except the evidence of these periods is being changed or removed

Okay so in a couple years In the 1940s it was warm and in the 70s it was slightly colder so that means the green house effect isn’t real.

You are the one cherry picking data

rubbish

go look for yourself

if you can find an untainted source

there are emails between climate scientists talking about how problematic the 70's cold period is

We can see historical records of how much change the co2 levels change from plants and volcanoes see the drastic change in temperature and see how it changed.

and how they can massage the data to better fit the trend they want to show

Okay I don’t care about a couple scientist somewhere massaging data

I do, when they control the political landscape it's dangerous

I mean I don’t care if they with the broader scope of if something is true or not.

you never adequately explained how high CO2 levels didn't lead to ever increasing temps

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
