Protecting the ozone layer is delivering vast health benefits
An international agreement to protect the ozone layer is expected to prevent 443 million cases of skin cancer and 63 million cataract cases for people born in the United States through the end of this century, according to new research. The research team, by scientists at the National Center for Atmospheric Research (NCAR), ICF Consulting, […]
Record-breaking ocean heat fueled Hurricane Harvey
BOULDER, Colo. May 11, 2018 — In the weeks before Hurricane Harvey tore across the Gulf of Mexico and plowed into the Texas coast in August 2017, the Gulf’s waters were warmer than any time on record, according to a new analysis led by the National Center for Atmospheric Research (NCAR). These hotter-than-normal conditions supercharged […]
North American storm clusters could produce 80 percent more rain
BOULDER, Colo. November 20, 2017 – Major clusters of summertime thunderstorms in North America will grow larger, more intense, and more frequent later this century in a changing climate, unleashing far more rain and posing a greater threat of flooding across wide areas, new research concludes.
