Volcanoes cool the tropics, say researchers
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics-but suggest that such effects may have been masked in the 20th century by rising global temperatures.   view more (2009-01-06)

Abrupt Climate Shifts May Come Sooner, Not Later
The United States could suffer the effects of abrupt climate changes within decades-sooner than some previously thought--says a new government report.   view more (2008-12-22)

Study: Did early climate impact divert a new glacial age?
The common wisdom is that the invention of the steam engine and the advent of the coal-fueled industrial age marked the beginning of human influence on global climate.   view more (2008-12-18)

Post-pandemic reforestation in New World helped trigger Little Ice Age, Stanford researchers say
The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement.    view more (2008-12-18)

Study links ecosystem changes in temperate lakes to climate warming
Unparalleled warming over the last few decades has triggered widespread ecosystem changes in many temperate North American and Western European lakes, say researchers at Queen's University and the Ontario Ministry of the Environment.   view more (2008-12-17)

Europa does the wave to generate heat
One of the moons in our solar system that scientists think has the potential to harbor life may have a far more dynamic ocean than previously thought.   view more (2008-12-12)

Snowy owl -- a marine species?
Wildlife satellite studies could lead to a radical re-thinking about how the snowy owl fits into the Northern ecosystem.    view more (2008-12-11)

UD researchers focus on building telescope at South Pole
It's 40 degrees F below zero (with the wind chill) at the South Pole today. Yet a research team from the University of Delaware is taking it all in stride.   view more (2008-12-10)

Jupiter's rocky core bigger and icier, model predicts
Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms.   view more (2008-11-26)

Getting Warmer? Prehistoric Climate Can Help Forecast Future Changes
The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature.    view more (2008-11-25)

Understanding Europe's topography
Europe's shape is in a constant change: The Mediterranean basin is shrinking, the Alps are rising and pushing North, and Scandinavia is still rebounding after having been crushed by the weight of a thick and huge ice sheet in the ice ages. But what did Europe look like in the past, what are the... view more (2008-11-24)

Measuring water from space
Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions.   view more (2008-11-13)

Revised theory suggests carbon dioxide levels already in danger zone
If climate disasters are to be averted, atmospheric carbon dioxide (CO2) must be reduced below the levels that already exist today, according to a study published in Open Atmospheric Science Journal by a group of 10 scientists from the United States, the United Kingdom and France.    view more (2008-11-10)

When it comes to sea level changing glaciers, new NASA technique measures up
A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years.   view more (2008-11-07)

Sunlight has more powerful influence on ocean circulation and climate than North American ice sheets
A study reported in today's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods.   view more (2008-11-07)

Dry spells spelled trouble in ancient China
Chinese history is replete with the rise and fall of dynasties, but researchers now have identified a natural phenomenon that may have been the last straw for some of them: a weakening of the summer Asian Monsoons.   view more (2008-11-07)

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)

Very cold ice films in laboratory reveal mysteries of universe
The universe is full of water, mostly in the form of very cold ice films deposited on interstellar dust particles, but until recently little was known about the detailed small scale structure.   view more (2008-11-06)

Coral reefs found growing in cold, deep ocean
Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 metres under the surface of the Atlantic.   view more (2008-11-05)

What is really happening to the Greenland icecap?
The Greenland ice cap has been a focal point of recent climate change research because it is much more exposed to immediate global warming than the larger Antarctic ice sheet.   view more (2008-11-03)

FSU Historian's Arctic research has him sitting on top of the world
It's one of the coldest and most remote areas on Earth, but the Arctic region has long held great strategic interest for a number of nations. Now, a Florida State University researcher is leading an international team that is working to produce one of the most comprehensive histories to date of the... view more (2008-10-30)

Arctic sea ice thinning at record rate
The thickness of sea ice in large parts of the Arctic declined by as much as 19% last winter compared to the previous five winters, according to data from ESA's Envisat satellite.   view more (2008-10-29)

Scientists probe Antarctic glaciers for clues to past and future sea level
Scientists from the U.S., U.K. and Australia have teamed up to explore two of the last uncharted regions of Earth, the Aurora and Wilkes Subglacial Basins, immense ice-buried lowlands in Antarctica with a combined area the size of Mexico.   view more (2008-10-28)

Stress affects older adults more than young adults
Life can be stressful, whether you're an individual watching the stock market crash or a commuter stuck in traffic. A new study, forthcoming in the journal Psychological Science, examines how stress affects decision-making and finds that older adults alter their behavior more than young adults when... view more (2008-10-28)

Research around the North Pole
The German research vessel Polarstern has returned today to Bremerhaven from the Arctic Sea. It has cruised as the first research vessel ever both the Northeast and the Northwest Passages and thereby circled the North Pole.   view more (2008-10-21)
