We opted to join Bainbridge Island’s rally, which had well over 1K+ protestors. One of the speakers we heard was a Japanese American internee who, in 1942, was removed from Bainbridge Island to an internment camp with her family. Her closing words:
“Never again is now.”

All surface temperature products for 2024 are now live.
All show 2024 is the warmest year (very clearly).
The estimates of the change since the pre-industrial (1850-1900) are more uncertain but range from 1.46 to 1.62ºC.
It is therefore *likely* this was the first year that exceeded 1.5ºC.

Norepinephrine-mediated slow vasomotion drives glymphatic clearance during sleep
Norepinephrine oscillations during NREM sleep drive synchronized changes in cerebral blood volume and cerebrospinal fluid, promoting glymphatic clearance. Optogenetic and pharmacological manipulations confirm that vasomotion, regulated by norepinephrine, acts as a pump for brain fluid transport.
