Transported: every convict ship to Australia, mapped

Pirate hotspots, then and now

I mapped 7,511 pirate attacks from 1993 to 2020 and followed the hotspots as they moved, from the Strait of Malacca to Somalia and the Gulf of Guinea. In 2025 the busiest pirate waters were the Singapore Strait, and in 2026 Somali hijackers are back.

Cold years, witch years? Scotland’s witch panics and the Little Ice Age

Scotland accused 3,840 people of witchcraft between 1563 and 1736, 57% of them in five sudden panics. I mapped where they lived and tested whether the panics followed cold years. They did not.
