Write a short note on global warming.
Answers
Explanation:
Global warming is a steady rise in Earth's surface temperature.[1][2] Temperatures today are about 1 °C (1.8 °F) higher than 150 years ago.[3] Many scientists say that in the next 100–200 years, temperatures might be up to 6 °C (11 °F) higher than they were before the effects of global warming were discovered. Most noticeable changes by this increase in temperature is the melting of ice caps all around the world. Sea level is rising steadily because of continental ice melting into the sea. As a prediction, many cities are soon to be partially submerged in the ocean. Consequently, many part of the world have a major increase in temperature.
Among the Greenhouse gases, the concentration and increase of carbon dioxide in the atmosphere appears to be the main cause of global warming, as predicted by Svante Arrhenius a hundred years ago, confirming the work of Joseph Fourier more than 200 years ago. When people use fossil fuels like coal and oil, this adds carbon dioxide in the air.[4] When people cut down many trees (deforestation), this means less carbon dioxide is taken out of the atmosphere by those plants.
As the Earth's surface temperature becomes hotter the sea level becomes higher. This is partly because water expands when it gets warmer. It is also partly because warm temperatures make glaciers melt. The sea level rise causes coastal areas to flood.[5] Weather patterns, including where and how much rain or snow there is, will change. Deserts will probably increase in size. Colder areas will warm up faster than warm areas. Strong storms may become more likely and farming may not make as much food. These effects will not be the same everywhere. The changes from one area to another are not well known.
People in government and Intergovernmental Panel on Climate Change (IPCC) have talked about global warming. They do not agree on what to do about it. Some things that could reduce warming are to burn less fossil fuels, adapt to any temperature changes, or try to change the Earth to reduce warming. The Kyoto Protocol tries to reduce pollution from the burning of fossil fuels. Most governments have agreed to it. Some people in government think nothing should change. The gas produced by cows digestion also causes global warming, because it contains a greenhouse gas called methane.
