Getting warmer? Prehistoric climate can help forecast future changes (11/28/2008)

New data on a prehistoric warm period allow for more accurate predictions of future climate and improved understanding of today's warming. Past warm periods provide real data on climate change and are natural laboratories for understanding the global climate system. Scientists examined fossils from 3.3 to 3.0 million years ago, known as the mid-Pliocene warm period. Research was conducted by the Pliocene Research, Interpretation and Synoptic Mapping group, led by the US Geological Survey. ...> Full Article


Sea level rise alters bay's salinity (11/23/2008)

Sea level rise alters bay's salinityWhile global-warming-induced coastal flooding moves populations inland, the changes in sea level will affect the salinity of estuaries, which influences aquatic life, fishing and recreation. ...> Full Article


Missing radioactivity in ice cores bodes ill for part of Asia (11/21/2008)

Missing radioactivity in ice cores bodes ill for part of AsiaWhen Ohio State glaciologists failed to find the expected radioactive signals in the latest core they drilled from a Himalayan ice field, they knew it meant trouble for their research. But those missing markers of radiation, remnants from atomic bomb tests a half-century ago, foretell much greater threat to the half-billion or more people living downstream of that vast mountain range. ...> Full Article

Forests may play overlooked role in regulating climate (11/20/2008)

In a study to be published next week in the Proceedings of the National Academy of Sciences, scientists led by a team at the University of New Hampshire show that forests may influence the Earth's climate in important ways that have not previously been recognized. ...> Full Article


Glacial erosion changes internal mountain structure, responses to plate tectonics (11/19/2008)

Glacial erosion changes internal mountain structure, responses to plate tectonicsIntense glacial erosion has not only carved the surface of the highest coastal mountain range on earth, the spectacular St. Elias range in Alaska, but has elicited a structural response from deep within the mountain. This interpretation of structural response is based on real-world data now being reported, which supports decades of model simulations of mountain formation and evolution regarding the impact of climate on the distribution of deformation associated with plate tectonics. ...> Full Article

Electronic heat trap grips deep Earth (11/16/2008)

Electronic heat trap grips deep EarthThe key to understanding Earth's evolution, including our atmosphere and how volcanoes and earthquakes form, is to look into the lower mantle, a region some 400 to 1,800 miles below the surface. Researchers at the Carnegie Institution's Geophysical Laboratory simulated conditions at these depths and discovered that the concentration of highly oxidized iron in the two major mantle minerals is key to moving heat in that region and affects material movement throughout the planet. ...> Full Article


Measuring water from space (11/16/2008)

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. ...> Full Article

World needs climate emergency backup plan, says expert (11/8/2008)

In submitted testimony to the British Parliament, climate scientist Ken Caldeira of the Carnegie Institution said that while steep cuts in carbon emissions are essential to stabilizing global climate, there also needs to be a backup plan. Geoengineering solutions such as injecting dust into the atmosphere are risky, but may become necessary if emissions cuts are insufficient to stave off catastrophic warming. He urged that research into the pros and cons of geoengineering be made a high priority. ...> Full Article


Seismic response to natural gas anomalies in crystalline rocks (11/7/2008)

Continental drilling reveals gas anomalies of CH4, CO2, and He in the deep crystalline rocks, which are correlated to the seismic horizontal component reflectors. Geochemical experiments show that porosity of crystalline rocks in the middle crust rose sharply due to water-rock interaction and made natural gas concentration in top of the mid-crust possible, thus resulting in some large gas reservoirs. In such cases, the seismic method can be used to explore these gas reservoirs in the middle crust. ...> Full Article

What is really happening to the Greenland icecap? (11/4/2008)

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. Yet while the southern Greenland ice cap has been melting, it is still not clear how much this is contributing to rising sea levels, and much further research is needed. A framework for such research was defined at a recent workshop organized by the ESF. ...> Full Article
