FJehn

Hi, I’m Florian. I am enthusiastic about working on large scale problems that require me to learn new skills and extend my knowledge into new fields and subtopics. My main interests are climate change, existential risks, feminism, history, hydrology and food security. I hope to find a place where I can work on some (or all?) of these topics, apply my data science skills, work in a team and share my knowledge by writing articles and giving courses and presentations. If you have similar interests or know of an organisation I would fit in well, let’s get in touch!

How to best address Repetitive Strain Injury (RSI)?

One thing I find very useful but I haven't seen recommended anywhere is simply adding a second mouse to your computer. It allows you to easily switch between both hands. This gives your main hand some rest, but doesn't overuse the other one.

Betting on the best case: higher end warming is underrepresented in research

Unfortunately, I cannot really provide conclusive answers here, as our paper only looked into the amount of research overall, but not into specific topics. Getting an overview of this is basically a major research project itself. However, a student of mine looked into this a bit and her preliminary results seem like it is more of a general problem and not specific to certain fields of research.

Betting on the best case: higher end warming is underrepresented in research
  1. We settled on Wagner and Weitzman because it is well known and also because they were kind enough to provide us with their data and code. It is indeed true that other probability curves might paint a more optimistic picture. However, the differences are so large that I would be surprised if it would change the conclusion of our paper.
  2. We looked at the complete IPCC reports, because we wanted to understand the overall focus of policy relevant research. But it is indeed true that the research gap differs between the working groups and the research gap is larger when it comes to the impact focused reports.

I would say that there are several promising research directions when it comes to higher end warming:

  1. Exploring in detail what the effects of higher end warming even are. E.g. what are the possible effects on crops, livestock, habitable zones for humans, but also the economy?
  2. How could we cope with such possibly massive changes? Are there precedents in history where we had to undergo such massive changes and did it work?
  3. Taking a deeper look into geo-engineering, especially the potentially very effective, but more out there approaches like e.g. Project Vesta

And those are just a few suggestions from the top of my head. Basically, it boils down to finding out what the effects might really be and how we could cope.

FJehn's Shortform

Knowledge is fractal. Every time I wander into a new field of knowledge I am fascinated that it has its own tales, language, heroes, secrets and traditions. However, it does not stop at this scale. Every field had its own subfields and again we find exactly the same thing. You could spend your whole life trying to understand a field and you would still be completely surprised by what you might find in its subfields if you venture out. And again you would just find more subfields of the subfield you started exploring. It seemingly never ends. I like this personally as it means I will never run out of fascinating thing to find, but I wonder how long humanity can continue to amass knowledge until we get lost in the depth of our own fractal. Or will we just find new ways to cope with that?

Linch's Shortform

This resonated with me a lot. Unfortunately, I do not have a quick fix. However, what seems to help at least a bit for me is seperating planning for a day and doing the work. Every workday the last thing I do (or try to do) is look at my calendar and to do lists and figure out what I should be doing the next day. By doing this I think I am better at assessing at what is important, as I do not have to do it at that moment. I only have to think of what my future self will be capable of doing. When the next day comes and future self turns into present self I find it really helpful to already having the work for the day planned for me. I do not have to think about what is important, I just do what past me decided. 

Not sure if this is just an obvious way to do this, but I thought it does not hurt to write it down.
