Because NASA has extensive research proving that the SUN is raising temperatures across our entire Solar System. We have experienced INCREASED Solar bombardment on the ISS (trying to figure out how to keep our guys from frying on a trip to Mars).
It is in the 2017 to 2020 window that the Suns output is predicted to plummet and sink us into another ice age... Also New data out yesterday PROVES that the ICE SHELF in Greenland NEVER MELTED during the last WARMING PERIOD 100,000 years ago... WHEN IT WAS 9 degrees (F) higher average than today. It is ALL BS!
Greenland was not named because it was ever green but because it pretty much wasn’t and Eric the Red wanted people to go there. So he called it Greenland.
