You could find your way along the Nova Scotia coast blind, just by timing the blinks. Every lighthouse flashes on its own rhythm, a set interval and colour no neighbour repeats. Sambro Island off Halifax has burned since 1758, the oldest working lighthouse in North America. #lighthouse #NovaScotia

New publication in Environmental Research Letters: overshooting 1.5°C then cooling back down does not undo the damage. We map where, for whom, and through what mechanisms temporary overshoot becomes permanent loss. Paper (OA): iopscience.iop.org/article/10.1... 1/12
"Three stacked panels sharing a time axis. Top: global temperature rises past 1.5°C, peaks, then declines (the overshoot pathway), with a flat permanent-exceedance line at the peak for comparison. Middle: biophysical responses to the same trajectory diverge; some track temperature down, some recover with a lag, one keeps intensifying. Bottom: socioeconomic impacts of the same biophysical change diverge by adaptive capacity; high-capacity systems recover, while one crosses a dashed adaptive-capacity threshold and never recovers: the permanent overshoot legacy.
