Holocene-length alkenone-based summer temperarature record from Arctic Svalbard lake sediments
Abstract: Situated at the crossroads of global oceanic and atmospheric circulation patterns, the Arctic is a key component of Earth's climate system. Amplified by sea-ice feedbacks, even modest shifts in regional heat budget drive large climate responses. This is highlighted by the amplified re...
