Greenhouse gases to be better measured - KTKA.com

With temperatures this cold, its hard to believe that climate scientists still argue that Earth is warming too fast, and they say a lot of it is because of this--carbon dioxide. Scientists say there is too much carbon dioxide in the atmosphere.

In the past, scientists heavily relied on satellites to measure greenhouse gases. Now, scientists are banding together, all over the world, to get the best measurement of carbon dioxide. The mission has them very excited.

"The things that excite me about this project; it's the first time we've been able to look, in great detail, at the whole globe, all at once," said Steven Wofsy.

They will be flying all over the globe, at different heights in the sky, for the next five years.

"When we finish up, we'll have a completely new picture about how greenhouse gases are entering the atmosphere, and being removed by the atmosphere; both, by natural processes and humans," said Wofsy.

From there scientists gain better insight into the future of our climate than ever before.

Global Climate Change and Its [Alleged] Impact on Minnesota - Minnesota Pollution Control Agency

While some scientists may disagree about the causes and extent of global climate change, few doubt that the Earth's climate is warming. Some University of Minnesota researchers predict that if trends continue, Minnesota could look a lot like Nebraska in the coming years.

During the last century, the average temperature in Minneapolis, Minnesota, has increased slightly from 43.9°F (1888-1917 average) to 44.9°F (1963-1992 average), and precipitation in some areas of the state has increased by up to 20%, especially in the southern half.

During the next century, Minnesota's climate may change even more. According to an international scientific body known as the Intergovernmental Panel on Climate Change, the earth's average temperatures will rise between two and 10 degrees Fahrenheit by the year 2100, with northern latitudes like Minnesota at the upper end of the range.

In addition, carbon dioxide, the principal greenhouse gas, persists in the atmosphere for hundreds of years. So once global warming begins, its effects will continue for hundreds of years, too.
