University launches new initiative for Earth System Modelling

New genomic model defines microbes by diet -- provides tool for tracking environmental change
In line with the U.S. Department of Energy (DOE) interest in characterizing the biotic factors involved in global carbon cycling, the DOE Joint Genome Institute (JGI) characterizes a diverse array of plants, microorganisms, and the communities in which they reside to inform options for reducing and stabilizing atmospheric greenhouse gases. view more (2009-09-08)
Understanding the Mediterranean
As millions of holidaymakers will testify, the Mediterranean is uniquely clear - and blue - unlike the cloudy grey of many coastal waters. But how many of its grateful bathers realise that the Med is so crystal clear because it's the ocean equivalent of the Sahara desert? view more (2004-12-01)
Fossil wood gives vital clues to ancient climates
New research into a missing link in climatology shows that the Earth was not overcome by a greenhouse period when dinosaurs dominated, but experienced rapid fluctuations in temperature and sea level change that resulted in a balance of the global carbon cycle. view more (2006-02-24)
Ancient British bog provides clue to global warming
Analysis of sediments from a British bog suggest that methane emissions increased due to intense global warming around 55 million years ago. view more (2007-09-20)
AMENDED CONVENTION WIDENS EUMETSAT’S REMIT
All Member States have now finally approved EUMETSAT’s amended Convention which widens the Organisation’s objectives to include the operational monitoring of the climate and detection of climate change. The Convention is the legal basis for EUMETSAT. It is a treaty under international law amongst all the Member States that constitutes... view more... (2000-11-17)
Global change conference sets the scene for next round of Kyoto Protocol talks
Throughout the world, scientists are seeing clear signs that the Earth is rapidly changing. Tropical glaciers are melting fast and some will disappear within 15 years if current warming trends continue. Fifty percent of the land surface has been modified and more than half the world’s accessible freshwater is being used directly or... view more... (2001-04-10)
Sustainable development now more urgent than ever, says IGBP scientist
GOTHENBURG - The global environment is in the midst of a profound transformation making sustainable development a matter of urgency, said Dr Will Steffen from the International Geosphere-Biosphere Programme (IGBP, www.igbp.kva.se) at a major international consultation on education for sustainability in Gothenburg today. Dr Steffen, Executive... view more... (2004-05-05)
Cold climate produced by algae contributed to onset of multicellular life
The rise of multicellular animals about 540 million years ago was a turning point in the history of life. A group of Finnish scientists suggests a new climate-biosphere interaction mechanism for the underlying processes in a new study. view more (2007-02-14)
Researchers link ocean organisms with increased cloud cover and potential climate change
Atmospheric scientists have reported a new and potentially important mechanism by which chemical emissions from ocean phytoplankton may influence the formation of clouds that reflect sunlight away from our planet. view more (2006-11-08)
Bigelow Laboratory Scientists develop new approach to study marine microbes
Drs. Michael Sieracki and Ramunas Stepanauskas, scientists at Bigelow Laboratory, have proven a new approach of obtaining genetic codes of ocean microbes, based on the analysis of individual unicellular organisms. view more (2007-05-22)
Killer bees may increase food supplies for native bees
Aggressive African bees were accidentally released in Brazil in 1957. As "killer bees" spread northward, David Roubik, staff scientist at the Smithsonian Tropical Research Institute, began a 17-year study that revealed that Africanized bees caused less damage to native bees than changes in the weather and may have increased the... view more...

How chilly was the last ice age?
Polar oceans permanently covered with ice, temperatures ten to twelve degrees Celsius lower than today in the North Atlantic region, tropical oceans on the other hand only two degrees Celsius below modern values: Until quite recently these were the general ideas climate researchers had about the climax of the last ice age 20.000 years ago. Now... view more... (1999-05-03)
Is there anybody out there?
Is there anybody out there? Probably not, according to a scientist from the University of East Anglia. A mathematical model produced by Prof Andrew Watson suggests that the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve and the remaining life span of Earth. view more (2008-04-17)
Study finds healthy intestinal bacteria within chicken eggs: Finding could have important implications for poultry industry, food safety
The conventional wisdom among scientists has long been that birds acquire the intestinal bacteria that are necessary for good health from their environment, but a new University of Georgia study finds that chickens are actually born with those bacteria. view more (2008-06-04)
Bovine tuberculosis in wildlife threatens endangered lynx and cattle health
In an epidemiological survey of Spain's Doñana National Park, the findings of which are published on July 23 in the journal PLoS ONE, Christian Gortázar and colleagues studied the prevalence of bovine tuberculosis (bovine TB) infection among populations of wild boar, red deer and fallow deer in the national park, which is located in... view more...

Understanding the oceans microbes is key to the Earth's future
Life on Earth may owe its existence to tiny microorganisms living in the oceans, but the effect of human-induced change on the vital services these microbes perform for the planet remains largely unstudied. view more (2005-12-09)
Ecologists say metabolism accounts for why natural selection favors only some species
Why are some species of plants and animals favored by natural selection? And why does natural selection not favor other species similarly? view more (2008-11-04)
Ancient organisms discovered in Canadian gold mine
Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task. view more (2007-08-21)
Earlier global warming produced a whole new form of life
Researchers from McGill University, along with colleagues from the California Institute of Technology, the Curie Institute in Paris, Princeton University and other institutions, have unearthed crystalline magnetic fossils of a previously unknown species of microorganism that lived at the boundary of the Paleocene and Eocene epochs, some 55 million... view more...
