Specifically, they seem completely unable to comprehend powers of ten or orders of magnitude. For example, most of them don't have a working grasp or understanding of the difference between, "million" and "billion"...
Whenever one of them mouths off to me about "Gorebull Wahruming", etc., I give them this simple test:

Typical Lib answers range from, "Over NJ" to "Over DC"...

400 PPM (Parts Per Million) is the Gorebalists' currently claimed figure for the total fraction of the entire atmosphere that is CO2. (The entire" pie", below...)
But, the total fraction of that 400ppm "pie" contributed by all of humankind since the start of the Industrial revolution is 11% of the whole:

Of course, that 11% of 400 PPM (the red "slice") is just 44 PPM!

Going offline now, to put a few more numbers into HTML format. I'll be back with "the rest of the story" -- and to post the answer to the test... ')
Liberals’ emotional reasoning drives them to catastrophism in general, whether equating disagreeing with an official victim group as wanting them dead/hating the whole group or “a little warmer, let’s borrow from the Book of Revelations and sing we’re all gonna fry unless you convert to our faith NOW!”
If I understand the question, youd be somewhere near the end of the runway at JFK.
Easy - about 10 miles from JFK.
Thing is, arguments made on the basis that CO2 is such a small fraction of the atmosphere, it can’t possibly harm you, is not a strong argument.
The amount of a substance need not be big in order to cause serious harm.
“”Botulinum toxin is the most poisonous substance known. A single gram of crystalline toxin, evenly dispersed and inhaled, would kill more than one million people.”
And there are may other substances that can kill you with very small doses.
There are much better arguments based on actual data for debunking the warmist’s religious belief. Here’s an excellent 13 minute video that presents them.

That would be about a mile and 1/8th from the end of the runway.
