With temperautres 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.

Now imagine the steam from this bucket of hot water as heat rising from Earth, and this black notebook as greenhouse gases. As the heat rises, some of the steam is blocked by the notebook, and sent back to the bucket--like heat being sent back to the surface of the earth. The additional heat alarms some scientists, who say we are warming up.

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.

"This will allow us to make better predictions of carbon dioxide concentrations in the future, which will allow us to better plan ways to deal with global climate change," said Britt Stephens.
