• Extreme weather has greater impact on nature than assumed

    An oystercatcher nest is washed away in a storm surge. Australian passerine birds die during a heatwave. A late frost in their breeding area kills off a group of American cliff swallows. Small tragedies that may seem unrelated, but point to the underlying long-term impact of extreme climatic events. In the special June issue of Philosophical Transactions of the Royal Society B researchers of the Netherlands Institute of Ecology (NIOO-KNAW) launch a new approach to these 'extreme' studies.

  • Varied increases in extreme rainfall with global warming

    A new study by researchers from MIT and the Swiss Federal Institute of Technology in Zurich shows that the most extreme rain events in most regions of the world will increase in intensity by 3 to 15 percent, depending on region, for every degree Celsius that the planet warms.

  • Wild Weather and Climate Change: Scientists Are Unraveling the Links

    Southeast Australia just had its hottest summer on record: temperatures in some areas hit 35 degrees C (95 degrees F) more than 50 days in a row. And climate change, researchers with the World Weather Attribution project have been able to say, was probably to blame. Average temperatures like those in the 2016/17 Australian summer are now 50 times more likely than before global warming began.

  • Migratory birds bumped off schedule as climate change shifts spring

    New research shows climate change is altering the delicate seasonal clock that North American migratory songbirds rely on to successfully mate and raise healthy offspring, setting in motion a domino effect that could threaten the survival of many familiar backyard bird species.

  • Understanding changes in extreme precipitation

    Most climate scientists agree that heavy rainfall will become even more extreme and frequent in a warmer climate. This is because warm air can hold more moisture than cold air, resulting in heavier rainfall.

    However, the involved mechanisms are complex and the increase in extreme precipitation varies in space, as noted by Stephan Pfahl, climate scientist at ETH Zurich and lead author of a paper just published in the journal Nature Climate Change: “The level of atmospheric moisture is just one factor influencing the distribution and intensity of extreme precipitation. Other factors also play a key role – especially when it comes to regional variability.”

  • Research finds spike in dust storms in American Southwest driven by ocean changes

    People living in the American Southwest have experienced a dramatic increase in windblown dust storms in the last two decades, likely driven by large-scale changes in sea surface temperature in the Pacific Ocean drying the region’s soil, according to new NOAA-led research.

    With the increase in dust storms, scientists have also documented a spike in Valley fever, an infectious disease caught by inhaling a soil-dwelling fungus found primarily in the Southwest.

  • In Measuring Gas Exchange Between Water and Air, Size Matters

    Ponds and lakes play a significant role in the global carbon cycle, and are often net emitters of carbon gases to the atmosphere.  However, the rate at which gases move across the air-water boundary is not well quantified, particularly for small ponds.

  • UN agricultural agency links food security and climate change in new guidelines

    The United Nations agricultural agency today unveiled guidelines to help Governments balance the needs of farming and climate change when making decisions, such as whether to refill a dried up lake or focus instead on sustainably using the forest on its shore.

  • Migratory Seabird Deaths Linked to Hurricanes

    Stronger and more frequent hurricanes may pose a new threat to the sooty tern, an iconic species of migratory seabird found throughout the Caribbean and Mid-Atlantic, a new Duke University-led study reveals.

    The study, published this week in the peer-reviewed open-access journal PeerJ, is the first to map the birds’ annual migratory path and demonstrate how its timing and trajectory place them in the direct path of hurricanes moving into the Caribbean after forming over the Atlantic.

    “The route the birds take and that most Atlantic-forming hurricanes take is basically the same – only in reverse,” said Ryan Huang, a doctoral student at Duke’s Nicholas School of the Environment, who led the study. “That means these birds, who are usually very tired from traveling long distances over water without rest, are flying head-on into some of the strongest winds on the planet.”
