It was said that the Earth is so big that you can not do significant damage, but not anymore. What is the most vulnerable part of the ecological system? › ATMOSPHERE So thin is its composition that we can change it. This is the basis of global warming.
The Suns radiation comes in waves of light that warms the Earth. Some of the radiation that is absorbed and warms the Earth back into space as infrared radiation. Part of this radiation that comes out is trapped by the atmosphere and retained.
What this does is keep the temperature and that the Earth is safe to stay alive, and thats good. The trouble is that by becoming thicker atmosphere, all the contamination of human beings, more infrared radiation is trapped and heats the atmosphere around the world.
Roger Revelle, was among the first people who set out to measure carbon dioxide in the atmosphere. After 7.8 and 9 years of studies could look at the pattern that was developing in up and down every year. Why go up and down every year?
If you see the planets land mass is mostly in the north of Ecuador as well as most of the vegetation. When the Northern Hemisphere is tilted toward the sun, in spring and summer, leaves and breathe out carbon dioxide. This causes the amount in the atmosphere decreases.
What happens when the northern hemisphere is tilted away from the sun? As the leaves fall and emit carbon dioxide. As a result, the amount in the atmosphere rises. Carbon dioxide was first measured from 1958 to today.
1000 year to 2005 carbon dioxide has increased by over 40%. Global warming has increased over 80%. When there is more carbon dioxide the temperature is warmer. If we travel back 650.000 years we see that there are 7 ice ages the carbon dioxide has never gone from 300 parts per million. Today is beyond the natural.
If the ocean temperature rises, storms get stronger. Such as: › Frances › Jeanne › Ivan › Tornadoes › Emily › Dennis › Katrina
See that hot pink on the map above? That color is new. While March was warmer than average but not as much as, for example, 2010 or many of the months in 2010 (which broke numerous records), the Arctic (where the most warming has been predicted by climatologists) did see some pretty tremendously warm temperatures (relatively speaking). As a result, climatologists had to add that hot pink color.
EarthquakeGeological changes relatedto climate canalso cause "eruptions ofmethane," the release of apotent greenhouse gas, currently stored in solid formunder the seabed and layersof permafrost are melting, inamounts greater than thewhole carbon dioxide (CO2)from the air today.
Broke off several pieces of glacier ice Sulzberger, who according to historical records had not suffered any break in at least 46 years.
