Global Dimming Keeping the Planet Habitable

Global Dimming Keeping the Planet Habitable

If you have not already seen it,  visitors to this blog  will have an interest in this 50-min documentary, “BBC Global Dimming Documentary”, via Gail Zawacki at her Wit’s End blog.

It relates to evidence obtained from the three-day aircraft grounding that occurred after 9/11 and the profound effects that just the U.S. Commercial Aircraft Flying has on Earth’s atmosphere. (One degree Centigrade increase  within three days.)
Quoting Professor Guy McPherson ;
“The impact of the aerosol masking effect has been greatly underestimated, as pointed out in an 8 February 2019 article in Science. As indicated by the lead author of this paper on 25 January 2019: “Global efforts to improve air quality by developing cleaner fuels and burning less coal could end up harming our planet by reducing the number of aerosols in the atmosphere, and by doing so, diminishing aerosols’ cooling ability to offset global warming.” The cooling effect is “nearly twice what scientists previously thought.” That this February 2019 paper cites the conclusion by Levy et al. (2013) indicating as little as 35% reduction in industrial activity drives a 1 C global-average rise in temperature suggests that as little as a 20% reduction in industrial activity is sufficient to warm the planet 1 C within a few days or weeks.”
Guy and I both believe a serious economic crash could be the end of us!
None of these risks operate in a vacuum, they are all connected.

Imagine what the carbon footprint of the largest most brutal military on the planet must be?
“According to its own study, in 2013 the Pentagon consumed fuel equivalent to 90,000,000 barrels of crude oil. This amounts to 80% of the total fuel usage by the federal government. If burned as jet fuel it produces about 38,700,000 metric tons of CO2…”

Saving the Planet

SAVING THE PLANET

I have often found myself wincing as I hear people talking about saving the planet. It’s felt wrong!  I can hear the voices of condemnation screaming at me now … ‘What a horrible person you are not to agree with saving the planet.’… but let me explain.

I’m the same age as Geoff Lawton!  Though I think he’s doing better than me!

I was brought up in the 50s/60s. I had two dads, my biological one and my step dad. My father was a left wing, ‘why is the government giving money to the farmers just because they have a drought’ type of person. He was always railing against the government because it didn’t look after the poor people. He was also the one who would order me out of the room so he could spray DDT in the living room to kill the flies. We left when I was 10.

My step dad was right wing. He didn’t believe the government should be giving out free money to people. He believed in self responsibility. What can you do to get yourself out of the situation?  He was also a firm believer in organic farming, no poisons, and natural health solutions. (Yes, I know that sounds counterintuitive, but you’d be amazed how many right wing people believe in self responsibly and growing their own food!)

My teen years saw my parents growing all our produce organically and sharing produce with friends who also grew organically.

In Grade 10, a science teacher gave us a scenario. He explained that all energy can be quantified as BTUs, from the physical energy you put into something, to the energy it takes to make a product. He gave us an example…
