Yes, but Columbus claimed his Greenland trip was in the 1470s, and the article says it was warmer then, warmer than now? But if it was warmer then and not so warm now... ?
Color me skeptical. The thermometer hadn’t even been invented yet. Columbus had no way to quantify temperature. Nobody schlepped goods to Greenland because there was nobody living there to sell them to. There were a few scattered Eskimos here and there, but they were the very definition of poverty.
Sorry if that bursts bubbles. The article had a host of weird ideas in it.
European powers competing for access to Greenland, as a staging area for advance into a New World they didn’t know was there? You will note how vital the Greenland route was in the later exploration and colonization. /s
Tides much higher than today due to climate change? Unless I’m seriously confused, tides are caused by gravitational attraction of Sun and Moon, not by weather.
Sorry, article strikes me as tin foil kookburger stuff.
