We present the results of pollen analysis performed on an ice core recovered from Nevado Sajama, Bolivia, dated to 25 ka BP. Low pollen concentrations from 25 to 15 ka BP are consistent with the scenario of an expanded ice cap surrounded by sparse vegetation and cold conditions on the Altiplano during the Last Glacial Maximum. -

Guallatiri Volcano (18°25’S, 69°05’W) is a large edifice located on the Chilean Altiplano near the Bo- livia/Chile border. This Pleistocene-Holocene construct, situated at the southern end of the Nevados de Quimsachata chain, is an andesitic/dacitic complex formed of early stage lava flows and later stage coulées and lava domes. -

GRID-Arendal Annual Report 2018
29 and counting GRID-Arendal Annual Report 2018 Established in 1989 as a non-profit foundation under Norwegian law, GRID-Arendal’s mission is to create environmental knowledge that encourages positive change. We do this by organising and transforming available environmental data into credible, science-based information products, delivered through innovative communication tools and capacity building services targeting relevant stakeholders. GRID-Arendal works closely with United Nations Environment, other UN agencies and partners around the world to connect science to policy. Our goal is to shorten the distance between the emergence of new science and policy actions. We seek to influence thinking and action at the level of the global community on issues that require collective efforts because many problems cannot be solved at the national level alone. Acknowledgements GRID-Arendal would like to acknowledge the support of the Government of Norway and its other funders, partners and supporters.
