    I did not actually ascend the big stick. Highest tower I ever did was 100 meters in Panama. It was wobbly.

    It is usually impoverished slope dwellers that get killed by volcanoes. Volcanologists come in second. Disassembly of tourists is rare.

    Now if we can just get a blight resistant, American Chestnut tree.

    They planted some saplings here a few years back that are 1/16th Chinese chestnut. They should be resistant.

    Indoor air [CO2] could become high enough to impair cognition:

    Higher carbon dioxide levels could muddle our thinking

    Based on study presented at AGU and published on a preprint server. Note that neither has undergone journal-level peer review. But it merits some consideration.

    Your reporter adds that bottom-end CO2 sensors (non-dispersive infrared spectrometers) are reliable to within 30 ppm and cost about $70. Not very useful for research but good enough to know if your indoor air is too high. Adding also a thing that's been a burr under my saddle for a long time. Vehicles with very tight design and with airflow set to recirculate. Within such a small volume even one persons CO2 exhalation can have big effects. Some fella ought to make measurements. Single-vehicle fatal crashes where driver was alone and seems to have fallen asleep are not rare.

    Not engine related is what I'm talking about, so pure electric vehicles are not excluded. It's about that liter of 20% CO2 you exhale every minute.

    Newly published
    Burney JA (2020). The downstream air pollution impacts of the transition from coal to natural gas in the United States. Nature Sustainability https://doi.org/10.1038/s41893-019-0453-5

    From the Abstract:

    “Between 2005 and 2016 in the continental United States, decommissioning of a coal-fired unit was associated with reduced nearby pollution concentrations and subsequent reductions in mortality and increases in crop yield. In total during this period, the shutdown of coal-fired units saved an estimated 26,610 (5%–95% confidence intervals (CI), 2,725–49,680) lives and 570 million (249–878 million) bushels of corn, soybeans and wheat in their immediate vicinities; these estimates increase when pollution transport-related spillovers are included.”

    Some of the most enjoyable figures are in 'extended data' and not paywalled.

    There are other countries on similar paths where similar studies could be undertaken.

    Wuhan virus is shaking things up on this side of the world

    Wuhan, China, and 5 other cities have been quarantined as China attempts to halt the spread of the coronavirus. That's about 23 million people on lockdown.

    Will not now link to other info about this. But keep in mind that this is Spring Festival travel time in China, so the timing is unfortunate.

    Sleepy Kunming has one patient in isolation who happens to be in a hospital right across the street from my apartment. I am not inclined to provide photographic evidence :eek:
