Ssssssshhhhhh, don't mention Reform.

Their records show that C0² back then was about 880ppm, which suited them just fine.

I am pretty sure they couldn't measure CO2 back then!

Loads of other ways to find out - keep googling and learning about historical Co2 we can trace it back millions of years

I have now. It says 180-280 ppm in Roman times. Not 880 ppm.

When Claudius built hadrians wall he insisted on installing trellis all along the southern side so that they could grow grapes on it.

Co2 was 280ppm back then

Oh and they didn’t measure Co2 back then.

What a surprise Lirefighter, a Brexit supporter, a Reform supporter, a Trump supporter is also a man made climate change denier

I'm sure he'll be along soon enough to claim that everything we've said is lies.
That's all he ever does.

Been measuring Co2 in the atmosphere since the early 1650s

1950s I believe.

 

[Notch7]

been looking for where I said it was good for the planet have you

Aveatry do you believe that crops would grow better if global CO2 levels were higher?

Aveatry CO2 is currently around 429ppm do you consider that to be too high?

 

[aveatry]

At a concentration of about 150 ppm or less, many plants die of CO2 starvation

I have now. It says 180-280 ppm in Roman times. Not 880 ppm.

Go figure - the CO2 levels were les than now and yet the temperature was higher

Roman Warm period anyone ? with lower Co2 than now
Climate alarmists rarely talk about the Roman Warm Period, as they are happy to let sleeping dogs lie.

There are several events like that, such as the Little Ice Age and the Medieval Warm Period. But the explanation given is that these were just regional events caused by things such as temporary changes in sea currents. They weren't global temperature changes. They definitely cause a lot of confusion, though.
