Essay on The Effects of Global Warming

Global warming is a disease caused by greenhouse gases and human activities. Increases in greenhouse gas concentrations caused by activities such as deforestation and burning fossil fuels caused heating of the Earth's atmosphere and oceans. As a result, global warming had a serious impact on abnormal weather, species extinction and sea level rise. These effects can lead to changes taking place all over the world, and most of it will be dangerous enough to pose a threat to the future life on the planet.
Among all the effects of global warming, extreme weather occurring all over the world is the most obvious. Global warming will bring more heat waves, droughts ... See more
A particularly good example is a polar bear whose life is being threatened because the ice that they need to catch and eat is melting. The main eating habits of polar bears are seals, which depend entirely on ice, but as ice melts, habitat will decrease, so polar bears can not be caught safely and there is a possibility of extinction. Many species will no longer be able to withstand heat and will be extinct as the temperature rises. Alternatively, its life cycle is affected by global warming. In addition, rising water temperatures can threaten seeds that are extremely sensitive to temperature changes such as coral reefs. In general, seeds that are biased towards cold regions because of the high temperatures tend to be extinct, as they are difficult to adapt to the new climate, but species that prefer warm regions continue to grow. As more and more species move to different habitats and the overall balance of the ecosystem is greatly disturbed, global warming is said to be a serious threat to biodiversity (Lovgren).
When the earth warms up, as the temperature rises, the polar pole glands break and melt, the sea level rises. "This will bring about the most severe climate change and habitat change"
The impact of global warming on the oceans provides information on the various effects of global warming on the ocean. Global warming affects sea surface, coastline, ocean acidification, ocean current, sea surface temperature, tide, ocean floor, weather, and can cause changes in marine biogeochemistry, all of which affect social activities I will. An agreement in many studies on coastal tidal measure shows that the world sea level is rising at an average rate of 1 to 2 mm / year over the past century. Corresponding studies based on satellite altimeters showed that this rate increased to nearly 3 mm / year during a more complete surveillance over the past 20 years. According to recent literature review, 30% of sea level rise since 1993 is due to thermal expansion, 55% is due to melting of continental ice, both due to the global temperature rise.
As global warming melts the vast polar ice of the Arctic and Antarctic, the sea level is now an average of one foot per century. Due to the greenhouse effect and the loss of stratospheric ozone, the speed of global warming may have risen recently. Many clues about this interesting puzzle, the time and place of the first living in America, are now underwater without a doubt. During the late Ice Age event of Wisconsin, the majority of the Earth's water supply was trapped in huge ice, the sea level fell 280 to 350 feet below today's level, and previously landed a large area of land I exposed it. As a result, we have a continuous crossover between Siberia and Alaska. Most archaeologists believe that human beings first flowed from Asia to the Beringland Bridge in America (also known as the Bering Strait).
