A research work of the University of Granada, Spain, in the Andalusian Center for Environmental Studies, has studied with an advanced technique the role of the atmospheric aerosol to produce global warming or cooling. This study represents the development of the first systematic application of the Lidar Raman technique in a Spanish station. The developed methodologies and proceedings will be systematically used in the climatic characterization of the atmospheric aerosol over the Southern Iberian Peninsula.

While a total or partial collapse of the West Antarctic Ice Sheet as a result of warming would not raise global sea levels as high as some predict, levels on the US seaboards would rise 25 percent more than the global average and threaten cities like New York, Washington, D.C., and San Francisco, according to a new study.

Earth's earliest ice ages may have been due to the rise of oxygen in Earth's atmosphere, which consumed atmospheric greenhouse gases and chilled the earth. Alan J. Kaufman, professor of geology at the University of Maryland, Maryland colleague James Farquhar, and a team of scientists from Germany, South Africa, Canada, and the US, uncovered evidence that the oxygenation of Earth's atmosphere coincided with the first widespread ice age on the planet.

 | Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise according to a report in the journal Geology this month. ...> Full Article |
 | The Yucca Mountain crest in Nevada, USA has been proposed as a permanent site for high level radioactive waste. But a new study, already published as an article in press by Elsevier's journal Geomorphology and recently included in the research highlights of Nature, shows that there may be erosion of the crest. ...> Full Article |
Geoscientists are gathering for the 105th Annual Meeting of the Cordilleran Section of the Geological Society of America, being held May 7-9, 2009 in Kelowna, British Columbia, Canada. The Earth and Environmental Sciences Program at the University of British Columbia-Okanagan is hosting the meeting. The technical program, presented by academic and industry scientists, and graduate and undergraduate students, will highlight cutting-edge scientific research in themed and general discipline sessions.

 | The Integrated Ocean Drilling Program drillship JOIDES Resolution is returning to port in Honolulu this week after a two-month voyage to chart detailed climate history in the equatorial Pacific Ocean. The expedition was the first of two back-to-back voyages of a scientific project called Pacific Equatorial Age Transect. It was the first international scientific drilling expedition after the JOIDES Resolution underwent a multiyear transformation into a 21st-century floating science laboratory. ...> Full Article |
 | This GSA Special Paper focuses on the catastrophic events that have influenced both Mars and Earth and is part of the ongoing search for the correct balance between catastrophic and uniformitarian processes. The book aims to "expand the geoscience horizons" of a wide range of readers by examining evidence for various geologic catastrophes on both Earth and Mars, their preservation on Earth as compared to Mars, and how these events may have influenced Earth's evolution. ...> Full Article |
