  • Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought
    on March 22, 2018 at 7:03 pm

    The existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk. New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought. […]

  • Half a degree more global warming could flood out 5 million more people
    on March 15, 2018 at 3:06 pm

    A new study finds that by 2150, the seemingly small difference between a global temperature increase of 1.5 and 2.0 degrees Celsius would mean the permanent inundation of lands currently home to about 5 million people, including 60,000 who live on small island nations. […]

  • Climate change risk for half of plant and animal species in biodiversity hotspots
    on March 14, 2018 at 2:55 am

    Up to half of plant and animal species in the world's most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked. Even if the Paris Climate Agreement 2°C target is met, these places could lose 25 percent of their species. Researchers examined the impact of climate change on nearly 80,000 plant and animal species in 35 areas. […]

  • A starfish cold case reopens, climate change remains suspect
    on March 13, 2018 at 7:21 pm

    As ocean temperatures rise and oceanic diseases proliferate, species like sea stars struggle to survive, and scientists are looking for underlying causes. To bring clarity to the sea star disease problem, the scientists propose a new, broad nomenclature. […]

  • No laughing matter, yet humor inspires climate change activism
    on March 1, 2018 at 8:15 pm

    Melting icecaps, mass flooding, megadroughts and erratic weather are no laughing matter. However, a new study shows that humor can be an effective means to inspire young people to pursue climate change activism. At the same time, fear proves to be an equally effective motivator and has the added advantage of increasing people's awareness of climate change's risks. […]

  • Scientists discover key gene for producing marine molecule with huge environmental impacts
    on February 26, 2018 at 5:26 pm

    Researchers have discovered a key gene for the synthesis of one of the world's most abundant sulfur molecules -- Dimethylsulfoniopropionate (DMSP). DMSP is an important nutrient in marine environments with more than one billion tonnes produced annually by marine phytoplankton, seaweed and bacteria. The discovery represents a huge step forward in the field of sulfur cycling in marine environments. It could also allow scientists to better predict the impact of climate change on DMSP production. […]

  • Land use change has warmed Earth's surface
    on February 20, 2018 at 7:35 pm

    Recent changes to vegetation cover are causing Earth's surface to heat up. Activities like cutting down evergreen forests for agricultural expansion in the tropics create energy imbalances that lead to higher local surface temperatures and contribute to global warming. […]

  • Sea-level legacy: 20 cm more rise by 2300 for each 5-year delay in peaking emissions
    on February 20, 2018 at 5:30 pm

    Peaking global carbon dioxide emissions as soon as possible is crucial for limiting the risks of sea-level rise, even if global warming is limited to well below 2 degrees C. A new study analyzes for the first time the sea-level legacy until 2300 within the constraints of the Paris Agreement. […]

  • New fuel standards will decrease childhood asthma cases

  • A good life for all within the planet's means
    on February 5, 2018 at 4:31 pm

    A new study has found that no country currently meets its citizens' basic needs at a globally sustainable level of resource use. The research is the first to quantify the sustainability of national resource use associated with meeting basic human needs for 151 countries. […]

  • Ecuador: Deforestation destroys more dry forest than climate change
    on February 2, 2018 at 4:26 pm

    Tropical forests worldwide are at risk. Two of the main threats are the deforestation for arable land and climate change. Scientists compared the losses due to deforestation with those that would result in extreme climate change scenarios in Ecuador. Although global warming is likely to change the distribution of species, deforestation will result in the loss of more dry forests than predicted by climate change damage. […]

  • Better predicting mountains' flora and fauna in a changing world
    on January 23, 2018 at 3:20 pm

    Climbing a mountain is challenging. So, too, is providing the best possible information to plan for climate change's impact on mountain vegetation and wildlife. Scientists show that using several sources of climate measurements when modeling the potential future distributions of mountain vegetation and wildlife can increase confidence in the model results and provide useful guidance for conservation planning. […]

  • Recent advances in understanding coral resilience are essential to safeguard coral reefs
    on January 18, 2018 at 7:19 pm

    The most urgent course of action to safeguard coral reefs is to reduce global greenhouse gas emissions, but concurrently there is also a need to consider novel management techniques and previously over-looked reef areas for protective actions under predicted climate change impacts. The conclusions were reached following a comprehensive review of the literature on the mechanisms of potential coral resistance and recovery across scales from global reef areas to the microbial level within individual corals. […]

  • Researchers explore psychological effects of climate change
    on January 17, 2018 at 9:40 pm

    While some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet's animals and plants experiencing the most stress. […]

  • Future climate change revealed by current climate variations
    on January 17, 2018 at 6:11 pm

  • Adaptation now: River flood risks increase around the globe under future warming
    on January 10, 2018 at 7:13 pm

    Rainfall changes caused by global warming will increase river flood risks across the globe. Already today, fluvial floods are among the most common and devastating natural disasters. Scientists have now calculated the required increase in flood protection until the 2040s worldwide, breaking it down to single regions and cities. They find that the need for adaptation is greatest in the US, parts of India and Africa, Indonesia, and in Central Europe including Germany. Inaction would expose many millions of people to severe flooding. […]

  • The ocean is losing its breath -- here's the global scope
    on January 4, 2018 at 8:35 pm

    In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies, including estuaries and seas, low-oxygen sites have increased more than tenfold since 1950. Scientists expect oxygen to continue dropping even outside these zones as Earth warms. […]
