Globalwarming


Now a day a lot of the challenges are facing the planet such as earthquakes, volcanoes and environmental crises. The major crisis is global warming. Scientists called the increasing of earth’s temperatures Abnormally Global warming. Global warming is an increase in the average temperature of Earth's surface. This climate change threatens human life, animal and life in the sea. Here I’m going to write some causes, solutions and effectives of global warming.
In last three decade earth’s average temperature has increased about 0.7 to 1.4 degrees F ,Scientists estimate that the average temperature will rise an additional 2.5 to 10.4 degrees F by 2100(Michael D.Mastrandrea,B.S.Nasa ) There are several problems of this increase in temperature. Melting of icebergs float could increase the sea level Which leads to cover coastal cities such as Florida ,India and Bangladesh and this will force people to leave their homes also animals would be affected. Furthermore Swedish chemist suggest that the burning of fusel fuels such as coil, oil and gasoline which called hydrocarbon might have series impact on the earth temperature because of a huge quantities of carbon dioxide(Ed.Kimberley .A ). Another problem is that topical diseases will spread in the area mosquito and insect will transfer malaria and dengue to large regions. Another problem is that temperature weather will increase, as result of that human will live a difficult life, also the surface waters of the oceans become warmer and this may affect coral reefs and algae which feed.
Experience has shown that there are a lot of solutions of global warming, and there are Individual solutions and collective solutions. And the main solutions are reducing CO2 emission in the atmosphere. CO2 can be cut by finding alterative energy instate of electricity which produced by burning fossil fuels, and the renewable can be solar energy and hydropower. Other solutions An additions solutions is that families can help To preserve the climate, by unplug extra machines like refrigerator and freezer you rarely use. (Ten Personal Solutions to Global warming). An additions Government should put streak roles to avoid exhausted gases from factories.

All and all, our consumption habits can make a huge difference. Much of our global warming problem comes from burning fossil fuels, especially gasoline for cars. Our dependence on them is massive and increased greenhouse gases and the greenhouse effect is feared to contribute to an overall warming of the Earth’s climate, leading to a global warming. Taken as a whole, we have to act together to solve this global crisis which is caused by greenhouse gases, carbon dioxide and ice melts.
