You seem to have conveniently forgotten that today we have some of the lowest atmospheric CO2 levels in our history, in 550 million years it has only been this low once before.
Your 550 million year time scale is completely irrelevant considering human civilization has only been around for about 30,000 years

Our carbon sinks are much greater than what you have been told, otherwise they wouldn't be able to handle mans emissions and CO2 would exponentially grow like you say.
BUT UNFORTUNATELY FOR YOU THIS ISN"T HAPPENING.
CO2 concentrations are growing rapidly. Measuring stations at Cape Grim and Mauna Loa are irrefutable evidence of this.

It's not as though we're shipping CO2 in from Mars, we are using fossil fuels from the Earth which when burnt create CO2 gas that is of the Earth.
We are taking CO2 that is buried underground and releasing it into the atmosphere. Of course that is going to have an effect on our atmosphere.

Who told you that 280ppm was the ideal level of CO2 in our atmosphere when history shows that our CO2 levels in the atmosphere have ALWAYS been much higher.
280ppm is ideal for human civilisation because that is what we have been used to. The level it was at prior to human civilisation is irrelevant because we were not around then.

Can you bottle climate change, I think not my friend.
Climate change has been with us since day dot and will continue to change until the Earth is no more.
Man cannot harness climate change, get that through your head.
The fact that the climate has changed naturally in the past is in fact evidence that the climate can also be changed by human activities. 7 billion people pumping CO2 into the atmosphere is going to cause some changes.
You can bury your head in the sand Ajax but your cut and paste posts show that you have a very poor grasp of scientific principles
