I want a speech on the topic "Global Warming" for ASL...

Carbon dioxide in the environment due to rising levels of global warming of the earth's surface temperature to rise continuously. It is a big and serious issue for the global community is becoming. All countries of the world community needed positive steps for its solution. Many dangers of rising global temperatures regularly rise to the existence of life on this planet that will make it harder. Regular and permanent changes in the Earth's climate will increase and it will worsen the balance of nature.
Lots of global warming is due to greenhouse gas primarily because of natural processes, some of which were created by humans. Population explosion, the economy and energy use in the 20th century because of greenhouse gases has been increasing. Many greenhouse gases emitted into the atmosphere is the cause of industrial actions as necessary to meet almost every need of industrialization in the modern world.
Over the years Carbon dioxide (CO2) and Sulphur dioxide (SO2) 10 times increased. Oxidation recycling and natural and industrial processes including photosynthesis varies according to the exit Carbon dioxide. Methane in the atmosphere called the decomposition of organic stuff! Greenhouse gas emissions. Another greenhouse gas, nitrogen oxide, bromine, carbons, CFCs and chlorine compound etc.. They get together in the environment and the environment of radioactive equilibrium is upset.
Antarctica decline in the ozone layer is also a cause of global warming. Increased gas CFCs in the ozone layer is declining. The cause of global warming is anthropogenic. CFCs also a gas pollutant used in many places like industrial cleaning liquid in the refrigerator, which is known to increase the regular reduction in the ozone layer.
Assignment Earth's ozone layer is protected from the harmful rays. While the Earth's surface move indicating that global warming is occurring in the ozone layer depletion. Harmful ultraviolet rays from sun enters the biosphere and greenhouse gases is absorbed by him which ultimately is the increase in global warming. If you look at the statistics it is estimated that one who casts Antarctica (25 million kilometers) of the double hole in the ozone layer hole. In winter and summer ozone depletion is not any significant trend.
Global warming means increased over the years due to the impact has been very clear. According to the US geological survey, Montana, Glacier National Park had 150 glaciers, but now only 25 are left, due to its impact. Major climate change and powerful storms is becoming more dangerous. Energy from the temperature difference is the natural storms are much more powerful. Since 1895 to 2012 as the warmest year recorded since 1880 and 2003, with 2013 as the warmest year recorded.
While many climate change due to global warming, such as increases in the summer season, a reduction in cold weather, the increase in temperature, change in the form of air-rotation, the jet stream, unseasonal rains, melting snow peaks, ozone corrosion layer, severe storms, tornadoes, floods, droughts.
