ACCAP Alaska Climate Webinars

  1. Webinar page:

    April 13, 2021 @ 10:00 am to 11:00 am AKDT
    Speakers: Crane Johnson, NWS Alaska-Pacific River Forecast Center and Rick Thoman, Alaska Center for Climate Assessment and Policy (ACCAP)

    Winter and early spring 2020-21 featured big swings in the prevailing storm track, resulting in big swings in temperatures and snowfall around Alaska. Crane Johnson with the NWS Alaska-Pacific River Forecast Center will review break-up basics and an overview of current conditions. ACCAP Alaska Climate Specialist Rick Thoman will provide the latest subseasonal outlooks that help inform the APRFC’s official break-up outlook.

    Speaker: Jessica Cross, Oceanographer, NOAA Pacific Marine Environmental Laboratory

    Over the last decade, ocean acidification (OA) has emerged as one of the most prominent issues in Alaskan marine research, and a possible threat to culturally and commercially important marine resources. Multiple communities around the state are now engaged in their own OA studies and monitoring, and are asking a common question: what risks does my region face? These are especially salient questions for Alaskans, given that the intensity, duration and extent of OA events have been greater than other ocean basins. Given the pace of the observed changes due to OA around Alaska, the area is commonly referred to as a bellwether and the proverbial “canary in the coal mine” for the rest of the global ocean. Here, we will take a look back at the last ten years of OA research in the Bering Sea, and highlight new, cutting-edge biogeochemical modeling, forecasting, and projection efforts that have dramatically increased our capacity to understand Alaskan OA from a large-scale perspective just in the past year. For example, we have scaled point observations to the entire Bering Sea shelf to show that corrosive conditions have covered almost 60% of critical habitat areas in the last ten years, and forecasts indicate that 2020 was even more strongly corrosive compared to the 2003-2019 average. These new insights have been quickly picked up by our colleagues engaged in ongoing laboratory studies of species-specific OA vulnerability and larger-scale ecosystem and bioeconomic analyses of OA impact. Our goal is to continue refining our capacity to identify new risks and emerging resilience of Alaskan ecosystems, and guide sound, evidence-based decisions that support sustainable marine resources in the future.

    In the last couple years, SE Alaska has experienced historically unprecedented drought and now historically extreme rainfall. These events have challenged management of regional infrastructure, affected local and regional ecosystems, and more importantly, real consequences for people living and working in the region. Are they just natural variability, chance one-time weirdness, or harbingers of what is to come? Putting these recent events in context of our historical experience helps us understand droughts and deluges now and make sense of just how uncommon they really are in the past. Using the best climate science available, we can also ask how likely these kinds of events may be in the future given what we know about climate change and its impacts on extremes. And we can try to make sense of the risks involved and what the science suggests we can do about adapting to the future before it gets here. Join Rick Thoman, Rick Lader, and Jeremy Littell for a webinar about the past, present and future of precipitation extremes in southeast Alaska.

    Issued annually since 2006, the Arctic Report Card is a timely and peer-reviewed source for clear, reliable and concise observational information on the current state of different components of the Arctic environmental system relative to historical records. The Report Card is intended for a wide audience, including scientists, teachers, students, decision-makers and the general public interested in the Arctic environment and science. This webinar will give a broad overview of the 2020 Arctic Report Card followed by Alaska-focused highlights on the following topics:
    Air temperature
    Coastal permafrost
    Greening of the tundra

    The full report card was released on December 8th. Please check out the full Arctic Report Card and then tune into this webinar to learn more focused on the Alaska context.

    November 10, 2020 @ 10:00 am to 11:00 am AKST
    Speakers: Dr. Dana Brown, Dr. Laura Oxtoby, and Dr. Chris Arp
    Investigators, Fresh Eyes on Ice Project
    University of Alaska Fairbanks

    The timing of freeze-up and winter conditions have changed throughout Alaska, and this has consequences for our ecosystems and our way of life in the winter season. Changing ice conditions and their influence on our winter travel and recreation safety has motivated the UAF Fresh Eyes on Ice project, a new freshwater ice observation network across Alaska. This seminar will provide an overview of freeze-up science and how you can be involved in helping share freeze-up and other ice condition observations this winter.
