2022 Seventh Warmest Year: Warming Slows Down

Guest Post by Javier Vinós reposted from Andy May's Climate Blog No minimally informed person denies that climate changes. The climate has always changed. Since 1860 the predominant climate change has been warming, which is fortunate because if we had a winter like those of 1800-1850, we would be in for a shock. [...]

Ocean currents may be more important than the greenhouse effect

"If it [a scientific hypothesis] disagrees with experiment, it’s WRONG." – Nobel Prize winner Richard Feynman A rather different challenge to the CO2 global warming hypothesis from the challenges discussed in my previous posts postulates that human emissions of CO2 into the atmosphere have only a minimal impact on the earth’s temperature. Instead, it [...]

Meridional Transport, the most fundamental climate variable

By 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 climate.” (Barry, Craig, & Thuburn, 2002) This is the transcript of the talk I gave in [...]

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 [...]
