Doomwatch, 15 July 2021

There’s lots of doom stalking the earth, but mostly of the “humans are their own worst enemy” variety. There is only one active tropical cyclone – Hurricane Felicia, off the west coast of Mexico and headed out into open water. The invest area in the Atlantic is nothing to worry about, probably just a bored forecaster. There is a more serious threat potentially developing in the West Pacific that some of the models forecast to be a major storm impacting Okinawa in four or five days before heading towards Mainland China. There has been bad flooding in Germany, and in the western US heat and wild fires continue to be a problem. And the usual scattering of earthquakes, including a swarm on the California/Nevada border, and a half dozen or so volcanoes spewing ash, but none causing significant damage. Here’s a map of natural doom:

In the “doing it to ourselves” category the SARS-COV-2 pandemic continues to do a slow burn through the population lacking natural or artificial (vaccinated) antibodies. It’s hard to get a solid handle on just how dangerous some of the new variants are. The majority of infections are now the notorious “Delta” variant (B.1.617.2 – here’s more about variants then you want to know). It does seem to have a much higher transmission rate – the variants making the rounds last year and this spring had an R of around 2, “Delta” is probably well over 3. What that means is that for the original virus, one person would infect on average two other people. “Delta” seems that one infected person can infect between 3 and 4 people. Of course that doesn’t tell you anything about the consequences of being infected – as we know, a lot of people are asymptomatic, others crash. The statistics don’t seem to indicate that conclusively, but the virus seems to be spreading within younger populations. Of course, that can be an artifact of testing bias, and that a lot of older people have had more of an opportunity to be vaccinated (or survived the virus). The research papers I’ve seen are mixed; some indicate that existing antibodies/vaccines aren’t as effective, some say it’s no big deal. The truth is probably both 😛 – there is some reduction, but it’s not increasing mortality.

The media is of course excited about Delta. For Chatham County, Georgia (Savannah Area) a reporter was breathlessly saying the community transmission index “doubled since the end of June!” Technically true, it has gone from 50 to 98 between June 30 and July 14, but let’s put that in perspective: In January it was over 600 … so while the trend isn’t great as “delta” moves into the area with both cases and CTI, this isn’t something to freak out over. If you have natural or artificial antibodies, you’re in good shape. If you don’t and are an adult, you should get vaccinated unless you have a solid health reason that makes it risky. It’s as safe as any other vaccines out there (which are pretty safe all things considered).

There are a lot of unsettling geopolitical developments that do not bode well for the upcoming weeks. The situation in South Africa is out of control. This has huge implications across southern Africa, as some of the logistics and food distribution facilities looted the last few days are essential not just in South Africa but across the region. There is unrest in Cuba – how much is natural, and how much astro-turf from Miami, and where it is going is debatable. Haiti continues to be in turmoil, and the web of involvement in President Moise continues to expand. NATO continues the risky game of “poke the bear”, conducting provocative exercises across the Black Sea at the risk of goading the somewhat unstable Ukrainian regime in to taking another action in Eastern Ukraine that will result in Russia being forced to respond.

But at least Brittany now has her own lawyer now, so that’s nice.
