The projected effect of a new Maunder Minimum is a cooling of 0.3C, which would very slightly offset the expected warming of 4C cause by greenhouse gases.
There was 15x the C02, accompanied by far lower temperatures, in the atmosphere during the Ordovician Ice Age than there is now. Earth is not the plastic terrarium you think it is, and the upper atmosphere isn't a hermetic lid for black box radiation.
Untold trillions of pounds of CO2 were emitted from uncontrolled, lightning-sparked wildfires for eons before the mid century invention of the municipal fire department. The whole of corporeal existence is made of the stuff.
And here come the straw men and divergences from the topic.
If you're not even going to be honest about what I'm saying, then what's the point of even having a discussion.
Look at the solar activity during the Ordovician Ice Age... it wasn't even remotely as high as it is today.

sanspeur implies immediately above your post that a little CO2--let alone the 1500% more volume of CO2 during the Ordovician Ice Age over and above now--will more than offset any Little Ice Age cooling.
And point to where anything I wrote in this thread is off topic.
Apparently your brainwashers totally neglected to tell you about the relationship between solar activity and temperature in the historical record.
It doesn't really surprise me that even my extremely basic point flew completely over your head.
OF COURSE there is a relationship between solar activity and temperature. There is ALSO a relationship between Co2 and temperature, but you don't want to hear about it because it doesn't click with your politics.
If solar activity decreases in the 2030s, then maybe the warming will not be as bad... but it doesn't mean that there is going to be cooling. The daily mail is full of morons who want to spin this kind of BS into a story about an Ice Age, and will then next year point to their own misinterpretation and say 'OMG SCIENTISTS ARE SO STUPID IS IT AN ICE AGE OR WARMING LOL'.
Astronomers are more credible - they haven't gone 'post-normal'.
You seem to be under the impression that the term post normal science discredits climate science....Do you even understand what post normal science is?

Conditions 443 million years ago cannot be compared to today because the world was entirely different then...
During the Ordovician, most of the world's land — southern Europe, Africa, South America, Antarctica, and Australia — was collected together in the super-continent Gondwana. Throughout the Ordovician, Gondwana moved towards the South Pole where it finally came to rest by the end of the period. In the Lower Ordovician, North America roughly straddled the equator and almost all of that continent lay underwater. By the Middle Ordovician North America had shed its seas and a tectonic highland, roughly corresponding to the later Appalachian Mountains, formed along the eastern margin of the continent. Also at this time, western and central Europe were separated and located in the southern tropics; Europe shifted towards North America from higher to lower latitudes. The Ordovician Period
The models predicted Mini Ice Age levels of SOLAR ACTIVITY, not mini-ice age temperatures on Earth. But I guess you can't expect people with a third grade reading comprehension to understand the distinction, and apparently neither does the Daily Mail (probably because that's their reader base).
If their models are good, just how much this will offset the CO2-caused warming remains to be seen.
Just so we are clear here. Models predicting low soalr activity will not cause cooling but models predicting high CO2 will cause warming.
You can't have it both ways and while we are on the topic what is more important about the solar data is we know exactly what happened.

Exactly right....According to models low sun activity will lower the predicted 4 degree rise caused by greenhouse gases by 0.3 degrees, for a net rise in temperature of 3.7 degrees...You may call this cooling, but I certainly don't.
So they are warning us of doom and nothing we can really do about it. Likely no one is ready for long term survival in a ice age even artic expeditions depend on those in non-artic conditions. Those living in wilds of even Alaska will tell you that they depend on warmer weather stocking survive.
