This issue is called global warming. Because of the effect worldwide, Canada is due to be influenced. The increase of greenhouse gas emissions is apparent, as further urbanizations and burning of fossil fuel occur. With the warming climate, arctic ecosystems are suffering a loss of ice, and many Arctic ponds are dissipating. In fisheries, as the melting ice will flow into the ocean and seas, the water levels are rising significantly, salt waters are likely to enter fresh water bodies, and change the temperature. This benefit some species of fish, yet forces others to change their range of habitats, or even become extinct. Furthermore, higher demands for health care will be needed, for health issues will derive. The effects of pollution will deteriorate from warmer climates, and more allergies from dust will follow. There will be many changes in various regions due to climate change. With all these changes, Canada has taken measures in response to the warmer temperatures. The most important project is putting effort to reduce greenhouse gas emissions. Introduction Within the last few decades, the problems derived from climate change have been slowly accumulating. Through many scientific data, it is clearly shown that the earth's climate has become warmer. However, over the past two decades, the climate temperature has been increasing at an uncontrollable speed.

In addition, their birthrates are decreasing. This problem has arisen within the last three decades, providing insufficient data to be sure of the decreasing rate, but scientists are certain that at this rate of melting ice, the birthrate and the population of polar bears are due to decline as well. Health issues There are both benefits and negative parts regarding human health due to climate change. Milder winters will reduce seasonal winter-time deaths or influenza. However, the rate of respiratory and cardiovascular illnesses is likely to increase, because of the inclined exposure to outdoor and indoor air pollutants and allergens. Extreme weather, such as floods, droughts and storms bring higher risks of infectious diseases and threats to food supplies. For example, West Nile virus and Lyme disease are most likely spreading in Canada because of global warming. Furthermore, the warmer temperatures will allow mosquitoes to prosper, resulting in unsanitary marsh areas. With higher temperatures, air pollution is deteriorated and usually, leads to urban smog. Many Canadians get allergies from all the dust and pollutants. The Canadian government estimates that around 16,000 premature deaths per year are related to air pollution. From the air quality, people are more vulnerable to heart attacks, strokes, and cancer. Furthermore, chemical and biological contaminants cause intestinal disorders. Through the damage of ultraviolet rays on skin, people are more prone to skin cancer, cataracts, and a disturbed immune function. Through the increasing rate of care needed, demands and pressure on health care services will accumulate. II. Changes in regions due to climate change Pacific Coast Warming temperatures are due to melt more ice, and a rise in sea level occurs. Especially around low-lying coastal lands, such as the Fraser River delta, is likely to be threatened by flooding and erosion. With precipitation increased, landslides are more likely to happen. Warmer river temperatures are due to go up too, leading to increased mortality rates in fish that go up the rivers to spawn, such as the Pacific salmon.

Conclusion

Aside from the aligned vehicle regulations, two countries have established a 'Clean Energy Dialogue,' advancing in clean energy research and development, and building a more efficient electricity system and renewable energy. The government is also approaching the issue by announcing new regulations to reduce greenhouse gases and air pollutant emissions from aviation, marine, and rail transportations. Conclusion The changes in global climate have become a significant concern, and even though Canada is not affected as severely as other parts of the world, it is impacted in several ways. Through the inclination of greenhouse gas emissions, global warming has affected the Arctic ecosystems, fisheries, and polar bears. With the coming of the warmer temperatures, it gives ideal conditions for pine beetles to thrive, causing problems for the forests of British Columbia. Many health issues, such as illnesses caused by pollution, will intensify. Even though both positive and negatives factors have occurred to different regions of Canada, more negative factors are apparent on the whole. Canada has approached these issues as a matter of high priority. The government has taken many steps, making new regulations to reduce pollution, which would lead to a more gradual, and positive shift in climate. Appendix 1. Trends within Earth, including Northern Hemisphere (Canada) show that it is evident that the temperatures have started to increase around the 1900's, where industrialization began to take place regularly. 2. Atmospheric carbon dioxide concentrations, 1010 to 2004 The rise of carbon dioxide in the atmosphere is mainly due to fossil fuel combustion, deforestation, and industrial processes. The concentration of had been fairly constant, until around the 1900's, when industrialization had begun to soar. Greenhouse gas emissions in Canada, 1990 to 2005 and Kyoto Target The amount of greenhouse gas released into the atmosphere has greatly gone up. 3. The average temperature is slowly increasing up along the years. Red dashed linear trend line indicates winter temperatures have warmed over the last 64 years by 2.8 2.8°C. Out of the twenty years listed, 11 were the warmest winters. [Environment Canada] 4. 5.
