A reader writes in: I think Steve and the other CA readers will be interested in the new article by Matthew Salzer and Malcolm Hughes (of MBH fame) entitled “Bristlecone pine tree rings and volcanic eruptions over the last 5000 yr” in the latest issue of Quaternary Research, “> available for free. I don’t have […]
We hear lots about polar amplification. Mears and Wentz recently updated their TMT (mid-troposphere) data for 60-70S, but didn’t update the more controversial TLT3 (lower-troposphere) data, which is current only to August 2006. Given the pending IPCC 4AR, you’d think that Mears and Wentz would be completely up-to-date with their lower troposphere results. Is there […]
On January 1, in a post entitled Two Curious Hurricane Graphs, I observed that the mean longitude of Atlantic storm measurements had migrated east and that the entire increase in Atlantic storm-days had occurred in the east Atlantic, illustrating the point with several graphics. To my knowledge, neither fact had ever been previously published. I […]
The Toronto Star has broken the embargo on the IPCC AR4. They give a short synopsis of the expected from the Summary for Policy Makers. One of the items in the short review was the relative attribution between solar and greenhouse. The article says: Rebutting one of the main arguments of climate change skeptics, it […]
I just noticed an excellent comment by Sonechkin (one of the Moberg authors) on the CPD submission of Bürger and Cubasch. I suspect that climateaudit readers will agree with everything that he says. The remarkable thing is that these claims, which we’ve been making for some time, should ever have been controversial.
A new thread at bender’s suggestion. Treelines are a climate indicator that I’ve paid attention to in the past as evidence that made sense to me about the relationship of modern and medieval climate. I’ve posted up threads in the past about tree lines in California being higher than at present in the MWP and […]
Roger Pielke pointed out that Holland and Webster have presented a PPT presentation posted up at UCAR (the home of IPCC WG1), the content of which is relevant to recent discussions at climateaudit and prometheus. The entire presentation is about data problems relating to storm trends in the eastern Atlantic and to landfall hurricanes, topics […]
Opinions expressed on Climate Audit, other than those expressed by Stephen McIntyre personally, are those of the individual posters and do not necessarily reflect the opinions of Climate Audit or myself.
One of the common operations in the types of analyses done here is simply counting things. I am constantly amazed by the tremendous productivity of the tapply function in R – I use it over and over – for producing interesting results at warp speed. There’s nothing particularly novel in how I use it, but […]
