Every person here is breathing out 40,000 ppm CO2
By Jo Nova
Elon is scratching for a reason to keep worrying about CO2
In the interview with Donald Trump, Elon Musk tried to argue that we ought be limiting carbon dioxide because we are too close to 1,000ppm where people get headaches. Not to put too fine a point on it, but we breath out air at 40,000 ppm fifteen times a minute for our entire lives. If 1,000 ppm gave us a headache or made us nauseous, we’d have to hold our breath every time we kissed someone.
@ElonMusk: The point I was making is that, even if CO2 did not cause global warming, it is uncomfortable to breathe air with >1000 ppm of CO2. Given that the outdoor ppm away from cities is now ~420 (lol), it is already getting close to 1000 ppm indoors in cities at times. You can buy a cheap CO2 monitor and measure this for yourself.
As the global base level of CO2 keeps increasing, it will cause air quality in cities to feel stuffy and unpleasant, resulting in drowsiness, poor concentration and eventually headaches and nausea. […]
Apparently human emissions of CO2 have stopped growing in the last few years, but atmospheric levels of CO2 are rising anyway.
IEA data shows CO2 emissions stopped rising:
Global Carbon Emissions, 2017, IEA, Graph.
Pop-Quiz — The correct conclusion from this is:
1/ Human emissions are irrelevant — global CO2 is controlled by ocean currents, phytoplankton, other stuff. Efforts to control global CO2 through windmills and electric cars are a complete waste of money. 2/ Natural sinks have suddenly filled up, the ocean is full, and we are near a tipping point. Panic. Give us your money. 3/ Pretend not to notice, instead, rejoice that Global GDP is still increasing which means that for the first time in 100,000 years, humans have disconnected economic development from burning carbon based stuff. This is proof finally, in your faith that renewables will not cripple economies. (See Scientific American.) 4/ Declare that global emissions are still rising rapidly anyway. (Here is the same award-winning Peter Boyer not researching his claims in 2016. When will he start?)

The terrifying effect of CO2
Feel the panic.
South Pole CO2 levels cross 400 ppm first time in 4 million years!
WASHINGTON: The Earth passed another unfortunate milestone when carbon dioxide levels surpassed 400 parts per million (ppm) at the South Pole for the first time in 4 million years, according to US scientists.The South Pole has shown the same, relentless upward trend in carbon dioxide (CO2) as the rest of world, but its remote location means it is the last to register the impacts of increasing emissions from fossil fuel consumption, the primary driver of greenhouse gas pollution, researchers said.
In response, the South pole temperatures “pause”

What kind of pollution do you want to feed your plants? The carbon kind.
Yet again, a satellite study of leaf area shows that the world is greener than it was in 1982. There are more plants mostly thanks to CO2 aerial fertilization. The biggest benefits from CO2 are in the warm tropics. The extra greenery in colder areas was due to that other disaster called “global warming”. About a tenth of the greening had nothing to do with either carbon pollution or extra warmth and was apparently thanks to nitrogen from man-made fertilizers.
Obviously we need a $10 billion dollar program to stop this immediately.

Humans are Greening planet Earth — ABC
The most comprehensive modelling of remote sensing data so far shows the area on Earth covered by plants in this time has increased by 18 million square kilometres — about 2.5 times the size of the Australian continent — largely due to the fertilising effect of carbon dioxide (CO2).
“[The greening] has the ability to fundamentally change the cycling of water and carbon in the climate system,” said Dr Zaichun Zhu, from Peking University in China and lead author […]
A paper that is nearly 60 years old shows us just how intrinsically important CO2 is to life.
An acre of corn is a living machine drawing CO2 from the air around it. In windless conditions, CO2 concentrations over a cornfield build up each night as CO2 diffuses from higher air and the organic matter and bacteria create CO2 from the soil. A paper by Chapman et al from 1954[1], shows that as soon as the sun comes up, to power-up those dormant photosynthetic cells, the plants rapidly draw down as much CO2 as possible, and when the CO2 levels fall too low, plant growth surely slows.
On a windless day CO2 values rose to 410ppm overnight and fell to 210ppm during the morning.
This graph shows CO2 content of the air over a cornfield on a still day (no wind). Sunrise occurs at 5am and CO2 levels plummet til 8am, reaching their lowest by 1pm, which is nearly half the CO2 concentration of the peak reached overnight. The corn is affecting CO2 levels in air even as high as 150m or 500ft above. These level out by around 8am and only start to increase again, a couple of hours […]

It comes as not even a tiny surprize that when someone asks “Where does all the CO2 go in an ice age?” that the answer is “The Ocean“.
We already know temperatures rise 800 years before CO2 levels (Caillon 2003), and we know the oceans contain 50 times as much CO2 as the sky. Moreover, basic chemistry tells us that CO2 (like all gases) will dissolve better in cold water, and be released as the water warms. To cap it all off, the deep abyss of the oceans turns over once every millenia or so (which fits loosely with the “lag” between temperature and CO2 levels).
But you would think this new research was solving a deep mystery, rather than confirming what most sane knowledgeable people would expect. Nonetheless, this may be the first detailed study of C13 levels going back 24,000 years.
CO2 was hidden in the ocean during the Ice Age
EurekaAlert
Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth’s climate became warmer? Processes in the ocean are responsible for this, says […]
There goes another “fingerprint”…
It’s not just that man-made emissions don’t control the climate, they don’t even control global CO2 levels.
Judging by the speech Murry Salby gave at the Sydney Institute, there’s a blockbuster paper coming soon.
Listen to the speech: “Global Emission of Carbon Dioxide: The Contribution from Natural Sources”
Professor Murry Salby is Chair of Climate Science at Macquarie University. He’s been a visiting professorships at Paris, Stockholm, Jerusalem, and Kyoto, and he’s spent time at the Bureau of Meterology in Australia.
Over the last two years he has been looking at C12 and C13 ratios and CO2 levels around the world, and has come to the conclusion that man-made emissions have only a small effect on global CO2 levels. It’s not just that man-made emissions don’t control the climate, they don’t even control global CO2 levels.
CO2 variations do not correlate with man-made emissions. Peaks and falls correlate with hot years (e.g. 1998) and cold years (1991-92). No graphs are available from Salby's speech or paper yet. This graph comes from Tom Quirk's related work (see below).
The higher levels of CO2 in recent […]
That CO2 you emitted last Tuesday: Is it coming back next month, next year, or in March 3011?
Tim Flannery makes it clear that CO2 circulates o-so-slowly, circa “a thousand years”. Remember that CO2’s “greenhouse” effect occurs at speed-of-light timescales, so if the temperature is affected, so must be the CO2 (according, at least, to the World of Flannery).
If we cut emissions today, global temperatures are not likely to drop for about a thousand years… Just let me finish and say this. If the world as a whole cut all emissions tomorrow the average temperature of the planet is not going to drop in several hundred years, perhaps as much as a thousand years because the system is overburdened with CO2 that has to be absorbed and that only happens slowly. [Thanks to Andrew Bolt]
There are a few clues that maybe CO2 doesn’t idle the centuries away aloft, and that (I know you’ll be shocked) the Climate Commission (and IPCC) have overstated things: If emissions are absorbed by the global system in a matter of months, it rather blows the idea that we have to act decades ahead to stop the catastrophe. If CO2 levels adjust quickly, […]
