No session this month.
Hannibal Barca lost his right eye due to a severe eye infection while marching his army through the flooded marshes of the Arno River in Italy in the spring of 217 BCE.
Luckily, thanks to Modern medical science, I don't have to suffer that, merely a battery of antibiotics and salves.
I'm almost entirely back to normal, but the past week or so has been a bit of a trial in terms of attempting to concentrate, so it is with regret that I will defer tomorrow's topic for Science Tech nature (and likely pick another topic the first Wednesday of next month).
Below is tomorrow's web presentation:

AMOC (Atlantic Meridional Overturning Circulation) collapse is coming. How bad? 

• Example - Central Mexico:
  AMOC collapse would make Central Mexico drier and more drought‑prone by shifting the tropical rain belt southward, weakening the North American monsoon system that supplies summer rain, and altering storm tracks that affect the region.

• Example -Great Lakes: Winters would become more stormy, the growing season would likely shorten, precipitation patterns would shift, and Great Lakes water levels and ice cover would become more erratic.

• Example, Northern Europe - abrupt, severe cooling—especially in winter—alongside much drier summers, more intense cold extremes and storms, and significant knock-on effects for agriculture, energy, and coastal sea levels.
