Canada's annual average temperature over land has warmed by 1.7 °C (3.1 °F), with changes ranging from 1.1 to 2.3 °C (2.0 to 4.1 °F) in various regions, since 1948. [4] The rate of warming has been higher across the North and in the Prairies. [4] In the southern regions of Canada, air pollution from both Canada and the United States ...
Southern Manitoba has a fairly long frost-free season, consisting of between 120 and 140 days in the Red River Valley. It is also prone to high humidity in the summer months with the extreme of 53.0 °C (127.4 °F) in Carman, which set the highest humidex recorded in Canada. There are three main climatic regions.
Some wetlands are a significant source of methane emissions [6] [7] and some are also emitters of nitrous oxide. [8] [9] Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Wetlands can also act as a sink for greenhouse ...
The Canadian boreal forest is a very large bio-region that extends in length from the Yukon-Alaska border right across the country to Newfoundland and Labrador. It is over 1,000 kilometres (620 mi) in width (north to south) separating the arctic tundra region from the various landscapes of southern Canada. The taiga growth (as defined in North ...
Meanwhile, a wide range in annual temperature might suggest the opposite. We could also derive information about a site's ecological conditions through a climograph. For example, if precipitation is consistently low year-round, we might suggest the location reflects a desert; if there is a noticeable seasonal pattern to the precipitation, we ...
The mean annual temperatures range from 0.5 to 2.5 °C (32.9 to 36.5 °F), with summers ranging 13 to 16 °C (55 to 61 °F), and winters ranging −14.5 to −12.5 °C (5.9 to 9.5 °F). The Peace River Country in northwestern Alberta and northeastern areas of the North Interior in British Columbia has the coolest climate, but still supports ...
The city has a humid continental climate with wide temperature contrasts between winter and summer, and greater precipitation in summer. Mean January temperature is −16.4 °C (2.5 °F), and mean July temperature is 19.7 °C (67.5 °F). Average annual precipitation is 521.1 mm (20.52 in); snow falls on 53 days and lies on 132 days in an ...
A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season".
