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…
Some Failed Climate Predictions
By Javier Here, for the first time in public, is Javier’s entire collection of massive, “consensus” climate science prediction failures. This collection is carefully selected from only academics or high-ranking…
The Atmospheric Lapse Rate and Molar Density
By Andy May, Michael Connolly and Ronan Connolly In this post, we will discuss the tropopause, atmospheric molar density and the lapse rate (the change in atmospheric temperature with altitude).…
Al Gore’s Apocalyptic Fantasy Lecture at Rice University
As promised, I attended Al Gore’s climate change lecture at Rice University last night. Rice University is one of the most beautiful university campuses I’ve ever seen, so it was…
Preparing for Al Gore’s Lecture at Rice University
By Andy May I have a ticket to Al Gore’s global warming lecture at Rice University on October 23 and plan to attend, I’m very curious about what he will…
University of Chicago Air Quality-Life Index
By Andy May The University of Chicago Energy Policy Institute has come up with a new measure of air pollution they call the Air Quality-Life Index or AQLI. It uses…
Arctic Ice Natural Variability
By Javier A year ago I wrote an article at WUWT analyzing the recent upward trend in summer Arctic sea ice extent. Despite challenges of statistical irrelevancy, the trend has…
Coral Reefs, Temperature and Ocean pH
By Andy May Georgiou, et al. 2015 have reported that coral reefs in the Australian Great Barrier Reef, near Heron Island, are insensitive to ocean pH changes. The location of…
Climate Model Projections Significantly Diverge from Paleoclimate Analogs
By Renee Hannon Introduction Over the past million years, our Earth displays a rhythmic beat when exiting full glacial cycles and entering interglacial warm periods. The characteristics and duration of…
HADCRU Power and Temperature
By Andy May Generally, it is agreed that the Earth’s top-of-atmosphere (TOA) energy budget balances to within the margin of error of the estimates (see Kiehl and Trenberth, 1997). The…
Comments on the Connolly’s Atmospheric Physics Papers
My links to comments did not survive, so I added more information to help find the original comments in the original post. The following comments are from Dr. Ronan Connolly…
Review and Summary of three Important Atmospheric Physics Papers
by Andy May Introduction In 2014, Dr. Michael Connolly and Dr. Ronan Connolly posted three important, non-peer reviewed papers on atmospheric physics on their web site. These papers can be…
Oceanic Downwelling and our Low Surface Temperatures
Guest Post by Wim Röst Introduction The creation of ‘Hot Worlds’ and ‘Glacial Worlds’ during past geological periods was only made possible by warm and cold deep oceans, respectively, that…
A Deterministic Forecast of Future Climate Changes
By Renee Hannon Introduction In my previous WUWT post, I proposed a conceptual process model describing the influences of astronomical controls on interglacial warm periods and glacial cycles (Figure 1).…
Cooling Deep Oceans – and the Earth’s General Background Temperature
Guest Post by Wim Röst Introduction Five million years ago, average temperatures were higher than they are now. During the Pliocene, the era just before the period of the Quaternary…
Arctic melt season changes and the Arctic regime shift
By Javier In sharp contrast with previous decades, the past 10 years have seen no change in Northern Hemisphere average sea ice extent, according to MASIE (may-zee, Multi-sensor Analyzed Sea…
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…
Paleoclimate Cycles are Key Analogs for Present Day (Holocene) Warm Period
Guest Post By Renee Hannon Abstract Detailed pattern correlation of Earth’s temperature changes during the past 450 kyrs reveals observations about several cyclic climate patterns. The past four glacial cycles…
Warm is stable – Cold is change
Guest Post by Wim Röst Introduction Today ‘warm’ is strongly connected with ‘climate change’, if not with ‘dangerous climate change’. In the minds of people ‘cold’ should be more stable.…
