I had a pal share this at CFI, I can't watch it now, but thought I'd pass it along.  Looked pretty interesting.

Engineering the Software for Understanding Climate Change

Climate scientists build large, complex simulations with little or no software engineering training, and do not readily adopt the latest software engineering tools and techniques. In this paper, we describe an ethnographic study of the culture and practices of climate scientists at the Met Office Hadley Centre.

The study examined how the scientists think about software correctness, how they prioritize requirements, and how they develop a shared understanding of their models. The findings show that climate scientists have developed customized techniques for verification and validation that are tightly integrated into their approach to scientific research.

Their software practices share many features of both agile and open source projects, in that they rely on self-organisation of the teams, extensive use of informal communication channels, and developers who are also users and domain experts. These comparisons offer insights into why such practices work.

• Citizen, thank you for the tip. An interesting talk. The middle is somewhat technical, but the beginning is highly useful for everyone who wants to understand climate modelling.
• Thanks for this, CC. I've already got a couple of Steve's videos/presentations on the Wiki pages about climate models (here and here). I'll add this one as well.
