book: Event Horizon: Home Prometheus and the....
 
I have this on loan and am 32-pages in.
It'd dense with data, references are given right at the reading, simplified explanations, correlations with past climate, and comparison to present. Implications.
A 'small' book.

slow progress
 
I've slogged my way to page-76.
Since it's a 'loaner', I'll have rely on notes once I return it.
The material to too important not to get right, so I'll hold my comments until I complete it. If there's any context that I haven't picked up on, I hope to sort that out by the conclusion.
The 'dots ' are well presented.
The 'dots' are 'connected' well.
The picture emerging from the connected dots doesn't bode well for us.
Buckle up!

Editorial Reviews
From the Back Cover
Looking into the future produces fear, an instinctive response that can obsess the human mind and create a conflict between the intuitive reptilian brain and the growing neocortex, with dire consequences.
Have you got to the part about birds like hawks, black kites and fire raptors yet?

It's been mentioned tangentially, but not specifically as of page 76.

finished the book
 
Tuesday evening I finished it.
I took 23-pages of notes to create a little 'pamphlet' for reference.
Glickson took the five major extinction events as analogues to compare to our current situation.
Basically, the current increase in greenhouse gases and attendant temperature, when normalized for atmospheric sulphate aerosol masking, and allowing for changing albedo, is exceeding anything ever experienced in the planet's geologic history.
We are presently inside the sixth mass extinction, and the extinction rate will likely exceed anything experienced before, and on a timescale faster than ever experienced before. Animals cannot evolve fast enough, nor plants move northwards, or to higher elevations fast enough to outrun the heat.
At 350 ppm atmospheric Carbon-dioxide concentration-equivalency, we were at the tipping point for Arctic and Antarctic ice sheet instability.
We're presently at 500 ppm-e.
The last time Earth had this much greenhouse gas in the atmosphere, it was 4-C warmer, and sea level was as much as nine-meters higher ( 29.5-feet ).
The poles are warming twice as fast.
What's going to get us is the permafrost melt and methane clathrate sediment outgassing from the sea floor. Already underway.
Carbon-dioxide lasts for 1,000-years in the atmosphere.
Methane bio-degrades to carbon dioxide, and that will be around for a thousand years.
Every meter of sea-ice loss increases solar forcing by 0.70 Watts/ meter infrared absorption.
As we lose the ice caps, we lose their ability as two of the greatest solar reflectors ever known.
As oceans warm, they expand, amplifying coastal inundation.
As oceans warm, evaporation increases, fueling super-cells, atmospheric rivers, rapidly-intensifying tropical cyclones, extreme rain events, hail, tornados, floods, road washouts, crop destruction, etc..
As oceans warm, carbon-dioxide solubility declines, and what became a carbon 'SINK' will become a carbon 'SOURCE'.
Ocean acidification will prevent shellfish development ( bio-calcification )
This has already happened with ten of the twelve World Heritage Forests.
Bushfires. Forest fires. fire storms. Sink holes. Heat stress. Heat stroke. Heat death. Tropical disease. Peat bog methane release. Desertification. Poleward shift in storm tracks. Disruption of vegetation. Mountain glacier loss. Record melting. Mammal extinction rate is up to 100 X former rates. Vertebrate extinction rate is 100X former rate. Meltwater-induced subsurface ocean warming. Low-density meltwater thermohaline cycle modification of oceanic currents, weakened polar jet boundary, polar jet stream excursions. Loss of vegetative evaporative cooling. Weakened evapotranspiration hydrologic cycle. Differential precipitation. Differential feedback mechanisms. Non-linear feedback mechanisms. 'Wandering westerlies.' Crop failures. Malnutrition. Malaria. Dengue fever. West Nile fever. Zika Virus. Meningitis. Food spoilage. Vector-borne disease.
Too much to list.
Some material would not be within the spirit of constraints here at EcoModder, so I'll just skip all that.
Those more interested will give it a look.
I' learned some things. Time well spent. No regrets. Thanks to Mr. Glickson.

I've seen Event Horizon the horror film, and it's pretty good for that genre that I don't typically care for. Prometheus was a real letdown for me because the story doesn't advance much compared to the duration of the film.

You do of course, understand that, I'm talking about a recent book by PhD Andrew Glickson?

:P

We all know humanity is likely doomed by their own technological prowess, which is why that's the theme of most every dystopian sci-fi.

Technology is the only thing that could save humanity from something like a world ending asteroid, but it's always a double-edged sword. Technology is also the most likely existential threat.

Unintentional manipulation of the outdoor thermostat is nothing compared to humanity's capability to intentionally harm. Killer drones are a bigger menace to one's "environment" than it being slightly warmer this year than last, and all that entails.

Ignore the killer drones, conventional warfare will win (lose?) first. When resources get extremely limited things go boom at places where there are sufficient resources.

If you liked the early-Eocene, 50,000,000-years ago, you'll love the near-future.
Personally, I was enjoying the Holocene.
