Yet another fucking idiot denier. No one claim man's emissions are higher than natural emissions.
Human emissions pushes the amount of CO2 in the atmosphere higher than te Earth removes it. Man's emissions upset the balance.
That is a God damn fact. Man is the primary case of the increase levels of CO2. That is a God damn fact.
You are not a scientist. Quit listening to Trump & Limbaugh & give a shit about future generations.
