Several "new" craters found in Siberia
Genetics reveals where emperor penguins survived the last ice age
A study of how climate change has affected emperor penguins over the last 30,000 years found that only three populations may have survived during the last ice age, and that the Ross Sea in Antarctica was ...
Antarctica's retreating ice may re-shape Earth
(AP)—From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can't be seen is the battle raging underfoot to re-shape Earth.
The sun has more impact on the climate in cool periods
The activity of the Sun is an important factor in the complex interaction that controls our climate. New research now shows that the impact of the Sun is not constant over time, but has greater significance ...
Map outlines western Oregon landslide risks from a subduction zone earthquake
New landslide maps have been developed that will help the Oregon Department of Transportation determine which coastal roads and bridges in Oregon are most likely to be usable following a major subduction ...
Interaction of Atlantic and Pacific oscillations caused 'false pause' in warming
The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate ...
Drilling ancient African lakes sheds light on human evolution
How was human evolution and migration influenced by past changes in climate?
First direct observation of carbon dioxide's increasing greenhouse effect
Scientists have observed an increase in carbon dioxide's greenhouse effect at the Earth's surface for the first time. The researchers, led by scientists from the US Department of Energy's Lawrence Berkeley ...
Himalayan ice shows chemicals ban is working
A unique study of frozen ice cores from the Tibetan Himalayas has shown that international agreements on phasing out the use of toxic persistent organic pollutants are working.
Geysers have loops in their plumbing: Periodic eruptions tied to underground bends and side-chambers
Geysers like Old Faithful in Yellowstone National Park erupt periodically because of loops or side-chambers in their underground plumbing, according to recent studies by volcanologists at the University of ...
Sea level spiked for 2 years along northeastern North America
Sea levels from New York to Newfoundland jumped up about four inches in 2009 and 2010 because ocean circulation changed, a University of Arizona-led team reports in an upcoming issue of Nature Communications.
Massive amounts of Saharan dust fertilize the Amazon rainforest
The Sahara Desert and the Amazon rainforest seem to inhabit separate worlds. The former is a vast expanse of sand and scrub stretching across the northern third of Africa, while the latter is a dense green ...
Study seeks to understand variations in the rate of global warming
A team of climate scientists, including Professor Mat Collins from the University of Exeter, have investigated the role of internal variability in the Earth's climate system in these periods of slow warming.
A new way to quantify and track soot from its source to destination
No one wants to see dirty snow. But that's just what appears when soot—from forest fires, diesel engines, and other fuel combustion—hitchhikes to the Arctic on atmospheric currents. Researchers at Pacific ...
