For those of us who love boron for what it can tell us about past ocean pH and atmospheric CO₂, this is a fun reminder of just how versatile this remarkable element really is. Paging @thefosterlab.bsky.social www.nature.com/articles/d41...

There’s a new form of boron — and it’s really weird
A boron phase prepared under pressure is a million times more conductive than chemists expected, and can be stretched.

I often despair about the state of our climate (especially after this summer), but this plot of high-end emission scenarios from successive IPCC reports is a welcome bit of good news and shows how far we have come. Still a long way to go but we have started. see www.carbonbrief.org/explainer-th....
Fossil CO2 emissions relative to 1850-1900 for the highest scenario of each climate modelling generation: SRES A1FI (CMIP3, used in AR4), RCP8.5 (CMIP5, AR5), SSP5-8.5 (CMIP6, AR6) and CMIP7’s high, all run through AR6-calibrated FaIR ensemble. Data: SRES database v1.1, RCMIP v5.1, ScenarioMIP database; chart by Carbon Brief. A1F1, RCP8.5 and SSP5-8.5 all increase way faster than current IPCC AR7 High Emission Scenario.

Wake up, babe. The Prime Minister just dropped “hydronym”.
The name Lake Ontario comes from the Wendat word Ontari’io, which, appropriately, means “the lake is beautiful, the lake is big”.

The name is more than 400 years old, predating both the Confederation of Canada and the Declaration of Independence of the United States of America.

We know that America is changing. Their trading relationships, their foreign policies, their national monuments, their hydronyms. 

Canadians also know that naming reality means calling it Lake Ontario – then, now and always.
