Two Natural Components of the Recent Climate Change — Syun-Ichi Akasofu (2009)

What this document is

This is a paper dated 30 April 2009 by Syun-Ichi Akasofu of the International Arctic Research Center at the University of Alaska Fairbanks. Its abstract identifies two natural components of the climate change then under way: first, an almost linear temperature increase of about 0.5°C per 100 years, which the author suggests began around 1800 to 1850 and attributes to the earth’s continuing recovery from the Little Ice Age; and second, a multi-decadal oscillation that the author links to a recent slowing of warming.

The paper argues that the long-term linear trend should be subtracted from the temperature record when estimating the human contribution to recent warming. This is a single author’s interpretation and is not a consensus position; it is provided here purely as an archived reference.
