Heat Waves to Come

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*.

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?

Anybody know of cheap land in Alaska?  This will make Anchorage the fastest growing city in the nation at this rate.

There's lots of cheap land in British Columbia and Alberta, if you don't want to head all the way up to Alaska.

I've checked out all of the above in the past and as long as you don't insist in living in or right next to a big city, land can be CHEAP.

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.

What's the water table been doing?

Apart from the top few inches ground drying has more to do with water tables than humidity / temp / wind.

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.

3 to 5 degrees hotter

C or F?
