The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement.In recent years, there has been growing evidence for the hypothesis that the effect of the pandemics in the Americas wasn't confined to killing indigenous peoples. Global climate appears to have been altered as well.Stanford...

Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. These early conservationists disappeared 500 years ago, but centuries later, their soil is still rich in organic matter and nutrients. Now, scientists, environmental groups and policymakers forging the next world climate agreement see biochar not only as an important tool for replenishing soils, but as a...

NASA said it is preparing to launch a satellite that will be capable of spotting the source of carbon emissions. The Orbiting Carbon Observatory (OCO) will give scientists a better understanding of the location of CO2 emissions and absorption. "This is NASA's first spacecraft specifically dedicated to mapping carbon dioxide," said principal investigator David Crisp, who provided more details about the "ËœCO2 Hunter' during the American Geophysical Union's (AGU) Fall Meeting this...

The icy seas between Australia and Antarctica could become a money generator by engineering nature to soak up carbon dioxide and then selling carbon credits worth millions of dollars. But many scientists believe the concept of using nature to mop up mankind's excess CO2 to fight global warming is fraught with risk and uncertainty. An Australian research body suggests more research is needed before commercial ventures are allowed to fertilize oceans on a large scale and over many years to...

Intensifying winds in the Southern Ocean have had little influence on the strength of the Southern Ocean circulation and therefore its ability to absorb carbon dioxide from the atmosphere, according to a study published yesterday in Nature Geoscience. The Southern Ocean slows the rate of greenhouse warming by removing carbon dioxide from the atmosphere and storing it in the ocean. But previous studies raised the alarm by suggesting the Southern Ocean carbon sink is now 'saturated"˜...

A recent ESA campaign has demonstrated how a technique using lasers could be employed to measure carbon dioxide in the atmosphere. The campaign supports one of the main objectives of the candidate Earth Explorer A-SCOPE mission. A-SCOPE (Advanced Space Carbon and climate Observation of Planet Earth) is one of the six candidate Earth Explorer missions that has just completed assessment study. The mission concept, along with the other five, will be presented to the science community at a...

A recent study has found that the Southern Ocean has proved more resilient to global warming than previously thought and remains a major store of mankind's planet-warming carbon dioxide. Oceans act as a brake on climate change by absorbing large portions of the extra CO2 released by mankind through burning fossil fuels or deforestation and experts say the Southern Ocean is the largest of these "carbon sinks." Researchers in the past have suggested the vast ocean between Australia and...

A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. A new Cornell study, published online in Nature Geosciences, quantified the amount of black carbon in Australian soils and found that there was far more than expected, said Johannes Lehmann, the paper's lead author and a Cornell professor of biogeochemistry. The survey was the largest of black carbon ever...

Scientists have long known that life can exist in some very extreme environments. But Earth continues to surprise us. At a European Science Foundation and COST (European Cooperation in the field of Scientific and Technical Research) 'Frontiers of Science' meeting in Sicily in October, scientists described apparently productive ecosystems in two places where life was not known before, under the Antarctic ice sheet, and above concentrated salt lakes beneath the Mediterranean. In both cases,...

NASA's first spacecraft dedicated to studying carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate, has arrived at Vandenberg Air Force Base, Calif., to begin final launch preparations. The Orbiting Carbon Observatory arrived Nov. 11 at its launch site on California's central coast after completing a cross-country trip by truck from its manufacturer, Orbital Sciences Corp. in Dulles, Va. The spacecraft left Orbital on Nov. 8. After final tests, the...
