I made my very own climate hockey stick.

I am an aspiring climate scientist, and as such I thought I might learn from the most famous climate scientist in the world.  Michael Mann. Professor Mann’s methodology seemed pretty straight forward. Take tree ring data as a proxy for temperatures over thousands of years and add the measured temperatures on to the end. Simple!

It just so happens some very nice people here in Australia did a tree ring temperature reconstruction that I could use.  Awesome!

Some Huon Pine trees from Mount Read in Tasmania were used for the tree ring data. Mount Read also has a weather recording station so the data should match up pretty well.

So here it is, but it looks a little different from Professor Mann’s graph. Did I do something wrong?

Please note:  All data is real (except for the years 1992 to 1996. No data available, so just joined the “dots”). Months used were November to April. “The warm months”.
