By Nic Lewis The editors of Nature have retracted the Resplandy et al. paper. Readers may recall that last autumn I wrote several article critiquing the Resplandy et al. (2018) ocean heat uptake study in Nature, which was...

By Nic Lewis There have been further interesting developments in this story Introduction The Resplandy et al. (2018) ocean heat uptake study (henceforth Resplandy18) is based on measured changes in the O2/N2 ratio (δO2/N2)...

By Nic Lewis Introduction The Resplandy et al. (2018) ocean heat uptake study (henceforth Resplandy18) is based on measured changes in the O2/N2 ratio of air sampled each year, compared to air stored in high pressure tanks...

by Nic Lewis Obviously doubtful claims about new research regarding ocean content reveal how unquestioning Nature, climate scientists and the MSM are. On November 1st there was extensive coverage in the mainstream media[i]...

by Tony Brown This article examines the continued cooling of CET this century Looks at a similar scenario of regional cooling in America Examines CET related urbanisation issues, and the current Met office allowances for...

by Judith Curry Part IV of the Climate Etc. series on sea level rise focuses on sea level rise in the satellite era (since 1993), including the recent causes of sea level variations and arguments regarding the acceleration...

By Judith Curry “We are in the uncomfortable position of extrapolating into the next century without understanding the last.” – Walter Munk  Part II provided an overview of the relatively recent geological evidence...

by Javier A possible mechanism for the effect of solar variability on climate, whereby solar variability acts over the stratospheric pressure system transmitting the changes top-down, and over ocean temperatures bottom-up...

by Javier In Part A, we established the existence of a ~ 2400-year climate cycle, discovered in 1968 by Roger Bray. This climate cycle correlates in period and phase with a ~ 2400-year cycle in the production of cosmogenic...

By Javier The existence of a ~ 2400-year climate cycle, discovered in 1968 by Roger Bray, is supported by abundant evidence from vegetation changes, glacier re-advances, atmospheric changes reflected in alterations in wind...

by Javier The Neoglacial has been a period of progressive cooling, increasing aridity, and advancing glaciers, culminating in the Little Ice Age. The main Holocene climatic cycle of ~ 2400 years delimits periods of more stable...

by Javier Vinos First in a two part series on Holocene climate variability. Summary: Holocene climate is characterized by two initial millennia of fast warming followed by four millennia of higher temperatures and humidity,...
