[Climbing] (08/30/2020) Silent Running (5.10b, 7 pitches, Grade III) @ Darrington, WA

Route Details Mountain Project: Difficulty: 5.10b, 7 pitches, Grade III It was supposed to be a "nice, casual Saturday outing on a slab multipitch!" Well, only the "slab multipitch" part was true. For more details, read on..  Getting to the base of the climb... We left Seattle around 7AM! Driving to the TH took about 2 hours, where the last half hour was pretty gravelly on a dirt road. Our Suburu Forester did just fine though. Approach hike was short and pleasant at about 30 minutes. There were some impressive old growth trees en route!  Climb Details  There was a party in front of us, so we waited a bit and began around 11:00AM. We set our turnaround time to 4PM.  I led 5 pitches - 2, 3, 4, 6 and 7. The first pitch (which I followed) felt like a walk in the park - more like incline walking at about ~45-50 degrees. When we began on pitch 2 though, the steepness snuck on me pretty quickly. Suddenly I fou

Role of the discipline of Computer Science in Climate Modeling

Goals of this post 1. Understand why improving climate models matters for addressing climate change 2. Understand the role of computer science in the field of climate modeling What are climate models? Scientific models are representations of processes and systems; they can be mathematical, conceptual, or physical. They are useful in formulating and testing numerous hypotheses about the world and creating projections about the future state of the world. Numerical climate models are subsets of scientific models that mathematically describe the Earth's climate systems/processes, such as large-scale precipitation, the carbon cycle, atmospheric chemistry/aerosols, etc. They involve equations for climate variables (e.g. temperature, winds, ocean current..) that can be solved numerically on computers. Climate models range in complexity - from simple, idealized box models with mixing assumptions to complex ones such as global circulation models (GCMs) that simulate the Earth's atmosphe
