Individual Liberty — Individual Responsibility

For those we lost, We will not forget 09/11/2001

“Our God given unalienable rights are given to us all as individuals. They tell us what we may do for ourselves, and they are the embodiment of liberty. The so-called rights that government gives to some of us are parcelled out to select groups as classes. They tell us what one class of people may require another to do for them, and they are the very essence of slavery.”

Hockey Stick? More Like a Roller Coaster

Global warming enthusiasts like to point out Mann et al's "Hockey Stick" graph of the IPCC temperature reconstruction for the past 1000 years as "proof" that global warming is anthropogenic in nature. There have been lots of criticisms of this graph, including some that point out the flawed statistical methods used to create it. Two major problems with the hockey stick are that it doesn't account for the medieval warm period, or the "little ice age".

Now there's a new study out in Quaternary Research that provides a fairly good reconstruction of the temperature trend for the past 800 years. This study is based on sediment cores taken from Lake Tsuolbmajavri in Finland. By analyzing the types of diatoms that were growing in the lake and laid down in the sediments they come up with a completely different picture. You can read more about this at World Climate Report, the web’s longest-running climate change blog.

Here's a picture of the roller coaster. What's interesting is that it's actually cooler now than it was in the late 1400s...
