How Gaia and coral reefs regulate ocean pH

by Jim Steele

Although some researchers have raised concerns about possible negative effects of rising CO2 on ocean surface pH, there are several lines of evidence demonstrating marine ecosystems are far more sensitive to fluxes of carbon dioxide from ocean depths and the biosphere’s response than from invasions of atmospheric CO2. There is also ample evidence that lower pH does not inhibit photosynthesis or lower ocean productivity (Mackey 2015). On the contrary, rising CO2 makes photosynthesis less costly.

Sea level rise, acceleration and the closure problem

by Rud Istvan

There is no doubt that interglacials change sea level (SL). And that sea level rise (SLR) can be dramatic on millennial interglacial time scales.

Science into agitprop: “Climate Change is Strangling Our Oceans”

by Larry Kummer, from the Fabius Maximus website

The public policy debate about climate science shows the dysfunctional nature of the US media. Here’s another example of how propaganda has contaminated the news reporting of this vital subject, looking at stories about a new study of our oceans.

ENSO and the anchovy

by phlogiston a.k.a Phil Salmon

If one wishes to gain a “heads-up” as to imminent developments in ENSO and possible beginnings of an el Nino or La Nina event, I would advise turning to the Peruvian anchovy as an important but often overlooked oracle to the oceanography of the anchovy’s home ocean, the Pacific.
