- New research may lead to better climate models for global warming, El Niño
12-07-2007 · EurekAlert!
From nine different countries, 150 scientists are starting a program to gain insights about the Earth's climate and the complex system involving the oceans, atmosphere and land. They are studying the Southeastern Pacific Ocean off South America's west coast -- research that should improve global computer climate models, which would lead to improved predictions about global warming and El Niños, said C. Roberto Mechoso, UCLA professor of atmospheric and oceanic sciences, who chairs the program.

- Global warming will reduce ocean productivity, marine life
12-06-2006 · EurekAlert!
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans -- the growth of phytoplankton that forms the basis for the rest of the marine food chain -- is tightly linked to climate change, and would be reduced by global warming. This would cause a rapid, overall reduction in marine life.

- Dental crowns reveal the diet of a species:
12-14-2006 · EurekAlert!
According to recent research, the complexity of tooth surfaces reveals the diet of a species. Scientists at the University of Helsinki's Institute of Biotechnology and Department of Geology showed that the more complex the surface of an animal's teeth, the greater the share of vegetables in its diet. For instance, the teeth of carnivores and rodents differ in almost every aspect, but if a carnivore and a rodent eat similar food, their teeth are equally complex. The results were published in Nature.

- North America's northernmost lake affected by global warming
09-26-2007 · EurekAlert!
Analyses conducted by researchers from Université Laval's Center for Northern Studies reveal that the continent's northernmost lake is affected by climate change. The research team reports that life in Ward Hunt Lake, located on a small island in the Canadian Arctic, has undergone major transformations within the last two centuries. The speed and range of these transformations suggest that climate change related to human activity could be at the source of this phenomenon.
