Large fires and volcanic eruptions have the net effect of cooling the Earth relative to any warming from CO2 involved. Pariculates in the atmosphere have a vastly stronger cooling effect than the comparatively small warming effect you get from CO2, which is the weekest of the greenhouse gases. Most global warming comes from water vapour, of which there is a lot more in the atmosphere; water vapour molecules have a 37% higher heat trapping effect than CO2 molecules, and in the lower atmosphere there are 24 times as many of them as CO2 molecules, so water vapour molecules have about 33 times the global warming effect as CO2 in the lower atmosphere.
The particulates from the 1991 eruption of Mount Pinatubo in the Phillipines, cooled the earth by 1.4°C.
You hint at the reality.
We humans have a hugely inflated notion of our own importance in the Earth's day to day business,while having little respect for the Planet itself.
The Planet has been killing off large chunks of Humanity with regularity for millenia,and is unlikely to stop,even if we install Eamon Ryan as the All-Powerful One.
Interesting article from the Spectator here (may be bahind a Paywall) but here goes anyway.
Right as rain: don’t blame climate change for the British weather
From magazine issue: 21 August 2021
I spend a lot of my life worrying about the climate. When you have more than 100 miles of precious chalk streams under your care, rain becomes the currency of your life. Too much in summer. Too little in winter. Or sometimes the other way around. Other times a bit of both. For us river folk, as for farmers, the weather is never quite right.
Who do I blame when it is not quite right? Well, mostly us. People. Society. Urbanisation. Too many people sucking too much water from too few rivers. Water companies pumping untreated sewage into already critically depleted rivers. Politicians who allow the building of houses on floodplains. Agriculture that gets a free pass to plough, plant and spray pretty much whatever it likes in sensitive river catchments. Do I blame climate change? Not in my darkest moments, no.
Now, I’m no climate change denier — we are daily trashing our planet in a bold bid for human oblivion — but to use a global problem as an excuse for locally sourced destruction is delusional. We have the same water we have always had: the British rainfall total for 2021 will be much the same as it was for 1921, which was much the same as for 1821. At my home, which happens to be a water mill, the wheel still works as efficiently and effectively as when it was updated from wood to cast iron in 1865.
Of course, the counter-argument to this is that British weather is more unpredictable today. We have the right rain but increasingly at the wrong times. Or so it is said. But that is old news. Henry Rider Haggard, of King Solomon’s Mines fame, became a farmer in the later years of his Victorian life, bewailing in his agricultural chronicles wet summers and dry winters, all in sage agreement with his Norfolk neighbours that the climate was irreversibly changing.
I don’t know why it is, but for some reason there seems to be an expectation that British weather should behave as if directed by some super-algorithm that will provide all the weather, at all the times, exactly as we wish it to be. I have this strange paperback book I unearthed when clearing out the house of my late mother. It is not so old, 1993, but it charts the freak weather of Hampshire and the Isle of Wight dating back to 1600.
Here are a few highlights: it rained every day on the Isle of Wight in August 1648, ruining the harvest; in 1703 a tempest in the Solent claimed 8,000 lives; the naturalist Gilbert White recorded the coldest ever day in 1776; a tornado struck Portsmouth in 1810; in 1859 a severe and unexpected October frost caused the mangolds, turnips and swedes to rot; some 22 inches of snow fell in a single day in north Hampshire in 1908; in 1929, generally considered a freakish year, after 136 consecutive days without rain, the water board implemented a hosepipe ban for gardens and motor cars. Sound familiar?
Given that The Hampshire and Isle of Wight Weather Book by Mark Davison, Ian Currie and Bob Ogley runs to 167 pages, I could go on and on. But you are probably getting the idea. And, remember, this is just one relatively weather-benign southern county of England. Yet despite that, the home of the Royal Navy and birthplace of Charles Dickens has a history of notable weather events that would make national — and possibly international — headlines, if repeated today.
The truth is, it is not the climate, it is us. Our expectations are absurd. Snow at Christmas. Bank Holiday scorchers. The perfect wedding day. Over these we lay our massive immolation of the countryside. But guess what? If you build homes in a floodplain, they will at some point flood. If you suck dry the springs that feed a river, it will dry up in summer. If you pollute a river, it — and all that live in it — will die. There is barely any part of Britain that is escaping the predations of what we currently consider the acceptable face of local use and progress.
Yes, we need to save the planet — but first we need to save that tiny bit within which we all live.

I wonder if Easons have that Isle of Wight Weather Book.....🙂
Men, it has been well said, think in herds; it will be seen that they go mad in herds, while they only recover their senses slowly, and one by one.

dont worry about something you can’t control is my philosophy. I do my bit but can’t control the rest of the population actions
The next thing the climate catastrophists will be bleating about is the imminent failing of the Gulf stream - oh look, they have already started: "New signs the Gulf Stream system is near collapse, with ‘Unimaginably Catastrophic’ results for weather in Europe and Eastern US" https://redgreenandblue.org/2021/08/14/new-signs-gulf-stream-system-near-collapse-unimaginably-catastrophic-results-weather-europe-eastern-us/
I have mentioned this before, but it bears repeating: this has happened before, in fact it's a regular event, but everything has to be explained in the context of man having caused every possible climate or weather event. There are no more 'natural' events, they are all caused by AGW - even the Gulf streams imminent collapse, even though it has been slowing for over a millennia. The next glaciation period is upon us, and the climatologists are of course going to blame this next one on human activity - even though it's overdue/right on time - depending on viewpoint, and even though one of the most significant triggers - the halting/altering of the Gulf stream has been happening since well before we were generating appreciable amounts of CO2.
Currently a very large iceberg has broken off the western side of the Ronne ice shelf in Antarctica and is the worlds largest at this time. It's 4320 Km² and is bigger than Majorca. Of course this is being put down to global warming, however, another thing thought to happen at the onset of glaciation periods is that icebergs from Antarctica travel further north than normal. If icebergs that were far bigger than normal started forming, they would be able to drift further north before melting. Of course a significant alteration in ocean currents in the southern ocean could also achieve the same result with smaller bergs. in 2006 a large category 5 iceberg got so far north it reached New Zealand and was visible from the eastern edge of South Island, the first time this has happened since 1931.
If Antarctic ice shelves start breaking up into large icebergs, that of course will be sold as due to mankind and global warming, even if they drift further north than normal and even though research indicates this probably happens normally just prior to glaciation phases starting.
Since I already think the next glaciation period is kicking off, I think the Antarctic ice shelves will soon start breaking up and very large icebergs will drift further north. The panicked shrieking from climate catastrophists and the IPCC will be ear-splitting and the attribution will as usual be AGW, despite it being a known glaciation precursor event.
Don't worry about sea levels rising, the ice shelves are already floating in water so the sea level doesn't rise when they melt, any more than the level of a drink in a glass rises as ice cubes melt.
The OP is correct, the Medieval Warm Period (900-1250 approx) was warmer than today,
You aren't serious comparing modern horticulture with that of a thousand years ago.
