New paper links Arctic sea ice extent to absorption of sunlight by clouds
The Hockeyschtick writes: A new paper published in the Journal of Geophysical Research Atmospheres finds Arctic sea ice concentrations at the low of each summer are related to absorption of…
Nature abhors a positive feedback
Negative Feedback Prevents Harmful Temperatures from Carbon Dioxide Guest essay by Bryce Johnson The purpose of the article is to contribute to refuting the false alarm that has been generated…
Noctilucent clouds on the increase, climate change will likely be blamed
Of course, it might just be a negative feedback at work. From NASA: Appearance of Night-Shining Clouds Has Increased First spotted in 1885, silvery blue clouds sometimes hover in the…
Water Vapor Feedback
Guest Post by Willis Eschenbach Well, another productive ramble through the CERES dataset, which never ceases to surprise me. This time my eye was caught by a press release about…
We don't know clouds
Too many variables like clouds to model future climate with precision Guest essay by Rolf Westgard A new United Nations report suggests an imminent danger from global warming. It states…
Radiative Forcing, Radiative Feedbacks and Radiative Imbalance – The 2013 WG1 IPCC Report Failed to Properly Report on this Issue
Guest essay by Roger A. Pielke Sr. Main Points 1. The difference in ocean heat content at two different time periods provides the global average radiative imbalance over that time…
The Cloud Radiative Effect, Take Two
Guest Post by Willis Eschenbach Well, in my last post I took a first cut at figuring the cloud radiative “feedback” from the CERES dataset. However, an alert commenter pointed…
The Cloud Radiative Effect (CRE)
Guest Post by Willis Eschenbach [UPDATE: An alert commenter, Ken Gregory, has pointed out that in addition to the temperature affecting the CRE, it is also affected by the changing…
Another negative climate feedback: more CO2 = more plants = more aerosols = cooling
Recall a couple of days ago that I posted on the aerosols released by trees: Those dirty trees: why hasn’t the EPA called for trees to be regulated? Now, from…
Forcing or Feedback?
Guest Post by Willis Eschenbach I read a Reviewer’s Comment on one of Richard Lindzen’s papers today, a paper about the tropics from 20°N to 20°S, and I came across…
Clive Best gives evidence for negative water feedback in Earth's climate system using the faint sun paradox and CRUTEM4 data
Excerpts from Evidence for Negative Water Feedback by Clive Best Abstract: Positive linear climate feedback for combined water effects is shown to be incompatible with the Faint Sun Paradox. In…
No new strange attractors: strong evidence against both positive feedback and catastrophe
This is a comment by Dr. Robert Brown on the What we don’t know about Earth’s energy flow post. I thought it was so insightful on the topic of climate stability…
Feedback about feedbacks and suchlike fooleries
By Christopher Monckton of Brenchley Responses to my post of December 28 about climate sensitivity have been particularly interesting. This further posting answers some of the feedback. My earlier posting…
Send in the clouds, there ought to be clouds (in models)
New tool clears the air on cloud simulations LIVERMORE, Calif. — Climate models have a hard time representing clouds accurately because they lack the spatial resolution necessary to accurately simulate…
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…
Cloud Radiation Forcing in the TAO Dataset
Guest Post by Willis Eschenbach This is the third in a series ( Part 1, Part 2 ) of occasional posts regarding my somewhat peripatetic analysis of the data from the TAO moored buoys…
Bill Illis: Clouds account for most of the variability in net radiation at the Top of the Atmosphere
While we are marveling at the recent revelation out of Serbia that shows a connection between cosmic rays, clouds and temperature, our own volunteer moderator, Roger (Tallbloke) noticed and collated…
BREAKING NEWS – CERN Experiment Confirms Cosmic Rays Influence Cloud Seeds
UPDATE: see some reactions to this announcement here From the GWPF This refers to the CLOUD experiment at CERN. I’ll have more on this as it develops (updated twice since…
It's Not About Feedback
Guest Post by Willis Eschenbach The current climate paradigm believed by most scientists in the field can be likened to the movement of balls on a pool table. Figure 1.…
Which way to the feedback?
Guest Post by Willis Eschenbach There is an interesting new study by Lauer et al. entitled “The Impact of Global Warming on Marine Boundary Layer Clouds over the Eastern Pacific—A…
Old climate models do a bad job with clouds, so a new model says "warming must be worse"
From the “it’s worse than we modeled department”, a case of “head in the clouds” thinking: From the University of Hawaii at Manoa via Eurekalert press release: Study could mean…
