If the world is heating up a little, sometimes the extremes will
be more extreme, as in mega heatwaves. A new
research paper says that some of the recent past historical
heatwave incidents could become quite common, and reach even
higher sustained temperatures, way above any sort of danger zone
level for humans.
And it's not just at the end of the century. By 2050, heat
waves will be 3 to 5 degrees hotter than now "and probably
be longer-lasting," Sterl said...ed.z.: it is *already*
too hot.The past few years I have noticed the ground dries out
much sooner after rains than it used to (anecdotal non scientific
observation). I don't know why either, 80s and 90s and
cracking 100 are common temps here in the summer, just the ground
dries out faster. Seems too anyway. I find it *odd*.
I second your anecdote about ground drying although I thought it
was particular to the landscape at my current dwelling.
We're just below the foothills of small mountains (locally,
the mounts are called "hills" and we're between
those and the "flats" which abut the bay).
In lieu of much of soil, we're on bedrock maybe 6-10ft down
with almost-entirely-clay twixt there and surface. Top few
inches, back when they were feral, were soil. Since that got tore
out to lay down sod, it's grim.
I do most of the watering around here. (Not for much longer,
since we're moving, but for four years). Just even over that
scant four years shit has changed. Partly its because of the lost
weeds, replaced with dumb sod. In other parts, that variable is
controlled for and shit has still changed.
My take from watching it is that stuff has dried out from low
rain and higher temps and the clay layer has cracked. The net
effect is that we can dump a swimming pool of H2O on the ground
and, just about as fast is we do that it drains down to the
bedrock / modest water table. We live on a big drain.
Given the drought in your area, I would wonder if it isn't
similar. Stuff dries out and suddenly water just sinks way deep a
lot faster.
The alternative / complementary hypothesis is atmospheric change.
We agreed, some threads ago, about qualitative changes in the
sunlight. The spectrum changes might have something to do with
more efficient evaporation, too.
We're back up to entire 10s of bees, by the way. No shortage
of one's that show up and die but a larger number than the
worst days of live ones (and still about x10 short of what they
should be).
There's just too many details like this. Water, bees,
weather, etc. S has hit fan. Revolution NOW. Blast out the
clangstons. Nevermind technocratic BS theories about how the next
20 years go -- we're here now. This is it. She's dying.
Well, past two years has been more drought than not. I think the
previous Georgia record was around 5 years running bad drought,
so we'll see how it goes. This spring and now early summer we
have been getting more rain than last summer, but not that much
more and when it does rain the quantity isn't there, although
destructive winds seem higher. The trees still show mass stress
and frequently shed what look to be stout, non rotten big
branches, which is really weird. The leaves all seem smaller than
they should be. so ya, probably the sub surface moisture is way
down. I caught a whiff of sulphur in the well water last summer
and went UH OH PANIC CITY time and told gf to just cease watering
most of the outside garden, I don't want my sweet water to go
nasty. If it gets real bad we'll switch to almost all
container gardening. Lucky us we have a greenhouse for a real
good fall back. Greenhouses have their own problems, but you
certainly can control the water supply situation easier.

Not at the journal yet, but I found a draft of the paper at the university, here is the abstract, look for the link to the PDF: When can we expect extremely high surface temperatures?
