Definition For Global Warming
According to wikipedia.org, the definition for global warming is the following: "Global warming refers to the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last 100 years." All of the national academies of science of the major industrialized countries confirm that global warming is caused by human activities, the so called greenhouse effect to be more exact. The greenhouse effect is produced by the high concentration of greenhouse gases such as carbon dioxide and methane. When the sun rays bounce off from the Earth's surface, those greenhouse gases prevent them from dissipating into space, instead, they get trapped in, which results in temperature increase in the lower layers of the atmosphere.
But according to a small group of scientists, the melting of the ice caps, which is believed to be caused by global warming, is due to an increase of the temperature of the Earth's core. Or in other words, the global warming has nothing to do with all the climate change taking place at present days, and all the extreme weather that are constantly witnessing around the world. Lately, we have witnessed a lot of devastating hurricanes. And let's not forget Katrina. Here is an article from The Boston Globe, issued August 30, 2005: "THE HURRICANE that struck Louisiana yesterday was nicknamed Katrina by the National Weather Service. Its real name is global warming. When the year began with a two-foot snowfall in Los Angeles, the cause was global warming. When 124-mile-an-hour winds shut down nuclear plants in Scandinavia and cut power to hundreds of thousands of people in Ireland and the United Kingdom, the driver was global warming. When a severe drought in the Midwest dropped water levels in the Missouri River to their lowest on record earlier this summer, the reason was global warming. In July, when the worst drought on record triggered wildfires in Spain and Portugal and left water levels in France at their lowest in 30 years, the explanation was global warming. When a lethal heat wave in Arizona kept temperatures above 110 degrees and killed more than 20 people in one week, the culprit was global warming. And when the Indian city of Bombay (Mumbai) received 37 inches of rain in one day -- killing 1,000 people and disrupting the lives of 20 million others -- the villain was global warming." That's the definition for global warming. How can this be explained in scientific terms? We already pointed out there is an increased temperature in the atmosphere, which generates longer droughts followed by more intense rainfall, because the high temperature speeds up the water evaporation process. Global warming causes more-intense downpours, more-frequent heat waves, and more-severe storms. Basically, more extreme weather is to be expected. |
