The Alaska Center for Climate Assessment and Policy (ACCAP) announces two webinars.
Webinar Title: Responses of Permafrost Landscape to Surface Disturbances – Case studies in Siberian forest and Alaskan tundra
Presenter: Go Iwahana, International Arctic Research Center, University of Alaska Fairbanks
Date/Time: Wednesday, 17 June 2020, 11:00 a.m.-12:00 p.m. AKDT
Webinar Summary:
Ground-surface disturbances, including wildfires, deforestation, and climate change, alter the thermal status of permafrost leading landscape changes in Polar Regions. Given the increasing number of reports about rapid permafrost thaw and predicted occurrence of wildfires in the Arctic, it is of great social concern to know where and to what extent permafrost degradation is currently ongoing and may occur in the near future. This is true, especially in ice-rich permafrost zones, as consequential subsidence by ice-rich permafrost thaw (thermokarst) will cause significant changes in surface ecology, landscape evolution, and hydrological processes.
This presentation introduces several case studies on thermokarst subsidence observed in the field and by remote sensing in various time ranges. Field surveys and microwave remote sensing analyses were conducted to quantify thermokarst after surface disturbances in boreal forests of Northeastern Siberia and tundra fire scars in Alaska.

Webinar Title: June 2020 National Weather Service Alaska Climate Outlook Briefing
Presenter: Rick Thoman, ACCAP
Date/Time: Friday, 19 June 2020, 12:00-1:00 p.m. AKDT
Webinar Summary:
The tools and techniques for making monthly and season scale climate forecasts are rapidly changing, with the potential to provide useful forecasts at the month and longer range. This webinar will review recent climate conditions around Alaska, review some forecast tools and finish up the Climate Prediction Center’s forecast for July and the summer season. Join the gathering online to learn more about Alaska climate and weather.
