Consequences / Re: Pathogens and their impacts

I linked to an updating news blog about the coronavirus on the China, China, China thread,


This subject probably needs a dedicated thread - especially if it proceeds as expected.

Consequences / Re: Decline in insect populations

We had a cottage at Lake Erie in the 50's. The screens had to be cleaned twice a season to clear out the dead mayflies. I was alarmed when I went back to the cottage in the early 2,000's and couldn't find a single one, alive or dead.


A friend of mine who makes movies in the North Bay region assures me that they're alive and well in the north. She apparently spends half her day cleaning lenses and shooting around the swarms. :)
The local loss of mayflies is a huge loss of available protein. I hope the predators have been able to follow their prey.


Last summer I spotted a single monarch butterfly at Port Dover. I hope they've found a new flyway.

Wili, did humans have early population booms (small compared to the last one) coming with the development of old civilizations? What happened to those civilizations?
Although they were ridiculous in size compared with actual.
I can not see any other important difference between the San and a 'civilized' EU citizen than that I see between animals and a 'civilized' citizen: the number of members and the way they take in their relation with their environment. Animals and Sans adapt and enjoy, we have to change everything for our 'benefit'.

(I hope your feeling better nanning. If you look at  https://atmosphere.copernicus.eu/monitoring-air-pollution-across-europe  you'll find that you live in one of the most polluted places in Europe and also searching a bit more you might find links between pollution and health symptoms like yours)
((Hope you're right with your perception of stronger winds, that could help your problems considering that you are right))

I'm not sure that I disagree with anything you've written, and some of your examples have a very familiar ring to them.
Those of us that can improvise & put things back together that never had been assembled properly will find more work than we can handle, but repairing machines designed to fail is damn difficult, doesn't pay worth a damn, and scavenging parts that can be cross used takes lots of space.


New installations are done by minimum wage kids that don't know & don't care. Then they're sent back to fix up their screw ups. ::)


Integrated systems installed at the factory shield the manufacturers. A Johnson control valve has all of the safety circuits built in, but it wholesales for twice the retail price of a valve and all of the safety sensors. Robots built the valve, by now they are probably are installed in the system by robots. The grunts simply attach the supply line, the leads to the (installed) breaker box, and run control voltage to the (robotically assembled) T-stat.


When the flame sensor fails, the grunt throws in a new $valve because it's "integrated".
The last dehumidiator I looked at had the control voltage transformer built into the board! The OEM board cost so much that replacing the unit made more sense to the customer. (and myself)


I'm on my 3d window shaker in the 15 seasons I've been up here. The first two failed because the manufacturer hadn't drilled out oiling passages for the blower/fan motor. I drilled one myself and got an additional season even with the metal filings floating in the oil I'd added, by the time the second one failed for the same reason it went straight to landfill, refrigerant & all.


It's still fun to putter about, but I'd hate to rely on making these patches for a living.


We used to manufacture water source heat pumps from angle iron, sheet metal and off the shelf compressors. We wound our heat exchange coils on an antique threading machine & built the beasts custom by hand. Myself, my partner and his teenage kid. Damn efficient machines built to be repairable!


We produced and installed ~1/wk & filled our spare time fixing up other's fuckups, hustling commercial ice machines & installing/repairing walkin coolers/freezers. My partner got old, I got sick, and his kid is now in charge of Steve Wynn's HVAC department. Life was good! We heated swimming pools while cooling homes, warmed an oversized commercial septic tank once, and generally made systems that the "installers' deemed impossible.


I think those days are gone.


Robots on the factory floor kick out a thousand units/day, and the "installers"/salesmen take a two semester course at night school that hopefully keeps them from burning the customers building down. Thread in some pre-charged lines and sell it as the latest model, its Green and it will Save You Money!!


Bah Humbug!

no worries. I just read that we are actually below rcp 2.6 so nothing can happen...
Where did you read this?

Good, kassy. CO2e is the "real" number.

I think there is reason to be optimistic. During the past 10-15 years solar and wind became economically sound proposals and this shows up in the quickly changing expectations - noone expected such a strong change so quickly (the below chart is telling me that Co2emissions are likely topping out in the 2020s to start going down thereafter:
The danger is that we may hit tipping points and feedbacks in this decade.
