    In a new study published in Nature on Monday, scientists say they have for the first time thoroughly documented one of the most profound planetary changes yet to be caused by a warming climate: The distribution of clouds all across the Earth has shifted, they say.
    And moreover, it has shifted in such a way — by expanding subtropical dry zones, located between around 20 and 30 degrees latitude in both hemispheres, and by raising cloud tops — as to make global warming worse.
    The study observed this change, but a northward shifting of storm tracks was not the only effect. The tops of clouds are also now reaching higher into the atmosphere.
    Here’s how the paper summarizes the changes, region by region: "cloud amount and albedo [i.e., reflectivity] increased over the northwest Indian Ocean, the northwest and southwest tropical Pacific Ocean, and north of the Equator in the Pacific and Atlantic oceans. Cloud amount and albedo decreased over mid-latitude oceans in both hemispheres (especially over the North Atlantic), over the southeast Indian Ocean, and in a northwest-to-southeast line stretching across the central tropical South Pacific."
