- Changes in west coast marine ecosystems significant
02-16-2007 · EurekAlert!
The California Current system has experienced significant changes during the past decade, resulting in dramatic variations in the ecosystem, characterized by shifts in phytoplankton production, expanding hypoxic zones, and the collapse of marine food webs off the western coast of the United States. These changes, driven by new wind patterns, are consistent with predictive models of global climate change.

- Evidence From Ice Age That Climate Change Can Have A Rapid Effect On Ocean Circulation
10-09-2006 · ScienceDaily
Sudden shifts in temperature over Greenland and tropical rainfall patterns during the last ice age have been linked for the first time to rapid changes in the salinity of the north Atlantic Ocean. The results provide further evidence that climate change can have a direct and rapid impact on ocean circulation and chemistry.

- New evidence of the link between carbon dioxide emissions and climate change in boreal ecosystems
02-18-2007 · EurekAlert!
New research aimed at understanding the link between carbon dioxide emissions and climate change in boreal systems has found clear links between both spring and fall temperature changes and carbon uptake/loss. Dr. Kevin Robert Gurney, assistant professor in the Earth & Atmospheric Science/Agronomy at Purdue University and associate director of the Purdue Climate Change Research Center, presented these results at the American Association for the Advancement of Science meeting in San Francisco, Calif., on December 17.

- 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.

- Frequency of Atlantic hurricanes doubled over last century, climate change suspected
07-29-2007 · EurekAlert!
About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis. The study concludes that warmer sea surface temperatures and altered wind patterns associated with global climate change are fueling much of the increase.

- Global warming and your health
10-23-2006 · EurekAlert!
Global warming could do more to hurt your health than simply threaten summertime heat stroke, says a public health physician. Although heat-related illnesses and deaths will increase with the temperatures, climate change is expected to also attack human health with dirtier air and water, more flood-related accidents and injuries, threats to food supplies, hundreds of millions of environmental refugees, and stress on and possible collapse of many ecosystems that now purify air and water.
