NASA-funded network tracks the recent rise and fall of ozone depleting pollutants

A short-lived resurgence in the emission of ozone depleting pollutants in eastern China will not significantly delay the recovery of Earth s protective sunscreen layer, according to new research published Feb. 10 in Nature.

By Lara Streiff s NASA s Goddard Space Flight Center A short-lived resurgence in the emission of ozone-depleting pollutants in eastern China will not significantly delay the recovery of Earth’s protective “sunscreen” layer, according to new research published Feb. 10 in Nature. Stratospheric ozone, also known as Earth’s ozone layer, helps shield us from the Sun’s harmful Ultraviolet (UV) rays. Compounds like CFC-11 (Trichlorofluoromethane, also known as Freon-11), a chemical once considered safe and widely used as a refrigerant and in the production of insulation for buildings, rise to the stratosphere after emission on Earth’s surface. Once in the atmosphere, CFCs are broken down by the UV light and result in the destruction of ozone molecules,

Growth of northern Tibet proved the key to East Asian biodiversity

Credit: ZUO Linren Pioneering work led by a joint China-UK consortium has revealed the origin of one of the world s most important ecosystems, the East Asian biodiversity hotspot, thus solving a longstanding riddle as to what prompted its formation and evolution. In a recent study published in Science Advances, a joint research team led by scientists from Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences, the University of Bristol (UK) and the Open University (UK) has revealed the first direct mechanism explaining how the growth of mountains in Northern Tibet drastically altered climate, vegetation and plant diversity in East Asia.
