  • Scientists identify three causes of Earth's spin axis drift
    on September 19, 2018 at 11:59 pm

    Using observational and model-based data spanning the entire 20th century, scientists have for the first time have identified three broadly-categorized processes responsible for Earth's spin axis drift -- contemporary mass loss primarily in Greenland, glacial rebound, and mantle convection. […]

  • Unprecedented ice loss in Russian ice cap
    on September 19, 2018 at 6:49 pm

    In the last few years, the Vavilov Ice Cap in the Russian High Arctic has dramatically accelerated, sliding as much as 82 feet a day in 2015, according to a new multi-national, multi-institute study. That dwarfs the ice's previous average speed of about 2 inches per day and has challenged scientists' assumptions about the stability of the cold ice caps dotting Earth's high latitudes. […]

  • How slick water and black shale in fracking combine to produce radioactive waste
    on September 18, 2018 at 7:48 pm

    Study explains how radioactive radium transfers to wastewater in the widely-used method to extract oil and gas. […]

  • Geoscientists find unexpected 'deep creep' near San Andreas, San Jacinto faults
    on September 18, 2018 at 5:17 pm

    A new analysis of thousands of very small earthquakes in the San Bernardino basin suggests that the unusual deformation of some may be due to 'deep creep' 10 km below the Earth's surface, say geoscientists. They say scientists should not use the information recorded by these small earthquakes to predict loading of the nearby San Andreas and San Jacinto faults. […]

  • Geologists reveal ancient connection between England and France
    on September 14, 2018 at 12:48 pm

    The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research. […]

  • Ancient farmers spared us from glaciers but profoundly changed Earth's climate
    on September 6, 2018 at 6:15 pm

    New evidence shows that ancient farming practices led to a rise in the atmospheric emission of the heat-trapping gases carbon dioxide and methane -- a rise that has continued since, unlike the trend at any other time in Earth's geologic history. […]

  • Volcano under ice sheet suggests thickening of West Antarctic ice is short-term
    on September 6, 2018 at 2:04 pm

    Evidence left by a volcano under the ice sheet suggests that the observed bulging of ice in West Antarctica is a short-term feature that may not affect the glacier's motion over the long term. […]

  • Global warming: Worrying lessons from the past
    on September 6, 2018 at 12:21 pm

    Fifty-six million years ago, Earth experienced an exceptional episode of global warming. Within 10,000 to 20,000 years, the average temperature increased by 5 to 8 degrees, only returning to its original level a few hundred thousand years later. Based on the analysis of sediments from the southern slope of the Pyrenees, researchers measured the impact of this warming on river floods and the surrounding landscapes. Their conclusions show that the consequences of such global warming may have been much greater than predicted by current climate models. […]

  • Shining light on ancient global warming
    on September 5, 2018 at 6:20 pm

    The impact of global warming on shallow marine life approximately 56 million years ago is the subject of a significant, new article. Researchers have now addressed the effects of the Paleocene-Eocene Thermal Maximum (PETM) -- a relatively brief period of global climate change, spanning 200,000 years -- on marine invertebrates, including snails, clams and other mollusks. […]

  • Episodic and intense rain caused by ancient global warming
    on September 4, 2018 at 3:46 pm

    on September 4, 2018 at 2:32 pm

    Satellites are more likely to be at risk from high-speed solar wind than a major geomagnetic storm according to a new study. […]

  • New imagery solves mystery of why Mount St. Helens is out of line with other volcanoes
    on September 4, 2018 at 1:38 pm

    Some of the clearest, most comprehensive images of the top several miles of the Earth's crust have helped scientists solve the mystery of why Mount St. Helens is located outside the main line of the Cascade Arc of volcanoes. […]

  • Faster than we thought: Sulfurization of organic material
    on August 30, 2018 at 10:00 pm

    Processes that were thought to take tens of thousands of years can happen in hours, according to new research. And that may change our understanding of the carbon cycle, and maybe the history of Earth's climate. […]

  • Injection wells can induce earthquakes miles away from the well
    on August 30, 2018 at 6:32 pm

    A study of earthquakes induced by injecting fluids deep underground has revealed surprising patterns, suggesting that current recommendations for hydraulic fracturing, wastewater disposal, and geothermal wells may need to be revised. […]

  • Drought, groundwater loss sinks California land at alarming rate
    on August 29, 2018 at 7:38 pm

    The San Joaquin Valley in central California, like many other regions in the western United States, faces drought and ongoing groundwater extraction, happening faster than it can be replenished. And the land is sinking as a result -- by up to a half-meter annually. […]

  • New technique to forecast geomagnetic storms developed
    on August 29, 2018 at 3:54 pm

    Flashes of brightness known as solar flares can be followed by coronal mass ejections that send plasma from the sun into space. These charged particles can then travel to Earth, and when they arrive they wreak havoc on Earth's magnetic field. The result can be beautiful but also destructive: auroras and geomagnetic storms. Researchers now report a method for analyzing magnetic field data that might provide better short-term forecasting of geomagnetic storms. […]

  • Geologists uncover new clues about largest mass extinction ever
    on August 27, 2018 at 4:13 pm

  • New Antarctic rift data has implications for volcanic evolution
    on August 21, 2018 at 1:41 pm

    New marine geophysical data recorded during two excursions on a French icebreaker enabled researchers to date the ocean floor and calculate the relative motion between the Antarctic Plates and the Australian Plate. This new data revealed that Antarctica fused into one plate around 11 million years ago, roughly 15 million years later than previously assumed. […]

  • A timescale for the origin and evolution of all of life on Earth
    on August 20, 2018 at 3:31 pm

  • The bright ways forests affect their environment
    on August 20, 2018 at 3:30 pm

    New study finds volatile gases emitted by forests increase the amount of diffuse light reaching the forests. The study shows that this increased diffuse sunlight enhanced the carbon absorbed by the world's forests by an amount equal to 10 percent of global fossil fuel emissions and industry emissions. […]

  • Study of material surrounding distant stars shows Earth's ingredients 'pretty normal'
    on August 15, 2018 at 11:05 pm

    The Earth's building blocks seem to be built from 'pretty normal' ingredients, according to researchers working with the world's most powerful telescopes. Scientists have measured the compositions of 18 different planetary systems from up to 456 light years away and compared them to ours, and found that many elements are present in similar proportions to those found on Earth. This will have implications for finding Earth-like bodies elsewhere. […]

  • Faster way to make mineral to remove carbon dioxide from atmosphere
    on August 14, 2018 at 8:26 pm

    Scientists have developed an accelerated way to produce magnesite, a mineral which can capture the greenhouse gas carbon dioxide from the atmosphere, at room temperature. Removing carbon dioxide from the atmosphere would slow global warming. This work takes a different approach to existing processes, and may make it economically viable, but it is at an early stage and is not yet an industrial process. […]

  • Melt-rate of West Antarctic Ice Sheet highly sensitive to changes in ocean temperatures
    on August 13, 2018 at 3:35 pm

    Melting of ice shelves in West Antarctica speeds up and slows down in response to changes in deep ocean temperature, and is far more variable than previously thought, according to new research. […]

  • Scientists trace atmospheric rise in CO2 during deglaciation to deep Pacific Ocean
    on August 13, 2018 at 3:33 pm

    How carbon made it out of the ocean and into the atmosphere has remained one of the most important mysteries of science. A new study, provides some of the most compelling evidence for how it happened -- a 'flushing' of the deep Pacific Ocean caused by the acceleration of water circulation patterns that begin around Antarctica.
