Responses of Arctic black carbon and surface temperature to multi-region emission reductions: a Hemispheric Transport of Air Pollution Phase 2 (HTAP2) ensemble modeling study [PDF]

Atmospheric Chemistry and Physics, 2021
Black carbon (BC) emissions play an important role in regional climate change in the Arctic. It is necessary to pay attention to the impact of long-range transport from regions outside the Arctic as BC emissions from local sources in the Arctic were ...

Mercury in Sediment Core Samples From Deep Siberian Ice-Rich Permafrost

Frontiers in Earth Science, 2021
We determine Hg concentrations of various deposits in Siberia’s deep permafrost and link sediment properties and Hg enrichment to establish a first Hg inventory of late Pleistocene permafrost down to a depth of 36 m below surface.

A multi-model assessment of pollution transport to the Arctic. [PDF]

, 2008
We examine the response of Arctic gas and aerosol concentrations to perturbations in pollutant emissions from Europe, East and South Asia, and North America using results from a coordinated model intercomparison. These sensitivities to regional emissions

Accelerated decline of summer Arctic sea ice during 1850–2017 and the amplified Arctic warming during the recent decades

Environmental Research Letters, 2021
The 168 year trends of summer (July–September) sea ice area (SIA) variations in six Arctic regions during 1850–2017 are analyzed. SIA has been significantly decreasing in most Arctic regions since 1850.
