PAGES NewsletterThe work of Steffen Holzkämper and Peter Kuhry from Stockholm University has been featured in an article in the PAGES newsletter.

PAGES (Past Global Changes) is a community of scientists whose research is aimed at understanding the Earth’s past environment in order to make predictions for the future.

The research (carried out as part of this project and a previous project called GLIMPSE) looked at stable carbon and oxygen isotopes in tree ring cellulose. The data may help to shed further light on the climate prior to the instrumental data period.

Traditionally, tree ring width or density is measured to indicate past summer temperatures but this new approach may tell us something about winter precipitation too.
