Flashback: What Michael Crichton Taught Us About Scientific Fraud

by A. Stewart, June17, 2020 in ClimateChangeDispatch


Michael Crichton’s books earned global plaudits.

He invented the genre we now call the techno-thriller whereby it is hard to discern whether it is fact or fiction you were reading.

The reason for that was because he wove his plots around well-researched facts.

One of the best examples is State of Fear.

If you are a student of the climate change furor, it is a must-read, chock full of intelligent insight into the twisted pseudoscience driving the environmental movement.

Below is a key short extract in which Crichton deftly summarizes the reality of nature and man through the character, Kenner. (emphasis added)

 

The graph above demonstrates we are getting better every day in understanding our environment, working with it, and adapting to its harsher realities.

MIT’s Dr. Lindzen Pokes Fun At The ‘Naïve’, Well-Funded ‘Scientific Reasoning’ That 1 Factor – CO2 – Controls Climate

by K. Richard, June 15, 2020 in NoTricksZone


In a new paper, atmospheric physicist Dr. Richard Lindzen summarizes the “implausible” claims today’s proponents of dangerous anthropogenic global warming espouse.

Dr. Richard Lindzen retired several years ago, and yet his immense contribution to the atmospheric sciences lives on. His research is still cited about 600 times per year.

Lindzen recently published another scientific paper (Lindzen, 2020) in The European Physical Journal criticizing the current alarmism in climate science.  Here are a few of the highlights.

1. Doubling the atmospheric CO2 concentration from 280 ppm to 560 ppm results in just a 1-2% perturbation to the Earth’s 240 W/m² energy budget. This doubled-CO2 effect has less than 1/5th of the impact that the net cloud effect has. And yet we are asked to accept the “implausible” claim that change in one variable, CO2, is predominatly responsible for altering global temperatures.

2. A causal role for CO2 “cannot be claimed” for the glacial-to-interglacial warming events because CO2 variations follow rather than lead the temperature changes in paleoclimate records and the 100 ppm total increase over thousands of years produce “about 1 W/m²” of total radiative impact.

3. Climate science didn’t used to be alarmist prior to the late 1980s. Scientists were instead sufficiently skeptical about claims of climatically-induced planetary doom. That changed during the years 1988-1994, when climate research centered on CO2 and global warming received a 15-fold increase in funding in the US alone. Suddenly there was a great financial incentive to propel alarming global warming scenarios.

4. Concepts like “polar amplification” are “imaginary”.

“The change in equator-to-pole temperature difference was attributed to some imaginary ‘polar amplification,’ whereby the equator-pole temperature automatically followed the mean temperature. Although the analogy is hardly exact, this is not so different from assuming that flow in a pipe depends on the mean pressure rather than the pressure gradient.”

Folly: Germany Plans To Convert Coal Power Plant To Burn 100-Year Old Trees In Minutes!

by Die kalte Sonne, June 16, 2020 in NoTricksZone


German Coal Power Plants To Be Converted: To Burn Trees

 

On May 2, 2020, we reported on the movie Burned. In the USA, the focus is on biomass.

However, they do not ferment fast-growing plants into gas as is the case in Europe, rather they cut down trees and burn them in power plants – often together with other things like car tires or soaked railway ties.

The issue is controversial because it is about pure ideology. Climate organisations such as 350.org, which in the USA is like Fridays For Future (FFF) in Europe, have given their blessing to this type of power generation.

The film Planet of the Humans by Michael Moore also denounces this.

Converting CO2 sinks instantly into atmospheric CO2

And so the USA is losing valuable carbon sinks and biotopes, destroying its environment and lying to itself about sustainability and the climate. A tree that takes 50 – 100 years to become big and stately, but then is burned up in a few minutes, can never have a favorable climate balance, no matter how you calculate it. Trees are the new coal, it seems.

But anyone who thinks that this is only done in the USA, where huge forests and thus carbon sinks are destroyed, is mistaken.

“Madness”: German coal plant to be converted to burn trees

The online daily Weserkurier reports on a coal-fired power station in Wilhelmshaven (North Germany) that is to be converted to burn wood. This made Germany’s most famous forester, Peter Wohlleben (book “The Secret Life of Trees“) flash with anger on Twitter.

British Columbia Breaks Cold And Snow Records

by Cap Allon, June 15, 2020 in ClimateChangeDispatch


Record cold and late-spring snow helped drive-home the Grand Solar Minimum message across the BC Interior over the weekend.

According to KelownaNow Meteorologist Wesla English, the Interior –one of the three main regions of the Canadian province of British Columbia– broke a slew of cold records on Saturday.

Kelowna, Kamloops, Clearwater, Penticton, Salmon Arm, and Vernon were among the areas to set new all-time record low-max temperatures for June 13.

“A cool upper low over Southern BC produced chilly temperatures on Saturday, breaking record low daytime highs in several areas,” wrote English.

Below is a breakdown of the records (data courtesy of Environment and Climate Change Canada, and originally reported by kelownanow.com):

  • Kelowna set a new daily record min-high of 12.8C on Saturday, a reading comfortably topping the previous record of 13.3C set in 1981.
  • Kamloops saw its all-time record low smashed, from 1923’s 15C to this weekend’s 13.4C.
  • But it was Salmon Arm that actually saw the biggest change — Saturday’s low-max of 12.4Ccrushed the old record of 14.4C from 1971.
  • Clearwater’s12.8C busted the 13.3C from 1966.
  • While the 13.9C set at Penticton pipped the previous record — 1981’s 14C.

In addition to the cold, this weekend delivered rare late-spring snow to BC, adding to Ontario’s record June snowfall last weekend that brought power outages to parts of the province.

Wet snow accumulated near the summit of the Okanagan Connector between Merritt and Kelowna on Sunday,

Tree Rings & Michael Mann’s Hockey Stick

by P. Homewood, June 14, 2020 in NotalotofPeopleKnowThat


Somehow what starts as a perfectly sensible review morphs into Michael Mann and his discredited hockey stick!

But, as the review itself admits, tree rings tell you more about rainfall than temperature, Indeed, in a much better review in Newsweek, we read how the book reveals in detail the effect that a long period of drought had on the declining Roman Empire in the 4thC.

In fact Mann’s Hockey Stick was hopelessly flawed in many ways. (I would recommend Andrew Montford’s book, “The Hockey Stick Illusion”, for anyone interested.

For a start, the Hockey Stick was based on shonky statistics, which were guaranteed to produce a hockey stick curve regardless of the data fed into it. This was because of the way Mann used Principal Component analysis. In simple terms, Mann’s statistics blew out of all proportion any data which showed a hockey stick effect and ignored all other data.

Secondly, as far as tree rings were concerned, it was heavily dependent on bristlecone pines. It has long been known that the marked increase in bristlecone growth in the 19th and 20thC is due to CO2 fertilization, not temperature. When bristlecones are taken out of Mann’s analysis. the hockey stick disappears.

Thirdly, when tree ring and other proxy data diverged from rising temperature data in the late 20thC, Mann ignored the proxies and spliced the temperature data onto his graph.

There are also a whole host of other major flaws in the Hockey Stick, not related to tree rings.

Study: As Sea Levels Rise, Island ‘Drowning’ Is Not Inevitable

by A. Williams, June12, 2020 in ClimateChangeDispatch


Coral reef islands across the world could naturally adapt to survive the impact of rising sea levels, according to new research.

The increased flooding caused by the changing global climate has been predicted to render such communities – where sandy or gravel islands sit on top of coral reef platforms – uninhabitable within decades.

However, an international study led by the University of Plymouth (UK) suggests that perceived fate is far from a foregone conclusion.

The research, published in Science Advances, for the first time uses numerical modeling of island morphology alongside physical model experiments to simulate how reef islands – which provide the only habitable land in atoll nations – can respond when sea levels rise.

THE CHANGING JET STREAM AND GLOBAL COOLING

by Cap Allon, June12, 2020 in Electroverse


Studying the JET STREAM has long been an indicator of the weather to come. And to study the jet stream attention must turn to the SUN.

When solar activity is HIGH the jet stream is tight, stable, and follows somewhat of a straight path. But when solar activity is LOW that meandering band of air flowing some 6 miles above our heads becomes weak and wavy, it effectively buckles, which has the effect of diverting frigid Polar air to atypically low latitudes and replaces it with warmer tropical air masses.

The jet stream reverts from a Zonal Flow to a Meridional Flow — and, depending on which side of the jet stream you’re on, you’re either in for a spell of unseasonably cold or hot weather, and/or a period of unusually dry or wet conditions.

 

Observations historiques d’inondations jusqu’à la fin du 19ème siècle (première partie)

by IRM, 2020


Nos observations historiques d’inondations font l’objet de trois articles. Voici le premier qui traite des inondations jusqu’à la fin du 19ème siècle.

En août 2019, nous avons introduit la possibilité d’envoyer vos propres observations via notre application météo. Cette nouvelle fonctionnalité semble avoir plu aux utilisateurs de notre app, puisque nous avons reçu près de 600.000 observations jusqu’à présent ! Etant donné ce succès, nous avons décidé en avril 2020 d’y ajouter deux nouveaux types d’observations à rapporter : les inondations et les phénomènes optiques. Ces phénomènes ont été observés de tous temps, c’est pourquoi nous avons décidé de nous plonger dans plus d’un millénaire d’anciennes observations de halos et d’arcs-en-ciel. Dans ce nouvel article, vous trouverez quelques observations d’inondations telles qu’elles ont été perçues et décrites dans d’anciens manuscrits, livres et journaux publiés en Europe de l’Ouest jusqu’au 19ème siècle.

ASTONISHING, RECORD-BREAKING GAINS CONTINUE ACROSS THE GREENLAND ICE SHEET — MSM SILENT

by Cap Allon, June 11, 2020 in Electroverse


The month of June is breaking records across the Greenland ice sheet, and not records for warmth and melt –as the mainstream media have trained you to expect– but new benchmarks for COLD and GAINS.

The SMB gains occurring right now across Greenland are truly astonishing.

Data-driven FACTS reveal vast regions to the south have been GAINING RECORD/NEAR-RECORD LEVELS of snow & ice all month.

Never before in June has the Greenland ice sheet grown by more than 4 Gigatons in a single day (since 1981 when DMI records began), but now the past week has gone and delivered two such days — June 3, and now yesterday, June 10.

In fact, yesterday’s gains actually neared 5 Gts — you can see from the chart below how anomalous that gain is for the time of year:

 

Blue line (Gt/day): total daily contribution to the SMB from the entire ice sheet. Grey line: mean value from 1981-2010 (DMI).

DWD Reverses: Admits Data From Germany’s Infamous Ultra-Hot Lingen Weather Station Need To Be Rechecked

by P. Gosselin, June10, 2020 in NoTricksZone


Recently I wrote here how Germany’s now infamous record-setting weather station in Lingen was producing readings that were 2-3°C hotter than surrounding stations, yet the German DWD weather service refused to acknowledge the station was likely producing bad data. Today they admit the station has problems and that they will be moving it to a better location.

Last year’s all-time record high is now in question.

Lingen’s heated readings

Last summer the Lingen station, located in northwest Germany near the Dutch border, smashed the country’s all-time record high when the ‘mercury’ rose to a scorching 42.6°C during a late July heat wave. The previous all-time high for Germany was a comparatively cool 40.3°C.

 

Lingen’s readings of late July 2019 compared to other stations in the surrounding region (July 23 – July 27).

Decadal predictability of North Atlantic blocking and the NAO

by Athanasiadis et al., June 3, 2020 in Nature (Open Access)


Abstract

Can multi-annual variations in the frequency of North Atlantic atmospheric blocking and mid-latitude circulation regimes be skilfully predicted? Recent advances in seasonal forecasting have shown that mid-latitude climate variability does exhibit significant predictability. However, atmospheric predictability has generally been found to be quite limited on multi-annual timescales. New decadal prediction experiments from NCAR are found to exhibit remarkable skill in reproducing the observed multi-annual variations of wintertime blocking frequency over the North Atlantic and of the North Atlantic Oscillation (NAO) itself. This is partly due to the large ensemble size that allows the predictable component of the atmospheric variability to emerge from the background chaotic component. The predictable atmospheric anomalies represent a forced response to oceanic low-frequency variability that strongly resembles the Atlantic Multi-decadal Variability (AMV), correctly reproduced in the decadal hindcasts thanks to realistic ocean initialization and ocean dynamics. The occurrence of blocking in certain areas of the Euro-Atlantic domain determines the concurrent circulation regime and the phase of known teleconnections, such as the NAO, consequently affecting the stormtrack and the frequency and intensity of extreme weather events. Therefore, skilfully predicting the decadal fluctuations of blocking frequency and the NAO may be used in statistical predictions of near-term climate anomalies, and it provides a strong indication that impactful climate anomalies may also be predictable with improved dynamical models.

Weather Extremes? Are they caused by global warming?

by Ralph Alexander, June 4, 2020 in CO2Colation


Critical Review Confirms IPCC Assessment On Extreme Weather: “No sign that extreme weather events are getting worse”

The paper, by physicist Dr Ralph Alexander, looks at trends in hot and cold weather extremes, floods and droughts, hurricanes and wildfires and finds only a minor increase in cold weather extremes.

According to Dr Alexander, weather extremes is one area where the IPCC has been reasonably empirical and scientific in recent years.

As he explains:

The IPCC stands out, among those who believe that global warming is primarily due to human activity, as a voice of restraint on the issue of extreme weather. My review is in broad agreement with their position: there is little sign things are getting worse.”

In particular, Dr Alexander points to the underreported global reductions in floods, wildfires and hurricanes, but he cautions that many of the changes are likely to be cyclical.

The key driver for many weather extremes is natural ocean cycles like El Nino and the Atlantic Multidecadal Oscillation. Eventually these cycles will turn, and we should be ready. But we shouldn’t be under any illusion that we can prevent extreme weather by changing our lifestyles”.

COVID-19 Global Economic Downturn not Affecting CO2 Rise: May 2020 Update

by Roy Spencer, June 5, 2020 in GlobalWarming


The Mauna Loa atmospheric CO2 concentration data continue to show no reduction in the rate of rise due to the recent global economic slowdown. This demonstrates how difficult it is to reduce global CO2 emissions without causing a major disruption to the global economy and exacerbation of poverty.

After removal of the strong seasonal cycle in Mauna Loa CO2 data, and a first order estimate of the CO2 influence of El Nino and La Nina activity (ENSO), the May 2020 update shows no indication of a reduction in the rate of rise in the last few months, when the reduction in economic activity should have shown up.

I had previously explained why the slowdown would likely not be large enough to affect measured atmospheric CO2 levels compared to natural variations in global sources and sinks of CO2. I calculated that the Energy Information Administration-estimated 11% reductions in CO2 emissions during 2020 would have to be four times larger to stop the rise of atmospheric CO2 over 2019 values (assuming no substantial natural variations in CO2 sources and sinks).

BBC’s Fake Claim About “Hottest May”

by P. Homewood, June 5, 2020 in NotaLotofPeopleKnowThat


I make no comment about the global numbers, but would simply point out that none of the official agencies have released their data for May. The BBC claim comes from Copernicus, the EU agency, not regarded as a reliable source.

However the BBC claim about the UK is hopelessly wide of the mark. According to the Met Office, last month was only the 15th warmest May since 1884, and was not even as warm as 1893 and 1911!

https://www.metoffice.gov.uk/research/climate/maps-and-data/uk-temperature-rainfall-and-sunshine-time-series

Such sloppy reporting is only too common at the BBC, and not just where climate change is concerned. It only takes a minute to find the Met Office data, and I find it hard to understand why the programme editors did not think it worthwhile checking such an outlandish claim first.

Needless to say, I have filed a complaint, to add to the list of BBC climate lies!!

 

Models Can’t Accurately Predict Next Week’s Weather, So Why Should We Trust Them To Predict Climate Change?

by D. Turner, June 2, 2020 in WUWT


It’s curious … SpaceX has all the money in the world, and they didn’t hire someone who could have accurately predicted the afternoon weather in Florida on May 27, 2020.  Seems like a huge oversight, doesn’t it?  And to think there are scores of nonprofit leaders and academics in Washington, DC who can accurately predict global temperatures 10, 15, even 50 years into the future.

Oh, stop it with the “climate isn’t weather” rebuttal. It’s trite and silly. The guys who says “food isn’t cuisine” is a food critic, and by default, haughty and obnoxious.

How about this one: science isn’t semantics.

Sunny May–But Only The 48th Warmest

by P. Homewood, June 3, 2020 in NotaLotofPeopleKnowThat


While we’re on with Harrabin’s hysterics about May’s sunny weather being due to climate change, it is appropriate to point out to him that last month was far from being the hottest on record in England:

https://www.metoffice.gov.uk/hadobs/hadcet/data/download.html

 

In fact there have been 47 hotter Mays since 1659. The hottest was 1833, and the five hottest were all pre 1850.

Quarantines, Lockdowns Had No Impact On Global CO2 Levels

by Climate at a Glance, June 1, 2020 in ClimateChangeDispatch


The COVID-19, aka Coronavirus pandemic, is causing a worldwide shutdown in economic activity as businesses close, airlines cancel flights, energy production is reduced, and people shelter in their homes and drive less.

Climate activists expected this economic downtown to translate to less energy usage, and therefore less CO2 emissions globally.

While that has indeed happened, with China seeing a 40% emissions drop, and an expected 11% reduction in energy-related CO2 emissions in the U.S. this year, it didn’t translate into the proof they were seeking.

What scientists are looking for is any evidence of a decline in global atmospheric CO2 concentrations that would be strong enough to attribute to the economic downturn.

University of Alabama climate scientist Dr. Roy Spencer used a simple method1 for removing the large seasonal CO2 cycle2, due to plant photosynthesis increases/decreases with seasons, from the Mauna Loa CO2 data, and well as the average effects from El Nino and La Nina events, which change the rate of ocean outgassing of CO2.

The result: no obvious downtown in global CO2 levels has been observed3,4.

As can be seen in Figure 1, the latest CO2 data show no downtrend, but instead just a ripple, that is not unlike other ripples in the graph when there was no crisis and resulting economic downturn.

Cook’s 97% Scam Debunked

by P. Homewood, October 29, 2020 in NotaLotofPeopleKonwThat


Yesterday, we saw how easily debunked the original “97% of scientists agree” turned out to be.

There therefore had to be a renewed attempt by the warmist establishment to make the claim stick, so step forward John Cook with a much more sophisticated scam.

Jose Duarte, expert in Social Psychology, Scientific Validity, and Research Methods, has actually called the Cook paper “multiply fraudulent”, and, as far as I know, Cook has taken no action to challenge the claim. This, as much as anything else, shows just what a con trick the whole business was. How many scientists, after all, would accept being called fraudulent without taking action?

WASHINGTON, D.C. JUST SUFFERED ITS COLDEST MAY SINCE 2005

by Cap Allon, June 2, 2020 in Electroverse


Like April, May was cooler than average across the District,” admits filthy warm-mongers the washingtonpost.com in a recent article. The month officially logged an average temperature of just 63.8F, which is 2.2F below the 30-year average, and made for Washington’s coldest May in 15 years.

The average temperature more closely matched a typical May in New York City, points out the Southeast Regional Climate Center. And with NYC located some 200 miles north of Washington, May 2020 serves as a great illustration of how the GSM is driving the COLD LINE south.

The past two months also marked the first time since 2003 that both April and May were colder than average across the District.

In addition, May 9’s daily high of 52F was the lowest-high during the month of May since May 12, 2008 (solar minimum of cycle 23), and the chill even brought a few snow flurries to Washington’s far north and west suburbs. That 52F on May 9 also matched the record lowest-high for the date which was set way back in 1877 (solar minimum of cycle 11).

Many more all-time cold-records fell across the District that day; including Dulles smashing its record for min-high from 1977 (solar minimum of cycle 20), and Baltimore toppling both its all-time min-low from 1966 (solar minimum of cycle 19) as well as its min-high set back in 1977 (solar min of cycle 20)and 1947 (solar min of cycle 17).

Destroying the environment to save it

by Ch. Rotter, May 31, 2020 in WUWT


Pseudo-green energy will wreak devastation, pretending to prevent exaggerated climate harm

Paul Driessen

“We had to destroy the village in order to save it.” The infamous Vietnam era quotation may or may not have been uttered by an anonymous US Army major. It may have been misquoted, revised, apocryphal or invented. But it quickly morphed into an anti-war mantra that reflected attitudes of the time.

For Virginians and others forced to travel the path of “clean, green, renewable, sustainable” energy, it will redound in modern politics as “We had to destroy the environment in order to save it.”

Weeks after Governor Ralph Northam signed Virginia’s “Clean Economy Act,” which had been rushed through a partisan Democrat legislature, Dominion Energy Virginia announced it would reach “net zero” greenhouse gas emissions by 2050. To do so, the utility company will raise family, business, hospital and school electricity bills by 3% every year for the next ten years – as these customers and state and local governments struggle to climb out of the financial holes created by the ongoing Coronavirus lockdown.

Just as bad, renewable energy mandates and commitments from the new law and Dominion’s “integrated resource plan” will have major adverse impacts on Virginia and world environmental values. In reality, Virginia’s new “clean” economy exists only in fantasy land – and only if we ignore “clean” energy CO2 emissions, air and water pollution, and other environmental degradation around the world.

Dominion Energy plans to expand the state’s offshore wind, onshore solar and battery storage capacity by some 24,000 megawatts of new “renewable” energy by 2035, and far more after that. It will retain just 9,700 MW of existing natural gas generation, and only through 2045, build no new gas-fired units, and retire 6,200 megawatts of coal-fired generation. This will reduce in-state carbon dioxide emissions, but certainly won’t do so globally. The company intends to keep its four existing nuclear units operating.

To “replace” some of its abundant, reliable, affordable fossil fuel electricity, Dominion intends to build at least 31,400 megawatts of expensive, unreliable solar capacity by 2045. The company estimates that will require a land area some 25% larger than 250,000-acre Fairfax County, west of Washington, DC. That means Dominion Energy’s new solar facilities will blanket 490 square miles (313,000 acres) of beautiful croplands, scenic areas and habitats that now teem with wildlife.

Arctique géologique, part 2

4/ Les cycles glaciaires  arctiques (Pliocène/Pléistocène)

4.1. Introduction : le forçage orbital et l’englaciation

Le climat de la Terre est géré à un premier niveau par l’apport énergétique lié à l’apport solaire, en fonction de l’évolution cyclique de la forme de l’orbite de notre planète autour du soleil. Ce forçage s’appelle forçage orbital et a toujours existé depuis que notre système planétaire existe.  Ce forçage présente une cyclicité parfaitement calculable en fonction des interactions par attraction entre les différentes planètes du système solaire et le soleil. Elle varie relativement peu au cours du temps. Par contre, l’orbite terrestre est une ellipse dont l’élongation varie au cours du temps, nous éloignant ou nous rapprochant du soleil, c’est ce que nous appelons l’excentricité.  De plus, l’axe de rotation de la Terre n’est pas vertical sur le plan orbital ou d’écliptique et oscille également, permettant un déficit en énergie reçue au niveau des pôles, géré par son obliquité. Enfin la Terre ne parcourt pas son orbite en exactement un an : les saisons pourront être en avance ou en retard sur l’orbite par rapport au minimum ou au maximum d’insolation : ceci s’appelle la précession des équinoxes.

L’englaciation Cénozoïque débute en position polaire sous contrôle de la tectonique des plaques, de l’évolution des océans, de la circulation océanique et des reliefs orogéniques disponibles pour stocker de la glace. Elle apparaît donc en premier sur l’Antarctique puis au Néogène, sur l’Arctique Canadien en période de faible obliquité. Ensuite, elle descendra en latitude au fur et à mesure de l’évolution de l’ère glaciaire.

Fig. 24 : LGM ou Last Glacial Maximum, c’est-à-dire la glaciation du ‘Dernier Glaciaire’ dans l’hémisphère nord avec des plateformes de glaces débordant sur l’océan Arctique recouvert de banquise (image CLIMAP). La glace qui recouvrait une grande partie de l’Amérique du Nord, du nord de l’Europe et une partie de l’Asie était épaisse de 3 à 4 km et le niveau marin plus bas de 120 m par rapport à l’Actuel, ce qui permit des passages terrestres, inexistants aujourd’hui suite à la remontée du niveau marin lors de la déglaciation. Cette situation est aussi à l’origine d’une aridification intense (non discutée dans cet article). Les glaces se mirent en place vers 33 ka et leur extension maximale est comprise entre 26,5 ka et 20-19 ka (Clark et al. 2009).

 

THE SUN UNLEASHES STRONGEST SOLAR FLARE IN 3 YEARS — GSM + MAGNETIC EXCURSION = BYE-BYE EMPIRE MODEL

by Cap Allon, May 30, 2020 in Electroverse


Earth’s magnetosphere continues to weaken (due to an intensifying GSM AND a magnetic excursion/reversal), but at the same time the Sun’s next cycle (25) is showing signs of stirring– this combo spells bad news for all those reliant on the electrical grid, and could deliver a civilization-resetting one-two knockout.

Yesterday (May 29), in the pits of the deepest Solar Minimum of the past 100+ years, the sun unleashed a flurry of spectacular solar flares:
