Dear Stephen,
You are wrong about the Earth's energy balance. While more energy
indeed reaches the top of the atmosphere at the North Pole in summer
than at the Equator, due to atmospheric scattering because of the long
path length and much higher planetary albedo due to snow, sea ice, and
low clouds, much less energy reaches the surface and is absorbed by the
climate system at the North Pole than at the Equator.

Hi All
I hope that this will be interesting. For a month either side of the
summer solstice there is more heat going into the North pole than the
equator.

SPEAKER
My research focuses on the interaction between the atmosphere and
cryosphere in the polar regions and mountains. More specifically, I
investigate the spatial distribution, frequency and impact of
atmospheric processes on surface melting of glaciers and ice shelves.
So far, I have focused on the Larsen C ice shelf, 79N glacier
(northeast Greenland) and the Patagonian ice fields.
I am passionate about science communication and regularly participate
in and organise workshops, events and lectures for a variety of
audiences. Most recently, I participated in the ‘long night of
science’ at Friedrich Alexander University and spoke with journalists
and radio hosts about climate change in the Arctic.
I started my position at Arctic Frontiers on 1^st January. This is an
organisation which creates dialogues between scientists, policy
makers, governments and local communities in the Arctic. From April
2019 to April 2021 I was the Early Career Scientist (ECS)
representative for the cryosphere division of the European Geosciences
Union (EGU). As part of this role, I communicate the needs and voices
of the division with council members of the union. I have organised
webinars on careers outside of academia and chaired a debate focusing
on the balance between conducting science and reducing our carbon
footprint.
In August 2017 I defended my PhD on the spatial and temporal
distribution of föhn winds and their impact on the Larsen C Ice Shelf,
Antarctica. I studied for my PhD jointly with the British Antarctic
Survey and the University of Leeds.
ABSTRACT
Nioghalvfjerdsfjorden or 79° North Glacier drains approximately 8% of
the Greenland ice stream and is the largest remaining ice shelf in the
Arctic. Since the mid 2000's, the glacier has been thinning,
retreating and melting at a faster rate. In 2019 and 2020, two large
icebergs calved following exceptionally warm summers. The glacier has
a floating tongue, which extends approximately 80km into the ocean,
which means the glacier is exposed to both a warming ocean and a
warming atmosphere. During winter, the passing of storms along the
coast can raise the air temperature to the melting point and produce
rainfall. In winter, atmospheric rivers pass over the ice sheet and
produce extreme melting through the föhn mechanism. Recent evidence
suggests that melting is now occurring at a higher elevation than in
the early 2000's. In this talk, the key atmospheric processes in the
region will be presented, along with a discussion of the impact they
are having on the glacier through enhanced ice melting.
This will be a 45 minute talk followed by 15 minutes for Q&A. The
meeting will open from 5:50 pm for attendees to join and the event
will start promptly at 6 pm. Please register for the event on
www.rmets.org <http://www.rmets.org/> and join the meeting using
Google Chrome. Please note that joining instructions will not be
provided unless you have registered.
