Jupiter's Giant Red Spot is red hot & explained by the gravito-thermal greenhouse effect

A new paper published in Nature finds Jupiter's Great Red Spot is red hot at about 2,420°F or 1,330°C (i.e. almost hot enough to melt steel at 1425°C) and that this observation, 
"could solve the mystery of the unusually high temperatures observed throughout Jupiter's upper atmosphere, which can't be explained by solar heating alone. [nor by a radiative greenhouse effect]"
"Previous heat-distribution models suggested that Jupiter's atmosphere should be much cooler, largely because the planet is about fives times further from the sun than Earth is. So, having ruled out solar heating from above, the authors of the new research found evidence suggesting this atmospheric heating is largely driven by a combination of gravity waves and acoustic waves generated by turbulences in the atmosphere below the Great Red Spot.
"Giant planets like Jupiter are measured to be hundreds of degrees warmer than current temperature models predict. Before now, the extremely warm temperatures observed in Jupiter's atmosphere have been difficult to explain, due to the lack of a known heat source."
In other words, the very hot atmospheric temperatures on Jupiter cannot be due to an Arrhenius radiative greenhouse effect. The atmosphere of Jupiter is mostly comprised of the non-greenhouse gases hydrogen and helium, but does contain small amounts of the IR-active 'greenhouse' gas water vapor. However, the Maxwell/Clausius/Carnot gravito-thermal greenhouse effect perfectly explains the observed atmospheric temperature profile of Jupiter, making Jupiter the ninth planet in our solar system to follow the simple Poisson relationship of atmospheric mass/gravity/pressure to temperature. The Poisson relationship was demonstrated in another recent paper:

Referring to fig. 1 of the paper, we find at 0.1 bar pressure on Jupiter, the corresponding temperature is~112°K, and at 11 bars pressure corresponds to 400°K or 260°F:

Fig 1 from the paper. The dotted line is the atmospheric temperature vs. pressure curve on Jupiter. At 11 bars pressure, the temperature is 400°K or 127°C or 260°F.  
This satisfies the Poisson Relation (which in turn is derived from the Ideal Gas Law) previously demonstrated on 6 8 other celestial bodies in our solar system:


T/To = (P/Po)^0.286 ~= 400°K/112°K = (11 bar/0.1 bar)^.286

where
T = temperature at 11 bars pressure =  400°K
To= temperature at top of atmosphere = 112°K
P = 11 bars
Po= pressure at top of atmosphere = 0.1 bar

and once again demonstrates that the catastrophic anthropogenic global warming (CAGW) theory is a myth, that atmospheric temperatures are controlled by mass/gravity/pressure and are independent of greenhouse gas concentrations on any of these 9 planets with atmospheres, including Earth. Adding additional CO2 plant food to the atmosphere will undoubtedly green the Earth, but Earth's climate sensitivity to CO2 is effectively zero.

Jupiter's Great Red Spot is Also Red Hot, Study Shows

 | 

Jupiter's Great Red Spot is apparently also red hot: The highest temperatures ever observed on the planet were recently detected in the region above the ginormous storm.  
The Great Red Spot (GRS) is a massive storm about twice the diameter of Earth that lies in lowest layer of Jupiter's atmosphere. About 497 miles (800 kilometers) above this humongous storm, astronomers measured temperatures reaching about 700 degrees Fahrenheit (about 370 degrees Celsius) higher than normal, James O'Donoghue, lead author of the new study and a research scientist with Boston University's (BU) Center for Space Physics, told Space.com. 
The new finding could solve the mystery of the unusually high temperatures observed throughout Jupiter's upper atmosphere, which can't be explained by solar heating alone.[Jupiter's Great Red Spot: Photos of the Solar System's Biggest Storm
Generally, atmospheric temperatures on Jupiter are around 1,700 degrees F (around 930 degrees C), with the exception of areas above the planet's poles, which are heated by auroras. Above the Great Red Spot, however, the atmosphere is about 2,420 degrees F (about 1,330 degrees C), O'Donoghue said. 



Observations show that Jupiter's upper atmosphere — above the Great Red Spot — is hundreds of degrees hotter than anywhere else on the planet.

Previous heat-distribution models suggested that Jupiter's atmosphere should be much cooler, largely because the planet is about fives times further from the sun than Earth is. So, having ruled out solar heating from above, the authors of the new research found evidence suggesting this atmospheric heating is largely driven by a combination of gravity waves and acoustic waves generated by turbulences in the atmosphere below the Great Red Spot. The new study was published today (July 27) in the journal Nature. 
Atmospheric gravity waves — not to be mistaken for gravitational waves — occur when pockets of air collide with things like mountains. The resulting effect is similar to when a pebble is dropped into a lake, and ripples then form on the surface of the water.  
Acoustic waves, on the other hand, are sound waves, which means they develop from compressions and refractions in the air and travel upward into the atmosphere. There, they encounter regions of lower density and break, much like ocean waves breaking on the shore. When this happens, the acoustic waves release stored kinetic energy and cause molecules and atoms in the air to move around more, which then raises the temperature, O'Donoghue said.  
"Changes in density around the Great Red Spot will shoot waves in all directions," O'Donoghue added. "We believe that acoustic waves are the majority of the heating cause, because gravity waves tend to ship their energy across the planet, rather than vertically up like acoustic waves."

The GRS is a massive storm that rotates counterclockwise, colliding with the natural flow of molecules in the atmosphere, which are moving opposite the storm. These types of collisions create turbulence that creates acoustic and gravity waves, O'Donoghue said. 
Using data from the SpeX instrument on the NASA Infrared Telescope Facility (IRTF) on Mauna Kea mountain in Hawaii, the researchers were able to measure the temperature of Jupiter's atmosphere, specifically around the GRS.  
"The Great Red Spot is the largest storm in the solar system — it is bigger than Earth itself — so it generates a lot of turbulence that impedes the flow of air in the atmosphere," O'Donoghue said. "It is kind of like when you stir a cup of coffee and you turn the spoon around and go the opposite way. Suddenly, there is a lot of sloshing [turbulence] going on that generates sound waves, or compressions of air, upwards for you to hear."  
The heat generated from the acoustic and gravity waves has a localized effect, which suggests there is a coupling between low and high altitudes, as energy is transferred from the lower atmosphere to the upper atmosphere. Previously, the connection between low and high altitudes was thought to be pretty much impossible because the distance is so vast, O'Donoghue explained.
"This new result from Jupiter provides the first evidence of upward coupling of energy that finds its way from the lower atmosphere to the upper atmosphere," Michael Mendillo, a professor of astronomy at BU, who was not involved with the study, told Space.com. "It's a very interesting observation — even on Earth, this mechanism is not well-studied or understood. If this happens on Jupiter, it is possible that it happens on all planets." 
Giant planets like Jupiter are measured to be hundreds of degrees warmer than current temperature models predict. Before now, the extremely warm temperatures observed in Jupiter's atmosphere have been difficult to explain, due to the lack of a known heat source, Tom Stallard, co-author of the new study and an associate professor of astronomy at the University of Leicester in the United Kingdom, told Space.com. 
"Sometimes, ironically, it is easier to see these features on a planet far away [from Earth]," said Stallar, who advised O'Donoghue throughout his research. In other words, "It's much more difficult to step back and see these broadscale effects … on Earth, so it's interesting to use Jupiter as a 'proxy' for what might be happening on other planets, and that includes Earth."
With the Juno spacecraft orbiting Jupiter, the researchers hope to get an up-close view of the Great Red Spot and isolate where the heat observed in the planet's upper atmosphere comes from. They also plan to study the fine details of smaller storms like Red Spot Jr., to see if there is heating above them as well.

Inconvenient Truth: Most scientists are lousy statisticians; AAAS says "'Misunderstanding and misuse of statistical significance impedes science"

A important article published in the American Association for the Advancement of Science (AAAS) journal Science (June 2, 2016) addresses a very long-standing problem pervasive in virtually all areas of science: statistical and scientific reasoning are often not aligned, and the "misunderstanding and misuse of statistical significance [by scientists] impedes science," according to the AAAS.

The fact is that most scientists have a rudimentary understanding of statistics, typically obtained from a few undergraduate courses in statistics taken en route to a scientific career, yet statistics underpins the critical determination of "statistical significance" of scientific data and the validity of scientific conclusions. Most scientists do not consult statisticians to validate and confirm their statistical conclusions, which inenviably leads to false assumptions and conclusions based upon such simplistic analyses. My own field of science suffers from over-reliance on p-values, arbitrarily considering data with a p-value of < 0.05 to be "statistically significant" or "true," vs. data with a p-value of > 0.05 to be "insignificant" or "false," and thus likely un-publishable. A 'skilled' scientist knows well how to play the game of torturing the data, throwing out outliers, adding assumptions, etc. to lower the p-value to a publishable and "true" "statistically significant" 0.05 or less.

A prominent example is Michael Mann's infamous "hockey stick" global temperature reconstruction, arguably the most widely debunked piece of research in the history of science, debunked by both the Republican statistical experts (Wegman et al) and Democrat statistical experts (North et al). Both Congressional statistical expert evaluations of Mann's hockey stick, in addition to numerous gross statistical errors, faulted Mann for not consulting any statisticians prior to publication of his paper.

Sadly, the article admits that arbitrary assumptions of "statistically significant p-values," which vary widely between different scientific fields, are widely misused and misunderstood by scientists and are "out of alignment" with current statistical reasoning, concluding, "let us hope that the next century will see much progress in the inferential methods of science as in it's substance."

New paper demonstrates the gravito-thermal greenhouse effect on Jupiter is due to pressure, not greenhouse gases

A paper published in Science June 3, 2016, Peering through Jupiter's clouds with Radio Spectral Imaging, demonstrates the gravito-thermal greenhouse effect on Jupiter and that atmospheric temperatures are a function of pressure, independent of greenhouse gas concentrations. Jupiter is a gaseous planet with an atmosphere comprised almost entirely of the non-greenhouse gases hydrogen and helium, yet is capable of generating 67% more radiation than it receives from the Sun, and has estimated temperatures at the Jovian core of more than 20,000°C, more than three times as hot as the surface of the Sun. Jupiter, however, only receives 3.6% as much solar radiation per meter squared as the Earth. The only possible explanation for this "temperature enhancement" or "greenhouse effect" is atmospheric mass/pressure/gravity (the gravito-thermal greenhouse effect of Maxwell/Poisson/Clausius et al), and which is entirely independent of greenhouse gas concentrations. 

Prior work has confirmed the gravito-thermal greenhouse effect on 6 8 planets including Earth, and why this falsifies the theory of catastrophic man-made global warming. On the basis of this new paper, we find the gravito-thermal greenhouse effect also holds for Jupiter and that the pressure vs. temperature curve satisfies the Poisson Relation of the gravito-thermal greenhouse effect.

Referring to fig. 1 of the paper, we find at 0.1 bar pressure on Jupiter, the corresponding temperature is~112°K, and at 11 bars pressure corresponds to 400°K or 260°F:


Fig 1 from the paper. The dotted line is the atmospheric temperature vs. pressure curve on Jupiter. At 11 bars pressure, the temperature is 400°K or 127°C or 260°F.  
This satisfies the Poisson Relation (which in turn is derived from the Ideal Gas Law) previously demonstrated on 6 8 other celestial bodies in our solar system:


T/To = (P/Po)^0.286 ~= 400°K/112°K = (11 bar/0.1 bar)^.286

and once again demonstrates that the catastrophic anthropogenic global warming (CAGW) theory is a myth, that atmospheric temperatures are controlled by mass/gravity/pressure and are independent of greenhouse gas concentrations on any of these 9 planets with atmospheres, including Earth. Adding additional CO2 plant food to the atmosphere will undoubtedly green the Earth, but Earth's climate sensitivity to CO2 is effectively zero.

How the West got healthy and prosperous

How can it be that – after countless millennia of malnutrition, disease,  wretched poverty and early death – so many mostly western nations became healthy and prosperous in just 200 years? Matt Ridley says “ideas started having sex.” Deidre McCloskey opines that equality of social dignity and before the law emboldened people to invest, invent and take risks. Both are absolutely true.

However, as I discuss in this week’s article, a number of other essential factors also played key roles: foremost among them the scientific method and abundant, reliable, affordable energy, primarily from fossil fuels. The results were astounding – so much so that today the big question is, How have so many governments succeeded in preventing prosperity from happening?

Thank you for posting my informative and entertaining article, quoting from it, and forwarding it to your friends and colleagues.

Best regards,

How the West got healthy and prosperous

Vital ingredients included the scientific method and fossil fuels – truths we forget at our peril

By Paul Driessen

Several years ago, physician, statistician, sword swallower and vibrant lecturer Hans Rosling produced a fascinating 4-minute video that presented 120,000 data points and showcased how mostly western nations became healthy and prosperous in just 200 years – after countless millennia of malnutrition, disease,  wretched poverty and early death.

More recently, professor of history and economics Deidre McCloskey provided some clues as to why and how this happened. In a Wall Street Journal article outlining “how the West (and the rest) got rich,” she notes that it wasn’t just Karl Marx’s “exploited workers” or Adam Smith’s “virtuously saved capital, nor was it only Hernando DeSoto and Douglas North’s essential property rights and other legal institutions.

Perhaps the most vital ingredient was that over those two centuries “ideas started having sex,” as author Matt Ridley described the process in The Rational Optimist. It enabled innovators to make discoveries and devise technological wonders, often through coincidental Connections that historian James Burke found among seemingly unrelated earlier inventions, to bring us television, computers and other marvels.

Why did ideas suddenly start having sex? McCloskey asks. One reason was the printing press, which enabled more people to read and share ideas. However, she cites two other principal developments: liberty and equality. Liberated people are ingenious, she observes – free to pursue happiness, and ideas; free to try and fail, and try again; free to pursue their own self-interests, and thereby better mankind.

Equality of social dignity and before the law emboldened people to invest, invent and take risks. Once accidents of parentage, titles, inherited wealth or formal education no longer controlled destinies or opportunities, the innate inspiration, perspiration and perseverance of a Franklin, Bell, Edison, Wright, Kettering, Steinmetz, Ford, Benz, Borlaug and countless others could be unleashed.

“Supposedly inferior races and classes and ethnicities proved not to be so,” McCloskey says. “Ordinary men and women didn’t need to be directed from above and, when honored and left alone, became immensely creative.” That’s an important message in the splendid British television series Downton Abbey, as well: when societal restrictions are relaxed, many can rise to new callings and heights.

Many other factors played key roles in this incredible progress. Two are especially important.
The scientific method begins with an hypothesis about how some component of the natural world works, and a calculation or forecast of what would happen if the concept is correct. Scientists then subject the hypothesis and prediction to experiment. If confirmed by data and observations, we have a new theory or law of nature; if not, the hypothesis is wrong.

This process brought wondrous advances – often through long, laborious tinkering and testing, and often amid heated, acrimonious debate about which hypothesis was correct (the miasma or germ theory of disease), which system was better (direct or alternating current), and countless other investigations.

Abundant, reliable, affordable energy – the vast majority of it fossil fuels – made all this and much more possible. It carried us from human and animal muscle, wood, dung and water wheels, to densely packed energy that could reliably power factories, laboratories, schools, hospitals, homes and offices. 

Those fuels also run equipment that removes harmful pollutants from our air and water, and they ended our unsustainable reliance on whale oil, saving those magnificent mammals from extinction.
Today, coal, oil and natural gas still provide 80% of America’s and the world’s energy, for transportation, communication, refrigeration, heat, lights, manufacturing, entertainment and every other component of modern life. Together, the scientific method and industrial-grade energy enable our Ultimate Resource – the human mind – to create more new ideas, institutions and technologies that make life for poor people in wealthier countries better, healthier, fuller and longer than even royalty enjoyed a mere century ago.

Medical research discovered why people died from wounds; the true causes of malaria, smallpox, cholera and other diseases; antibiotics, vaccinations, insecticides and pharmaceuticals to combat disease and improve our overall well-being; anesthesia and surgical techniques that permit life-saving operations and organ transplants; sanitation (toilets, soap, trash removal) and water purification; and countless other advances that raised the average American’s life expectancy from 46 in 1900 to 76 today for men and 81 for women.

Internal combustion engines replaced horses for plows and transportation, and rid city streets of manure, urine and carcasses, while creating new problems that later generations toiled to address. Today we can travel the world in hours and ship produce, clothing and other products to the globe’s farthest corners.

Mechanized agriculture – coupled with modern fertilizers, hybrid and GMO seeds, drip irrigation and other advances – produce bumper crops that feed billions, using less land, water and insecticides.
Houses and other buildings are built better and stronger, to keep out the cold and heat and disease-carrying insects, better survive hurricanes and earthquakes, and connect their inhabitants with entertainment and information centers from all over the planet, and beyond.

Modern mining techniques and technologies find, extract and process the incredible variety of metals and other raw materials required to make the mechanized equipment and factories required to produce the energy we need and grow or make everything we eat, wear or use.

If energy is the Master Resource that makes all of this possible, electricity is the king of modern energy. Imagine your life without electricity – generated by coal, natural gas, nuclear, hydro, wind or solar facilities, or batteries. Imagine life before electricity, or before the internet and cell phones put the fullness of human knowledge and entertainment instantly in the palm of your hand.

At least one more factor helped to unleash this sudden surge of invention, progress, health and prosperity. A relatively new legal entity, the corporation, organized, harnessed and directed people, money and other resources toward common purposes. A growing private sector – free enterprises and entrepreneurs – put corporate and other ideas, labor and investors’ money on the line, assisted by evolving financial and investment systems and practices, while legal and government institutions provided the ethical and regulatory frameworks within which these entities are expected to operate. 
Numerous “invisible hands” worked together across continents and oceans, often without even knowing their counterparts exist, to bring us products as simple as a pencil or as complex as a cell phone.

So we are left with a profound question. Amid all this health, prosperity and longevity for so many – why do so many still struggle on the edge of survival? Why do two billion still have minimal electricity and another 1.3 people still have none at all? Why do two billion still exist on $3 per day? Why do a half-million still die every year from malaria? five million more from respiratory and intestinal diseases?

The formula for health and prosperity is no secret. It is readily available on your cell phone. Indeed, says Leon Louw, the real “economic miracle” today is not found in South Korea, Singapore or Botswana – but in North Korea, Venezuela and most of Africa.

What should fascinate us is the miracle of poverty – the way inept, corrupt, greedy, centrally planned, hyper-regulated governments have prevented prosperity from happening. What should outrage us is that callous UN bodies, NGOs and activists have imposed their eco-imperialist agendas, and prevented countries from acquiring the property rights and technologies that made so many nations healthy and rich.

What should concern us is that many forces are conspiring to roll back the free enterprise, free speech, scientific method, and reliable, affordable energy that make modern living standards possible. 

Having them now does not guarantee them tomorrow. Failure to safeguard these essential foundations could take us on the path to joining the ranks of the “miracles of poverty” and FRCs: Formerly Rich Countries.

Dr. Willie Soon takes on Bill Nye, the Scientism Guy

Bill Nye the Scientism Guy

Facts don’t support his hypothesis, so he shouts louder, changes subjects and attacks his critics

By Willie Soon and István Markó

True science requires that data, observations and other evidence support a hypothesis – and that it can withstand withering analysis and criticism – or the hypothesis is wrong.

That’s why Albert Einstein once joked, “If the facts don’t fit your theory, change the facts.” When informed that scientists who rejected his theory of relativity had published a pamphlet, 100 authors against Einstein, he replied: “Why 100? If I were wrong, one would be enough.”

In the realm of climate scientism, the rule seems to be: If the facts don’t support your argument, talk louder, twist the facts, and insult your opponents. That’s certainly what self-styled global warming “experts” like Al Gore and Bill Nye are doing. Rather than debating scientists who don’t accept false claims that humans are causing dangerous climate change, they just proclaim more loudly:        
Our theory explains everything that’s happening. Hotter or colder temperatures, wetter or drier weather, less ice in the Arctic, more ice in Antarctica – it’s all due to fossil fuel use.
Climate scientism aggressively misrepresents facts, refuses to discuss energy and climate issues with anyone who points out massive flaws in the manmade climate chaos hypothesis, bullies anyone who won’t condemn carbon dioxide, and brands them as equivalent to Holocaust Deniers.

In a recent Huffington Post article, Mr. Nye “challenges climate change deniers” by claiming, “The science of global warming is long settled, and one may wonder why the United States, nominally the most technologically advanced country in the world, is not the world leader in addressing the threats.”  

Perhaps it’s not so settled. When the Australian government recently shifted funds from studying climate change to addressing threats that might result, 275 research jobs were imperiled. The very scientists who’d been saying there was a 97% consensus howled that there really wasn’t one. Climate change is very complex, they cried (which is true), and much more work must be done if we are to provide more accurate temperature predictions, instead of wild forecasts based on CO2 emissions (also true).

Perhaps Mr. Nye and these Australian researchers should discuss what factors other than carbon dioxide actually cause climate and weather fluctuations. They may also encounter other revelations: that climate science is still young and anything but settled; that we have little understanding of what caused major ice ages, little ice ages, warm periods in between and numerous other events throughout the ages; that computer model predictions thus far have been little better than tarot card divinations.

As for Nye’s assertions that “carbon dioxide has an enormous effect on planetary temperatures” and “climate change was discovered in recent times by comparing the Earth to the planet Venus” – those are truly bizarre, misleading, vacuous claims.

The relatively rapid increase in atmospheric CO2 over the last 30 years has produced only 0.2°C (0.4°F) of global warming – compared to a 1°C (1.8°F) total temperature increase over the past 150 years. That means the planetary temperature increase has slowed down, as carbon dioxide levels rose. In fact, average temperatures have barely budged for nearly 19 years, an inconvenient reality that even the IPCC (Intergovernmental Panel on Climate Change) now recognizes.

This is an “enormous effect”? By now, it is increasingly clear, the proper scientific conclusion is that the “greenhouse effect” of rising atmospheric carbon dioxide is very minor – as a recent article explains. Mr. Nye and his fans and fellow activists could learn a lot from it.

Objective readers, and even Mr. Nye, would also profit from reading a rather devastating critique of one of The Scientism Guy’s “science-is-easy” demonstrations. It concludes that the greenhouse effect of CO2 molecules is of course real, but Mr. Nye’s clever experiment for Al Gore’s “Climate Reality Project” was the result of “video fakery” and “could never work” as advertised. When will Messrs. Nye and Gore stop peddling their Hollywood special effects?

For that matter, when will they stop playing inter-planetary games? Mr. Nye and the popular media love to tell us that carbon dioxide from oil, gas and coal could soon turn Planet Earth into another Venus: over-heated, barren, rocky and lifeless. Princeton Institute of Advanced Study Professors Freeman Dyson and Will Happer show that this is utter nonsense.

For one thing, Venus is far closer to the sun, so it is subjected to far more solar heat, gravitational pull and surface pressure than Earth is. “If we put a sunshade shielding Venus from sunlight,” Dr. Dyson notes, “it would only take 500 years for its surface to cool down and its atmosphere to condense into a carbon dioxide ocean.” It’s not the high temperature that makes Venus permanently unfriendly to life, he adds; it’s the lack of water.

Second, the amounts of atmospheric carbon dioxide are grossly disproportionate. Earth has barely 0.04% carbon dioxide (by volume) in its atmosphere, whereas Venus has 97% and Mars has 95% CO2. Mars much greater distance from the sun also means it has an average surface temperature of -60°C (-80°F) –underscoring yet again how absurd it is to use planetary comparisons to stoke climate change fears.

Third, Earth’s atmosphere used to contain far more carbon dioxide. “For most of the past 550 million years of the Phanerozoic, when multicellular life left a good fossil record, the earth’s CO2 levels were four times, even ten times, higher than now,” Dr. Happer points out. “Yet life flourished on land and in the oceans. Earth never came close to the conditions of Venus.” And it never will.

Fourth, Venus’s much closer proximity to the sun means it receives about twice as much solar flux (radiant energy) as the Earth does: 2637 Watts per square meter versus 1367, Happer explains. The IPCC says doubling atmospheric CO2 concentrations would be equivalent to just 15 W/m2 of additional solar flux. That’s nearly 100 times less than what Venus gets from being closer to the Sun.

Fifth, surface pressure on Venus is about 90 times that of the Earth, and strong convection forces increase the heating of surface air, he continues, making Venus’s surface even hotter. However, dense sulfuric acid clouds prevent most solar heat from ever reaching the planet’s surface. Instead, they reflect most sunlight back into space, which is “one of the reasons Venus is such a lovely morning or evening ‘star.’”  

Of course, none of these nerdy details about Earth-Venus differences really matter. We already know plant life on Planet Earth loved the higher CO2 levels that prevailed during the Carboniferous Age and other times when plants enjoyed extraordinary growth.

However, even burning all the economically available fossil fuels would not likely even double current atmospheric CO2 levels – to just 0.08% carbon dioxide, compared to 21% oxygen, 78% nitrogen, 0.9% argon and 0.1% for all other gases except water vapor. And doubling CO2 would get us away from the near-famine levels for plants that have prevailed for the past tens of millions of years.

Carbon dioxide is absolutely essential for plant growth – and for all life on Earth. Volumes of research clearly demonstrate that crop, garden, forest, grassland and ocean plants want more CO2, not less. The increased greening of our Earth over the past 30 years testifies to the desperate need of plants for this most fundamental fertilizer. The more CO2 they get, the better and faster they grow.

More than 70% of the oxygen present in the atmosphere – and without which we could never live – originates from phytoplankton absorbing carbon dioxide and releasing oxygen. Keep this in mind when Bill Nye The Junk Science Guy tells you carbon dioxide is bad for our oceans and climate.
