Which leads to the greening of the earth which increases o2 and decreases co2.

No it clearly doesn't. The resulting increase in frequency of severe weather events does wide-scale severe damage of plants ( so no overall 'greening' ) and putting more CO2 into the atmosphere obviously doesn't lower CO2 nor increase O2. There is clear evidence that, since we have been burning fossil fuels to release CO2, atmospheric O2 hasn't increased but atmospheric CO2 has increased i.e. not decreased. so clearly this proves (as if there is a need to prove the obvious) putting more CO2 into the atmosphere results in an increase, not a decreased, in CO2.

What a specious argument, greening of Earth leads to more O2 and less CO2. The present rise in temps world wide is leading to the BROWNING of Earth not the greening. There will inevitably be more desert and less fertile land than today or what was there a thousand years ago. To say nothing of the loss of land mass with rising ocean levels. A lot more places on Earth will become totally uninhabitable due to temperature rises like what we see right now in India and deserts around the world, temps reaching 130 degrees F right now. What will it be like when the same places reach 140 degrees, 150 degrees? I wonder if he has given THAT a thought.
At those kind of air temps asphalt will turn to jello, among other things happening as a result.

Again you are guessing around.
You should ask why was it warmer in some periods than others? Has it to do with CO2 or something else?
Why is it hot on the sun? Because of the level of CO2? No? Then go find the answer about the medieval period. And now, don't guess...

When the Nazis invaded No. Africa in search of oil (of which Germany has none), Roosevelt cut a deal with the Sauds: the U.S. would guarantee the Saud's territory in exchange for cheap petroleum, former. That deal will go by the wayside when America no longer needs the Sauds. The Arabian peninsula will return to being a barren and backwater bit of sand, as it was before WWII.
The Chinese will more than make up for any drop in American oil usage. As their economy grows and consumers buy cars, they will need Saudi oil. They've got 10 times as many potential consumers as the US.

"The resulting increase in frequency of severe weather events does wide-scale severe damage of plants ( so no overall 'greening' ) "
I told you that farmers do more damage to plants when tilling their fields and you ignored this flawless logic. If you are so convinced you are right show us some satellite pictures of severe weather damage where there is less green land than before. I am sure it is far greener than a farmer's tilled field.
Carbon sequestration does happen naturally. It is just a question of how much, so technically you are wrong about that too.

Show me evidence that the earth is browning if you can. I think you are full of it.
Like the Pliocene there is likely to be increased rainfall and less desert land overall if temps rise globally. You do not know what you are talking about. You are just promoting mindless panic.

In the reference link one can read:
"While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change. The gas, which traps heat in Earth's atmosphere, has been increasing since the industrial age due to the burning of oil, gas, coal and wood for energy and is continuing to reach concentrations not seen in at least 500,000 years. The impacts of climate change include global warming, rising sea levels, melting glaciers and sea ice as well as more severe weather events."
