The year 1002 or 1003.
Amerigo Vespucci had two voyages on the easy coast of South America. With these voyages, he discovered that South America extended much further than had formerly been believed leading to the supposition that this was a new continent.
Actually, new scholarship has examined the proof that Vikings landed in the New World long before Columbus or the Conquistadors. Lief Erikson landed on the eastern shore of some unidentified area of North America in the 10th century. The rune stones discovered in Minnesota and Oklahoma seem to support later explorations, and the allegations that Eirik Gnupsson (aka Henricus), Bishop of Greenland made several trips and explorations of Vineland (mainland North America) in the 12th century, but debate rages. (Keep in mind that mainstream archaeology maintained for a century or more that the Clovis people were the first settlers in the Americas, but recent digs have proven the Clovis were predated by--in some cases--1,000 years or more. Simply denying a thing does not make it untrue).
It isn't, really. Yes, the Earth has been warming, since the 1820's. Before that it was cooling, from the late 1600's, and before that it was warming. The world's climate goes in cycles; not only the annual cycles of winter and summer, but cycles hundreds, perhaps a thousand years long. A thousand years ago, the world was warmer than it is now! There were dairy farms on Greenland, and the Vikings called it "Greenland" because it was green. Lief Erikson discovered a land with grape vines which he called "Vinland" (Not big on innovative names, those Vikings). We've discovered Vinland; it's in Labrador, Canada. No grape vines.

Neither. Lief Ericson discovered North America second while Christopher Columbus discovered it third. A Viking did discover North America and his name was Bjarni Herjolfsson. He discovered North America about 200 years before Lief Ericson
