Little Ice age
Scientific American
by Edna Sun EXCERPT: February 15 , 2005 — It was only a few hundred years ago that the earth experienced its last ice age. Global temperatures started falling during the 1300s and hit their lowest points in the late 1700s and early 1800s. New Yorkers could walk from Manhattan to Staten Island across a frozen harbor, while Londoners held "Frost Fairs" on a solid Thames River. Glaciers advanced in China, New Zealand, and Peru, and snow covered Ethiopian peaks. Diseases, aided by the change in climate, spread quickly throughout Europe and Asia. Iced waters delayed shipping from ports, growing glaciers engulfed farms and villages, tree lines receded, and agriculture deteriorated, leading to centuries of poor harvests, famine, and social unrest. Though the average global temperature dropped only one to two degrees Celsius below what they are today, the cold spell nevertheless drastically affected life at this time. LINK It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies. –William O. Douglas, U.S. Supreme Court Justice, 1952 |
