@Wetrix If you read again carefully you'll see the key part: MWP was *regional* phenomenon. Current AGW is a *global* phenomenon, which has much larger impact on the *whole* planet.
The bluish shows MWP average temperatures difference vs 20th century and you can clearly see that it was warmer in *some* places but globally it was actually colder than today.
The redish picture shows temperature difference 20th century vs today.
Can you spot the difference?
