  • Slowing economy doesn't slow greenhouse emissions
    Monday, June 13, 2011

    PRESCOTT - When a University of Arizona climate scientist displayed a chart Saturday showing an exponential increase in greenhouse gas concentrations in the Earth's atmosphere over the past 150 years, his Prescott audience emitted a collective gasp.

    Michael Crimmins, an assistant professor at UofA and Extension Office climate science specialist, first displayed a relatively flat line showing greenhouse gas emissions over a 10,000-year time...

  • UA tree ring research offers hope for wet monsoon season
    Sunday, June 12, 2011

    What if the summer rains don't arrive to drench our desiccated deserts, forests and front lawns?

    It has happened before, although it is not the prediction for this year, nor the normal pattern.

    Wet summers usually follow dry winters.

    Atmospheric scientists trace that to the cooling and warming of the Pacific Ocean - the phenomena known as La Niña and El Niño.

    In a La Niña year, when Pacific temperatures cool, winter rains are...

  • Before Reality TV, Life in an Actual Bubble
    Saturday, June 11, 2011

    The desert vista here is stunning, with saguaro cactuses and rugged hills as far as the eye can see, if only someone would spray some Windex on the glass.

    Long before contestants on “Survivor” were plopped into challenging spots to outscheme and outlast one another, there was Biosphere 2.

    In the early 1990s, two successive groups were sealed inside a giant steel and glass bulb north of Tucson to test their survivability. It was part serious science, with...

  • Snowpack Declines in Rockies Unusual Compared to Past
    Thursday, June 9, 2011

    The researchers evaluated the recent declines using snowpack reconstructions from 66 tree-ring chronologies, looking back 500 to more than 1,000 years.

    The reduction in snowpack in the Rocky Mountains over the last 30 years is unusual compared to the past few centuries, according to a new study that includes University of Arizona researchers.

    Previous studies attribute the decline to unusual springtime warming, more precipitation falling now as rain rather than snow and...

  • What Would Happen If Earth and Mars Switched Places?
    Thursday, June 9, 2011

    Last Saturday, at a workshop organized by the Foundation Questions Institute, Nobel laureate physicist Gerard 't Hooft gave a few informal remarks on the deep nature of reality. Searching for an analogy to the symmetries of basic physics, he asked the attendees to imagine what would happen to our solar system if you suddenly swapped Earth and Mars. He went on to discuss his ideas for explaining quantum mechanics, but I couldn't get my mind off his...

  • Monster wildfire in Arizona: A glimpse of what climate change could bring
    Thursday, June 9, 2011

    Even as the Wallow fire threatens to alter the Arizona landscape for a long time to come, some scientists say climate change may be fueling a trend toward larger wildfires in the American West.

    A wildfire in Arizona that has blackened an area half the size of Rhode Island, prompted the evacuation of some 2,000 people in its path, and is...
