(cid:863) Methane and carbon dioxide spike around 8,000 and 5,000 years ago, due to agriculture, with some argument that these anthropogenic changes interrupted the ice age cycle and prolonged the current inter-glacial. The earth was in a natural cooling period and humans reversed and began to warm the planet again.
