Roy Spencer on ‘Santer takes on Pruitt’

US Environmental Protection Agency (EPA) chief Scott Pruitt

As Dr Roy Spencer points out: ‘You can’t build a case for human-caused warming by relying on natural warming! (But, they did anyway.)’

A new paper in Nature: Scientific Reports by Santer et al entitled Tropospheric Warming Over the Past Two Decades begins with this:

After a recent Senate confirmation hearing, Scott Pruitt the new Administrator of the U.S. Environmental Protection Agency received a written question regarding observed warming estimates. In response, Mr. Pruitt claimed that over the past two decades satellite data indicates there has been a leveling off of warming. We test this claim here.

Now, exactly how does one scientifically test a claim of “leveling off of warming”?

UK braced for drought after ‘excessively dry’ April

Contrasting weather situations for the UK and the US, post El Niño. Even the wettest place in England is ‘bone dry’.

There are fears the UK could be braced for widespread drought this summer after “excessively dry conditions”, says ITV News.

The Environment Agency said the UK saw just 35% of its normal rainfall in April and farmers have been warned crops could fail.The unusual weather spell follows the driest winter since 1995-1996.

Minette Batters, Deputy President of the National Farmers’ Union, told ITV News: “I think many of my farming colleagues in East Anglia, in the south east are seeing excessively dry conditions.”

Farmer James Winslade told ITV News: “Arable farmers, grass farmers, dairy farmers – it doesn’t make any difference. They’re all worried. They’ve all cut grass earlier than they normally would have done and we haven’t had the rain to get the grass and crops growing back”.

How the recent El Niño saved climate models

Once the El Niño crutch is kicked away, what have climate models got left in terms of warming apart from ‘the pause’? Not a lot, according to this analysis.
H/T GWPF

El Ninos can be used to make computer climate models look better than they are, for a short time at least, says Dr. David Whitehouse.

The message one is trying to get across when communicating science can depend much on what one doesn’t say. Leaving something vital out can make all the difference and when it’s done it can make scientists look like politicians, although not sophisticated ones.

As an example of what I mean consider the El Niño phenomenon – a short-term oceanographic weather event. The El Niño can be used to make computer climate models look better than they are, for a short time at least.

Forecasters predict El Niño may return by summer

The El Niño of 1997-8

The report says ‘the possible return of El Niño this year would present a unique situation’. Is there still excess heat in the system as sunspots go further into ‘quiet mode’?
H/T GWPF

The path to another round of El Niño in 2017 appears to be shortening, as tropical Pacific Ocean waters have been warming at a substantial rate. Several models suggest that El Niño could be comfortably in place as early as May.

Weather forecasters have been eyeing for a couple of months a possible return this year of El Niño, which normally comes around every two to seven years and last occurred in 2015/16.

El Nino to El Nino – no net global warming

Comparing the actual data to the forecasts of climate models is also embarrassing for those obsessed with climate warming.

wryheat

The Earth experienced two super El Ninos recently: 1997/1998 and 2015/2016. It was expected that 2016 would be the hottest year in the satellite record which begins in 1979. It was, but by only 0.02°C over 1998. That is not statistically significant according to Dr. Roy Spencer, keeper of the UAH satellite system data. (The margin of error is 0.1°C, much larger than the difference between the El Nino years.) The graph above shows the UAH results. A separate satellite analysis by Remote Sensing Systems (RSS) came to the same conclusion.

Satellites measure the temperature of the lower troposphere, the portion of the atmosphere where weather takes place. These measurements give a more realistic picture of global temperature than do surface measurements. Essentially, global temperature now is the same as it was nearly 18 years ago.

The earlier El Nino had a sharp drop off as a strong La…

Record drop in global temperatures as El Niño warming ends

Another round of claims and counter-claims about climate is underway as natural variation takes its course. Talk of records often relates only to the satellite era.
H/T GWPF

Global average temperatures over land have plummeted by more than 1C since the middle of this year – their biggest and steepest fall on record, reports David Rose in The Mail on Sunday. 

According to satellite data, the late 2016 temperatures are returning to the levels they were at after the 1998 El Niño. The news comes amid mounting evidence that the recent run of world record high temperatures is about to end.

I’m going to write here how it all started, but first I like to show my updated recent ENSO data and forecast which I presented at the recent climate conference in London.

Fig 1: ENSO result from my ANN. Training period is from 1979 and up to 2005. The testing period is from 2005 and up to the end of 2015. From 2015 and up to the end of 2022 it is a forecast. The red line is the real ENSO value and dark line is the result I got from the ANN. As you can see the dark line is from the average values from ensemble.

Temperature Variation Due to ENSO

Useful comparison of ENSO and (supposed) CO2 influences on climate by kenskingdom. ENSO correlations look significant, whereas CO2 – nothing to report really.
H/T Climate Depot

In this post I use the Multivariate ENSO Index (MEI) supplied by NOAA at http://www.esrl.noaa.gov/psd/enso/mei/index.html and lower tropospheric temperature data supplied by UAH to show how much of temperature variation over the past 20 years is due to ENSO and how little is due to CO2.  I will keep words brief and let graphics do the talking.

Firstly, here is the MEI data from 1950:

Fig. 1:  Monthly MEI from 1950

As an aside, this is how it compares with SOI data.  The SOI is inverted and both are scaled for comparison.

Fig. 2:  MEI compared with SOI inverted

Now compare scaled MEI with Global UAH:

Fig. 3: MEI (scaled) and UAH

Notice tropospheric temperatures appear to lag the MEI by some 5 months:

Notice both datasets are noisy, and there is a clear discrepancy in the early 1990s.  12 month running…

Big Drop In June Temperatures According To UAH

.
.
We’re supposed to believe that CO2 levels determine global temperature, but here in plain sight is obvious evidence that they don’t.

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Roy Spencer has news of a big drop in satellite temperatures last month:

NOTE: This is the fifteenth monthly update with our new Version 6.0 dataset. Differences versus the old Version 5.6 dataset are discussed here. Note we are now at “beta5” for Version 6, and the paper describing the methodology is still in peer review.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2016 is +0.34 deg. C, down 0.21 deg. C from the May value of +0.55 deg. C (click for full size version):

This gives a 2-month temperature fall of -0.37 deg. C, which is the second largest in the 37+ year satellite record…the largest was -0.43 deg. C in Feb. 1988.

In the tropics, there was a record fast 2-month cooling of -0.56 deg. C, just edging out -0.55 deg. C in June 1998 (also an El Nino…

RJS writes:
The following demonstrates that Metoffice Hadcrut4 is a restatement of the NOAA El Nino index. It’s based on the conjecture that not only do El Nino events have an immediate effect on world temperature but also the clustering of El Nino or La Nina events have a cumulative effect on the worlds temperature. Ian Wilson and Paul Vaughan have provide the frame work to show that El Nino events are governed by the interaction of the Sun and Moon coupled with the hemispherical asymmetry of the Earth’s surface properties. The climate variation is driven by the ratio in strength and frequency of El Nino to La Nina events.

Temperatures Falling As El Niño Fades Quickly

ENSO trend [credit: NOAA]

How much of recent El Nino-backed warming was ‘man-made’, if any? NOAA has issued a La Niña watch so we may well see average temperatures going into reverse before too long.
H/T GWPF

El Niño is quickly fading. Sea surface temperatures are coming down in the tropical Pacific, and winds in the region have weakened. History tells us, and forecast models predict, that La Niña conditions will be quick on its heels.

Modellers of El Niño events get cloud data surprise

Send in the clouds [credit:NASA]

Adding cloud data to climate models must be long overdue if it’s considered to be a new technique. Scientists were surprised to find that doing so accounted for over half the strength of El Niños, as Phys.org reports:

A small team of researchers from the U.S., Australia and Germany has found evidence that suggests cloud formation may have a much bigger impact on weather patterns associated with El Niño events than has been thought.

In their paper published in the journal Nature Geoscience, the team describes they differences they found when they input cloud data into computer models that simulated weather patterns associated with El Niño events and why they now believe that all such models should include such data going forward.

Per Strandberg: ENSO caused by tidal pulses during Perigee and by solar activity

My thanks to Per Strandberg for this update on his ENSO modelling effort. This is looking good, and is based on a neural network which uses lunar and solar data for its input.

There are two main drivers of ENSO. ENSO stands for El Niño Southern oscillation and is Earth’s most influential weather phenomena after seasonal changes. When ENSO changes it causes changes in currents and of temperatures in the tropical Pacific Ocean.

The most important ENSO driver is linked to variations in gravitational tidal forcing associated with Moon’s Perigee. Moon is in what is called Perigee, when the Moon is at it closest point during its elliptical orbit around Earth. This is also when the tidal force caused by the Moon is at its strongest.

The second most important forcing is linked to variation in solar activity.

Cheeky Pukitee: nicking knowledge without acknowledgement

Last week I told Paul Pukite where he was going wrong with his ENSO model:

@WHUT @LittleIceAge You still don't have the prime mover for your oscillation, no matter how you attempt to derail the convo to hide that.

— Rog Tallbloke (@RogTallbloke) September 3, 2015

@WHUT @LittleIceAge And what do you think the prime movers behind tides and the CW are? 😉 QBO is a long way up in the sky, & of tiny mass

— Rog Tallbloke (@RogTallbloke) September 3, 2015

@WHUT @LittleIceAge I did that ages ago. Look: https://t.co/dSw9I1YGmm Tides not mentioned in your abstract by the way…

— Rog Tallbloke (@RogTallbloke) September 3, 2015

This week, he’s ‘discovered’ that The Moon and the tides it raises underlie both The El Nino Southern Oscillation (ENSO) and  the Quasi Biennial Oscillation (QBO), which he previously thought was the driver of ENSO along with the Chandler Wobble (CW), as seen in the tweets above. He hastily added ‘tides’ though they get no mention in his original post.

El Niño is here says NOAA – but only just

Maps of sea surface temperature anomaly [credit: NOAA]

What follows are extracts from the US NOAA’s own blog. They report: ‘After twelve months of El Niño Watches, we are issuing an El Niño Advisory.’ But the conditions are ‘extremely weak’ at this time [note: the maps shown are NOT current conditions]:

Over the last several months, we’ve seen warmer-than-average sea surface temperatures (SSTs) in the tropical Pacific, including the Niño3.4 region, which we track as one indicator of El Niño. The seasonal Niño3.4 Index has been at or above 0.5°C since September, and the most recent weekly Niño3.4 index was +0.6°C.

The El Niño/Southern Oscillation (ENSO) is a coupled phenomenon, though, so we also monitor the atmosphere for signs that it is responding to those positive SST anomalies. For the last few months, we’ve been seeing some suggestions of borderline atmospheric El Niño conditions, but until this month [March] we were below that borderline. This month, we’ve finally crept above it, and thus NOAA is declaring the onset of El Niño conditions.

But what does it mean for North American and global weather?

Paul Pukite: Sloshing Model for ENSO

Scientist Paul Pukite has built a simple model involving Total Solar Irradiance , the Chandler wobble and the Quasi-Biennial Oscillation which does an impressive job of emulating the Southern Oscillation index from Darwin and Tahiti. Here’s the result:

 

Ian Wilson: Evidence that strong El Nino events are triggered by the Moon

Writing from Australia Ian Wilson will be familiar to Talkshop regulars expounding his interest in astronomical connections with earth. He has three related recent articles and now a summary binding them together. Tim adds, the subject has a long history including false accusations of astrology by detractors; in this linked 1999 paper by a veteran scientist some of the origins and history is briefly mentioned and also that as data and computing power becomes available progress is being made. It mentions El Nino [paper see ref 1].  Strangers may need to get a conceptual understanding of the regular alignment of the earth moon and sun, where self evident effect on earth is the cyclic variation is ocean tidal height.

1. A SUMMARY OF THE THREE PREVIOUS POSTS

If you are unfamiliar with this topic you may wish to read the following three post in order to understand this current covering post.

• Evidence that El Nino Events are triggered by the Moon – I
  I . The Changing Aspect of the Lunar Orbit and its
  Impact Upon the Earth’s Length of Day (LOD).

  Tidal Cycle.
• Evidence that El Nino Events are triggered by the Moon – III
  III. Strong El Nino Events Between 1865 and 2014.

Observations of the Earth rate of spin (i.e. LOD) show that there are abrupt decreases in the Earth’s rotation rate of the order of a millisecond that take place roughly once every 13.7 days. These slow downs in spin occur whenever the oceanic (and atmospheric) tidal bulge is dragged across the Earth’s equator by the Moon. They are produced by the conservation of total angular momentum of the Earth, its oceans and its atmosphere.

Role of the oceanic bridge in linking the 18.6-year modulation of tidal mixing and long-term SST change in the North Pacific

S. Osafune, S. Masuda and N. Sugiura
http://dx.doi.org/10.1002/2014GL061737

Abstract

The impact of the 18.6-year modulation of tidal mixing on sea surface temperature (SST) in the North Pacific is investigated in a comparative study using an ocean data synthesis system. We show that remote impact through a slow ocean response can make a significant contribution to the observed bidecadal variation in wintertime SST near the center of action of the Pacific Decadal Oscillation in the eastern Pacific. A comparative data synthesis experiment showed that the modified SST variation is amplified by bidecadal variation in the westerly wind. This relationship between SST and wind variations is consistent with an observed air–sea coupled mode in the extratropics, which suggests that a midlatitude air–sea interaction plays an important role in enhancing the climate signal of the 18.6-year modulation. This result supports the hypothesis that the 18.6-year tidal cycle influences long-term variability in climate; thus, knowledge of this cycle could contribute towards improving decadal predictions of climate.

Has Joe done what Uncle Sam couldn’t?

Some say money can buy brains, brains are cheap. Duffers think that, make the mistake of confusing rote with The Spark. As a wit said ‘the most intelligent person in the room is the room’… to which I add, buying others to inside still leaves the room. Self selection is recursive.

There again for here, an oscillation does not explain itself. Small step first.

A Single Meteorologist Explains What $165 Billion In Government-Funded Climate Science Couldn’t

Large scale oceanic oscillations responsible for most of the post 1980 “warming”

By Joe Bastardi

I think global warming is a misnomer.

There is a distortion of the temperature pattern on the globe, brought about by the natural cyclical warming events of the warm PDO and warm AMO together. I spoke about this at Heartland a couple of years ago – how the sea ice increase in the south and the decrease in the north were the hidden message that here is no “warming” just a distortion.
