6. The signal (climate change)
The noise (weather)
…To tell data-driven climate stories…
7. I would not be a scientist
today without the support of
federally funded research.
Mount Washington, New Hampshire –
“Home of the world's worst weather”
Me, with my new handheld anemometer
measuring 50+ mph wind gusts – late 2000s
My weather journals – 2005
14. THE ARCTIC IS
CHANGING
IN REAL-TIME.
Daily Arctic temperature in
2018 (red) compared to
every year since 1958 in the
month of February. Average
is shown by the white line.

34. • Describes the current state of
different components of the Arctic
system relative to historical
records
• Issued annually since 2006
• 97 scientists from 11 countries
• Aimed for a broad audience
• Observations inform model
development and needs

“…great warming of the
lower layers of the
troposphere over the
Arctic basin... In fact,
there is a lowering of
mid-latitude continental
temperatures near the
surface”

My career would not have been possible
without amazing mentors, colleagues,
and federal research support.
87. TAKEAWAYS & THANK YOU!
Climate change impacts have already emerged in the Arctic.
Improvements to observations and models will reduce uncertainty
More resources are needed for polar science to improve prediction,
projection, and understanding of Arctic system change
