Scientists warn of climate change risk to marine turtles
02-19-2007 · EurekAlert!North American marine turtles are at risk if global warming occurs at predicted levels, according to scientists from the University of Exeter. An increase in temperatures of just one degree Celsius could completely eliminate the birth of male turtles from some beaches. A rise of three degrees Celsius would lead to extreme levels of infant mortality and declines in nesting beaches across the USA.

- Scientists develop new measure of 'socioclimactic' risk
12-10-2007 · EurekAlert!
Researchers have taken a first step toward quantifying the "socioclimactic" exposure of different countries to future climate change. The research team found that China, India and the United States face substantial exposure relative to other nations. By integrating state-of-the-art global climate model experiments with socioeconomic indicators of poverty, wealth and population, we create a unique measure of 'socioclimactic' risk for each nation.

- Climate change threatens wild relatives of key crops
05-21-2007 · EurekAlert!
Wild relatives of plants such as the potato and the peanut are at risk of extinction, threatening a valuable source of genes that are necessary to boost the ability of cultivated crops to resist pests and tolerate drought, according to a new study released today by scientists of the Consultative Group on International Agricultural Research (CGIAR). The culprit is climate change, the researchers said.

- Scientists reveal first-ever global map of total human effects on oceans
02-14-2008 · EurekAlert!
More than 40 percent of the world's oceans are heavily affected by human activities, and few if any areas remain untouched, according to the first global-scale study of human influence on marine ecosystems. By overlaying maps of 17 different activities such as fishing, climate change, and pollution, the researchers have produced a composite map of the toll that humans have exacted on the seas.

- Immediate action needed to save corals from climate change
12-13-2007 · EurekAlert!
The journal Science has published a paper today that is the most comprehensive review to date of the effects rising ocean temperatures are having on the world’s coral reefs. "The Carbon Crisis: Coral Reefs under Rapid Climate Change and Ocean Acidification," co-authored by 17 marine scientists from seven different countries, reveals that most coral reefs will not survive the drastic increases in global temperatures and atmospheric CO2 unless governments act immediately to combat current trends.

- Dung happens and helps scientists
02-15-2008 · EurekAlert!
A scientist at Northern Arizona University is in charge of the largest animal dung collection in the world, used for clues about animal evolution and extinction, Ice Age existence and climate change. Researcher Jim Mead admits it is a bizarre resource, but he is one of many around the globe who access dung for DNA information. Mead, a dung authority, continues to grow the collection with specimens from as far away as Siberia.

- The insides of clouds may be the key to climate change
02-17-2007 · EurekAlert!
As climate change scientists develop ever more sophisticated climate models to project an expected path of temperature change, it is becoming increasingly important to include the effects of aerosols on clouds, according to Joyce E. Penner, a leading atmospheric scientist at the University of Michigan.

- Coral reefs may be protected by natural ocean thermostat
02-07-2008 · EurekAlert!
Natural processes may prevent oceans from warming beyond a certain point, helping protect some biologically diverse coral reefs from the impacts of climate change. A new study, by scientists at NCAR and the Australian Institute of Marine Science, finds evidence that an ocean "thermostat" is helping regulate sea-surface temperatures.
