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. And the Pentagon’s figures do not include carbon produced by the thousands of bombs dropped in 2013, or the fires that burned after the jets and drones departed.”
The Pentagon’s enormous, unacknowledged contribution to climate change
A reduction in US warmongering would buy the bio-sphere some critical time, fat chance of seeing that happen.

The documentary explains how global dimming fits within global heating, as well as reduced pan evaporation rate. (Sunlight photons serve as the most important variable in water evaporation, and global dimming reduces these photons by about 10%!). Increased small particle pollution turns clouds into sunlight mirrors because of water condensation on the small particles: at least ten times the number of particles and condensation than without the pollution. This greatly reduces the amount of the Sun’s energy coming through the atmosphere. Global heating (GH) due to CO2 tends to increase average atmospheric temperature while global dimming (GD) tends to reduce it, therefore reduced GD will greatly increase GH, within days, just as Professor Guy McPherson has emphasised in many of his presentations.

Guy  McPherson references this documentary often and we will be speaking about this phenomenon on his upcoming November 2016 New Zealand speaking tour.
Guy discusses the phenomenon here .

When the Industrial Revolution grinds to a halt and we cease emitting particulate pollutants into the atmosphere, more solar radiation will hit the earth and the oceans, vastly increasing the warming which will compound all the other effects happening now, remember also though there is a 10 to 30 year lag in cause and effect with our emissions and the ones now being generated as a result of the multitude of feedback loops that are now kicking in .

Yet more evidence that we are absolutely fucked and can’t turn this unfolding catastrophe around. Brace for imminent impact, ” Only Love Remains” GMP.

    My co-host on Nature Bats Last has begun a series monitoring the stock market because of our concerns about the loss of the aerosol masking effect associated with lockdown, the rapidly building economic depression and the attributable increase in warming.
    This article proves that that particular feedback is in play.
    To quote “President Niinistö in North Russia: ‘If We Lose the Arctic, We Lose the World’.
    This is another nail in the Arctic coffin, our planetary thermostat is irrevocably broken and the warming will be non-linear.

    “Their study, sponsored by NOAA, was published last week in the journal Nature Geoscience. It concluded that the thin screen of smoke hanging in the troposphere, which extends to about 6 miles above the Earth, dims the sunlight reaching the planet.”

    “The total dimming from this widespread but dilute smokescreen is roughly equivalent to the dimming caused by all the thick, visible smoke plumes emitted from fires.”
    An inconvenient truth;

Kevin Hester is currently living on Rakino Island, a small island in the Hauraki Gulf near Auckland, New Zealand, monitoring the unravelling of the biosphere and volunteering at the Rakino Island Nursery is currently developing a proposal to create a marine reserve near by. The Island has no grid tied electricity or reticulated water.  I catch my own water from the roof and generate my electricity from the ample solar radiation on the island.
