[…]

  • Polar vortex defies climate change in the Southeast U.S.
    on February 13, 2018 at 11:35 pm

    Overwhelming scientific evidence has demonstrated that our planet is getting warmer due to climate change, yet parts of the eastern US are actually getting cooler. According to a new study, the location of this anomaly, known as the 'US warming hole,' is a moving target. During the winter and spring, the US warming hole sits over the Southeast, as the polar vortex allows arctic air to plunge into the region, resulting in persistently cooler temperatures. […]

  • Bats as barometer of climate change
    on February 13, 2018 at 12:09 am

    Bats spend every night hard at work for local farmers, consuming over half of their own weight in insects, many of which are harmful agricultural pests, such as the noctuid moths, corn earworm and fall armyworm. And now they are arriving earlier in the season, and some of them are reluctant to leave. It seems the bats know more about climate change than we had realized. […]

  • Towards a better prediction of solar eruptions
    on February 7, 2018 at 7:03 pm

    Just one phenomenon may underlie all solar eruptions. Researchers have identified the presence of a confining 'cage' in which a magnetic rope forms, causing solar eruptions. It is the resistance of this cage to the attack of the rope that determines the power and type of the upcoming flare. This work has enabled the scientists to develop a model capable of predicting the maximum energy that can be released during a solar flare. […]
