Recent summer warming in northwestern Canada exceeds the Holocene thermal maximum

Traditional precipitation isotope archives (e.g., ice cores) are fundamental to our knowledge of past climate but limited to glaciated locales. Here the authors show that pore ice in relict permafrost holds equal promise as a proxy and use it to provide insights on the Holocene summer climate histor...

Description
Summary:Traditional precipitation isotope archives (e.g., ice cores) are fundamental to our knowledge of past climate but limited to glaciated locales. Here the authors show that pore ice in relict permafrost holds equal promise as a proxy and use it to provide insights on the Holocene summer climate history of northwestern Canada.
