So explained Rhodes Fairbridge of Columbia University, a giant in science over much of the last century whose accomplishments are perhaps unsurpassed for their breadth, depth, and volume. This one man authored or co-authored 100 scientific books and more than 1,000 scientific papers, he edited the Benchmarks in Geology series (more than 90 volumes in print) and was general editor of the Encyclopaedias of the Earth Sciences. He edited eight major encyclopedias of specialized scientific papers in the atmospheric sciences and astrogeology; geomorphology; geochemistry and the earth sciences; geology, sedimentology, paleontology, oceanography and, not least, climatology.

Changes in sunspots and other solar activity, scientists have realized for more than two centuries, correlate closely with the climate of Earth, explaining the ice ages and periods of great warming. But what, Dr. Fairbridge wondered, causes these changes in our sun?

The answer, he discovered with the help of NASA and the Jet Propulsion Laboratory, lies largely in the solar system's centre of gravity. At times, the sun is at the solar system's centre of gravity. Most often, this is not the case-- the orbit of the planets will align planets to one side or another of the sun. Jupiter, the planet with by far the largest mass, most influences the solar system's centre of gravity. When Uranus, Neptune and especially Saturn -- the next largest planet -- join Jupiter on one side of the solar system, the solar system's centre of gravity shifts well beyond the sun.



Dr. Fairbridge's best-known periodicity, which he developed in the 1950s, hypothesized that sea levels had been rising for the last 16,000 years, during which there were periodic oscillations of rise and fall. The Fairbridge curve describing this period -- so named in derision because it offended the conventional wisdom - is now widely accepted. It demonstrates that, even within the past 1,000 years, sea levels have several times changed by up to two metres, and suddenly -- each of these large changes occurred in fewer than 40 years.

Dr. Fairbridge's broader climate change claims -- that celestial changes control Earth's temperatures -- remain controversial, but less so than they were decades ago, when his was a relatively lone voice. Solar scientists with increasing regularity are publishing data establishing celestial origins to climate change on Earth. Dr. Fairbridge saw his Fairbridgecurve theories vindicated, but he won't his celestial claims. This most remarkable individual died a year ago this week, at age 92.




Rhodes Fairbridge, an early expert on climate change, was a professor of geology at Columbia. He received an undergraduate degree from Queen's University in Ontario and a master's degree from the University of Oxford. He was awarded a doctorate of science by the University of Western Australia in 1944 at the age of 30, bypassing the usual PhD prerequisite. During the Second World War, Dr. Fairbridge also served with the Royal Australian Air Force in U.S. General Douglas MacArthur's headquarters as deputy director of intelligence.
