Rapid temperature increases above the Antarctic
A new analysis of weather balloon observations from the last 30 years reveals that the Antarctic has the same 'global warming' signature as that seen across the whole Earth, but is three times larger than that observed globally. view more (2006-03-31)
Climate change aims need to be better integrated
Specific measures to tackle climate change, such as emissions trading, will only be successful if they are coherently supported by other government policies addressing economic and social issues, says a report published today by the Partnership for European Environmental Research (PEER). PEER membership is formed from seven of the biggest European... view more... (2009-03-27)
Ozone hole recovery may reshape southern hemisphere climate change
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA. view more (2008-04-25)
Limited climate tracking in European trees despite 10,000 years of postglacial warmth
The relative roles of environment and history as controls of large-scale species distributions is a crucial issue in biogeography and macroecology. In the forthcoming issue of Ecology Letters Svenning & Skov use bioclimatic modelling to show that among 55 native European tree species, 36 occupy less than 50% of their climatically suitable... view more...

ISHLT membership explores expansion of computer modeling system for organ allocation
The International Society for Heart and Lung Transplantation (ISHLT) announces evaluation of a new mathematical modeling system for lung allocation in the United States and the ethical issues surrounding organ allocation facing patients awaiting transplants. view more (2007-04-26)
Southampton scientists unravel 8,200-year-old climate riddle
Palaeoceanographers from the Southampton Oceanography Centre have shed new light on the world's climate behaviour over 8,200 years ago. In an article published this week in Nature, they demonstrate that a sudden drop in temperature lasting 200 years cannot be used as a template for the modern day threat of rapid climate change. view more (2005-04-21)
Impact of global warming on weather patterns underestimated
The impact of global warming on European weather patterns has been underestimated, according to a new report published in Nature this week. view more (2005-09-22)
Field tests unite weather and climate models
Researchers from NASA's Goddard Space Flight Center (GSFC) and several other government and academic institutions have created four new supercomputer simulations that for the first time combine their mathematical computer models of the atmosphere, ocean, land surface and sea ice. view more (2005-07-20)
Researchers perform multi-century high-resolution climate simulations
Using state-of-the-art supercomputers, Lawrence Livermore National Laboratory climate scientists have performed a 400-year high-resolution global ocean-atmosphere simulation with results that are more similar to actual observations of surface winds and sea surface temperatures. view more (2008-04-02)
Climate shifts — probability of randomness
Severe climate changes during the last ice-age could have been caused by random chaotic variations on Earth and not governed by external periodic influences from the Sun. This has been shown in new calculations by a researcher at the Niels Bohr Institute, Copenhagen University. view more (2007-03-12)
New instrument to investigate climate change
A new instrument that measures the Earth's radiation balance, the energy source that drives our climate, is being launched aboard a satellite today (27 August 2002). Geostationary Earth Radiation Budget (GERB) is the first instrument that can measure the radiation balance from a geostationary orbit (ie. it will stay at the same point above the... view more...

Climate Change"¦ The Facts
Further proof of the reality of climate change was made available to the planet today with the publication of Climate Change 2001. The three volumes, running to some 2,600 pages, are published by Cambridge University Press on behalf of the Intergovernmental Panel on Climate Change (IPCC). Together they form the most comprehensive picture of the... view more... (2001-07-11)
Fire is important part of global climate change, report scientists
Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that raises... view more...

Agricultural methods of early civilizations may have altered global climate, study suggests
Massive burning of forests for agriculture thousands of years ago may have increased atmospheric carbon dioxide enough to alter global climate and usher in a warming trend that continues today, according to a new study that appears online Aug. 17 in the journal Quaternary Science Reviews. view more (2009-08-17)
Warming most evident at high latitudes, but greatest impact will be in tropics
The impact of global warming has become obvious in high latitude regions, including Alaska, Siberia and the Arctic, where melting ice and softening tundra are causing profound changes. view more (2005-08-15)
UCSD researchers make first direct observations of biological particles in high-altitude ice clouds
A team of UC San Diego-led atmospheric chemistry researchers moved closer to what is considered the "holy grail" of climate change science when it made the first-ever direct detection of biological particles within ice clouds. view more (2009-05-18)
Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the most important. To understand the capacity of... view more...

Using satellite observations to study photosynthetic trends in northern circumpolar high latitudes
Using time series analyses of a 22-year record of satellite observations across the northern circumpolar high latitudes, scientists at the Woods Hole Research Center are assessing trends in vegetation photosynthetic activity. view more (2006-05-18)
Scientists develop mathematical model to predict the immune response to influenza
Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1). view more (2009-05-14)
Ecologists use oceanographic data to predict future climate change
Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. view more (2008-11-07)
