Pre-JIRP Readings: IPCC AR5 Summary for Policy Makers

These questions come to us, again, from both Dr. Shad O'Neel and Dr. Jeffrey Kavanaugh and are related to the second reading on the required pre-JIRP reading list. Please read, reflect, and provide your input in the comments section. 

From Dr. O'Neel:  How does the confidence presented in IPCC AR5 SPM compare to public perceptions of climate change?  What do these venues base their positions on?  Do you feel that the claims made in the SPM are well-justified?

How does glacier change contribute to the global sea level budget?  Summarize the different components of this budget, and identify any common misperceptions that are associated with sea level rise. Why are ice dynamics (what are ice dynamics) important to sea level budgets?

This document is loaded with statements that end like this: {6.5, 7.7} which are references to the full IPCC report available here: 

We encourage you follow at least one of these linkages to explore a topic of interest to you in greater detail. 

From Dr. Kavanaugh: Shad offers good questions here. I will just add to/clarify one of them: The authors of the IPCC AR5 state that that "Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia." Briefly summarize the distinct lines of evidence drawn upon to support this conclusion.

We hope that in addition to your readings, you are staying active and keeping up your fitness so that you arrive in Juneau ready to go! Cardio and core work are both important.


An Interview with Dr. Anthony Arendt

By Patrick Englehardt

Glaciologist Anthony Arendt grew up in Edmonton, Alberta, where his deep connections to the Canadian Rockies fostered his love for science and nature. Growing up Anthony often visited the Athabasca Glacier, where he fondly recalled traveling onto the glacier in track vehicles with his family. Once in college his passion for mountaineering and science was fostered, and he decided that he wanted to pursue a career in Earth science where his passions could be fulfilled.

Patrick Englehardt: What is your research focus?
Anthony Arendt: I focus on understanding how glaciers change in response to climate, with an emphasis on predicting how global sea level and local water resources are affected.

Patrick Englehardt: Where has your research taken you?
Anthony Arendt: My first glacial project took place on Ellesmere Island in northern Canada, where I spent three summers conducting research.  I have also traveled to the North West Territories, Alaska, Greenland, and Antarctica.

Patrick Englehardt: Why do you conduct your research?
Anthony Arendt: Glacial change is a large contributor to rising sea level, which has significant societal impacts and global implications. It is especially important to understand how these changes will affect coastal communities, local water resources and agriculture.

Patrick Englehardt: What has been your greatest challenge?
Anthony Arendt: The first few years of my PhD were really challenging. During this time I figured out that Alaskan field work had a steep learning curve. I had to hone my mountaineering, glacial travel and survival skills and deal with the incredibly remote Alaskan wilderness. During the second year of my PhD I had a harrowing experience, falling into a glacial river and losing all of my glacier gear. This was the low point of my career and I seriously thought of quitting.

Patrick Englehardt: What kept you from giving up?
Anthony Arendt: I had a lot of support from family, friends and colleagues, all of whom encouraged me not to give up. I think my interest in glaciers also kept me going, and I knew that I could not learn all of these amazing things anywhere else but in Alaska. I’m glad I never gave up and I stuck with it, because my career improved after that.

Patrick Englehardt: Who was your greatest inspiration growing up?
Anthony Arendt: As a scientist it was David Suzuki. I remember, as a kid, watching him on television every week. He introduced me to new ideas about how we can care for the planet and mitigate climate change. What impressed me most was his honesty, something that has always stuck with me as I have strived to be fact-driven and honest with my research. Also I have been inspired by every advisor I have had during my career. Each has been a great mentor in their own right and helped me along the way.

Patrick Englehardt: How did you hear about JIRP?
Anthony Arendt: When I moved to Alaska in 2000 I heard about JIRP from a myriad of people, and I always wanted to take part in the program.  I had hoped to participate as a student but schedules and research always kept me from doing that. Jeff [Kavanaugh] approached me and asked if I would teach this year at JIRP and I happily obliged.  I was excited to finally be part of the long historical legacy of the many others before me, including my PhD supervisor [Keith Echelmeyer].

Patrick Englehardt: What suggestions would you have for aspiring scientists?
Anthony Arendt:
Students interested in a scientific career face numerous opportunities, and also many challenges. In addition to learning a broad range of technical and mathematical skills, scientists need to develop strong communication skills, due to the highly collaborative nature of research today. At the same time, we know some of the greatest scientific discoveries come from long periods of working in solitude. So, finding educational opportunities that balance these elements is really important.

Patrick Englehardt: Do you believe that there are educational opportunities where aspiring scientist can gain these skills?
Anthony Arendt:
I believe that JIRP provides great opportunities for developing these skills. I cannot think of a better environment for aspiring scientist to hone their research and safety skills while fostering a strong sense of community. At JIRP, students work towards a common goal while simultaneously conducting unique scientific research.  JIRP is an excellent microcosm of the real scientific community where a love of nature and science connect people and connections are made for life.

Patrick Englehardt: If you had not become a scientist what would you do?
Anthony Arendt:
No question, I would be a famous Jazz musician! I looked into musical colleges and I play piano, and I continue to play as a hobby.
