Ancient Man-Made Global Warming and Environmental Engineering

Many Americans doubt man-made global warming because they don’t think humans could so fundamentally change the world. Some believe only God could alter the climate.

Many scientist think that includes ancient man-made global warming.

Stone Age GPS and the Discovery of Hawaii

Polynesians settled Hawaii during the 400’s C.E. They came by double-hulled sailing canoe from the Marquesas Islands in the South Pacific. The trip probably took months, and survival required substantial supplies of food and fresh water. Even then death loomed for any canoe the gods didn’t favor with rain, fish, and good winds. It’s hard enough to imagine making the trip when you know the destination. But how did the Polynesians ever discover Hawaii in the first place?
