Quadrant Online - The Critical Decade: Part I

The scientific advice contained within The Critical Decade is an inadequate, flawed and misleading basis on which to set national policy. The report is emotive and tendentious throughout, ignores sound scientific criticism of IPCC shibboleths that has been made previously, and is shotgun in its approach and at the same time selective in its use of evidence.

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).
