  • Jet stream changes since 1960s linked to more extreme weather
    on January 12, 2018 at 2:12 pm

    Increased fluctuations in the path of the North Atlantic jet stream since the 1960s coincide with more extreme weather events in Europe such as heat waves, wildfires and flooding. The new research is the first reconstruction of historical changes in the North Atlantic jet stream prior to the 20th century. By using tree rings, the researchers developed a historical look at the position of the North Atlantic jet back to 1725. […]

  • Study predicts a significantly drier world at 2ºC
    on January 1, 2018 at 7:47 pm

    New research predicts a significantly drier world if global warming reaches 2ºC. Over a quarter of the world's land could become significantly drier and the change would cause an increased threat of drought and wildfires. Limiting warming to under 1.5ºC would dramatically reduce the fraction of the Earth's surface that undergoes such changes. Areas which would most benefit from keeping warming below 1.5ºC include Central America, Southern Europe, Southern Australia, parts of South East Asia, and Southern Africa. […]

  • Climate change: Soil animals cannot explain self-reinforcing effect
    on December 21, 2017 at 3:13 pm

    When the soil warms up, it releases more carbon dioxide (CO2) -- an effect that further fuels climate change. Until now, it had been assumed that the reason for this was mainly due to the presence of small soil animals and microorganisms that would eat and breathe more in warmer temperatures. However, a new study has shown that this is not the case. Quite the contrary: If warmth is accompanied by drought, the soil animals eat even less. […]

  • Life on the edge prepares plants for climate change
    on December 19, 2017 at 6:36 pm

  • One wet winter can shake up San Francisco Bay's invasive species
    on December 7, 2017 at 5:59 pm

    For many Californians, last year's wet winter triggered a case of whiplash. After five years of drought, rain from October 2016 to February 2017 broke more than a century of records. In San Francisco Bay, biologists discovered a hidden side effect: All that freshwater rain can turn the tables on some of the bay's invasive species. […]

  • Forests are the key to fresh water
    on December 7, 2017 at 2:50 pm

  • To address hunger effectively, first check the weather, says new study
    on November 24, 2017 at 1:43 pm

    Understanding the climate context is important is determining how to best respond to food insecurity, according to a study of nearly 2,000 smallholder farms in Africa and Asia. Rainfall patterns determined whether financial supports or agricultural inputs or practices were the most effective intervention. […]

  • Flamingo feces and their way of walking stimulate organic matter filtering in saline wetlands
    on November 23, 2017 at 2:52 pm

    The greater flamingo (Phoenicopterus roseus) facilitates microbial ‘filtering’ of organic matter in saline wetlands, thus improving water quality and reducing nitrogen loads by promoting denitrification, research concludes. This is a facilitating role these animals possess which was unknown until now. […]

  • Could we predict La Niña drought years in advance?
    on November 16, 2017 at 4:42 pm

    Scientists' ability to predict the strength and duration of droughts caused by La Niña -- a recurrent cooling pattern in the tropical Pacific Ocean -- has been significantly improved thanks to new research. Their findings, which predict that the current La Niña is likely to stretch into a second year, could help scientists know years in advance how a particular La Niña event is expected to evolve. […]

  • Drought: A cause of riots
    on September 26, 2017 at 1:05 pm

    The scientific community has been working on the possibility of a relationship between periods of drought and rioting for several years. Now a team has formally verified this hypothesis by studying almost 1,800 riots that occurred over a 20-year period in sub-Saharan Africa. The researchers observed a systematic link between the sudden depletion of water resources and the outbreak of unrest. They also succeeded in quantifying the impact of geographic and social factors on the same link. […]

  • Climate insurance is rarely well thought out in agriculture
    on September 25, 2017 at 3:33 pm

    Internationally subsidised agricultural insurance is intended to protect farmers in developing countries from the effects of climate change. However, it can also lead to undesirable ecological and social side effects, as researchers have now explained. Their article also contains recommendations for improved insurance schemes which in future should also take account of ecological and social aspects in addition to economic issues. […]
