Prolly great skiing for Steve McKinney wannabes
CO2 definitely absorbs infrared but the dust and gas are different things and yes, they can and do deflect incoming solar radiation resulting in cooling.
FWIW, the strongest, most abundant greenhouse gas in the atmosphere is water vapor.
The next strongest, but not as abundant, is methane.
CO2 is third in strength but is more abundant than methane.
I really enjoyed it.
I happened to pick it up at Marshalls many many years ago as a close out in a VCR pack with another volcano video.
What a find!
I had no idea what it was about but the package looked interesting and I was always on the look out for educational stuff since we were homeschooling.
The one thing I liked, too, was on one of the helicopter passes near the volcano while they were monitoring it, the pilot was saying something and you could hear his voice quavering. He was scared to death.
I loved the Weekly Reader, also that book program, can't remember the name of it, it switched to Tab Books in junior high.
I was time to not bet the spread.
This post reminds me of a number of things. I remembered that when I was a child or my father showed me a National Geographic with the Paracutin story. Also a good spread on mosquitos and their life cycle. I knew that it blew in 1943, so I Googled NG 1944 and 1945. The only thing they had listed was 1945. Then the next day I was at my storage place where I have many old NGs and found those two years. It was Feb. 1944. I knew I was young because my memory is of just being able to look down a little at the magazine lying on the kitchen table. In fact I was only 5 1/2, but the memory is still vivid. I have been fascinated with volcanoes my whole life.
I also tried to climb Popocatepetl when I was studying in Mexico City. A group of about 100 from my college started out. We had crampons and ice axes but no ropes. There were a number of Korean War veterans on the hike, but they would be stopping for cigarettes and I would slowly trudge past them. Unfortunately, it was the first day of my monthly, and by the time I was 400 feet from the top I started feeling ill. I met students coming back who said there were sheets of ice ahead and none of us had ropes, so we all headed back down. The next day I had severe sunburn under my chin, nose and lower lip. When I went to the school nurse, she remarked I must have been with the mountain climbing group. Those who went to Acapulco beaches had a very different sunburn pattern. My younger brother was into serious rock climbing and also climbed Denali. His group was landed by a creek and 4 tons of food and gear unloaded and they were over 100 miles from the mountain. They would each load up, walk 4 miles leave their load and go back for more. I think it took them 3 weeks to get to the mountain. On Popo my last thought was, “Never Again this Insanity.”
I think the first NG I ever saw was a coverless copy that featured an article about the first winter at the South Pole (1957? ah, there’s this: http://www.southpolestation.com/trivia/igy1/1957.html).

Ah here it is, as you remember, the old-style covers weren’t the flashy full-color pic.
