TEXT 1: How brightly the moon glows is a mystery, but maybe not for long.


    “The lunar dark side may be the moon’s more mysterious face, but there’s something pretty basic scientists still don’t know about the bright side — namely, just how bright it is.

    Current estimates of the moon’s brightness at any given time and vantage point are saddled with at least 5 percent uncertainty. That’s because those estimates are based on measurements from ground-based telescopes that gaze at the moon through the haze of Earth’s atmosphere.

    Now, scientists have sent a telescope beyond the clouds on a high-altitude airplane in hopes of gauging the moon’s glow within about 1 percent or less uncertainty, the National Institute of Standards and Technology reports in a Nov. 19 news release.

    Knowing the exact brightness of Earth’s celestial night-light could increase the reliability of data from Earth-observing satellites that use the moon’s steady glow to check that their sensors are working properly. Those satellites keep tabs on things like weather, crop health and dangerous algal blooms.”

Climate change: Oceans running out of oxygen as temperatures rise


    “Climate change and nutrient pollution are driving the oxygen from our oceans, and threatening many species of fish.
     While nutrient run-off has been known for decades, researchers say that climate change is making the lack of oxygen worse. Around 700 ocean sites are now suffering from low oxygen, compared with 45 in the 1960s.
    Researchers say the depletion is threatening species including tuna, marlin and sharks.
     The scientists estimate that between 1960 and 2010, the amount of the gas dissolved in the oceans declined by 2%. That may not seem like much as it is a global average, but in some tropical locations the loss can range up to 40%.
    If countries continue with a business-as-usual approach to emissions, the world's oceans are expected to lose 3-4% of their oxygen by the year 2100.
    This is likely to be worse in the tropical regions of the world. Much of the loss is expected in the top 1,000m of the water column, which is richest in biodiversity.
    "Ocean oxygen depletion is menacing marine ecosystems already under stress from ocean warming and acidification," said Dan Laffoley, also from IUCN and the report's co-editor. "To stop the worrying expansion of oxygen-poor areas, we need to decisively curb greenhouse gas emissions as well as nutrient pollution from agriculture and other sources."”
