The Dud PDO Index of Climate Sensitivity
Climate sensitivity is the response of the climate system to a given increment of CO2. It is often expressed as the response to a “doubling” of this gas from a pre industrial level. Estimates of climate sensitivity are all over … Continue reading

The Hawaiian/Emperor Seamounts and How Island Arcs are Formed
Ever wonder why offshore island arcs should form at random spots in the oceans? No? Don’t worry, its a far fig newton. We offer here the suggestion that the locations are not random, that island arc trenches and probably spreading ridges and … Continue reading
The Dim Sum, Microbial Dark Matter and Wine Dark Seas
The oceans are a microbial soup I like to call the Dim Sum. It is an appropriate pun because it is both dim in the sense we don’t understand it, and a dim sum in that we cannot describe it mathematically. The … Continue reading
Charybdis and the Oldest Ocean Floor on Earth
A few years back there was a much ballyhooed drilling effort to find some 175 million year old sea floor touted as the “oldest”. Incorrecto qui mo sabe. That particular ocean floor is interesting in its own right (see our … Continue reading
