~(10)Be ice core record unlocks history of Holocene solar activity

摘要

The impacts of temporal variations in cosmic radiation and solar activity on global climate change remain unclear. Ice cores and tree rings record the production of radionuclides like 10Be and 14C, which form when cosmic ray particles react with atmospheric nitrogen and oxygen, but isolating the solar signatures within these climate proxies has proven difficult.
