Global Warming Problems, Its causes and effects

linedividerGlobal Warming – a gradual increase in planet-wide temperatures – is now well documented and accepted by scientists as fact. A panel convened by the U.S National Research Council, the nation’s premier science policy body, in June 2006 voiced a “high level of confidence” that Earth is the hottest it has been in at least 400 years, and possibly even the last 2,000 years. Studies indicate that the average global surface temperature has increased by approximately 0.5-1.0°F (0.3-0.6°C) over the last century. This is the largest increase in surface temperature in the last 1,000 years and scientists are predicting an even greater increase over this century. This warming is largely attributed to the increase of greenhouse gases (primarily carbon dioxide and methane) in the Earth’s upper atmosphere caused by human burning of fossil fuels, industrial, farming, and deforestation activities.

The increase in greenhouse gases caused by human activity is often cited as one of the major causes of global warming. These greenhouse gases reabsorb heat reflected from the Earth’s surface, thus trapping the heat in our atmosphere. This natural process is essential for life on Earth because it plays an important role in regulating the Earth’s temperature. However, over the last several hundred years, humans have been artificially increasing the concentration of these gases, mainly carbon dioxide and methane in the Earth’s atmosphere. These gases build up and prevent additional thermal radiation from leaving the Earth, thereby trapping excess heat.

In the future, though, the climate debate will be much more than an energy debate. We would need cleaner power and fuel to cut emissions, but we would also need to use
less power and fuel. That would require changes to our energy-gorging routines, more biking, walking, carpooling, telecommuting and mass transit; smarter growth
patterns; less energy-intensive agriculture; more recycling; less waste. We would need an ecologically sustainable economy, not the current cheap-oil-based one that
Earth Policy Institute President Lester Brown calls the “throwaway economy.”

About Carl William Brown

I'm Carl William Brown a holistic teacher, a webmaster, a trader, and a writer of aphorisms and essays. I have written more than 9,000 original quotations and at present I'm also working at my only novel, Fort Attack, which is also a wide and open blog project. At the moment I'm teaching English in a secondary school, but up to now I have done a lot of other things as well, both in business, educational, sport and social fields. Some years ago, in 1997 following the examples of the Rotary or the Lyons Clubs I founded the Daimon Club Organization to promote every sort of activities, creativity, art, literature, new technologies, informatics, business and marketing, public health and education and to meet new friends with these kind of interests.
