The plan for a network of Arctic weather bases was approved by the US on 12 February , and on 28 January Cabinet formally agreed to participate. Between and , five sites were selected and built jointly by Canada and the US at Eureka, Isachsen, Mould Bay, Resolute and Alert to provide the data required for the understanding and prediction of meteorological phenomena on a hemispheric scale and, more specifically, to improve weather predictions for North America. The meteorological data collected is also used by forecasting offices, airlines, northern shipping, climatology studies and research.
Strategic environmental assessment is the environmental assessment of policy, plan and program initiatives and their alternatives. It occupies high precipitation areas up to m elevation west of the coastal mountains from the Washington to Alaska borders and beyond. The World Network of Biosphere Reserves includes sites around the world, 18 of which are in Canada. Climate change occurs when long-term weather patterns begin to shift. However, since the Industrial Revolution the world has been warming at an unprecedented rate. The implications of this global increase in temperature are potentially disastrous and include extreme weather events, rising sea levels and loss of habitat for plants, animals and humans.
In Canada, efforts to mitigate climate change include phasing-out coal-fired power plants in Ontario and instituting a carbon tax in British Columbia. The more pronounced the air movement wind or moving air produced by walking, skiing or riding in a convertible and the greater the temperature difference between the surface of the object and the air, the greater the heat loss. To the uninitiated, it looks no more exciting than a long, thin log of grey plasticene.
But to scientists like Jeffrey Fox, a Texas geologist who oversaw its extraction last week from the bottom of a deep bay 16 km north of Victoria, the 9.
Environment Canada devised the climate severity index to rate a locality's climate according to human comfort and well being. The index has a range from 1 to , with a score of 1 representing the least severe climate and the most. Climate information is used by a variety of people.
Building designers must be certain that their structures will withstand the strongest winds and be habitable during temperature extremes. Airlines, when possible, plan their routes to take advantage of the prevailing winds in the upper atmosphere. Both land surface and air are altered by urbanization. Buildings change the geometric arrangement of the land surface, creating a rigid, rough system of blocks and street "canyons," especially in the centre of cities. The study of modern climatology is primarily global in perspective. Across the Arctic, the ominous signs are everywhere. Scientists report a dramatic thinning of the Polar ice cap.
Today's greenhouse industry uses the most modern technologies, which allow it to reduce their negative effects on the environment, to considerably improve the energetic efficiency of crops used energy by unit production and thus to remain competitive in national and international markets. From the outside there was little to distinguish the sleek Toyota Prius from any other car on the streets of Timmins, Ont.
But when the driver turned the key, it was clear this was no ordinary sedan. The only sound as the Prius pulled away was the gentle hum of an electric motor. Most modern meteorologists attempt to cope with physical processes by expressing them mathematically, ie, by creating mathematical models of the atmosphere. Powerful computers are then used to solve problems.
Pollution Probe was formed in by a group of University of Toronto students in an effort to address some of the environmental issues that were without a champion at the time. The organization became a registered charity in Search The Canadian Encyclopedia.
