Muted multidecadal climate variability in central Europe during cold stadial periods ...

Here, we present a near-annual-resolution climate proxy record of central European temperature reconstructed from the Eifel maar lakes of Holzmaar and Auel in Germany spanning the past 60,000 years. The lake sediments reveal a series of previously undocumented multidecadal climate cycles of around 2...

Description
Summary:Here, we present a near-annual-resolution climate proxy record of central European temperature reconstructed from the Eifel maar lakes of Holzmaar and Auel in Germany spanning the past 60,000 years. The lake sediments reveal a series of previously undocumented multidecadal climate cycles of around 20- to 150-years that persisted through the last glacial cycle. The periodicity of these cycles suggests that they are related to the Atlantic multidecadal climate oscillations found in the instrumental record and in other climate archives during the Holocene. Our record shows that multidecadal variability in central Europe was strong during all warm interstadials, but was substantially muted during all cold stadial periods. We suggest that this decrease in multidecadal variability was the result of the atmospheric circulation changes associated with the weakening of the AMOC and the expansion of North Atlantic sea ice cover during the coldest parts of the last ice age.Organic carbon was determined by measuring the ...
