Climate Change Global Warming Science Rules The Data

And Now For Some Zen…

Michael Mann and his colleagues published a paper back in 2008 with the title “Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia”, which demonstrated reliably that very recent global temperatures are higher than for thousands of years, and that the rate of warming is unprecedented in a similar timeframe :-

This paper confirmed the previous “Hockey Stick” analysis.

Towards the end of the paper, comes this :-

“…Conclusions are less definitive for the SH [Southern Hemisphere] and [hence the] globe, which we attribute to larger uncertainties arising from the sparser available proxy data in the SH. Given the uncertainties, the SH and global reconstructions are compatible with the possibility of warmth similar to the most recent decade during brief intervals of the past 1,500 years. A targeted effort to recover additional high-quality, long paleoclimate proxy records from the SH could reduce these current existing uncertainties…”

The need for temperature proxy information in the Southern Hemisphere…That set me thinking…
