Novel proxy – temperatures from earthworm-calcite
Novel palaeoecological proxies and methods are always interesting, offering new or better insights into the past environment. This week I found out from the BBC that earthworm poo can be used as a...

Small tornado in Bremerhaven
The last couple of days I’ve been discussing sea-ice reconstructions at the Pages Sea-Ice Proxy workshop in Bremerhaven. A huge range of proxies have been presented, ranging from traces of halogens in...
View ArticleA biased and incomplete summary of Sea Ice Proxy workshop
Sea-ice is an important component of the Earth’s climate system, for example, it greatly increases the proportion of sunlight reflected at high latitudes – the albedo of ice is ~0.6 whereas it is only...

Lasers, biomarkers and the Sun
The earliest work on Holocene palaeoecology focused on megafossils such as Pinus stumps. Then macrofossils such as hazel shells were used to reconstruct species distributions and climate. Then pollen...
