Field: In this
talk, Dr. Ellen Field will discuss how education is, and, has been an
overlooked mitigation strategy and how education policy can be
instrumental as part of a multi-pronged approach to reducing greenhouse
gas emissions. Gaps in current education policy at Canadian regional
jurisdictions (provincial and territorial) and national levels will be
discussed along with best practices of climate change education from
empirical research studies. In addition, this talk will consider
lessons the formal education system can learn from the youth climate
justice movement, and possible pathways for responsive education
systems that focus on transformative and transgressive pedagogies.
Audience members will take away insights on how education is
instrumental to climate action and suggested ways to engage various
segments of the population in climate change education.

Science and Inuit both have ways of knowing with a rich understanding
of climate, the ocean and sea ice. These understandings are distinct
and independent, yet complementary. Is it possible to bridge these two
knowledge systems so as to inform each from the other? Is it even
desirable? As a Labrador Inuk working in the scientific field of
oceanography I have spent the four years exploring these questions.
While they cannot be answered simply, I will provide my perspective and
experience working at the interface between scientific and Inuit
knowledge of the ocean. My research team and collaborators in the
Nunatsiavut Government and in Inuit communities in the region, have
been undertaking a number of related project and activities along these
lines. Inuit knowledge of the coastal ocean and sea ice is being
documented using participatory mapping and interview methods. We are
developing ways recording Inuit observations of the environment, rooted
in and referencing local traditional knowledge and focusing on that
which Inuit consider important and of value. Scientific measurements of
coastal ocean temperature, salinity, and ocean currents are being made
through community-based monitoring programmes with representation in
most communities in Nunatsiavut who are providing their expertise in
choosing locations, times, and methods of accessing field sites.
Finally, we are developing numerical ocean models for the region with
Inuit Knowledge providing both ground-truths against which we can
validate the model as well as informing hypothesis and model
experiments. We have also been exploring the role that land-based
activities, including research workshops, can play in this process. We
are encouraged by the points of contact between science and Inuit
knowledge that have emerged - such as maps, conceptual models,
hypotheses - and that these can play the role of boundary objects to
facilitate dialogue between these two knowledge systems.
Humphreys:
The
Hudson Bay Lowlands (HBL) is the largest contiguous peatland complex in
North America. Although peatlands
are
large stores of carbon, they are a natural source of methane (CH4),
a potent greenhouse gas. However, it remains uncertain how much CH4
is emitted by the HBL peatlands and how ongoing climate change will
impact these emissions.
We measured CH4
fluxes using the eddy covariance technique at four HBL peatland sites
with different vegetation and peat characteristics over several years.
Total seasonal emissions ranged from 2.6 to 7.2 g CH4 m-2
(Apr 1 – Nov 30) with the highest values at the wettest and warmest
peatland, a patterned fen, and the lowest at the driest and coolest
peatland, a raised peat plateau with permafrost. Year-to-year
variability in CH4 emissions was less than site-to-site
variability. These measurements can help constrain recent
top-down estimates of HBL-wide CH4 budgets. We also
discuss how these measurements can help us understand the potential
impacts of warming, drying and thaw on HBL CH4 emissions.
Andersen:
The final 15
kilometres of the Dempster Highway within the Yukon (YT km 450-465) -
known as Hurricane Alley - experience strong downslope winter
windstorms. Easterly winds blow perpendicularly across the highway
after topographic enhancement by a north-south ridge east of the road.
The ECCC Rock River meteorological station recorded 88 hours of
sustained wind speeds above 75 km/h during winter 2020/21. The
windstorms frequently cause road closures and hazardous conditions for
motorists. ECCC wind forecasts are often inaccurate since the modelled
grid cells are much larger than the ridge; however, recent UBC
modelling suggested that using smaller grid cells should increase
accuracy. In October 2021, seven additional local meteorological
stations were installed to measure winds. This talk will discuss the
state of the research on Hurricane Alley windstorms, and the use of
synoptic tools (ECCC analysis charts and NOAA HYSPLIT model results) to
explain atmospheric conditions responsible for the windstorms.
Schletselaar:
Climate warming is causing rapid and widespread environmental change in
northern regions. Transportation networks in Canada's North are
becoming increasingly vulnerable to the impacts of climate change.
Rising ground temperatures and permafrost thaw have been a main cause
of road damage as the bearing capacity of the ground is significantly
reduced and subsequently subsides, leading to differential settlement
of the road surface. Other road damage is due to increased
precipitation which causes road washouts, icings, damage of culverts
and landslides. Under current climate trends, it is expected that
highway infrastructure in northern communities will require increased
maintenance, incurring significant costs, in order to meet functional
standards.
This presentation will outline a quantified assessment of climate
change-induced maintenance expenditures for highways in Yukon. Changes
in expenditures linked to climate conditions will be discussed in
relation to underlying permafrost and ground ice conditions.
Gruber:
The
Special Report on the Ocean and Cryosphere in a Changing Climate
(SROCC) revealed the benefits of ambitious mitigation and
effective adaptation and, conversely, the escalating costs
and risks of delayed action. But how do we best enable
this effective adaptation and ambitious mitigation when it
comes to permafrost thaw? In this presentation, I will explore the
potential role of operational services. With the framing
of climate services, several distinct challenges can be identified
for permafrost climate services: (1) history – climate
services evolved from e.g., National Weather
Services, whereas permafrost services are rarely established, (2)
perception – permafrost areas are in the periphery and
hazards affect relatively few people directly, and (3)
processes and paradigms – a new combination of research and
capabilities related to the atmosphere and the subsurface are
needed to generate future scenarios of permafrost thaw.
Emerging permafrost climate services and initiatives will be
discussed to illustrate the growing momentum that exists in
Canada, for example NSERC PermafrostNet, and globally.
Betts: This
talk will be based upon this recent paper which I suggest you scan.

This
examines our understanding of climate change, as well as the reluctance
of industrial societies to deal with the drivers, especially the
burning of the fossil fuels, before the consequences become
catastrophic. I have worked as a professional scientist for 50 years,
but I also realized 50 years ago that science alone is not enough to
deal with pressing global issues, as it lacks a moral framework—it
lacks wisdom. So I decided it was also my responsibility as a
scientist to develop the skills to map out what drives the social
framework and the social assumptions. I contrast the
Earth-centered indigenous worldview needed for our survival (which has
been systematically destroyed), with the industrial capitalist mindset
of the Fossil fuel Empire that is destroying our stable climate to
maximize profits. We review briefly the long history of the
misuse of human power, and the rise of science and technology without a
guiding moral framework. But the deceit and bribery of
politicians by the Fossil Empire are no match for the Earth system
response. We are seeing new climate extremes on a global scale that are
destroying our fossil fuel and economic infrastructure in an attempt to
save some of the Earth’s ecosystem.
Kimbell
& Delisle: In 2017, the
Government of Canada announced the replacement of its weather radar
network. At the time, the network consisted of 31 radars, including two
operated in partnership with the Department of National Defence and one
owned by McGill University. A contract was awarded to buy and install
32 to 33 new radars. They are S-band (10 cm) radars, and utilize
dual-polarization technology. One of the radars is located in
Franktown, in eastern Ontario, and was just commissioned (August 2021).
The presentation will provide an overview of the network, the new
technology, and the resulting improvement in our ability to forecast
the weather in eastern Ontario. The website www.weather.gc.ca is
getting a makeover that will allow you to view more weather products
and services. You probably noticed on March 29 that the RADAR product
changed on your favorite weather website! This was a first step towards
transforming the site, which now offers products and services
geo-referenced on a single map of Canada. As with every transformation,
a lot of reactions and adjustments were necessary. We will be happy to
provide you with an overview of the changes and improvements available
now and in the future.
