NASA: Melting Ice Sheets Is Changing How the Earth Rotates

The data of disasters

When disaster strikes, those affected often turn to social media to request aid, offer assistance, or share other information in real time. In recent years, data scientists have begun analyzing millions of Facebook posts and tweets in order to study the collective response before, during and after a crisis.  In the face of this mountain of information, however, it can be hard to identify the most relevant posts and trends. But thanks to a close collaboration between social science and software engineering, University of Colorado Boulder researchers Leysia Palen and Kenneth Anderson are innovating new ways to find the underlying human behaviors hidden within noisy data…

 

NASA: Melting Ice Sheets Is Changing How the Earth Rotates

Driven by dwindling polar ice, climate change is actually changing the way the Earth spins, new research shows. Melting ice sheets are contributing to the change in polar motion, a term scientists use to describe the “periodic wobble and drift of the poles.” A researcher at NASA’s Jet Propulsion Laboratory said there has been a “dramatic shift” since 2000 and while not seen as dangerous, this shift is “due to climate change, without a doubt.” Greenland and Antarctica combined are losing more than 400 billion tons of ice per year and smaller glaciers around the world are also losing mass, contributing to the shift…
