    Summer 2019 Banter Thread

    The Conservancy runs the Park, because they provide over 75% of the money. So they set the priorities, which are to make the Park as attractive to everyone as possible. That means mosquitoes and biting flies are unwanted, as are caterpillars dangling from the trees. Unfortunately, the cheapest way to fight such 'pests' are broad spectrum insecticides, so there is a lot of collateral damage. Not sure how to fix this. Ideally, the Conservancy would add a priority for natural habitat preservation, with success measured by the number of breeding species rather than only the number of human visitors.

    Lucky you! Here in NYC Central Park, we rejoice when we see a few Monarchs and Red Admirals. Diligent pest control spraying pretty much kills everything, although I'm delighted to note the fireflies this year are numerous. Long may they all flourish!
  3. There is logic in the decision to retain the Central Park benchmark. The aim is to report the weather rather than to measure urban heat island effects. I have no doubt that the concrete jungles we live in are hotter than the relatively green acres of Central Park, but that does not make the Central park data 'flawed'.
  4. Then you remember to add the lightning protection and pretty soon you need an electrician. Roof tripods are not that simple.

    Arctic Sea Ice Extent, Area, and Volume

    Perhaps the difference reflects definitional parameters? One is Arctic Basin only, the other possibly the AMSR2 total area? Hard to discuss when the data is inconsistent. Just seems that Arctic ice is a topic where every detail has to be agreed, is it area, is it extent, is it volume, what coverage percent is included, are the land masks constant etc etc.

    They hatch when it rains a lot.

    Prepare to be disappointed. Very few really dedicated suppliers have survived the wave of cheaper imports. I don't know whom I would trust to deliver a reliable system today.

    Arctic Sea Ice Extent, Area, and Volume

    Have to say that the data strongly suggests a declining trend for arctic ice. Possibly this is a cyclical phenomenon, which will reverse at some future date. Historical records from the 1920s suggest a similar warm cycle has been seen before. Nevertheless, absent any identifiable mechanism to reverse the current warming, it seems reasonable to expect the 2012 lows will be broken, possibly this year. Forkyfork makes a very strong argument that the recent increase in extent reflects fragmentation of previously solid ice pack, which sets the stage for enhanced melting of the shattered ice. With the maximum melt still more than 2 months away, the odds are shifting towards a new record low imho.
  9. They do gradually lose charge over time, but they should recharge properly once plugged in. The recharge process is not 100% efficient, so the issue is more the number of recharges than the time since manufactured.

    South East Arizona would bring it all back for you. In fact, there is a whole astronomy community near the Chiricahuas, along the road to Portal, with many homes built around observatories. No lights, no clouds, just you and the stars in the desert.

    Au contraire! A consensus prediction is pretty worthless, we make progress when things go different from what everyone expects and we reappraise. Of course it is always easier to burn the deniers at a stake....

    Nature still does not care. A real life experience. Glad no one got hurt!

    Not a gardener, but the Goog suggests verbena, marigold and geraniums.

    That's why we have federally subsidized flood insurance, can't have dumb nature interfere with our right to build anywhere we want to...
  15. Battery replacement is straightforward and explained in the user manual, with illustrations, so you will have no trouble. Do note that this unit takes 2 batteries, model RB1290A. It is good practice to replace them both together, that way there is not one stronger than the other. The user manual, actually more like the user sheet, is here: https://dl4jz3rbrsfum.cloudfront.net/documents/CyberPower_UM_CP1000AVRLCD.pdf
