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:

“100s of Millions of People will Die”

By Eric Worrall – Re-Blogged From WUWT

h/t Bob in Castlemaine; The Head of the Australian Conservation Foundation Kelly O’Shanassy delivered a solemn warning last Tuesday to a packed audience of journalists, claiming that if we continue to burn coal and breach the 1.5C IPCC climate limit, “100s of millions of people will die”.

Scottish Sunspots

By Willis Eschenbach – Re-Blogged From WUWT

In a recent post, Anthony published Leif Svalgaard’s new paper showing 9,000 years of reconstructed solar activity.

In the discussion, someone pointed out that the “Maunder Minimum”, a time of very low solar activity, corresponds with the coldest decade in a long-term reconstruction of summer temperatures in Scotland. Their temperature reconstruction is based on a group of pine tree-ring records spanning 800 years. Their graph is shown below:

2018 U.S. tornadoes on Track to be Lowest Ever

By Anthony Watts – Re-Blogged From WUWT

While claims of increased severe weather due to “climate change” aka “global warming” are thrown about by the media, with recent claims that more and more tornadoes are shifting east in the U.S., the fact of the matter is that the trend for strong tornadoes is decidedly down, according to data from NOAA. The US is on track to have the lowest annual tornado count in 65 years.

Climate and the Hysterical And Confused Media

By Holman W. Jenkins, Jr. – Re-Blogged From WUWT

On Climate, Don’t Listen To The Hysterical And Confused Media

Journalists have been herniating themselves unnecessarily in covering a new report from the Intergovernmental Panel on Climate Change finding that global temperature might increase by another 0.9 degrees Fahrenheit sometime between 2030 and 2052.

The truth is, any reporter with a fifth-grade education could have made the same calculation last week, last year or 10 years ago by applying the standard climate-sensitivity estimate (in use since 1979) to the standard emissions forecasts.
