Dr. Willie Soon versus the Climate Apocalypse

Dr. Jeffrey Foss – Re-Blogged From WUWT

More honesty and less hubris, more evidence and less dogmatism, would do a world of good

“What can I do to correct these crazy, super wrong errors?” Willie Soon asked plaintively in a recent e-chat. “What errors, Willie?” I asked.

“Errors in Total Solar Irradiance,” he replied. “The Intergovernmental Panel on Climate Change keeps using the wrong numbers! It’s making me feel sick to keep seeing this error. I keep telling them – but they keep ignoring their mistake.”

U.S. Climate Science Special Report

By Bob Tisdale – Re-Blogged From WUWT

Chapter 6 – Temperature Changes in the United States of the U.S. Global Change Research Program’s recently published Climate Science Special Report (2017) clearly shows and discusses, under the heading of “6.1.2 Temperature Extremes”, how temperature extremes for the contiguous United States have become more moderate over the last 118 years, with the coldest daily temperatures warming and the warmest daily temperatures cooling. In other words, temperature-extreme-related climate in the United States has improved.

The Froth of the Fourth

by Willis Eschenbach – Re-Blogged From WUWT

I see that the Fourth US National Climate Assessment has just been published. It’s here, and it should be required reading for those masochists who like overblown claims, flimsy justifications, and ridiculous pretensions.

The fun thing about each of the Climate Assessments is that after an initial flurry of media hype following the publication of their latest hyperbolic claims, everyone ignores them. They sink with the sad finality of an outboard motor spark plug accidentally dropped overboard two miles at sea …

The Picasso Problem

By Willis Eschenbach [See update at end.] – Re-Blogged From WUWT

Let me start explaining the link from Picasso to climate science by looking at what Dr. Nir Shaviv called “the most boring graph I have ever plotted in my life”.

This is the graph of the changes in the best estimate of the range of what is called “climate sensitivity” over the last forty years or so.

What is climate sensitivity when it’s at home? To explain that, I’ll have to take a slight detour. First, downwelling radiation.

A Quick Post before the Monthly Global Surface and TLT Temperature Update

By Bob Tisdale – Re-Blogged From WUWT

I’m adding Two Graphs to my Monthly Global Surface and TLT Temperature Updates. The new graphs are being added for a simple reason: to provide different perspectives on the increases in global temperatures since 1979.

The graphs are of Berkeley Earth global land+ocean surface temperature data and RSS global lower troposphere temperature data, both in absolute (not anomaly) form. That way they include the annual cycles in temperatures, which are far greater than the warming that’s occurred since 1979, based on their linear trends.

California, Temperatures, and Acres Burned

By Willis Eschenbach – Re-Blogged From WUWT

Inspired by the work done by Robert Rohde attempting to link May to October temperatures and rainfall to fires, I thought I’d take a look at the acres burned over the years. Rohde compared the rainfall and temperature records and highlighted the largest fires. However, this gives only a few data points. I wanted a larger view of the situation.

So instead of major fires, I looked at the areas burned every year, which are available here. There is complete data from 1959 to 2016, and the last two years are available here and here.

The first thing I did was run a multiple regression on the data, using both May to October temperature and May to October rainfall to see how well they would predict the area burned. To my great surprise, I found out that rainfall is not significantly correlated with the area burned. Here is that result:

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:
