Global Warming: News, Facts, Causes & Effects

Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. There is great debate among many people, and sometimes in the news, on whether global warming is real (some call it a hoax). But climate scientists looking at the data and facts agree the planet is warming. While many view the effects of global warming to be more substantial and more rapidly occurring than others do, the scientific consensus on climatic changes related to global warming is that the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years. The increased volumes of carbon dioxide and other greenhouse gases released by the burning of fossil fuels, land clearing, agriculture, and other human activities, are believed to be the primary sources of the global warming that has occurred over the past 50 years. Scientists from the Intergovernmental Panel on Climate carrying out global warming research have recently predicted that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100. Changes resulting from global warming may include rising sea levels due to the melting of the polar ice caps, as well as an increase in occurrence and severity of storms and other severe weather events.

Answer 2

Climate Change

- by Taylor

Human activities which have a significant impact on the climate are the burning of fossil fuels such as coal, oil and gas, whether in homes, factories, vehicles or in other ways.

Burning fuels releases carbon dioxide gas, a greenhouse gas, besides others. Since the early 1800s, when people began burning large amounts of coal and oil, the amount of carbon dioxide in the earth's atmosphere has increased by nearly 30%, and average global temperature appears to have rice and over by 1°C.

Such a temperature rise will cause changes in the amount and pattern of rain and snow, in the length of the growing seasons, in the frequency and severity of storms, and in the sea level. Farms, forests, plants and animals would also be affected. Humans also cannot escape the effects of this and hence should do their bit to save the environment.
