Carboniferous period had CO2 levels ~1500ppm and yet temp was 3~12 degrees higher

why did the high temps not lead to more CO2 and the runaway effect?

it doesn't matter how much time anything has to adapt, your contention is that CO2 produces a temp increase

why did this not occurr during the carboniferous and other high CO2 periods?

Why didn’t it lead to a runaway effect? Because plants grew because of higher co2 levels and took co2 out of the air

you think plants can grow faster than the sun can input energy into the atmosphere?

I don't

for plants to stop a net increase in temp they wouuld have to lock away CO2 at an alarming rate

especially at ~1500ppm

What do you mean input energy into a system? co2 levels change equilibriums so temps raise it doesn’t keep trapping energy for ever

So energy can’t leave

uuhhhh, isn't that what you call the greenhouse effect?

if 400ppm co2 will cause a catastrophic rate of temp increase, what rate of temp increase do you think 1500ppm would produce?

how would plants even catch up?

Catch up with what

the rate of temp increase

it increases with increasing CO2

Do you think if you have 1500ppm of co2 the temperature of earth will keep rising to infinite?

no, that would be ridiculous

So co2 levels and temperature have a equilibrium.

Temperature won’t just keep increasing

To infinity

it should get as hot as venus, if climate scientists are to be believed

No it shouldn’t Venus is 96% carbon dioxide and has a thicker atmosphere. While 1500ppm is waaaaaay less then what Venus has.

We would expect a huge temperature difference and we do

I think Venus has 86 million ppm

It what it says

I've never heard a single climate person talk about equilibriums, it's always about a runaway greenhouse effect

Yes I a closed system

I’m a closed system

Let’s say a jar

The temperature doesn’t increase to infinity

If you shine a light on it

black body radiation and entropy would like a word

it's not a closed system

it can be considered closed for some investigations

As energy levels increase more energy leaves.

Changing co2 changes this

Allowing for more energy to stay to a point till more energy starts to leave

So the temperature is higher

if you continually heat a gas in a container, does it reach an equilibrium, or does it get so hot the pressure increases to the point where the jar explodes?
