October On Pause (9 day increase in Minnesota's growing season since 1st half of 20th century)
- Blog Post by: Paul Douglas
- October 9, 2013 - 1:06 AM
According to NOAA, Minnesota's frost-free season is 9 days longer now than it was from 1901 to 1960. It's 21 days longer in LA, Phoenix and Salt Lake City.
A warmer, wetter atmosphere is spiking winter snows as well as summer T-storms. Tell that to residents of Rapid City, where they just went from a 3-4 foot blizzard to 70s in 48 hours.<p>On Tuesday I spoke to the St. Paul Public Works, the men & women who service 863 miles of streets, 806 miles of sanitary sewers & 60 city-owned bridges.
I showed them the trends: more intense summer rains, higher summer dewpoints, more midwinter ice & rain and a potentially longer freeze-thaw cycle that may spawn ever-larger potholes. One manager approached me after my talk. "We're seeing evidence of more extremes. It'll be quiet for weeks and then all heck breaks loose. It makes staffing up almost impossible" he said.
Infrastructure designed in the 20th century will get a work-out in the 21st. Resilience is more than a passing fad.
70s linger into Friday, when a passing shower marks the arrival of October reality. Nothing bitter is in sight, but a light frost in the outer suburbs Monday gives way to steadier rain by Tuesday of next week.
Dear Mr. Douglas,
Again I want to thank you for your presentation today. I personally feel your data spoke for itself. Being an agency that responds to the events mother nature throws our way I can personally say that we have experienced the greater extremes of the weather events you have discussed. We will have intense snow storms followed by weeks of nothing. In 2010-11 season we declared nine snow emergencies contrast that with 2011-12 where we declared 1. We are also noticing 1” rainfalls, and occasionally 2”, as becoming more common than in the past.
As this phenomena continues it will make it harder for our agency to staff accordingly and meet our resident’s needs. In winter for example, if we staff to handle the big storms in a reasonable amount of time It means we will be over staffed for the “drought times”. Likewise if we staff for the “less snow times” It will take us longer to dig out of the heavy snows – which most likely brings complaints and its host of issues as our customers are not as patient as they used to be when I was growing up. They seem to have forgotten it snows in Minnesota.
Again thank you for the great presentation. Its News I can use.

Mild Into Friday - Then Back To October. ECMWF guidance above shows a weekend cool-down; 50s returning early next week, maybe even some 40-degree highs by the middle of next week with heavier, steadier rain. There's a slight chance of frost Monday morning, a better chance of frost next Thursday morning. Yes, we're due. Graph: Weatherspark.
Shifting Gears. GFS guidance shows another major, full-latitude trough spinning up a significant storm over the Plains and Upper Midwest (probably no blizzards or EF-4 tornadoes with this one), but it will tug seasonably cool air southward by the weekend. Meanwhile a nearly stationary storm triggers (minor) coastal flooding from the Carolinas northward to New Jersey. Map above shows predicted 10 meter wind speeds (green = strongest winds) and surface pressure, courtesy of NOAA and Ham Weather.
Increasingly Frost-Free. This October is a shining example of longer-term trends with Minnesota's growing season. The graphic above, courtesy of Climate Central, shows a 9 day increase in the growing season between 1991 and 2011, relative to 1901-1960.
9 Extra Frost-Free Days. There's a fairly compelling data set showing that Minnesota is experiencing 9 more days of frost-free weather than during the beginning of the 20th century. Out west, especially the Southwest USA, the number jumps as high as 21 extra days without frost. Details, and a fall color update, a look at how milder weather, deeper into autumn may be impacting photosynthesis and the vibrancy of those peaking fall colors - all in today's edition of Climate Matters.
Length Of The Growing Season. The EPA has more details on America's longer growing season. Here's an excerpt:
* The average length of the growing season in the contiguous 48 states has increased by nearly two weeks since the beginning of the 20th century. A particularly large and steady increase occurred over the last 30 years.
* The length of the growing season has increased more rapidly in the West than in the East. In the West, the length of the growing season has increased at the average rate of about 22 days per century since 1895, compared with a rate of about eight days per century in the East.
Autumn Falling Back. No, you're not imagining it. The wicked winds of winter are delayed (most years). A silver lining for many, but certainly more evidence that it's not your grandfather's weather pattern any longer. Graph above courtesy of Climate Central.
Federal Shutdown Affects Weather Agencies. Here's an excerpt of an article at The Tribune, serving San Luis Obispo: "Effects of the federal government shutdown have extended to weather-related agencies. The National Weather Service will continue to operate through the ongoing shutdown. Last week about 4,000 weather service employees were excepted from the shutdown to support its mission of protecting life and property. They will continue to issue forecasts and warnings 24-7. The employees don’t know when their next paycheck will arrive, however. Many of the National Oceanic and Atmospheric Administration (NOAA) web sites may not be available. For example, if you visit the National Data Buoy Center webpage, you may get an unavailable message. The government sequester combined with the shutdown not only is affecting their websites, but more importantly, also having an impact on marine buoy preventative maintenance, repair and replacement..."
Climatologist Says Slow Hurricane Season Winding Down. Too much Saharan dust, too much wind shear, too much dry air. It's a long laundry-list of meteorological alibis. Here's an excerpt from Louisiana's The Advertiser: "Two-thirds of the 2013 hurricane season is gone and, so far, no storms have hit the Louisiana coast. Predictions for an active storm season appear to have been wrong, says the state climatologist. With conditions in the Gulf of Mexico becoming less hurricane-friendly, the likelihood of a major storm hitting the Gulf Coast is decreasing daily, said Barry Keim, an LSU professor and state climatologist. Gulf waters reached their maximum temperature Sept. 10, which also is the peak of the storm season, and have been cooling. But he said he learned long ago, “in the weather world, never say never...” (Image: NOAA).
Weather Service Sees "Pineapple Express" Winter For Area. In this article at The Seattle Times I discovered that NOAA's ocean buoys, which provide essential data for mariners (and weather models) won't see routine maintenance until 2014, when budgets are (hopefully) restored, just one more impact of the government shutdown. Here's an excerpt: "...In the Northwest, El Niño winters are often warmer and drier; La Niña winters are typically colder and wetter. “Neutral” winters in the Puget Sound area are hard to predict, Buehner said, because the jet stream, directing moisture to the U.S. West Coast, tends to move over a wide area. “It’s like holding a hose about four feet back from the end. It tends to wiggle,” he said. Those winters, Buehner said, are often associated with storms that arrive in Western Washington carrying an “atmospheric river,” a narrow band of intensely wet air sometimes called a “Pineapple Express.” The three-month outlook from the Weather Service’s Climate Prediction Center calls for above-average temperatures and average precipitation in the Puget Sound area..."
Study Of April 27, 2011 Tornadoes Affirms Theories About Causes. A story at Claims Journal caught my eye - here's a clip: "...A new study of that outbreak gives forecasters and scientists who study severe weather detailed meteorological data about what happened that day, at the same time apparently affirming some new theories about factors that might enhance tornado development. “The indications are that gravity waves, topography and surface roughness each played at least some role that day in creating tornadoes or making them more powerful,” said Dr. Kevin Knupp, director of the Severe Weather Institute – Radar and Lightning Laboratories (SWIRLL) at The University of Alabama in Huntsville (UAH)..."
Flood Forensics: Why Colorado's Floods Were So Destructive. Here's an excerpt from an interesting story at NPR: "...If the soil becomes too wet, mountainsides collapse — and flow downhill. That's what happened across Colorado's northern Rockies. The floods started with a wall of moist air from the Gulf of Mexico that got trapped up against the Mountains, dumping almost a year's worth of rain in four days. As the overflow coursed through mountain ravines and canyons, it was like running a fire hydrant through a garden hose. But it wasn't just water. Streams became rivers of trees, boulders — and an avalanche of concrete. Farther along the highway, we find thousands of uprooted trees, dumped in a jumble by a flooded stream. Above the jumble, the stream bed has been scoured out..."

Heat-Expanded Water Blamed For Aggravating 2011 Japanese Tsunami. I'm continually amazed by how much we don't know what we don't know. Here's an excerpt of an interesting post at RTT News: "A research team says that heat-swollen water in ocean bedrock off northern Japan may have intensified the fault displacements that led to the devastating 2011 earthquake, increasing the size of the tsunamis. Earth scientists from ten nations including Japan, the United States and European countries say water in deep sea bedrock expanded due to frictional heat caused by the 2011 earthquake. This made the tectonic plates in the area more slippery, helping to trigger their large-scale movement. This phenomenon may have increased the size of the tsunami that followed the tremor, Japan's NHK broadcaster reported on Tuesday quoting the scientists.."

Rapid City FOX Stations Marooned After Weekend Blizzard. Thank God for Facebook (and snowmobiles). TVSpy has the remarkable story - here's the intro: "Staffers at Rapid City, SD, FOX affiliate KEVN found themselves stuck at the station after a snowstorm hit the area over the weekend. The station posted a plea for help to its facebook page yesterday, “Hey viewers we have a favor to ask! Is there anyone out there in Rapid City with a snowmobile that could help us out? We have been stranded at the station for days and desperately need to replenish the crew....”
We've Seen Frontline's Highly Anticipated Concussion Documentary, And It Is Very Bad For The NFL. Here's an excerpt from Buzzfeed: "As you watch League of Denial, the two-hour Frontline investigation premiering tomorrow night on PBS — as you watch its subjects, the men running the NFL, evolve from private ignorance to public dishonesty on the issue of concussions — you may at some point realize that a story about brain trauma has left you involuntarily shaking your own head. Eighteen months in the making, League of Denial is a triumph of investigative journalism into one of the most pressing public health crises of our time. It was only six weeks ago that ESPN, which had been a high-profile collaborator on League of Denial for the better part of a year, severed all ties with Frontline, citing a lack of editorial control..."
* ESPN has more on what the NFL knew about the concussion risk, and when they knew it here.
A Must-Watch Documentary. PBS Frontline is one of the last bastions of consistently great TV journalism these days, and they've upped the ante considerably with their latest subject, concussions and football safety, not only in the NFL, but among kids. The program goes nearly 2 hours, but the stories are powerful and compelling. Disclaimer: I'm a football fan. I don't want any of this to be true. But the data is the data and we probably need to keep our eyes wide open about the long-term risks. Sound familiar?
What's The Time In Antarctica? The answer may be harder to compute that you might imagine. Here's a clip from a story at The Economist: "Times zones sometimes have as much to do with politics as geography. Nepal pointedly runs 15 minutes ahead of its neighbour India. Cross the border from Nepal into Tibet and you have to put your watch forward by two-and-a-quarter hours, because China, which really spans five time zones, operates a single time across the land. At the other extreme, Russia has nine contiguous time zones, more than any other country. Until a few years ago it had 11. The problem of the poles applies just as much to the north as to the south, of course. But no one actually lives at the North Pole, which lies in the shifting ice of the Arctic Ocean. Antarctica, by contrast, is home to a small population of scientists, who need to keep track of time—especially during the non-stop daylight of summer and through winter’s endless night..."
Peak Soil: Why Nutrition Is Disappearing From Our Food. So you're telling me I could live to be 100 if the soil provided more nutrition? What do I do with THAT information? Details from The Week; here's a clip: "The fountain of youth may be made of dirt. So supposes Steve Solomon in The Intelligent Gardner: Growing Nutrient-Dense Food. He asserts that most people could "live past age 100, die with all their original teeth, up to their final weeks, and this could all happen if only we fertilize all our food crops differently." It's a bold statement, but mounting evidence suggests that remineralization could be the definitive solution to our nutrient-light diet. Concerns about the quality of our food tend to focus on the many evils of modern industrial farming, but 10,000 years of agriculture have created a more insidious problem. The minerals and phytonutrients historically derived from rich soil are diminishing in our produce and meat..." (Photo: AP).
Television News Graphics For The Visually Impaired. Good idea or gimmick? Here's an excerpt from TechCrunch: "And in this week’s episode of absolutely bizarre behavior from Fox News, we bring you BATS, officially known as big area touchscreens. The media outlet responsible for bringing fair and balanced news into our lives has today released a video that shows off the network’s brand-new Fox News Deck studio, a room filled with video walls and giant 55-inch touchscreens that will henceforth deliver the news to Fox News viewers, along with Shepard Smith. Why, you ask? To deal with “the new reality” as Senior Executive Producer Kim Rosenberg puts it, which includes “smartphones, apps, the internet, your computer.” As viewers change, so too must Fox News, and the only way to deal with the constant presence of the Internet is to build it right into the studio..."
Meet The Beer Fridge That Opens Only For Canadians. Time to get a Canadian passport. Then again... This is one of my favorite stories of the week; Mental Floss has the breaking news; here's a clip: "Next time you backpack Europe, it may be a good idea to take along your closest Canadian friend. You just might end up with all the free beer you’d ever want. To bolster national pride, Canadian beer company Molson placed beer fridges across Europe, from the streets of London and Brussels to the pastures of Belgium. Inside those fire engine red fridges? A free stockpile of Canadian suds. (Instead of planning a pub crawl through Europe, might we suggest a fridge crawl?) A public fridge chock full of free beer may sound like heaven to some, but there’s a problem: It’s locked. And there’s only one way to open it—you have be Canadian..."

Warming Lake Superior Prompts A Tribe To Try A New Fish. Arctic ice, glaciers and even large lakes are a good barometer of long-term temperature trends. Here's an eyebrow-raising article at The Daily Climate: "...The lake is warming faster than the atmosphere, said Jim Kitchell, a professor at the University of Wisconsin, Madison, and senior author of a new study examining the lake's fish. "Lake Michigan and Huron are warming but at half the rate [of Superior]." Over the past 40 years, the large, deep freshwater lake has had an average water temperature increase of about 5 degrees Fahrenheit, partly due to a 50 percent ice cover reduction over the same time. Such changes have increased suitable living areas for walleye by 223 square miles, one-and-a-half times the footprint of the city of Detroit. Chinook salmon and lean lake trout have seen habitat increase by 191 and 161 square miles, respectively, according to the study from Kitchell and colleagues..."
Preparing Minnesota for Climate Change: A Conference on Climate Adaptation. This daylong event is being held Thursday, November 7, 2013 9 am - 5:30 pm, followed by a reception at The Science Museum of Minnesota in St. Paul. This is the first annual gathering of local and state experts covering a diverse range of topics related to climate mitigation and adaptation in Minnesota, and some tickets are still available. I'll be there; if you're personally interested in this topic, or have an interest in possible impacts on your business or public sector duties in the years ahead you should plan on attending. Here's a good overview from the organizer of the event, Dr. Mark Seeley: "The first ever statewide conference on climate change adaptation practices will take place at the Science Museum in downtown St Paul on November 7, 2013 from 9:00 am to 5:30 pm. The cost for the conference is modest at $60 and includes lunch, breaks, parking, and a free pass to the Science Museum. This conference which is titled “Preparing Minnesota for Climate Change: A Conference on Climate Adaptation” has been designed by those who have been measuring and documenting the changing climate attributes in the state and their associated consequences. Professionals who have worked in transportation, agriculture, energy, health care, city planning, watershed and forest management, and the insurance industry will share their stories and experiences relative to adapting to our changing climate. The educational sessions will be followed by an evening reception in the Science Museum cafeteria at 5:30 pm so that informal socializing and networking among citizens and groups can occur." If interested in attending you can visit the web site for the conference at www.wrc.umn.edu
Can The Insurance Industry Weather Climate Change? The data is the data, and there are few climate change agnostics in the trenches of the world's major insurance companies. They can SEE what's happening with storm-related claims. Any doubts will soon be erased as our insurance premiums rise to keep some of these big companies afloat. Here's a clip from a story at LinkedIn: "...These things hit insurers hard. Zurich Insurance Group, the biggest Swiss insurer, downgraded its revenue targets after "natural catastrophe losses cut second-quarter profit by 27 percent," reported Insurance Journal in August. And it's not just hurricanes. Strong thunderstorms and rain across the greater Toronto metropolitan region in July caused significant flooding and power outages to the tune of US$1.41 billion, about half of which was covered by insurance, according to The Royal Gazette. "Nowhere in the world is the rising number of annual natural catastrophes more evident than in North America," according to Severe Weather in North America, a 2012 report (download) published by reinsurance giant Munich Re, which insures other insurers, thereby limiting the loss any single insurer would experience in case of disaster. "This increase is entirely attributable to weather events, as there has been a negative trend for geophysical events..."
New Finding Shows That Climate Change Can Happen In A Geological Instant. Rutgers University has a new study out that made me do a triple-take; here's an excerpt: "Rapid” and “instantaneous” are words geologists don’t use very often. But Rutgers geologists use these exact terms to describe a climate shift that occurred 55 million years ago.In a new paper in the Proceedings of the National Academy of Sciences, Morgan Schaller and James Wright contend that following a doubling in carbon dioxide levels, the surface of the ocean turned acidic over a period of weeks or months and global temperatures rose by 5 degrees centigrade – all in the space of about 13 years. Scientists previously thought this process happened over 10,000 years..."

How Carbon Became Political Kryptonite In Virginia's Gubernatorial Election. ThinkProgress has an update; here's the introduction: "Terry McAuliffe and Ken Cuccinelli have been battling for control of Virginia’s Executive Mansion all year. It’s not often that energy and climate change play a significant role in gubernatorial races but if it’s true anywhere, it’s certainly true here. A new report on the consequences of Cuccinelli’s climate denial, brand-new polling on the race, and an interview with Climate Progress make clear that refusing to do anything about carbon pollution could be political kryptonite, while embracing alternative energy and mainstream climate science could lead to electoral success..."

Toppling Climate Change Investment Myths. Here's a clip from a story focused on climate trends and investment objectives, courtesy of greentechmedia: "...So what does this mean for the financial community? Institutional investors who are inclined to be cynical about climate change are probably picking the wrong answers to five key questions.
First, isn’t the science too uncertain to act? No. Over the past five years, the scientific consensus has concluded resolutely that human emissions of greenhouse gases are heating the planet and will continue to do so. There is uncertainty over the rate of warming and the effect of feedback mechanisms, especially clouds, so future climate and weather conditions can only be thought of in terms of potential scenarios. Yet investors are trained to make decisions around a range of outcomes..." (Photo credit above: AP).
Tackling Climate Change: Copenhagen's Sustainable City Design. You'll be hearing more about sustainability and resilience in the years to come. Copehagen is doing many things right, as described in this excerpt from The Guardian: "...And those convex streets? They are main thoroughfares designed by Copenhagen's city planners to capture water from storms and flooding and direct it to the harbour. Copenhagen in 2050 will also feature smaller streets with plenty of trees, which will slow anticipated flooding "so not everything comes bursting into the cloudburst boulevards at the same time", Leonardsen explains. Pocket parks will absorb heat and can be turned into water storage during weather emergencies. In addition to storms, flooding and rising sea levels, heatwaves are the most dramatic scenario facing cities as climate change worsens..."

Climate Fact: Arctic Sea Ice Is Shrinking, Antarctic Sea Ice Is Growing. Why? EarthGauge has the story - here's a snippet: "The Arctic and Antarctic sea ice expands and contracts with the seasons: melting occurs during summer and expansion occurs during winter. The Arctic reaches its minimum extent in September at the end of summer in the Northern Hemisphere. On the other hand, the Antarctic sea ice reaches its greatest extent in September at the end of winter in the Southern Hemisphere. The Arctic and Antarctic are very different geographically. The Arctic is surrounded almost entirely by land (North America, Greenland and Eurasia), which traps most of the sea ice in the Arctic Ocean and allows multiyear ice to develop. Antarctic sea ice is bounded to the south by the Antarctic continent and completely exposed to the Southern Ocean to the north, which allows sea ice to expand in the winter but does not offer much protection during the melt season. This means that there is little multiyear sea ice in the Antarctic and most of the sea ice melts during the summer season..."
