    Climate change works in mysterious ways; it isn’t limited to wildfires and melting ice. Today’s climate exhibit: The 100th Meridian — the famous dividing line that separates America’s wet East from the dry West — has migrated 140 miles east since 1980. https://grist.org/article/this-gif-shows-how-far-the-100th-meridian-has-shifted-since-1980/ The shift is the result of rising temperatures drying out parts of the northern plains and less rain falling further south, YaleEnvironment360 reports. This could be due to natural variability — changes caused by nonhuman forces — but the migration aligns with what researchers tell us to expect from global warming. https://e360.yale.edu/features/redrawing-the-map-how-the-worlds-climate-zones-are-shifting

    “When you’re lost in the rain in Juarez when it’s Easter time, too
    And your gravity fails and negativity don’t pull you through
    Don’t put on any airs when you’re down on Rue Morgue Avenue
    They got some hungry women there and they really make a mess outta you”

    (2/22/19): “An international research team including astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has combined radio telescopes from five continents to prove the existence of a narrow stream of material, a so-called jet, emerging from the only gravitational wave event involving two neutron stars ever observed. With its high sensitivity and excellent performance, the 100-meter radio telescope in Effelsberg played an important role in the observations. https://phys.org/news/2019-02-jetcocoon-riddle-gravitational-event.html
    In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors. Neutron stars are ultra-dense stars, roughly the same mass as the Sun, but similar in size to a city like Cologne. This event is the first and only one of this type that has been observed so far, and it happened in a galaxy 130 million light-years away from Earth, in the constellation of Hydra.
    Astronomers observed the event and the subsequent evolution across the entire electromagnetic spectrum, from gamma-rays, X-rays to visible light and radio waves. Two hundred days after the merger, observations combining radio telescopes in Europe, Africa, Asia, Oceania, and North America proved the existence of a jet emerging from this violent collision. These findings are now published in the scientific journal Science by an international team of astronomers, led by Giancarlo Ghirlanda from the Italian National Institute for Astrophysics (INAF).” See also “Compact radio emission indicates a structured jet was produced by a binary neutron star merger” http://science.sciencemag.org/content/early/2019/02/20/science.aau8815?rss=1
