I am not a “scientist” but I am a pretty good observer and I’ve observed a lot in my 79 years. Remember at least a couple of things.

1.  The progressive rise in global temperature can VERY accurately be associated with the beginning of the global industrial state, especially the increase in internal combustion engines and coal. The line is linear. It is impossible for this to be serendipitous. So if your theory is correct, and it might be, you cannot discount the rise of toxic fumes from internal combustion engines. 

2.  In areas where internal combustion engines have been altered to decrease toxic fumes, California in the 70s via mandatory cat converters, the amount of “smog” decreased dramatically.   I drove through Pittsburgh several times in the 60s and 70s. The black smoke was so thick, driving was treacherous. Then came Caligiuri who cleaned up the mess and the demand for steel dropped due to Japanese supply. Pittsburgh’s climate is now one of the best in the country.

3.  I’m a very keen observer of warming everywhere I’ve lived. I grew up in Northern Wisconsin because my dad was an avid sportsman. In my town, the lake in the middle of town froze over in winter and fishermen installed heated fishing huts everywhere, some very ornate, some housing illicit girlfriends caught red handed by fleeting visits by wives. I accompanied my dad on numerous occasions. The ice was four feet thick. Cars drove on it, general aviation airplanes landed on it. The only way to get a hole in the ice was by a gas powered drill device. 

On several occasions I remember the air temp being 40 degrees below zero. Tears froze in my eyes. Same for hunting jaunts where in a sleeping bag I was treated to the Northern Lights, I never expect to see again in my lifetime. The snow was so thick it was a local municipal regulation that there must be a red bandana tied to the tip of radio antennas, the only thing you could see coming at you at intersections. No car would start unless outfitted with a heated rod stuck in the dipstick tube, warming the oil so the engine would turn over. The entire month of February stuck at variations of minus 30 degrees F. 

That’s ALL gone now. ALL gone. Winters in my hometown now resemble that of Pittsburgh.

One of the saddest events in my life is when I lost who I considered the brother I never had. He didn’t die, he dumped me because I admitted I believed the reality of global warming. He was my college roommate at the University of Georgia in 1966-68.  We both got drafter at the same time but he elected to join the Marines because they offered him OCS. He survived OCS (he thought they were going to kill him), came out a second Lt, went to Vietnam the same time as me, came back with a chest full of medals and retired to North Carolina a full Colonel. We eventually found each other again and spent over fifteen years motorcycle riding all over the country with another pal from Chicago. We used to talk politics over the Internet and argued a lot since, like most military types, he was a committed right wing conservative. 

One day I happened to mention some of the evidence for global warming. This precipitated a brutal attack on the concept and to me for believing any of it. That I was so incredibly stupid as to accept any of that obvious doggerel meant I was part of the “other” and I was so much an embarrassment he could no longer have anything to do with me. Climate was just normal corrections and anything else was the result of meddling from the left wing. That was about 5 years ago. He never spoke to me again. Broke my heart. 

So the point of all this is that I don’t believe there is one sole reason for global warming but for whatever reasons, it absolutely exists, like God making little green apples and it’s now in the process of destroying our world.  Just look around you. I’ve paid a lot to maintain that opinion.
