Climate craziness of the week – global warming blamed for increase In Major League home runs

“…thinner air” cited by sports broadcaster

Scene from live broadcast - click for video

From DeadSpin’s Timothy Burke:

Tim McCarver Blames Global Warming For The Increase In Major League Home Runs

We’d normally save this sort of thing for McCarve’d Up (which will be back next week after being pre-empted for NFL draft coverage) but Tim McCarver said one of the stupidest things ever spoken on a television broadcast today, blaming global warming for “making the air thin” and thus leading to a rise in home runs.

Climate change, or in McCarver’s words “climactic change,” is the culprit (and not, say, steroids, the age of which McCarver insists is over). Global warming is a real thing (climate change deniers are already giving McCarver a beatdown online) but the theory it’s led to increased major league offensive production is one of the most insane things ever asserted by a professional broadcaster. And this man is in the Hall of Fame! [Fox]

Maybe we should just consider ourselves lucky that the King of Baseball Trivia hasn’t yet charted out home runs per ppm CO2 or ACE, along with all he rest of his irrelevant correlations. Sad to say McCarver can really almost ruin a baseball game by insisting on revealing to us his endless nonsensical correlations, and I’m a loyal St.Louis Cardinal fan! [McCarver was a Catcher for St.L. back in the day, and the story the great Bob Gibson told on this same ‘climate change’ broadcast about the first time he met Willie Mays is still quite funny: until he met Gibson off the field at his home in San Franciso, Mays didn’t know that Gibson always wore glasses so that he could see well enough to function normally…except when Gibson was pitching! According to Gibson, Willie was pretty well shook!]

Well they aren’t likely to change the name of the whirled series any time soon; but I understand there is a move in the NFL to change the name of that game to “Please don’t kick the ball !”

Warmer weather in the spring could lead to more home runs. For those of you who have tried to hit a baseball (or golf ball, or whatever) you know how much it can sting when it is cold out. In addition, players will tend to stiffen up more in cooler weather.
However, warmer weather in mid summer could lead to more exhaustion and lessen the ability to focus. This would likely lead to fewer home runs.
I don’t think it’s crazy to say that weather extremes could lead to changes in player performance.

April 29, 2012 4:42 am

While the concept of “GW” may be dubious, we were certainly in the warming portion of the 60 yr weather cycle from ~’75-’05 when HR production was up. Many factors contributed to that: new, smaller parks, lighter bats in use, bigger players, etc. But both theoretical considerations & empirical evidence show that a baseball can be hit significantly farther in warmer, drier, thinner air than in cooler, more humid, thicker air. (Pitched balls don’t break nearly as much either.) Cf: “The Physics of Baseball,” RK Adair,PhD. Pitchers hate playing in Denver. Hitters love it.
Another good McCarver story: in a tight spot in a WS game, McCarver called time to go out to give advice to Gibson. Gibson came toward him scowling and yelled at McCarver, “Get back behind the plate. The only thing you know about pitching is that you can’t hit it!”

Paradoxically, there may be some truth in what he says. Consider the tortoise, it has one of the most efficient wind resistance coefficients in the animal kingdom, it is just built for speed. And yet it is known for its slowness.
Surely an animal that evolved for speed in a thick soupy atmosphere tells us that something has changed, the air has gotten thinner.
And a quick check of the historical records tells us that at one point , in the late aesopolithic, the tortoise was often recorded as being faster than a hare

He’s obviously very confused. The only place the air is thinner is at higher altitudes, due to the lower air pressure. I guess he thinks that the some 75 ppm that C02 has risen the past 50 years has made the air “thinner”, by displacing oxygen. Come to think of it, as I’ve gotten older, I have noticed that with physical exertion I become out of breath more easily. Perhaps he’s onto something.

Tom in Florida
April 29, 2012 5:01 am

Increased home runs probably have nothing to do with building new ballparks with shorter distances to fences. What is known is that when Fenway Park built the sky boxes on top of the stadium behind home plate it changed the wind patterns and home runs at that park decreased.

MattC
April 29, 2012 5:03 am

I would have thought, with global warming’s widely known profound effect on trees, that it would be the wooden bats that have changed to allow more home runs. Seems to me that the thinner air would also mean faster fast balls thus cancelling out the effect on hit balls. Has there been a corresponding increase in pitch speed and strike-outs as well?
Also, we know that the air in a baseball park would obviously have a higher concentration of CO2 because of all the beer. That should mean that the temperature at ball parks would be elevated relative to the surrounding area – I’m going to call this the Beer Heat Island Effect. By closely monitoring BHIE at baseball parks, we’ll be able to see the immediate future effects of higher concentrations f CO2. I’m going to need a grant that includes budgeting for tickets (I’ll need to set up my temperature station somewhere along the 1st baseline), two kosher hotdogs with kraut, a bag of peanuts and, of course, a large test sample of the local beer (unless it’s Busch, this World and everybody in it will burn to a crisp before I drin…. um, test Busch)

Tim McCarver apparently doesn’t know baseball.
It was noted some years ago at Coors field that balls kept in a humidor did not fly as far. Dry balls fly farther. Over time other clubs learned this and now use this as a means of increasing excitement at games.
http://www.baseballprospectus.com/article.php?articleid=13057
For the first seven seasons at Coors, there were 3.20 home runs hit per gamecompared to 1.93 per Rockies away game. However, beginning in 2002 the Colorado Rockies began to store their baseballs in a humidor at a constant 50 percent relative humidity and 700F, as opposed to the more typical 30 percent humidity in Denver. During the period from 2002-2010 the Coors ratio decreased to 2.39, a reduction of 25 percent, while the away game ratio stayed constant at 1.86. Is it plausible that the reduction in home runs can be attributed to the humidor? The primary goal of this article is to answer that question.

Mythbusters confirmed dry balls fly farther
http://mythbustersresults.com/episode83
A dry baseball can be hit farther than a ball stored in a humid environment.
confirmed
The Build Team started off with a small scale test by dropping dry and humid balls from a certain height. The results showed that the dry balls tended to bounce higher than the humid balls. For the full scale test, the Grant built his own rig (dubbed “The Mad Batter”) that could both swing the bat and pitch the ball at the same time. They then tested the rig at a baseball field using humid balls, dry balls, and control balls stored in a normal environment. The results showed definitively that the dry balls were hit the farthest distance and the humid balls being hit the least distance.

Humidor once again under scrutiny
By Thomas Harding / MLB.com | 09/26/10 1:53 AM ET
DENVER — Accusations that the Rockies have uncorked a dastardly plot to slip juiced baseballs into games at Coors Field when they need a lift have bubbled to the level that Major League Baseball became officially involved by having umpires monitor baseballs closely after they leave the storing chamber.

Chad Woodburn
April 29, 2012 5:32 am

It would help if you showed how much the change in air density as it varies with temperature COULD affect the trajectory of a baseball hit at a constant force. Increases in temperature do change the air density, which in turn changes the distance the ball will fly. But how much? Yards? Inches? (For comparative purposes it would be interesting to see how changes in humidity also affect distance.) But please, more science and less sarcasm. I don’t believe in CAGW, but lets prove it not spoof it.

http://en.wikipedia.org/wiki/Coors_Field
In its first decade, the above-average number of home runs earned Coors Field a reputation as the most hitter-friendly park in Major League Baseball, earning the critical nicknames “Coors Canaveral”[10] (a reference to Cape Canaveral, from where NASA launches spacecraft) and “Williamsport” (referring to the site of the Little League World Series). Prior to the 2002 baseball season, studies determined that it was more the dry air rather than thin air which contributed to the more frequent home runs. It was found that baseballs stored in drier air are harder and therefore more elastic to the impact of the bat.

“I (don’t?)suppose that I need tell anyone with an education that a warm, moisture laden atmosphere would actually shorten the distance of a baseball given equal bat launching energy and trajectory as opposed to cold and dry …”
Umm… there seems to be some discussion as to whether the ball would fly further or shorter.
But never mind. Everyone knows that Global Warming can make things both hotter and colder at the same time. So I have no trouble believing that it’s responsible for any unusual run of recent records. Or any run of poor performance. Or even any run of perfectly average performances….

shorten the distance
Do I understand correctly the implication is ostensibly due to “increased atmospheric density”?
Not a pilot?
What considerations for load and take-off ‘roll’ does a pilot make for: a) hot, humid day vs b) just a hot day?
Article: Correcting Density Altitude for Humidity

There is nothing in any aircraft manual on how to correct for humidity when calculating density altitude. The formulas all assume 0% humidity. We know that humidity is almost always much higher than that, and that it decreases the density of the air.

Ballooning website with interactive air density calculators: How to Calculate Air Density with and w/o humidity
Book: Rotorcraft Flying Handbook

Moisture (Humidity)
The water content of the air also changes air density because water vapor weighs less than dry air.

Is there some other factor (not accounted for) that would yield a ‘shorter distance’ (outside of air density), since air density does decrease with increasing humidity?

April 29, 2012 6:22 am

Actually, a warm, moist airmass is less dense than a cold, dry airmass. Water vapor is lighter than air, having an atomic weight of only 18 vs.29 for the air. So adding water vapor to the air reduces the average atomic weight. Otherwise, clouds would sink to the ground vs. rise up into the atmosphere. Cold, dry air offers more resistance to a baseball, reducing its flight.
However, the theory that GW is resulting in increased home runs is quite ridiculous. In addition, the globe has been cooling for the past 10 years, not warming. Not to mention that adding CO2 does nothing to increase surface temps.

It has become so commonplace for the news to run stories about “global warming causes X”, that whenever someone talks about something with no apparent cause, global warming is thrown out as the joke answer.
Woke up with a pain – must be global warming. The dog is barking – must be global warming. Car is running rough – must be global warming. Crime up – must be global warming.
See how useful this is as a technique to explain the unexplained?
In Oz they got rid of weather forecasters because it was discovered that simply forecasting yesterday’s weather today was more accurate than weather forecasts. The same with global warming. We can get rid of all scientists except climate scientists, once we realize that whatever is happening is a result of global warming.

Darrin
April 29, 2012 7:19 am

I seem to recall 15ish years ago the league started wrapping the ball differently. Why? They wanted bigger, better hits for the fans. I’m guessing that has more to do with the number of home runs hit today than AGW does but I could be wrong so will need to study this in more depth. Please send grant money!

Dave Worley
April 29, 2012 7:23 am

A higher density altitude will give a curveball less aerodynamic lift, making it a bit easier to hit.
This might be offset by the denser grass growth due to the higher CO2, making grounders slow down.
If the hit relies on backspin to generate extra aerodyniamic lift, higher density altitude would be a negative influence.
Probably too many variables for Carver to keep in his head.
I expect that sweat on the ball has more effect on the game than density altitude.

It won’t prove “global warming” but it might show more home runs on hot and humid days.

Isn’t Tim McCarver the baseball analyst who sees cause and effect where none exists? When on the air, he is biologically incapable of remaining silent for more than 10 seconds. Someday I expect him to claim a batter swung and missed because his socks were too tight. The next time you’re watching a game with Tim as the color analyst, pay attention to his inane characterizations of what is happening on the field.

Don’t forget the in-flight corrections — your true airspeed (TAS) will be higher than your actual groundspeed due to the pressure differential. Less critical in flight than during takeoff or landing, because your stall speed will be higher in hot-humid conditions.
Not a good idea to judge your approach speed visually when the temperature and dew point are getting within “three degrees of separation”…

Chris… Cold, dry air offers more resistance to a baseball, reducing its flight.
I don’t have a problem with your explanation of what you said concerning density but I did stumble on the above sentence. I’m not disagreeing that the lower density of air (which accompanies the increased water vapour and higher temperature of air) doesn’t promote longer flight due to the inverse relationship between drag and air density….but by only looking at just this one aspect, it ignores several other important factors. For one, the viscosity of the air actually is reduced at lower temperatures. For another, the ball has greater buoyancy in the higher density air. Both of these factors should actually promote an increased distance, no?
I think the difficulty with understanding how things really react is that it is very difficult to look at a specific aspect in isolation i.e. the elasticity of the ball (and the bat for that matter) both change with temperature as does the control of the pitcher’s hands and the stiffness of the batter’s hands to name just a few. This essentially needs a totally controlled test that would eliminate or equalize all the factors in order to just look at the specific factor of what the difference in air does to the flight of the ball. This would mean setting up a machine that could launch a ball at a specific angle and speed (say 15 degrees at 95 mph) on an absolutely windless day. The ball for use in the machine would have to come from a controlled storage where it was kept at specific temperature and humidity. The test would first be done for the low density case of high temperature and high humidity. Then the test would have to be done for the high density case of low temperature and low humidity….. If all the factors were equalized such that the only difference is temperature and humidity, I suspect that the low temperature low density conditions will be the one that gives the furthest distance. My guess is that it is the other factors that make for more home runs in warm weather that have nothing to do with the air……but I’ll also be the first to suggest that such a controlled test could prove me wrong because there was some other factor at play here other than the ones mentioned.

Can any present or ex artillery, sniper types step into the discussion here for real world experience in atmospheric effects trajectory and distance.

Yes. Artillery accuracy (from a surveyed point) depends on such esoteric variables as the temperature of the stored propellant, prevailing winds, free air temperature, altitude of of the projectile’s flight, barometric pressure, ambient temperature, relative humidity, and the curvature of the Earth, all of which will affect range and time of flight, which in turn, affects projectile drift.
Then, after you’ve made all the necessary computations and plugged in the corrections (actually, a computer takes care of that these days), normal dispersion steps in and you miss hitting the pickle barrel by ten feet. But since the bursting radius is fifty meters or greater, you still turn it into splinters…

Let me be more blunt: any ballplayer, including me who continued playing league ball until age 61, will tell you that you can hit a ball farther in warm weather than in cold and farther at higher elevation than at lower– considerably farther, like 50 feet, not just a few inches.

pat:

I suppose that I need tell anyone with an education that a warm, moisture laden atmosphere would actually shorten the distance of a baseball given equal bat launching energy and trajectory as opposed to cold and dry .

This is only true if there is no spin on the ball.
Batters try and get “under the ball”, generating back spin. This actually produces lift, and you get more lift in warm, moist air than in dry, cool air, exactly because of the increased viscosity, and this results in a longer flight trajectory than for with “no spin”. (Hence there are more homers in the hot summer months than in say April, at least in outdoor stadiums.)
This goes under the moniker of the Magnus effect. (The illustration at WIKI shows the example for a ball moving with “forward spin”, which applies to e.g., “sinkers”, and is drawn in the framework of the ball being stationary and the air moving around it, which might be a bit confusing at first. A normally thrown ball has back spin, resulting in a visible “hop”, assuming the thrower has any throwing arm at all).

As a lifelong Cardinal fan and WUWT follower I heard the remark from Mccarver. I immediately remembered that he was a catcher. Catchers equiptment in the baseball community is known as “the tools of ignorance”. Only the ignorant play the position. Even if you’re not ignorant when you put on the equipment a few foul balls or 50 foot curve balls quickly knocks the good sense out of you.

Recall, from your atmospheric studies, balloon/rawinsonde ‘soundings’ (Skew-T diagrams/plots etc) and personal observations during SLF experience aboard commercial airliners even that above ~ 10,000 ft (this can vary) you’ve got dry air (note this is where fair-weather puffy cumulus ‘terminate’ during their rise from ground-based thermals) … so unless you’re limited on flight ceiling RH at cruise altitude is not so much a factor for TAS …

I will have to exception to, and challenge this last assertion on the basis of previously cited characteristics of ‘moist’ humid air (higher RH air, which is less dense) vs dry (lower RH) air (at the same temperature) which possesses a higher density. The ‘spin’ does effectively what the extra length on an airfoil does; providing for increased ‘velocity’ (ball wrt to air) above the ball and hence reduced pressure above the ball; per the Bernoulli principle, allowing the net ‘pressure’ exerted on the bottom of the ball to force the ball upward (this we term ‘lift’). For the same reason that some aircraft must recalculate an acceptable minimum speed for take-off (for higher than normal humidities) to achieve a necessary lift figure, I contend that the ‘lift’ of a baseball hit with back-spin would also be reduced on a ‘humid’ day.
Other factors which were cited above such as the environment the baseballs are stored in (I would call it an ‘environmental soak’ wherein the leather and other ball materials either absorb or release moisture that affects the impact characteristics of said ball when in contact with the bat) before use per ‘experiment and observation’ provided by the Mythbuster crew provides compelling insight into a very important factor affecting the distance a baseball may be hit.

April 29, 2012 5:38 pm

Jim, the Magnus effect depends on the skin thickness around the baseball. The larger the skin thickness, the greater the effect. The skin thickness is a function of the viscosity of the atmosphere and increases with increasing absolute humidity. For a relatively slow moving ballistic object like a baseball, I think the extra lift you get from Bernouli’s effect will outweigh the increased drag on the object.
The lift on a jet plane’s wing (including commercial jet airliners) isn’t primarily from the Bernouli effect, but from the angle of attack of the wing (supersonic-capable jet fighter wings cross sections are nearly symmetric for example). If you rely on asymmetric wing shape for lift, you get too much drag at high speed.
For a propelled object like an airplane that relies on momentum transfer generating lift, the thicker skin depth is just a drag term, and since it doesn’t contribute to the plane’s lift, I can see how it would require a larger net force for takeoff. I don’t have a reference that says humidity affects the take-off speed though. Do you have one?
I agree of course there are a lot of other facts that are at play besides humidity and temperature in how far a baseball will travel, given an initial set of conditions (e.g., velocity and spin vectors).

Alvin W:

No doubt the angle that the ball leaves the bat affects its trajectory too, lol.
I was just considering places where humidity (and other state variables of the atmosphere) affect the trajectory of the baseball, given an initial velocity vector. I doubt humidity has any direct effect on the angle that the bat is swung at for example. 😛

April 29, 2012 6:24 pm

Kind of answering my own question to Jim. Here’s the FAA manual covering the relevant part. See in particular the discussion of “density elevation” versus “pressure elevation”, some interesting content there.
It mentions that water vapor, being less dense that dry air, will decrease the density of the air, hence the airfoils will produce less lift. Since warmer air can hold more moisture (before it precepts) a higher temperature with the same RH will have a lower density. But the effect is very minor.
There’s a calculator here that let’s you play with this.
Some numbers (Temperature in °C, density dry air and density saturated air in kg/m3, and % difference, assuming P = 1000 hPa ≈ 1 atmosphere).
T rho_dry rho_moist %diff
0 1.2753 1.2724 -0.2%
5 1.2524 1.2484 -0.3%
10 1.2303 1.2247 -0.5%
15 1.209 1.2013 -0.6%
20 1.1883 1.178 -0.9%
25 1.1684 1.1546 -1.2%
30 1.1491 1.131 -1.6%
Quite obviously, even in high temperature environments, the effect of moisture on lift (via angle of attack anyway) is very small, and much less important than the air temperature in determining how much lift you get (e.g., the “density elevation” discussed in the FAA manual.]
It would be interesting to look at effect of temperature on airframe drag via the change in viscosity for moist versus dry air. Fun stuff.

Generally speaking, that’s true for altitudes greater than 10,000′ MSL (above mean sea level), unless you’re doing mountain flying — it can get pretty humid in river valleys with bases at 13,000′ MSL; above 13,500, not so much. Most of my flying is at altitudes below 1,500′ above ground level (AGL), and the difference in power requirements between hot-dry and hot-humid is usually less than 3%, but if you’re operating at a high power setting to begin with, that extra 3% requirement can be a show-stopper.

On the stupid sports statement front, a blast from the past.
So Bum Phillips was only partially right. It wasn’t helium, it had to be the global warming running amok when Ray Guy was punting for the Raiders. For those who may not know, Bum Phillips, coach of the NFL’s Houston Oilers in the 70’s, accused Ray Guy, punter extraordinaire, of filling footballs with helium to get the massive hang time and distance he, Guy, attained throughout his career. Phillips even sent a football he retained from a game against the Oakland Raiders to Rice University to have it tested and the results were naturally negative. He should have blamed global warming, except at the time we were headed for another Ice Age. Well, according to all the peer-reviewed work, and the authorative Time magazine..

An actual reply defending this silly assertion:

Climate Stories…
Tim McCarver Isn’t Crazy:
The Home Run And Global Warming Connection. It may seem counterintuitive, but as moisture levels go up, as humidity and dew point rises, air density drops, and (yes) a ball can travel farther through the air, all other things being equal.
Meteorologist Jason Samenow at The Washington Post’s Capital Weather Gang has more:
“Over the weekend, baseball announcer Tim McCarver became the source of ridicule when he blamed global warming as a reason for the increase in home run totals in recent years. But it was the criticism of McCarver rather than McCarver’s comment that was over the top. “There have been climactic changes over the last 50 years in the world, and I think that’s one of the reasons that balls are carrying much better now than I remember,” McCarver said.

OReilly? H2O is lighter than O2 and N2, whereas CO2 is heavier. “Thinning” would mostly result from warming — or altitude. Pitchers hate tossing in Colorado; the balls curve less and get hit farther.
