"Whether atmospheric warming is perceived as occurring depends entirely upon the period of time under consideration[2]. For example[3]:
Earth has cooled over the last 10,000 years (since the peak warming of the Holocene climatic optimum).
Earth has cooled since 1,000 years ago (the Late 20th Century Warm Period not achieving the temperatures of the Mediaeval Warm Period).
Earth has warmed since 400 years ago (post-Little Ice Warming).
Earth warmed between 1979 and 1998 (Late 20th century warming).
Earth has cooled slightly since 2001 (last 10 years).
That the atmosphere has failed to warm since 2001[4], over the same ten year period that carbon dioxide has increased by ~5% (which represents nearly one quarter of all human emissions of carbon dioxide that have occurred since 1751)[5], is a test for dangerous global warming and its causation - a test that the hypothesis of carbon dioxide causation fails."
