Agents In Society

If you had a super-intelligent General Artificial Intelligence and you asked it to produce as many paperclips as possible, the results could be catastrophic. It could destroy the Earth in search of the goal of optimising the manufacture of paperclips. This is an often used analogy designed to illustrate the dangers of poorly defined goals in artificial intelligence (AI) and machine learning (ML). However this paradigm of analysis has wider utility in consideration of society.

The Fast Transition

In May 2015 I concluded a series of posts with The Slow Transition. It was a risky prognostication but an additional 7 years of data has supported what I said back then: That the transition to a seasonally sea ice free state would be slow, not fast, as some argued. This post is about the period preceding that, and with the further 7 years of data something substantive can be said about that.

The Arctic Ocean's sea-ice has undergone a fast transition from one stable mode to another equally stable mode. Between those modes there was a bifurcation driven by the power of an increase of Open Water Formation Efficiency and Ice Albedo Feedback. That bifurcation happened between 2002 and 2006, with the 2007 stochastic event delivering the coup-de-grace that finalised the bifurcation event.

Attractors, Critical Slowing, and Bifurcations

In this post I want to introduce some ideas of system level analysis connected to attractors and bifurcation.

Open Water Formation Efficiency Part 4

Open Water Formation Efficiency (OWFE) is a measure of the ease with which melt season thinning of sea-ice reveals open water. In March I published a post looking at how this operates from a theoretical perspective. In this post I look at how it operates in practice in various regions of the Arctic Ocean.

Ukraine: We cannot risk nuclear war.

Russia, the enemy, is afoot in Ukraine, yet The West demurs to engage properly, preferring instead to wage a proxy war. In this stance the West and NATO show themselves to be weak and effete, worse than this, The West has the blood of Russian atrocities against Ukrainian civilians on its hands.

The BCE Region Killzone

The BCE region is comprised of the Beaufort, Chukchi, East Siberian Seas. Due to the Beaufort Gyre it has a special role in the dynamics of Arctic sea ice.

Ukraine Aeronautical

Just a few things of note from Ukraine on the aeronautical side of things. Images from my account on Airnav Radar Box which is cheap and (for me) very useful, I can recommend it highly.
