>> Now its not common/normal for global climatic changes to reverse themselves in less than 100 years.

Have you ever heard of a "local maximum" or "local minimum?" These terms are familiar to anyone who ever studied Calculus. These are the points on a curve when the current trend "reverses" itself (e.g., the point at which the line tangent to the curve has a slope of zero).

As you can see from the graph below, it happens ALL THE TIME. That graph represents a very brief period in the Earth's history, and has at least 30 fairly significant such reversals, an average more than one every hundred years.

Two other points:

1) You will also notice the MWP had temperatures roughly where we now are; and

2) Even with all this considered the variability in temperature over 2000 years has a range of about 1.0C. One degree, top to bottom, is what we're talking about.

Get your breath. The sky isn't falling.
