New paper alert! 🚨 Incredibly, the western Arctic was warmer in 2023-24 than 1998 during what, at the time, was considered a truly remarkable climatic event. Permafrost is responding in turn. Wonder what the super El Nino will bring this year 🫪 cdnsciencepub.com/doi/10.1139/...

New study suggests that raising school ventilation levels to ASHRAE 241 targets could reduce flu cases by 33% for the WHOLE POPULATION! We need clean air in schools so bad!!! www.medrxiv.org/content/10.6...
Climate-Ready Buildings: Insights from U.S. Schools in a Global Context

Climate Week NYC • Sept 23
Projected Health Impacts of Cleaner Air in NYC Schools 
Geetha Jeyapragasan and Charlie Whittaker I University of California, Berkeley
We modelled the projected impact of higher levels of ventilation and filtration in NYC schools. We did this by assessing the impact of achieving a field-recognized standard for healthy indoor air (ASHRAE Standard 241), developed by the American Society for Heating, Refrigeration and Air Conditioning, the professional association of ventilation engineers. Adopting it in schools would reduce the burden of seasonal respiratory illness and improve preparedness for future epidemics.
We developed an epidemiological modelling framework to estimate how improving building air quality affects airborne disease transmission in schools. Here, using seasonal influenza as a case study, we share results about the potential public health impact of raising ventilation such that all schools met ASHRAE 241 targets, approximately 9 equivalent air changes per hour (ACH).
INFLUENZA INFECTIONS AVERTED
PER YEAR
54%
IN CHILDREN
33%
IN OVERALL POPULATION
Share of influenza infections averted in children and the general population if all schools achieved ASHRAE 241 filtration targets. This also results in 30% reduction in hospitalizations across all ages.

SAVED
Days of school absenteeism prevented each year through reduced influenza transmission, and the value of the parental working time no longer lost to caring for sick children.

Why This Matters for New York City
ALL FLU CASES
New York City operates the largest public school system in the United States, with approximately 880,000 students across 1,800 schools. A large portion of this infrastructure predates modern ventilation standards, with the average school building around 70 years old. An inspection of NYC schools i…

Two amazing loess sections in Nebraska. Left, Middle to Late Pleistocene loess in a canal cut near Elba. Note gullies formed in the Late Pleistocene, then buried by loess. Right, Moran Canyon cut exposing the Brady Soil, formed at the Pleistocene-Holocene transition, halfway up by the cedar.
A large, high cut made for an irrigation canal. Layers of loess (wind-blown dust) are exposed, along with soils formed in them. One soil is dark brown, others are reddish brown. There are ancient gullies eroded into loess and then buried by more loess.Loess exposed in a road cut, most of which is very light grayish to yellowish brown. There is a darker gray buried soil half way up the cut, several meters below the ground surface at the top.
