Global Warming Essay - Part 14

Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation - Global Warming Essay introduction. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward. These basic conclusions have been endorsed by at least 30 scientific society and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with some of the main conclusions of the IPCC, the overwhelming majority of scientists working on climate change are in agreement with them. Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C during the 21st century. The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans. Increasing global temperatures will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yield, trade routes, glacier retreats, species extinctions and increases in the ranges of disease vectors. Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. There is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to it’s.

We don’t agree on everything, but the world does seem to agree on one thing : Global warming is happening, and it’s causing big problems - Global Warming Essay introduction. Global warming refers to the increase in the temperature of the Earth’s atmosphere and it’s oceans. A change that is believed to be permanently changing the Earth’s climate. Scientists have spent decades figuring out what is causing global warming and what is its effects. Global warming is a major problem in the world that should everyone know its causes and effects.

The biggest cause of global warming is carbon in the form of carbon dioxide produced by burning coal and oil. The atmosphere has a natural supply of carbon dioxide and other gases. These gases capture heat and create warming effect on the surface of the Earth. This warming effect is similar to warming inside a green house ,so it become known as the “greenhouse effect”. As a consequence of the Increased emission of these gases the Earth would not be warm enough for us to live on.

One of the causes for global warming is land clearing. Land clearing is the development of land with potential for agricultural use. Land clearing requires the removal of native cover, including trees, bushes and boulders from land surface. The land must then be broken in order to get a workable seedbed into which a crop can be seeded. Land breaking includes the removal of roots, sumps and rocks. Land clearing leads to lack of oxygen and increase of carbon dioxide which is the main reason behind global warming .

People in temperate zones may benefit from milder winters and expanding crop production while people in other areas will suffer from increased heat waves ,coastal erosion, rising sea levels, and droughts. The products that sustain people (food) may be unable to adapt to local or regional climate changes. Temperature also invites a larger range for diseases to expand into. Moreover, Intensified heat waves or rising sea levels affects the livelihood of millions by altering the norms of their constructed culture.

In addition, Heavy rains will change crop seasons and therefore change shipping routes and market prices. Global warming is a dilemma that threatens our life on the Earth. Global warming has many causes, but the two main reasons behind it are land clearing and carbon emissions. Everyone need to be aware of global warming effects. Therefore, they can prevent or even minimize this phenomenon. In short, knowing the causes and effects of global warming is important to face and solve this problem.
