The Erie Canal was threatened by climate change after the Civil War. Only then they knew that agriculture had caused the desertification from Morocco across Africa to the Steppes and Mongolia. In up state New York large swaths of land were cut for timber. In 1874 George Perkins Marsh explained if this continued the Erie Canal would become too shallow for barrages to deliver cargo and New York’s burgeoning economy would suffer. Nearly 10,000 square miles of forest was protected as the Adirondacks State Park to preserve the watershed and stop the warming. The Land Barons were chagrined. So today we only a talk about emissions for climate change, a term coined by Dick Cheney to defuse and misdirect global warming. 100 billion tons of excess carbon dioxide is the problem. Increasing vegetation and soils by 2% would restore the atmosphere to 350 ppm carbon at the expense of the resource extractors.
