Union of Concerned Scientists Issues False, Misleading Report
A few simple questions to ask liberal 'friends' about Global Warming:
*Why is Greenland named Greenland?
*What was the Medieval Warm Period?
*What was the solar activity during that period?
*What is the solar activity (brightness) today?
For those not familiar, here is a Wiki link to get you started
From the article you cited:
"It is said that Erik the Red was exiled from Iceland for murder. He, along with his extended family and thralls, set out in ships to find the land that was rumored to be to the northwest. After settling there, he named the land Grænland ("Greenland"), possibly in order to attract more people to settle there. Greenland was also called Gruntland ("Ground-land") on early maps. Whether Green is an erroneous transcription of Grunt ("Ground"), which refers to shallow bays, or vice versa, is not known. It should also be noted, however, that the southern portion of Greenland (not covered by glacier) is indeed very green in the summer."
What was the Medieval Warm Period?
A period of warmer climate preceding the Little Ice Age.
What was the solar activity during that period?
Judging from data that can be gathered, about the same as today.
