Some comments here refer to a "tolerance" aspect of psilocybin. It might be more clearly termed 'refractory period'. Stan Grof from his clinical work would time LSD sessions no closer together than 1 week and that short period was unusual, usually with OCD patients. I have a friend with moderate OCD, has dosed several times on psychedelics and never gotten an effect.

Shannon's original paper on the topic was written during WWII and I believe it was classified and is much more concise as an introduction. After that, he and Weaver put together the famous and much more comprehensive 1948 paper which expanded into the noisy coding theorem. Meanwhile his original paper ("Communication in the Presence of Noise") was published in 1949, possibly after declassification. I highly recommend reading it first, taking maybe an hour to read. Another terrific intro is a chapter of a book by Bruce Carlson: "Communication Systems: An Introduction to Signals and Noise..." I have a scan of the chapter linked here: https://drive.google.com/file/d/0B9oyGOnmkS7GTFlmQ2F1RWNFd28...

So my question would be, if the paper is logically sound then we are looking at a mechanism where the energy boost from increasing ocean temperatures is only applicable to the storms of cat 5. Why? Because we have data that show the yearly frequency of named tropical cyclones. The chart of these fequencies from 1980~2022 which I link below, indicates no discernable trend. This means that the postulated increase in storm intensity is somehow not promoting otherwise 'would-be' tropical storms into the cyclone categories. Consider the energy distribution over the 5 categories. So this leaves us with, if the logic of the paper is verified, a situation where only the kurtosis of that distribution is affected by ocean temperature -- and not any other statistial parameters. So this should be a future topic for study, why only the higher energy storms are enhanced and not the lower energy ones. In other words why is the kurtosis of this distribution enhanced by increasing ocean temperature? link: https://www.statista.com/statistics/1269915/number-named-sto...

> Without any disrespect intended, anybody, who thinks the ocean is meaningfully rising because of human activity, I'd rather not have living in my town;

Without any disrespect, perhaps you would think differently if you'd had a career in exploration geophysics for mineral resources and energy spanning a few decades as I have had.

I started out with continent wide surveying to peg old pre-GPS maps to WGS84 and have worked on mapping the global magnetic field, the geoid (mean 1G gravity surface), continent wide tidal models and radiometric references, etc.

It's clear enough that human activity is causing more heat energy to be trapped in the lower atmosphere and upper sea levels, the artic and antartic are slowly shrinking back .. and none of this is as yet readily perpectabe to the casual human eye - good instrumentation and records tell a different story, as was peer linked in a comment here.

I have little interest in convincing you, this is just a factual statement of my experience and yourself and your town can continue to believe whatever you collectively choose - it has zero impact on what is actually happening and what the next generations will have to deal with as a result of a century of excessive fossil fuel consumption.

A new generation has come up since Al Gore's fictional movie from 2006, presumably starting production in 2005. I have seen zero evidence of the predicted calamitous events that would distiguish this day from those in 2005. however I have seen the evidence of widespread problems in children who are having nighmares of a future "planetary emergency" which never seems to arrive. If children with emotional problems are the preferred social outcome of this political science, then the science is a success
