Loehle and Moberg

Julien Emile-Geay has made many forceful criticisms of the Loehle reconstruction. For example, he says: Relationship of each proxy to *local* temperature is not even discussed. We are just shoved a list of references (hey Craig , have you heard of tables ? They are a great means that scientists use to convey information clearly). […]

Sampling from Contaminated Distributions

"Standardization" and averaging are operations that are done time after time in paleoclimate studies without much discussion of the underlying distributions. If one browses through recent statistical literature on "robust statistics", one finds much sophisticated analysis of how to handle outliers. The term "robust" is commonly used in paleoclimate, but the term as used in […]

Treydte, Moberg, Soon and Baliunas

Several people have written to me about today’s article in Nature by Treydte et al (including Esper) announcing that the 20th century is the wettest period in the millennium. Treydte et al state: Comparison with other long-term precipitation reconstructions indicates a large-scale intensification of the hydrological cycle coincident with the onset of industrialization and global […]

Mo' Mo' Moberg

Many of you read Moberg. Some of you probably saw the following diagram showing the re-combination from wavelets to yield the final reconstruction. It looks like an even more complicated method than MBH98 – "science moves on". Moberg Figure 2. So if I offered to show you plots of the wavelet decompositions of all 11 […]
