Is anybody aware that the CO2 we (as a global entity) are freeing to the atmosphere comes from plants and animals sedimented millions of years ago which were basically made of it (either directly or indirectly), when the atmospheric CO2 concentration were 2 to 5 times higher than current levels (it must have been fault of prehistoric SUVs, surely) ?
So, we are actually returning the old CO2 back to the atmosphere, not adding into it. Hardly an "unprecedented disaster".

Maybe you should look at what scientists think the global climate looked like at that time. I think you would find that it was a much warmer planet with no polar Ice caps and Ocean levels that were significantlly higher.
It took millions of years for plants, animals, and especially phytoplankton to pull all that C02 out of the atmosphere which caused the earth to cool. That was when the most recent ice age happened.
Essentially, we're still on the tail end of that ice age, but what we're doing by burning all that bottled up carbon and releasing it back into the atmosphere, is putting the pedal to the floor on the otherwise gradual natural warming process.

We need to just star thinking like our wise politicians.
We need a pre-emptive war on global warming.
We need to destroy the planet before the warming does to deny the warming the chance.
Every nation on earth that has nuclear weapons should fire them all, incinirate the planet! End of problem. The war against global warming won!
Our politicians are so smart!

We pump billions of tons of CO2 into the atmosphere each day... how is that
natural???
