Arctic speleothems reveal nearly permafrost-free Northern Hemisphere in the late Miocene

Arctic speleothems reveal nearly permafrost-free Northern Hemisphere in the late Miocene

Abstract Arctic warming is happening at nearly four times the global average rate. Long-term trends of permafrost dynamics cannot be estimated directly from monitoring of present-day thaw processes, requiring paleoclimate-proxy information. Here we use cave carbonates (speleothems) from a northern S...
