Reflecting its global scope‚ evidence of the Little Ice Age appears in the Southern Hemisphere as well. Sediment cores from Lake Malawi in southern Africa show colder weather from 1570 to 1820. A 3‚000 year temperature reconstruction based on varying rates of stalagmite growth in a cave in South Africa also indicates a colder period from 1500 to 1800. A 1997 study comparing West Antarctic ice cores with the results of the Greenland Ice Sheet Project Two (GISP2) indicate a global Little Ice Age affecting

Global Warming The U.S. Environmental Protection Agency definition of global warming: “Global warming is an average increase in the temperature of the atmosphere near the Earth’s surface and in the troposphere‚ which can contribute to changes in global climate patterns. Global warming can occur from a variety of causes‚ both natural and human induced. In common usage‚ “global warming” often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human

Is Global Warming a Conspiracy? Global warming is the rise in the average temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century‚ Earth’s mean surface temperature has increased by about 0.8 °C‚ with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal‚ and scientists are more than 90% certain that it is primarily caused by increasing concentrations of greenhouse

What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter‚ disasters like hurricanes‚ droughts and floods are getting more frequent The average facade temperature of the globe has augmented more than 1 degree Fahrenheit since 1900 and the speed of warming has been almost three folds the century long average since 1970. This increase in earth’s average temperature is called Global warming. More or less all specialists

Effects of global warming. Global warming refers to the rise in the average temperature of oceans and Earth’s atmosphere since the 19th century and its continuation till today (Wikipedia‚ 2012). Since the 20th century‚ the earth’s surface’s temperature has increased 0.8°C (Wikipedia‚ 2012). The increase seems diminutive‚ but such unsubstantial change has exerted a devastating influence on the whole planet. The environment‚ the people and animals on earth have all suffered from global warming.

Science‚ global warming is 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 forever. The scientific consensus on climatic changes to global warming is that the average temperature of the Earth has risen between 0.4 Cto 0.8 C over the past 100 years (as cited in Live Science‚ n.d.). In the article from the American Policy Roundtable Arguments against Global Warming‚

The causes of global warming is what most people would be shocked about and some of the causes are being used almost every day. One cause of global warming is carbon dioxide being admitted into the air by the burning of fossil fuels. Two things that emit this is factories and cars. One used to meet the demand of buyers and the other used daily by millions around the world. A second

Global Warming and its Effects What is global warming? Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. Many cannot take the change‚ so they die. However‚ global warming has its causes and it also has its effects on humans‚ and animals.
