the years? “Global warming” refers to the global-average temperature increase that has been observed over the last one hundred years or more. But to many people‚ the term carries that mankind is responsible for that warming. Global warming is a man made problem that has been progressing over the years and is getting worse and worse. Believe it or not‚ very little research has ever been funded to search for natural mechanisms of warming…it has simply been assumed that global warming is man made

Global warming is the observed increase in the average temperature of the Earth’s atmosphere and oceans. Higher temperatures threaten dangerous consequences: drought‚ disease‚ floods‚ and lost ecosystems. From sweltering heat to rising seas‚ global warming’s effects have already begun. Many people still believe that since the earth is so big‚ human beings cannot possibly have any major impact on the way the planet operates. The truth is we have grown so numerous and our technologies have become so

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‚

Global Warming: The Greatest Hoax Since Pope John VIII Some Americans may wonder why global warming has become so prevalent in the media in the past few years. Global warming is one of the most controversial issues to ever be discussed. The issue‚ which should be based completely on scientific evidence‚ is being used in the media as propaganda in order to falsely sway the public’s opinion about the issue. Positions on the issue taken by members of the Republican and Democratic Party are worlds

Billy Joel once said‚ “we didn’t start the fire”. He is right; global warming is a natural cause. The Earth was heating long before humans were emitting large amounts of greenhouse gases and even before humans were on planet Earth. Since humans were not alive during the period after the ice age (known as the post-ice age era)‚ then the heating of the Earth to melt the ice does not put humans at fault. Global warming is naturally caused by natural emission of greenhouse gases‚ Earth’s heating and

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

Are Humans Responsible for Global Warming? A REVIEW OF THE FACTS APRIL 2007 AUTHORS James Wang‚ Ph.D. Bill Chameides‚ Ph.D. Are Humans Responsible for Global Warming? The case for attributing the recent global warming to human activities rests on the following undisputed scientific facts: • Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times‚ atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm.

Greenhouse Effect and Global Warming Today‚ at the down of 21st century‚ together with the 20th century‚ especially the second half‚ is the time when Earth’s environment change at the very rapid rate. Humans have lived on this planet for thousands of years. I think now is the time to think how do we impact the place where we live‚ and the only place where we can live. The impact of human race on the natural processes of our planet has now reached the levels that are now global‚ not local anymore
