Northern plants 'losing carbon' due to warming
January 5, 2008 04:05 PM - , SciDevNet
[BEIJING] Global warming could cause plants in northern regions to lose carbon to the atmosphere rather than sequester it, according to a new international study. The research, published in Nature yesterday (3 January), looked at atmospheric carbon dioxide concentrations and carbon dioxide held in ecosystems such as forests in the Northern Hemisphere in the past 20 years.
First-ever study to link increased mortality specifically to carbon dioxide emissions
January 4, 2008 09:05 AM - Stanford University
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency’s recent ruling against states setting specific emission standards for this greenhouse gas based in part on the lack of data showing the link between carbon dioxide emissions and their health effects.
2008 to be in top 10 warmest years say forecasters
January 3, 2008 02:24 PM - Reuters
LONDON (Reuters) - 2008 will be slightly cooler than recent years globally but will still be among the top 10 warmest years on record since 1850 and should not be seen as a sign global warming was on the wane, British forecasters said. The Met Office and experts at the University of East Anglia on Thursday said global average temperatures this year would be 0.37 of a degree Celsius above the long-term 1961-1990 average of 14 degrees and be the coolest since 2000.
Heavy snow blankets Romania and Bulgaria

Meteorologists said the snow, which had been falling for two days, was expected to continue throughout Romania until late on Thursday, with temperatures expected to fall as low as minus 16 degrees Celsius (3 degrees Fahrenheit).
Global warming hits Australia with fires and floods

CANBERRA (Reuters) - Australia endured bushfires, floods and record high temperatures in its drought-ravaged foodbowl in 2007 as global warming brought the nation's sixth hottest year on record, the weather bureau said on Thursday.
Fifteen states sue EPA over auto emissions

HARTFORD, Connecticut (Reuters) - Fifteen states said on Wednesday they filed a lawsuit against the federal Environmental Protection Agency in a bid to tighten regulations of greenhouse gas emissions from cars. Reporting by Jason Szep; Editing by Jeffrey Benkoe
Loosing more than we gain from Autumn warming in the north
January 2, 2008 02:04 PM -
Gif-sur-Yvette, France - An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures.
Good News About Ocean Methane
January 1, 2008 10:21 PM - University of California, Santa Barbara
Santa Barbara, Calif. - Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara. About half of these bubbles dissolve into the ocean, but the fate of this dissolved methane remains uncertain.
Deep-sea species' loss could lead to oceans' collapse, study suggests
January 1, 2008 09:49 PM - University of Marche, Italy
University of Marche, Italy - The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press. In a global-scale study, the researchers found some of the first evidence that the health of the deep sea, as measured by the rate of critical ecosystem processes, increases exponentially with the diversity of species living there.
Beijing introduces cleaner fuel standards
January 1, 2008 08:36 PM - Reuters
BEIJING (Reuters) - China has introduced cleaner fuel standards in its capital Beijing, its latest effort to curb the city's notorious pollution ahead of the Olympic Games in August. Under the new standards, retailers will be required to supply gasoline and diesel equivalent to the Euro IV standard, a move that will cut emissions of acid rain-causing sulphur dioxide by 1,840 tonnes, the China Daily said on Wednesday, citing Beijing's Environmental Protection Bureau.
