Ist of December so my mother is baking gingerbread men, and I’m really not sure if there’s something wrong with her oven or this is some kind of death threat.

Great to see members of our 'IR' team coming together in Greenwich, southeast London, to exchange knowledge and build skills around nature-based solutions for flood prevention. From exploring effective leaky dams to sharing best practices, it was a valuable day of collaboration and learning.

Spot the find. An easy one. Mudlarking is about ‘getting your eye in’, i.e. looking for perfect shapes & colours of artefacts that don’t appear naturally among the stones, gravel, mud, sand and rubble of the Thames Foreshore. Scanning as I walk, a pop of green grabs my attention. A child’s marble.

Some tiny treasures from the Thames last week. The oldest is a clay tobacco pipe bowl, stem is missing, but dating from 1640-1680. Partial Georgian-era buckle, made from pewter, possibly from a shoe. Eurocoin token for a slot machine and a brass/paste brooch, shaped like a bow, could be 1950s.
