%26gt; The earth%26#039;s obliquity Angle decreases by 0.47%26quot; each
%26gt; year, which changes the focus of the sun%26#039;s radiation
%26gt; on earth, resulting in climate shifts. As the
%26gt; obliquity angle decreases, the hemispheres change in
%26gt; basic temperature with the south becoming colder and
%26gt; the north becoming warmer. When the obliquity angle
%26gt; reaches about 22 degrees, it will start to go the
%26gt; other way and the north will get colder again and the
%26gt; south will become warmer. Obviously, and counter to
%26gt; Al Gores unlearned theories, the warming of the
%26gt; northern hemisphere cannot be stopped by man. It will
%26gt; stop and reverse itself. Then the climate shifts we
%26gt; presently experience will be goin the other way. It
%26gt; is pure logic applied to astro-physical law.
%26gt;
%26gt; It has long been recognized that rather than staying
%26gt; constant, obliquity varies slowly with time as a
%26gt; result of external gravitational influences. The Moon
%26gt; and Sun%26#039;s tidal torques on Earth%26#039;s ellipticity give
%26gt; rise to the familiar 26,000-year astronomical
%26gt; precession, while the gravitational pull of other
%26gt; planets, primarily Jupiter and Venus, slowly perturbs
%26gt; the orientation of the ecliptic plane in space. The
%26gt; combined effect observed by Earth dwellers is an
%26gt; ~41,000-year oscillation in the obliquity with overall
%26gt; amplitude typically of about 2°. This oscillation is
%26gt; one of the three Milankovitch cycles that ultimately
%26gt; affect our long-term climatic system and serve as the
%26gt; pacemaker of ice ages. The present-day obliquity
%26gt; happens to be close to the mean value, and we are in
%26gt; the middle of a downswing (see figure (1)). In terms
%26gt; of real distance on the Earth%26#039;s surface, one should
%26gt; see a slow equatorward shift of the tropics by 14.4 m
%26gt; a year-well over 1 km in a century! Astronomy 0% 0 Votes
