Theodor Landscheidt

Theodor Landscheidt (Bremen, 1927 – May 20, 2004) was a German author, astrologer and amateur climatologist.
In 1989, Landscheidt forecast a period of sunspot minima after 1990, accompanied by increased cold, with a stronger minimum and more intense cold which should peak in 2030His work on solar cycles has been cited by global warming skepticsto argue that observed warming is not anthropogenic and will soon be reversed, based on an assumption that fluctuations in climate are controlled by solar activity.
In 1983 he founded and financed the "Schroeter Institute for Research in Cycles of Solar Activity" in Lilienthal, near Bremen. The Institute later moved with him to Nova Scotia, Canada.
