This site is a reference point for those with a cool head for climate science, arguably the most political science ever. When the government and most of the media concentrate on alarmism, this site is the antidote for those who don't believe the scare stories - YOU ARE NOT ALONE!

MEDIEVAL WARM PERIOD
Anyone who is a denier of the existence of the medieval warm period should read all the evidence at the following link:
No tricks Zone? Not a science contributor. I used to spend time in there talking to them. SKS has two different representations of temperature world wide. Its very clear we are warmer today than during the medieval period. Compare figure 1 to figure 3 and it is a very clear difference between the two showing today's temperatures to be much warmer.
The Medieval Warm Period spanned 950 to 1250 AD and corresponded with warmer temperatures in certain regions. During this time, ice-free seas allowed the Vikings to colonize Greenland. North America experienced prolonged droughts. So just how hot was the Medieval Warm Period? Was it warmer than now? A new paper Global Signatures and Dynamical Origins of the Little Ice Age and Medieval Climate Anomaly (Mann et al 2009) (see here for press release) addresses this question, focusing on regional temperature change during the Medieval Warm Period and Little Ice Age.

Figure 3: Surface temperature anomaly for period 1999 to 2008. Temperature anomalies are defined relative to the 1961– 1990 reference period mean. Gray areas indicates regions where adequate temperature data are unavailable (NASA GISS)
