I really don't get this. You're all aboard with us having technology for geo-engineering, but you're still refusing to accept that the total output of industrialized civilization and human activity can change the climate? They both work on the same principle - release things into the atmosphere to change the weather/climate - except the latter is several orders of magnitude larger. We are geo-engineering the climate, that's why people are worried.
Emissions are NOT notable drivers of weather fluctuations, no (excessive emissions without regulation/guardrails will have detrimental impact to ecology/the environment, but that's a wholly separate issue). There is no sound evidence of human-based emissions altering the climate in any way that would result in 'imminent' detrimental fluctuations, despite years of programming and blatant propaganda. We can refer to the 'climate change' active thread here to delve into that further.
Re-directing to some of the ostensible 'clean tech' offerings out there (and the incremental steps being pushed by govts to force these -- wasteful, not merely ineffective -- 'solutions'):

This is a Tesla model Y battery. It takes up all of the space under the passenger compartment of the car. To manufacture it you need:
--12 tons of rock for Lithium (can also be extracted from sea water)
-- 5 tons of cobalt minerals (Most cobalt is made as a byproduct of processing copper and nickel ores. It is the most difficult and expensive material to obtain for a battery.)
-- 3 tons nickel ore
-- 12 tons of copper ore
You must move 250 tons of soil to obtain:
-- 26.5 pounds of Lithium
-- 30 pounds of nickel
-- 48.5 pounds of manganese
-- 15 pounds of cobalt
To manufacture the battery also requires:
-- 441 pounds of aluminum, steel and/or plastic
-- 112 pounds of graphite
The Caterpillar 994A is used to move the earth to obtain the minerals needed for this battery. The Caterpillar consumes 264 gallons of diesel in 12 hours.
The bulk of necessary minerals for manufacturing the batteries come from China or Africa. Much of the labor in Africa is done by children. When you buy an electric car, China profits most.
The 2021 Tesla Model Y OEM battery (the cheapest Tesla battery) is currently for sale on the Internet for $4,999 not including shipping or installation. The battery weighs 1,000 pounds (you can imagine the shipping cost). The cost of Tesla batteries are:
Model 3 -- $14,000+ (Car MSRP $38,990)
Model Y -- $5,000–$5,500 (Car MSRP $47,740)
Model S -- $13,000–$20,000 (Car MSRP $74,990)
Model X -- $13,000+ (Car MSRP $79,990)
It takes 7 years for an electric car to reach 'net-zero' CO2. The life expectancy of the battery is 10 years (average). Only in the last 3 years do you start to reduce your carbon footprint, but then the batteries must be replaced and you lose all gains made.
And finally, my new friend, Michael, made some excellent points: I forgot to mention the amount of energy required to process the raw materials and the amount of energy used to haul these batteries to the U.S. sometimes back and forth a couple of times.
But by all means, get an electric car. Just don't sell me on how awesome you are for the environment. Or for human rights.
