The Alaska Center for Climate Assessment and Policy announces the
availability of a webinar entitled "A Collaboration with Rural Alaskans:
The Driftwood Harvest in a Changing Climate," which will take place on
Tuesday, 19 July 2016 at 10:00 a.m. AKDT. The speaker for this webinar
will be Chas Jones, EPA Post-doctoral Fellow.
Webinar Summary: This study examined flood events in the Yukon River
with the goal of understanding how actual or perceived changes in
driftwood availability are related to river hydrology and how future
changes in hydrology may affect the driftwood harvest. The researchers
combined information gathered from informant interviews, USGS gauging
stations, U.S. Census data, and numerical models of past driftwood
harvest rates to estimate changes in future driftwood harvest rates. The
researchers determined that neither average date of spring break-up nor
the June Rise floods had changed significantly between 1977 and 2012,
but the date of the June Rise had become much more variable since 1993.
The model indicated that hydrologic factors alone were responsible for a
small (3%) decrease in the annual wood harvest. However, the
installation in the village of wood-fired boilers in 2007 increased the
annual community demand by more than 80%. Thus, greater uncertainty of
accessing driftwood has been accompanied by a higher demand for this
important fuel source. We also identify a driftwood harvest threshold
and suggest that when flows exceed 325,000 cfs at the USGS Gaging
Station at Stevens Village on the Yukon River, driftwood can be
predicted to flow past Tanana approximately 2 days later. Modeling
various climate scenarios illustrate how the driftwood model estimates
that increasing hydrologic variability would be expected to increase
vulnerability of the driftwood harvest. Examination of the economics
associated with using driftwood versus fuel alternatives shows that
other wood sources require more time and money to harvest. Furthermore,
the use of oil or electricity as alternative fuels cost substantially
more, but save considerable amounts of time.
Participation in person is also available at the University of Alaska
Fairbanks, Akasofu Building, Room 407.

Friday, 22 July 2016
The Alaska Center for Climate Assessment and Policy (ACCAP) will host a
webinar entitled "National Weather Service Alaska Climate Forecast
Briefings (July 2016)." The primary speaker will be Rick Thoman,
National Weather Service Alaska Region.
Webinar Summary:
Do you lie awake at nights wondering what the upcoming
season will be like? Want to place bets with friends and family on next
month's weather? If so, good news:
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. Rick Thoman (Climate Science
and Services Manager, Environmental and Scientific Services Division,
National Weather Service Alaska Region) will review recent climate
conditions around Alaska, review forecast tools and finish up with the
Climate Prediction Center's forecast for the upcoming season.
Participation in person is also available at the University of Alaska
Fairbanks, Akasofu Building, Room 407.
