If interested in precipitation efficiency and climate sensitivity, here is a review paper that has been in press for 18 months (!), expected publication mid-2023. Yay AGU Monographs... essoar.org/doi/abs/10.100…

Tim Raupach, Joshua Soderholm, Alain Protat, and Steven Sherwood developed an improved method to estimate when given atmospheric conditions are prone to producing hail in Australia, which is useful when direct hail observations are not available. journals.ametsoc.org/view/journals/…

Urban "heat island" effect on temperature well known, but there is a systematic increase in moist-heat measures, even wet-bulb temperature which most heavily weights humidity: nature.com/articles/s4158…

Two pieces in Nature today: 1) Ben Sanderson pointing out scientists should be limiting travel and CO2 emissions. 2) New research showing giving talks in person helps one's career. A dilemma.

Surprisingly large local hail trends can be predicted using new hail proxy; Sydney (and Perth) hail frequency has increased by 40% since 1980's, but not elsewhere in Australia.

Two new studies calculate that humid heat extremes will begin to breach a human tolerance limit much more frequently if world passes 2C. In that case, expect climate refugees from the most humid places. pnas.org/doi/10.1073/pn… science.org/doi/10.1126/sc…

I'm glad someone's noticed ... Australia’s research sector chases rankings over quality and is ‘not fit for purpose’, chief scientist says theguardian.com/australia-news…

Unresolved processes in atmosphere models have inherent persistence or 'memory,' which these models treat incorrectly or (usually) not at all: agupubs.onlinelibrary.wiley.com/doi/10.1029/20…

Misinformation on human contribution to the greenhouse effect continues, so here is a table of estimates (these quantities not easy to find in e.g. IPCC, since not the way we normally quantify things). For comparison, 1K warming is 3% of the natural 33K effect.

This fabric with spectrally selective IR emissivity is really (literally) cool! But I wonder whether there is a net cooling from from wearing it given that it will inhibit perspiration cooling: sciencemagazinedigital.org/sciencemagazin…
