Re: Effects of Greenhouse Effect on Environment
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist. The release of Greenhouse gases and their increasing concentration in the atmosphere are already having an impact on the environment, human health and the economy. These impacts are expected to become more severe, unless concerted efforts to reduce emissions are undertaken. Environmental impacts -Overall average annual temperatures are expected to increase. -Snow, sea ice and glacier coverage will decrease because of higher temperatures, resulting in rising sea levels and increased coastal flooding. Rising temperatures will also thaw permafrost in the Arctic. -Overall precipitation levels are expected to increase across most of the country and during all seasons, except for parts of southern Canada where there are indications of an expected decrease in summer and fall precipitation. -The increase in precipitation is expected to be combined with more frequent heavy precipitation events, resulting in higher risks of flooding. -Heat waves are likely to increase in frequency and severity, resulting in higher risks of forest fires. -Many wildlife species will have difficulty adapting to a warmer climate and will likely be subject to greater stress from diseases and invasive species. Human health impacts -Higher temperatures and more frequent and severe extreme weather events may increase the risk of deaths from dehydration and heat stroke, and of injuries from intense local weather changes. -There may be a greater risk of respiratory and cardiovascular problems and certain types of cancers, as temperatures rise and exacerbate air pollution. -The risk of water-, food-, vector- and rodent-borne diseases may increase. -People living in Canada's northern communities, and vulnerable populations such as children and the elderly, are expected to be the most affected by the changes. Economic impacts -Agriculture, forestry, tourism and recreation may be affected by changing weather patterns. -Human health impacts are expected to place additional economic stress on health and social support systems. -Damage to infrastructure (e.g., roads and bridges) caused by extreme weather events, thawing permafrost and rising sea levels is expected to increase, impacting local populations and resource development.
