World to be even hotter by century's end
If Earth's past cycles of warming and cooling are any indication, temperatures by the end of the century will be even hotter than current climate models predict, according to a report by University of California, Berkeley, researchers. view more (2006-05-25)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
Global warming dramatically changed ancient forests
The migration of subtropical plants to northern climates may not be too far-fetched if future global warming patterns mirror a monumental shift that took place in the past. view more (2005-11-14)
Greenhouse gas effect consistent over 420 million years
New calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years, according to an article in Nature by geologists at Yale and Wesleyan Universities. view more (2007-03-29)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Methane-Belching Bugs Inspire a New Theory of the Origin of Life on Earth
Two laboratories at Penn State set out to show how an obscure undersea microbe metabolizes carbon monoxide into methane and vinegar. view more (2006-05-15)
New findings show a slow recovery from extreme global warming episode 55 million years ago
Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago, according to a study published this week in the journal... view more...

Global warming will reduce ocean productivity, marine life
A 10-year, satellite-based analysis has shown for the first time that primary biological productivity in the oceans-the growth of phytoplankton that forms the basis for the rest of the marine food chain-is tightly linked to climate change, and would be reduced by global warming. view more (2006-12-07)
Genetic discovery could lead to drought-resistant plants
New knowledge of how plants "breathe" may help us breed and select plants that would better survive scorching summers, says a University of Toronto study. view more (2005-07-19)
Greenhouse theory smashed by biggest stone
A new theory to explain global warming was revealed at a meeting at the University of Leicester (UK) and is being considered for publication in the journal "Science First Hand". view more (2006-03-14)
Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century. view more (2007-07-26)
Temperate Forests Could Worsen Global Warming
Growing a forest might sound like a good idea to combat global warming, since trees draw carbon dioxide from the air and release cool water from their leaves. view more (2005-12-07)
Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia. view more (2005-12-20)
Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations, according to a paper to be presented at the Earth System Processes 2 meeting in Alberta, Canada. view more (2005-08-05)
Flights reveal intriguing information about ice particles in clouds
In the clouds above Darwin, Australia, pilots guided by a team of international climate scientists are now one week into a series of carefully orchestrated flights to obtain key in situ data about tropical clouds. view more (2006-02-06)
2007 ozone hole 'smaller than usual'
The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA's Envisat satellite, this year's ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes. view more (2007-10-04)
Green alga genome project catalogs carbon capture machinery
The genome analysis of a tiny green alga has uncovered hundreds of genes that are uniquely associated with carbon dioxide capture and generation of biomass. view more (2007-10-12)
Microbe has huge role in ocean life, carbon cycle
Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell-and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. view more (2005-08-19)
"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 recent issue of Ecology Letters, Stephenson and van... view more... (2005-04-19)
Volcanic eruptions, ancient global warming linked
A team of scientists announced today confirmation of a link between massive volcanic eruptions along the east coast of Greenland and in the western British Isles about 55 million years ago and a period of global warming that raised sea surface temperatures by five degrees (Celsius) in the tropics and more than six degrees in the Arctic. view more (2007-04-27)
