Global warming is being caused by humans, not the sun. What is global warming? Carbon dioxide and other air pollution that is collecting in the atmosphere like a thickening blanket, trapping the sun's heat and causing the planet to warm up. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution -- they produce 2.5 billion tons every year. Automobiles, the second largest source, create nearly 1.5 billion tons of CO2 annually. The planet is changing faster than expected, with the earth getting hotter, and coal-burning power plants are to blame for the largest amount of carbon dioxide pollution. Coal-burning power plants are the largest U.S. source of carbon dioxide pollution. So you might wonder, what is…show more content…
Technologies such as solar power, wind, bioenergy and more can change the ways that energy is being produced and prevent the dangers of global warming. Scientist have figured out the most rapid problem, is that the ocean currents carry heat around the globe. Many problems result from global warming. One of the biggest problems is how much rise in sea level there has been. The rise in seal level could result in the flooding of low costal areas and cities. Ice on Greenland and along Antarctica is disappearing too. Climate models did not predict the shrinking of the sea ice in the Artic Ocean in in more recent years. Attempting to figure out what was happening, scientists have been charting, by satellite and ground measurement, glaciers in Greenland. They also have been sending probes under the Antarctic ice shelves. A Glaciologist in Greenland watched a lake of melt water get drained through a crack, 3000 foot thick, ice. It was powerful enough to lift the massive glacier off the bedrock and slide it into the ocean at a very fast speed. The data shows that the huge glaciers slide into the sea has increased from one meter a day to about 15 to 20 meters a day. Along the coasts of Antarctica and Greenland, large ice shelves are collapsing, showing how unstable they really are. The ice shelves act as supporters, as they hold back the ice that is grounded on the ocean floor and glaciers
