  • Gulf of Mexico 'dead zone' forecasted to exceed the size of Connecticut
    on June 7, 2018 at 4:07 pm

    Scientists have predicted the dead zone, or area with little to no oxygen in the northern Gulf of Mexico, will become larger than the state of Connecticut by the end of July, according to a new report. While there are more than 500 dead zones around the world, the northern Gulf of Mexico dead zone is the second largest human-caused coastal hypoxic area in the world. […]

  • Injuries and loss of life boost religious faith after disasters
    on June 5, 2018 at 9:25 pm

    Weather-related disasters can make people more religious but it depends on the toll they inflict, suggests new research. If a disaster injures a significant number of people, it can strengthen religiosity among those who are already religious. But if a disaster inflicts mostly economic damage, the opposite effect applies. […]

  • Storm's coming: New technique for simulation of extreme weather events
    on June 4, 2018 at 3:24 pm

    Scientists have developed a new method for generating data for ensemble simulation of extreme weather phenomena.

  • Huddling for survival: monkeys with more social partners can winter better
    on May 30, 2018 at 3:31 pm

    Wild monkeys which have more social partners form larger huddles in adverse weather and have a better chance of surviving winter, new research has found. The study is the first to show that such social bonding may be connected to higher 'fitness' -- the term used by scientists to measure of how well animals can cope with their local ecological conditions, usually measured by reproductive success and survival. […]

  • Increasing heat is driving off clouds that dampen California wildfires
    on May 30, 2018 at 3:29 pm

    Sunny California may be getting too sunny. Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once common low-lying morning clouds in many southern coastal areas of the state, leading to increased risk of wildfires, says a new study. […]

  • The case of the relativistic particles solved with NASA missions
    on May 29, 2018 at 6:09 pm

    Encircling Earth are two enormous rings -- called the Van Allen radiation belts -- of highly energized ions and electrons. Various processes can accelerate these particles to relativistic speeds, which endanger spacecraft unlucky enough to enter these giant bands of damaging radiation. Scientists had previously identified certain factors that might cause particles in the belts to become highly energized, but they had not known which cause dominates. […]

  • Tree species vital to restoring disturbed tropical forests
    on May 29, 2018 at 5:20 pm

    A family of trees with high drought tolerance could be crucial in restoring the world's deforested and degraded tropical lands, according to new research. […]

  • China floods to hit US economy: Climate effects through trade chains
    on May 28, 2018 at 7:19 pm

    Fluvial floods will increase due to human-made climate change, in particular in China. This might raise direct and indirect economic losses along the global supply and trade chains. The US is susceptible to indirect climate-related economic losses due to its negative trade balance with China. Trump's tariffs might further reduce the resilience of the US economy. […]

  • Tall and older Amazonian forests more resistant to droughts
    on May 28, 2018 at 4:40 pm

    A new study shows that photosynthesis in tall Amazonian forests -- forests above 30m -- is 3x less sensitive to precipitation variability than in shorter forests of less than 20m. Taller Amazonian forests were also found to be older, have more biomass and deeper rooting systems that enable them to access deeper soil moisture, making them more resilient to drought. The findings suggest that forest height + age are an important regulator of photosynthesis in response to droughts. […]

  • New theory finds 'traffic jams' in jet stream cause abnormal weather patterns
    on May 24, 2018 at 6:16 pm

    A study offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it's exceeded, blockages form that are remarkably similar to traffic jams -- and climate forecasters can use the same math to model them both. […]

  • Some desert creatures may be able to cope with climate change better than expected
    on May 24, 2018 at 6:15 pm

    Ecologists have no doubt that climate change will affect the earth's animals and plants. But how exactly? This is often hard to predict. There are already indications that some species are shifting their distribution range. But it is much less clear how individual animals and populations are responding to the changes. Scientists have been studying nocturnal desert geckos to see how they are adapting to climatic changes. […]

  • Giant clams tell the story of past typhoons
    on May 24, 2018 at 2:40 pm

  • Birds play the waiting game in tough environmental conditions
    on May 23, 2018 at 1:12 pm

    If resources are limited and tough to find, reproductive efforts may fail. In these situations, it may be in an animal's best interests to not defend a territory or to breed at all, but rather focus its efforts on surviving to the next breeding season. A new study presents some of the best evidence on how changes in environmental conditions, specifically droughts, impact the social and reproductive behavior of birds. […]

  • Floridians could far far more frequent, intense Heatwaves
    on May 23, 2018 at 1:12 pm

    By the late 21st century, if atmospheric greenhouse gas concentrations reach worst-case projections, Floridians could experience summer heatwaves three times more frequently, and each heatwave could last six times longer and be much hotter than at present, according to new research. […]

  • Lightning in the eyewall of a hurricane beamed antimatter toward the ground
    on May 21, 2018 at 5:15 pm

    Hurricane Patricia, which battered the west coast of Mexico in 2015, was the most intense tropical cyclone ever recorded in the Western Hemisphere. Amid the extreme violence of the storm, scientists observed something new: a downward beam of positrons, the antimatter counterpart of electrons, creating a burst of powerful gamma-rays and X-rays. […]

  • Monitoring of tropical trees in face of climate change
    on May 17, 2018 at 2:23 pm

    Experts have challenged the principle that tropical ecosystems are aseasonal -- after discovering regular cycles in fruiting, flowering and leafing in such climates. […]

  • Breakthrough in understanding rare lightning-triggered gamma-rays
    on May 17, 2018 at 2:22 pm

    The Telescope Array detected 10 bursts of downward terrestrial gamma-ray flashes (TGFs) between 2014 and 2016, more events than have been observed in rest of the world combined. They are the first to detect downward TGFs at the beginning of cloud-to-ground lightning, and to show where they originated inside thunderstorms. The array is by far the only facility capable of documenting the full TGF 'footprint' on the ground. […]
