We all know that we are in the warm period of cyclical ice ages (macro climate changes).
But let's look at the last "millennial time scale", a micro cycle, shall we?

In 950AD a warming period reversed the colder global temperatures. This warming period (called the Medieval Warm) lasted about 300 years (950AD-1250AD). This was the time period when wine grapes famously grew in England.

Then it began to get cold, really cold, so cold that scientists call this period the Little Ice Age. Life became hard! The cold lasted about 570 years (1250AD-1820AD).

Then thank the Good Lord it began to get warm again. Life became easier. The Modern Warm Period has lasted from 1820AD-Present, about 200 years.

So in the last millennia we have gone from cold to hot, back to cold, and hot again! And losh, this just forces me to ask you some questions since you appear to be both knowledgeable on the subject and an advocate that is not afraid to engage in an intelligent conversation.

While I am directing these questions to losh, please if you have the answer please jump in!

1) What is the normal or base temperature of the Earth in the last 1000 years?
2) What did humans do in 950AD to warm up the whole planet? The Vikings were starting to pillage, plunder, rape, murder, and burn. But they didn't burn that much!?
3) What did humanity do to restore the cold?
4) Did the people of 1250AD over correct the warming, or are the conditions of the Little Ice Age normal and/or desirable?
5) The amount of CO2 produced at the birth of the Industrial Revolution were minuscule. How did the people of 1820 put enough CO2 in the atmosphere to reverse the hard cold?
