Global Warming: Are Humans to Blame? Kelly Gaffney October 10‚ 2011 SCI 207 Instructor Reale In order to understand the issue of global warming (also referred to as climate change)‚ you must first understand what it means and how it happens. Global warming is a result of a process known as the greenhouse effect‚ in which the light and heat from the sun are trapped in the Earth’s atmosphere by greenhouse gases; which subsequently raises the average temperature on Earth. The greenhouse

Cause and effect of global warming Global warming occurs when the levels of greenhouse gasses rise and less infrared light‚ or heat‚ escapes the earth ’s atmosphere. Thus‚ the temperature experienced on Earth begins to rise. Climate change is a part of the Earth ’s history. There have been dramatic fluctuations in overall average temperature for the past 150‚000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with

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. Over the last 100 years‚ the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C‚ or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms‚ floods and raging forest fires we

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

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

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
