A very interesting post ………..tnx to WUWT!!!

Watts Up With That?

From the University of Colorado at Boulder

CU-Boulder researchers use climate model to better understand electricity in the air

Electrical currents born from thunderstorms are able to flow through the atmosphere and around the globe, causing a detectable electrification of the air even in places with no thunderstorm activity.

But until recently, scientists have not had a good understanding of how conductivity varies throughout the atmosphere and how that may affect the path of the electrical currents. Now, a research team led by the University of Colorado Boulder has developed a global electric circuit model by adding an additional layer to a climate model created by colleagues at the National Center for Atmospheric Research (NCAR) in Boulder.

Watts Up With That?

Guest essay by Marlo Lewis

Okay, they don’t do so in as many words. But in addition to being more confident than ever (despite a 16-year pause in warming and the growing mismatch between model projections and observations) that man-made climate change is real, they are also more confident nothing really bad is going to happen during the 21st Century.

The scariest parts of the “planetary emergency” narrative popularized by Al Gore and other pundits are Atlantic Ocean circulation shutdown (implausibly plunging Europe into a mini-ice age), ice sheet disintegration raising sea levels 20 feet, and runaway warming from melting frozen methane deposits.
