Definition of Global Warming

Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet habitable. However, by burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising. The vast majority of scientists agree that global warming is real, it’s already happening and that it is the result of our activities and not a natural occurrence.1 The evidence is overwhelming and undeniable. We’re already seeing changes. Glaciers are melting, plants and animals are being forced from their habitat, and the number of severe storms and droughts is increasing.

Cases & Effect


The theory of global warming is both controversial and political. But most of us aren't even sure what it is. Here's your chance to get informed! The atmosphere surrounding the Earth contains something called "greenhouse gases." Certain gases that exist naturally in the atmosphere trap heat that would otherwise escape into space. It's like building a blanket over the Earth. And it's a good thing, too, because otherwise the Earth would be 60 degrees colder than it is now. The problem is human beings are thickening that blanket by adding air pollution to the atmosphere. It's estimated that burning oil and other fossil fuels have pumped over 700 billion tons of carbon dioxide pollution into the atmosphere! And that's what experts reason is causing the Earth to warm—a thicker blanket means a warmer planet.

A Summary Of Inconveniant Truth

Part of the predictions of global warming is harsher weather. While you cannot blame specific weather events on it, you can speculate that if you see an increase in co2, rapid global temperature change, and therefore, temperature differences; the average global storm numbers and intensities especially at unusual times and in unusual places, can rightly be predicted to be an almost direct effect of global warming. Many people try to claim that they are having a snow storm right now, so global warming can't be happening. But to make a snow storm you need a warm front and a cold front colliding. Now, the vast majority of the world heat comes from the equator and is transferred to the north and south through ocean currents and pressure differences. The tendency for particles is to distribute energy equally, so the heated air particles will circulate to the cooler northern areas, and then circulate back down when they are cooler. But now, because the amount of heat coming from the equator is accelerating, you will areas where cold air isn't circulating in the normal fashion, same with warm. Storms are fueled by the differences in heat in the atmospheric particles involved. So when warm air isn't circulating right, you will see huge cold fronts and warm fronts in strange places, and strange times of the year, causing more storms, and greater storm intensity. This is why in Antarctica, where there is virtually no warm fronts, there is less precipitation then anywhere else on earth as Al Gore said" Basically on his Film Algore was trying to get people's attention so0o they all know what's wrong with their earth and also to start thinking for future.... Here's some info from his film

A study of UAE's Scientests about global warming



Some Scientists believe that human beings are not the main cause of global warming. They believe that solar energy releases CO2 more than human beings. According to “The Great Global Warming Swindle” the Professor Ian Clark Said that “ the sun is the single larges reason for global warming and many other factors …”. Some Scientist disagree that human are the main cause of the increases of greenhouse gases are done by human activities. As Ian Clark insists that that the sun increases global warming and that the ice “..core samples from Antarctica shows that warmer period in earth’s history have come about 800 years before rises in carbon dioxide. Another Scientists believe that the real reason of global warming are human beings. According to Martin Durkin “ humans are very likely to be blame for global warming and that there is no doubt that it is caused by man’s use of fossil fuel”. Also, according to the 4th report released in 2007 by UN's Intergovernmental Panel on Climate Change (IPCC), which was compiled by 600 scientists from 40 countries, states that global warming is "unequivocally" happening and that there is a "90% chance that it is caused by human activity."
Human beings are the main reason of global warming and as evidence of that I did a study case on the UAE to see who is responsible of global warming humans or nature. The UAE is classified as one of the most active places in the world, which can be justified by the amount of the investments that take place there.
