70 F. record high in the Twin Cities Saturday, breaking the old record of 69F on March 12, 1990.
39 F. average high on March 12.
62 F. high on March 12, 2015.

Premature April Showers – Then Cooling Off
There’s a first time for everything. On Saturday, at our cabin north of Brainerd, I was wandering the beach in shorts and a T-shirt, fiddling with the A/C in my truck, wondering out loud what month it was. March or May?
Weather never repeats but sometimes it rhymes. 2016 is looking more and more like 2012, when flowers were blooming in late March and Minnesotans enjoyed a 7-month boating season. The reptilian side of my brain is enjoying this immensely – my analytic side has nagging doubts.
The premature ripple of warmth that triggered a new record high in the Twin Cities Saturday pulls enough moisture north for spotty rain showers today; steadier rain Tuesday may end as a mix late Wednesday. The ECMWF model hints at wet snow or a sloppy mix next weekend, a raw reminder that it’s still March. Slush is possible.
Temperatures cool off into the upper 30s next weekend (average!) but GFS guidance hints at 50s and heavy rain returning by the end of next week.
Shrinking winters, super-sized summers, May showers in March? I’m sorry, where are we living again?
Sunday Records. 70 F. in the Twin Cities broke the old record set in 1990. It’s the normal high for May 18.
A Long, Slow Slide. Not exactly arctic, but a “temperature readjustment” is brewing later this week as the mercury droops into the 40s – GFS guidance predicts highs in the upper 30s next weekend. Graphic: Aeris Enterprise.
March Stages a Sloppy Comeback. The transition back to “average” will whip up a few waves of precipitation: showers today and Monday; steadier, heavier rain Tuesday. Another southern storm may push a shield of moisture into Minnesota and Wisconsin next Saturday; the atmosphere marginally cold enough for wet snow or a mix. Way too early for details – not sure it’s even real yet.
Heavy Rain Potential Tuesday. Our internal model ensemble sent out an alert yesterday for a potential of 1″ or more of rain by 4 PM Tuesday in the Twin Cities.
In Honor of St. Patty’s Day: Plenty of Green. A spurt of southern moisture pushes showers into Minnesota this morning; spotty showers spilling into Monday with a few hours steadier, heavier rain Tuesday as colder air arrives on gusty northwest winds. 12 KM NAM future radar: NOAA and AerisWeather.
Greening Lawns Within 2 Weeks? I can’t promise flowers will be blooming in March (like 2012) but NAM guidance prints out some half inch rainfall amounts around the metro area, a few isolated 1″ rainfall totals by Tuesday morning over central Minnesota.
Premature April Showers. NDFD, GFS and GFS ensemble model data all print out over 1″ of precipitation by Friday morning (the vast majority falling as rain).
Minor Weekend Slushing? 10-Day GFS accumulated snowfall predictions pull in a slushy coating by Friday and Saturday; heavier amounts over far northern Minnesota by Sunday and Monday. One more chance to fire up the snowmobiles? Don’t hold your breath.
Is March Still The 3rd Snowiest Month of the Year? Mark Seeley answers a question at Minnesota WeatherTalk that caught my eye; here’s an excerpt: “…Using a 115 year climate record from Detroit Lakes (Becker County), just up the road from Perham is revealing with respect to seasonal snowfall distribution. In the first 75 years of climate records at Detroit Lakes March was the snowiest month of the snow season over a third of all years. But since the winter of 1965-1966 it has been the snowiest month of the season only three years (1985, 1996, and 2002). Further much more of March precipitation has fallen as rain rather than snow in recent decades. Since the new millennium, March has on average been the 3rd snowiest month of the snow season trailing December and January, at least in the Detroit Lakes area…”
The Fuel Behind Louisiana’s Torrential Rains, Floods. Here’s a clip from Climate Central: “…In general, climate scientists expect heavy downpours to increase over the U.S. and elsewhere, as a warmer atmosphere can hold more moisture, making more of it available to fall as rain. Observations have already shown an increase, though the amount varies from region to region. The Southeast as a whole has seen a 27 percent increase in the amount of rain falling in the heaviest events since 1958. Baton Rouge ranks among the top 20 cities in terms of the increase in heavy downpours it has seen, with a 120 percent increase since the 1950s, according to a Climate Central analysis…”

1-in-200 Year Flood for Louisiana? So says Dr. Jeff Masters at Weather Underground, analyzing the unusual (stalled) storm that sparked thunder-snow for Mexico and a 7-day firehose of Gulf moisture for the Lower Mississippi Valley: “A remarkably rare atmospheric event is unfolding over Mexico and the Southern U.S., where an upper-level low pressure system of unprecedented strength in the historical record for that location has stalled out, bringing multiple days of torrential rain to the Southern U.S. and snow to the mountains of Mexico. The upper low tapped into an atmospheric river of moisture from both the Western Caribbean and the Eastern Pacific, bringing rainfall amounts one would expect to occur only once every 200 years (a 0.5% chance of occurrence in a given year) over portions of northern Louisiana...”

In The Arctic It Was More Than 10 Degrees (C) Too Warm. I used Google Translate to share a story excerpt from Suddeutsche Zeitung in German: “…Experts from the European Centre for Medium-Range Weather Forecasts (ECMWF) could in an area extending from Finland to Greece and to the east through Western Siberia, Kazakhstan and the northern part of Western Asia, measure significant changes in temperature. In February, the temperature in this area by more than five degrees above the monthly average – compared with the month of February from 1981 to the of 2010. Even more than ten degrees above the monthly average temperatures were in the northern part of the Barents Sea and the North-West of Russia, so in parts of the Arctic…”

U.S. East Coast Sea Level and The Gulf Stream. Sea levels are rising, but fluctuations in the intensity of the Gulf Stream can magnify the effects; here’s an excerpt of a post from Dr. Larry Atkinson at WunderBlog: “…So how will the Gulf Stream change if climate is changing? Well, for a long time oceanographers predicted that under a warmer future climate the Atlantic Ocean circulation (represented by AMOC) will slow down. In high latitudes water will become warmer and fresher (from melting ice), so they will be less dense and will not sink as fast as before. Therefore, if the Gulf Stream will also weaken, sea level along the coast will rise. Recent research in fact found evidence in data that this Gulf Stream slowdown may have started already and the result can be seen in accelerated rate of sea level rise (Link) The figure below demonstrates that during periods of slowdown in the Gulf Stream, coastal sea level is often higher than normal, causing increase in flooding...”
The Global Solution to Extinction. Here’s an excerpt from The New York Times: “…But today the dream is at risk. Civilization is at last turning green, albeit only pale green. Our attention remains focused on the physical environment — on pollution, the shortage of fresh water, the shrinkage of arable land and, of course, the great, wrathful demon that threatens all our lives, human-forced climate change. But Earth’s living environment, including all its species and all the ecosystems they compose, has continued to receive relatively little attention. This is a huge strategic mistake. If we save the living environment of Earth, we will also save the physical, nonliving environment, because each depends on the other. But if we work to save only the physical environment, as we seem bent on doing, we will lose them both…”
report on the fast-expanding electric car market by Bloomberg New Energy Finance. The report says that even if petrol or diesel driven cars improve their fuel efficiency over the coming years, the cost of owning an electric car – buying it and running it – will be below that of conventional vehicles by 2022…”Within six years, the cost of owning an electric car will be cheaper than purchasing and running a petrol or diesel model. That’s the conclusion of a

22 Amazing Renewable Energy Projects That Pave The Way to a Cleaner Future. Gizmodo has the photo essay; here’s an excerpt: “There’s a growing demand for greener, safer renewable energy sources. Sun, wind, water, biomass, waves and tides, and the heat of the soil, all provide alternatives to non-renewable energy. The following collection showcases some of the most amazing renewable energy projects and prototypes from the past few decades, including quite a few you’ve probably never heard of before…”

Republican businessman Jay Faison is searching for the middle ground. His organization, ClearPath, aims to convince conservative politicians that clean energy is a winning cause. This week, ClearPath opened offices in Washington and launched a $1 million digital ad campaign to promote conservative clean-energy principles. It’s part of a broader multi-million-dollar foundation and super PAC aimed at driving GOP support for “common-sense” solutions to energy and climate problems. Winning over his fellow party members may not be easy, but Mr. Faison says embracing clean energy is critical to the future of both his party and his country...”

Tackling Climate Change is a Profitable Opportunity, Rather Than an Expensive Problem. America has a long, storied history of turning negatives into positives. Here’s a clip at Huffington Post: “…Looking at how we consume energy and in particular the resulting waste will go a long way in helping us better understand the real issues at stake. The technologies we use today are 100 years old! They present a complete lack of efficiency compared to the clean technologies available: our combustion engines are three times less efficient than electrical ones; light bulbs create more heat than light and in turn require cooling devices; poor insulation of buildings and single glazed windows continue to run up our monthly electricity bills; and, heating and cooling systems, as well as industrial processes produce more losses than efficiency. Why are we so demanding about modern information technology and so relaxed about energy efficiency?…”
The Obama Doctrine. Even if you’re not a fan of President Obama’s policies you should read this article from Jeffrey Goldberg at The Atlantic; here’s an excerpt: “…Obama, unlike liberal interventionists, is an admirer of the foreign-policy realism of President George H. W. Bush and, in particular, of Bush’s national-security adviser, Brent Scowcroft (“I love that guy,” Obama once told me). Bush and Scowcroft removed Saddam Hussein’s army from Kuwait in 1991, and they deftly managed the disintegration of the Soviet Union; Scowcroft also, on Bush’s behalf, toasted the leaders of China shortly after the slaughter in Tiananmen Square. As Obama was writing his campaign manifesto, The Audacity of Hope, in 2006, Susan Rice, then an informal adviser, felt it necessary to remind him to include at least one line of praise for the foreign policy of President Bill Clinton, to partially balance the praise he showered on Bush and Scowcroft…”
The “AT&T Spokesperson” is a Political Refugee. Unless you have Apache, Cheyenne or Sioux blood chances are you’re the offspring of an immigrant. So is the gal who shows up in those ubiquitous AT&T ads on TV, a political refugee who came to the USA from Uzbekistan when she was 2 years old. Here’s an excerpt at looper.com: “…Life in the USSR wasn’t exactly sunshine and rainbows for Vayntrub’s family, especially because they faced persistent religious persecution for being Jewish in a country that was officially atheist. When Vayntrub was just two years old, her family fled Uzbekistan in hopes of finding religious freedom and political asylum in America. The process was long and grueling, with the family stranded in both Austria and Italy for a while. Luckily, the Vayntrubs made it to America and settled in California, which sounds like a wonderful step up to us…”
Computers Will Overtake Us When They Learn to Love, Says Futurist Ray Kurzweil. I’ll be happy if I can get my computer to work – without pleading, swearing and shrugging. CNN Money has an interesting story; here’s a clip: “Ray Kurzweil, the celebrated American inventor who keeps predicting the future with scary accuracy, says computers will match — and possibly beat — human intelligence by 2029. Here’s the trick: By then, computers will possess emotions and personality. “When I talk about computers reaching human levels of intelligence, I’m not talking about logical intelligence,” Kurzweil said at an event in New York on Monday night. “It is being funny, and expressing a loving sentiment… That is the cutting edge of human intelligence…” (File image: CNN).
The Real-World Locations of 14 Sci-Fi Dystopias. From Blade Runner to the Hunger Games to The Matrix, where did they film these scenes (it wasn’t all CG, or computer graphics). Atlas Obscura has a long, visual and fascinating story; here’s an excerpt: “…The Metacortex building, where Neo (Keanu Reeves) works as a programmer and first suspects something’s not right with the world, is actually the Metcentre, a shopping mall in Sydney’s Central Business District. The bridge where Neo waits for Trinity (Carrie Ann Moss) to collect him in a car and bring him to meet Morpheus (Laurence Fishburne) is the Adam Street Bridge near Sydney’s Chinatown...”

Batnado! Just when you thought you saw everything, along comes this post at Tech Insider: “When dusk falls, 20 million Mexican free-tailed bats swoop out of Bracken Cave near San Antonio, Texas. After spending the winter in Mexico, the bats fly north to procreate. By August, the pups can fly and the colony size reaches its peak. Each night, the Bracken bat colony can eat 200 tons of moths, according to the Texas Parks and Wildlife Department. Feel what it’s like to stand at the cave’s entrance in this awesome video from National Geographic…”

Miami Beach Mayor Rips Rubio: He “100 Percent” Sounds Like a Climate Change Denier. Here’s an excerpt at Raw Story: “…Philip Levine, mayor of neighboring Miami Beach, said Rubio was “100 percent using the language of a climate change denier” and has overlooked the escalating problem of sea level increases for south Florida. Miami Beach has already spent $100 million on new sea defenses to curb the regular flooding of its western half. Sea levels are expected to rise in south-east Florida by six to 10 inches by 2030, with ever increasing levels throughout the century unless greenhouse gases are severely cut. These increases risk inundating large areas of the region, with 2.4 million people living within 4ft of the local high tide line...”
Money Doesn’t Matter: White People Breathe Cleaner Air. Here’s an excerpt of a story at Grist that made me do a double-take: “…For the most part, even when controlling for poverty, race is a far better indicator when it comes to determining who lives under a cloud of pollution in the United States. Thanks to a new, interactive air pollution index created by the National Equity Atlas, you can have a closer look at what that means, state to state and city to city. Here’s how it works: The average person in the U.S. lives in a place that ranks in the 50th percentile for air pollution exposure, based on the EPA’s 2011 National Air Toxics Assessment. Anyone below the 50th percentile is essentially breathing better air than the average American, and anyone above the 50th is worse off…” (Graphic: National Equity Atlas).
Racism and the Effects of Climate Change. Those with the least are first to be impacted by a more volatile climate, making this the civil rights movement of the 21st century. Here’s an excerpt at The Philadelphia Tribune: “…Fifty percent of people of color live within two miles of areas of pollution,” said Beverly Wright, executive director of Dillard University’s Deep South Center for Environmental Justice. “There need to be buffers. We need a special distribution of polluting facilities. The people least responsible are the most affected.” Wright said those involved in environmental justice have a tough job fighting against corporations, utilities and government officials who are intent on decimating the environment. The professor said race is a predominant indicator that determines the exposure some communities receive to assorted toxins, chemicals and pollutants. “Climate change is a threat multiplier for the Black community,” said Leslie Fields, director of the Sierra Club’s Environmental and Community Partnership Programs. “Our children have asthma, miss school, fall behind and end up in the school-to-prison pipeline. African Americans are disproportionately affected by climate change and are demanding action…”

How Climate Change Challenged, Then Strengthened My Faith. Here’s an excerpt of an Op-Ed at Religion News Service: “…When I was younger, God’s presence in nature was affirmation of this. When it dawned on me that creation itself was actually being destroyed, my faith faltered. Now, I realize that God is revealed to us not only through creation, but even more so through the suffering we feel on account of our love for it. I feel the Holy Spirit within me when I advocate for climate justice, and 10 times more strongly when I see the millions of others doing the same. I see Christ in the faces of those putting themselves on the line to preserve this planet for our children, and I know that God has not abandoned us, but is very much with us.”
Truth in Advertising. Here’s an excerpt of an interesting article from EnergyDesk at Greenpeace: “…Across the Atlantic and in complete contrast, North Vancouver is implementing compulsory anti-smoking-style warning stickers for fuel pumps at petrol (or ‘gas’) stations. These ads will use text and images to remind customers of the climate impact of the fuel they’re buying, in the hopes that drivers will consider their fuel consumption more carefully and perhaps drive more fuel-efficiently. Or just drive less. Do it for the moose, Canada.”
Climate Change Impact on Agriculture May Be Underestimated. Here’s an excerpt at IFT.org: “…This study, which focused on an area in Brazil called Mato Grosso, found that if the patterns from 2002 to 2008 hold in the future, an increase in average temperature of just 1 degree Celsius will lead to a 9%–13% reduction in overall production of soy and corn. In addition, though, how farmers react to these changes will also impact production. For example, farmers might choose to put less land area into production because it is not profitable, or they might choose not to plant a second crop in a growing season—a common practice in Mato Grosso known as double cropping…” (File photo: Nati Harnik, AP).
What Weather Is The Fault of Climate Change? Are we really spiking storms and droughts? The problem of attribution is addressed by climate scientist Heidi Cullen at The New York Times; here’s an excerpt: “…But some of our weather has changed significantly, and now a new report from the National Academies of Sciences, Engineering and Medicine has outlined a rigorous, defensible, science-based system of extreme weather attribution to determine which events are tied to climate change. Like the surgeon general’s 1964 report connecting smoking to lung cancer, the report from the National Academies connects global warming to the increased risk and severity of certain classes of extreme weather, including some heat waves, floods and drought. This is an important development. Climate change can no longer be viewed as a distant threat that may disrupt the lives of our grandchildren, but one that may be singled out as a factor, possibly a critical factor, in the storm that flooded your house last week. The science of extreme weather attribution brings climate change to our doorsteps…”
* More perspective on the new NAS study from Chris Mooney at The Washington Post.
Links Between Climate Change and Extreme Weather Are Increasingly Clear and Present. Here’s more perspective on the NAS report from Capital Weather Gang: “…We obtain those answers by comparing the event that just happened to a reconstruction of what might have happened if humans hadn’t changed the climate. In one common method, scientists perform many realistic computer model simulations, over long times (in computer years), of both the present climate, and the climate of a hypothetical, cooler world without human influence. In each climate, they count how often events occur that are similar to the one that happened in the real world. If they happen twice as often (say) in the simulated present climate as in the hypothetical climate without humans, then we say that human-induced climate change made the event twice as likely as it would have been otherwise. Of course, the results could also show that the event is about equally likely in both climates, or less likely in the present climate (as is generally true for extreme cold snaps)…”

Record Annual Increase of CO2 Observed at Mauna Loa in 2015. Here’s an update from NOAA: “…The last time the Earth experienced such a sustained CO2 increase was between 17,000 and 11,000 years ago, when CO2 levels increased by 80 ppm. Today’s rate of increase is 200 times faster, said Tans. The big jump in CO2 is partially due to the current El Niño weather pattern, as forests, plantlife and other terrestrial systems responded to changes in weather, precipitation and drought. The largest previous increase occurred in 1998, also a strong El Niño year. Continued high emissions from fossil fuel consumption are driving the underlying growth rate over the past several years…”

This Mind-Boggling Study Shows Just How Massive Sea Level Rise Really Is. Pump ocean water to Antarctica to slow the rate of sea level rise? Huh? Here’s a clip from The Washington Post: “…The problem with using geoengineering to counter rising seas is that every millimeter of sea level rise is equivalent to 360 billion tons of ocean water. And seas are currently rising at a rate of over 3 millimeters per year, with the rate of increase expected to grow still further in the future. The modeling study suggests that pumping water deep into the center of Antarctica, 700 kilometers inland and over two miles into the air, would indeed keep it there for a good while. Here, the addition of one meter’s worth of sea level rise would translate into raising the total elevation of continental ice by 25 meters…”
