Study warns climate change and deforestation will lead to declines in global bird diversity
06-04-2007 · EurekAlert!Global warming and the destruction of natural habitats will lead to significant declines and extinctions in the world’s 8,750 terrestrial bird species over the next century, according to a study conducted by biologists at the University of California, San Diego and Princeton University.

- 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.

- Climate change creates dramatic decline in red-winged black bird population
11-13-2006 · EurekAlert!
Global warming strikes again. A University of Illinois researcher reports that a red-winged black bird population in Ontario, Canada has decreased by 50 percent since 1972. The decrease is related to a positive shift in the North Atlantic Oscillation which has resulted in warmer, wetter winters in the southeastern United States.

- 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.

- New study warns limited carbon market puts 20 percent of tropical forest at risk
08-13-2007 · EurekAlert!
In an ironic twist, 11 countries that have avoided widespread destruction of their tropical forest are at risk of being left out of an emerging carbon market intended to promote rainforest conservation to combat climate change.A new study warns that "high forest cover with low rates of deforestation" nations could become the most vulnerable targets for deforestation if the Kyoto Protocol and upcoming negotiations on carbon trading fail to include intact standing forest.

- Global climate change: The impact of El Niño on Galápagos marine iguanas
12-11-2007 · EurekAlert!
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.

- New research shows climate change triggers wars and population decline
11-21-2007 · EurekAlert!
Climate change may be one of the most significant threats facing humankind. A new study shows that long-term climate change may ultimately lead to wars and population decline. The study, published Nov. 19 in the early edition of the journal Proceedings of the National Academy of Sciences, revealed that as temperatures decreased centuries ago during a period called the Little Ice Age, the number of wars increased, famine occurred and the population declined.

- Land conversion and climate threaten land birds
06-04-2007 · EurekAlert!
Evaluating changes in range size of land bird species using Millenium Ecosystem Assessment scenarios reveals that land conversion, as well as climate change, will lead to the decline of many species, particularly those in the tropics.

- Climate change isolates Rocky Mountain butterflies
08-13-2007 · EurekAlert!
Expanding forests in the Canadian Rocky Mountains are slowly isolating groups of alpine butterflies from each other, which may lead to the extinction of the colourful insects in some areas, says a new study from the University of Alberta.

- New study increases concerns about climate model reliability
12-11-2007 · EurekAlert!
A new study comparing the composite output of 22 leading global climate models with actual climate data finds that the models do an unsatisfactory job of mimicking climate change in key portions of the atmosphere. This research, published online Wednesday in the Royal Meteorological Society's International Journal of Climatology, raises new concerns about the reliability of models used to forecast global warming.
