Global warming a steady increase in the average temperature of the world's atmosphere and its oceans, this rise is believed to be permanently changing the world’s weather. While a lot of people see the effects of global warming to be more significant and more rapidly happening than others do, the scientist agree on the fact that climatic variations has risen temperature of the Earth between 0.4 and 0.8 °C in past hundred years.

The bigger volumes of CO2 and other gases produced by the burning of fuels and other human activities are thought to be the main sources of the global warming that has happened over the past 50 years. Weather experts from the Intergovernmental Panel on Climate conducted global warming research have just forecast that global temperatures on average could increase in-between 1.4 and 5.8 centigrade in year 2100.

Greenhouse gases keep the earth’s surface warm making it habitable for human beings and animals. On the other hand, global warming is occurring mainly to an over production of these gases. In the beginning of industrial revolutions in the 1700s, people started emitting more gases by burning of oil, coal, and gas to run our trucks, cars, and factories. There is more CO2 in the atmosphere today than at any point in the last 800,000 years.
In the last century, ocean’s surface levels rose approximately 7 inches after not having changed prominently in the previous 2,000 years. Rising in the Sea levels are an effect of global warming and put many nations at risk of existing in the near future. Costs of global warming include hurricanes, massive fires, drought and melting of the polar caps. Heat waves produced by global warming present much bigger risk of heat-related illness death and illness, most...
