Extreme Weather in a Changing Climate: NCAR Asking the Right Questions

When a deadly heat wave lingers for an especially long time; when a hurricane makes landfall with particular ferocity; or when droughts, winter storms or cold snaps break records, the public is increasingly interested in knowing if human-induced climate change played a role. Attributing individual extreme weather events to a warming climate is difficult work. Even so, scientists have been making an effort in recent years to determine when a connection can be detected. In a new "Perspective" piece published in Nature Climate Change, scientists at the National Center for Atmospheric Researc...

Google, NASA Work Together on Disney Show to Inspire Girls Into Sciences

The Washington Post

When it was developing a new series about a family of space adventurers, Disney Junior wanted the show to help bury common media stereotypes about science and programmers, so it turned to the U.S. National Aeronautics and Space Administration (NASA) and Google for advice. A 2014 report by Google found a paucity of media portrayals of women in science has contributed to the low rate of girls pursuing science, technology, engineering, and math careers. Disney Junior visited Google headquarters in Silicon Valley and NASA's Southern California base to speak ...

PERSPECTIVE - It’s Time for Every Student to Learn to Code

Learning to code is about more than career readiness. It’s about helping students make sense of their digital world

Recently, there has been a lot of discussion around the importance of coding in the K-12 classroom. Should it be compulsory for all students? An elective? Reserved for those students considering a computer science major in college? The answer may come down to supply and demand. According to the Bureau of Labor Statistics, by 2020, there will be 1.4 million computing jobs and only 400,000 computer science students to fill those roles. This represents a gap...
