seems the whole world now is sort of in a doomers mindset,... AND do not want to add more bad news BUT as I see things before a problem can be solved, it must first be acknowledged and then understood
long story short basically while most have their heads down looking at "screens" to watch Netflix or post on social media, I have noticed what is happening outside
the other evening for example, looked up into the sky in my back yard (which is pretty close to Downtown San Diego) and saw stars and planets like I have never seen them before,... all because “manmade” haze/smog has diminished
its not rocket science but because of covid-19 and the need to social distance,... people are basically staying at home, so the typical SoCal haze/smog layer pretty much has disappeared!!!
http://www.la.curbed.com/2020/3/26/2119 ... oronaviruswhat people should find interesting is the fact that there is much less man made pollution (not just in the SoCal region but also around the world) AND seems these conditions can be used to test a scientific hypothesis related to climate change
essentially a lingering smog layer along w/ jet contrails act as heat trapping insulators at night, so given the clear skies which is a result of the pandemic we should expect to see a yuge “delta” between daytime and nighttime temperatures (which will confirm that global dimming is masking the global warming effects of CO2)
NARRATOR: September 12th, 2001, the aftermath of tragedy: ironically, as America mourned, the weather all over the country was unusually clear and sunny. Eight hundred miles west of New York, in Madison, Wisconsin, climate scientist David Travis was on his way to work.DOCTOR DAVID TRAVIS (University of Wisconsin-Whitewater): Around the 12th, later on in the day, when I was driving to work, and I noticed how bright blue and clear the sky was, and...at first I didn't think about it, then I realized the sky was unusually clear.NARRATOR: For 15 years, Travis had been researching a relatively obscure topic: whether the vapor trails left by aircraft were having a significant effect on the weather. In the aftermath of 9/11, the entire U.S. fleet was grounded, and Travis finally had a chance to find out.DAVID TRAVIS: It was certainly, you know, one of the tiny positives that may have come out of this—an opportunity to do research—that hopefully will never happen again.NARRATOR: Travis suspected the grounding might make a small, but detectable, change to the weather, but what he observed was both immediate and dramatic.DAVID TRAVIS: We found that the change in temperature range during those three days was just over one degree centigrade. And you have to realize that from a layman's perspective that doesn't sound like much, but from a climate perspective that is huge.NARRATOR: The temperature range is the difference between the highest and the lowest temperatures in a 24-hour period. Usually, it stays much the same from day to day, even if the weather changes, but not this time. Travis had come across a new and powerful phenomenon, one which would call into question all our predictions about the future of our planet.http://www.pbs.org/wgbh/nova/transcripts/3310_sun.html
the circa 2005 PBS NOVA documentary is not “online” for viewing, but there is a link to the BBC global dimming documentary (w/ a Kassandra warning) that outlines how climate scientists made an interesting discovery after 9/11
