Thanks Keith!

>the obvious one from my viewpoint should be Volcanoes . There is my Tree-density/eruption curve (see Figure 5 in attached paper) and the evidence of effects seen in instrumental data (tried to attach paper by Jones et al - also has tree-ring links- but too long so posting it to you.) By the time of the meeting we will have much longer (minimum 2000 year series of reconstructed temperatures for Fennoscandia, Urals, Taimyr ) and the integrated signal compared to volcanic forcing.

>>I will be one of the keynote speakers during the HOLIVAR conference in London next June. I intend to focus on holocene climate variability at decadal-centennial time scales, based on the evidence from proxy records. I already have several good examples of climate change and the effect on populations living in hydrologically marginal areas (Michel Magny's lake level records and my own studies focusing on raised bogs). So the societal/archaeological dimension is already well covered.

>>However, these examples focus on the evidence for solar forcing of climate change, and each HOLIVAR keynote should be a state-of-the-art synthesis, not just a presentation of results from the speakers own lab (which in my case mainly relate to the evidence for solar forcing of climate change). I ask you to suggest some ('non-solar') examples of studies with evidence for climate shifts at decadal-centennial caused by other climate forcing mechanisms. Your ideas and materials are most welcome, preferably within the next two weeks.
