I started a thread in Great Debates here:
I’m interested to see if anyone actually disputes the graph.
What do you believe the graph is showing out of interest? It does not really relate to “retreating ice at the poles” or Greenland as this thread is about.
I disagree. The graph clearly contains the words “polar ice” in the legend.
Yes, but it’s a meaningless chart without showing where and how that data was collected. Anyone could make up any thing they wanted too and chart it. Or the data could be a collection of meta-data and extrapolation that is cherry picking different data, or using different scales. There is no way to know just by looking at that chart what, if anything, it actually means.
All I want to know is how the conditions today in Greenland differ from those in Greenland during the medieval warming period. I’m trying to get a handle on how MUCH ice has melted both in the polar regions and on Greenland at this point.
As a further question I’d like to know how much of Greenland COULD melt. Half? All? Something else?

All of it could melt, but even in most worst-case scenarios of climate scientists that would take several centuries.
However, Greenland’s current rate of melting is exceeding some of these supposed worst-case scenarios.
Yeah, that’s what I figured. I was watching a show on Discovery about engineering mega eco solutions too the planets problems. One guy had the idea of putting down huge white colored blankets in Greenland to save the glaciers…or at least slow down the melting. He was showing huge new ice lakes out on the glaciers that are highly unstable (I guess a hole can rapidly appear in the lake that drains all the water down to under the glacier, causing it to move more rapidly or to even fracture suddenly :eek:).
The show got me to thinking…how much ice has already melted and how much land that was currently buried is now exposed. And is it more exposed today than it was during the Viking period? Is it warmer there now than it was then? Which was why I started this thread…to find the answers.

I agree. Let’s not turn this thread into a general debate about global warming.
