“One of the most interesting things about the MIP ensembles is that the mean of all the models generally has higher skill than any individual model.” We hold these truths to be self-evident, that all models are created equal, that … Continue reading

Sustainable Landscaping
Update: 2018-05-26 It’s not about plants, not entirely. But it seems that, in one agricultural area, pollinators (bees) under stress have ceded their pollinating responsibility to a couple of species of exotic (read invasive) flies. See: J. R. Stavert, D. … Continue reading

The work of Alec Bogdanoff and Carol Anne Clayson on the ocean surface boundary layer
Drs Carol Anne Clayson and Alec Bogdanoff examined evaporation from the ocean surface and energy exchange at the boundary layer of the ocean surface, respectively. See also the interactive illustration here. (The above is from Dr Carol Anne Clayson’s personal … Continue reading

Results of short literature search on impacts of climate change upon ecosystems and bird or animal migration patterns, from the journals of the Ecological Society of America
I decided to do a quick literature search on the impacts of climate change upon ecosystems and migration patterns. I could have kept the list private, but why not make it public? Not all these articles are purely about the … Continue reading

A model of an electrical grid: A vision
Many people seem to view the electrical grid of the future being much like the present one. I think a lot about networks, because of my job. And I especially think a lot about network topologies, although primarily concerning the … Continue reading

“Catching long tail distribution” (Ted Dunning)
One of the best presentations on what can happen if someone takes a naive approach to network data. It also highlights what is, to my mind, the greatly underappreciated t-distribution, which is typically only used in connection with frequentist Student … Continue reading
HadCRUT4 and GISTEMP series filtered and estimated with simple RTS model

p-values and hypothesis tests: the Bayesian(s) rule

Phytoplankton-delineated oceanic eddies near Antarctica

That two degree limit is closer than it appears
The UNFCCC’s COP21 concluded goals which aimed for limiting global warming to C, and certainly keeping it below C, both measured with respect to pre-industrial temperatures. Bad news. According to the United States National Center for Atmospheric Research (“NCAR”), in … Continue reading
