There’s a good chance that you’ve been interpreting odds ratios wrong. I know I have. I’ve been interpreting them as if they were risk ratios instead. — Reviewer notes: Odds ratios are really odd
Reviewer notes: Odds ratios are really odd
When psychological researchers investigate binary outcomes, they routinely report odds ratios to quantify the strength of an effect or an association. This is quite understandable given that…

Almost every European plant species is out of equilibrium. Climate change is only part of the story—disturbance greatly shapes where species actually occur. 🚨Our new paper 🌱in @natecoevo.nature.com analysed 3,047 species across >1.1M European vegetation plots. www.nature.com/articles/s41...
I was interviewed by @science.org for this piece on giant trees and drought resilience. An impressive study, but it doesn't overturn previous work: drought responses depend on the forest, the type of drought, and tree traits www.science.org/content/arti...

New study challenges idea that tall trees’ hydraulics make them more vulnerable to dry conditions

NEW: @opb.org and ProPublica found that water from one of Oregon’s most iconic rivers, the Deschutes, is largely given away to wealthy landowners who are turning the high desert green with lush pastures and landscaping.
An Oregon Law Lets One Wealthy Region Turn the Desert Green. When Drought Hits, Farmers Pay the Price.
In the high desert of Central Oregon, the Deschutes River is a lifeline for farmers and landowners — but a century-old water law entitles just a few thousand people to more than half of its volume.

One billion more people face at least one day of extreme heat stress each year compared with the 1970s, says @natclimate.nature.com paper. Findings show global heat stress is intensifying across events during day, night, and during both day and night: spklr.io/63322E3AC8 #ClimateChange 🧪
Global heat stress intensification and its expanding footprint on the human population - Nature Climate Change
The authors assess global changes in heat stress since 1950, considering daytime extremes, nocturnal heat and compound day–night events. They show multidimensional intensification, with an increased frequency of extremes and expanded spatial and temporal footprints of heat stress on humans.
