Note the size of the human emissions next to the red arrow. (Units are in GT)
On a recent post Obsessed with Human CO2, I pointed out how small is the amount of CO2 emissions from fossil fuels compared to natural sources. Human emissions fall within the error ranges around the estimates from land, oceans and biosphere. This post looks deeper into the issue and our current state of knowledge about attribution of the CO2 concentrations in the atmosphere.
Alarming Claims by IPCC Followers
From Chapter 6 Working Group 1 AR5 with my bolds.
With a very high level of confidence, the increase in CO2 emissions from fossil fuel burning and those arising from land use change are the dominant cause of the observed increase in atmospheric CO2 concentration. About half of the emissions remained in the atmosphere(240 ± 10 PgC) since 1750. The rest was removed from…
