A different hypothesis is posed here: anthropogenic emissions of these gases first altered atmospheric concentrations thousands of years ago. This hypothesis is based on three arguments. (1) Cyclic variations in CO2 and CH4 driven by Earth-orbital changes during the last350,000 years predict decreases throughout the Holocene, but the CO2 trend began an anomalous increase 8000 years ago, and the CH4 trend did so 5000 years ago. (2) Published explanations for these mid- to late-Holocene gas increases based on natural forcing can be rejected based on paleoclimatic evidence. (3) A wide array of archaeological, cultural, historical and geologic evidence points to viable explanations tied to anthropogenic changes resulting from early agriculture in <\/SPAN><st1:place><SPAN lang=EN-GB style=\"FONT-FAMILY: 'Monotype Corsiva'; mso-ansi-language: EN-GB; mso-bidi-font-family: Times-Roman\">Eurasia<\/SPAN><\/st1:place><SPAN lang=EN-GB style=\"FONT-FAMILY: 'Monotype Corsiva'; mso-ansi-language: EN-GB; mso-bidi-font-family: Times-Roman\">, including the start of forest clearance by 8000 years ago and of rice irrigation by 5000 years ago.
