Consider it a duel among doomsayers.
In Alberta political circles, Lorne Taylor is sometimes referred to as the "egghead redneck." It is a mark of the man that Taylor, who is Alberta's environment minister and who holds a Ph.D. in educational psychology, takes more umbrage at the first half of that moniker than the latter.
Standing in the back of the room, Louise Comeau didn't even attempt to hide her anger.
Acid rain is the wet or dry deposition of acidic substances and their precursors on the Earth's surface. The ongoing industrialization of society has resulted in the increased release of acidic chemicals into the atmosphere.
Humidity is related to the amount of moisture or water vapour in the air. Although invisible, water vapour is always present in the atmosphere.
Weather forms the Canadian psyche as much as hockey and the maple leaf.
For example, in British Columbia, the Coastal Western Hemlock Zone is one of 14 biogeoclimatic zones. It occupies high precipitation areas up to 1000 m elevation west of the coastal mountains from the Washington to Alaska borders and beyond.
In Canada the official national meteorological service definition of a blizzard is a period of 6 or more hours with winds above 40 km/h, with visibility reduced to below 1 km by blowing or drifting snow, and with windchills over 1600 W/ m2 (watts per square metre).
Floods are primarily caused by naturally occurring changes in the height of rivers, lakes and oceans. According to Public Safety Canada, floods are the most common natural hazard in the country and among the costliest. Historic floods have occurred across Canada, with many of the worst happening on major river systems that pass through populated areas. Scientists predict that flooding linked to the impacts of climate change will increase as the 21st century progresses, particularly in coastal areas of the country.
During the prolonged darkness of winter, the air over the huge snow- and ice-covered surfaces of Canada may stagnate for weeks, radiating heat to outer space.
There are six time zones in Canada covering four and a half hours. From west to east these time zones are: Pacific, Mountain, Central, Eastern, Atlantic and Newfoundland. From the first Sunday in November to the second Sunday in March these zones are referred to as standard time zones, and may be abbreviated as PST, MST, CST, etc. From the second Sunday in March to the first Sunday in November most of Canada follows daylight saving time. During this summer period the time zones may be abbreviated as PDT, MDT, CDT, etc. The boundaries of the standard time zones are not necessarily the same as those of the corresponding daylight saving time zones. For example, the Mountain time zone includes a portion of northeastern British Columbia in the summer, but not during the winter (see maps below). Boundaries shift because some municipalities choose not to participate in daylight saving time. Similarly, Saskatchewan follows CST year-round.
Climate change occurs when long-term weather patterns begin to shift. These periods of change have occurred throughout the Earth’s history over extended periods of time. However, since the Industrial Revolution the world has been warming at an unprecedented rate. Because of this, the current period of climate change is often referred to as “global warming.” Human activities that release heat-trapping greenhouse gases, such as the burning of fossil fuels, are largely responsible for this increased rate of change. 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.
In Canada, the chinook belt lies almost exclusively within southern and central Alberta. The wind occurs in every season, but it is more distinctive and numerous in the winter, when the unseasonable warming it brings differentiates it from the normal cold winter weather.
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 100, with a score of 1 representing the least severe climate and 100 the most.
Climate is often defined as average weather, when weather means the current state of the atmosphere. For scientists, climates are the result of exchanges of heat and moisture at the Earth's surface. Because of its size, Canada has many different climates.
Cloud, visible suspension in the atmosphere composed of tiny water droplets or ICE crystals from about one to a few hundred micrometres in diameter.
Albertas energy minister, Steve West, spent much of last week wearing a tight smile, his clenched jaw and square shoulders set as firmly as his conviction that people who blame the oilpatch for the next centurys foul weather have lost their heads.
