Earth Sciences

Earth Sciences (also referred to as Geosciences), which deals with basic issues surrounding our planet, plays a vital role in the area of energy and raw materials supply.

Earth Sciences comprises subjects such as geology, geography, geological informatics, paleontology, mineralogy, petrography, crystallography, geophysics, geodesy, glaciology, cartography, photogrammetry, meteorology and seismology, early-warning systems, earthquake research and polar research.

NASA Helps Highlight Lightning Safety Awareness Week

Summertime arrives officially on June 21 in the northern hemisphere, and with it comes thunderstorms. As a result, the National Oceanic and Atmospheric Administration named the week of June 19-25 National Lightning Safety Awareness Week.

NASA encourages summer swimmers, picnickers and others to keep an eye on the sky and stay safe during outdoor activities. NASA lightning expert Dr. Dennis Boccippio, of NASA’s Marshall Space Flight Center (MSFC) in Huntsville, Ala., warn

Shaping the Potential for Global Environmental Governance

Shaping the Potential for Global Environmental Governance
International Global Change Research Conference in Bonn, 9-13-October 2005

Global environmental change has led to increased risks for many and worsened existing inequities, in some cases leading to conflicts. The numbers of environmental refugees are on the rise. Who is responsible for climate change, and who, in turn, suffers most from it? How do individuals and communities cope with environmental stresses, and what i

Concept vehicle unveiled

An innovative concept for an Antarctic vehicle is unveiled this week at the Royal College of Art’s final year show. Working closely with experts from the British Antarctic Survey (BAS), award-winning designer James Moon has come up with a lightweight, compact eco-friendly vehicle for use in one of the Earth’s most extreme environments.

The vehicle, called “Ninety Degrees South”, uses novel technology to keep drivers safe, warm and protected from the high levels UV exposure that occur und

Assessing the Amazon River’s sensitivity to deforestation

Understanding how the Amazon River varies in time, what causes those variations, and how sensitive it will be to ongoing, and accelerating, deforestation is a focus of study for scientists at the Woods Hole Research Center. Population and development pressures in the last several decades have led to significant areas of deforestation in the Amazon, most in the eastern and southern portion of the basin. By using a combination of numerical models and data from several disciplines to assess the poss

Does life exist on other planets?

An atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe

Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist.

Professor David Catling at Bristol University, along with colleagues at the University of Washington and NASA, contend that significant oxygen in the air and o

NCAR climate expert: Hurricanes to intensify as Earth warms

Warmer oceans, more moisture in the atmosphere, and other factors suggest that human-induced climate change will increase hurricane intensity and rainfall, according to climate expert Kevin Trenberth of the National Center for Atmospheric Research. His paper, “Uncertainty in Hurricanes and Global Warming,” appears in the Perspectives section of the June 17 issue of Science.

“Trends in human-influenced environmental changes are now evident in hurricane regions,” says Trenberth. “Th
