Earth & Climate News -- ScienceDaily
  1. Could ‘The Day After Tomorrow’ happen?
    A researcher has produced a scientific study of the climate scenario featured in the disaster movie 'The Day After Tomorrow'. In the 2004 film, climate warming caused an abrupt collapse of the Atlantic meridional overturning circulation (AMOC), leading to catastrophic events such as tornadoes destroying Los Angeles, New York being flooded and the northern hemisphere freezing. Although the scientific credibility of the film drew criticism from climate scientists, the scenario of an abrupt collapse of the AMOC, as a consequence of anthropogenic greenhouse warming, was never assessed with a state-of-the-art climate model.Now scientists have found that, for a period of 20 years, the earth will cool instead of warm if global warming and a collapse of the AMOC occur simultaneously.
  2. Unexpected information about Earth's climate history from Yellow River sediment
    By meticulously examining sediments in China's Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten.
  3. Greenland's ice sheet plumbing system revealed
    Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet. A team of experts has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011.
  4. Sea turtles face plastic pollution peril
    A new global review that set out to investigate the hazards of marine plastic pollution has warned that all seven species of marine turtles can ingest or become entangled in the discarded debris that currently litters the oceans.
  5. Fracking industry wells associated with premature birth
    Expectant mothers who live near active natural gas wells operated by the fracking industry in Pennsylvania are at an increased risk of giving birth prematurely and for having high-risk pregnancies, new research suggests.
  6. Waste water treatment plants fail to completely eliminate new chemical compounds
    Fish caught near waste water plants display a higher rate of endocrine disruptors, researchers have found. Deformities, feminization and fall in reproductive capacity are some of the effects that living organisms can be afflicted by due to changes in the endocrine system caused by these compounds.
  7. NOAA declares third ever global coral bleaching event
    As record ocean temperatures cause widespread coral bleaching across Hawaii, scientists confirm the same stressful conditions are expanding to the Caribbean and may last into the new year, prompting the declaration of the third global coral bleaching event ever on record.
  8. New emergency alert technology could fine-tune warnings for smartphones
    In support of the Department of Homeland Security (DHS), researchers have developed a concept for a more accurate method of delivering certain types of messages that could even warn users to avoid particular nearby locations.
  9. Unexpected role of electrons in creating pulsating auroras
    Thanks to a lucky conjunction of two satellites, a ground-based array of all-sky cameras, and some spectacular aurora borealis, researchers have uncovered evidence for an unexpected role that electrons have in creating the dancing auroras. Though humans have been seeing auroras for thousands of years, we have only recently begun to understand what causes them.
  10. Hundreds of new species discovered in fragile Eastern Himalayan region
    A sneezing monkey, a walking fish and a jewel-like snake are just some of a biological treasure trove of over 200 new species discovered in the Eastern Himalayas in recent years, according to a new report by WWF.
