Pine Bark Beetles Affecting More than Forests
Pine bark beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality. view more (2008-09-25)
Record air pollution above the Arctic
Last week Scientists of the Alfred Wegener Institute for Polar and Marine Research observed the highest air pollution on record since measurements began in Ny-Ã-lesund on Svalbard. Monitoring instruments displayed significantly increased aerosol concentrations compared to those generally found. view more (2006-05-11)
Incentives for carbon sequestration may not protect species
Paying rural landowners in Oregon's Willamette Basin to protect at-risk animals won't necessarily mean that their newly conserved trees and plants will absorb more carbon from the atmosphere and vice versa, a new study has found. view more (2008-07-08)
Scientist proposes explanation for puzzling property of night-shining clouds at the edge of space
An explanation for a strange property of noctilucent clouds--thin, wispy clouds hovering at the edge of space at 85 km altitude--has been proposed by an experimental plasma physicist at the California Institute of Technology (Caltech), possibly laying to rest a decades-long mystery. view more (2008-09-26)
Clouds: Lighter than air but laden with lead
By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds. view more (2009-04-20)
Arizona State scientists keep an eye on Martian dust storm
Scientists at Arizona State University's Mars Space Flight Center are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a large dust storm on the Red Planet. view more (2007-07-12)
Space shuttle science shows how 1908 Tunguska explosion was caused by a comet
The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth's atmosphere, says new Cornell University research. view more (2009-06-25)
Ancient Oak Trees Help Reduce Global Warming, MU Study Finds
The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in freshwater aquatic systems store carbon for... view more... (2008-06-30)
New research confirms increased greening
Greening seems to have increased during the 1980s and 1990s in the northern hemisphere from the arctic regions down to the 35th parallel of latitude (roughly southern Europe). This has been shown by measurements from space satellites. Some observers, however, have doubted the reliability of these measurements. In the latest issue of Science, a... view more... (2002-06-04)
Scientists Find Good News About Methane Bubbling Up From the Ocean Floor Near Santa Barbara
Methane, a potent greenhouse gas, is emitted in great quantities as bubbles from seeps on the ocean floor near Santa Barbara. view more (2007-12-21)
Preparing for the Venus Express
The European Space Agency is planning its first mission to unveil the mysteries of Earth`s cloud-shrouded sister planet, Venus. On Wednesday 10 April, Professor Fred Taylor (University of Oxford) will be explaining to the UK National Astronomy Meeting why European scientists are hoping to be on board the Venus Express in 2005. Venus, the Earth`s... view more... (2002-04-03)
NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years. view more (2005-12-07)
Does life exist on other planets?
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. view more (2005-06-20)
Old growth forests are valuable carbon sinks
Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries. view more (2008-09-11)
Explaining the methane mystery
Scientists have explained why atmospheric levels of the greenhouse gas methane have stabilised in recent years, but warn that increases could resume in the near future. view more (2006-09-28)
Gas escaping from ocean floor may drive global warming
Gas escaping from the ocean floor may provide some answers to understanding historical global warming cycles and provide information on current climate changes. view more (2006-07-20)
Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
Permafrost - the perpetually frozen foundation of North America - isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. view more (2007-08-10)
Micro-organisms in salt lakes produce chlorinated air pollutants - Discovery of a new natural factor in desertification: Micro-organisms in salt lakes.
Salt lakes have a greater impact on climate change than was previously understood. This has been established by scientists from the UFZ Centre for Environmental Research (Umweltforschungszentrum Leipzig-Halle) together with colleagues from Austria, Russia and South Africa. They found evidence that bacteria in salt lakes produce substances which... view more... (2005-02-25)
Study shows our ancestors survived 'Snowball Earth'
It has been 2.3 billion years since Earth's atmosphere became infused with enough oxygen to support life as we know it. About the same time, the planet became encased in ice that some scientists speculate was more than a half-mile deep. view more (2006-06-07)
Plants' role in global warming re-examined in ORNL Science paper
Estimates of increased plant respiration in response to higher global temperatures may be somewhat overstated as they have not taken into account plants' ability to adjust to changing conditions, according to researchers from Oak Ridge National Laboratory. view more (2006-05-02)
