Lateglacial climate variability, impact and tele-connections
The end of the last glacial period and the transition into our present warm Interglacial (19,000–11,000 years ago) was characterised by multiple climate flips between warmer and colder states. These left their imprint in many geological archives and show up as abrupt climate shifts and dramatic ecosystem changes, involving the ocean, the atmosphere, cryosphere, biosphere and the lithosphere.
Lake sediments from southern Sweden in particular have been studied extensively to better understand the impact of these marked climatic shifts. One of these sites is the ancient lake at Hässeldala Port in southern Sweden, where studies have revealed distinct local and regional changes. Multiple articles have been published using Hässeldala's sediments as a base (see Publications).
In a new project, and using lake sedimentary records from Sweden, the southern Atlantic region and the Indian Ocean region, climatic linkages will be established through precise chronological correlations and climate model simulations.
Financial support for these projects is through grants from the Swedish Research Council and the Swedish Nuclear Fuel and Waste Management Company.
