Experts reveal that clouds have moderated warming triggered by climate change
A new study has revealed how clouds are modifying the warming created by human-caused climate change in some parts of the world Swansea University A new study has revealed how…
No, Increasing CO2 isn’t going to trigger a hot world without clouds.
From Dr. Roy Spencer’s blog, March 1st, 2019 by Roy W. Spencer, Ph. D. I’ve received many more requests about the new disappearing-clouds study than the “gold standard proof of…
A new view: Observing Clouds in Four Dimensions
Six cameras are revolutionizing observations of shallow cumulus clouds. The Science While easily seen by people, the cotton-ball clouds (called shallow cumulus clouds) that drift overhead on partly cloudy days…
Data: Global Temperatures Rose As Cloud Cover Fell In the 1980s and 90s
Climatologist Dr. Roy Spencer has pointed out in his book, “The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the…
An interview with Henrik Svensmark: cosmic rays, clouds and climate
Prof Henrik Svensmark & Jacob Svensmark discuss the connection between cosmic rays, clouds and climate with the GWPF’s Benny Peiser and Jonny Bairstow from Energy Live News after his recent…
CERES Edition 4 and the Cloud Radiative Effect
Guest Post by Willis Eschenbach One of the enduring questions in climate involves what is usually called “cloud feedback”. When the earth warms up a bit, the clouds change in…
Study: Climate models underestimate cooling effect of daily cloud cycle
From PRINCETON UNIVERSITY: Princeton University researchers have found that the climate models scientists use to project future conditions on our planet underestimate the cooling effect that clouds have on a daily…
NASA detects strange electric-blue clouds over Antarctica
NASA’s AIM spacecraft is monitoring a vast ring of electric-blue clouds circling high above Antarctica. These are noctilucent clouds (NLCs), made of ice crystals frosting specks of “meteor smoke” in the…

A Cloudy Question: was 'the pause' caused by a change in global cloud cover?
Guest essay by Mike Jonas I have been looking at some cloud data (from ISCCP: isccp.giss.nasa.gov all available monthly “EQ” data (equal-area grid)) and an interesting question arises. I haven’t…
Thin tropical clouds cool the climate
From STOCKHOLM UNIVERSITY: Thin clouds at about 5 km altitude are more ubiquitous in the tropics than previously thought and they have a substantial cooling effect on climate. This is shown…
