The tropics may be expanding
Atmospheric temperature measurements by U.S. weather satellites indicate Earth's hot, tropical zone has expanded farther from the equator since 1979, says a study by scientists from the University of Utah and University of Washington.   view more (2006-05-26)

Antarctic ice sheet losing mass, says University of Colorado study
University of Colorado at Boulder researchers have used data from a pair of NASA satellites orbiting Earth in tandem to determine that the Antarctic ice sheet, which harbors 90 percent of Earth's ice, has lost significant mass in recent years.   view more (2006-03-03)

Climatic change and environmental functions of forests
The situation in Navarre with regard to climatic change is one of concern given that gas emissions from the greenhouse effect are even greater than the average in Spain (45%).   view more (2006-05-03)

Yale study: Not enough metals in earth to meet global demand
Researchers studying supplies of copper, zinc and other metals have determined that these finite resources, even if recycled, may not meet the needs of the global population forever, according to a study published in the Proceedings of the National Academy of Sciences.   view more (2006-01-26)

Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences.   view more (2006-04-11)

Global warming not responsible for malaria increase in East African Highlands
Recent increases in malaria in the East African Highlands cannot be attributed to global warming, researchers at the Department of Zoology at Oxford University have shown. It has long been known that malaria in highland areas is hindered by low temperatures which limit the development of the... view more (2002-02-21)

Taking evolution's temperature: Researchers pinpoint the energy it takes to make a species
Writing this week in the Proceedings of the National Academy of Sciences, scientists say higher temperatures near the equator speed up the metabolisms of the inhabitants, fueling genetic changes that actually lead to the creation of new species.   view more (2006-06-01)

Glimpse to past adds weight to global warming forecasts
A new examination of the period of global warming that planet Earth underwent 130,000 years ago is helping scientists to confirm the accuracy of projections for the next century - particularly over Canada's North.   view more (2006-03-24)

Researchers appeal for new regulations to save coral reefs from live fish trade
Researchers are calling for tighter controls on the live reef fish trade, a growing threat to coral reefs, in letters to the international journal Science.   view more (2006-08-07)

Why a Rocky Mountain high?
A University of Utah study shows how various regions of North America are kept afloat by heat within Earth's rocky crust, and how much of the continent would sink beneath sea level if not for heat that makes rock buoyant.   view more (2007-06-25)

Study shows snowfall hasn't increased over Antarctica in last 50 years
An international effort to determine the variability of recent snowfall over Antarctica shows that there has been no real increase in precipitation over the southernmost continent in the last half-century.   view more (2006-08-11)

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)

Environmental lessons from tsunami as world's coastal population doubles
Coastal populations and ecosystems are more likely to bounce back from extreme coastal disasters by protecting local environments and building on local knowledge, according to a report published in Science.   view more (2005-08-12)

Global warming could halt ocean circulation, with harmful results
Absent any climate policy, scientists have found a 70 percent chance of shutting down the thermohaline circulation in the North Atlantic Ocean over the next 200 years, with a 45 percent probability of this occurring in this century.   view more (2005-12-08)

Birds going extinct faster due to human activities
Human activities have caused some 500 bird species worldwide to go extinct over the past five millennia, and 21st-century extinction rates likely will accelerate to approximately 10 additional species per year unless societies take action to reverse the trend, according to a new report.   view more (2006-07-06)

New research detects human-induced climate change at a regional scale
Canadian and British climate scientists have clearly detected human-induced climate change at a regional scale in Canada, southern Europe and China.   view more (2006-09-22)

Phytoplankton bounce back from abrupt climate change
Marine sediment cores contain calcareous plankton - single-celled organisms with a coating or shell of calcium carbonate - as fossils. These tiny photosynthesizing plants float in the ocean and move with the currents.   view more (2006-02-17)

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)

Global Warming Surpassed Natural Cycles in Fueling 2005 Hurricane Season, NCAR Scientists Conclude
Global warming accounted for around half of the extra hurricane-fueling warmth in the waters of the tropical North Atlantic in 2005, while natural cycles were only a minor factor.   view more (2006-06-23)

Volcanoes helped slow ocean warming trend, researchers find
Ocean temperatures might have risen even higher during the last century if it weren't for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity.   view more (2006-02-10)

Coral reef decline-not just overfishing
Coral reefs, the rainforests of the sea, feed a large portion of the world's population, protect tropical shorelines from erosion, and harbor animals and plants with great potential to provide new therapeutic drugs.   view more (2005-08-24)

The critical importance of mangroves to ocean life
Mangroves, the backbone of the tropical ocean coastlines, are far more important to the global ocean's biosphere than previously thought.   view more (2006-02-28)

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)

Sea level on the rise - in real and virtual worlds
The climate system, and in particular sea level, may be responding more quickly to rising carbon emissions than climate scientists have estimated with climate models.   view more (2007-02-05)

Forest fires may lead to cooling of northern climate
Countering hypotheses that forest fires in Alaska, Canada and Siberia warm the climate, scientists at UC Irvine have discovered that cooling may occur in areas where charred trees expose more snow, which reflects sunlight into space.   view more (2006-11-17)
