Isabel�s Secrets
September 30 Acoustic sensors, vertical profilers, and drifting buoys were dropped into the path of Isabel to find answers to discover how much rain she dropped, how the water temperature varied, how quickly the water moved and how fiercely the wind blew. (Office of Naval Research) More
Northern Climate, Ecosystems Driven By Cycles of Changing Sunlight
September 26 Emerging geochemical and biological evidence from Alaskan lake sediment suggests that slight variations in the sun's intensity have affected sub-polar climate and ecosystems in a predictable fashion during the last 12,000 years. More
Scientists Determine Biological and Ecosystem Changes in Polar Regions Linked to Solar Variability
September 26 New research indicates that noticeable changes in the sub-polar climate and ecosystems appear to be linked to variations in the sun�s intensity during the past 12,000 years. (University of California-Berkeley) More
Mediterranean Hot Flush Detected After Scorching Summer
September 24 Results returned from ESA�s Envisat environmental satellite show that, due a record-breaking hot summer, Mediterranean waters off Crete increased by about three degrees Celsius since the previous year. (European Space Agency) More
Atmospheric Carbon Dioxide Greater 1.4 Billion Years Ago
September 17 According to new research, the atmospheric CO2 level 1.4 billion years ago was at least ten to 200 times greater than today. (Virginia Tech) More
Ancient Relatives of Algae Yield New Insights into Role of CO2 in Earth�s Early Atmosphere
September 17 Greenhouse gas has been playing a critical role in warming our planet for billions of years, according to a new study that looks at the photosynthetic cycle by which plants convert light energy and CO2 into cellular tissue. (National Science Foundation) More
Hurricane Isabel Poised for Mid-Atlantic Downpour
September 16 While Hurricane Isabel has no choice but to turn westward into the mid Atlantic states as it moves up the eastern seaboard, the question remains where exactly will it turn and which states will feel her fury, according to a Penn State meteorologist. (Penn State) More
New Technology Helps Fire Managers Anticipate Smoke Problems
September 15 A new technology is allowing professionals and ordinary citizens to coordinate outdoor activities around fire operations. (USDA Forest Service, Pacific Northwest Research Station) More
Role of Tropics in Global Climate Change Gains Attention
September 10 The tropics are being recognized as an important element in the dynamic process of global climate change. A recent investigation sheds light on the role of the tropics in climate change at the end of the last ice age. More
New Colorado U. Study Shows Increase in Fungal Metabolism Under the Snow
September 4 A new study has shown that microbes living under the tundra snow pack ramp up their populations in late winter, a finding with implications for changing estimates of carbon dioxide levels in Earth's atmosphere. (University of Colorado at Boulder) More
Largest Arctic Ice Shelf Breaks Up, Draining Freshwater Lake
September 3 The largest ice shelf in the Arctic has broken, and scientists who have studied it closely say it is evidence of ongoing and accelerated climate change in the north polar region. (American Geophysical Union) More
