Winter in Temporary Retreat - Shot at 50F on Saturday?
30 F. high in St. Cloud Thursday. 30 F. average high on February 25. 13 F. high on February 25, 2015.
February 26, 1996:
A bolt of lightning from a snowstorm causes an explosion at a fireworks
storage site in Milaca. One employee was injured and several homes in
the area were damaged. An eight foot crater was all that remained where
the storage site had been. February 26, 1971:
Extremely low pressure moves across Minnesota. The Twin Cities had a
barometer reading of 28.77 inches and Duluth beat that with 28.75.
Freezing rain and snow hit northern Minnesota, dumping up to 18 inches
of snow in some areas. Areas around Virginia, MN were without power for 5
days. February 26, 1896:
A balmy high of 60 degrees is reported at Maple Plain. The warm weather
hampered the annual ice cutting on Lake Independence to store for
summer use.
Here's a New One: Spring Fever in February?
May
you live in interesting times. A year ago who could have predicted that
oil would drop to $27/barrel - or Donald Trump would be on top of the
GOP ticket? Predicting the future is hard work.
Just when you
think it can't get any weirder...it does. We've enjoyed a pretty tame
winter, all things considered. A couple of minor cold smacks, one
authentic "snowstorm". Remember those? And we've
gotten the better
end of El Nino. Kansas-size tornadoes have terrorized the Gulf Coast and
Florida; damaging twisters as far north as PennsylvaniaWednesday. Odd for February.
More evidence of a jumbo El Nino. This warm bias pushes the mercury to 40F today. Mid-50s are likely Saturday (the all-time record at MSP is 54F). Grilling weather in late February? Why not.
Don't take the fishing boat out of cold storage just yet. A light mix is expected Sunday; NOAA models hinting at snow next Tuesday, but the ECMWF (European) isn't buying it yet. I see a few days in the 20s the middle of next week.
An early spring? Probably. Earlier warmth and more severe T-storms than we've seen in recent years.
3 PM Temperatures on Saturday.
The map above wouldn't look out of place on April 3, but February 27? A
bit unusual, but not unprecedented. NAM guidance from NOAA shows
temperatures in the low to mid 50s in the metro; an outside shot at 60F
near Mankato. Source: AerisWeather.
Coldest Air Stays North.
Minor pulses of chilly air drain southward, but the core of the coldest
Canadian air pushes across central Canada and Hudson Bay into eastern
provinces; a mild Pacific signal continuing to dominate the weather over
the western two-thirds of America.
Vague Hints of Spring.
It's not spring, not yet, but European guidance confirms a glimpse of
lukewarm days to come on Saturday; another surge of 40s arriving Monday
before cooling into the 20s by the middle of next week. This may come as
a shock but no big storms are brewing, just a light mix Sunday. Source:
WeatherSpark.
Storm Track Shifts South and East.
More whispers of El Nino, which tends to energize the southern branch
of the jet stream, detouring the biggest, wettest (most severe) storms
south and east of Minnesota. GFS guidance shows significant snow late
next week from Indianapolis and Cleveland into much of New England.
Cooler Next Week, Then Warming Again.
GFS model guidance shows a rerun of 40s, possible 50-degree warmth
returning after March 9. Circle your calendar. I don't see a
headline-leading storm (of any flavor) into the middle of March.
Modified Zonal Flow.
GFS guidance shows unusually cold weather pushing into eastern Canada,
brushing the Great Lakes and New England two weeks from now, a
relatively mild Pacific flow for much of the USA.
Unusually Severe February Tornado Outbreak Strikes Gulf Coast States. Meteorologist Eric Holthaus has the story at Slate; here's an excerpt that caught my eye: "...At several points throughout the evening, multiple tornadoes were ongoing simultaneously and several areas were especially hard hit between New Orleans and Pensacola, Florida, where the National Weather Service had issued a “particularly dangerous situation” tornado watch. Buoyed by a strong jet stream linked to the record-strength El Niño, and slightly warmer than average Gulf of Mexico waters for this time of year, the storm packed an unnaturally springtime punch, producing a month’s worth of tornadoes in a few hours. On Tuesday morning, before the storms began, the National Weather Service estimated a near-record level tornado risk for the date, about 50 times higher than the historical average for late February..."

The Tornado Formula. Why is the USA the tornado capital of the planet? It's complicated. Here's an excerpt of a good explainer at The Atlantic: "...The
U.S. gets so many tornadoes because, in large part, the presence of the
Rocky Mountains and the Gulf of Mexico,” Harold Brooks, a scientist at
the National Severe Storms Laboratory, told me in an email. Those
features create the conditions for the three key ingredients necessary
for the kind of severe thunderstorm that can produce tornadoes:
1. Warm, moist air at low levels
2. Cool, dry air aloft
3.
Horizontal winds that increase with height from the ground-up—and
change direction, so that they blow from the equator at low levels, and
from the west aloft.
The United States sees all three of those ingredients..."

Follow The Trends.
Meteorologists call this "continuity", which is slang for "go with the
flow" as your best, first guiess moving forward in time. A turbocharged
El Nino signal continues to overwhelm other factors. Arctic temperatures
are running 7-15F warmer than average, and NOAA's CFSv2 (Climate
Forecast System) model predicts temperature anomalies of +8F across
Minnesota, even warmer over central and western Canada. Feeling a little
better about my guess-cast of an early spring. Map: WeatherBell.
As The Arctic Roads, Alaska Bakes In One of Its Warmest Winters Ever. The warming up north is nothing short of extraordinary; here's an excerpt from Jason Samenow at Capital Weather Gang: "This
winter’s shocking warmth in the Arctic, some seven degrees above
average, has oozed into the Alaska which is experiencing one of its
mildest recorded winters. So far this winter, Alaska’s temperature has averaged about 10 degrees above normal,
ranking third warmest in records that date back to 1925. Unusually warm
temperatures and a profound lack of snow are affecting areas all over
the state. The index which ranks the severity of winter shows Anchorage
is having one of its gentlest winters on record..."

Study: Within 80 Years, 80% of Wetlands Could Just Be Wet. Implications for Minnesota's wetlands? Here's a snippet from a recap of new research at Fusion: "Wetlands cover nearly 300,000 square miles of the globe, an area about the size of Texas and West Virginia combined. A new study
has shown that primarily due to sea level rise, this cover could be
reduced by as much as four-fifths by 2100, putting it more on par with
New York in size. By using new models to determine the impact of climate
change on wetlands across the planet, researchers from the U.K. and
Germany were able to determine that even with a low estimate of sea
level rise by 2100, about 11 inches, much of the world’s wetlands will
find themselves vulnerable to destruction..." (Image credit: AP). Not Just a Western Problem, Drought Threatens Forests Across U.S. Here's an excerpt from a story at CSMonitor.com: "...While
eastern forests have not experienced the types of changes seen in
western forests in recent decades, they too are vulnerable to drought
and could experience significant changes with increased severity,
frequency, or duration in drought,” scientists from 14 institutions,
including Duke University, US Department of Agriculture and US
Geological Survey, wrote in a paper published Monday
in the peer-reviewed journal Global Change Biology. The climate is
changing too quickly for trees to adapt to the dry conditions,
scientists say..."

is more important than geography when predicting how well seeds will
grow and establish themselves. Seeds don't care where their parents
lived if the temperature suits them and if they get the right amount of
sunshine and precipitation.
Timing
of seed planting makes a big difference. Year to year, even week to
week, variation in weather patterns can affect the restoration success
of a burned site.
The
method of planting matters. Blowing seeds from a plane may be a fast
way to cover a lot of territory, but it's not that effective. The seeds,
dropped from large drums attached to the planes, scatter in the wind,
sparsely covering the ground below. Their contact with the earth is also
less secure than for seeds planted in furrows by a tractor. As a
result, many of the seeds fail to establish themselves, and those few
individuals that do will not compete as well in nature as will the
densely planted seeds..."
Photo credit: PBS. National Geographic ScienceBlogs: Water, Security and Conflict. Violence Over Water in 2015. Is there a connection to what's happening in Syria and Libya? Here's an excerpt from Pacific Institute that raised a few eyebrows: "...Over
the past century there has been an increase in the number of reported
conflicts over water resources. Part of this increase is certainly due
to better reporting in recent years, but growing populations, rising
demands for water in water-scarce regions, and weak governance
structures and institutions for reducing conflicts at the local and
regional level may also be contributing to an increase. In the coming
years, far more effort is need to both understand the nature of these
risks and to develop diplomatic, economic, and institutional tools for
reducing conflicts over water resources. The Pacific Institute will
continue to be the leading source for collecting and analyzing
information on these challenges..."

Quit Apologizing! World Needs Fossil Fuels, Saudis Tell Oilmen. Here's an excerpt from Bloomberg Business: "In
addition to telling oil producers to cut costs or get out of the
market, Saudi Arabia’s energy minister delivered another unpalatable
message this week: the green movement can’t be ignored. Ali al-Naimi,
whose nation is the biggest exporter of crude, said that the industry
for too long “has been portrayed as the dark side” of energy by
environmentalists seeking to curb global warming. He urged executives,
who often try to sidestep the debate on climate change, to promote
technologies that will rein in emissions -- alongside the idea that
fossil fuels are needed to sustain economic growth..." EPA's McCarthy: "The Clean Energy Train Has Left The Station". Fuel Fix has the story - here's the intro: "U.S.
Environmental Protection Agency Administrator Gina McCarthy warned the
world’s energy leaders Wednesday they would need to adapt, shifting away
from fossil fuels towards cleaner burning sources like wind and solar
power. “The clean energy train has left the station, folks,” McCarthy
said at the IHS Energy CERAWeek conference in Houston. “We are really
hitting the ground running in 2016. The energy market is shifting and we
anticipate taking meaningful climate action.” In December close to 200
countries, including the United States, agreed to begin taking steps to
reduce greenhouse gas emissions towards keeping the earth’s temperature
from rising more than 2 degrees Celsius..."

envision a goal of zero emissions and 100 percent clean energy in
Minnesota by 2050, a goal that echoes the call from the youth who
gathered in Paris to demand a strong climate agreement that safeguarded
their future. We know what’s at stake. We’ve seen climate change alter
the Arctic as well as our winters here in Minnesota. The recent news of
2015’s record-setting heat is a sobering reminder that climate change is
not slowing down. We need to chart a path to a clean-energy future that
is faster than the path to climate catastrophe. We don’t have time for
pauses or delay. The good news is, the clean-energy industry is not
pausing either. In Minnesota, solar jobs have increased 131 percent
since 2013, according to the newly released Solar Jobs Census, and the
industry expects another 20 percent increase this year..."

Electric Cars "Will Be Cheaper Than Conventional Vehicles by 2022."
Far fewer moving parts, things that can go wrong or need maintenance,
as battery prices go down and range goes up there may be a perfect storm
within 5-10 years? Here's a clip from The Guardian: "Electric
cars will be cheaper to own than conventional cars by 2022, according
to a new report. The plummeting cost of batteries is key in leading to
the tipping point, which would kickstart a mass market for electric
vehicles, Bloomberg New Energy Finance
(BNEF) analysts predict. The large-scale roll-out of electric vehicles
(EVs) is seen as vital in both cutting the carbon emissions that drive
climate change and in dealing with urban air pollution, which leads to
many premature deaths every year..."
America's Massive New Transportation Infrastructure System is Hiding in Plain Sight.Atlas Obscura details the national network of superchargers installed by Tesla: "...Three
year ago, Tesla had only a handful of Superchargers in place; today
there are more than 270. Rival car companies are spooling out their own
networks of fast-charging stations, too. By the end of the year, Tesla
promises, its drivers will be able to use the Supercharger network to
drive through every state in the continental U.S. In March, Tesla has
promised to unveil its Model 3, which, at $35,000, will be the first
Tesla that’s not ridiculously expensive. But perhaps more importantly,
because of Tesla’s charger network, it’ll be the first one that will
require no compromise from owners on how far their car might take them..."
Report Suggests Minnesota Aim Beyond Clean Power Plan Target. Here's an excerpt at Midwest Energy News: "Minnesota
is well positioned to meet the requirements the U.S. Environmental
Protection Agency’s Clean Power Plan and could go much further with
higher renewable energy and energy efficiency goals. That’s according to
a new report
on Minnesota released today from the Union of Concerned Scientists
(UCS), which has begun publishing analyses of the plan’s impact on each
state. “The model shows us Minnesota is a leader on clean energy and
efficiency and that puts it in a great spot for meeting Clean Power Plan
requirements – and potentially go further than what the plan requires
in terms of carbon initiatives,” said Sam Gomberg, lead Midwest analyst
for the UCS’s Climate and Energy Program..."
Is Google's New Two-Legged Robot the Soldier of the Future? Here's an excerpt from Newsweek: "Boston
Dynamics, Google’s robotics subsidiary, has unveiled the latest version

Climate Stories....
EPA Draft Says Oil and Gas Methane Emissions are 27% Higher Than Earlier Estimates. Here's an excerpt from EDF, The Environmental Defense Fund: "Methane
emissions from the oil and gas industry are significantly higher than
previous official estimates, according to draft revisions of the U.S.
greenhouse gas emissions inventory released Monday
by the Environmental Protection Agency. At 9.3 million metric tons,
revised estimates of 2013 emissions are 27% percent higher than the
previous tally. Over a 20-year timeframe, those emissions have the same
climate impact as over 200 coal-fired power plants. The lost gas is
worth $1.4 billion at 2015 prices..."
James Hansen on Ice Sheets - 2016. Check out the latest video at Climate Denial Crock of the Week. Hansen has been called an alarmist, but his predictions have been remarkably precient, and accurate: "...I
finally caught up with James Hansen at the American Geophysical Union
Fall Meeting in December, and he gave a terrific interview, touching on
many key topics. Here, he gives a brief synopsis of one of the most
important points in his most recent paper. Hansen’s concerns, if borne
out, would mean substantially higher sea level rises than most other
researchers predict – but one hesitates to bet against someone with his
track record..."
Lord Stern Warns Economic Models are Underestimating Climate Risks and Clean Tech Opportunities. Business Green has the story; here's the intro: "The
economic models currently used to calculate the risks and costs
associated with climate change adaptation and mitigation are "grossly
misleading", Lord Stern has said. Writing in an article published today
in the journal Nature, the Grantham Institute chair and former Treasury
advisor urged researchers to help policymakers by better modelling both
the risks climate change presents to future generations and the vast
potential of clean technologies..."
Consumerism Plays a Huge Role in Climate Change.
No sacrifices necessary; just smarter, cleaner choices, rewarding
companies that offer low-carbon options. Here's an excerpt from Grist: "...A new study
published in the Journal of Industrial Ecology shows that the stuff we
consume — from food to knick-knacks — is responsible for up to 60
percent of global greenhouse gas emissions and between 50 and 80 percent
of total land, material, and water use. So, you know, get that Amazon
trigger finger ready, because you’re gonna want to do some comfort
shopping after this. “We all like to put the blame on someone else, the
government, or businesses. … But between 60-80 percent of the impacts on
the planet come from household consumption..." (Image credit: Realsociology).
Top Scientists Insist Global Warming Really Did Slow Down in the 2000s. Here's an excerpt of a Chris Mooney story at The Washington Post: "...The
authors also argue that a large body of research into the causes of the
apparent slowdown — which tended to target natural fluctuations, and
especially the behavior of the Pacific Ocean — represents valuable work
that advances our understanding of “a basic science question that has
been studied for at least twenty years: what are the signatures of (and
the interactions between) internal decadal variability and the responses
to external forcings, such as increasing GHGs or aerosols from volcanic
eruptions?” To be sure, the researchers behind the current paper
absolutely do not think that global warming is over or anything of the
sort — rather, the argument is that there was a real slowdown that’s
scientifically interesting, even if it was brief and is now probably
over..." (Image credit: Steve Burns).
What Is The "Pause" in Global Warming? Greg Laden takes a look at scienceblogs.com: "...When
climate science contrarians refer to a “pause” or “hiatus” in global
warming, they usually mean that the process of warming of the Earth’s
surface caused by the human release of greenhouse gas is not a thing.
They are usually implying, or overtly claiming, that the link between
CO2 and other greenhouse gas pollutants and surface warming was never
there to begin with, and previous warming, warming before “the pause,”
was natural variation. Many even go so far as to claim that the Earth’s
surface temperature will go down to levels seen decades ago. “The Pause”
is not, in their minds, a slowdown in the rate of warming. It is a
disconnect, either there all along or produced somehow recently, between
the physics of the greenhouse effect and reality..." Earth's Warming is 50x Faster Than When It Comes Out Of An Ice Age. We've
already committed to a sea level rise of 5.5 feet, based on the
(additional) greenhouse gases we've already pumped into the atmosphere?
The rate of warming is one (of many) factors that concern scientists;
here's an excerpt from The Guardian: "Recently, The Guardian reported on a significant new study published in Nature Climate Change, finding that even if we meet our carbon reduction targets and stay below the 2°C global warming threshold, sea level rise will eventually inundate many major coastal cities around the world.
20% of the world’s population will eventually have to migrate away from
coasts swamped by rising oceans. Cities including New York, London, Rio
de Janeiro, Cairo, Calcutta, Jakarta and Shanghai would all be
submerged.
The authors looked at past climate change events and model simulations of the future..."

The Link Between Zika and Climate Change. Analysis and perspective via The Atlantic; here's a clip: "...And
like other viruses spread by mosquitos and ticks, Zika could soon enjoy
a greater reach, thanks to climate change. Last year, a team of

Fiji's Climate Story is Bigger Than Winston.
The recent Category 5 cyclone (same as a hurricane) is one of many
symptoms of a rapidly changing climate; here's an excerpt from Pacific Standard: "...Winston's
trail of destruction is another painful reminder that many of the
world's smallest countries are among those most vulnerable to the
impacts of climate change. Rising sea levels caused by global warming
have already begun displacing coastal villagers in Fiji, and scientists
predict that low-lying island nations like Kiribati could be entirely underwater
by century's end. Meanwhile, the oft-repeated prediction that climate
change will lead to increasingly severe tropical storms appears to be
coming true. With sustained winds of 185 miles per hour, and gusts
surpassing 200 miles per hour, Cyclone Winston became the strongest storm ever recorded in the Southern Hemisphere..."
