Resolution and Hockey Sticks, Part Deux: Carbon Dioxide

Guest geological perspective by David Middleton In Part 1 of this series on resolution in signal processing, we discussed the integration of high resolution instrumental temperature records and lower resolution paleoclimate proxy data in climate reconstructions. In Part Deux, we will look at the integration of high resolution instrumental carbon dioxide records and lower resolution…

Mann used the 20-year anniversary of the graph to opine on the “industry-funded” attacks “to discredit the iconic symbol of the human impact on our climate,” which Mann claimed…

Steve McIntyre discovers another hockey stick

Steve McIntyre the Canadian mining engineer and math wizard who discovered why Michael E. Mann’s original hockey stick of global temperature data was made of bunkum wood, has now discovered yet another one, and it appears not to use adjusted data, but raw data. This one also indicates temperature, but of a different kind. It…
