  • Arctic wintertime sea ice extent is among lowest on record
    on March 23, 2018 at 6:13 pm

    Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists. […]

  • Significant role for nitrate in the Arctic landscape
    on March 23, 2018 at 5:08 pm

    Because of the very low nitrate levels found in arctic tundra soil, scientists had assumed that plants in this biome do not use nitrate. But a new study challenges this notion. The study has important implications for predicting which arctic plant species will dominate as the climate warms, as well as how much carbon tundra ecosystems can store. […]

  • Germany was covered by glaciers 450,000 years ago
    on March 23, 2018 at 2:48 pm

    Researchers have obtained new chronological data for the timing of the Elsterian and Saalian glacial cycles in central Germany. They found that the first Quaternary glaciation, which covered huge parts of Europe in ice, occurred as early as 450,000 years ago and not - as previously thought - around 350,000 years ago. The researcher further showed that once these glaciers had retreated, the first people appeared in central Germany around 400,000 years ago. […]

  • 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. […]

  • Two-billion-year-old salt rock reveals rise of oxygen in ancient atmosphere
    on March 22, 2018 at 7:03 pm

  • When the Mediteranean Sea flooded human settlements
    on March 22, 2018 at 3:27 pm

    Around 7,600 years ago, the emergence of agricultural settlements in Southeastern Europe and subsequent progress of civilization suddenly came to a standstill. This was most likely caused by an abrupt sea level rise in the northern Aegean Sea. Researchers have now detected evidence of this in the fossils of tiny calcifying marine algae preserved in seafloor sediments. […]

  • Laser-based system offers continuous monitoring of leaks from oil and gas operations
    on March 22, 2018 at 2:32 pm

  • Drought-induced changes in forest composition amplify effects of climate change
    on March 21, 2018 at 7:53 pm

    The face of American forests is changing, due to climate change-induced shifts in rainfall and temperature that are causing shifts in the abundance of numerous tree species, according to a new article. The result means some forests in the eastern U.S. are already starting to look different, but more important, it means the ability of those forests to soak up carbon is being altered as well, which could in turn bring about further climate change. […]

  • US national parks increasingly important for bird conservation in face of climate change
    on March 21, 2018 at 6:14 pm

    US national parks could become even more important for the conservation of bird species in the face of climate change, according to a new study. […]

  • New interactive map shows climate change everywhere in world
    on March 21, 2018 at 4:16 pm

    A geography professor has created a new interactive map that allows students or researchers to compare the climates of places anywhere in the world. The map draws on five decades of public meteorological data recorded from 50,000 international weather stations around the Earth. And it uses prediction models to display which parts of the globe will experience the most or least climate change in the next 50 years. […]

  • 'We're sleepwalking into a mass extinction' say scientists
    on March 21, 2018 at 4:15 pm

    Species that live in symbiosis with others, which often occur in the most delicately balanced and threatened marine ecosystems such as coral reefs, are the slowest to recover their diversity if damaged, according to a team of scientists. […]

  • The environment determines Caribbean hummingbirds' vulnerability
    on March 21, 2018 at 4:15 pm

    Hummingbirds' specialization and vulnerability are often predicted based on their physical traits. Scientists now found that this is not the case for hummingbirds on the Caribbean islands. Instead, the bird's environment is the determining factor. […]

  • Evidence for a giant flood in the central Mediterranean Sea
    on March 21, 2018 at 3:08 pm

    Marine scientists have uncovered evidence of one of the largest floods in Earth's history in the central Mediterranean seafloor. The flood, known as the Zanclean flood, is thought to have ended the Messinian Salinity Crisis (MSC), a period during which the Mediterranean Sea became partially dried up. […]

  • Hunting squid slowed by rising carbon levels
    on March 21, 2018 at 1:47 pm

    Scientists have found that high carbon dioxide levels cause squid to bungle attacks on their prey. Investigators said that the oceans absorb more than one-quarter of all the excess carbon dioxide (CO2) released into the atmosphere by humans and this uptake of additional CO2 causes seawater to become more acidic. […]

  • Pacific influences European weather
    on March 21, 2018 at 1:10 pm

    Sea surface temperature in the distant tropical Pacific can influence November weather in Europe. […]

  • A method for predicting the impact of global warming on disease
    on March 20, 2018 at 6:13 pm

  • Climate change threatens world's largest seagrass carbon stores
    on March 19, 2018 at 8:00 pm

    In the summer of 2010-2011 Western Australia experienced an unprecedented marine heat wave that elevated water temperatures 2-4°C above average for more than 2 months. The heat wave resulted in defoliation of the dominant Amphibolis antarctica seagrass species across the iconic Shark Bay World Heritage Site. Researchers alert us of the major carbon dioxide (CO2) emissions resulting from this loss of seagrass meadows at Shark Bay -- one of the largest remaining seagrass ecosystems on Earth. […]

  • So close, yet so far: Making climate impacts feel nearby may not inspire action
    on March 19, 2018 at 7:57 pm

    An expert says it is possible to make faraway climate impacts feel closer. But that doesn't automatically inspire the American public to express greater support for policies that address it. […]

  • Historians to climate researchers: Let's talk
    on March 19, 2018 at 6:46 pm

    Ours is not the first society to be confronted by massive environmental change. Over the course of history, some societies have been destroyed by natural disasters, like Pompeii, while others have learned how to accommodate floods, droughts, volcanic eruptions and other natural hazards. The key is how a society plans for and interacts with the stress from nature. […]

  • Geoengineering polar glaciers to slow sea-level rise
    on March 19, 2018 at 6:45 pm

    Targeted geoengineering to preserve continental ice sheets deserves serious research and investment, argues an international team of researchers. Without intervention, by 2100 most large coastal cities will face sea levels that are more than three feet higher than they are currently. […]

  • Human influence on climate change will fuel more extreme heat waves in US
    on March 19, 2018 at 4:43 pm

    Human-caused climate change will drive more extreme summer heat waves in the western US, including in California and the Southwest as early as 2020, new research shows. […]

  • Glacier mass loss: Past the point of no return
    on March 19, 2018 at 4:42 pm

    Researchers show in a recent study that the further melting of glaciers cannot be prevented in the current century -- even if all emissions were stopped now. However, due to the slow reaction of glaciers to climate change, our behavior has a massive impact beyond the 21st century: In the long run, five hundred meters by car with a mid-range vehicle will cost one kilogram of glacier ice.
