Between the
1600's and 1800's the world went through what has become known as 'The
Little Ice Age'. There was significant glacier movement and disruption
of weather around the world. The result: droughts, crop failures and harsh
winters on a global scale.
Recent results from drilling and analyzing core samples from some of the
world's oldest glaciers have convinced some scientists that we face a
similar 'ice age' prospect in the not too distant future. The melting
of the polar ice caps could bring more fresh water into the Atlantic Ocean
and thus have an effect on the Gulf Stream, an important part of what's
become known as 'The Great Conveyor Belt' which gives the northern regions
of the world a temperate climate.
