The Winter Gatekeeper Hypothesis (VII). A summary plus Q&A

by Javier Vinós & Andy May reposted from Climate Etc. “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. 7.1 Introduction This plain-language summary has been written at the request of some readers of our series of [...]

New peer reviewed paper: climate sensitivity a third lower (Climate Etc. version)

by Nic Lewis reposted from Climate Etc. Official estimates of future global warming may be overstated. A brief summary in press release style of my new paper (written in the third person) One of the most important conclusions of the recent 6th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR6) was [...]

Models versus global surface temperatures: ECS discussion

by Nicola Scafetta reposted from Climate Etc. 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. These two papers are significant because they take different but complimentary approaches and achieve the same [...]

How the Greenland ice sheet ‘really’ fared this year

The Greenland ice sheet’s melt season is over, bringing the 2021-2022 season to a close. Below I take a deep-dive into how the poster boy for global warming fared over the past 12-months. ‘SURFACE’ MASS BALANCE Greenland’s ice sheet gains snow and ice from September through to the following June, and then, as [...]

New peer reviewed paper: climate sensitivity a third lower

Official IPCC estimates of future global warming may be overstated Press Release by GWPF A new paper reduces the estimate of climate sensitivity – the amount of warming expected for a doubling of carbon dioxide concentrations – by one third. The results therefore suggest that future global warming will be much [...]

A Much Larger Greenhouse Effect – But Temperatures Dominated by Cooling

Guest post by Wim Röst Foreword Especially for Policymakers The greenhouse effect appears to be much higher than previously assumed. However, that also means that the greenhouse effect does not determine the temperature. Earth's temperatures are way lower. The level of Earth's temperatures appears to be completely dependent on cooling by the [...]

The Greenhouse Effect, Revisited

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." Nobel Prize winner Richard Feynman As a further addendum to my series of posts in 2020 and 2021 on the CO2 global warming hypothesis, this post presents another challenge to the hypothesis central to the belief that humans make a substantial contribution to [...]

Simpletons versus wicked scientists

by Judith Curry - Reposted from Climate Etc. In which wicked scientists are the good guys. Activism by climate scientists has been the topic of numerous prior blog posts at Climate Etc.  Such activism is generally focused on eliminating fossil fuels.  This post presents a new framing for the activism issue. While [...]

The Sun-Climate Effect: The Winter Gatekeeper Hypothesis (VI). Meridional transport is the main climate change driver

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) 6.1 Introduction Climate is a thermodynamic process determined by the energy flux from its entry point, mostly [...]

Clintel Declaration Collapses Climate Consensus – says Friends of Science Society

The CLINTEL World Climate Declaration that there is no climate emergency and we do have time has more than 1200 science and scholarly signatories, and thus collapses the climate catastrophe ‘consensus’ narrative, says Friends of Science Society. Likewise, since there is no emergency, society must abandon NetZero targets and ramp up conventional, reliable energy [...]
