Yes, the CO2 Hoax. How come that plants grow better the more CO2 is in the atmosphere? Why do farmers flood the greenhouses with > 1500 ppm CO2? How should the CO2 "greenhous gas effect" work? Enlighten me, 'cause I'm a physist and don't know much about spiritual enlightenment.
BTW, you don't synthesize methane from atmospheric CO2.
Yeah since CO2 is toxic to plants above 10,000 ppm it would be bad to flood greenhouses with that much CO2.
I assume you're joking about not knowing the origin of the term "greenhouse gas effect."
Tell that to Elon Musk who intends to synthesize methane via the Sabatier process from the CO2 in Mars' atmosphere and other researchers who have successfully achieved it here from CO2 in our atmosphere.
That's no joke. e.g. Medical canabis is raised at ~ 15000ppm. Plants starve to death at ~ 150-200ppm. We have now ~ 400ppm. That's about the same level as in ~ 1850, when atmospheric CO2 was measured the first time. For comparsion: water on the moon is present at average ~ 150ppm to 500ppm.
And for the fun of argument: please provide a laboratory approved mechanism how CO2 achives what it is said to do (no, magic is not lab-approved). If you can, then congratulations, you just solved the worlds energy problems.
Oh, btw, if you think CO2 has to be removed from the atmosphere just grow forests. It's cheap and better than everything mankind can do. But be in for a surprise: CO2 is going to rise the more plants you breed.
Is putting a small amount of CO2 in a glass container of air and subjecting it light along with a container of pure air and noting the difference in temperature rise and the reversing the role of the containers to eliminate the possibility of container effect not a valid experiment? I'm no "physicist" but that sounds like a valid test to me.
Only if you're smoking your own product. 1500 ppm is the cutoff after which your returns diminish.
That sounds like a big error....

Yep: (435-275)/275=58% error.
Ocean acidification due to CO2 isn't beneficial. How acid does the ocean need to get to dissolve calcium carbonate shells?
Plants only absorb CO2 during the day, during the night they use oxygen.
You measure CO2 on an active vulcano ... what could possibly go wrong?
On the upwind side, in the trade winds, next to one of the biggest oceans.
But if you think there’s been a steadily increasing, slow volcanic eruption causing that graph, go ahead.
Hi,
If you haven't got room for your solar farm, you used someone else's land and run a 4,300km extension lead.
Tom.. 
Wow!
Enough power to run a DeLorean Time Machine!
1.21 Jigawatts?!
(I love that the script said "gigawatts" but Christopher Lloyd pronounced it wrong... and it stuck.)
Yes, now in Movie folklore.
Tom..
There's a lot of dispute about whether "jiga" is wrong, or an acceptable alternate pronunciation.
I always assumed it was a bit of fictional licence, that it was never intended to be correct, it was intended to sound like a very big number without actually being a specific real big number.
Google: top searches on CO2 percent
According to data from NASA, the CO2 concentration in the atmosphere in 1890 was approximately 294.4 parts per million (ppm).
According to most scientific data, the CO2 concentration in the atmosphere around 1850 was approximately 280 parts per million (ppm), considered the pre-industrial level before significant human-caused emissions began to rapidly increase the concentration.
15000 ppm is 1.5%. You would not enjoy living in that, always feeling out of breath because CO2 stimulates breathing reflex.
What gets generated is EMF. EMF raises voltage, demand lowers it.
I had industrial park customers that I got to use line conditioners on all their computer gear. Line VAC varied by 10V to 15V at times.

For all of you who cannot read it:
In the years from 1827 to 1829, Saussure carried out no fewer than 225 experiments on the carbon dioxide content of the air in the vicinity of Geneva…In Chambésy, a small village near Geneva, on a dry, airy meadow with clayey soil, which lies 16 meters above Lake Geneva, the average carbon dioxide content was found to be 4.15 volume units in 10,000 volumes of air, 4 feet above the ground, according to an average of 104 observations made at all times of the year and day. The maximum was 5.74, the minimum 3.15.
CO2 in 1827-1829 was in the range of 315ppm to 574ppm in Geneve (swizzerland) - Note: not constant, but variable depending on when an where it's measured.
Apply a bit of thinking to this:
CO2 now is around something over 400ppm, maybe 420ppm.
Since industrialisation we have added billions of tonnes of CO2 to the atmosphere, indeed we are adding billions of tonnes every year. Given that we are adding so much is it likely to have gone up? Gone down? Stayed the same?
Added to that, I'm going to take the measurement results found by Saussure as being honestly reported. I'm guessing they are the first or at least very early measurements. Given when they were done I'd expect modern techniques to be more accurate. Modern measurements will also be taken in more places around the world. Saussure's measurements might well have been an honest attempt to find out how much CO2 was in the air in the early 19th century, that does not make them either correct or representative of the atmosphere of the whole planet.
What are the measurements taken today, in the same locations used in 1827-1829, using the same instrumentation originally used?
The proximity to Lake Geneva is also a factor, that appears to be a know emitter of significant amounts of CO2.
Ah, yes. The idyllic pre-Industrial Age era. No bad weather events occurred at all before humanity's Original Sin, our Fall from Grace with Mother Gaia, if you will.
My Canadian Carbon Wealth Redistribution Tax is fixing this, not to worry. We shall tithe in perpetuity an ever increasing sum of Maple Rubles to Emperor Justine I, that He may jet set around the world to speak of the successful Progressive Socialist movement of Dear Leader's perfect society.
We are also thankful that our legally owned property is being seized to give to the Ukrainians to fight, because my daughter's scary looking pink "assault-style" .22 GSG-16 is exactly what is needed to thwart the actually military arms of the Russian Army.
