Kinder and Gentler?
I
don't want to bury the lead: it may "snow" next Tuesday. The atmosphere
will be shifting gears to a milder, March-like pattern as the storm
track lifts north. No guarantees, but I wouldn't retire the old snow
shovel just yet.
The GFS is hinting at 40s within 2 weeks, so
expect volatility and big weather swings in the weeks to come. Pretty
typical for March.
We all experience weather, not climate, which
makes it hard to notice the big trends. If I'm cold how can the planet
be warming? Or as John Oliver quipped: "I just ate so there must be no
global hunger." We live in our bubbles and rely on scientists to analyze
the big picture and remind us why it matters.
You may be
shivering, but 4 of the 5 smallest "winter cold pools" on record over
the Northern Hemisphere have been observed since 2004. And Minnesota is
one of the 5 fastest warming states in the USA. Winter temperatures here
have warmed at least 4F since 1970, according to Climate Central.
Details below.
Warmer air and oceans are increasing water
vapor; more fuel for major winter storms and excessive snows. Boston
just picked up 100 inches in about a month - 10 times more than average.
The statistical odds? 1-in-26,315. Good grief.

Boston's Astounding Month of Snow a 1-in-26,315 Year Occurrence.
100" in a month is pretty impressive, but it's off-the-charts-amazing
for Boston, where normal February snowfall is closer to 10". What are
the odds? Here's an excerpt of a good story from Eric Holthause at
The Washington Post: "...
To
do this, he parsed through every three-day period (to maintain
meteorological plausibility and prevent the possibility of
back-to-back-to-back 20-inch snowstorms) and then randomly generated a
set of hypothetical winters consistent with the city’s climate history.
His analysis shows that given a static climate, Boston can expect a
winter with a 30-day stretch like this one only once approximately every
26,315 years — 38 out of a million..."

Even As The Eastern U.S. Freezes, There's Less Cold Air In Winter Than Ever Before.
The winter cold pools are trending smaller over time over the Northern
Hemisphere, but they seem to be (consistently) setting up over the
eastern USA and eastern Canada as polar air becomes displaced south by a
rapidly warming Arctic. But temperatures aloft, about 1 mile above
surface level, show the trends. Here's an excerpt of a Jason Samenow
story at the
Washington Post's Capital Weather Gang: "...
In a study accepted for publication in the Journal of Climate,
Martin found that four of the five smallest Northern Hemisphere cold
pools on record — averaged over the winter — have occurred since 2004.
“Only 12 of the 43 winter seasons before 1990-1991 had below average
seasonally averaged areas whereas 20 of 24 winter seasons have had below
average seasonally averaged areas since,” the study says..."

Warming Winters: U.S. Temperature Trends.
We experience weather, not climate, which is one (of many) factors that
makes this issue so complex. If you're freezing your butt off how ON
EARTH can the atmosphere be warming? Not at my house! Keeping a global
perspective is difficult, but essential when discussing climate trends.
Here's an excerpt from
Climate Central focused on the rate of winter warming across the USA: "...
Since
1970, winters in the top 5 fastest-warming states — Minnesota, North
Dakota, Wisconsin, Vermont and South Dakota — heated up four-and-a-half
times faster than winters in the 5 slowest-warming states: Nevada,
California, Oregon, Colorado, and Washington. The five fastest-warming
states have seen at least 4oF warming in winters since 1970..."
Cold Bias Into Next Week.
The next thaw may not come until a week from tomorrow, based on the
latest guidance. Temperatures recover into the mid and upper 30s over
the weekend, pathetically reasonable I guess. The next chance of
accumulating snow (remember that?) is Tuesday, and it could be a few
inches, even enough to shovel and plow, depending on the final storm
track and how much moisture surges north. I'm going way out on a limb,
but there's a chance subzero lows late next week may be the last, or
among the last, of the winter season, based on the significant warming I
see for mid and late March.
Zonal Winds Aloft by Mid-March.
We'll see more cold fronts, but the odds of subzero nighttime lows
should drop off significantly within 2 weeks as winds at 500 mb (18,000
feet) blow from Vancouver, instead of Saskatoon. By mid-March much of
the Lower 48 will be easing into a more springlike pattern. Map:
GrADS:COLA/IGES.
Worth The Wait?
This has been a chilly February (8.5F colder than average, to date) but
temperatures may rebound just as quickly in March. An extended period
above freezing is forecast by the GFS after March 10 or so, even a few
days in the 40s to near 50F. Amazingly it may be warm enough aloft for
rain within 10-12 days.
Videographer Captures Elusive Green Flash at Sunset on Hawaii's North Shore.
I'm very jealous - I've looked for the green flash for the better part
of 40 years. Still no luck. Here's a story excerpt and video (proving it
does exist!) at
Huffington Post: "...
When
it comes to the green flash at sunset, people fall into one of two
camps: those who have seen it with their very eyes and swear by its
majesty, and those who say it's just a figment of our imagination. Hawaii-based videographer Eric Sterman
falls into the former, having recently caught the flash while making a
time-lapse video of the sunset on the north shore of Oahu..."

Tesla Gearing Up For Release of Batteries for the Home.
I have yet to meet (anyone) who doesn't like free stuff. That applies
to free energy, free electricity, harvesting the free power that hits
your home every day.
Gizmag has the details on how you'll soon be able to benefit from home solar panels and a well-positioned battery: "...
The
same lithium-ion battery technology that powers Tesla’s electric
vehicles will be used to develop a battery for the home, according to a
statement by CEO Elon Musk during a recent conference call with
analysts. The batteries would be used by homes and businesses to store
excess energy generated from solar panels during the day, and drawn from
at night when panels sit idle..."

The Robots Are Coming.
Is your job in danger of being disrupted by robotics in the
not-too-distant future? Here's an excerpt from a fascinating read at the
London Review of Books: "...
Frey
and Osborne’s conclusion is stark. In the next two decades, 47 per cent
of employment is ‘in the high-risk category’, meaning it is
‘potentially automatable’. Interestingly, though not especially
cheeringly, it is mainly less well-paid workers who are most at risk.
Recent decades have seen a polarisation in the job market, with
increased employment at the top and bottom of the pay distribution, and a
squeeze on middle incomes. ‘Rather than reducing the demand for
middle-income occupations, which has been the pattern over the past
decades, our model predicts that computerisation will mainly substitute
for low-skill and low-wage jobs in the near future..."

Climate Stories...
Yes, Global Warming Has Slowed Down A Little. And Yes, You Should Still Worry. Warming
of the oceans has accelerated, temperatures over land holding nearly
steady since the turn of the century. New research suggests any
land-based temperature plateau may be temporary; here's a snippet from
The Washington Post: "...
Ever
since, climate scientists have been trying to explain why the world has
seen a somewhat slower rate of warming in recent years — and publishing
multiple papers on the topic. Now, though, a new study in the journal Science suggests
that that the global warming “pause” may soon run its course, and,
anyway, it seems to have been caused by natural variability in the
climate system. Thus, the slowdown, such as it was, certainly is no
reason not to worry about a longer-term climate trend driven by
humanity’s greenhouse gas emissions..."

New Study Directly Measures Greenhouse Effect at Earth's Surface. Carbon Brief has the story and video; here's a clip: "...
The
researchers used a set of instruments to take thousands of measurements
at the Earth's surface. The instruments record the longwave energy that
is re-emitted by greenhouse gases back towards the Earth's surface,
which causes the warming. Making these sorts of measurements on the
ground is difficult, says lead author Dr Daniel Feldman,
a geological scientist at the Lawrence Berkeley National Laboratory in
the US. With weather systems passing overhead, and temperatures and
humidity changing frequently, it's tricky to take energy measurements
without other factors getting in the way..."

You Want Jobs? Try a Carbon Fee and Dividend. Here's an excerpt of an Op-Ed at
syracuse.com that resonated: "...
The proposal I'm talking about is George Shultz's Carbon Fee and Dividend.
Shultz, former Secretary of State under Ronald Reagan, promotes this
plan as the conservative answer to climate change, because it won't
increase the size of government. It works like this: A steadily rising
fee - starting at $15 per ton of carbon-dioxide - is placed on fossil
fuels at or near the first point of sale, increasing by $10 per ton of
CO2 each year. Revenue from the fee is divided up equally and returned
to all households..."
Climate Change Will Hit America in the Breadbasket. NBC News has the story - here's an excerpt: "...
Theoretically, reduced production along the southern edge of the country's grain-producing regions should be offset by increased production along the northern edge. The Corn Belt (and Soybean Belt) is already pushing up past the Canadian border,
and Canada's wheat-producing zone is creeping farther north. But in
reality, the shift is still likely to produce a net loss in crop
production, said Jerry Hatfield, director of the USDA-ARS National
Laboratory for Agriculture and the Environment..." (File photo: Star Tribune).
Sea Levels in Northeast Jumped 5 Inches In Just 2 Years, Study Says.
Some of this is sea level rise, some is land subsidence, but the net
effect is clear; higher water levels are making coastal storms even more
damaging, especially when you superimpose a storm surge and surface
waves on top of the rising Atlantic. Here's an excerpt from a story at
Mashable: "
Sea
levels in northeastern North America jumped by more than five inches in
a two-year period between 2009 to 2010, a rate unprecedented in the
history of tide gauge records, a new study found. The study,
published Tuesday in the journal Nature Communications, found that the
temporary acceleration in long-term sea level rise resulted in coastal
flooding and beach erosion along the Northeast coast from New York
northward to Atlantic Canada..."
