  • Understanding Arctic Ocean's carbon cycle
    Scientists have conducted a new study to measure levels of carbon at various depths in the Arctic Ocean. The study provides data that will help researchers better understand the Arctic Ocean's carbon cycle -- the pathway through which carbon enters and is used by the marine ecosystem.

  • From lemons to lemonade: Using carbon dioxide to make carbon nitride
    Scientists have discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it creates some useful compounds to boot.

  • Latest Southern Ocean research shows continuing deep ocean change
    There has been a massive reduction in the amount of Antarctic bottom water found off the coast of Antarctica, new research shows.

  • Dry lands getting drier, wet getting wetter: Earth's water cycle intensifying with atmospheric warming
    A clear change in salinity has been detected in the world's oceans, signaling shifts and an acceleration in the global rainfall and evaporation cycle. The patterns are not uniform, with regional variations agreeing with the 'rich get richer' mechanism, where wet regions get wetter and dry regions drier.

  • Toxic mercury, accumulating in the Arctic, springs from a hidden source
    Environmental scientists have discovered that the Arctic accumulation of mercury, a toxic element, is caused by both atmospheric forces and the flow of circumpolar rivers that carry the element north into the Arctic Ocean. While the atmospheric source was previously recognized, it now appears that twice as much mercury actually comes from the rivers. The revelation implies that concentrations of the toxin may further increase as climate change continues to modify the region's hydrological cycle and release mercury from warming Arctic soils.

  • Pollution teams with thunderclouds to warm atmosphere
    New simulation study shows that atmosphere warms when pollution intensifies storms. How much the warming effect of these clouds offsets the cooling that other clouds provide is not yet clear.

  • 1,000 years of climate data confirms Australia's warming
    In the first study of its kind in Australasia, scientists have used 27 natural climate records to create the first large-scale temperature reconstruction for the region over the last 1,000 years.

  • Humanmade pollutants may be driving Earth's tropical belt expansion: May impact large-scale atmospheric circulation
    Black carbon aerosols and tropospheric ozone, both humanmade pollutants emitted predominantly in the Northern Hemisphere's low- to mid-latitudes, are most likely pushing the boundary of the tropics further poleward in that hemisphere, new research shows. While stratospheric ozone depletion has already been shown to be the primary driver of the expansion of the tropics in the Southern Hemisphere, the researchers are the first to report that black carbon and tropospheric ozone are the most likely primary drivers of the tropical expansion observed in the Northern Hemisphere.

  • Ancient tree-ring records from southwest U.S. suggest today's megafires are truly unusual
    Today's mega forest fires of the southwestern U.S. are truly unusual and exceptional in the long-term record, suggests an unprecedented study that examined 1,500 years of ancient tree ring and fire data from two distinct climate periods. Researchers constructed and analyzed a statistical model and found that today's dry, hot climate combined with the past century of human fire suppression is causing megafires.

  • Statistical analysis projects future temperatures in North America
    For the first time, researchers have been able to combine different climate models using spatial statistics -- to project future seasonal temperature changes in regions across North America.

  • Arctic seabirds adapt to climate change
    The planet is warming up, especially at the poles. How do organisms react to this rise in temperatures? Biologists have now shown that little auks, the most common seabirds in the Arctic, are adapting their fishing behavior to warming surface waters in the Greenland Sea. So far, their reproductive and survival rates have not been affected. However, further warming could threaten the species.

  • Measuring CO2 to fight global warming, enforce future treaty
    If the world's nations ever sign a treaty to limit emissions of climate-warming carbon dioxide gas, there may be a way to help verify compliance. Using measurements from only three carbon-dioxide (monitoring stations in the Salt Lake Valley, the method could reliably detect changes in CO2 emissions of 15 percent or more, researchers report.

  • Time, place and how wood is used are factors in carbon emissions from deforestation
    A new study holds implications for the impact of biofuels production on deforestation and greenhouse gas emissions. The volume of greenhouse gas released when a forest is cleared depends on how the trees will be used and in which part of the world the trees are grown.

  • Wasted milk is a real drain on our resources, study shows
    Milk poured down Britain's kitchen sinks each year creates a carbon footprint equivalent to thousands of car exhaust emissions, research shows.

  • NASA's new carbon-counting instrument leaves the nest
    Its construction now complete, the science instrument that is the heart of NASA's Orbiting Carbon Observatory-2 (OCO-2) spacecraft -- NASA's first mission dedicated to studying atmospheric carbon dioxide -- has left its nest at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and has arrived at its integration and test site in Gilbert, Ariz.
