Yes before the 1400's the earth was warmer than it currently is. The world was still coming down from the high temps.
Then the abberation of the LIA occured. and it bounced back, and kept going down until the IR.
lets do this, This is a generic graph to show what I'm talking about.
AA....BB....CC....DD....EE....FF....GG...HH....II....JJ....KK....LL....MM
58....56....55....52.....44....40....39....44....51...50....49....51....53
At points AA through DD normal global cooling is occuring. Then at point EE we started the LIA. Abnormally rapid cooling occured. The cause was unusually high volcanic activity. Around point HH the planet recovers and by II we are back to normal global cooling levels.
Then point LL (slightly after the Industrial Revolution) and there is a change in direction. The planet starts warming and as you go out to and pass point MM the planet keeps warming when it really should continue to cool to 48...47... etc.
So when you average out the LIA anomaly you see the graphs steady decline. We know the cause for the LIA. We also know the cause for the STRONG warming trend we are experiencing now.
And it is a strong trend. This is the most rapid warming this planet has experienced for at least 4 million years and possible the fastest warming in the last 20 million.
