UAH Global Temperature Update for December 2018: +0.25 deg. C

By Dr. Roy Spencer’s – Re-Blogged From WUWT

January 2nd, 2019 by Roy W. Spencer, Ph. D.

2018 was 6th Warmest Year Globally of Last 40 Years

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for December, 2018 was +0.25 deg. C, down a little from +0.28 deg. C in November:

Global area-averaged lower tropospheric temperature anomalies (departures from 30-year calendar monthly means, 1981-2010). The 13-month centered average is meant to give an indication of the lower frequency variations in the data; the choice of 13 months is somewhat arbitrary… an odd number of months allows centered plotting on months with no time lag between the two plotted time series. The inclusion of two of the same calendar months on the ends of the 13 month averaging period causes no issues with interpretation because the seasonal temperature cycle has been removed, and so has the distinction between calendar months.

UAH Arctic Temperature Profile

By Kip Hansen – Re-Blogged From WUWT

Arctic_alone_featuredLast week Dr. Roy Spencer treated us to the latest UAH Global Temperature Update.  Overall, the ”global average lower tropospheric temperature (LT) anomaly for October, 2018 was +0.22 deg. C, up a little from +0.14 deg. C in September”.

Dr. Spencer was kind enough to include in his post, as he usually does, a chart with the actual figures from his ongoing research.  The entire post was mirrored here at WUWT.

Here’s the part that I found interesting, which only can be seen if one graphs the data from this chart:

Various regional LT departures from the 30-year (1981-2010) average for the last 22 months are:

If We Had Listened to Climate Scientists Back in 1979

By Alberto Z. Comendador – Re-Blogged From http://www.WattsUpWithThat.com

In two previous articles I made a point that seems inarguable but that advocates of emission cuts seldom acknowledge: the only worthy metric of progress in reducing emissions is the CO2 intensity of GDP, which one could also call CO2 efficiency. Looking at absolute emissions is absurd because absolute emissions depend largely or mostly on GDP and the growth thereof, which are of course unknown (especially if we’re making projections about the year 2100!).

In any case, climate policies aren’t supposed to reduce emissions by reducing GDP; sometimes advocates of emission cuts even brag about the economic benefits of their policies. So they can only work by reducing CO2 intensity, which is to say by increasing CO2 efficiency.

A second point hardly ever acknowledged is that CO2 efficiency isn’t static: it’s growing most of the time, in most places. It would have grown without the COP meetings and it did grow before the Kyoto agreement was signed – at a faster pace than thereafter.

End the IPCC

Climate models are lousy!

That wouldn’t be a big deal on its own, but that’s not the end of it. Those in power in the US – mostly of one party, but also many in the other – justify much of their stupid policies using the supposed accuracy of the models. A large part of those stupid policies center on the EPA’s War on Energy which, as it destroys the ability of private companies to provide cheap, dependable energy.

That energy is vital for many uses including heating, transport, cooking, and industry. The end game of the War on Energy is the impoverishment of American society. And, since our ability to defend ourselves against the many countries and cultures which want us dead depends on our Economy paying for that defense capability, those stupid policies, based on lousy models, threaten the very existence of our country.

Climate and Human Civilization Over the Last 18,000 Years

By Andy May – Re-Blogged From http://www.WattsUpWithThat.com

This is an updated timeline of climatic events and human history for the last 18,000 years. The original timeline was posted in 2013. The updated full size (Ansi E size or 34×44 inches) Adobe Reader version 8 PDF can be downloaded here or by clicking on Figure 1. It prints pretty well on 11×17 inch paper and very well on 17×22 inch paper or larger. To see the timeline in full resolution or to print it, you must download it. It is not copyrighted, but please acknowledge the author if you use it.

References to the images and data are given in this essay as hyperlinks. I’ve done my best to verify the accuracy of the content by checking multiple sources. When references had different dates for the same event, I chose the most commonly cited date or the most prestigious source. All dates (except some in the modern era) are given as “BP” or before the year 2000 for simplicity, using 1950 (the radiocarbon zero) was too cumbersome.

Science vs. Assumpsence: The Act of Knowing What You’re Quarreling About

By Geir Hasnes – Re-Blogged From http://www.WattsUpWithThat.com

Very often, and arguably most often, a disagreement is rooted in a lack of definition of what one agrees upon before starting the argument. Thus the argument soon develops into a quarrel, and while each side thinks he has won the argument in the end, he is also puzzled by why the other side doesn’t give in to the facts, of for instance, as in the case of the climate quarrel, the ‘Science’.

The statistician William M. Briggs, in his recent article Climate Change Alarmists Appear Immunized against Reality (link) asks: “This brings us to the crucial question: how do we reach educators like Johnson? We can’t do it with reality. Temperatures aren’t increasing, storms are down in number and strength, sea levels aren’t chasing folks from beaches, droughts are not increasing, parts of the world are growing greener.

“I don’t have the answer. Do you?”

Calculations Suggest That Global Warming Caused By the Doubling of CO2 Will Be Less Than 0.6K

cropped-bob-shapiro.jpg   By Bob Shapiro

The Global Warming Alarmists who want our government to outlaw fossil fuels (which would crash the US Economy) point to their theory that a doubling of CO2 will cause as much as a 4.5 degree Celsius rise in average global temperatures. This figure is outlandish, especially when compared to what the actual observational records since the end of the Little Ice Age tell us. The DATA say that the rise for a doubling of CO2 would be closer to 1 degree. Some researchers come up with a little higher and some find a little lower response, but generally, the number is around 1 degree.
