Play the interactive game metropolis to find the 10 biggest cities in the world based on their carbon dioxide concentrations in the atmosphere above them.
Different materials absorb and reflect different amounts of energy. A dark rock will quickly absorb and not reflect much light energy where as ice will reflect a lot of light and not absorb very much. Man made materials versus natural materials have different absorptions and reflections as well.
Ice is naturally reflective along with certain types of clouds. Rock and other dark materials absorb more energy than lighter materials. Rough materials absorb more energy than smooth materials. This lesson has students collect data on differing materials
James Hansen heads NASA's Goddard Institute for Space Studies in New York. A physicist and astronomer by training, he began his career studying the clouds on Venus. Since the late 1970s he has been studying and modelling the human impact on Earth's climate, and has published more than 100 papers. He entered the public spotlight in the 1980s with his outspoken testimony to congressional committees on climate change. Last year he made headlines when he spoke out against attempts by the US administration to gag climate scientists.
The ozone hole over Antarctica does more than let a little extra ultraviolet light reach ground level: It boosts ocean acidification in the waters surrounding the icy continent and reduces the amount of carbon dioxide emissions those waters can absorb.
Residents of Louisiana, take note: If engineers don’t divert sediment-rich waters from the Mississippi River to help replenish a sinking river delta, about 10 percent of your state will slip beneath the waves by the end of this century. However, even if the engineers do try to abate the subsidence, the Mississippi doesn’t carry enough sediment to offset more than a small fraction of that loss, a new analysis suggests.

This Section surveys one general but vital idea and then addresses how the Earth Sciences community is responding to implementing the outgrowths of this idea. A new field seems to have emerged in the last 20 years. It goes by the imposing name: Earth System(s) Science. But, its ingredients have been around for a long time (some of the components make up the contents of Physical Geography textbooks). The basic notion is this: instead of treating such fields as meteorology, oceanography, botany, ecology, living creatures, aspects of geology, etc. as discrete, self-contained knowledge bases, recognize that they are all part of the same system that controls the Earth, and hence all pointed towards a central common theme, and then cross-link (integrate) the natural shared aspects into a single holistic approach to understanding the Earth. The practioners of this new emphasis on the "Earth System" are now united by participating in joint study efforts such as the International Geosphere and Biosphere Program and by having laid out specifications for highly efficient data gathering, both in/on/above the Earth from the field and through a new family of satellites (the EOS program). This first page explores some of the background to the fundamentals of a coordinated Earth Observation effort and cites several of the important information links to the programs.
At first glance, the themes considered under the purview of Earth System Science (ESS) might seem to be a hodgepodge of unrelated subjects. The common thread, however, is global warming. While the actual interrelationships may at first glance seem unconnected on this page, it does give several examples of some of the frequently cited topics in different subjects under study (e.g., volcanic eruptions, ocean parameters (particularly sealevel rise), the Greenhouse effect, polar temperatures; El Niño; the Ozone Hole), while showing how observations from space contribute to monitoring these phenomena. Of special interest are the predicted changes in temperatures, sugar maple distribution, and grain yield, regionally or globally, if the current mean carbon dioxide content in the atmosphere is doubled. Satellite observations and measurements play a key role in monitoring these changes; the ability to monitor large areas at once with short repeat times means that these observers are essential tools in controlling the behavior of Earth's atmosphere to minimize the dangers of negative feedback to the temperature status.
WASHINGTON — Climate change is already having detrimental effects in the United States, and those effects are probably going to get worse, a new federal study suggests.
The U.S. Global Change Research Program released the report, titled “Global Climate Change Impacts in the United States,” June 16 during a White House-hosted press conference.

CARBON CAPTURE AND STORAGE:
The new boiler at the Schwarze Pumpe power plant in Spremberg, Germany, captures 95 percent of the carbon dioxide (CO2) from its coal burning—a small demonstration of one option for capturing carbon and compressing it for transportation by pipeline or truck to a place where it can be buried or used. This photo was taken in October 2007 and shows the general layout of the carbon capture and storage addition to the 1,600 megawatt power plant.
