Drying The Sky

By Willis Eschenbach – Re-Blogged From WUWT

Eleven years ago I published a post here on Watts Up With That entitled “The Thermostat Hypothesis“. About a year after the post, the journal Energy and Environment published my rewrite of the post entitled “THE THUNDERSTORM THERMOSTAT HYPOTHESIS: HOW CLOUDS AND THUNDERSTORMS CONTROL THE EARTH’S TEMPERATURE“.

When I started studying the climate, what I found surprising was not the warming. For me, the oddity was how stable the temperature of the earth has been. The system is ruled by nothing more substantial than wind, wave, and cloud. All of these are changing on both long and short time cycles all of the time. In addition, the surface temperature is running some thirty degrees C or more warmer than would be expected given the strength of the sun.

Weekly Climate and Energy News Roundup #374

The Week That Was: August 31, 2019, Brought to You by www.SEPP.org

Quote of the Week: What I cannot create, I do not understand. – Richard Feynman

Number of the Week: 6,000 times more accuracy needed!


Nothing New in AGW: David Whitehead briefly reviews several new studies which demonstrate where and how Global Climate Models are failing. The first one listed, in Science Mag, discusses how humans have been changing the face of the Earth for up to 10,000 years. There is a large project underway, ArchaeoGLOBE, which is gathering data and various areas of the globe, to include change of land use from agriculture be it animal husbandry or farming. Archaeologists have discovered that humans have modified corn for some 10,000 years.

The ArchaeoGLOBE Project was based on a questionnaire to more than 200 archaeologists with 10 distinct time points from 10,000 years ago to 1850. Data were collected for four land use categories: foraging, hunting, gathering and fishing. Such work might provide valuable information on how humans affected different regions of the globe, and what tools were used. Also, the study dispels the common notion than human impact on climate did not start until about 1850, so human impact on nature and climate is nothing new.

Quote of the Week: “…we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have…. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.” – Stephen Schneider, Discover, pp. 45–48, October 1989.

Number of the Week: 0.05ºC in 25 years

Honest Science: The full comment by Stephen Schneider in the 1989 interview in Discover magazine, cited above, is:

“On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but — which means that we must include all the doubts, the caveats, the ifs, ands, and buts. On the other hand, we are not just scientists but human beings as well. And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climatic change. To do that we need to get some broad-based support, to capture the public’s imagination. That, of course, entails getting loads of media coverage. So, we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This ‘double ethical bind’ we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest. I hope that means being both.”

Declining Solar Activity

By Bob Hoye – Re-Blogged From WUWT

In the 1990s, solar physicists, Penn and Livingston, called for a long decline in solar activity. This is the case and it is nice to see such work confirmed by events. Solar Cycles # 23 and 24 are the weakest since the early 1900s. The current run of consecutive Spotless Days is out to 33, or 75%, for the year.

The following table shows the record back to the minimum of Solar Cycle # 23 when the count was at 268 days, or 73%, for 2008.

Data: Global Temperatures Rose As Cloud Cover Fell In the 1980s and 90s

By Paul Homewood – Re-Blogged From WUWT

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 atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.”

We continue that conversation with this entry from Paul Homewood.


We’ve been discussing the sudden rise in UK and European temperatures in the 1990s, and I was reminded about a study undertaken by Clive Best and Euan Mearns looking at the role of cloud cover four years ago:

Of Water And Albedo

By Willis Eschenbach – Re-Blogged From WUWT

As usual, there is more to learn in the CERES satellite dataset. I got to thinking of the idea put forth by Lacis 2010. He announced model results claiming that if the only modeled greenhouse gas in the modeled atmosphere were modeled water, the model world would basically evolve to a modeled ice over condition at a modeled -20°C (-4°F). Here is his money graph, showing the evolution of various modeled climate measurements in the first fifty modeled years after removing all modeled GHGs except for modeled water from the modeled atmosphere. See his paper for details.
