Was Global Warming The Cause of the Great Northwest Heatwave? Science Says No.

by C. Rotter, July 6, 2021 in WUWT

Reposted from The Cliff Mass Weather Blog

During the past week, the Pacific Northwest experienced the most severe heat event of the past century.

All-time high-temperature records were broken throughout the region, often by large margins. Many in the media, several local and national politicians, and some activist environmental scientists have claimed that this event was “driven by” or predominantly forced by human-inspired global warming (usually referred to as “climate change”).But such global warming claims are not supported by the facts and our best scientific understanding.  

Truth and Rigorous Science About Climate Change is Necessary for Wise Decisions
In this blog, I will use observations, modeling, climatological data, and the peer-reviewed scientific literature to demonstrate that human-caused global warming played a very small role in the extreme heat event that we just experienced here in the Pacific Northwest.I will describe the origins of a meteorological black swan eventand how the atmosphere is capable of attaining extreme, unusual conditions without any aid from our species.As you read this, consider that I have actively pursued research on Northwest heatwaves, published several papers in the peer-reviewed literature on this specific topic, and have run both weather prediction and climate models that simulate such events.  This subject is in my wheelhouse.

I also discuss the seriousness of misinformation.   You and others can not make wise decisions when the information provided to you is not based on truth and science.

NEW NASA STUDY: SATELLITES SEE COOLING IN THE UPPER ATMOSPHERE

Cap Allon, July 1, 2021 in Electroverse

NASA satellites have revealed that the mesosphere –the layer of the atmosphere some 30-50 miles above our heads– is COOLING and contracting.

Using decades of data and a number of satallites, a team at NASA have identified a cooling mesosphere.

“We had to put together three satellites’ worth of data,” said Scott Bailey, atmospheric scientist at Virginia Tech in Blacksburg, head of the new research, published in the Journal of Atmospheric and Solar-Terrestrial Physics.

“You need several decades to get a handle on these trends and isolate what’s happening,” continued Bailey, who goes on to blame the usual “greenhouse gas emissions” for the observed changes –well how else would they have obtained funding– however, Bailey also mentions “solar cycle changes, and other effects”.

Together, the satellites provided about 30 years of observations, indicating that the summer mesosphere over Earth’s poles is cooling four to five degrees Fahrenheit and contracting 500 to 650 feet per decade.

ACCUWEATHER METEOROLOGIST: GLOBAL WARMING NOT TO BLAME FOR NORTHWEST’S HEATWAVE

by Cap Allon, June 30, 2021 in Elecroverse

Record heat has been felt across the the Pacific Northwest this week, which has led the MSM and their placard-brandishing, sandal wearing EOTW groupies to draw the connection to ‘global warming’ aka ‘the climate crisis’ aka ‘terrifying terra firma broiling’.

However, AccuWeather Meteorologist Joe Lundberg is on the record as saying that AGW isn’t to blame here.

Risking a backlash from his bosses, and from those faceless elites on high, Lundberg very reasonably states: “I just think that right now we’re seeing a very unusual pattern across most of the northern hemisphere where there’s a lot of extremes.”

Lunberg sees erratic jet streams as the main culprit here, which, as Electroverse has been saying for years, are weakening due to historically low solar activity — and while Lunberg doesn’t touch on solar output, he does reference a “big upper level trough that’s in the Aleutians”.

Right now, weather patterns across the country are very unusual, explains Lundberg: “Downstream, there’s a massive upper level ridge that’s in the Northwest, that’s why they’re seeing the record heat there.

“And then downstream along the eastern seaboard, we’re also seeing another upper level ridge.

“But not everyone’s getting this heat,” adds Lundberg — far from it, “across the deep south, for example, it’s actually cooler than average and looks like its gonna stay that way for the foreseeable future.”

Latest GFS runs see temperature departures some 16-20C below the seasonal average across vast regions, particularly in New Mexico:

El Niño and the lengthening New Pause: now 6 years 10 months

by C. Monckton of Brenchley, July 3, 2021 in WUWT

The latest UAH temperature anomalies show that the New Pause has lengthened by another two months to 6 years 10 months. As usual, the Pause is defined as the longest period, up to the most recent month for which data are available, during which the linear-regression trend on the monthly global mean lower-troposphere temperature anomalies shows no increase.

….

Pauses have no predictive purpose. Just because there has been no global warming for more than seven years (HadCRUT4) or almost seven years (UAH), that does not mean there will be no global warming in future.

Heatwave Reporting Shows How Science Has Been Corrupted By Climate Groupthinktch

by A. Watts, July 1, 2021 in ClimateChangeDispatch

The headline in E&E News, WOWT-TV, Scientific American, WorldNewsNetwork, and other media outlets this week, “Unprecedented Heat Wave in Pacific Northwest Driven by Climate Change” couldn’t possibly be more unscientific.

With absolutely no analysis, no historical context, and nothing but conjecture, author Anne. C. Mulkern eschewed science for advocacy in her reporting of the brief Pacific Northwest (PNW) heatwave this week.

Yes, the heatwave set all-time high-temperature records in Washington, Oregon, and Canada. But consider this: At best, we have about 150 years of reliable weather records for the PNW, so a “black swan” outlier eventlike this isn’t surprising.

It’s happened before, most certainly. We just weren’t around to observe it. After all, Native Americans did not keep written weather records.

High- (and low-) temperature records are nothing new. But it is important to look at the past because data shows us that more high-temperature records were set during the first half of the twentieth century than during the past 50 years.

Even the Environmental Protection Agency (EPA) confirms this.

SANTA CATARINA, BRAZIL LOGS ITS THIRD CONSECUTIVE DAY OF RARE SNOW AND SUB-ZERO COLD

by Cap Allon, July 2, 2021 in Elecrroverse

Santa Catarina recorded snowfall in Urupema and Sao Joaquim on Wednesday — the third consecutive day of the rare phenomenon, which also included unusually chilly sub-zero temperatures.

Santa Catarina is the southernmost state of Brazil.

Temperatures across the state have plunged to a record-challenging -7.5C (18.5F), and beyond, this week, and heavy snow has been registered.

According to the Information Center of Environmental Resources and Hydrometeorology of Santa Catarina (Epagri / Ciram), this is the first year since 2000 that snow has been recorded on three consecutive days.

As reported by riotimesonline.com, plunging temperatures and favorable humidity levels have brought substantial accumulations of snow to the towns and cities located in and around the Santa Catarina Mountains

UAH Global Temperature Update for June 2021: -0.01 deg. C

by Roy Spencer, July 3, 2021 in WUWT

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2021 was -0.01 deg. C, down from the May, 2021 value of +0.08 deg. C.

REMINDER: We have changed the 30-year averaging period from which we compute anomalies to 1991-2020, from the old period 1981-2010. This change does not affect the temperature trends.

The linear warming trend since January, 1979 remains at +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).

Greenland Temperatures & The AMO

by P. Homewood, June 13, 2021 in NotaLotofPeopleKnowThat

It’s not new, but it’s worth going over it again.

We have seen how Greenland temperatures rose sharply in the 1920s, and remained at levels similar to the last decade until the 1960s, when they fell equally sharply. This change in climate is closely interlinked with the Atlantic Multidecadal Oscillation (AMO), which switches from cold to warm phase, and back again, roughly every 50 to 60 years:

US Government Tries To Erase Historical Forest Fire Data To Fabricate Another Fake Crisis

by P. Gosselin, June 8, 2021 in NoTricksZone

The US government deletes more than 50 years of early data on forest fires in order to make it look like forest fires are more widespread, and linked to CO2. Should be Investigated under the RICO Act. 

There’s a reason why Smokey the Bear has been around more than 75 years with his message. “Only you can prevent forest fires.” The US government had known for decades that forest fires were a serious problem – much more serious than today.

They have forest fire data going back over 100 years. But suddenly, since January of this year, the US government is acting like there had never been a Smokey the Bear before 1983 and that forest fires are just a recent problem caused by manmade climate change.

It’s all a fraud, explains data analyst and software expert Tony Heller in his latest video.

CARBON CYCLE

by C. Spencer, June 7, 2021 in WUWT

The increase in 12C in the atmosphere is, in my opinion, weak evidence that the annual increases are driven only by fossil fuel sources. The atmosphere can’t tell ‘anthropogenic’ carbon dioxide from natural carbon dioxide. It seems unlikely that a source that represents only about 4% of the total flux is going to drive the system. The oceans sequester the vast majority of the carbon. One would expect that warming oceans (from whatever forcing) would increase the rate of out-gassing in mid-latitudes, and decrease the rate of extraction at high-latitudes. It seems more reasonable to me that, in a world with warming oceans, there would be a shift in the relative amounts of carbon in the oceans and the atmosphere. That would be the case even in the absence of any anthropogenic carbon.

The Manichean Mann

by M. Hulme, June 2021 in IssuesinSci&Techn

Michael Mann has been in the climate wars for well over a decade now. As he reminds us frequently in this new book, he has been in the crosshairs of his enemies, has fought off the attack dogs, and carries the scars of battle. Even the environmentalist Bill McKibben’s promotional puff for the book valorizes Mann in terms of his “scars from the climate wars.” The military framing of climate change long predates Mann’s involvement, but it certainly is a framing he has done much to promote through his blogs, tweets, and general persona-at-large in public discourse.

And so it is not surprising that Mann’s new book continues his characterization of the politics of climate change through a series of complex military tropes and metaphors. Wars, battles, attacks, fights, and enemies litter its 260 pages. Much of what I said about Mann’s combative militancy in my review of his 2012 book, The Hockey Stick and the Climate Wars: Dispatches from the Front Lines, can be equally applied to this new one. Now, his central argument is that there is a new war afoot. The old war—fought mostly around the claims of climate scientists—has been (largely) won. But a new war has been ignited; Mann and his allies are now having to fight against the forces of inaction.

Mann is half right in his diagnosis. The main axes of public dispute and argumentation about climate change have changed. The politics of climate change manifest differently now than they did a decade ago. More centrally in focus—and this is a good thing—are the substantive and pressing questions about the sorts of actions, policies, and interventions that are needed, appropriate, and effective to attenuate the risks of a changing climate. What are their respective costs and benefits? How do different options interact with diverse cultural values and collide with vested interests? How do they complicate international geopolitics?

So in this observation Mann is correct. The focus of the issue has moved from “is there a problem?” to “what should be done about it?”

No sign of a climate emergency

by GWPF, May 29, 2021

A new review of weather and climate data based on observational data from 2020 finds little evidence to support the idea of a “climate emergency”.

 

The annual report, by Professor Ole Humlum, reviews a wide range of temperature and weather data, as well as records on sea-level, storms and ice and snow cover.

Temperature records for the Earth’s surface show that 2020 was a comparatively warm year, but that by the end of the year there was a marked cooling driven by natural ocean cycles in the Pacific. This cooling was also observed higher in the atmosphere.

Sea ice levels globally remained low, but are now increasing in the Southern Hemisphere. Global snow cover remained stable and there is still no significant trend in tropical storms.

Professor Humlum said:

The weather and weather extremes we are experiencing are still dominated by natural fluctuations. Rapid and frightening changes are nowhere to be seen in the observational data as this annual review shows.”

MONTHLY LOW TEMPERATURE RECORDS FALL IN VANUATU, AS LATE-SEASON SNOW AND UNPRECEDENTED COLD SWEEP TORONTO, CANADA

by Cap Allon, May 29, 2021 in Electroverse

The “crazy conspiracy theorists” are being proved right, again. But it was never crazy conspiracies that were being theorized. The outspoken few were merely “applying logic” — a skill the impaired herds were educated out of a long time ago, as children, in the indoctrination stations known as schools.

The world is corrupt — most people are all too happy to agree with this statement.

We are being lied to at every corner of life— yet most people struggle with this one.

MONTHLY LOW TEMPERATURE RECORDS TUMBLE IN VANUATU

Following on the heels of New Zealand’s all-time cold, record lows are now sweeping the Y-shaped South Pacific Ocean archipelago of VANUATU–which consists of roughly 83 volcanic islands and stretches approx. 1,300 kilometres.

On May 27, the mercury sank to 14.3C (57F) at Pekoa Airport, located on Espiritu Santo Island

On May 28, a low of 12.5C (54.5F) was registered at the Port Vila Airport, situated on Efate Island.

Both readings are new record lows for the month of May.

LATE-SEASON SNOW AND UNPRECEDENTED COLD SWEEP TORONTO, CANADA

May 28 was a historic ‘double-whammy’ of a day in Toronto, Canada.

First off, the day entered the weather books as the city’s coldest May 28 ever recorded, according to Environment Canada warning preparedness meteorologist Peter Kimbell.

The daytime high had only reached a frigid 4C (39.2F) by Friday afternoon.

For the next coldest May 28 you have to turn all the way back in 1889, according to books for downtown Toronto dating back to 1840. In other words, it’s been 130 years since Torontonians have suffered a May 28 this cold.

“Likelihood Of A Sub-Cooled Summer For Europe In 2021”, Hale Solar Cycle Suggests

by Dr Ludger Laurenz, May 30, 2021, in NoTricksZone

So far, much of Europe has seen a cold and wet 2021. It may be related to solar cycles. 

An essay at Die kalte Sonne by Dr. Ludger Laurenz looks at the relationship between solar activity and weather trends, and believes this summer’s temperature will be 1.5°C lower.

There are many scientific opinions about solar activity’s impact on weather and climate, which differ and contradict each other. For example, a new publication by Leamon et al. provides an important building block for uncovering solar influence. Background here.

Solar influence in historical climate data substantiated

In the Leamon et al publication, the authors looked at the 22-year Hale solar cycles and saw it is possible to detect and substantiate solar influence in historical climate data (from tropical ocean surface temperature to temperature, sunshine, and precipitation data) and to make quantitative statements about the influence of solar activity on weather data.

Norway winter temperature and sun: “high statistical significance”

“Using the alternating years between Hale cycles, a correlation between the 22-year Hale cycle of the Sun and the trend of winter temperature in the polar night of Norway can be demonstrated with high statistical significance,” Dr Laurenz adds.

“Parallel to the temperature trend, the solar influence of the Hale cycles is also evident in the index values of the North Atlantic and Arctic Oscillations,” says Laurenz  in addition. “Evidence of the influence of solar activity in the polar night of Scandinavia demonstrates that differences in solar activity are transmitted to the near-surface temperature via amplification mechanisms such as change in circulation patterns in the North Atlantic and Arctic Oscillations.”

The sun’s role in weather patterns is a great significance, and so CO2 is not the main driver at all.

CO2 Cyclone Doomsday Flat Out Refuted: 170 Years “Absolutely No Trend” In Hurricane Intensity/Frequency

by P. Gosselin, May, 22, 2021 in NoTricksZone

The latest comes from statistics expert, Zoe Phin, who looks at the alarmists’ claim that increasing CO2 emissions are leading to more frequent and intense Atlantic hurricanes.

Alarmist claims cost nothing, and so easily made. Zoe Phin looks at whether the hurricane alarmist claim holds up.

Frequency

First Zoe looked at the (HURDAT2) data to find out if the first of the two claims (increasing frequency) is true. At first glance it would appear so.

But Zoe asks if the method of measuring the frequency really is sensible and if it maybe weren’t better to measure the amount of time the Atlantic spends in hurricane mode? To find out, Zoe plotted the hurricane hours data and the 10-year moving average:

New Study Casts Doubt On Controversial Theory Linking Melting Arctic To Severe Winter Weather

by P. Voosen, May 13, 2021 in ClimagteChangeDispatch

Every time severe winter weather strikes the United States or Europe, reporters are fond of saying that global warming may be to blame.

The paradox goes like this: As Arctic sea ice melts and the polar atmosphere warms, the swirling winds that confine cold Arctic air weaken, letting it spill farther south.

But this idea, popularized a decade ago [and was the outlandish plotline in The Day After Tomorrow, pictured], has long faced skepticism from many atmospheric scientists, who found the proposed linkage unconvincing and saw little evidence of it in simulations of the climate.

Now, the most comprehensive modeling investigation into this link has delivered the heaviest blow yet: Even after the massive sea ice loss expected by midcentury, the polar jet stream will only weaken by tiny amounts—at most only 10% of its natural swings.

And in today’s world, the influence of ice loss on winter weather is negligible, says James Screen, a climate scientist at the University of Exeter and co-leader of the investigation, which presented its results last monthat the annual meeting of the European Geosciences Union.

The Greenhouse Effect In A Water World

by B. Irvine, May 17, 2021 in WUWT

A knowledge of Greenhouse gases is fundamental to any understanding of global surface temperatures. The presence of GHGs in our atmosphere has increased the global surface temperature by about 33C.

There are multiple lines of evidence, however, that challenge the strong water vapour feedback to a small initial CO2 forcing.  These strong positive feedbacks are central to the IPCC narrative.

These lines of evidence include.

  • The failure of all models and catastrophic warming projections.
  • The stubborn refusal of atmospheric Precipitable Water Vapour (PWV) concentration to rise in recent years.
  • The strength of convection cells in the tropics that have kept tropical temperatures approximately the same for many millions of years.
  • Irrigation and extra humidity generally coincide with cooler temperatures.
  • The hot spot as a signature of the positive Water Vapour (WV) feedback and its opposite, the negative lapse rate feedback, has not occurred.

German Professor: Climate Model Deviation From Observations “Striking”…”Politically Significant”

by P. Gosselin, May 8, 2021 in NoTricksZone

At Die kalte Sonne, Prof. Fritz Vahrenholt – one of the founders of Germany’s modern environmental movement – presents his monthly summary, which includes a look at global temperature and how the models are doing.

“The global mean temperature deviation of satellite-based measurements from the mean of the 1991 – 2020 period was -0.05 degrees Celsius in April 2021. Nevertheless, German courts have ruled that something has got to be done about the warming planet!

Global temperature curve in April 2021

The cool La Niña situation over the recent months is still having an effect. According to the U.S. National Oceanic and Atmospheric Administration (NOAA), there is an 80% probability that La Niña will end between May and July. However, the agency expects a new La Niña to begin again in the fall.

The average temperature increase has been 0.14 degrees Celsius per decade. The model calculations, on which the IPCC’s recommendations are based, come up with a temperature increase that is twice as high for the same period (see chart below, source: R. Spencer 2021).

This striking deviation from the real temperature development is politically significant, because model forecasts are the basis for far-reaching decisions, such as constitutional court rulings.”

COSMIC RAY FLUX AND GLOBAL COOLING: THE IMPLICATIONS ARE UPON US

by Cap Allon, Apr 30, 2021 in Electroverse

GALACTIC Cosmic Rays are a mixture of high-energy photons and sub-atomic particles accelerated toward Earth by supernova explosions and other violent events in the cosmos, while SOLAR Cosmic Rays are effectively the same, only their source is the Sun.

Spaceweather.com and the students of Earth to Sky Calculus have been launching cosmic ray balloons almost weekly since March 2015–before the pandemic threw a spanner in. The team’s published results reveal that atmospheric radiation reached record highs just as solar activity hit a new space age low — the correlation is clear for all to see, with additional proxy data revealing it has been the case for time-immemorial.

During solar minimums –the low point of the 11 year solar cycle– the Sun’s magnetic field weakens and the outward pressure of the solar wind decreases. This allows more cosmic rays (CRs) to penetrate the inner solar system, including our planet’s atmosphere:

IT’S GETTING HARDER AND HARDER TO MAINTAIN THE LIE: GLOBAL TEMPERATURES SINK FURTHER IN APRIL

by Cap Allon, May,  3, 2021, in Electroverse

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for April, 2021 has come in at -0.05 deg. C, sinking further below the 30-year baseline down from the March, 2021 value of -0.01 deg. C, and down substantially (approx. 0.65C deg. C) from where we were around a year ago…

…in other words, it is get harder and harder for the politicized ‘catastrophic global heating’ narrative to be maintained. But as Gustave Le Bo writes: “The masses have never thirsted after truth. They turn aside from evidence that is not to their taste, preferring to deify error, if error seduces them. Whoever can supply them with illusions is easily their master; whoever attempts to destroy their illusions is always their victim.”

A continuation of this downward plunge is probable over the coming months (with the odd bump along the way–climate is cyclic after all) as low solar activity and La Nina conditions continues to influence our climate.

According to the 15x NASA/NOAA AMSU satellites that measure every square inch of the lower troposphere (where us humans reside), planet Earth was actually warmer back in 1980:

…

Solar Cycle 25 may have finally started stirring (see link below), but sunspots (a great barometer for solar activity) look set to closely track the forecasts: i.e., the cycle is due to be another weak one, similar in vein to the cycle just gone (24), which will continue the global cooling trend that is now firmly established.

19th century glacier retreat in the Alps preceded the emergence of industrial black carbon deposition on high-alpine glaciers

by M. Sigl et al., Jan 8, 2018 in TheCryosphere

…

Starting around AD 1860, many glaciers in the European Alps began to retreat from their maximum mid-19th century terminus positions, thereby visualizing the end of the Little Ice Age in Europe. Radiative forcing by increasing deposition of industrial black carbon to snow has been suggested as the main driver of the abrupt glacier retreats in the Alps. The basis for this hypothesis was model simulations using elemental carbon concentrations at low temporal resolution from two ice cores in the Alps.

Here we present sub-annually resolved concentration records of refractory black carbon (rBC; using soot photometry) as well as distinctive tracers for mineral dust, biomass burning and industrial pollution from the Colle Gnifetti ice core in the Alps from AD 1741 to 2015. These records allow precise assessment of a potential relation between the timing of observed acceleration of glacier melt in the mid-19th century with an increase of rBC deposition on the glacier caused by the industrialization of Western Europe. Our study reveals that in AD 1875, the time when rBC ice-core concentrations started to significantly increase, the majority of Alpine glaciers had already experienced more than 80 % of their total 19th century length reduction, casting doubt on a leading role for soot in terminating of the Little Ice Age. Attribution of glacial retreat requires expansion of the spatial network and sampling density of high alpine ice cores to balance potential biasing effects arising from transport, deposition, and snow conservation in individual ice-core records.

Dr. Judith Curry sent out a tweet about this article at The Conversation:  “This supermoon has a twist – expect flooding, but a lunar cycle is masking effects of sea level rise“.  The piece is written by Brian McNoldy, a Senior Research Associate, University of Miami and written in conjunction with Covering Climate Now — the climate news propaganda effort headed up by the Columbia Journalism Review and The Guardian.  The Conversation is a member of Covering Climate Now  and a search of their website shows they have published, so far, a total of 86 articles in cooperation with that organization.

McNoldy does a good job explaining what Lunar Nodal Cycle is and how it affects apparent local Relative Sea Level Rise

Bottom Line:

Miami, Florida has high tide flooding because much of Miami Beach (particularly) is built within a foot or two of normal high tides, and some portions are below normal high tides.  So, of course, Miami will experience tidal flooding again at these predicted higher tides.  For Miami’s real Sea Level story, see my earlier essay:  Miami’s Vice.

Oceanic Warming? Well, sorta.

by W. Eschenbach, May 1, 2021 in WUWT

After my last post about the surface warming of the ocean, entitled “How Global Warming Isn’t“, I got to thinking about the warming of the upper part of the ocean. So I got the data for the ocean heat content (OHC) of the top 700 metres of the ocean from the marvelous site, KNMI. If you look under “Monthly Observations” you’ll find a host of most fascinating datasets. Under “Heat Content” on that page, you’ll find the National Oceanic Data Center (NODC) 0-700 metre depth OHC data. And down at the very bottom of that page is a link that will download a 196 megabyte gridded NetCDF file containing the data that I used. (Big file, click at your own risk.)

And what did I find? Well, I’m a visual kind of guy. I mean, I can do the math, but it only makes sense when it comes up as a picture on the silver screen. So here are my graphics. I’m interested in the changes in the oceanic heat content, so these are two views of those trends.

…

…

This is the bottom line. If the world’s creatures, both on land and at sea, were as temperature-sensitive as the alarmists would have us believe, those beings (and we humanoids as well) all would have gone extinct long ago. And near as I can tell, that hasn’t occurred … at least yet.

Gavin’s Falsifiable Science

by W. Eschenbach, Apr 2020 in WUWT

Gavin Schmidt is a computer programmer with the Goddard Institute of Space Sciences (GISS) and a noted climate alarmist. He has a Ph.D. in applied mathematics. He’s put together a twitter threadcontaining what he sees as some important points of the “testable, falsifiable science that supports a human cause of recent trends in global mean temperature”. He says that the slight ongoing rise in temperature is due to the increase in carbon dioxide (CO2) and other so-called “greenhouse gases”. For simplicity, I’ll call this the “CO2 Roolz Temperature” theory of climate. We’ve discussed Dr. Schmidt’s ideas before here on WUWT.

Now, Gavin and I have a bit of history. We first started corresponding by way of a climate mailing list moderated by Timo Hameraanta back around the turn of the century, before Facebook and Twitter.

The interesting part of our interaction was what convinced me that he was a lousy programmer. I asked him about his program, the GISS Global Climate Model. I was interested in how his model made sure that energy was conserved. I asked what happened at the end of each model timestep to verify that energy was neither created nor destroyed.

He said what I knew from my own experience in writing iterative models, that there is always some slight imbalance in energy from the beginning to the end of the timestep. If nothing else, the discrete digital nature of each calculation assures that there with be slight roundoff errors. If these are left uncorrected they can easily accumulate and bring the model down.

He said the way that the GISS model handled that imbalance was to take the excess or the shortage of energy and sprinkle it evenly over the entire planet.

Now, that seemed reasonable for trivial amounts of imbalance coming from digitization. But what if it were larger, and it arose from some problem with their calculations? What then?

So I asked him how large that energy imbalance typically was … and to my astonishment, he said he didn’t know.

Amazed, I asked if he had some computer version of a “Murphy Gauge” on the excess energy. A “Murphy Gauge” (below) is a gauge that allows for Murphy’s Law by letting you set an alarm if the variable goes outside of the expected range … which of course it will, Murphy says so. On the computer, the equivalent would be something in his model that would warn him if the excess or shortage of energy exceeded some set amount.

…
