by Nicola Scafetta Two publications examining the equilibrium climate sensitivity (ECS) have recently been published in Climate Dynamics: Scafetta, N. (2022a). CMIP6 GCM ensemble members versus global surface temperatures. Lewis, N. (2022). Objectively combining climate sensitivity evidence.

by Alan Longhurst The pattern of warming of surface air temperature recorded by the instrumental data is accepted almost without question by the science community as being the consequence of the progressive and global contamination of the atmosphere by CO2.   … Continue reading →

by Javier Vinós & Andy May “The atmospheric heat transport on Earth from the Equator to the poles is largely carried out by the mid-latitude storms. However, there is no satisfactory theory to describe this fundamental feature of the Earth’s … Continue reading →

by Dan Hughes I recently ran across the paper by Isenko et al. [2005] listed below. The second paragraph of the introduction states: “According to the conservation of energy, the loss of potential energy for a volume of water is sufficient to … Continue reading →

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (II). Solar activity unexplained/ignored effects on climate by Javier Vinós & Andy May “The complicated pattern of sun-weather relationships undoubtedly needs much further clarification, but progress in this field will be hindered if … Continue reading →

by Judith Curry The loss of glaciers from Glacier National Park is one of the most visible manifestations of climate change in the U.S.  Signs were posted all around the park, proclaiming that the glaciers would be gone by 2020.  … Continue reading →

by Javier Vinós & Andy May “On the other hand, I think I can safely say that nobody understands climate change.” J. Vinós, paraphrasing Richard Feynman’s words about quantum mechanics.

by Dan Hughes The contribution of viscous dissipation conversion of kinetic energy into thermal energy has been significantly over-estimated in three recent publications. The kinetic energy content of the macro-scale mean flow is assigned to be the heat dissipation into … Continue reading →

by Judith Curry “The first rule of climate chess is this.  The board is bigger than we think, and includes more than fossil fuels.”  – Jon Foley

by Thomas Anderl Simple models are formulated to identify the essentials of the natural climate variabilities, concentrating on the readily observable and simplest description. The results will be presented in a series of five articles. This first part shows an … Continue reading →

By Nic Lewis This article concerns the paper “Globally resolved surface temperatures since the Last Glacial Maximum” by Matthew Osman et al.[2]  (hereafter Osman 2021) published by Nature in November 2021.

by Judith Curry Heat waves are the new polar bears, stoking alarm about climate change.  Climate scientists addressing this in the media are using misleading and/or inadequate approaches.  How should we approach assessing whether and how much manmade global warming … Continue reading →

by Javier Vinós & Andy May “Once you start doubting, just like you’re supposed to doubt. You ask me if the science is true and we say ‘No, no, we don’t know what’s true, we’re trying to find out, everything … Continue reading →

by Javier Vinós & Andy May “No philosopher has been able with his own strength to lift this veil stretched by nature over all the first principles of things. Men argue, nature acts.” Voltaire (1764)

by Planning Engineer The “green” provisions of the poorly named  Inflation Reduction Act  are sweeping and it appears they may do more harm than good. The philosophy behind the inflation Reduction Act seems to reflect the belief that if you … Continue reading →

by Javier Vinós & Andy May “These shifts are associated with significant changes in global temperature trend and in ENSO variability. The latest such event is known as the great climate shift of the 1970s.” Anastasios A. Tsonis, Kyle Swanson … Continue reading →

by Javier Vinós and Andy May “Probably no subfield of meteorology has had as much effort devoted to it as the effects of solar variability on weather and climate. And none has had as little to show for the research … Continue reading →

by Judith Curry A few things that caught my eye these past weeks

by Ross McKitrick Two new peer-reviewed papers from independent teams confirm that climate models overstate atmospheric warming and the problem has gotten worse over time, not better. The papers are Mitchell et al. (2020) “The vertical profile of recent tropical … Continue reading →

by Judith Curry There is a growing realisation that emissions and temperature targets are now detached from the issues of human well-being and the development of our 21st century world.

by Judith Curry “The field of Sun-climate relations . . . in recent years has been corrupted by unwelcome political and financial influence as climate change sceptics have seized upon putative solar effects as an excuse for inaction on anthropogenic … Continue reading →

by Dan Hughes A brief continuation of previous discussions about calculation of viscous heat dissipation in the flow of liquids having linear stress/rate-of-strain constitutive description.
