When you're living through a hurricane or extreme heat, keeping the lights can be a matter of life or death—but our power grid is woefully unprepared to meet the moment.
How do we get there?

This seems bad. Over time, what people have assumed was the physical limit of human heat tolerance keeps going down. It used to be thought it was a wet-bulb of 35C, now it seems it's more like 32C for resting humans and 27C for people doing minimal physical activity.

Concerned for the future of @noaa.gov, let’s give some love to Ferret - developed by PMEL and every modellers secret go to tool for interrogating / analysing netcdf files. It might not be as ‘a la mode’ as python or Julia, but it gets the job done with minimum fuss 🌊 ferret.pmel.noaa.gov/Ferret/
Data Visualization and Analysis | Science Data Integration Group - Ferret Support
Ferret is an interactive computer visualization and analysis environment designed to meet the needs of oceanographers and meteorologists analyzing large and complex gridded data sets. It runs on recent Unix and Mac systems, using X windows for display. PyFerret, introduced in 2012, is a Python module wrapping Ferret. PyFerret is an upgrade to Ferret which runs existing Ferret scripts and includes all Ferret functionality with updated graphics capabilities and additional analysis functions. In addition the pyferret module provides Python functions so Python users can easily take advantage of Ferret's abilities to retrieve, manipulate, visualize, and save data.

Extreme weather can affect the spread of diseases such as malaria, dengue fever, and cholera. New research explores how these climate patterns can interact with population immunity, affecting disease spread years after the climate event itself.

For the lecture on ocean circulation, I show my students this sea surface temperature simulation from NOAA/GFDL, where scientists were fired recently.

You see the major surface current systems, like the Agulhas current, Brazil current, Gulf Stream, Pacific Equatorial current, and Kuroshio current.

🌊 Why is the North Atlantic Cooling?

A @natureportfolio.bsky.social study uncovers how a cold patch in the North Atlantic - despite global warming - feeds itself by influencing wind patterns.

Could this reshape our understanding of climate change?

For those wanting context, the Atlantic meridional overturning circulation (AMOC) keeps Europe relatively warm compared to places of similar latitude (eg northern Canada). If AMOC shuts down due to climate change the UK would rapidly become 5-15C *colder*. Obviously we are not well prepared for this
