The Obama administration is more certain than ever that global warming is changing Americans' daily lives and will worsen - conclusions that scientists will detail in a massive federal report to be released Tuesday.
Study co-author Donald Wuebbles (WUH'-buhls) of the University of Illinois said the National Climate Assessment will emphasize how the United States is already paying the multibillion-dollar price for man-made climate change. The report connects extreme weather events such as heat waves, storms and droughts to global warming.
He said final report is a rewritten and shortened version of a draft that was released in January 2013, with more scientific references, reviews by experts and the public, and a thorough review by the National Academy of Sciences.
