• Climate change may confuse plant dormancy cycles

    Perennial plants in the Midwest are well attuned to their surroundings. They hunker down all winter in a dormant state, just waiting for a sign that it’s safe to unfurl their first tender leaves or flower buds. For many plants, the cue is a sustained warming trend, but day length also factors into the dormancy equation.

  • NASA-NOAA's Suomi NPP Satellite Takes a Double Look at Tropical Storm Franklin

    When NASA-NOAA’s Suomi NPP satellite passed over Tropical Storm Franklin instruments aboard provided a night-time view of the storm’s clouds and measured their temperatures, revealing a strengthening storm.

    The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard the NASA-NOAA Suomi NPP satellite captured infrared images of Franklin on August 8 at 3:58 a.m. EDT (0758 UTC). The Suomi NPP night-time image showed that Franklin’s northwestern edge had not yet reached San Francisco de Campeche or Merida, as the lights of both cities were still visible in the image. The infrared image provided temperatures of Franklin’s cloud tops, where thunderstorms surrounding the low-level center were as cold as 190 Kelvin (minus 117.7 degrees Fahrenheit / minus 83.1 degrees Celsius). NASA research has shown that storms with cloud top temperatures that cold have the ability to generate very heavy rainfall.

  • NASA's Smartest Satellite Is Gone. Can Private Space Replace It?

    Look down on Buenos Aires from the sky, and you can learn a fair bit about the city. It's got a lot of concrete. Also a lot of trees. There's a bright green river delta to the north, which probably explains the ruddy-brown bay to the east. But with the right camera—a hyperspectral one—you can pick up a whole lot more. New colors emerge, hidden hues your eyes and mine aren't wired to see. And these colors reflect even more detail about the scene: the gases coming out of the city, the health of the plants surrounding it, the species of algae coloring the water offshore.

  • Biochar shows benefits as manure lagoon cover

    Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few.

  • Can Poor Air Quality Mask Global Warming's Effects?

    During the 20th century, the average temperature of the continental United States rose by almost 1 degree Fahrenheit (0.5 degree Celsius) -- everywhere, that is, except in the Southeast.

  • Phytoplankton and chips

    Microbes mediate the global marine cycles of elements, modulating atmospheric carbon dioxide and helping to maintain the oxygen we all breathe, yet there is much about them scientists still don’t understand. Now, an award from the Simons Foundation will give researchers from MIT's Darwin Project access to bigger, better computing resources to model these communities and probe how they work.

    The simulations of plankton populations made by Darwin Project researchers have become increasingly computationally demanding. MIT Professor Michael "Mick" Follows and Principal Research Engineer Christopher Hill, both affiliates of the Darwin Project, were therefore delighted to learn of their recent Simons Foundation award, providing them with enhanced compute infrastructure to help execute the simulations of ocean circulation, biogeochemical cycles, and microbial population dynamics that are the bread and butter of their research.

  • Great Lakes scientists identify research challenges

    The Great Lakes could be in hot water if the quality of the research and partnerships are not improved, warns a University of Windsor professor.

    “Fresh water is arguably the most important issue for the world going forward to support the planet,” said University of Windsor professor Aaron Fisk, the Tier 1 Canada Research Chair in Changing Great Lakes Ecosystems. “But the amount of resources that are dedicated to the Great Lakes from the U.S. and Canada is only a fraction of what is funded for the oceans.”

  • Not all Glaciers in Antarctica Have Been Affected by Climate Change

    A new study by scientists at Portland State University and the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder has found that the effects of climate change, which are apparent in other parts of the Antarctic continent, are not yet observed for glaciers in the western Ross Sea coast.

    Published online ahead of print for the journal Geology, the study found that the pattern of glacier advance and retreat has not changed along the western Ross Sea coast, in contrast to the rapidly shrinking glaciers on the Antarctic Peninsula.
