Geologists make better estimates of rock ages, study global climate change
10-23-2006 · EurekAlert!Ohio State University geologists have found that important rocks from Niagara Gorge -- rock formations that are used to judge the ages of rocks and fossils around North America -- formed five times faster than previously thought. The finding means that scientists will have to re-examine studies of sedimentary rock deposited across North America during the Silurian period, from 416 to 443 million years ago.

- Nitrogen study may improve ecological predictions
01-18-2007 · EurekAlert!
The pattern of nitrogen release from decaying plant material is remarkably similar and predictable across the planet, researchers have concluded in a new study, which should make it easier to understand nutrient dynamics, vegetation growth, estimate carbon release and sequestration and better predict the impacts of climate change.

- Ice Ages and rivers may have affected gorilla diversification
12-10-2007 · EurekAlert!
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans.The collaborative School of Biosciences study shows that the genetic composition of gorilla populations varies across different parts of their current geographic range and that this variation may be tied to Ice Age climate change and river barriers.

A before-and-after study led by Yale biologists, of the effects of 1997 El Niño on the genetic diversity of marine iguanas on the Galápagos Islands, emphasizes the importance of studying populations over time and the need to determine which environmental and biological factors make specific populations more vulnerable than others.

- Will lemmings fall off climate change cliff?
04-20-2007 · EurekAlert!
Contrary to popular belief, lemmings do not commit mass suicide by leaping off cliffs into the sea. A bigger threat to the the rodents is climate change, according to the Wildlife Conservation Society, which is launching a study to examine how these tiny but important players in the ecological health of the far North will fare in the age of global warming.

- Rotting leaf litter study could lead to more accurate climate models
01-18-2007 · EurekAlert!
Bags of decomposing leaf litter have allowed a research team led by scientists at UC Berkeley and Colorado State University to produce an elegantly simple set of equations to calculate the nitrogen released into the soil during decomposition, which in turn could significantly improve the accuracy of global climate change models.

- Studying rivers for clues to global carbon cycle
02-08-2008 · EurekAlert!
In the science world, media and our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. In a study of how organic carbon is processed in rivers, a research team including an engineer, ecologists and microbiologists has determined that carbon processing in rivers is a bigger component of global carbon cycling than previously thought. The team lays out a framework for how scientists should go about assessing those processes.

- Climate policy: It's good to be in the 'RED'
05-10-2007 · EurekAlert!
Tropical deforestation, which releases more than 1.5 billion metric tons of carbon to the atmosphere every year, is a major contributor to global climate change. Recognizing this, a group of forest-rich developing nations have called for a strategy to make forest preservation politically and economically attractive. The result is a two-year initiative, dubbed "Reducing Emissions from Deforestation," launched by the United Nations Framework Convention on Climate Change.

A comprehensive new study authored by University at Buffalo scientists and their colleagues for the first time documents in detail the dynamics of parts of Greenland's ice sheet, important data that have long been missing from the ice sheet models on which projections about sea level rise and global warming are based.

- Deep in arctic mud, geologists find strong evidence of climate change
01-18-2007 · EurekAlert!
How severe will global warming get? Jason P. Briner is looking for an answer buried deep in mud dozens of feet below the surface of lakes in the frigid Canadian Arctic. His group is gathering the first quantitative temperature data over the last millennium from areas in extreme northeastern sections of the Canadian Arctic, such as Baffin Island.
