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 [...]
