The subarctic climate (also called subpolar climate, or boreal climate) is a continental climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50°N to 70°N, poleward of the humid continental climates .
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° and 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America , Europe , and Asia . [ 1 ]
Boreal forests, also known as taiga, are warming at a faster rate than the global average, [14] leading to drier conditions in the Taiga, which leads to a whole host of subsequent impacts. [15] Climate change has a direct impact on the productivity of the boreal forest, as well as its health and regeneration. [15]
Canada’s nearly 700-million-acre boreal forest, which is about 28 percent of the world’s boreal zone, stores carbon, purifies air and water and acts as a climate regulator.
Although temperate and tropical forests in total cover twice as much land as boreal forest, boreal forest contains 20% more carbon than the other two combined. [1] Boreal forests are susceptible to global warming because the ice/snow–albedo feedback is significantly influenced by surface temperature, so fire induced changes in surface albedo and infrared emissivity are more significant than ...
Over the winter, the Porcupine herd travels over 1,500 miles from the boreal forests in Yukon to the coastal plains of Beaufort Sea. ... Climate change also has a significant impact. The ...
Insect outbreaks also represent an increasingly significant threat. Historically, temperatures have been low enough in the wintertime to control insect populations, but under global warming, many insects are surviving and reproducing during the winter months, causing severe damage to forests across the North American boreal.
The boreal forest/taiga supports a relatively small variety of highly specialized and adapted animals, due to the harshness of the climate. Canada's boreal forest includes 85 species of mammals, 130 species of fish, and an estimated 32,000 species of insects. [37] Insects play a critical role as pollinators, decomposers, and as a part of the ...
