Despite its rapid response to global warming, reflected in accelerating permafrost thaw, intensifying wildfires, and increasing number of extreme events like droughts and floods, the environmental history of continental Eurasia remains poorly understood, due largely to availability of suitable archives.\u00a0<\/span>\u00a0<\/span><\/p>\n I will introduce cave deposits as key archives for continental palaeoenvironmental changes. I will present some results of my team\u2019s work and discuss opportunities and challenges when working with speleothems in permafrost regions. Ongoing work reveals a rich history of environmental changes in Siberia and Mongolia since the Miocene. Using innovative analytical tools like clumped isotopes and organic geochemistry we gain fresh insights into past temperature, vegetation changes and moisture supply that are intimately linked to circulation dynamics. Going ca. 6 million years back in time, we can start to tap into continental climate changes in a warmer-than-modern world, but we also face new challenges that require novel methods and interdisciplinary collaboration. <\/span>Linking multiproxy reconstructions with model output we should be able to estimate possible near-future scenarios for permafrost, precipitation, and vegetation changes deep in Eurasia and associated repercussions for society.<\/span>\u00a0<\/span><\/p>\n<\/div>\r\n <\/div>\r\n <\/div>[\/vc_column][vc_column width=”1\/3″][vc_single_image image=”165718″ img_size=”full”][\/vc_column][\/vc_row]<\/p>","protected":false},"excerpt":{"rendered":" [vc_row][vc_column width=”2\/3″][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”165718″ img_size=”full”][\/vc_column][\/vc_row] […]<\/p>\n
