Is Climate change REAL?, Is it a THREAT?

RE: Is Climate change REAL?, Is it a THREAT?
By looking at the ratios of carbon isotopes in atmospheric CO2 it has been proven that the increase is from fossil fuels, not some mystery natural phenomenon. Atmospheric CO2 levels are also rising 200 times faster than at any point in the last 650,000 years.

IIRC 640 - 650,000 years is also the interval since the last Yellowstone super eruption which saw insane levels of CO2 released into the air, a few dozen ice ages later and yet here we still are??

Guys dont get me wrong I know changes are happening to the climate be they natural or manmade, but if they are as bad as the ologists and experts claim then the four items I mentioned surely would be the first order of business at the Climate Change Talks, ergo if they are not then things clearly are not as bad as the doomsayers make out?
