"The idea, Yedvab explained, is that “instead of displacing the particles out to the stratosphere and start following them, to do the other way around — to suck air from the stratosphere and to conduct in situ experiments, without dispersing essentially.”

Just doing some Chemical Ionization research with Google AI - I'm learning a lot!
Google AI says HOCl is more acidic than acetic acid because it has a higher pKa Google AI says a higher pKa means a weaker acid.

Scientists long believed that Prochlorococcus, the smallest and most abundant phytoplankton on Earth, would thrive in a warmer world. But new research suggests the microscopic bacterium will decline sharply as oceans heat up. @uwnews.uw.edu

For years, researchers have hypothesized that westerly winds were ferrying warm water toward the West Antarctic Ice Sheet, accelerating ice melt. A new @uwess.bsky.social study flips the existing narrative on its head, pointing toward winds from the north instead.

That said fires are also in BC too 😬
