Happy Gardening !
How times change. One hundred years ago when the T-model Ford was replacing horses, people lauded the new fangled horseless carriages as being so much less polluting than poor old Dobbin.
According to ABS, there were 14.5 million passenger vehicles in Australia on 31 January 2019. Let us consider a scenario where each car is replaced by one horse - 14,500,000 horses and most of them in the cities because that is where we live. Sure would generate a lot of manure. Happy times for gardeners!

Very good article from NASA sent to me overnight.
Why Milankovitch Cycles Can't Explain Earth's Current Warming – Climate Change: Vital Signs of the Planet
Key points:
- Milankovitch cycles operate on long time scales, ranging from tens of thousands to hundreds of thousands of years
- Earth’s current warming has taken place over time scales of decades to centuries
- NASA satellite observations show that over the last 40 years, solar radiation has actually decreased somewhat
- Since the beginning of the Industrial Age, the concentration of carbon dioxide in Earth’s atmosphere has increased 48 percent
- In just the past 20 years alone, carbon dioxide is up 11 percent
- the warming effects of carbon dioxide on our planet are 34 times higher than any warming due to the Sun
- Earth is currently in an interglacial period - the Milankovitch cycles predict our planet should be cooling, not warming, continuing a long-term cooling trend that began 6,000 years ago
So that all backs up the argument that CC has always been happening, and always will.
The unfortunate part of relying on that argument for anthropogenic CC denial is that the current natural CC would actually be cooling the planet, not warming it at unprecedented rates.

Paper Blaming Sun For Climate Change Just Retracted From Major Journal
Paper That Blames The Sun For Climate Change Was Just Retracted From Major Journal
But begs the question - why on earth did they publish it to begin with?? Seems like a failure of the peer review process.

I'd like to see the numbers crunched on that. How would the extra methane (another greenhouse gas) produced by that many horses compare to the exhaust gases of as many cars?
I know it's an unfair comparison, but still...
If the numbers were even remotely comparable, I suspect the world would've taken action long before now, even if only because having to continually scrape pooh off your boots is much more... personal.

Unfortunately, it is only in the early days of laboratory research.

Dont mine gold - mine bitcoin?
Perhaps, rather than produce electricity for the purposes of inputting it into the grid - they could become a bitcoin mining operation.
Plonk down a massive solar grid in the middle of nowhere (cheap land!) and pop in a few coin miner machines (automated!) and a satellite uplink....
Minting money the modern way

One of my offspring ran a cryptocurrency mining operation for a while. He lives in the world of high end graphic processing, so has the know how on the required technologies.
Three issues concerned him; you get paid in the cryptocurrency and that is a gamble, returns for miners halve periodically, and, most significantly for him, the energy they consume is profligate in a world challenged with reducing its emissions.
Yes, a solar farm in the desert will not be adding to emissions, but that renewable energy should be put to better use than enabling Darknet trading and unproductive investing.Stay sharp and stay safe!
