Question

I need an essay on Global Warming and climate change.

Answer 1

Global warming, also referred to as climate change, is the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.[1][2] Multiple lines of scientific evidence show that the climate system is warming.[3][4][5] Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid-19th century, and in paleoclimate proxy records covering thousands of years.[6]

Future climate change and associated impacts will differ from region to region.[13][14] Anticipated effectsinclude increasing global temperatures, rising sea levels, changing precipitation, and expansion of deserts in the subtropics.[15] Warming is expected to be greater over land than over the oceans and greatest in the Arctic, with the continuing retreat of glaciers, permafrost and sea ice. Other likely changes include more frequent extreme weather events such as heat waves, droughts, heavy rainfall with floodsand heavy snowfall;[16] ocean acidification; and species extinctions due to shifting temperature regimes. Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels.[17][18] Because the climate system has a large "inertia" and greenhouse gases will remain in the atmosphere for a long time, many of these effects will persist for not only decades or centuries, but for tens of thousands of years to come.[19]

Answer 2

There are many reasons of climate change including natural cycles of earth however the major contributors of the climate change is global warming. Many human activities and technological development in the world are forcing the greenhouse gases to increase and getting collected to the atmosphere which in turn makes the earth surrounding hot and warm by increasing the temperature of the environment in fast and easy way. Other climate change like rise sea level causes flood which gives rise to malaria and other parasites, increasing coastal erosion, destroying people’s homes in coastal states and so many.

Higher temperature causes problems to the existence of life on this planet even many important species of the plants and animals have been endangered. Longer and severe heat waves of the environment cause more heat-related injuries and higher atmospheric temperature increase rate of water evaporation from smaller water bodies. The ever rising temperature has different effects in different regions like in some areas it raise water levels and in some areas it decrease water levels. Freshwater availability is declining all over the world which is a vital resource of life on this planet. In such a hot environment, it is very hard to grow some crops like corn production may reduced by 10 to 30% if the temperature rises by 3.6 degree Fahrenheit.
