Northern bogs may have helped kick-start past global warming
10-12-2006 · EurekAlert!Methane gas released by peat bogs in the northern-most third of the globe helped fuel the last major round of global warming, which drew the ice age to a close between 11,000 and 12,000 years ago, conclude scientists from UCLA and the Russian Academy of Sciences.

- Ancient fish bones reveal impacts of global warming beneath the sea
12-12-2007 · EurekAlert!
Through the study of archaeological material, tax accounts, church registers and account books of monasteries, an international group of fisheries ecologists and fisheries/maritime historians have drawn a picture of marine life in the northern European seas as it looked in the past. Their findings are presented in a special issue of Fisheries Research "History of Marine Animal Populations and their Exploitation in Northern Europe."

- Ancient British bog provides clue to global warming
09-19-2007 · EurekAlert!
Dr. Richard Pancost from the University of Bristol and colleagues, publishing today in Nature, show that carbon isotope values of hopanoids -- compounds made by bacteria -- suddenly decrease in a manner that can only be explained by switching to a diet of methane. This suggests that methane emissions must have increased at that time.

11-13-2007 · EurekAlert!
An international team of researchers, led by the University of Sheffield, has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming.

- Rising CO2 signals wetter storms for Northern Hemisphere, says CU-Boulder study
12-11-2007 · EurekAlert!
While two new studies by researchers at the University of Colorado at Boulder's Cooperative Institute for Research in Environmental Sciences predict wetter storms for the Arctic and for the Northern Hemisphere because of global warming, whether or not this means more net precipitation depends on the latitude.

- 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.

- Carbon sink capacity in northern forests reduced by global warming
01-02-2008 · EurekAlert!
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period has on average decreased due to warmer autumn temperatures. Many northern terrestrial ecosystems currently lose carbon dioxide in response to autumn warming, offsetting 90 percent of the increased carbon dioxide uptake during spring.

- Stabilizing climate requires near-zero carbon emissions
02-14-2008 · EurekAlert!
Now that scientists have reached a consensus that carbon dioxide emissions from human activities are the major cause of global warming, the next question is: How can we stop it? Can we just cut back on carbon, or do we need to go cold turkey? According to a new study by scientists at the Carnegie Institution, halfway measures won't do the job. To stabilize our planet's climate, we need to find ways to kick the carbon habit altogether.
