• Future Temperature and Soil Moisture May Alter Location of Agricultural Regions

    Future high temperature extremes and soil moisture conditions may cause some regions to become more suitable for rainfed, or non-irrigated, agriculture, while causing other areas to lose suitable farmland, according to a new U.S. Geological Survey study.  

    These future conditions will cause an overall increase in the area suitable to support rainfed agriculture within dryland areas. Increases are projected in North America, western Asia, eastern Asia and South America. In contrast, suitable areas are projected to decline in European dryland areas.

  • Fighting fires before they spark

    With warm, dry summers comes a deadly caveat for the western United States: wildfires. Scientists say the hot, dry climates found west of the Mississippi, along with decades of fire suppression efforts, are creating a devastating and destructive combination – leading to fires like the ones currently burning in California.

  • Study reshapes understanding of climate change's impact on early societies

    A new study linking paleoclimatology — the reconstruction of past global climates — with historical analysis by researchers at Yale and other institutions shows a link between environmental stress and its impact on the economy, political stability, and war-fighting capacity of ancient Egypt.

    The team of researchers examined the hydroclimatic and societal impacts in Egypt of a sequence of tropical and high-latitude volcanic eruptions spanning the past 2,500 years, as known from modern ice-core records. The team focused on the Ptolemaic dynasty of ancient Egypt (305-30 B.C.E.) — a state formed in the aftermath of the campaigns of Alexander the Great, and famed for rulers such as Cleopatra — as well as material and cultural achievements including the great Library and Lighthouse of Alexandria.

  • A New Way to Harness Wasted Methane

    Methane gas, a vast natural resource, is often disposed of through burning, but new research by scientists at MIT could make it easier to capture this gas for use as fuel or a chemical feedstock.

  • Volcanic Eruptions Linked to Social Unrest in Ancient Egypt

    Around 245 BCE Ptolemy III, ruler of the Ptolemaic Kingdom in Egypt, made a decision that still puzzles many historians: After pursuing a successful military campaign against the kingdom’s nemesis, the Seleucid Empire, centred mainly in present-day Syria and Iraq, the king suddenly decided to return home. This about-face “changed everything about Near-East history,” says Joseph Manning, a historian at Yale University.

  • Is It Gonna Blow? Measuring Volcanic Emissions from Space

    Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.

    Late last month, a stratovolcano in Bali named Mount Agung began to smoke. Little earthquakes trembled beneath the mountain. Officials have since evacuated thousands of people to prevent what happened when Agung erupted in 1963, killing more than 1,000 people.

  • NOAA observing buoys validate findings from NASA's new satellite for measuring carbon dioxide

    The strong El Niño event of 2015-2016 provided NASA and NOAA an unprecedented opportunity to test the effectiveness of the newest observation tool to measure global atmospheric carbon dioxide concentrations -- NASA’s Orbiting Carbon Observatory-2 satellite or OCO-2.

    Observations of carbon dioxide concentrations over the tropical Pacific from the satellite were validated by data from NOAA’s Tropical Pacific Observing System of buoys, which directly measure carbon dioxide concentrations at the surface of the ocean.

  • Warming Seas Could Lead to 70 Percent Increase in Hurricane-related Financial Loss

    If oceans warm at a rate predicted by the Intergovernmental Panel on Climate Change, the United Nation-sponsored group that assesses climate change research and issues periodic reports, expected financial losses caused by hurricanes could increase more than 70 percent by 2100, according to a University of Vermont study just published in the journal Sustainable and Resilient Infrastructure.
