Global Warming

There is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree Fahrenheit (0.6 of a degree

celsius). The warmest since the mid 1800’s was the 1990s. The hottest years recorded were 1997, 1998, 2001, 2002, 2003.

全球变暖

毫无疑问，地球正在变暖。在过去的世纪里，行星温度上升了大约华氏1度（摄氏0.6度的一个）。 1800年中期以来的最热烈的是20世纪90年代。记录的最热的年份是1997，1998，2001，2002，2003。

The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City. 联合国关于气候变化项目小组指出，全球气温将上升3-9度，由本世纪结束飞轮海 - 足有极地的所有，但融化。如果冰盖融化，对我们国家的边境绝大多数会被水淹没。纪念碑和伟大的建筑，以及家庭和生活将被水淹没，包括纽约市。

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is

difficult to connect particular events to global warming. Although most studies focus o

在全球气温上升反过来又会导致其他变化，包括海平面上升和降水量和格局的变化。这些变化可能会增加极端天气事件，如洪水，干旱，热浪，飓风和龙卷风，频率和强度。其他后果，包括更高或更低的农业产量，冰川退缩，夏季streamflows减少，物种灭绝和病媒范围增加。气候变暖影响，预计这些事件的数量和大小，但它很难连接特定的事件对全球变暖。虽然莫

由于气候变化的“主因”是全球化石燃料使用的猛增，因此作为目前世界上最大的二氧化碳排放国的中美两国必须通过开发和利用新技术，大规模推广新能源，才能使两国的能源供给呈现出多样化、可靠、独立和“绿色环保”的特质。Due to climate change \"main reason\" is the surge in global fossil fuel use, so as the world's largest emitter of carbon dioxide in the two countries must be through the development and use of new technologies, large-scale promotion of new energy sources, can the two countries showing a diversity of energy supply, reliable, independent and \"green\" qualities.

Canada's climate is not as cold all year around as some may believe. In winter, temperatures fall below freezing point throughout most of Canada.

催生世界超级大国的四个因素：气候变化;人口增长及人口老化产生的世界范围影响;日渐萎缩自然资源和不断上涨的需求;全球化及全球经济一体化。他预测，中国将在2050年超过美国，成为世界头号超级大国，美国退居第二，印度则紧随其后成为世界第三超级大国。

超级大都市将在2050年遍布世界各地，潮湿的地区会更潮湿，干旱地区会更干旱。地球将会变得更热，在本世纪末，全球气温平均升高摄氏15度。全球的动物为了生存，不得不往北迁徙。

加拿大有地理、政治、社会等多方面的优势，所以能够很好度过这些难关。加拿大吸纳技术移民的政策会凸显优势，尽管加拿大面临人口老化，但凭籍其移民政策，在今后40年里人口有望增长30%。

加拿大等北极周边地区国家从气候暖化中获益，这些仅是全世界范围的小亮点，并不值得全人类共同庆贺。在世界大部分地区遭遇气候暖化的负面影响的境况下，全球民众及政府要更多考虑如何应对和如何改变人类的行为方式，以遏制气候暖化带给人类毁灭性的后果。

随着全球气候变暖，加拿大凭籍着充足的淡水、人口的持续增长、对北方地区的不断开发、用有北极航道等诸多优势，至2050年时有望成为世界超级大国。

地球暖化为北方地区的石油、天然气、淡水等资源的开发，创造了更为便利的条件。靠近北极地区的气候变暖，以往的无法在室外作业的摄氏零下40度的严寒天气就会越来越少。加拿大会吸引移民前往北方地区，随即推动北方地区的基础设施建设及其他项目的开发;而与此同时，其他气候较为炎热的地区，却会面临人口减少及资源枯竭的窘境。

虽然加拿大、俄国、美国北部和北欧斯堪的纳维亚国家(Scandinavian countries)可以从地球气候变暖中获益，但是世界其他地区的民众却要遭受灾难性的损失。

1、气候变得更暖和，冰川消融，海平面将升高，引起海岸滩涂湿地、红树林和珊瑚礁

等生态群丧失，海岸侵蚀全球变暖的可怕后果，海水入侵沿海地下淡水层，沿海土地盐渍化等，从而造成海岸、河口、海湾自然生态环境失衡，给海岸带生态环境系统带来灾难。

2、水域面积增大。水分蒸发也更多了，雨季延长,水灾正变得越来越频繁。遭受洪水泛滥的机会增大、遭受风暴影响的程度和严重性加大，水库大坝寿命缩短。

3、水温升高可能会给南极半岛和北冰洋的冰雪融化。北极熊和海象将灭绝。

4、许多小岛将无影无踪；将感染疟疾等传染病……

5、因为还有热力惯性的作用，现有的温室气体还将继续影响我们的生活。

Birth of the world's superpower four factors: climate change; population growth and aging of the population of the world produced; shrinking natural resources and rising demand; globalization and global economic integration. He predicted that by 2050 China will surpass the U.S. as the world's number one superpower, the United States retreated to the second, followed by India as the world's third superpower.

Super metropolis will be all over the world in 2050, wet areas will be more humid, more arid arid areas. Earth will become hotter, in this century, average global temperature 15 degrees Celsius. The world of animals to survive, had to move north.

Canada has a geographical, political, social, and many other advantages, it can

very well through these difficult times. Canada's policy to attract skilled immigrants will highlight the advantages, while Canada faces an aging population, but by virtue of its immigration policy, the population in the next 40 years is expected to grow 30%.

Canada and other Arctic countries surrounding areas to benefit from climate warming, these are only a small bright spots around the world, mankind is not worth celebrating. In most parts of the world suffered the negative effects of global warming situation, the global public and government should give more consideration to how to deal with and how to change human behavior, to curb global warming devastating consequences for the human race.

With global warming, Canada, by virtue of the abundance of water, the population continues to grow, continue to develop the northern region, with a Arctic waterways, and many other advantages, to 2050 is expected to become the world's superpower.

Global warming into the northern region of the oil, gas, water and other resource development, and create a more convenient conditions. Near the Arctic warming, past the outdoor operations can not be minus 40 degrees Celsius cold weather will be less and less. Canada to attract immigrants to the northern region, immediately north of the region to promote infrastructure construction and other project development; while at the same time, other areas where the climate is hot, but will face population decline and resource depletion dilemma.

While Canada, Russia, North America and Northern Europe the Scandinavian countries (Scandinavian countries) can benefit from global warming, but the rest of the world's population would suffer catastrophic losses.

1, the climate becomes warmer, glaciers melting, sea levels will rise, causing coastal wetlands, mangroves and coral reefs, loss of ecological groups, coastal erosion, the terrible consequences of global warming, sea water intrusion of fresh groundwater level along the coast, coastal land salinization, resulting in the coast, estuaries, bays natural environment balance, to the coastal ecological system disaster.

2, the water area increased. Too much evaporation, prolonged rainy season, floods are becoming more frequent. Chance of flooding being increased, subject to the extent and severity of storms increased dam shortened life expectancy.

3, the water temperature could have on the Antarctic Peninsula and the Arctic Ocean ice melt. Polar bears and walruses will be extinct.

4, many small islands to trace; to malaria and other infectious diseases ... ...

5, as well as the role of thermal inertia, the existing greenhouse gases will continue to affect our lives.
