Pulsating Alpine glaciers

The Alpine glaciers are shrinking, that much we know. But new research suggests that in the time of the Roman Empire, they were smaller than today. And 7,000 years ago they probably weren’t around at all. A group of climatologists have come up with a controversial new theory on how the Alps must have looked over the ages.

This is more of what I believe.   Some scientists have taken a very short period of time and pretty much ignored the rest of the story.  I want to know the entire picture before we try to make drastic changes that could be more harmful than good.
