bacteria may have been trapped for thousands of years, and it’s not even totally clear yet what they are, let alone what kind of damage they might have.Researchers have met complex “giant viruses” in the melting permafrost(永久冻土) of Siberia. One such virus...
the head of the energy program at Greenpeace Russia, in an interview. “All countries in the North feel the consequences of global warming quicker than those in equatorial or tropical regions because their permafrost layers are slowly melting.” ...
Many of the\nexpected changes will be negative; already, permafrost is melting in Siberia, and apartments and factories\nare sinking into quagmires. The melting of Arctic ice, however, will also open sea-lanes to shipping and allow\naccess to enormous oil and gas reserves beneath the Arctic ...
Researchers have met complex “giant viruses” in the melting permafrost(永久冻土) of Siberia. One such virus, 30,000 years old, was still infectious when it was discovered in 2015, though it posed no danger to humans. It turns out that permafrost is excellent at preserving bacteria and ...
Although scientists disagree about the rate at which Arctic ice is melting, climate change will greatly alter the northern latitudes in coming decades if greenhouse gas emissions are not curtailed. Many of the expected changes will be negative; already, permafrost is melting in Siberia, and ...
percent is in the atmosphere.The cycling of water consists of atmospheric water vapor transport and precipitation,surface evaporation,transpiration from vegetation,infiltration of water into the ground,overland runoff and riverflow(河流径流),and water stored in the oceans,snow,glaciers,permafrost,and ...

Mark Smith/University of Leeds Warmer air temperatures have driven ice loss, which has in turn raised land temperatures. That has caused the melting of permafrost, a frozen layer just beneath the Earth’s surface and found in much of the Arctic, and that melt releases ...

” says Rumpf. Warming also causes further melting of glaciers and the thawing of permafrost, which may lead to more landslides, rockfalls, and mudflows. Furthermore, Rumpf emphasizes the important role of snow and ice from the Alps in the supply of drinking water and, not least, for ...
