Re-evaluating the Concern of Climate Change
By Andy May I’ve just been made aware of a paper critical of the “consensus” view that man-made climate change is dangerous. It is by Ashutosh Sharma, Vinit Vithalrai Shenvi, and Mohit Sain of the MS Ramaiah Institute of Technology in India (or MSRIT) (Sharma et al., 2024). It was published just two months beforeContinue reading “Re-evaluating the Concern of Climate Change”

R Programming tips to process IGRA2 Radiosonde data
By Andy May In the last two posts (here and here) I showed how to read, plot, and map IGRA2 data. In this post I will discuss how to efficiently process large R data frames and lists to compute useful variables. One of the more difficult things to do in R is to write readableContinue reading “R Programming tips to process IGRA2 Radiosonde data”
