What about it? Globally, it's warmer now than then. Despite the fact that the sun has been quieter for the past 35 years or so, and TSI has been lower.

So why don't you tell us about the so called "medieval warm period" and what caused it?

Very hard to determine if the MWP was slightly warmer or cooler than today. First off, we would be comparing proxy data to satellite/thermometer readings. Second, the difference would be just a couple tenths of a degree either way from today. Also, the MWP lasted for 300 years. Current warming started at the end of the Little Ice Age around 1850.


As for the causes, low volcanic activity, and more solar activity is said to be responsible for the MWP. Looks as if sun spot activity was less between 950-1250 when compared with this past century

Until recently it was thought that only particularly large eruptions had any noticeable affect on the climate.



Volcanoes ARE cooling Earth and have reduced temperatures and tropical rainfall | Daily Mail Online
And yet the temperature is the highest in recorded history. I guess AGW is for real.

AGW? No.

But the earth does heat and cool periodically.

no man is not '''driving'' it...the effect man has is 10% or less...and that is where the '''man-made'' LIE comes from


in order for it to be man-made/man-caused, mans play would HAVE TO BE a major majority...a 10% effect is not

Since the Earth would be about 0 degrees without a greenhouse effect, a 10% change would be pretty bad.
