    Some love for bats has been posted at Sci Am"

    Bats Are Not Our Enemies - Scientific American Blog Network

    It's surely the case that humans and bats have managed to get along in the past. But more close interactions seem to present a lot of negatives.

    I did not know they pollinated mango, but other species do as well. For any tequila lovers reading, they are unique Agave pollinators.

    Also, concentrated solar is hot enough to make cement. Otherwise a very 'fossily' process.

    It seems that some of the carbon emission comes from that fossil heating, and some from the breakdown of calcium carbonate into useful material and CO2.

    How much CO2 reduction could we get from non-fossilizing the heat?

    I broadly agree with that. complications follow :)

    The mineral produced by cement + water has full capability to re-consume CO2 from 'the limestone half'. Called mineral carbonation (carbonation is one of those words that means way too many things).

    However, concrete does not readily or rapidly re-carbonate. Good thing since it would not make good buildings or bridges.

    But should one desire to knock down a building and make it powder and mix it with biologically active soil, it absorbs CO2. (an ongoing experiment by me). I did not knock down a building, but it is very common in China these days. Large national fleet of concrete has a short half life.

    My first ever complaint about the superb NWS doppler radar system :D Mostly because it might amuse.

    For >24 hrs, Phoenix area has apparently been having super duper floods

    NWS radar image from Phoenix, AZ

    But not, really. One imagines that the radar 'gain' knob got turned up way too high and nobody has noticed. Leading to speculation that somebody is slumped over their desk in Phoenix office.

    I hope not. And it is sure to be noticed, eventually.

    Hummmmm, they have a pestilence already. Perhaps God is sending a message about what is up next. <grins>

    Actually my brother George living in Tempe shared a weather forecast of that area with day after day of +100 F (+38 C) temperatures. It is more likely the equipment HVAC failed and too hot to go to the remote site.

    That humidity is rough!

    According to the radar image, the radar at that time was in "vcp215." More on vcp modes is available at NWS JetStream MAX - Doppler Radar Volume Coverage Patterns (VCPs)

    There are several radar modes available, most are automatically chosen by the radar software algorithms, although the radar vcp can be controlled/overridden manually.

    Not sure why the radar was in vcp215 since it's a precip scan. Maybe there were some isolated showers around, or at least the radar thought there were?
