Previously, I posted that Na-ion batteries were likely to reach Li-ion battery energy density faster due to the prior advances and experience from Lithium work. Well, that’s appears to be the case. 🧪🔌💡☀️💨💧🔋 www.uh.edu/news-events/...
Breakthrough New Material Brings Affordable, Sustainable Future Within Grasp
Researchers have developed a new material for sodium-ion batteries, sodium vanadium phosphate, that delivers higher voltage and greater energy capacity than previous sodium-based materials. This break...

This year's Arctic Report Card from the National Oceanic and Atmospheric Administration finds that the northernmost part of the Earth is warming faster than the global average, leading to melting glaciers, shifting fish populations, and rivers running orange. n.pr/4rYZwLP
New report finds the Arctic continues to warm faster than the planet as a whole

High resolution images from satellite and from eddy-resolving ocean circulation models point to an ongoing decline of the Atlantic overturning circulation, a key ocean current for our climate. Read more about it in my new blog article. 🌊

RealClimate: High-resolution ‘fingerprint’ images reveal a weakening Atlantic Ocean circulation (AMOC)
The #AMOC is the reason for Europe’s mild climate. Evidence that it is slowing has been piling up over the years – it now is likely at its weakest in at least a millennium, and it may even be approach...

This is absolutely staggering.
Record warm ocean temperatures continued in September across the North Pacific Ocean, with a number of consequential impacts (including on downstream weather patterns).

This graph shows the average for a band across the midlatitudes for every September from 1854-2025 using @noaa.gov ERSSTv5 data.
