I'm told that ``the great plains'' and several other biotopes actually
need or at least benefit and/or derive part of their character from
occasional fire.
You'll want to read that National Geographic article if you can find
it. Fires are beneficial, and there is plenty of documentation to this.
Not to endorse random idiots causing fires, of course, far from it. And
now that us humans live just about everywhere... *we* certainly object
to having our homes burnt down.
Again - the article. Some people are starting to believe that the
decision of the US Forest Service director in ~1910 to "banish" all
wild-fires (this after the fires of 1910 burned "millions of acres"
and killed dozens of firefighters with smoke drifting over New England)
set up this problem. A study of two patches of Arizona forest estimated
they contained about 50 trees per hectare in the late 1800s and after
nearly 100 years without fires, there were 1700 trees in the same area.
I learned to fly years ago in California, and one unofficial task that
was stressed was that if you see a fire and don't see indications that
the fire services are working it, you WILL report it via radio and the
FAA will forward the information to the state fire officials.
At a certain ex-WWII spitfire field[1] where I spent one or two summers
flying gliders the (movable) field shack contained a fire service radio
for exactly that purpose.
It's always been a problem here in the West. Because we've been trying
to stop all fires, we've generally got a lot of things on the ground to
burn - not just man made stuff.
I recognise one really wants that when it's habitually that hot. I
personally would rather do without if at all possible. Aircos cause me
dehydration which in turn causes nasty headaches that take days to
dispel even when I notice and then make sure I stay over-hydrated.
You don't want to be here. A few minutes ago, they reported the met
numbers, and the relative humidity was 18%. During the spring and
early summer, we _normally_ see single digit relative humidity numbers.
You know it's bad when it's 40C, but the dew point is below 0C.
The last time I ran into that headlong was when I forgot to turn the
airco back off after the cleaning crew had turned it on (*again*) in
the appartment we were staying for a vataction in Greece. Apparently
during a heatwave. I still preferred the heat, despite being ill-suited
for it otherwise.
Two answers - first being replacing (or supplementing) the air
conditioners with what we call 'swamp coolers" or humidifiers. We have
a total of five in the house now, though I'm only using two. The "big"
one holds 28 liters of water, and if I let it run 24/7 I need to refill
it twice a day. That's actually over-kill for this house, and makes it
to humid. There are also house coolers running on the same principle,
but you've got to exhaust the moist air about as fast as you are
creating it, lest the house turn into a rain-forest. The idea of the
swamp cooler is that the air comes out at _close_ to the dew point.
With 38C and 18%, that means the air comes out ~10C.
As far as hydrating, you might get the clue from the convenience stores
that sell cold drinks. The "small" is a half liter, and the largest
size is usually around 2 to 2.5 liters. When I'm working in the yard
this time of year, it's not at all unusual for me to consume 2 liters
per hour, and I'm taking breaks because even that much time doing
hard labor outside is to much. I keep 10 liters of water chilling in
the fridge just for this reason. For a 20 minute bicycle ride, I take
along 2 liters of chilled water (well, it's cold when I started).
If you're constructing in a habitually hot area, wouldn't it make more
sense to, oh, use really thick stone walls or construct underground or
something, instead of spending 20+ years of energy on an airco?
When the Spanish missionaries were working the West coast up to about
San Francisco, the mission churches they built were usually quite thick
walls. Underground might be OK, but you'd better hope the waterproofing
was done perfectly lest you be flooded out during a rate thunderstorm.
And only a really dumb tourist drives a car without air conditioning.
Quite a different situation from getting slightly undercooled during a
long trip sitting still in a slow car[4] with the airco set at 18C or
so (with 25C or so ambient. geez).
25C is a bit below what we cool things down to - it's 27C in this room
as I write this.
[1] 1200 metre and 800 metre grass strips, cross-wise, lots of woods
around[2]. Quite interesting landing when windy. Fantastic winch,
though.
We've got a lot of interesting.cn airfields - my favorite was a 760
meter runway at Santa Cruz. There are hills all over the place, and the
procedure was to fly the downwind about a half mile to the side at 330
meters above the runway. Passing the numbers, you pulled power to idle
dump full flaps, and made a medium steep turn, rolling out of the turn
over the numbers. That's about a 1:8 decent or about 7 degrees. There
was a hill about 150 meters above the runway about 800 meters out on
final which is why you pulled this stunt. Great confidence builder
for learning landings to a spot.
[4] Towing a glider in a not-entirely-suited trailer, so max 70km/h.
70 km/h... 43 mph - you'd better be on the side streets, or you'll get
run over by the herd.
