What is caising the current increaes in CO2 (if they actually exist), current warming, warming from 700 years ago, natural cycles, or burning of fossil fuels?

Are you familiar with the multiple lines of evidence that the increase in atmospheric CO2 is anthropogenic?

I guess if you showed them to me then I would be.
I would bet that forest fires, volcanoes, etc., contribute as much, if not more C02 than humans do. If a forest burns, it not only sends CO2 into the air, it burns up a bunch of CO2 consumers (trees) leaving less O2 for us O2 consumers.
