  4. Scientists Search for Answers from the Carbon in the Clouds July 25, 2008

    For scientists looking at climate change, a large area of uncertainty has to do with the effects of airborne particles – such as carbon-laden soot – but new technology is now helping researchers unveil secrets about the life cycles of atmospheric aerosols. (Boston College press release)

  5. Typhoons Bury Tons of Carbon in the Oceans July 23, 2008

    A single typhoon in Taiwan buries as much carbon in the ocean – in the form of sediment – as a combined year's worth of rains in that country, according to an Ohio State University study published in a recent issue of the journal Geology. (Ohio State University press release)

  6. Amazon Outflow is Found to Power Ocean Capture of Carbon Dioxide July 23, 2008

    Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study. (The Earth Institute at Columbia University press release)

  7. Unique Fossil Discovery Shows Antarctic was Once Much Warmer July 23, 2008

    A new fossil discovery – the first of its kind from the whole of the Antarctic continent – provides scientists with new evidence to support the theory that the polar region was once much warmer. (University of Leicester press release)

  8. Scientists Offer New Explanation for Monsoon Development July 21, 2008

    Geoscientists have come up with a new explanation for the formation of monsoons, proposing an overhaul of a theory about the cause of the seasonal pattern of heavy winds and rainfall that essentially had held firm for more than 300 years. (California Institute of Technology press release)

  9. Chinese Earthquake Provides Lessons for Future July 21, 2008

    The May 12 Sichuan earthquake in China was unexpectedly large, but topographic analysis can help evaluate other, similar fault areas for seismic risk, according to geologists. (Pennsylvania State University press release)

  10. Saharan Dust Storms Sustain Life in Atlantic Ocean July 18, 2008

    Research at the University of Liverpool has found how Saharan dust storms help sustain life over extensive regions of the North Atlantic Ocean. (University of Liverpool press release)

  11. Iceberg Scour Affects Biodiversity July 17, 2008

    Antarctic worms, sea spiders, urchins and other marine creatures living in near-shore shallow habitats are regularly pounded by icebergs, and new data suggests this environment along the Antarctic Peninsula is going to get hit more frequently. (British Antarctic Survey press release)

  12. Scientists Demonstrate the Sharpest Measurement of Ice Crystals in Clouds July 17, 2008

    Scientists have created an instrument designed to help determine the shapes and sizes of tiny ice crystals typical of those found in high-altitude clouds, down to the micron level, and data produced using this instrument will likely help improve computer models used to predict climate change. (Optical Society of America press release)

  13. Undersea Volcanoes Triggered Marine Extinction July 16, 2008

    The answer to mass extinction of animals and plants 93 million years ago has been found at the bottom of the sea floor where lava fountains erupted, altering the chemistry of the sea and possibly of the atmosphere, new research suggests. (University of Alberta press release)

  14. For Toy-Like NASA Robots in Arctic, Ice Research is Child's Play July 15, 2008

    SnoMotes are the first prototype network of their kind envisioned to rove treacherous areas of the Arctic and Antarctic.

  15. Scientists Close in on Source of X-rays in Lightning July 15, 2008

    University of Florida and Florida Institute of Technology engineering researchers have narrowed the search for the source of X-rays emitted by lightning, a feat that could one day help predict where lightning will strike. (University of Florida press release)

  16. Future Snowmelt in West Twice as Early as Expected July 15, 2008

    Global warming could lead to larger changes in snowmelt in the western United States than was previously thought, possibly increasing wildfire risk and creating new water management challenges for agriculture, ecosystems and urban populations. (Purdue University press release)

  17. Icelandic Volcanoes Help Researchers Understand Potential Effects of Eruptions July 14, 2008

    For the first time, researchers have taken a detailed look at what lies beneath all of Iceland's volcanoes – and have found a world far more complex than they ever imagined. (Ohio State University press release)

  18. Scattered Nature of Wisconsin's Woodlands Could Complicate Forests' Response to Climate Change July 14, 2008

    If a warmer Wisconsin climate causes some northern tree species to disappear in the future, it's easy to imagine that southern species will just expand their range northward as soon as the conditions suit them. (University of Wisconsin-Madison press release)

  19. One-Third of Reef-Building Corals Face Extinction July 10, 2008

    A third of reef-building corals around the world are threatened with extinction, according to the first-ever comprehensive global assessment to determine their conservation status. (Conservation International press release)

  20. Projected California Warming Promises Cycle of More Heat Waves, Energy Use for Next Century July 10, 2008

  23. Human Influences Challenge Penguin Populations July 1, 2008

    Pronounced warming in the Antarctic, as well as commercial fishing, mining, and oil and gas development at lower latitudes, has led to declines in many species, including the Galápagos, Peruvian, and African species of penguin, according to scientists.
