you did not change me at all
I said prior and am saying now Im skeptical that 141 ppm will cause the earth the get hotter
I dont deny warming is taking place just what is causing it
but hey theres always tomorrow and I might come to my senses or maybe climate scientists might instead
Ahh. Perhaps with the diversion talking about guns you didn't see or take the time to read this:

It lays it all out pretty well.
The sun bombards the Earth with radiation. The Earth reflects it as infrared radiation. Without an atmosphere, that would just escape into space. With it, we trap that infrared in a "greenhouse effect". But what's responsible for trapping that?
The long and short of it is that 99% of the Earth's atmosphere is nitrogen (N2) and oxygen (O2). These molecules do NOT absorb infrared radiation, and do not contribute in any way to the greenhouse effect. Therefore all of the greenhouse effect is driven by the 1% leftover.
That greenhouse effect was studied in large part because back in the 1800s, scientists estimated that the Earth was
59 degrees Fahrenheit warmer than it "should be" and were trying to figure out why. We "should" have been a lifeless ice ball, but
something was warming us up. It was the greenhouse effect from that 1% of the atmosphere absorbing and retaining infrared radiation from the sun, reflected off the Earth, and not allowing it to escape back into space.
Of that 1%, water vapor dominates the biggest proportion. But it's mostly low and around the Earth, and it is not increasing. CO2 in the upper atmosphere IS increasing, and it is effectively that "last line of defense" to stop that infrared radiation from escaping into space, and that's what's trapping the heat. That's why even though it's only 4% of the 1% that matters, and only 0.04% of the entire atmosphere, it has a VERY important effect.
In the last million years of history, during warm periods we've been at 280 ppm. During ice ages we've been at 180 ppm. Those periods saw global temps 7-15F cooler than now. The last time global CO2 levels were around 400 ppm was
4 million years ago, and global average temps were about 6F warmer than now.
So I highly recommend you give it a read, and come to your senses.
