We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.
Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

The median date for global sea-ice extent to hit its annual maximum is November 2nd. That was yesterday.
It's looking like 2025 may end up with the second lowest global sea-ice maximum since records began in 1988, behind only 2024. And 2016 is just barely higher.
Stay tuned!

The drier the eye, the stronger the storm. Here's hoping that eyewall weakens, or Jamaica is in real trouble
Hurricane Melissa has just broken the record for the driest eye ever observed in a tropical cyclone, with a temperature of -4.75°C.
This is nothing short of astronomical.

A remarkable, and ominous, satellite snapshot this evening of Hurricane #Melissa as it continues to move very slowly westward just south of #Jamaica. The storm will likely further strengthen into a Category 5 storm before turning northward & making landfall in Jamaica on Tue.
