Mankind is burning more hydrocarbons every day than ever before. 500 years ago, humans promarily relied on wood for light, heat, cooking and early industrial processes like iron making. Wood is many times more carbon intensive than hydrocarbons.
True, but 500 years ago there were many times fewer humans and no industrial revolution. The energy consumption today is vastly greater, in addition, there is massive deforestation world-wide causing flooding, drought, and higher temps.
Were it not for the moderating effect of the oceans we would be seeing much greater effect on land.
