Study explores how increasing CO2 concentrations may be affecting trees and water and carbon cycles The many environmental issues facing our society are prevalent in the media lately. Global warming, rainforest devastation, and endangered species have taken center stage. Our ecosystem is composed of a very delicate network of interactions among all species and the non-living environment. Predicting how each component of this complex system will respond to the many environmental changes...

Sometimes a picture really is worth a thousand words, particularly when the picture is used to illustrate science. Technology is giving us better pictures every day, and one of them is helping a NASA-funded scientist and her team to explain the behavior of a greenhouse gas. Google Earth -- the digital globe on which computer users can fly around the planet and zoom in on key features -- is attracting attention in scientific communities and aiding public communication about carbon dioxide....

NEW YORK, Sept. 22 /PRNewswire/ -- Mohamed Nasheed, President of Maldives, today affirmed his commitment to biochar as an important means of meeting the country's goal to be "Zero Carbon" by 2020. Announced as part of Climate Week at the UN in New York, this commitment further solidifies the country's position as a leader in combating climate change and highlights the potential of biochar as a solution to growing CO2 emissions. The Maldives have partnered with Carbon Gold, the world's...

In a commentary "The Boundless Carbon Cycle", published in the September issue of "Nature Geoscience", scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based StroudTM Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked a critical player - inland waters. Streams, rivers, lakes, reservoirs, and wetlands play an important role in the carbon...

Climate change, land-use patterns are culprits, scientists to report at Ecological Society of America conferenceWhat do the Gulf of Mexico's "dead zone," global climate change, and acid rain have in common? They're all a result of human impacts to Earth's biology, chemistry and geology, and the natural cycles that involve all three.On August 4-5, 2009, scientists who study such cycles--biogeochemists--will convene at a special series of sessions at the Ecological Society of America (ESA)'s...

U.S. scientists say they have discovered marine microorganisms use manganese and iron to convert methane into carbon dioxide. The Pennsylvania State University researchers said their finding is important because carbon dioxide can produce compounds that sequester carbon in the ocean, reducing the amount of CO2 in the Earth's atmosphere. That process had previously been thought to be dependent on compounds containing sulfur. Graduate student Emily Beal, principal author of the study, said the...

An Australian-led team of scientists says it has determined the amount of frozen carbon in Earth's northern regions is more than double previous estimates. We now estimate the deposits contain over 1.5 trillion tons of frozen carbon, about twice as much carbon as contained in the atmosphere, said Charles Tarnocai of Agriculture and Agri-Food Canada, the study's lead author. Pep Canadell, executive director of Australia's Global Carbon Project and study co-author, said the existence of...

Does ozone have an impact on the ocean's role as a "carbon sink"? Yes, according to researchers from three laboratories (1) attached to INSU-CNRS (2), UPMC, CEA, IRD, MNHN and UVSQ. Using original simulations, they have demonstrated that the hole in the ozone layer reduces atmospheric carbon uptake in the Southern Ocean and contributes to the increase in ocean acidity. These results, which are published online in the journal Geophysical Research Letters, should have a considerable impact on...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
