Something special to share. I’ve been up to my old tricks again – scanning, restoring, and researching a collection of over 600 Edwardian-era glass slides that were found in an attic.
I've connected them to Birmingham schoolmaster and amateur photographer Charles Francis Hayward.

Now that the Sept and Oct data are (belatedly) in, it looks like 2025 will be the second warmest year in the record (~80% probability). The last three years are in a class of their own.

#Melissa has made landfall in #Jamaica, and has preliminarily tied the record for the lowest pressure of any landfalling hurricane in Atlantic history: 892 mb. That was last observed 90 years ago with the 1935 Labor Day hurricane.
The storm does not look like it even notices Jamaica being there.
