Caution: Driver Rueing
Lou thought Jane was getting too old to regard her
bitterness as the natural effect of a cause outside herself.
Annie Dillard, The Maytreees
Dammit, Lou!

When is a Beer Not a Beer?
"Glass of the
Berlinerweisse, please," he says.
"You drink that
stuff?" asks the hanger-on, curling a hand protectively around his Coke.
"Man, you don't want to do that! It's full of alcohol!"
Manfred grins at him
toothily. "Ya gotta keep your yeast intake up: There are lots of
neurotransmitter precursors in this shit, phenylalanine and glutamate."
"But I thought that was
a beer you were ordering ..."
- Charles Stross, Accelerando
I once thought the most
difficult decision I ever made was when I decided whether to try harder or to
walk away.
Some days – like today - a beer is not just a beer. The hardest
decision I made today was whether to wake up when my kitty slid off my side and
kissed me good morning with her whiskers or to roll over and take another hour
or so.
Today I was in the middle of
those extremes for the simple reason that the store closest to me doesn’t have
those fresh prepared meals in a cooler next to the golden rotating kiosk of
small lemon- and barbequed chickens. I decided to find my holy grail of steak:
prime (not choice) rib. Which is just a metaphor for how my life is an ongoing
circus of disappointment. You can only get choice cuts in generic grocery
chains. Why do I keep forgetting that and going through the pain over and over?
I ended up with some Bread
& Cie seedy whole grain bread, and almost got some quinoa crackers with
walnuts and cranberries but came to my senses. Also, and totally offsetting the
fact that I forgot cream cheese, I did score a memorable picture. It was not a
hard decision to continue my search for inspiration. I chose to pass on deciding
whether to unravel the mystery of meat. As Dr. Who said, humanity is just nature’s way of keeping meat fresh.
Sometimes meat is just meat. Instead of buying the strangely-coloured (sic) mystery meat I decided instead to have a
beer for dinner with my grilled cheese and tomato sandwich, side of home made dill
pickles.

Stern Lessons
The scarlet letter was her
passport into regions where other women dared not to tread. Shame, Despair,
Solitude! These had been her teachers—stern and wild ones—and they had made her
strong, but taught her much amiss.
- Nathaniel Hawthorne, The Scarlet Letter
I do not consider this
un-chosen journey as one where other women dare not tread.
Shame and despair
are part of the deal and nobody needs a passport to those regions.
If we learn
the lessons aright, we gain wisdom. Such as learning the difference between
surrendering and dying.
I do not consider solitude a
stern wild teacher that has taught me anything amiss. In fact, I find comfort
in solitude.
Every season, I change the things on the shelves in my front
window. I just put summer in.
Notice there is a cat in each picture. They have
taught me the difference between solitude and loneliness.

Water Wars are Coming
I chatter, chatter, as I flow
To join the brimming river,
For men may come and men may go,
But I go on for ever.
Maybe Not
Last year, for the first time, the amount of water
transferred from Lake Powell to Lake Mead was reduced, by enough to supply
about 1.5m homes. If the snowpack on the Rockies is as bad as Davis fears, then
there is likely to be a deeper cut in the coming months under a series of
agreements which allocate water rights.
The original agreement, the Colorado
River Compact, carved out nearly a century ago, divides the river’s
water between the states that rely on it. With hindsight, it sowed the seeds of
some of today’s problems. It failed to foresee the rapid rise in population in
the desert states of Nevada and Arizona, and the demands of their cities and
farms. Nevada, for instance, was allocated only 2% of total of the water
distribution.
The compact was also premised on predictions of snow packs
on the Rockies which some environmentalists have concluded were based on a
period of abnormally high rains in the west during the first quarter of the
20th century.
The agreement gives some states greater claim than others
when the water runs short. Arizona loses
out, except for a county next to the Mexican border which has what are
known as “senior rights” because it produces much of the US vegetable crop in
winter. Nevada
also does badly. The big winner is
California, which gets to keep its much larger allocation, for a while, at
least.
That state of affairs can be traced back nearly half a
century to construction of the largest aqueduct system in the US to deliver the
Colorado’s water to central and southern Arizona. The canals of the Central
Arizona Project (CAP) provide water to cities such as Tucson and Phoenix, and
irrigate close to 400,000 hectares (1m acres) of farmland. Without it, Arizona
would be less fertile and, probably, less inhabited.
But the CAP required the support of California’s members of
Congress to win funding and they exacted a price – if the water is rationed,
Arizona’s allocation is cut by half before California takes any hit at all.
In 2007, seven years into the present drought, new
allocations were signed by the US secretary of the interior in case the water
shortages grew. The cutbacks to the states kicks in if Lake Mead falls below
1,075ft.
In April of this year it was just 4ft short of that
benchmark as it fell to its lowest level since 1937, when the lake was still
being filled. If the water levels continue to drop, Arizona and Nevada will
face immediate cuts, escalating as the lake falls further.
That would threaten cities such as Las Vegas and the very
existence farms fed by the Arizona aqueduct. If the lake sinks below 1,000ft,
the water intake pipes would start sucking air. The Hoover Dam power turbines
would also stop spinning, interrupting an important source of electricity to
the region.
Davis said it’s a prospect that kicked state governments
into gear.
“We signed these guidelines in 2007, so all of the states
have been very proactive in storing groundwater, implementing conservation
measures, using recycling technologies. They have seen this coming,” she said.
Nevada is recycling most of the water used by residents and
tourists in Las Vegas. The Southern Nevada Water Authority put in
place a conservation plan that includes limiting the size of lawns,
restrictions on watering gardens and campaigns to shorten the time spent in showers
or running dishwashers. The authority says it has reduced demand from about 314
gallons per person per day in 2002 to about 205 gallons per day last year, and
saved 32bn gallons of water despite the region’s population rising by more than
500,000 people.
How the west was lost
The Colorado River Basin is the water lifeline of the
western United States. It provides water to roughly 40 million people in
7 states and to Mexico. It supplies water to major metropolitan
regions including several of the country’s largest and driest — Los Angeles,
San Diego, Phoenix and Las Vegas — and enough water to support irrigation on 4
million acres of farmland. As the water future of the Colorado River
Basin goes, so does that of the west.
In our new study, we used NASA satellites to find
that between December 2004 and November 2013, the Colorado River Basin lost a
total of 65 cubic kilometers of water, or roughly the equivalent of two full
Lake Meads. This was a period of prolonged drought in which the water
levels in Lake Mead and Lake Powell (the United States’ second largest
reservoir) had fallen to dangerously low levels, and were being carefully
managed to prevent further declines. Surprisingly, we found that 75% of the
water lost was from the Basin’s groundwater supplies.

Abstract
– Groundwater depletion
Streamflow of the Colorado River Basin is the most
overallocated in the world. Recent assessment indicates that demand for this
renewable resource will soon outstrip supply, suggesting that limited
groundwater reserves will play an increasingly important role in meeting future
water needs. Here we analyze 9 years (December 2004 to November 2013) of
observations from the NASA Gravity Recovery and Climate Experiment mission and
find that during this period of sustained drought, groundwater accounted for
50.1 km3 of the total 64.8 km3 of freshwater loss. The rapid rate of depletion
of groundwater storage (−5.6 ± 0.4 km3 yr−1) far exceeded the rate of depletion
of Lake Powell and Lake Mead. Results indicate that groundwater may comprise a
far greater fraction of Basin water use than previously recognized, in particular
during drought, and that its disappearance may threaten the long-term ability
to meet future allocations to the seven Basin states.
