Oxygen-18 Stability in Foraminifera fossils, implications in paleoclimatology

By Andy May 18O is a rare isotope of oxygen. The ratio of 18O to the normal 16O in foraminifera fossils (“forams”) can be used to estimate paleo-ocean temperatures. Higher values mean lower temperatures. A recent article on geologypage.com (here) led me to Bernard, et al., 2017, which has experimental data that suggest 18O concentrationsContinue reading “Oxygen-18 Stability in Foraminifera fossils, implications in paleoclimatology”

The Effects of the Bray Climate and Solar Cycle

By Andy May Javier has posted three new essays on the Bray climate and solar cycle on Judith Curry’s web site. Part A is here, part B is here and Part C is here. In these posts, he lays out the evidence, in some detail, for the climate cycle and the associated solar cycle. HereContinue reading “The Effects of the Bray Climate and Solar Cycle”
