zika virus, and dengue season may soon arrive further up the Northern hemisphere as conditions become suitable for theAedes aegypti. Melting permafrost may also mean the resurgence of ancient disease-causing bacteria.
The country as a whole has become wetter, while sea levels on the country's coasts rose about 21 centimeters between 1880 and 2012. The impacts are apparent in Canada's north, the report says, where melting permafrost and glaciers are changing the landscape quickly. "Glaciers in Yukon have ...
The article reports that frozen ground forestry, permafrost provided a stable base for roads and homes, but that stability is vanishing. In Yellowknife, Northwest Territories, an insulating liner was needed 4 meters below a 100-meter section of sagging runway. At the Arctic port of Inuvik, ...

Forest cover provided more protection than shrubs or bare ground, and thick layers of peat were such effective insulators that permafrost showed only minimal decline even by 2100. On the other hand, Arain adds, disturbance of the ground cover on a local scale or fires in the boreal forest an...
