Climate change and its environmental and economic effects

Climate changes effects badly in all organisms (people, animals and plants), also its effects on the agriculture, social and economic planning. As the statistic say that there is a strong link between the increasing in the temperature and the Diseases, therefore 30% of the new diseases emerged in the last 30 years. Another significant effect is the bad effect on the agriculture. The scientists say that there is particularly or completely decrease in global food production. Another important effect for the climate change is the sea level which will rise noticeably by the melting ice which will raise the ocean level with the time.

Global warming effects

There are several effects of global warming. The most important point is the climate changes, as the scientist noticed that the temperature raised10 degree over the last century. Another significant effect is the melting of the polar ice caps which raise the sea levels and could cause flooding and lots of major crisis. Increased spread of infectious diseases may be one of the major effects of the global warming. According to the world health organization the global warming contributes about 150,000 deaths. Degraded water quality, altered patterns of agriculture, and extreme weather events all these may be under the effect of the global warming.One of the biggest effects is the atmospheric pollution; the human activities are increasing the amount of carbon dioxide and other greenhouse gases in the atmosphere. This is causing more of the sun’s heat to be trapped, thus causing the intensification of the air pollution which can make the global warming problem too great.

Burning fossil fuels

We all know that the level of CO₂ in the atmosphere used to be balanced between the CO₂released by respiration and absorbed by plants. The scientist noticed that the amount of releasing CO₂has been increased than the amount of absorbing. The main reason of having a lot of CO₂in the atmosphere is burning the fossil fuels by cars and power station. Yet another reason for more CO₂in the atmosphere is removing trees that use CO₂for photosynthesis. All these things make air pollution which seems to be the worst cause of global warming and climate changes.

The fossil fuels burning releases the carbon in the fuel as CO₂, which putting more in the atmosphere to trap more heat. Also, the fossil fuels release two other harmful gases such as the sulphur dioxide and also various nitrogen oxides. All these gases when mix with the clouds they form acid rain. So, the dangers of global warming begin to knock and the hazards of these gases are great and great.

Global warming causes

Global warming is cause by several things. The scientists decided to divide them to two major groups. The first one is the natural causes, and the second one is the man- made or human activities. The natural causes split to five factors, one important one is the Explosion on the sun which means that the sun gives off more heat than the sun normally, and the earth temperature will increase. Another point under the natural causes is the changes in earth orbit, the scientists observed that any small changes in the earth place could cause the earth to move closer to the sun; therefore the temperature will increase too. Yet other significant points are the volcanoes eruptions on a massive scale and the changes in earth’s orientation toward the sun. Most statistic and graphs shows that the human activities are a major cause of global warming. The worst activity is the fossil fuels burning, which increase the atmospheric carbon dioxide, also earth the industries and most agriculture practices which changing the climate. The human activities also include the deforestation and reforestation.
