The modelers of the 1990’s where on the right track – if clouds change the results would be as strong as the that expected from CO2. The IPCC should evaluate…

An Interview with Top Climate Scientist Bjorn Stevens
We should keep looking, but so far there’s no evidence that clouds play a major role.
Global Scatterplots
Guest Post by Willis Eschenbach For a while now, I’ve been using a curious kind of scatterplot. Here’s an example. It shows the relationship between the surface temperature and the…
Updated Climate Models Clouded by Scientific Biases, Researchers Find
After all, the ultimate goal of any model evaluation study is to help improve those models.”
Thoughts About Clouds And Water (Vapor)
Climate models are NOT capable of modeling clouds. Their resolution is too low and clouds are too complex.
Ocean Atmosphere Response to Solar EMR at Top of the Atmosphere
How can climate models hope to reflect the real world when clouds are parameterised with no sensitivity to surface temperature?
The Big 5 Natural Causes of Global Warming part 5: How Clouds Moderate Global Warming
Any global reduction of cloud cover increases global warming. And reduction of local clouds can cause heat waves.
Clouds Haven’t Behaved the Way the IPCC Or the Models Say
My paper argues that clouds behaved largely independently of CO2 and had as much of a warming effect as CO2, maybe much more.
Where have all the Clouds gone and why care?
By Charles Blaisdell PhD ChE The earth’s cloud cover has long been an important puzzle in climate change. Cloud cover has many types and varies significantly from year to year. …
Radiative energy flux variations from 2000 – 2020
The time span of 20 years is still too short to be able to decide conclusively whether the current heating phase is a temporary or permanent development. In the former…
A Robust Balance
Guest Post by Willis Eschenbach Albedo is the percentage of incident light that is reflected by an object. For years, I’ve read claims that the loss of Arctic sea ice…
How do higher waves cause more ice clouds? Researchers claim expedition into arctic sea explains
Scientists explain the peculiar interplay that exists between sea-ice decline, wave height, and ice cloud formation over the Arctic
Uncertain Clouds
Guest Post by Willis Eschenbach I read an interesting quote in the latest Climanifesto from the Intergovernmental Panel on Climate Change, their Sixth Assessment Report, known as “IPCC AR6” to…
Clouds and Global Warming
By Andy May This post is inspired by an old post on the CERES cloud data by Willis Eschenbach that I’ve read and re-read a lot, “Estimating Cloud Feedback Using…
A pertinent climate question
How much of a change in cloudiness would it take to account for the 0.53 W/m2 increase in TOA radiative forcing since 2003?
Aerosol formation in clouds
“Our experimental setup allows us for the first time to precisely investigate the distribution of organic vapours at the air-water interface under near-environmental conditions,” says Houssni Lamkaddam, a researcher in…
Study: Global Warming Heating Nights Faster than Days
And both increased and decreased cloud cover is bad.
Increased warming in latest generation of climate models likely caused by clouds
As scientists work to determine why some of the latest climate models suggest the future could be warmer than previously thought, a new study indicates the reason is likely related…
Noctilucent Clouds Over London
On June 21st, something rare and magical happened in London. The skies of the great city filled with noctilucent clouds (NLCs). Phil Halper noticed the display, grabbed a camera, and…
Record Cold Upper Mesospheric Temperatures Suggest Another Good Noctilucent Cloud Viewing Season
From Dr Roy Spencer’s Blog May 31st, 2020 by Roy W. Spencer, Ph. D. Noctilucent clouds (NLCs) are often visible in the extreme upper atmosphere (80-85 km altitude) well after…
