MAPUTO (Reuters) - Floods in central Mozambique have killed six people, driven thousands from their homes and forced others to seek refuge in trees and on rooftops, a senior official said on Sunday. The head of Mozambique's national relief agency INGC, Paulo Zucula, said the flooding caused by torrential rains had cut major transport links to neighboring countries.

TEHRAN (Reuters) - Some of the heaviest snowfalls in years caused severe transport disruptions in Iran on Sunday, forcing the cancellation of most flights and the closure of many roads, Iranian media said. All international and domestic flights to and from Tehran were cancelled and some northwestern cities saw their first snow in 20 years. State radio said many roads to and from Tehran were also closed.

North Atlantic Warming Tied To Natural Variability
January 5, 2008 04:14 PM - Duke University

This striking pattern can be explained largely by the influence of a natural and cyclical wind circulation pattern called the North Atlantic Oscillation (NAO), wrote authors of a study published Jan. 3, in Science Express, the online edition of the journal Science. Winds that power the NAO are driven by atmospheric pressure differences between areas around Iceland and the Azores. "The winds have a tremendous impact on the underlying ocean," said Susan Lozier, a professor of physical oceanography at Duke's Nicholas School of the Environment and Earth Sciences who is the study's first author.

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.
