The cloud patterns that surround planet Earth appear to be changing their formation,according to PrairiePublic.org. A new study attributes the shift to global warming. The study used satellite data dating back to the 1980s to track cloud patterns.
Subtropical dry zones are expanding, and the highest clouds are rising even higher. As the equatorial areas grow warmer, clouds are retreating to the poles. But there is disagreement among scientists about what this movement means.
Kevin Trenberth at the National Center for Atmospheric Research in Colorado, says climate researchers still have a lot of work to do when it comes to understanding clouds.
The findings appeared in last week’s issue of the journal Nature.
