Tweaking the climate models: Researchers show emissions from forests influence very first stage of cloud formation

Clouds are the largest source of uncertainty in present climate models. Much of the uncertainty surrounding clouds’ effect on climate stems from the complexity of cloud formation. New research from scientists at the CLOUD experiment at CERN, including Carnegie Mellon’s Neil Donahue, sheds light on new particle formation — the very first step of cloud…

Electric-blue night clouds are invading the U.S.

Reposted from Dr. Roy Spencer’s Blog I have personally cussed out Dr. Spencer for adding an item to my bucket list which had been almost complete.~ctm June 11th, 2019 by Roy W. Spencer, Ph. D. Over the next few weeks, mid-latitude observers might experience the best noctilucent cloud viewing of their lifetimes. Extremely high-altitude noctilucent…

Study: UHI in Los Angeles is driving off coastal clouds that dampen California wildfires

From the THE EARTH INSTITUTE AT COLUMBIA UNIVERSITY and “an actual case of man-made climate change” department. Urbanization and climate change combine to heighten danger Sunny California may be getting too sunny. Increasing summer temperatures brought on by a combination of intensifying urbanization and warming climate are driving off once common low-lying morning clouds in many…

NASA satellite captures photo of bizarre circle of clouds

Sometimes, nature just gives us the weird. While clouds are an important topic of research for climatologists and meteorologists, sometimes the atmosphere churns up peculiar-looking cloud formations that are as notable for aesthetic reasons as they are for scientific ones. That was the case in May when this circular swirl of clouds drifted over Lake Balkhash in eastern Kazakhstan. In…
