“The atmospheric warmth transport on Earth from the Equator to the poles is basically carried out by the mid-latitude storms. Nevertheless, there isn’t a passable concept to explain this elementary function of the Earth’s local weather.”
(Barry, Craig, & Thuburn, 2002)
That is the transcript of the discuss I gave in Tom Nelson’s podcast interview right here.
After Leon Barry and his colleagues write the above assertion of their Nature article, they write that the center latitudes are a zone of robust temperature gradients and these gradients generate storms that may be extreme. Their paper proposes that the severity of the storms is proportional to the temperature gradient, such that the smaller the temperature gradient from the tropics to the poles, the less extreme storms are wanted to perform the duty of transferring extra tropical power (or warmth) to the poles. Preserve this idea in thoughts as I describe meridional (north-south) power transport.
A lot of this discuss relies on Javier Vinós’ new e book Local weather of the Previous, Current, and Future, A Scientific Debate, 2nd Version, Chapter 10. Determine 1, from the e book, exhibits the worldwide common temperature over one common 12 months.
Whole photo voltaic irradiance (known as TSI in Determine 1) constitutes over 99.9% of the power enter into the local weather system. The power acquired from the solar adjustments all year long by 6.9% as a result of always altering Earth-Solar distance. The Earth is closest to the solar (perihelion) across the 4th of January and farthest (aphelion) across the 4th of July. Though half the Earth is illuminated by the solar at any given time, the adjustments within the orientation of Earth’s axis, the irregular distribution of land lots, adjustments in albedo (or reflectivity), and regional adjustments in floor and atmospheric temperature, trigger necessary seasonal adjustments within the quantity of mirrored photo voltaic radiation (known as “RSR” in Determine 1) and outgoing longwave radiation (or “OLR”). Because of this, the temperature of the Earth is at all times altering, and the planet isn’t in thermal equilibrium.
Opposite to what we’d anticipate, the Earth is warmest simply after the June solstice, when it’s farthest from the solar, and coldest simply after the December solstice, when it’s receiving 6.9% extra power from the solar. Earth’s common floor temperature is about 14.5°C, which is chilly by geological requirements, however throughout the 12 months it warms and cools by 3.8°C, as proven in Determine 1. As anticipated, Earth emits extra power (known as TOR, the purple dotted line in Determine 1) when it’s cooling and fewer when it’s warming, no matter what it’s receiving on the time. The concept of an power steadiness on the prime of the ambiance is clearly improper. The Earth shows little or no temperature variability from 12 months to 12 months, however there isn’t a purpose to suppose we correctly perceive the mechanisms concerned in Earth’s temperature stability. And, actually, the concept two-degrees of worldwide warming is harmful is absurd.
In Determine 1 the worldwide floor common temperature of the planet (the thick black line in Determine 1) adjustments a lot principally as a result of the Northern Hemisphere (the skinny stable black line) varies by 12°C within the common 12 months. The planet has two peaks of power loss to area (or TOR in Determine 1), these are when every pole is darkish and cools. The best is when the North Pole is darkish. Between November and January, the planet emits extra power than at some other time. The Southern Hemisphere is the dashed black line. The 1961–1990 temperature information are from Phil Jones on the Hadley Climatic Analysis Middle. The radiation information are from Barbara Carlson and colleagues.
Determine 1 exhibits that though the local weather system is fully powered by photo voltaic irradiance, what determines Earth’s temperature is what the local weather system does with that power. But, the local weather system is extraordinarily advanced. As Leon Barry and colleagues say within the quote at first of this discuss, trendy climatology lacks a correct concept of how power strikes inside our planet’s local weather system. It’s potential to mannequin what just isn’t correctly understood, however to consider such a mannequin is silly. Determine 2 exhibits Earth’s fundamental power redistribution processes.
The typical absolute (or Kelvin) temperature of the floor doesn’t range that a lot with latitude, it lies between 278 and 300 Kelvin between 60°N–60°S. The quantity of radiation that Earth’s floor emits is a perform of this absolute temperature, the quantity that reaches outer area is generally a perform of greenhouse gasoline focus and cloud cowl, each of that are increased within the tropics, the place the upper absolute floor temperatures are. Thus, outgoing longwave radiation doesn’t range that a lot with latitude. The result’s that the web radiation flux on the prime of the ambiance (TOA) is optimistic (extra incoming than outgoing) on the annual common between about 30°N-30°S and damaging between about 30° North or South and the poles, as proven in Determine 2. Clearly, the exact level the place the web incoming radiation equals the outgoing varies with the hemisphere, the month of the 12 months, different orbital parameters, and cloudiness, however the common location is close to 30° North or South. The cooling, as one strikes poleward from the tropics, is generally from lowered insolation—the quantity of photo voltaic power reaching the floor. The discount in insolation poleward creates a web power deficit and a latitudinal temperature gradient. Vitality is transported from latitudes the place there’s a web acquire of power (the purple space) to latitudes the place there’s web lack of power to outer area (the blue space), by meridional transport.
Meridional transport strikes much more power in direction of the winter pole. The winter pole radiates way more power to area than it receives, for the reason that solar is beneath the horizon. Just about all power the winter pole emits is transported there by way of winter storms or is latent warmth launched as summer season meltwater freezes.
With out meridional transport, the temperature of the blue areas—the place the web stream of power is towards outer area, that’s damaging, would lower constantly till outgoing longwave radiation emissions are sufficiently low to match insolation. At the hours of darkness polar evening, that temperature would strategy absolute zero or –273°C. Meridional transport of air, water vapor, and water within the ambiance and oceans retains the temperature of the darkish pole a lot hotter than that.
The Earth’s floor latitudinal temperature gradient is a direct consequence of the latitudinal insolation gradient. Thermal power flows from hotter areas to colder areas. That is the bodily foundation of meridional transport, however the local weather system is advanced, so it’s removed from a passive course of that relies upon solely on the temperature distinction between the tropics and the poles. As a substitute, it’s a advanced course of, that relies upon upon each geography and local weather processes. It’s potential to drive extra power with a smaller temperature distinction than with a bigger temperature distinction. For instance, meridional transport has elevated within the first twenty years of the 21st century, regardless of Arctic warming, which has lowered the latitudinal temperature gradient. It isn’t so simple as Leon Barry and colleagues write of their article, however a lot of what he wrote is right.
We all know that Earth’s latitudinal temperature gradient has diverse loads over the geological previous. Wladimir Köppen, a Russian-German scientist, studied the sun-climate impact within the 19th century and established a local weather classification system that’s nonetheless used at present. His local weather zones are outlined by way of temperature, precipitation, and their seasonal distribution. Many teams of crops and animals are restricted to a slender vary of temperatures; and so are sure geological processes. Utilizing this info, together with well-dated fossils and rock formations from around the globe, Christopher Scotese has mapped previous local weather historical past, as a part of his Paleomap Venture. The data allowed him to map the worldwide Köppen local weather zones each 5 million years, for the reason that starting of the Phanerozoic 540 million years in the past. Maps of the Köppen belts as they exist at present and 52 million years in the past are proven in Determine 3.
Every Köppen belt mixture defines a latitudinal temperature gradient. This permits Scotese and his colleagues to create the temperature graphs proven within the right-hand illustration. The graphs can be utilized to estimate an approximate world common floor temperature for the interval. Thus, Scotese and his colleagues have proven that the latitudinal temperature gradient is a elementary local weather variable, an thought that’s in keeping with the quote from Barry, et al. at the start of this discuss. Utilizing Scotese’s definitions, the current (21st century) latitudinal temperature gradient is taken into account a “extreme icehouse,” as proven in Determine 3. Within the right-hand graph, we examine the present extreme icehouse temperature gradient in blue, with the Early Eocene hothouse gradient from 52 million years in the past. Discover that at present, Greenland and Antarctica are coated in ice, proven in blue on the decrease map and the poles are ice free within the higher map. An icehouse local weather is characterised by year-round ice sheets on the poles.
The local weather throughout the Early Eocene hothouse was fairly heat by at present’s requirements. The typical world floor temperature reached 10°C hotter than at present. The so-called “burst of mammalian first appearances” occurred at the moment. One of many mammals that first appeared throughout the Early Eocene was the first primate, our distant ancestor. Primates rapidly unfold around the globe. Apart from new mammals, many new genera of turtles, lizards, and crops advanced and thrived throughout this time. Some deep-water foraminifera went extinct, however most organisms did properly and dispersed broadly.
The existence of very totally different previous climates on Earth creates an insurmountable downside for contemporary “consensus” climatology. Over the past glacial most, 20,000 years in the past, the power acquired from the solar was the identical as now. Not solely that, however the Milankovitch orbital parameters have been additionally almost the identical. The distribution of photo voltaic power over the Earth was almost similar to now, but the local weather was very totally different. Vitality enter to the local weather system should have been decrease as a result of the bigger ice sheets mirrored extra photo voltaic power and the greenhouse impact was decrease. The decrease greenhouse impact was resulting from much less atmospheric CO2 and out there water. Decrease temperatures made CO2 extra soluble within the oceans, eradicating it from the air. The very giant continental ice sheets within the final glacial most eliminated quite a lot of water and water vapor and saved it in ice, eradicating it from the local weather system.
A decrease power enter and a bigger latitudinal temperature gradient should have drained the tropics of warmth by way of stronger meridional transport, however that was not the case. There may be nonetheless controversy about tropical temperatures over the past glacial most, however it seems that they have been solely 1–2°C colder than current. That is in keeping with proof offered by Chris Scotese and colleagues that tropical temperatures haven’t modified a lot over the course of the previous 540 million years regardless of large adjustments within the common temperature of the planet (9–30°C). You’ll discover in Determine 3 that the very heat Early Eocene hothouse local weather has an identical temperature on the equator to the current day, however the distinction on the South Pole is 44°C and it’s 23°C on the North Pole. Clearly, a lot of the warming happens within the increased latitudes.
If the final glacial most creates an issue for the way meridional transport operates throughout a glacial interval, the equable local weather of the Early Eocene leads to a paradox that trendy consensus climatology can’t clear up. At present the Earth is in a extreme icehouse local weather with a really steep latitudinal temperature gradient because the right-hand graph in Determine 3 makes very clear. At present, temperature falls by 0.6–1°C/°latitude from the equator to the winter pole. Such a chilly surroundings has been comparatively uncommon throughout the previous 540 million years, present lower than 10% of the time. The Early Eocene Earth had a median temperature estimated at 24 to 25°C, that Scotese describes as hothouse circumstances. The Early Eocene latitudinal temperature gradient was very shallow, at 0.25–0.45°C/°latitude, with temperatures on the North Pole above freezing all 12 months spherical, as attested to by the presence of frost-intolerant biota. These hothouse circumstances have been even rarer. Over 60% of the Phanerozoic Eon the Earth had a median temperature of 19–20°C. The typical world floor temperature of your complete Phanerozoic—the previous 540 million years—is a really nice 18°C, about 3.5°C hotter than at present.
The local weather of the Early Eocene is outlined as equable. It’s characterised by a heat world with a low latitudinal temperature gradient, low seasonality, and fewer mid- and high-latitude storms than at present. The failure of recent consensus local weather concept to clarify these durations has been termed the “equable local weather downside.” To breed the Early Eocene heat continental inside temperatures and above freezing winter polar areas, fashions should elevate CO2 ranges to 4700 ppm, use an implausible local weather sensitivity to CO2, and permit tropical temperatures to exceed 35°C. Nevertheless, the perfect CO2 estimates for the Early Eocene climatic optimum place possible CO2 ranges at 500–1,000 ppm, and the best estimates are lower than 2,000. Additional, it’s unlikely that tropical temperatures above 30°C are potential, as a result of effectivity of warmth elimination by means of evaporation and deep convection (the convection of moist air to the higher troposphere) at that temperature. Additionally, mammals can’t survive above a wet-bulb temperature of 35°C, the place they grow to be unable to lose warmth. But, fossils present us that mammals thrived within the Early Eocene. The best wet-bulb temperature on Earth at present is 30°C, and there’s no purpose to suppose it has been increased at any time prior to now at locations the place mammal fossils are discovered.
The equable local weather downside is intimately associated to the “low gradient downside.” Conceptually, we consider that to have heat poles extra warmth have to be transported there, particularly in winter, to compensate for the insolation deficit. Warmth meridional transport is a vital a part of the planetary power finances, and with out it the poles could be a lot colder. However meridional transport relies on the latitudinal temperature gradient since a lot of the poleward transport within the current local weather is thru mid- to high-latitude storms ensuing from atmospheric instability resulting from steep temperature gradients. The paradox arises as a result of, whereas the nice and cozy poles of the Early Eocene appear to demand extra power transport, the lowered latitudinal temperature gradient implies lowered meridional transport. It’s no marvel that local weather fashions wrestle with this conundrum.
The decrease ambiance is a skinny movie of gasoline, simply 1/600 of the Earth diameter (or about 10 km). This skinny ambiance has the essential position of at all times sustaining a land floor temperature appropriate with advanced life, one thing it has accomplished for at the very least the previous 540 million years. To do this it should compensate for floor temperature variations arising from variations in insolation. First, it should compensate for the distinction between day and evening. It does so primarily by means of the greenhouse impact and clouds, each cut back cooling at evening by delaying radiation emissions to area, and clouds replicate incoming photo voltaic radiation throughout the day. Then, it should compensate for the latitudinal lower in insolation and its seasonal adjustments as a result of axial tilt of the planet. It does this by means of meridional warmth transport.
The three components accountable for Earth’s thermal stability then are the greenhouse impact, clouds, and meridional transport. Trendy climatology ignores the final two and focuses solely on the primary, by creating the CO2 “management knob” local weather speculation. The impact of clouds and their variability on local weather change remains to be largely unknown. In accordance the IPCC AR6 report (on web page 979) cloud suggestions to floor warming might be optimistic or damaging and it’s the largest supply of uncertainty within the impact of greenhouse gases on the local weather.
As you may see in Determine 4, power is barely exchanged between the local weather system and outer area by means of the highest of the ambiance. Because of this meridional transport has a web zero worth when built-in over the entire planet, since transferring power round doesn’t alter the entire power throughout the system. This reality has brought about many local weather scientists to consider that adjustments in meridional transport can’t trigger local weather change, in all probability probably the most elementary mistake of recent consensus climatology.
The ambiance can transfer a large amount of power, rapidly and effectively, over your complete floor of the Earth. Most meridional transport is carried out primarily by the ambiance. Solely within the deep tropics (10°S–10°N) is the ambiance insufficient for the mandatory power transport. That is the area the place most photo voltaic power enters the local weather system. On this area the ocean should perform a lot of the warmth transport within the deep tropics. As a result of the tropical Pacific Ocean is so giant—it goes virtually half-way across the planet—the El Niño/Southern Oscillation or ENSO manages to maintain the tropical warmth content material below management. El Niño is the way in which the Earth periodically expels extra amassed warmth that standard meridional transport processes didn’t carry away. ENSO is an important a part of the worldwide meridional transport system.
Poleward of 10-20° latitude, the ocean transfers most of its power to the ambiance, significantly within the western ocean basin boundary currents, just like the Kuroshio Present within the Pacific and the Gulf Stream within the Atlantic. As soon as the sea-ice edge is reached, the transport is basically carried out solely by the ambiance, for the reason that power flux by means of the ocean ice is way lower than from the liquid ocean floor. The first mechanism of warmth switch is evaporation, so sea-surface temperature just isn’t as necessary for ocean-atmosphere power stream as wind pace and air moisture, since these are the principal components governing evaporation. Nevertheless, evaporation limits the utmost sea-surface temperature to about 30°C.
When west-east winds are dominant within the mid- to high-latitudes, meridional or south-north winds, and meridional transport of power decreases, which causes world warming. When west-east (or zonal) winds lower, meridional transport will increase, extra power reaches the pole, and the planet cools.
Angular momentum is exchanged between the stable Earth–ocean and the ambiance resulting from adjustments in wind course and pace within the increased latitudes. The adjustments in angular momentum change the Earth’s rotation pace, which we measure because the size of day. The size of day will increase, inflicting a shorter day, when common zonal (west to east) wind speeds enhance. When zonal wind pace will increase, the polar vortex turns into stronger, chilly air is trapped within the Arctic, and the planet warms.
Zonal wind circulation is stronger in winter, when extra angular momentum resides within the ambiance resulting from a deeper latitudinal temperature gradient, so the Earth rotates sooner in January and July, and slower in April and October, when zonal circulation is weaker. The fundamental 11-year photo voltaic cycle (the Schwabe Cycle) and the ENSO cycle are recognized to have an effect on zonal versus meridional winds and thus the pace of Earth’s rotation.
However whereas the position of ENSO is broadly recognized and reported, the position of the solar stays largely ignored. Now we have discovered that the solar impacts local weather by means of its impact on atmospheric circulation, not by means of variations in whole photo voltaic irradiance.
Transport of power by the ambiance is linked to the transport of mass, momentum, moisture, and clouds. It principally takes place within the troposphere. North and south of about 30° latitude power is generally transported by means of storms in most well-liked routes over ocean basins. The 2 most vital Northern Hemisphere storm tracks are proven in Determine 5 in purple.
Determine 6 exhibits the correlation between photo voltaic exercise (proven in purple) and common atmospheric angular momentum. The 2 correlate properly and positively from 1920 till at present, however they anticorrelate (damaging correlation coefficient) previous to 1920. Many photo voltaic/local weather correlations reversed round 1920, inflicting a lot confusion amongst photo voltaic/local weather scientists. Previous to 1920, a low sunspot quantity was thought to trigger hotter climate, a damaging correlation. After 1920 this relationship reversed, and sunspots correlated positively with warming.
After the 1920 reversal, the concept there was a connection between the Solar and local weather was discredited. The explanation for the reversal is unknown and can possible stay so till it occurs once more. Douglas Hoyt and Kenneth Schatten clarify that the reversals seem to occur each 80-120 years, such that 1600 to 1720 produced a damaging correlation, 1720 to 1800 a optimistic correlation, 1800 to 1920 a damaging correlation, and 1920 to the current a optimistic correlation. We’d see one other reversal throughout the subsequent few many years, which could enable a mechanism to be found.
Realizing how warmth is transported into the Arctic permits us to look at the phenomenon of Arctic amplification, that’s the concept when world temperatures rise, they rise sooner within the Arctic and Antarctic. Basic circulation fashions have predicted this for the reason that first fashions have been written by Syukuro Manabe and Kirk Bryan within the Nineteen Sixties. Nevertheless, within the trendy world warming interval Antarctic amplification has not been noticed. Via 1995 so little Arctic amplification was noticed, regardless of intense world warming the earlier 20 years, that Judith Curry stated:
“The relative lack of noticed warming and comparatively small ice retreat might point out that GCMs are overemphasizing the sensitivity of local weather to high-latitude processes.”
Curry, et al., 1996
That was about to vary that 12 months when Arctic amplification all of the sudden accelerated, as proven in Determine 7. However the query remains to be legitimate. Why was Arctic amplification small earlier than 1996, when intense world warming was going down, and enormous after 1996 when the worldwide warming charge decreased—the so-called “Pause?” Trendy climatology doesn’t have a solution for that.
In Determine 7, the black curve is the summer season (June–August) imply temperature anomaly from the European Climate Middle reanalysis database for the area north of 80°N. The purple curve is the corresponding winter (December–February) imply temperature anomaly for a similar area.
The Arctic in winter constitutes the largest heat-sink—web lack of power to area—on the planet. Arctic precipitable water is about 1.5 cm in summer season, however in winter it drops to virtually zero. Because of this, cloud cowl turns into decrease in winter rising the power loss. With lowered cloud cowl, virtually no water vapor, and no albedo impact, the Arctic in winter has primarily no feedbacks to the greenhouse impact from CO2. Van Wijngaarden & Happer, notice that
“the comparatively heat greenhouse-gas molecules within the ambiance above the chilly floor trigger the Earth to radiate extra warmth to area from the poles than it might with out greenhouse gases.”
Van Wijngaarden & Happer, 2020
Arctic amplification is the consequence of elevated meridional transport, not the greenhouse impact. The Arctic has a damaging annual power finances (that could be a web stream of power to outer area) and rising the greenhouse impact doesn’t make it much less damaging—that’s warming. Arctic warming, significantly throughout the winter, can solely come from a rise within the warmth transported from decrease latitudes. The rise in Arctic warmth transport that isn’t exported again to decrease latitudes is distributed between elevated radiation to area and elevated downward longwave radiation that warms the floor. The improved downward radiation does enhance the floor temperature, however as a result of low thermal conductivity of ice, and for the reason that warmth flux at all times goes from the hotter ocean to the ambiance throughout winter, temperature inversions generally end result, typically accompanied by humidity inversions. Thus, the radiative cooling continues from the highest of the inversion layer or the highest of the clouds, till the water vapor freezes and precipitates, restoring the unique very chilly situation.
Arctic winter warmth transport is enhanced at instances when excessive stress circumstances prevail over the pole resulting in a weak or cut up vortex. Heat air then enters the central Arctic, displacing chilly air that strikes over the mid–latitude continents producing anomalously chilly temperatures and snow. Since Arctic amplification began, the frequency of mid-latitude chilly winters has elevated, one thing that fashions can’t clarify. One thing comparable befell between 1920–40.
Abstract of the information
Earth’s world common floor temperature varies 3.8°C yearly. The excessive temperature is in July and the low temperature in January. Thus, it’s troublesome to take the IPCC warnings about two levels of warming over the following 100 years critically.
Earth’s tropics obtain way more photo voltaic power than they will radiate to outer area. This units up many elaborate pure processes to maneuver power towards the poles the place the web stream of power is to outer area. Modifications on this power stream may cause local weather change.
Geologists have devised a technique that makes use of Wladimir Köppen’s local weather belts to reconstruct previous world common temperatures. The reconstructions have a really low temporal decision and solely decide one world common floor temperature each 5 million years, however the course of is affordable. Our current local weather is unusually chilly in Earth’s historical past, colder than 90% of the previous 540 million years. Temperatures within the tropics don’t range a lot, world warming or world cooling primarily takes place within the mid- to high-latitude areas.
Storminess will increase in durations with a bigger latitudinal temperature gradient as a result of most extra tropical power from the tropics is transported in storms. As world warming reduces the gradient, fewer storms are anticipated.
Photo voltaic exercise impacts Earth’s local weather, however the correlation adjustments with time. It’s typically optimistic, that’s Earth warms with rising photo voltaic exercise and typically Earth cools with rising photo voltaic exercise. The switches seem to happen each 80-120 years. The local weather/photo voltaic correlation adjustments recommend that the photo voltaic impact on local weather just isn’t straight resulting from adjustments in photo voltaic radiation just like the IPCC proposes, however to photo voltaic induced adjustments to giant atmospheric processes which might be being uncared for.
Arctic summer season temperatures don’t change a lot, in all probability as a result of any enhance in meridional transport merely melts extra polar ice. Winter temperatures do change, extra power transported to the Arctic will heat the floor. When extra ice melts in the summertime, resulting from elevated meridional transport, the refreezing of the ice within the winter causes the launched latent warmth to be despatched to area.
Abstract of Local weather Mannequin issues
The primary severe local weather mannequin that tried to point out greenhouse gases, particularly CO2, that would clarify all, or almost all, of recent world warming was developed in 1979, and revealed by the Nationwide Academy of Sciences. It’s often known as the “Charney Report.” Within the 43 years since that report was revealed, the IPCC has revealed 47 extra reviews that attain almost the identical conclusions about CO2 and local weather. But after writing many tens of hundreds of pages and spending billions of {dollars}, they’ve not satisfied a majority of the folks on Earth, or within the United States, that artifical local weather change is our most necessary and severe societal downside. Different societal issues are at all times thought-about extra necessary and pressing. In a 2018 Gallup ballot local weather change ranked 18th, of 19 points in significance, in an identical 2014 ballot, local weather change ranked 14th on a listing of priorities. A 2022 ballot by the Pew Analysis Middle additionally discovered local weather change ranked 14th. Minds are usually not being modified.
These fashions can’t clarify why the frequency of Northern Hemisphere chilly mid-latitude winters has elevated. They can not simulate the Early Eocene heat circumstances with out utilizing unrealistic CO2 ranges and local weather sensitivity to CO2.
They can not clarify why species variety, particularly mammalian variety, elevated within the Early Eocene, when world temperatures have been ten levels hotter. They can not clarify why there was no Arctic warming when world warming peaked between 1980 and 1997, but it did enhance after 1997 when warming slowed.
Additional, this critically dated speculation was constructed earlier than the invention of all of the multidecadal ocean oscillations and their connections to photo voltaic exercise. Appreciable proof has been uncovered since 1979 that local weather change just isn’t merely a perform of adjusting greenhouse gasoline concentrations, however way more advanced, with quite a lot of pure enter.
It’s particularly worrisome that the Early Eocene warming and the present Arctic warming can’t be defined with the IPCC greenhouse gasoline local weather change speculation. These issues alone are sufficient to invalidate the speculation. Beating a useless horse involves thoughts.
