The Warmer The Icier

Watts Up With That?

Guest Post by Willis Eschenbach

A WUWT commenter emailed me with a curious claim. I have described various emergent phenomena that regulate the surface temperature. These operate on time scales ranging from minutes to hours (e.g. dust devils, thunderstorms) to multi-decadal (e.g. Atlantic Multidecadal Oscillation, Pacific Decadal Oscillation). He suggested that there is also a much slower thermostatic mechanism at play over thousands of years and longer.  Here’s how I understand it.

He said that when it gets warmer, the atmosphere is more moist, so there is more snow on Antarctica. This translates into more ice on the ice cap, which puts increased pressure on the ice below. Now, the ice gain at the surface and the ice loss in the calving of the Antarctic glaciers is in some kind of long-term very slow-moving steady state. Pressure at the top squeezes out the ice on all sides. So increasing the…

Analysis of the Relationship Between Land Air Temperatures and Atmospheric Carbon Dioxide Concentrations

Watts Up With That?

Guest essay by Clyde H. Spencer

Before getting into the details of the analysis, it must be stated that there are a number of issues with the available temperature data sets. Some critics have dismissed the historical ocean pH measurements because of the poor spatial sampling. However, the same criticism can be made about historical temperatures. There are still concerns about the influence of the Urban Heat Island effect on recent temperature readings. In addition, the temperature record is a moving target because there are on-going changes made to try to correct for the shortcomings of a system that wasn’t intended to be used to track long-term changes. Therefore, if you attempt to reproduce my results, you will probably find that the data have changed. The Berkeley Earth Surface Temperature (BEST) project was started because of distrust in the other existing data sets. I have chosen to use BEST data…

The Penguin Strikes Back

Watts Up With That?

Guest Post by Willis Eschenbach

Well, once again we’ve proven that Mark Twain was right when he observed that “A lie can travel half way around the world while the truth is putting on its shoes.” … but the response time of the truth is getting better. Three days ago guest author Eric Worrall, in a post called Chris Turney: Penguins Don’t Migrate, they’re dying!,  highlighted the claims of the oft-wrong-but-never-uncertain Chris Turney, the leader of the Ship of Fools antarctic expedition. Turney claimed that 140,000 penguins had been killed by climate change. However, since then the penguin forces of science have mustered to defeat his defeatism.

Disappearing the MWP at Icefields, Alberta

Climate Audit

In today’s post, I’m going to critically examine another widely used tree ring chronology: the Icefields (Alberta) MXD RCS chronology of Luckman and Wilson (2005 pdf), used most recently in Wilson et al 2016.

I’ll show that the RCS technique used in the LW2005 MXD chronology eliminated high medieval values as a tautology of their method, not as a property of the data and that the Icefields data provides equal (or greater) justification for MXD RCS chronologies with elevated medieval values.  The measure of potential difference is previewed in Figure 1 below, which compares the reported LW2005 chronology (top panel) to an MXD chronology with elevated medieval values, calculated using equally (or more plausible) RCS methodology, with several other similar variations shown in the post.

FDR’s Economic Policies FAILED. But Don’t Take My Word For It, Listen To Obama’s TOP Economic Adviser

Start Thinking Right

Everyone ought to be familiar with the words of Franklin Delano Roosevelt’s Treasury Secretary:

“We have tried spending money. We are spending more than we have ever spent before and it does not work. And I have just one interest, and if I am wrong … somebody else can have my job. I want to see this country prosperous. I want to see people get a job. I want to see people get enough to eat. We have never made good on our promises… I say after eight years of this Administration we have just as much unemployment as when we started… And an enormous debt to boot!” – Henry Morganthau, FDR’s Treasury Secretary, May 1939

And for the record, in April 1939, the unemployment rate was 20.7%.  Anybody who thinks that FDR’s policies did anything but dig us deeper into depression are morons.

But few Americans have ever…

How the progressive left intends to use the courts to harass those who don’t agree with them on the climate

Watts Up With That?

Combatting Climate Change in the Courts
by David W. Schnare
General Counsel Energy & Environment Legal Institute


On February 10th, the American Constitution Society for Law and Policy (“ACS”) hosted a panel discussion on legal approaches and activities associated with “combatting” climate change through legal action. Topics covered were RICO prosecutions, climate torts and the Supreme Court’s stay of the Clean Power Plan. The session was organized and moderated by Lisa Heinzerling, the attorney who was brought into EPA to manage the legal analysis of how to extend the agency’s powers beyond the limits of the Clean Air Act in order to implement the environmental activists’ climate agenda, and who had previously won the Massachusetts v. EPA case enabling EPA to regulate carbon dioxide. The discussion panel consisted of Richard E. Ayres, Founding Partner, Ayres Law Group, LLP; Co-Founder, Natural Resources Defense Council; Sharon Eubanks, Partner, Bordas & Bordas, PLLC…

Shock Study: Some School Students are Still Taught about Climatic Natural Variation

Watts Up With That?

Galileo before the Holy Office, a 19th-century painting by Joseph-Nicolas Robert-Fleury Galileo before the Holy Office, a 19th-century painting by Joseph-Nicolas Robert-Fleury

Guest essay by Eric Worrall

A study published in Science reveals that a number of teachers are rebelling against Federal education directives – that a significant number of school teachers are failing to indoctrinate their students with the politically approved position on climate change, or worse, are teaching students that there are forcings other than CO2, which might be driving changes in global temperature.

According to the Washington Post;

A major new survey of U.S. middle school and high school science teachers has found that across the country, a majority are teaching about climate change in their classrooms — but a significant percentage are also including incorrect ideas, such as the notion that today’s warming of the globe is a “natural” process.

The study, published in Science Thursday by Eric Plutzer of Penn State University and a number…
