Modeling of long-term fossil fuel consumption shows 14.5 degree hike in temperature
If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day.   view more (2005-12-07)

Ecology Drives The Worldwide Distribution Of Human Diseases
Mounting evidence suggests that ecological and climatic conditions influence the emergence, spread, and recurrence of infectious diseases. Global climate change is likely to aggravate climate-sensitive diseases in unpredictable ways. Increasingly, public health programs aimed at preventing and... view more (2004-06-09)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

March of the giant penguins
Giant prehistoric penguins? In Peru? It sounds more like something out of Hollywood than science, but a researcher from North Carolina State University along with U.S., Peruvian and Argentine collaborators has shown that two heretofore undiscovered penguin species reached equatorial regions tens of... view more (2007-06-26)

Irrigation may not cool the globe in the future
Expansion of irrigation has masked greenhouse warming in California's Central Valley, but irrigation may not make much of a difference in the future, according to a new study in the Aug. 13 edition of the Proceedings of the National Academy of Sciences.   view more (2007-08-15)

Rising temperatures will lead to loss of trout habitat in the southern Appalachians
USDA Forest Service (FS) research projects that between 53 and 97 percent of natural trout populations in the Southern Appalachians could disappear due to the warmer temperatures predicted under two different global climate circulation models.   view more (2006-10-05)

Bad sign for global warming: Thawing permafrost holds vast carbon pool
Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.   view more (2008-09-04)

Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today.   view more (2007-12-11)

New ice cores expand view of climate history
Two new studies of gases trapped in Antarctic ice cores have extended the record of Earth's past climate almost 50 percent further, adding another 210,000 years of definitive data about the makeup of the Earth's atmosphere and providing more evidence of current atmospheric change.   view more (2005-11-28)

'Cooling down' begins at Svalbard Global Seed Vault
Refrigeration units began pumping chilly air deep into an Arctic mountain cavern today, launching the innovative and critical "cooling down" phase of the Svalbard Global Seed Vault in advance of its official opening early next year as a fail-safe repository of the world's vital food crops.   view more (2007-11-16)

"Live fast, die young" applies to forests, too.
Forests provide humans with economically important and often irreplaceable products and services, and affect global climate by acting as sources and sinks of heat-trapping carbon dioxide. Yet the possible responses of forests to ongoing environmental changes are poorly understood. In the most... view more (2005-04-19)

New membrane strips carbon dioxide from natural gas faster and better
A modified plastic material greatly improves the ability to separate global warming-linked carbon dioxide from natural gas as the gas is prepared for use, according to engineers at The University of Texas at Austin who have analyzed the new plastic's performance.   view more (2007-10-12)

Global Cooperation needed on Climate Change
Climate change negotiators meeting next week in Marrakech need to build a global coalition to enhance the adaptation ability already shown by communities vulnerable to climate change. "The impacts of climate change are significant whether you herd goats in the Atlas Mountains of Morocco or work in... view more (2001-10-23)

New developments in assessing fluid flows
Scientists at Oxford University are developing a new Doppler Global Velocimetry (DGV) technique that will enable three-dimensional fluid velocity fields to be imaged reliably and accurately. Over the last twenty years, a number of techniques have been explored to enable clear imaging of fluid... view more (2002-07-03)

New Evidence Of Impact Of Global Changes On Remote Tropical Rainforests
Scientists have shed new light on the impact of global environmental changes on remote tropical forests with studies that show that the rates of growth and death of trees in pristine forests across the Amazon have accelerated substantially in recent decades. The scientists also demonstrate that the... view more (2004-02-06)

Droughts and reservoirs: Finding storage space underground
Odd as it sounds, in some places the smartest way to safeguard the water supply is to let it drain out of the reservoirs and soak into the ground.   view more (2006-09-19)

Chemistry & Industry - 3 June Issue
NEWS Hydrogen is the fuel of the future says Johnson Matthey's CEO (page 4) Christopher Clark, chief executive of Johnson Matthey, warned that the world needs to change from carbon to hydrogen as its major energy source in the next decades, as the effects of global warming become more apparent.... view more (2002-05-30)

Experiment suggests limitations to carbon dioxide 'tree banking'
While 10 years of bathing North Carolina pine tree stands with extra carbon dioxide did allow the trees to grow more tissue, only those pines receiving the most water and nutrients were able to store significant amounts of carbon that could offset the effects of global warming, scientists told a... view more (2007-08-07)

US Climate Change Science Program making good progress in documenting and understanding changes
Climate change research directed by the federal government has made good progress in documenting and understanding temperature trends and related environmental changes on a global scale, says a new report from the National Research Council.   view more (2007-09-14)

Into the abyss: Deep-sixing carbon
Imagine a gigantic, inflatable, sausage-like bag capable of storing 160 million tonnes of CO2 - the equivalent of 2.2 days of current global emissions.   view more (2008-02-19)

WHO's vision for the future (pp 2033; 2083)
In the week that WHO releases its 2003 World Health report (Shaping the Future), Jung-Wook Lee, WHO Director-general, outlines his vision of how WHO will address the global health-care priorities of the coming years. Lee's article comments: 'A world torn by gross health inequalities is in serious... view more (2003-12-17)

Satellites shed light on global warming
As climate change continues to make headlines across the world, participants at the 2007 Envisat Symposium this week are hearing how Earth observation satellites allow scientists to better understand the parameters involved in global warming and how this is impacting the planet.   view more (2007-04-30)

Extreme weather events can unleash a 'perfect storm' of infectious diseases, research study says
An international research team, including University of Minnesota researcher Craig Packer, has found the first clear example of how climate extremes, such as the increased frequency of droughts and floods expected with global warming, can create conditions in which diseases that are tolerated... view more (2008-06-25)

Decline in uptake of carbon emissions confirmed
A decline in the proportion of carbon dioxide (CO2) emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to a paper published today in the US Journal: Proceedings of the National Academy of Science.   view more (2007-10-25)
