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 concentrations can be altered in fossils by solid-state diffusion after fossilization. This can corrupt the measurement and the resulting calculated temperature

When it comes to climate change, there are worlds apart between Germany’s aspiring Jamaica Coalition partners. It is all about coal and it is not certain the divide can be bridged.

Under the U.S. Global Change Research Act of 1990, the federal government has been charged with producing large National Climate Assessments (NCA), and today the most recent iteration has arrived. It is typical of these sorts of documents–much about how the future of mankind is doomed to suffer through increasingly erratic weather and other tribulations. It’s also missing a few tidbits of information that convincingly argue that everything in it with regard to upcoming 21st century climate needs to be taken with a mountain of salt.

European mean sea-level records are among the best time series data available globally by which to detect the presence of necessary accelerations forecast by physics-based projection models to elevate current rates of global sea-level rise (≈3 mm/y) to anywhere in the vicinity of 10–20 mm/y by 2100. The analysis in this paper is based on a recently developed analytical package titled “msltrend,” specifically designed to enhance estimates of trend, real-time velocity, and acceleration in the relative mean sea-level signal derived from long annual average ocean water level time series

Biases in climate model simulations introduce biases in subsequent impact simulations. Therefore, bias correction methods are operationally used to post-process regional climate projections. However, many problems have been identified, and some researchers question the very basis of the approach.

(…)Key findings are that at the 95% confidence level, no consistent or compelling evidence (yet) exists that recent rates of rise are higher or abnormal in the context of the historical records available across Europe, nor is there any evidence that geocentric rates of rise are above the global average. It is likely a further 20 years of data will distinguish whether recent increases are evidence of the onset of climate change–induced acceleration.

In January 1972, the National Science Foundation held a meeting at Brown University to discuss “climatic change” – then meant global cooling, which they said was of natural origin.

This month two major North Sea storms have hit Europe rather severely, and not surprisingly the usual climate ambulance chasers were out in force to try to pin the blame on man’s activity, and in doing so ignored the climate history that provides us with the proper perspective. We look at some analyses of past German storm activity.

Les scientifiques en déduisent que le réchauffement global actuel pourrait potentiellement être “sans précédent” sur les 100 derniers millions d’années. L’étude de ces géochimistes, publiée dans Nature Communications, constitue une sorte de pavé dans la mare des paléoclimatologues qui utilisent depuis les années 1950 ce “paléothermomètre” aidant à bâtir les modèles actuels sur le réchauffement climatique
