Nature ties itself in knots here, and reveals a lot more than they probably meant too, but mostly about themselves rather than about Antarctica. If it’s correct, the implications from this study are pretty big, not that the study will tell you that. The term “Global warming” is tossed under a bus, along with almost all the Antarctic man-made scares of the last two decades. The political nature of Nature is on full display.
This time Nature claims it has found the cause of the Antarctic pause. Apparently this now finally resolves yet another conundrum (fantastic, what!) that was, as usual, not called a conundrum until it was solved. Another secret problem fixed. Where was the press release telling us there was a problem?
Those who said there was a conundrum were just deniers. It’s right there in the press release, paragraph two:
The study resolves a scientific conundrum, and an inconsistent pattern of warming often seized on by climate deniers.
Which rather begs the question: If there was a conundrum then the skeptics who pointed it out were not deniers, but correct. And if there was no conundrum, and deniers were denying something, then this is not […]
Jakobshavn Glacier, Greenland Image: NASA
The Jakobshavn is the glacier that dumps more ice in the ocean than any other in the Northern Hemisphere. It made the iceberg that “sank the titanic”. It has been receding for years, and the losses were accelerating, but then it astonished the scientists.
“At first we didn’t believe it,” said glaciologist Ala Khazendar of NASA’s Jet Propulsion Laboratory. “We had pretty much assumed that Jakobshavn would just keep going on as it had over the last 20 years.”

“That was kind of a surprise. We kind of got used to a runaway system,” said Geological Survey of Denmark and Greenland ice and climate scientist Jason Box. “The good news is that it’s a reminder that it’s not necessarily going that fast. But it is going.”
Box, who wasn’t part of the study, said Jakobshavn is “arguably the most important Greenland glacier because it discharges the most ice in the northern hemisphere. For all of Greenland, it is king.”

A map of the sea surface zone that has cooled since 1979 — from 56S – 72S . It’s a pretty big area. Click to enlarge.
For years the IPCC have said that warming would be amplified at the poles. They warned us things would heat up twice as fast, which would melt sea ice. The oceans surface in turn would switch from being reflective white to a dark absorbing deep blue. Enormous amounts of energy would then flow into the ocean instead of being reflected back out to space. The more it warmed, the more it would warm — unleashing a devastating feedback loop.
As the Arctic warmed, the merchants of doom were keen to tell us how how right they were and this was evidence of man-made warming. But in the Antarctic exactly the opposite trend was taking place.
Mike Jonas has done what the IPCC should have been doing — investigating the trends in the Sea Surface Temperature in the polar latitudes with satellite records. In the latitude band from 56 to 72 degrees south the oceans have cooled, not warmed. The models don’t even have the sign of the trend correct. At the latitudes where […]
Let this go down as a prime example of Big Meaningless Numbers used to scare you:
Antarctica’s ice melts five times faster than usual Ben Webster — The Times (copied at The Australian)
Antarctica has lost an area of ice the size of Greater London since 2010 as warmer ocean water erodes its floating edge, a study has found. Overall about 1,463 sq km of Antarctica’s underwater ice melted between 2010 and 2016.
What does 1,463 fewer square kilometers of ice mean?
The findings suggest that melting glaciers on the continent could add significantly to long-term sea level rises, with severe implications for thousands of coastal towns and cities.
Your house might wash away. Or not. How close to zero can a number be and still be “a number”?
The total area of Antarctic sea ice averages about 11 million square kilometers. So that’s one part in 7,500 that melted or 0.013%. But volume is what matters and the percentage of volume that melted is even smaller. Let’s assume ice volume was lost to a depth of one kilometer (the depth of the “grounding line” where the ice-sheet meets the earth). The giant Antarctic Ice Sheet […]
Spot the political PR paper pretending to be science: the global carbon budget just got a whopping — four — times — bigger, but instructions on how to follow the carbon religion are 100% identical.
It’s become too obvious to everyone that the climate models have been complete failures. Thus, the global leeches were facing a crisis as their credibility and motivation drain. So the new paper in Nature Geoscience is just a retweak of the models to produce a number that isn’t so mock-worthy. There is no scientific reason offered, no new understanding of the climate. No one is even pretending that these modelers can explain the way our climate works any better than they did last year when they were utter failures. It’s all a charade. There is no honesty here — if there was, they’d admit the skeptics are years ahead of them.
The new paper is just about “staying the game”, a desperate injection to keep the dying movement alive. All the political messages remain untouched. It’s got everything to do with PR and nothing to do with science.
The numbers change (and nobody ever cared about them anyway) but PR meme is a carbon copy: […]
Overnight a river in Northern Canada disappeared. A glacier had retreated and allowed the water upstream to sneak out via a different path. The water now ends up in the Pacific 1300 km away from the Bering sea where it used to emerge.

You might think this event has happened every time glaciers retreated in the last 30 million years, but you would be wrong. Really, this is due to coal-fired power stations.
In a report published on Monday in the journal Nature Geoscience, Dr. Shugar and his colleagues provide a detailed analysis of how an atmosphere warmed by fossil-fuel emissions has led to the river’s dramatic disappearance.
“To me, it’s kind of a metaphor for what can happen with sudden change induced by climate,” said John Clague, who holds a chair in natural hazard research at Simon Fraser University and was a co-author on the report.

The same modelers were predicting drought and letting their friends nail their reputation to statements about how the dams would never fill, and Perth would be a ghost town. When Australia wasted billions on desal, they said nothing about the “extreme rain” coming. Then the endless drought broke, the rains returned, and now, years later, they’ve rejigged and tweaked their skillless models and put forward ambiguous, vague, yes-no-maybe, scare-scare-scary predictions that could have come from a tarot card reader.
Get ready for the full genius of expert modelling:
“There is no chance that rainfall in Australia will remain the same as the climate warms,” said an author of the paper UNSW Professor Steve Sherwood.
“The only way that this intensification of extreme rainfall falls at the lower end of the scale is if the continent becomes drier overall. The long and the short of it is that with 2°C of global warming Australia is stuck with either more aridity, much heavier extreme rains, or some combination of the two,” said Sherwood, from UNSW’s Climate Change Research Centre.

BREAKING: Massive magnitude 7.9 earthquake hits New Zealand tonight at midnight local time. 90km North of Christchurch. Thankfully, so far there are no reports of injuries or deaths. UPDATE: One Two deaths now reported. The quake was rated 7.4 initially but upgraded to 7.9 by Geoscience Australia. The small tsunami is expected to reach Australia around now (3 – 4am AEST). Many New Zealanders were evacuated and moved to higher ground for fear of the tsunami estimated at 2.5 – 5m. For more see NZ TV News and Twitter: #Earthquake. Maybe it’s connected to the full moon, maybe it isn’t. Best wishes to all our New Zealand readers.
UPDATE: Another strong 6.4 Earthquake has hit NZ, and a lot of small ones.
UPDATE: Clarence River got blocked, a lake formed, and has breached due to the quake. There were possibly two simultaneous quakes at midnight last night. In 2010 the fault rupture was about 30km long. This time it was about four times as long (about 3:30ish on the video). There have been over 400 aftershocks small earthquakes. h/t Tom.
UPDATE: NZ Geo’s say the big quake was 7.5. They are clocking up the aftershocks by the minute […]

Here on the ball of magma called Earth, there’s a hot plume of rocks under Iceland that stretches right across under Greenland. Those hot rocks are melting the ice from below in a band 1,200 km long and 400 km wide.[1]
I don’t think solar panels are going to stop Greenland melting.
The main part of the plume has been progressing eastward over the last 120 million years, right under Greenland and now lies under Iceland.
Will the media take a million years to catch on?
Presumably, being world class journalists, from now on all ABC/BBC/CBC stories will not mention melting Greenland ice-sheets without also noting that geothermal heat may be causing it instead of your long hot showers.
But a similar study published in Nature Geoscience 3 years ago was the forerunner to this one with similar conclusions and the mainstream media don’t seem to have noticed yet.[2] No mention of magma, tectonics and hot rocks here: ABC — Antarctica’s melting ice alone could lift sea levels one metre by 2100, March 31st, 2016. Or here: ABC — Global warming melts last stable edge of Greenland’s Zachariae ice stream, March 17th, 2014. Or on the BBC – […]
We’re launching headlong back into the New Science series with a major post
Lots of things will fall into place — as befits a potential paradigm step forward. For decades, people have been looking to see if the Sun controlled our climate but the message was perplexingly muddy. In the long run, solar activity appears linked to surface temperatures on Earth. (Solar activity was at a record high during the second half of the 20th century when temperatures were also high.) But when we look closely, firstly the solar peaks don’t exactly coincide with the surface temperature peaks, and secondly, the extra energy supplied during the solar peaks is far too small to do much warming. So how could changes in surface temperature be due to the Sun?
A few researchers noted an esoteric correlation of long solar cycles with lower temperatures in the next solar cycle, but mostly those papers were left on the shelf, ignored. Dr David Evans’ notch-delay solar delay theory can explain this odd pattern.
To unravel the connections David took a new approach which cleared out the dead-end complexity of the current climate research. Instead of trying to predict everything from a bottom […]
This new paper by Adophi et al uses beryllium, oxygen and carbon isotopes from Greenland ice cores right back as far as the depth of the last ice age, 22,500 years ago, and finds there is a link between solar activity and the climate. It follows these proxies of temperature and solar activity as the planet warmed to the start of the Holocene 10,000 years ago.
It is gaining attention in The Daily Mail, with the headline:
Is the SUN driving climate change? Solar activity – ‘and not just humans’ – could be increasing global warming, study claims
During the last glacial maximum, Sweden was covered in a thick ice sheet that stretched all the way down to northern Germany and sea levels were more than 330ft (100m) lower than they are today, because the water was frozen in the extensive ice caps.
‘The study shows an unexpected link between solar activity and climate change,’ Dr Muscheler said in a press release.
‘It shows both that changes in solar activity are nothing new and that solar activity influences the climate, especially on a regional level.

Flagging an update (coming) to Big News Part III
Score 1 for open science review, thanks to Bernie Hutchins, an electrical engineer who diligently asked the right questions about something that bothered him regarding the notching effect. We’re grateful. This will improve the model. On the downside, it means we’re slightly less certain of the delay (darn) — the notch doesn’t guarantee a delay as we had previously thought. But there is independent evidence suggesting temperatures on Earth follow solar activity with a one cycle delay — the lag seen in studies like Archibald, Friis-Christainsen and Usoskin is still a lag.
What does it mean? The step-response graph (figure 2 in Part III or figure 4 in Part IV) will change, and needs to be redone. The reason for assuming there is a delay, and building it into the model, rests now on the independent studies, and not on the notch. The new step change will need to be built into the model, and in a few weeks we’ll know how the predictions or hindcasting change. David feels reasonably sure it won’t make much difference to the broad picture, because a step-response something like figure 4, Part IV, explains global […]
The Solar Series: I Background | II: The notch filter | III: The delay (you are here) | IV: A new solar force? | V: Modeling the escaping heat. | VI: The solar climate model | VII — Hindcasting | VIII — Predictions
UPDATE: July 21 Thanks to Bernie Hutchins, David found a problem with the code, which means the notch no longer guarantees a delay. The delay still likely exists (see the other evidence in the references below) but this post, particularly figure 2 needs correction and updating. – Jo
Strap yourself in. The Notch in the Earth’s response to incoming solar energy means that every 11 years (roughly) the solar energy peaks, and at the same time the climate’s response to the extra energy changes. What on Earth is going on?
The thing about notch filters that is hard for anyone who isn’t an electrical engineer to understand is that it appears to start working before “the event” it is filtering out. This is obvious in the step response graph. That’s Figure 2 – which shows what happens where there is a […]
A new paper (Moffa-Sánchez et al) reports that they looked at layers of dead plankton in ocean mud (otherwise known as foraminifera in marine sediments) and have reconstructed the temperature and salinity of a couple of spots in the North Atlantic between 818AD – 1780 with data on δ18O and the Mg/Ca ratios. One immediate thought, an aside, is that if this technique works, there is no shortage of ocean mud, surely, and perhaps we could drill and analyze more mud for solar correlations in other places. (I hear foraminifera live in the Southern Hemisphere too). Perhaps no one is looking for the connection with the sun?
Moffa-Sánchez et al find the big climate shifts (the 100-year variations) correlate with total solar irradiance (TSI). See especially that orange line black line track in the d graph below. I stress, correlations don’t mean causation and the mechanism is mere speculation. But I find the graph intruiging. There are a lot of turning points, and in pure “curve fitting” type of analysis, this is a better curve fit than the one with CO2. (Find me a turning point that matches with carbon dioxide!) I suspect we’ll be referring back to this paper, […]
Proving that nature can outdo anything humans have done, a new paper shows that sea-levels off Western Australia may have risen as high as 9 m above the current level during the last warm period over a hundred thousand years ago. The authors (O’Leary et al) conclude that seas were 3-4 m higher for most of the last warm period (known as the Eemian) but towards the end of the period a large sudden rise occurred. They suggest that an ice shelf collapsed in Antarctica or Greenland or both, causing a 5m rise (17 feet).
The point of the paper was this double spiked shape of the sea level rise during the last warm interglacial known as the Eemian.
The Age interviewed O’Leary who said “he was confident that the 17-foot jump happened in less than a thousand years – how much less, he cannot be sure.”

Ageomorphically defined palaeoMSL datum of C2:5m 120 kyr ago (Fig. 1c) anchors a predicted relative sea-level curve at Red Bluff, which includes a GIA signal based on the test calculation (see Methods) plus the following ESL history: ESL jumps from 0 to 3.4m […]
Here are the questions Tony Jones could have asked if only he or his billion-dollar organization had the time to use the Internet. Is he a journalist or an activist pretending to be one?
And how much does Jones get paid by the taxpayer for allowing McKibben a free pass to say things that are easily shown to be false? The ABC wants to keep that a secret. It wants your money, but not your opinion.
The full transcript is on the ABC site, I’ve selected parts below. (My cost to the taxpayer: $0).

“Stop investing in carbon intense industries”
TONY JONES: Let’s start with the statement most frequently used by climate change sceptics: the planet has stopped warming since 1998 and started to cool, actually cool, since 2003. True or false?
[Tony Jones is offering a blatantly false position for McKibben to knock over…. skeptics most frequently point out that there has been no significant warming (there are 350 million google results for that compared to 10 million for global cooling since 2003). The UK Met office, and the head of the IPCC say the same thing. The issue that matters is the “pause” that […]
The mouth of the Amazon is the worst source of “pollution”.
Bad news for fans of The Amazon River. A new study shows that while the Amazon rain forest is the Lungs of The Planet, pulling down gigatonnes of CO2, the river undoes all the good the trees do, and pours all the CO2 back into the sky. Damn that river eh? Lucky it only discharges one fifth of the worlds freshwater.
Apparently most researchers thought bacteria couldn’t digest the tough woody lignin of tree debris fast enough to prevent it getting to the ocean*. Underestimating microbial life seems a common affliction, and we hear was a big surprise that only 5% of the lignin actually ends up reaching the ocean where it might sink to the floor and be sequestered. The rest is broken down by bacteria and released into the air. The clues were there for years that the Amazon was giving off lots more CO2 than people expected, but the consensus was that it “didn’t add up”. So much for that consensus.
Yet another victory for observations over opinions.
Until recently, people believed much of the rain forest’s carbon floated down the Amazon River and ended […]
Finally the modelers are catching up with the slow-down or pause in global warming over the last decade. Where the best estimate for the IPCC was 3.3 degrees C with a range of 2.0 to 4.5C, Otto et al have revised the best estimate to 2C, with a range of 1.2C – 3.9C.
Effectively the power of CO2 to warm just got 30% less, according to a team of researchers, many of whom have in the past have published more alarming papers. Remember “there is no debate” and “global warming is a fact” a lot “like gravity”. (And that gravitational constant g could be revised by a third soon, right?)
The Australian writes it up as “TEMPERATURE rises sparked by increased carbon dioxide levels will be lower than previously thought, an international research team has found”. The Age tells us that disaster is still coming but it will be slower. “Warming to take longer in reaching forecast levels”.
Otto et al looked at the global energy budget which means adding up atmospheric, ice, continent, and ocean energy. They compare it decade by decade since 1970, and argue that the long term equilibruim temperature response need to be revised down. The […]

Despite the fuss about CO2 emissions, on a global scale no one is quite sure where a lot of it ends up. Those mystery “sinks” draw in a large proportion of CO2. Here’s a big sink that just got twice as big.
Science Daily Mar. 17, 2013 — Models of carbon dioxide in the world’s oceans need to be revised, according to new work by UC Irvine and other scientists published online Sunday in Nature Geoscience. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, they found. Global marine temperature fluctuations could mean that tiny Prochlorococcus and other microbes digest double the carbon previously calculated.
The trouble started when someone made an assumption.

For all the data we can scrape out of rocks, shells and cylinders of ice, what we really need to know, in detail on a planetary scale, is how much energy comes in and how much goes out. That can only be measured (even roughly) with satellites.
This paper rattles the whole table of key numbers, with empirical results. It puts core numbers into a new perspective, numbers like the 3.7Watts per square meter that a doubling of CO2 is supposed to add to the surface budget.
The models are hunting for imbalances and build-ups in planetary energy. But according to the observations, the longwave (infra-red) energy coming onto the earth’s surface, the infamous back radiation, is 10 – 17 W/m2 higher than in the famous Trenberth diagram from 1997. So the models are trying to explain tiny residual imbalances, but the uncertainties and unknowns are larger than the target. The argument that “only the forcing from CO2 can fill the gap in the models” is not just argument from ignorance rhetorically, but factually too.
Another major implications is that water is churning up and falling out of the sky faster than the experts thought. The Earth’s evaporative cooler is […]
