2] Many chemical compounds found in the Earth’s atmosphere act as “greenhouse gases.” These gases allow sunlight to enter the atmosphere freely. When sunlight strikes the Earth’s surface‚ some of it is reflected back towards space as infrared radiation (heat). Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere. Over time‚ the amount of energy sent from the sun to the Earth’s surface should be about the same as the amount of energy radiated back into space‚ leaving

Global warming is result of greenhouse gases in the atmosphere. These gases trap radiation from sun and hold them from being released back into space. This causes rise in temperature at few places on earth. It is not much noticeable in western part of earth but in eastern parts like North Pole‚ Alaska and others slight increase in temperatures makes a huge difference. Scientists believe that if current situation continues many kinds of changes will take place which can be either beneficial or harmful

The current cycle of global warming is changing the rhythms of climate that all living things have come to rely upon. What will we do to slow this warming? How will we cope with the changes we’ve already set into motion? While we struggle to figure it all out‚ the face of the Earth as we know it—coasts‚ forests‚ farms‚ and snowcapped mountains—hangs in the balance. Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans‚

Many people believe that trying to fix global warming is a hopeless task‚ however global warming can be halted and could even be reversed. This is a very daunting challenge because it means that people have to change the way they live and do things. We could all choose to ignore this situation but the future impact on our planet is huge. Global warming not only brings about climate changes but also will reduce the level of breathable air (O2) and reduce the levels of drinkable water on our planet

Global warming to some individuals is something fake that others say. However‚ global warming is a threat to us. Most people think of this as a scientific fantasy‚ but it can be a huge danger for later generations. We can’t be egocentric and only think about us. Global warming isn’t only effecting us‚ but it’s also effecting animals. Some species might even go extinct because of global warming. We need to do something to prevent or at best slow the process down a bit. I believe it’s vital that we

Head: Global Warming Global Warming APA Research Hessa AlShaikh General Idea about Global Warming Global warming is the increase in average temperature of the oceans and atmosphere‚ both observed and predicted. The surface temperature of Earth depends on a balance of incoming and outgoing heat. When outgoing heat‚ or energy‚ exceeds incoming energy‚ an ice age occurs. Global warming

Some say that global warming will hurt many people‚ animals‚ and plants. Many cannot take the change‚ so they die. Today‚ there is a general debate on the truth of global warming. Some people claim that this is true while there are a number of doubters. Before addressing my opinion‚ I think it is important to look at the argument on both sides. Ben Bova‚ a prolific science fiction author who used to work for NASA‚ claims that global warming is a real phenomenon. According to some measurable scientific

all of the phony science‚ could it be that man-made global warming is the greatest hoax ever perpetrated on the American people? It sure sounds like it‚” said James M. Inhofe a member of the U.S. Senate. Could this be the true? Many facts behind the controversial issue of global warming prove this statement to correct. Global warming is not caused by human activities. Global warming cannot be completely caused by human’s emission of greenhouse gasses.” In the last 1.6 million years there have been

Air Conditioning and Global Warming Air conditioning systems use energy to remove heat from a given location‚ transferring it to the exterior in the form of exhaust. Some of the energy is invariably wasted as heat‚ and this additional heat must also be exhausted. Thus‚ air conditioning results in net heat release to the environment. The warming effect is aggravated‚ moreover‚ because higher forms of energy such as electricity are used to power air conditioners. Generating and transmitting this

detrimental depletion of our world’s reserves of nonrenewable resources‚ we find our world now under a disease called global warming. This chronic warming of our entire atmosphere is leading to catastrophic and disastrous events that prove to be the single most largest issue of our world in known and written history. Scientists‚ according to Livescience magazine‚ say that global warming is the rapid increase in the surface temperature
