I'd like to know if this camera can see Far IR, or if it only sees Near IR (below 3 microns),
which would be outside the range of any real-world 'greenhouse' processes.

But Paul, this is a bit mixed up:
In this "experiment," the candle would represent "the surface of the earth,"
and the camera would be deep space.
It's the effects of outgoing, long-wave radiation (over 3 microns),
which global warming theory describes.

...this undoes science? I thought we already knew CO2 absorbs heat.

It would be nice to see into the tube, from the candle's
point of view, to see if any "back radiation" was evident.

Remember "back radiation" (also known as the 'greenhouse effect')
from this thread?

...overturned the foundations of spectroscopy and atomic theory?

It's no wonder you've been going on about the blocking
of incoming (short-wave, near-IR) heat from the sun
...as "evidence" that CO2 works differently
than over 100 years of study has demonstrated!
