Fossilized midges provide clues to future climate change
Fossilised midges have helped scientists at the University of Liverpool identify two episodes of abrupt climate change that suggest the UK climate is not as stable as previously thought.   view more (2007-07-10)

NASA airborne expedition chases climate, ozone questions
NASA's Tropical Composition, Cloud and Climate Coupling (TC4) field campaign will begin this summer in San Jose, Costa Rica, with an investigation into how chemical compounds in the air are transported vertically into the stratosphere and how that transport affects cloud formation and climate.   view more (2007-06-28)

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)

Poverty and environment billions could be wasted
Out-of-date policies are undermining unprecedented opportunities for recent aid commitments to improve the environment and combat poverty, according to scientists at a new global research centre launched today.   view more (2007-06-26)

U. of Colorado study shows desert droughts lead to earlier annual mountain snow loss
A new study spearheaded by the University of Colorado at Boulder's National Snow and Ice Data Center indicates wind-blown dust from drought-stricken and disturbed lands in the Southwest can shorten the duration of mountain snow cover hundreds of miles away in the Colorado mountains by roughly a... view more (2007-06-26)

Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.   view more (2007-06-25)

UW-Madison engineers develop higher-energy liquid-transportation fuel from sugar
Plants absorb carbon dioxide from the air and combine it with water molecules and sunshine to make carbohydrate or sugar. Variations on this process provide fuel for all of life on Earth.   view more (2007-06-21)

Arctic ocean history is deciphered by ocean-drilling research team
Sediment cores retrieved from the Arctic's deep-sea floor by the Integrated Ocean Drilling Program's Arctic Coring Expedition (ACEX) have provided long-absent data to scientists who report new findings in the June 21 issue of Nature.   view more (2007-06-21)

Arctic spring comes weeks earlier than a decade ago
In the Earth's cold and icy far north, the harsh winters are giving way to spring weeks earlier than they did just a decade ago, researchers have reported in the June 19th issue of Current Biology, published by Cell Press.   view more (2007-06-19)

Gannet population under threat from global warming
Researchers at the University of Leeds have warned that global warming is a major threat to the gannet, a species known for its stable populations and constant breeding success.   view more (2007-06-19)

Climate models consistent with ocean warming observations
Climate models are reliable tools that help researchers better understand the observed record of ocean warming and variability.   view more (2007-06-19)

Yale journal examines the global impact of cities
The global impact of cities is the focus of cutting-edge research in a special issue of Yale's Journal of Industrial Ecology.   view more (2007-06-18)

Reduced greenhouse gas emissions required to avoid dangerous increases in heat stress, researchers say
A study led by a Purdue University researcher projects a 200 percent to 500 percent increase in the number of dangerously hot days in the Mediterranean by the end of the 21st century if the current rate of greenhouse gas emissions continues. The study found France would be subjected to the largest... view more (2007-06-18)

Researchers examine carbon capture and storage to combat global warming
While solar power and hybrid cars have become popular symbols of green technology, Stanford researchers are exploring another path for cutting emissions of carbon dioxide, the leading greenhouse gas that causes global warming.   view more (2007-06-12)

The woes of Kilimanjaro: Don't blame global warming
The "snows" of Africa's Mount Kilimanjaro inspired the title of an iconic American short story, but now its dwindling icecap is being cited as proof for human-induced global warming.   view more (2007-06-12)

Alzheimer's disease to quadruple worldwide by 2050
More than 26 million people worldwide were estimated to be living with Alzheimer's disease in 2006   view more (2007-06-11)

Who needs environmental monitoring?
We monitor the stock market, the weather, our blood pressure. Yet environmental monitoring is often criticized as being unscientific, expensive, and wasteful.   view more (2007-06-08)

Dirty snow may warm Arctic as much as greenhouse gases
The global warming debate has focused on carbon dioxide emissions, but scientists at UC Irvine have determined that a lesser-known mechanism - dirty snow - can explain one-third or more of the Arctic warming primarily attributed to greenhouse gases.   view more (2007-06-07)

Hundreds of Antarctic Peninsula glaciers accelerating as climate warms
Hundreds of glaciers on the Antarctic Peninsula are flowing faster, further adding to sea level rise according to new research published this week in the Journal of Geophysical Research. Climate warming, that is already causing Antarctic Peninsula increased summer snow melt and ice shelf retreat,... view more (2007-06-06)

New screening method to help find better biofuel crops
In the face of skyrocketing gasoline prices, ethanol has become a hot commodity along with the corn used to make it. Researchers at the US DOE's Ames Laboratory have developed a method to screen other more cost effective and sustainable crops to produce ethanol.   view more (2007-06-06)

Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet.   view more (2007-06-01)

Climate change signal detected in the Indian Ocean
The signature of climate change over the past 40 years has been identified in temperatures of the Indian Ocean near Australia.   view more (2007-05-31)

DNA clues to inform conservation in Africa
Tracing the evolutionary history of wildlife could improve global habitat conservation, a major Cardiff University study has found.   view more (2007-05-23)

CO2 emissions increasing faster than expected
Carbon dioxide emissions from fossil fuels - the principal driver of climate change - have accelerated globally at a far greater rate than expected over recent years.   view more (2007-05-22)

Scientists concerned about effects of global warming on infectious diseases
As the Earth's temperatures continue to rise, we can expect a signficant change in infectious disease patterns around the globe. Just exactly what those changes will be remains unclear, but scientists agree they will not be for the good.   view more (2007-05-22)
