havent really seen any threads around here for a while about this but....
I just watched an hour long documentary about this, its a very scary subject. They were saying how the polar ice caps melt and im gonna try to break it down as best i can....what happens is the sunlight gets reflected back into the atmosphere because the ice is so white. Since the ocean is dark (and heat is attracted to darker colors), the light gets absorbed by the dark ocean, which warms the temperature and causes ice to melt. Not only that, but the Co2 in our atmosphere also gets absorbed by the ocean and warms it up. Not only does it warm it up, but makes it more acidic, causing major destruction to the ecosystem (coral, plankton, and other sea ceatures)...
I'm curious what everybody's views are about this. Do you do anything to cut down on the amount of electricity or greenhouse gasses you use? Personally, i would ride a bike to work everyday if it was feasible but i work too far away from where i live...i try not to use drive thru anything, i try not to leave lights on for no reason and i use energy efficient light bulbs, and i use dimmer switches...
if everybody (not only simple civilians but governments and big business especially) practices simple ideas like these, we wont have to worry so much about Global Warming...I think we need leadership from Governments in the form of support, public ads and regulations; and maybe also by producing more fuel-efficient vehicles (i know imports are starting to) from the big companies such as Ford and GM, Dahmler-Chrysler......basically, less talk and more action...
some quick facts from the documentary:
-With a 5 metre rise in the atlantic ocean, Florida would be almost completely engulfed, and the skyscrapers of Miami would be 50 miles from the coastline of the USA..
-With a 5 metre rise in the Indian Ocean, Bangladesh (home to 120 million people) would be completely wiped off the face of the earth..
facts from websites:
(http://news.nationalgeographic.com/news/2004/12/1206_041206_global_warming.html)
-The spring ice thaw in the Northern Hemisphere occurs 9 days earlier than it did 150 years ago, and the fall freeze now typically starts 10 days later
-The 1990s was the warmest decade since the mid-1800s, when record-keeping started. The hottest years recorded: 1997, 1998, 2001, 2002, and 2003
-The multinational Arctic Climate Impact Assessment (ACIA) report recently concluded that in Alaska, western Canada, and eastern Russia, average temperatures have increased as much as 4 to 7 degrees Fahrenheit (3 to 4 degrees Celsius) in the past 50 years. The rise is nearly twice the global average. In Barrow, Alaska (the U.S.'s northernmost city) average temperatures are up over 4 degrees Fahrenheit (2.5 to 3 degrees Celsius) in 30 years
-The United Nations' Intergovernmental Panel on Climate Change (IPCC) projects that global temperatures will rise an additional 3 to10 degrees Fahrenheit (1.6 to 5.5 degrees Celsius) by century's end.
-Rising temperatures have a dramatic impact on Arctic ice, which serves as a kind of "air conditioner" at the top of the world. Since 1978 Arctic sea ice area has shrunk by some 9 percent per decade, and thinned as well.
-Over the very long term, Greenland's massive ice sheet holds enough melt water to raise sea level by about 23 feet (about 7 meters). ACIA climate models project significant melting of the sheet throughout the 21st century.
-Studies show that many European plants now flower a week earlier than they did in the 1950s and also lose their leaves 5 days later.

-Motor vehicles (cars, trucks, buses, and scooters) account for 80% of all transport-related energy use
-The global fleet of motor vehicles has been recently growing at the rate of 16,000,000 per year.
-The global fleet of motor vehicles is estimated at 830,000,000 (2006).
-The concentration of carbon dioxide has increased an average of about 1.8 ppm per year over the past two decades
-About 75% of the annual increase in atmospheric carbon dioxide is due to the burning of fossil fuels. The remaining 25% is attributed to anthropogenic changes in land use, which have the effect of reducing the net uptake of carbon dioxide. Anthropogenic changes in land use occur when forests are converted to rangelands, rangelands to agriculture, and agriculture to urban areas
