High level clouds and surface temperature
Guest post by Erl Happ The orbit of the Earth’s around the sun is slightly eccentric. The closest point is called the perihelion. On January 4th the Earth is just…
Cloud cools
Guest post by Erl Happ This post was generated in response to the Christopher Monkton thread. It is not a criticism of Christopher Monkton but of our tendency to imagine…
New peer reviewed paper: clouds have large negative cooling effect on Earth's radiation budget
Oh dear, now we have three peer reviewed papers (Lindzen and Choi, Spencer and Braswell, and now Richard P. Allan) based on observations that show a net negative feedback for…
Prey and predator model of clouds
From the Weizmann Institute of Science – Eat, Prey, Rain Photo: Tamar Deutsch What do a herd of gazelles and a fluffy mass of clouds have in common? A mathematical…
While the Sun's in a funk, no hint of resumed ocean warming
Global SST Update: Still No Sign of Resumed Warming by Roy W. Spencer, Ph. D. Here’s the global average sea surface temperature (SST) update from AMSR-E on NASA’s Aqua satellite,…
World War II bombing raids offer new insight into the effects of aviation on weather
From Wiley-Blackwell via Eurekalert Wartime weather records reveal impact of contrails caused by USAAF raids Climate researchers have turned to the Allied bombing raids of the Second World War for…
Contrails – itty bitty icy forcing
From the American Geophysical Union weekly highlights: Estimating climate effects of contrails Condensation trails, or so-called contrails, formed by freezing of ice crystals in the exhaust from aircraft jet engines…
Uncertain Climate Risks (Nature Climate Change)
Guest Post by Ira Glickstein As I continue to plow through Vol 1 Issue 1 of the new Journal Nature Climate Change, I came to the following amazing statement: Communicating…
Clouds, radiative forcing, and climate models – still tweaking
As most readers know, clouds are still poorly understood and under-represented in climate models. This new research may help. From: DOE/Pacific Northwest National Laboratory Effect of cloud-scattered sunlight on earth’s…
Global Warming is a Pussy Cat
Guest post by Ira Glickstein Thanks to WUWT readers who posted estimates of how much of the supposed 0.8ºC Global Warming since 1880 was due to Data Bias, Natural Cycles,…
Cloud Cellular Communication
No, I’m not talking about the Internet or the latest mobile phone. Apparently clouds are “teleconnected”. Two press releases were made the yesterday on the same subject, both are presented…
Noctilucent clouds may be more visible during this summer
From SpaceWeather.com Every summer since the late 19th century, Earth’s polar skies have lit up with gossamer, electric-blue clouds, twisting and rippling in the twilight sky. They’re called noctilucent (“night-shining”)…
Spencer: Clouds Dominate CO2 as a Climate Driver Since 2000
By Dr. Roy Spencer, PhD. Last year I posted an analysis of satellite observations of the 2007-08 global cooling event, showing evidence that it was due to a natural increase…
Spencer on his AGU presentation yesterday
Little Feedback on Climate Feedbacks in the City by the Bay by Roy W. Spencer, Ph. D. The Fall meeting of the American Geophysical Union (AGU) here in San Francisco…
What climate news you aren't seeing in the American press but can in Iran
It’s really rather sad that you can read about Svensmark’s climate research in an Iranian news outlet (FARS) but you won’t see any mention of it in American press, such…
