Sure, space may be silent, or at least absent the sound waves that human ears can hear. But put that aside for a moment, and try to imagine the sound of a satellite orbiting hundreds of miles above ...

In the process of researching a feature for the Earth Observatory, I always come across fascinating tidbits that just don’t quite fit into my article. For instance, there’s this great carbon ...

Earth’s climate is determined by a delicate balance between how much of the Sun’s radiative energy is absorbed in the atmosphere and at the surface and how much thermal infrared radiation Earth emits ...

This blog post is the first in a series to come. Our team, the Climate & Ecosystems Change research group from the Vrije Universiteit Amsterdam, is working in collaboration with the Environmental ...

Although the volcanically contaminated CO 2 data are removed from the global averages, they are still scientifically useful. I have published two papers in which I used the non-baseline, volcanically ...

The Fast Carbon Cycle The time it takes carbon to move through the fast carbon cycle is measured in a lifespan. The fast carbon cycle is largely the movement of carbon through life forms on Earth, or ...

Effects of Changing the Carbon Cycle All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the ...

Since its launch in February 2013, Landsat 8 has collected about 400 scenes of the Earth’s surface per day. Each of these scenes covers an area of about 185 by 185 kilometers (115 by 115 miles)—34,200 ...
