We are delighted to announce the return of the Half-Baked Seminars. Mick Griffiths is going to start things off for us by presenting some of his work on speleothems from Laos and Flores and perhaps giving us a sneak peak at where he'll be heading this summer on fieldwork.

In order to most accurately identify the causes and mechanisms of climatic change, it is necessary for us to develop high-resolution paleoclimate records which tell us about past climate changes on seasonal, annual, and decadal timescales.  Calcite speleothems are well suited for paleoclimate reconstruction because they are normally pure calcite, are well-preserved, can be precisely dated using Uranium-series methods, and contain multiple types of paleoclimate proxy data in their highly resolvable growth bands.  In particular, measurements of δ¹⁸O along speleothem
