Meteorologist Paul Douglas writes about Minnesota weather daily, trying to go beyond the "highs" and "lows" of the weather story to discuss current trends and some of the how's and why's of meteorology. Rarely is our weather dull - every day is a new forecast challenge. Why is the weather doing what it's doing? Is climate change a real concern, and if so, how will my family be affected? Climate is flavoring all weather now, and I'll include links to timely stories that resonate with me.

More March Than April Into Monday - Slushy Possibiliies - TV Meteorologists More Likely to Talk About Climate Change
.38" rain fell yesterday at KMSP. 47 F. high temperature yesterday in the Twin Cities. 63 F. average high on April 26. 49 F. high on April 26, 2016.
April 27, 2002:
Heavy snow falls over the Twin Cities and central Minnesota. Chanhassen
receives 6 inches, and vivid lightning is seen with the snow during the
evening. April 27, 1996: Embarrass records a low of 9 degrees. Some central, and most northern, Minnesota lakes are still ice-covered. April 27, 1921: A late season blizzard hits Hibbing. The temperature was 75 degrees three days earlier.
It's Chilly, But At Least It's a "Dry Chilly"
The
coldest I've felt was not in Minnesota. Not even close. Manhattan,
surrounded by water, can be bone-chilling. But the most painful walk was
on Michigan Avenue in Chicago, pushed along by 40 mph winds, high
humidity allowing the cold to slice right through my coat.
We all
get grief for putting up with Minnesota's manic weather, but at least
the sun is out and humidity levels are low. That is not the case in
Milwaukee, Chicago, Detroit & Cleveland, where lake effect means
more cloudiness and higher humidity, which conducts the cold much
faster. 32F in Chicago FEELS colder than 32F in St. Paul.
We're
paying a steep price for last weekend's warmth; I was hoping not to say
the s-word again. Keep in mind July is the only month where snow hasn't
been observed somewhere in the great state of Minnesota. Insert sinister
laugh track here.
Lumpy stratus clouds linger today, but cool
sunshine returns Friday and Saturday, the nicer day of the weekend.
Models hint at a slow-moving southern storm pushing heavy rain into town
Sunday, maybe ending as slushy snow Monday.
60s return the following weekend - this too shall pass!

Flood Potential for Nation's Midsection.
NOAA models print out as much as 7-8" of rain over the next week over
the Middle Mississippi Valley and Ohio Valley as a series of storms pull
Gulf moisture northward. Expect more flood watches and warnings in the
coming days. More March Than April.
The stroll into spring is more of a drunken stagger; always two steps
forward - one step back. Today a storm over the Midwest brushes
Wisconsin with a mix of rain, ice and snow, while a band of heavy
T-showers pushes into the eastern U.S. Showery rains linger across the
Pacific Northwest with more snow for the high terrain of the
intermountain west. The next storm spins up over the southern Plains
Friday, pushing north over the weekend with a broad shield of rain, ice
and snow. 84-hour NAM guidance: NOAA and tropicaltidbits.com. Winter Relapse.
Models hint at a plowable snowfall across parts of Wisconsin and the
U.P. of Michigan today; skiers still deliriously happy in the Rockies as
the snow machine just doesn't want to let up. It would be premature to
pack up the heavy jackets over the northern third of the USA anytime
soon.
Wintry Cheap-Shot, Then Springy Late Next Week.
The next week or so won't be terribly pleasant, but the beauty of snow
in late April? It can't stick around - not for long. A high sun angle
prevents that, even on a cloudy day enough infrared radiation will
penetrate a cloud deck to melt snow. A slushy coating is possible this
morning, again Monday before temperatures move in the right direction.
ECMWF data: WeatherBell.
Warming Trend Second Week of May.
On-again, off-again spring looks on-again for most of the USA within 2
weeks as a weak zonal flow returns with warmer temperatures for most of
the USA, with the possible exception of New England.
What's the Arctic Doing to Midlatitude Weather, and Vice Versa?
What happens in the Arctic doesn't stay in the Arctic. Rapid melting
and historic warming may already be impacting jet stream wind speeds and
amplitude over the Northern Hemisphere. Here's an excerpt of a post
from Bob Henson at Category 6, courtesy of Weather Underground: "...One
thing that’s clear from the meeting is that Arctic-midlatitude linkage
is no longer a topic easily dismissed, if indeed it ever was. As
human-produced greenhouse gases heat up the planet, high latitudes have
been warming more than twice as quickly than midlatitudes and the
tropics. This phenomenon, known as Arctic amplification (AA), has been
well predicted by models. There’s also been a dramatic decrease in sea
ice extent across the Arctic, with the peak loss areas shifting in
location from winter to winter but often showing up in the seas north of
Eurasia, including the Barents and Kara. These trends were more obvious
than ever this past winter, as Arctic surface temperatures smashed records and sea ice extent hit its lowest yearly maximum on record.
But do scientists have a solid handle on how AA itself operates? That’s
one of several basic questions that made their way into the workshop
discussion. After all, heat can get into the Arctic atmosphere in a
variety of ways..."

temperatures during winter (Dec – Feb) showed an increasing trend across
the Arctic Ocean and most of Canada from 1989 to 2016, but they dropped
markedly across most of northern Asia, with minor decreases over the

Remembering the "Super-Outbreak" of April, 2011. U.S. Tornadoes recaps those fateful, deadly days in late April, 6 years ago: "Some
350 or so tornadoes — roughly 25 percent of which were strong/violent —
scarred the landscape from April 25-28, 2011, in what has been dubbed
the Super Outbreak of 2011. There were 321 people killed during this
period, with 316 of those deaths coming on April 27 alone. On April 27,
15 violent tornadoes
rated EF-4 or higher (including four EF-5s) struck the states of
Mississippi, Alabama, Tennessee and Georgia. Alabama was the hardest
hit, with 9 violent tornadoes touching down there, and 11 total crossing
within its boundaries. The top two deadliest tornadoes in April since modern records began hit that day. It was well advertised that an event of an unusual magnitude was on its way, with forecasters and hobbyists taking notice about a week out, and the alarm growing stronger by the day..."

Why 1-Hour Lead Time May Be "Too Much" for a Tornado Warning.
Because the warning may lack the same sense of urgency, because people
may be tempted to drive to a 'safer' part of the county, with resulting
traffic jams. Dr. Marshall Shepherd takes a closer look at Forbes: "...The
survey revealed that the average preferred lead time was about 34.3
minutes. This is interesting because it means that we do have some work
to do in order to get to the "sweet spot" the public wants. It is also
interesting because respondents indicate that lead times in the 1 hour
range may make them less likely to respond with the same sense of
urgency. Dr. Gina Eosco, a Risk Communication Expert at Eastern Research Group, told me by direct message
The
utility of it depends on the context. Hospitals will use it.
Forecasters will use it. But the average person? My fear is they will
find something else to do. I don’t see anyone sitting in a shelter for
an hour. Perhaps we’re thinking about the purpose all wrong though. A
one hour heads up may spark awareness and more attention to the 10
minute warning....”
Worst Flooding Since Hurricane Matthew Swamps North Carolina.USA TODAY has a good summary of the weather headaches in the Raleigh/Durham area: "People
in North Carolina are paying attention to rising rivers after storms
dumped several inches of rain across much of the state. Gov. Roy Cooper
warned residents on Tuesday to stay wary after the state's heaviest
rainfall since last year's Hurricane Matthew. State emergency management
officials are warning of possible flooding along the Neuse River near
Clayton and Smithfield, and the Tar River in Tarboro and Greenville. The
rain caused disruptions to the morning rush hour, and several motorists
also had to be rescued from their cars, according to ABC 11. Flood warnings were posted for rivers in 33 eastern counties..."
The Climate Context for Raleigh's Rains and Florida's Fires. Here's perspective from Andrea Thompson at WXshift: "...The number of heavy events has continued to be well above average over the last couple of years, maintaining the upward trend,” Ken Kunkel, a climate scientist with the North Carolina Institute for Climate Studies and N.C. State University, said in an email. A Climate Central analysis
shows that by mid-century, heavy runoff from rain-driven inland
flooding will increase between 20 and 40 percent. Of course, climate
change isn’t the only thing that impacts flooding, as the built
environment, such as impermeable pavement, exacerbates flooding in urban
areas like Raleigh. While this area of North Carolina has seen about 400 percent
of what would normally fall over the past two weeks, mostly from this
storm, much of Florida has been left thirsting for storms to quench the
dry conditions that are helping to fuel wildfires. The blazes have
burned the largest area of the state since 2011, some 115,000 acres, and will likely cost millions of dollars in damage and fire fighting costs..."
The Impact of Weather on Auto Insurance Costs. A story at Yahoo Finance had a few nuggets I wasn't aware of: "...When
it comes to weather and auto insurance, there are several
misconceptions. In many cases, auto insurance policies have nothing to
do with the weather in an area because they simply do not reimburse for
damages caused by tornadoes, flooding and extreme weather in general.
Winter does not make auto insurance more expensive! A common
misconception that many drivers have involves snowy weather and auto
insurance. Many believe that during the winter months, prices go up due
to the worsening driving conditions. However, this is not true. In fact,
across the United states, December is the cheapest month to buy auto
insurance in..."
Today's Energy Jobs Are In Solar, Not Coal. Here's an excerpt from The New York Times: "...Last
year, the solar industry employed many more Americans than coal, while
wind power topped 100,000 jobs. Those numbers come from a Department of Energy report
published in January by the Obama administration that provides the most
complete picture available of American energy employment. In 2016, 1.9
million Americans were employed in electric power generation, mining and
other fuel extraction activities, according to the report – a field
we’ll call power creation for short. More than 373,000 Americans worked
part or full time in solar energy, and just over 260,000 of them – or
about 70 percent – spent a majority of their time on solar projects..."
Scientists Have Discovered a Worm That Eats Plastic Bags and Leaves Behind Antifreeze. Quartz has the story: "The
wax worm, a caterpillar typically used for fishing bait and known for
damaging beehives by eating their wax comb, has now been observed
munching on a different material: plastic bags. Scientist Federica
Bertocchini of the Institute of Biomedicine and Biotechnology of
Cantabria in Spain first noticed the wax worms’ plastic-eating skills
when she was cleaning up a wax worm infestation in one of the beehives
she keeps at home. She put the worms in a plastic bag, tied it closed,
and put the bag in a room of her house while she finished cleaning the
hive. When she returned to the room, “they were everywhere,” Bertocchini
said in a statement. They’d escaped by chewing their way out of the bag, and fast..."

The Electric-Car Boom is So Real Even Oil Companies Say It's Coming. Here's a clip from Bloomberg: "Electric cars are coming fast -- and that’s not just the opinion of carmakers anymore. Total SA,
one of the world’s biggest oil producers, is now saying EVs may
constitute almost a third of new-car sales by the end of the next
decade. The surge in battery powered vehicles will cause demand for
oil-based fuels to peak in the 2030s, Total Chief Energy Economist Joel
Couse said at Bloomberg New Energy Finance’s conference in New York on
Tuesday. EVs will make up 15 percent to 30 percent of new vehicles by
2030, after which fuel “demand will flatten out,” Couse said. “Maybe
even decline...”

Charge Me Up: Rural Electric Car Drivers Face "Range Anxiety". Driving an older (2013) Tesla Model S with a range of 200 miles, I understand the concerns pointed out in a story at Telegraph Herald:
"...There are more than 18,000 electric car charging stations in the
United States, and the number of outlets at those stations has more than
tripled over five years to about 48,000, according to federal data. But
they often are few and far between in rural areas. That can leave
electric vehicle pioneers in the backcountry with chronic “range
anxiety,” the fear that their batteries will run out and leave them
stranded.
Science Under the Populist Gun. The author of the story at Scientific American warns that people who have trouble putting food on their table may not see the value of research and science: "...The
president promised his populist adherents he would bring jobs back by
restructuring trade deals, deporting undocumented workers and
eliminating federal regulations. But he’s almost certain to fail across
the board because technology is the real source of the job losses. And
it’s simply not possible for the president to decree a return to the
halcyon days of Middle Americana. The permanently displaced workers and
those that are on the cusp of dislocation might not blame President
Trump for failing to deliver on his promises, but they could direct
their populist, anti-elitist anger toward the architects of the
technological advances that have diminished their lives. As they see it,
the devils are big business that does not have their interests at
heart, big government that is too remote and dysfunctional, Wall Street
that hums tirelessly to further enrich the already wealthy and, finally,
the ivory towers of academia, which house the archetypal elites..."
The World May Begin to Do More But Consume Less. Here's an excerpt of a story at The Los Angeles Times that resonated: "...Sonenshein’s
basic argument is that our tendency to think of “more” as the key to
success –– as in more money and more stuff –– is all wrong. By always
seeking more, we tend to overlook the possibilities that already exist,
he says. When we focus instead on using the resources we have, we
stretch ourselves, thereby unlocking creativity and problem-solving
skills. It makes a lot of sense. And the more I’ve thought about this
idea, the more I have noticed variations of the doing-more-with-less
theme popping up all over..."
Is Singapore's "Miracle" Health Care System the Answer for America? Would Americans stand for a U.S. equivalent of "Medisave"? Here's an excerpt of a fascinating story at Vox: "...When
conservatives praise Singapore’s health system, they are typically
praising the Medisave system. Medisave is a forced savings plan that
consumes between 7 and 9.5 percent of a working Singaporean’s wages —
think of it like the Social Security payroll tax, if said tax funded a
health savings account. Singaporeans then pay for some routine care out
of their Medisave accounts. Conservatives like Medisave because it is
built on a deep appreciation for the idea that routine medical care can
be treated like any other good, and patients can be pushed to act like
consumers when buying it. Which is all true. Medisave distinguishes
Singapore’s system from that of the US or Western Europe, where insurers
typically cover most of the cost of routine care..."
Watch It While It Lasts: Our Golden Age of Television. Financial Times takes a look at why there's so much (amazingly good) television out there right now: "...We
used to complain that there was never anything good on TV. Now we
complain about the opposite. Spoilt for choice as we may be, we should
not forget to be astonished that an industry once regarded as an
artistic wasteland has turned itself into the world’s most prolific
source of new stories. Whether we are in the middle or nearing the end
of television’s golden age is hard to tell. Our sense of being
overwhelmed by new shows is not illusory. According to FX Networks
research, in 2016 there were 455 original series in TV, up from 182 in
2002. Yet we haven’t necessarily reached what John Landgraf has called
“peak TV”. “We’re not seeing any slowdown in the appetite for new
content, from all kinds of buyers,” says Laura Kennedy..."
Now THAT Was Music.
Why does new music (sometimes) get on our nerves? Hey, I'm a classic
rock guy, but I just discovered a new band I really like (The 1975), but
I have to agree with the premise of an article at Aeon: "...For
one thing, it doesn’t happen to everyone. Musicians seem particularly
immune, for obvious reasons, and so do certain types of journalists, for
reasons touched on in the paragraph above. Still, it’s a very real
phenomenon, as real as anything that transpires in the mind. Famously,
something similar happens to us with sports, particularly spectator
sports, and at a much younger age. But no one really feels too badly
about that, because of the inherent meaninglessness of watching other
humans engage in physical activity. It’s like ruing the day you ever
stopped liking porn. But music is different. Denounce the music of the
present day, and you’ve instantly become a walking, talking, (barely)
breathing cliché, ripe for ridicule, a classic figure of parody and
invective. It doesn’t happen to everyone, but it could certainly happen
to you..."

Sometimes, though, something really different shows up, and it takes the
combined efforts of citizen scientists over social media, and
scientists with access to specialized satellites in orbit, to figure it
out. This is what happened with a special kind of aurora feature, which
some have been calling 'Steve'. Here is 'Steve', shown in the image

Climate Stories....
How Climate Evangelists Are Taking Over Your Local Weather Forecast. Eric Roston at Bloomberg reports: "...This
American reluctance to embrace scientific evidence hasn’t often been
counteracted by broadcast meteorologists—who are, in fact, no more
likely than the average citizen to agree that climate change is caused
by humans. There are plenty of possible explanations for this outcome,
including a shortage of climatology education within meteorological
training programs. Part of meteorologists’ reluctance to talk about the
climate stems from the treacherous tools of their trade. Meteorologists
learn very quickly that weather models are messy. Some no doubt sour on
finicky climate models because of this experience. If short-term weather
models make mistakes, it may seem reasonable to assume that a model
projecting into the next century is ridiculous. “Meteorologists are used
to looking at models and being burned,” says Paul Douglas, a former TV
weatherman-turned-serial entrepreneur, who recently published a book on climate change and faith..."

U.S. Vulnerable to Worst of Extreme Sea Rise.
Keep in mind that the much-maligned climate models have done a fairly
good job predicting the warming that has already taken place, but if
anything these models have underestimated the rate of ice melt and sea
level rise. Here's an excerpt from Climate Central: "The
beginning of a collapse this century of sections of the Antarctic ice
sheet would disproportionately inundate coasts circling the U.S. — the
country that has done more than any other to pollute the climate. While
such a cataclysmic outcome of warming temperatures from greenhouse gas
pollution is considered unlikely, recent studies have shown it’s more
plausible than previously thought. Based on that research, the federal
government increased its worst-case scenario for the rise of the seas
worldwide by a quarter in January compared with 2014 findings, up to an
average of more than 8 feet by 2100. The impact would be even worse
around the U.S. A National Oceanic and Atmospheric Administration report
warned that regional effects of gravity and ocean current changes
triggered by the start of the ice sheet’s collapse could lead to more
than 12 feet of sea level rise engulfing some coastlines in the Lower
48. That’s about the height of a one-story house..."

Extreme Sea Level Rise and the Stakes for America. With more perspective here's an excerpt from Climate Central: "Should
a newly published sea level rise scenario come to pass, hundreds of
American landmarks, neighborhoods, towns and cities would be submerged
this century, at least in the absence of engineering massive, costly and
unprecedented defenses and relocating major infrastructure. Ocean
waters would cover land currently home to more than 12 million Americans
and $2 trillion in property. This extreme rise scenario, considered
unlikely but increasingly plausible, was published together with other
projections in a technical report
by the National and Oceanic Atmospheric Administration in January. NOAA
added “extreme” as a new sea level category in the publication,
supplementing high, intermediate and low categories that have also been
used in past reports. The new term reflects recent research suggesting
that some parts of the Antarctic ice sheet may begin to collapse much
sooner than scientists had previously anticipated, particularly if
ongoing emissions of heat-trapping gases like carbon dioxide and methane
remain high..."
80% of Heat Records Worldwide Linked to Climate Change. Increase the baseline temperature and extreme events become more common. Here's a clip at EcoWatch: "...Most scientific research examines the links between climate change and specific weather events, but a first-of-its-kind study
published Monday in the journal Proceedings of the Natural Academy of
Sciences used a new framework to take a comprehensive look at climate
measurements worldwide. The study found that over 80 percent of heat
records worldwide were linked to climate change, while climate change
influenced 57 percent of driest-year records and 41 percent of five-day
precipitation records..."
Most of the World's Largest Investors Taking Climate Risk Action. Bloomberg reports: "Most
of the world’s largest asset owners have gotten the message that
climate change poses a risk to their portfolios and are pivoting toward
greener investments. Funds worth $27 trillion that comprise 60 percent
of the world’s biggest investors are considering climate change when
making investment decisions, according to the Asset Owners Disclosure
Project. Funds listing climate as an investment criteria rose 18 percent
from last year.
“The Paris Agreement sent a clear message of global commitment to
tackle climate change,” said Julian Poulter, chief executive officer at
AOPD..."
Climate Denial in Schools. Keep an eye on attempts to question climate science in America's schools, according to a summary at VICE News: "...Currently,
six states have legislative measures pending or already on the books
that would allow anti-science rhetoric, including the rejection of
global warming, to seep its way into schools’ curricula. While these
types of proposals have become fairly routine in certain states, some of
the most recent crop have advanced farther than in the past. Senate
Bill 393 in Oklahoma, for example, would permit teachers to paint
established science on both evolution and climate change as
“controversial.” The “controversy,” however, doesn’t really exist — more than 97 percent
of actively publishing, accredited climate scientists agree that global
warming trends over the past century are directly attributable to human
activity. And some teachers might already be misleading students..." El Nino and the End of the Global Warming Hiatus. Here's an excerpt from Yale News: "...A
new climate model developed by Yale scientists puts the “global warming
hiatus” into a broader historical context and offers a new method for
predicting global mean temperature. Research by professor Alexey Fedorov
and graduate student Shineng Hu indicates that weak El Niño activity
from 1998 until 2013, rather than a pause in long-term global warming,
was the root cause for slower rates of increased surface temperature.
The research, published in the journal Geophysical Research Letters,
also finds that volcanic activity played only a minor role. “Our main
conclusion is that global warming never went away, as one might imply
from the term ‘global warming hiatus,’” said Fedorov, who has conducted
extensive research on the oceans’ role in climate. “The warming can be
masked by inter-annual and decadal natural climate variability, but then
it comes back with a vengeance...”

What a Year With a Single Tree Reveals About Climate Change. Here's a clip from The Boston Globe: "...Extremes
are the new normal as the changing climate works its way on the
landscape with varied effects. How trees are faring in the face of it is
not one story, even in one forest. At the Harvard Forest, red oak, the
dominant tree in these woods, is surging, at least for now, but warmer
winters also have set invasive woolly adelgids on the march, expanding
their range in a rampage expected to take out most of the eastern
hemlock at the Harvard Forest and beyond, as the bugs literally suck the
life out of them. The future, climate scientists warn, may bring
storms, droughts, fires, pest outbreaks, floods, and species
extinctions, scaling ever upward in severity according to our failure to
reduce carbon emissions and stop making our problem worse. Perhaps
there will be a technological fix. Perhaps we will figure out how to
break the connection among prosperity, comfort, and carbon. But this
much is for sure: In an uncertain world, forests can help..."

Extreme Arctic Melt is Raising Sea Level Rise Threat; New Estimate Nearly Twice IPCC's. Here's a clip from a story at InsideClimate News: "Global
sea level rise could happen at nearly twice the rate previously
projected by the U.N. Intergovernmental Panel on Climate Change, even
under the best scenario, according to a new report. By the end of this
century, as some glaciers disappear completely, the Arctic's
contribution to global sea level rise will reach at least 19 to 25
centimeters, according to the report by the Arctic Council's Arctic
Monitoring Assessment Program (AMAP). Factoring those numbers into
projections about other sources of sea level rise results in a minimum
of 52 centimeters of sea level rise by 2100 under a best-case scenario
and 74 centimeters under business as usual. "These estimates are almost
double the minimum estimates made by the IPCC in 2013," the authors
wrote..."
Climate Change Offers Huge Investment Opportunity: Experts.
What will get business on-board, focused on solutions? The profit
motive - every threat is a (financial) opportunity, as described by Reuters: "Climate
change should be grasped as an opportunity to attract vast capital
flows into low-carbon investments, create jobs and spur economic growth,
rather than viewed as a money-absorbing burden, top officials and
experts said. Yet while trillions
of dollars are potentially available for climate investments and
countries like India are blazing a trail in bringing cheap solar power
to millions, making sure the world’s poorest benefit will prove a major
challenge, a World Bank meeting heard late last week.
“It’s the biggest opportunity in the history of the world - it’s the
biggest investment opportunity, but we have to have a clear vision, we
have to have policy leadership... to bring the world community together
to get the financing that is needed to move the momentum more quickly,”
former U.S. Vice President Al Gore told the discussion..." Can We Fight Climate Change With Trees and Grass? Here's an excerpt from MIT Technology Review: "Can
we use trees and other plants as a weapon in the fight against climate
change? Earth's greenery comes with natural carbon-capturing abilities,
but now several studies are investigating how to tweak those tendencies
to have a maximum impact on carbon dioxide levels in the atmosphere. In
2014, the Intergovernmental Panel on Climate Change announced that plants would have to be a major part of the world’s efforts to capture CO2. The idea would be to have trees and grasses suck up CO2 as they grow, then burn or process them into fuels to generate power while capturing any CO2
produced along the way. This process is known as “bioenergy plus carbon
capture and storage,” or BECCS. We’re starting to see increasingly
large tests of the technology roll out..."
Early Warmth, Late Frost Wreaks Havoc on Wine-Growing Regions of France, Italy. Here's an excerpt from Wine Spectator: "...This
year the plants were 15 days in advance," said Blot. "It's impossible
to protect the entire vineyard. This year, as of today, I lost maybe 10
percent of the crop." Better than last year, but still a critical loss.
To the east and north, Burgundy and Champagne also reported heavy
damage, but growers were focusing on trying to combat the incoming cold
front before they sent detailed damage reports. To the southwest, the
Gironde Chamber of Agriculture reported frost damage in the greater
Bordeaux region, including the southern Médoc, sections of St.-Emilion
and Lalande de Pomerol, Bergerac, and the area around Blaye. Of course,
climate change means different things to different wine regions. And far
south in the Languedoc, frosts are so rare that this past week's
episode is the first major frost since 1998. "Climate change has brought
us warmer springs and fewer cold episodes," said Jerome Villaret,
director of the Languedoc wine council..."
