New study claims low solar activity caused “the pause” in global temperature – but AGW will return!

Anthony Watts:

This is on a tip from Dr. Leif Svalgaard, WUWT’s resident solar expert. It was just published in the journal Atmospheric and Climate Sciencesand is open access. I found this study’s conclusion a bit amusing, because there are numerous claims that solar activity (and the slight increase in TSI seen in the last 30 years) can’t explain the global warming we’ve seen, but yet somehow the recent period of low solar activity can explain the pause, and when solar activity resumes, global warming will return anew. Dr Svalgaard gives the author, Peter Stauning, high marks for his work in general, but disagrees with him on this paper.

I’m also more than a little bit puzzled how the journal editor and the peer reviewers let this sentence pass, everybody makes typos, but this one takes the cake. I kid you not:

But secondly, there must be a fair global coverage such that localized climate variations like the North-Atlantic Oscillation (NAO), or the El Ninjo/La Ninja in the Pacific would not affect the result too much.

Yes, I really want to see what the La Ninja effect looks like.

Here’s the paper abstract and excerpts:

Reduced Solar Activity Disguises Global Temperature Rise
DOI: 10.4236/acs.2014.41008  Author: Peter Stauning

ABSTRACT

The question whether human activities seriously affect climate is asked with increasing voice these days. Quite understandable since the climate appears to be out of control with the significant global temperature increases already seen during the last three decades and with still heavier temperature increases to come in the future according to prognoses, among others, in the recent comprehensive IPCC reports [1].

AGW isn’t about science…it’s about faith.

Faith in science perhaps. Less than 0.01% of peer-reviewed climate articles published in the past 15 years explicitly reject man-man global warming.
Deniers can only point to posts in right-wing blogs in a sad attempt to disprove years of scientific consensus in published academic journals with rigorous standards of review. So which side is relying solely on faith? Climate change denial is nothing more than an ideological stance fomented by non-scientists like Rush Limbaugh and Donald Trump and their ilk. Listen to them and ignore the consensus of actual scientists at your own peril.

I have brought my previous study (see here and here) up-to-date by reviewing peer-reviewed articles in scientific journals over the period from Nov. 12, 2012 through December 31, 2013. I found 2,258 articles, written by a total of 9,136 authors. (Download the chart above here.) Only one article, by a single author in the Herald of the Russian Academy of Sciences, rejected man-made global warming.

@Tom: Science is not about consensus. Science is about being able to reproduce results. If you recall, Galileo said the Earth revolved around the Sun while the consensus was that the Sun revolves around the Earth. The consensus was wrong.

The AGW activists credit the low solar activity with a “pause” in warming, but do not credit the solar activity for any warming. That premise lacks reason as does your post!

I was hoping you would come,
do you think the two plane landing on the wrong airport ,
could be link to the sun magnetic activity now in the SOUTH,
conflicting with the Earth magnetic activity aiming north,
LIKE DISTERBING THE MAGNETIC FIELD MAKING THE MANY CLOCKS IN THE DASH
MOVE AWAY OR COUNTERCLOCK,
IT SOUND STRANGE TO ME THAT MANY PLANES HAVE SOME PROBLEMS, SOME DEADLY ALSO,
BYE

Wow, Randy. I don’t even know where to start. You do realize the consensus in Galileo’s time about the Sun revolving around the Earth wasn’t a scientific consensus based upon thousands of peer reviewed studies, I assume? I believe that consensus was based upon religion, the dogmatic adherents of which tend to resist scientific conclusions that clash with their faith, even in our time. No matter how y0u try and parse it, you’ve aligned yourself against the scientific consensus on global warming. Since there is no real research being published to disprove the consensus, the skeptics simply state that the science hasn’t proven it to their satisfaction. I’d be curious if there’s any other branch of science you approach with such open hostility and heightened suspicion. How did you arrived at this conclusion about climate science, while presumably taking other scientific consensuses for granted?

As for reproducing results, the models used by climate scientists do reproduce them, initially through hindcasting, and then later, in real time:
http://www.skepticalscience.com/climate-models.htm

Climate models are mathematical representations of the interactions between the atmosphere, oceans, land surface, ice – and the sun. This is clearly a very complex task, so models are built to estimate trends rather than events. For example, a climate model can tell you it will be cold in winter, but it can’t tell you what the temperature will be on a specific day – that’s weather forecasting. Climate trends are weather, averaged out over time – usually 30 years. Trends are important because they eliminate – or “smooth out” – single events that may be extreme, but quite rare.

Climate models have to be tested to find out if they work. We can’t wait for 30 years to see if a model is any good or not; models are tested against the past, against what we know happened. If a model can correctly predict trends from a starting point somewhere in the past, we could expect it to predict with reasonable certainty what might happen in the future.

So all models are first tested in a process called Hindcasting. The models used to predict future global warming can accurately map past climate changes. If they get the past right, there is no reason to think their predictions would be wrong. Testing models against the existing instrumental record suggested CO2 must cause global warming, because the models could not simulate what had already happened unless the extra CO2 was added to the model. All other known forcings are adequate in explaining temperature variations prior to the rise in temperature over the last thirty years, while none of them are capable of explaining the rise in the past thirty years. CO2 does explain that rise, and explains it completely without any need for additional, as yet unknown forcings.

Where models have been running for sufficient time, they have also been proved to make accurate predictions. For example, the eruption of Mt. Pinatubo allowed modellers to test the accuracy of models by feeding in the data about the eruption. The models successfully predicted the climatic response after the eruption. Models also correctly predicted other effects subsequently confirmed by observation, including greater warming in the Arctic and over land, greater warming at night, and stratospheric cooling.

@Tom: You are a real asset to F.A. “Stay thirsty my friend.”

Tom
very good reading your page,
you should be aware for comming here often,
that RANDY know already more than you on climate,AND ON SOME FALSE SCIENTIS’S PREDICTIONS,
ON CLIMATE AND on magnetic interference
between sun and the earth magnetic field, and what ever else you study,
RANDY HAS SHOWN HIS KNOWLEDGE TO US MANY TIMES FOR US TO BELIEVE WHAT HE SAIS,
BEFORE ANYONE ELSE,
BYE

Guess it’s almost crazyville here, huhh?

JIM CRANE
YES,

THE ACTIVIST ARE SO FULL OF THIS , THEY THINK THEY HAVE BEEN GIVEN THE KEY TO CLIMAT CHANGE AN OR TO GREEN SCIENCE WHICH IS A WELL PAID SCIENCE, FULL OF MADE UP LIES,
WHICH THEY GET BACK IN THEIR FACE AFTER SOMEONE DEBUNK THEIR BELIEF,
THEY ARE RESPONSIBLE FOR OBAMA CLOSING THE COAL MINES IN THIS AMERICA, today,
AND THEY ARE RESPONSIBLE FOR THE MULTI MILLION BIRDS OF ALL SIZE DEATH WITH THOSE
HIGHT VIBRATING WIND TOWERS, THEY ARE RESPONSIBLE FOR INFLUENCING OBAMA IN DELAYING MANY JOBS AND WEALTH FOR not BACKING THE KEYSTONE PROJECT FROM CANADA,
TO BUILD TUNNEL FOR DIRECTING THEIR OIL ALL OVER THE USA,; BRIGNING MORE WEALTH AND JOBS, THEREFOR THOSE ACTIVIST ARE A PAIN IN THE NECK OF THE USA,
FOR THIS BROKEN ECONOMY AND THE AND THEIR FAMILY,
damn the activist,
