There are usually several blog articles in various states of progress that need feedback and are being actively discussed in the forum before being posted to the blog. You can find them here. For an index of all blog articles that have been published, see Azimuth blog overview.
If you want to write a blog article on this wiki, go ahead! But there are some stylistic and formatting issues you need to think about. So, please start by reading How to blog.

Wiki page: Blog - warming slowdown? (part 1)
Status: published.
Summary: Is there something missing in the recent climate temperature record? Variability in the Earth climate observational record makes definitive determinations of warming difficult to establish, at least as determined by changes in mean global surface temperature. This recapitulates some of the history of the problem and its present status, focusing upon oceanic capture of heat, and addressing some of the technical discussion in the literature interpreting present trends. The problem is assessed from the perspective of the statistics of time series.

Forum discussion group: Invasion fitness in moment-closure treatments
Status: work in progress.
Summary: Moment closures are a way of forgetting information about a system in a controlled fashion, in the hope that an incomplete, fairly heavily “coarse-grained” picture of the system will still be useful in figuring out what will happen to it. Sometimes, this is a justifiable hope, but in other cases, we are right to wonder whether all the algebra it generates actually leads us to any insights. Here, we’ll be concerned with a particular application of this technology: studying the vulnerability of an ecosystem to invasion. We shall find expressions for invasion fitness, the expected relative growth rate of an initially-rare species or variety.

Summary: Introduces the concept of stochastic Petri nets. Starts with a general discussion of reaction network dynamics, followed by an exposition of the mass action kinetics (and its limitations).

Summary: Critics of climate science in general, and sceptics of the statement that anthropogenic (man-made) global warming is real, often claim that climate models are wrong and cannot be trusted. But what does “wrong” mean here and what can and should be done to make models more trustworthy, from a software engineering viewpoint? In a first step, we’ll introduce some relevant technobabble.

Summary: A brief but systematic exploration of various types of networks, and how they’re really all the same. Starting with a simple reaction network and corresponding Petri net, I demonstrate how to transform these into systems biology networks, systems of differential equations, Unified Modeling Language (UML) diagrams, mind maps, agent based models, and more. Along the way I introduce third-party tools that are able to process each of the resulting formats. This first part restricts itself to the transformation to differential equations.
