Can you with a really good spectrophotometer on a satellite, detect and quantify man made terrestrial CO2 sources?
(no cheating and going for the heat! 15um CO2 spectra only!)
What kind of sensitivity do you need to do that?
PPC?
PPK?
PPM?
PPB?

Why do you need to? Do power plants hide? Is oil, natural gas and coal consumption a secret?

Looks like another normal winter has exposed the myth of
global warming for another year.
Record snow cover and record CO2 vomiting up into the air as Warmists'
hypocritically burn the evil fossil fuels to stay warm?

I'm betting you can't detect them without an exquisitely sensitive piece of instrumentation and that the CO2 IR band for Downtown LA looks just like Joshua Tree.
A planet wide image will be monotonously the same shade, except down wind from active volcanoes.
Why?
Absorption to extinction happens in about 150-130 feet at present CO2 levels.
All a doubling of CO2 will do is lower that point. Overall heat balance of the planet doesn't change.

And still the temps go up, Dave.

"Based on Nye's graphic representation CO2 is up near 500 ppm. Is that accurate?"
We visited the Birch-Scripps Aquarium after the Woodson Fest in 2010. There was a dedicated global warming exhibit which reported 300 ppm CO2 levels in the atmosphere and an all-time record. I have to keep up with the EPA regs (40 CFR parts 98 and 1065) but haven't looked up the latest ppm. If it's now being reported to be 500 ppm, there are questions to be asked. It could be a data quality or instrumentation improvement rather than such a significant spike like that. Maybe Ed or BASE can elaborate.
Recent reports of reduction of CO2 emissions don't mean that the concentration is dropping. We're seeing paper change reductions more than actual ones in other words. This always happens when measuring chemicals in the environment. There's also a lag from a feedback standpoint besides the calculations getting better. Like all of these parameters; 100 years to correct the problem in order to achieve a certain CO2 decrease, 1000 years for 1 degree water temp increase, etc., or something like that.
That's where the scrubbers come in. If we really have that much of an impact with such a rapid result, why aren't we doing it?

Scrubbers at power plants seem like a reasonable idea.
Extracting CO2 from the atmosphere on a planetary scale seems like a very hard problem.

Did it make an important difference, TGT?

Chumphy, I never said all time high. Everyone knows that the Earth has had at least as high or higher a CO2 level as now. We've even had a reduced atmosphere. Much like the inside of your head. So what's your point, buttbrain?

Chumphly, why do you insist on being such a terminal morain, rather than something higher up the hill?

Which of course means, in Chief logic, that man can't cause climate change.,

Chudly, I'm going to try to tame the beast and reason with you. It comes down to us knowing that we have dramatically increased the CO2 level. Can we agree on this fundamental fact? It doesn't matter if it's happened before. Things are different now. The unknown ramifications are the problem. We can only speculate what may result. I hope we don't trigger another ice age. I'd much rather sea level rise than Manhattan under a mile of ice.

What about the droughts? Wars are already being fought over water.

Chudly, this is where AGW really hits the skids IMO thanks to Algore hysteria especially. I think you're trying to say that current weather isn't climate. The media loves Algore sensationalism, not us. The models are archaic. But anyone with any sense will agree that the carbon cycle is critically important and ocean acidification is a real problem.

I observed heavy acorn crop this year in the park.
last year was almost none.
Heavy acorn usually means something big is going to happen (snow/rain)
Watch for it ......
