June 9, 2002: Extensive flash flood begins across northwest Minnesota. 14.55 inches would fall over the next 48 hours near Lake of the Woods. Floodwaters cover the city of Roseau. The Roseau River looked like a large lake from a satellite view.
Hot Flash: Weekend Heat Index in the Danger Zone
“It’s a sure sign of summer if the chair gets up when you do” wrote Walter Winchell.
I’m still amazed baking heat is even possible at this northerly latitude. Just a few months ago people were driving on the lake out back; frozen ground as rock-hard as a North Dakota drill bit.
It’s not necessarily a preview of an inflamed summer to come, but Friday WILL take your breath away. Literally. Models suggest low to mid 90s with a dew point in the mid-70s, creating a Heat Index close to 100F by late afternoon.
Swamp-like. Florida on a bad day.
The approach of super-heated air sets off a few morning thundershowers; a growling reminder that much of the rain falling in June is from nocturnal thunderstorms: the result of low-level winds interacting with warm frontal boundaries.
I expect enough sun for mid-80s later today, but 90s are likely Friday into Sunday. A feeble frontal passage drops temperatures (slightly) up north Saturday; weather still looks lake-worthy.
We’re still not acclimated to the heat. Take it extra-easy out there, starting Friday. A taste of Dog Days to come.
4 KM NAM Model: 4 PM Friday. Check out the predicted surface temperatures at 4 PM tomorrow; close to 100F over west central Minnesota, probably low 90s in the immediate metro area. With a dew point in the low to mid 70s that could make for some might-uncomfortable heat indices. Source: AerisWeather.
“Unprecedented” Severe Weather Outbreaks Across Central Europe. My German is a bit rusty, but my 86-year old father was born in Germany – he’s still fluent, and he translated the gist of a story at Germany’s Tagesschau: “The headline says 3000 severe weather warnings/alerts in two weeks. The text says this is unprecedented for central Europe. It never happened since records were started, which dates back to the late 1800s…”
Attacking Storm Chasers Doesn’t Accomplish Anything, And It’s Often Misinformed. Here’s an excerpt of a retort to a recent Eric Holthaus column from Ian Livington at Capital Weather Gang: “...Chasers, ranks filled with tons of meteorologists, are generally smart folks and excellent risk assessors. Observers should keep this in mind while continuing to judge us on safety practices and choices when it comes to proximity to tornadoes. The well-known chasers who were killed in 2013, led by tornado researcher Tim Samaras, were giants of the field. But they chased in a particularly dangerous way while trying to put probes in front of tornadoes. Most chasers don’t chase that way. And very few are out there with, as Holthaus calls it, “dollar signs in their eyes, as bystanders’ livelihoods are destroyed…”
The Storm and the Fury: 80 Vintage Photos of Hurricane Seasons Past. NOLA.com in New Orleans has a terrific photo essay; here’s an excerpt: “Bring up the subject of hurricanes to most residents of South Louisiana, and killer storms like Betsy in 1965, Camille in 1969 and She-Who-Shall-Not-Be-Named in 2005 crop up consistently. But time and again over the decades, the fortitude of locals has been tested by storms that — while maybe not as well remembered as those name-brand milestones — were still just as life-altering for many local residents. Time and again, locals have proven equal to the task; Louisianians are not prone to bowing down in difficult times…”

With iPhone and Computer Models, Do We Still Need Weather Forecasters? I’m a bit biased, of course, but I would hope that there’s always a place for context, perspective and analysis, adding value above and beyond what a computer can do, but who knows? Choosing which model to believe is another ongoing challenge. Here’s an excerpt from Ars Technica: “…But most everybody has looked on their phone or some other device already. So what am I going to do? Am I just going to rehash everything they already know?” Many forecasters have been asking themselves this question lately. Two technologies have converged to rapidly displace the primary function of meteorologists. First are computers that are generally better forecasters than humans. For most types of weather, numerical weather prediction has superseded human forecast methods. And secondly, thanks to the Internet and increasingly ubiquitous weather apps on mobile devices, people have continuous, immediate access to 5-day, 7-day or 10-day forecasts. As technology drives automation and machines take job after job once performed by humans, are meteorologists next in line?...”

Humans Misread Wind Speeds, Skewing a Major Hazards Database. We came along this curious story at EOS, Earth and Space Science News; here’s the intro: “People may think they know how hard the wind is blowing, but science shows that they usually get it wrong. Researchers have known this for years, but a recent study seeks to quantify just how bad humans are at figuring out the speed of wind gusts without the aid of meteorological instruments. The authors of the study seek to make other researchers more aware of human bias when using Storm Data, one of the largest publicly available storm databases. The study, published in a recent issue of Journal of Applied Meteorology and Climatology, uses a large-scale statistical analysis of information from the database to investigate how much storm reporters’ estimates of wind speeds differ from measurements…”

Massive Rehearsal Planned for Northwest Megaquake, Tsunami. WCBD News 2 has the story – here’s an excerpt: “Imagine a devastating earthquake and tsunami have cut off Pacific Northwest coastal communities. Phone and internet service have collapsed. Ham radio operators living on the stricken coast fire up their radios, contact emergency managers and report on the magnitude of the disaster so that no time is wasted in saving lives. This is the kind of scenario that will be rehearsed during the second week of June in a massive earthquake and tsunami readiness drill that has been developed by the U.S. government, the military, and state and local emergency managers over the past few years to test their readiness for what — when it strikes — will likely be the nation’s worst natural calamity…”

An Attack on the Grid? Power Execs Push Back on Koppel Claims. USA TODAY has the article; here’s an excerpt: “Eight months after veteran broadcast journalist Ted Koppel published a book predicting a devastating cyberattack on the U.S. power grid, leaders of the utility industry are sounding off over what they say is an exaggerated claim. “We’re speaking out on it now because we think there is an important story to tell,” Scott Aaronson, the managing director for cyber and infrastructure security at the Edison Electric Institute, said last week at a briefing for reporters...”
How One Man Has Explained Almost Every UFO Theory. Here’s an excerpt from an interesting read at Atlas Obscura: “…To do this, he has combed through decades of supposed UFO sightings, reading eyewitness testimony and cross-referencing it with mission logs. In the process, he’s come to an interesting conclusion: human senses, evolved in and trained on (relatively) slow-moving objects, certain light conditions, and an atmosphere, get thrown into a tizzy when those conditions change. “Our sensory system is functioning absolutely perfectly for Earth conditions,” says Oberg. “But we’re still a local civilization. Moving beyond our neighborhood has been visually confusing...”

The U.S. population is about 319 million people, and it’s projected to reach a whopping 400 million by 2051. As our population grows each year, so does our impact on the environment in a number of dramatic ways. Americans’ increasing need for energy is certainly an environmental hurdle we will need to jump over. Fortunately, there are existing programs that encourage people and companies alike to reduce their energy consumption. One primary example is Energy Star, which is administered by the EPA and provides guidance and certifications to companies demonstrating a desire to control and reduce energy usage...”
Go Inside an Industrial Plant That Sucks Carbon Dioxide Straight Out of the Air. MIT Technology Review has the story; here’s the intro: “Carbon dioxide emissions must decrease to nearly zero by 2040 if global warming by the end of this century is to be held to 2 C. But we may well miss that target. A pilot plant started last fall at Squamish, British Columbia, is testing a backup plan: sucking carbon dioxide directly out of the air. Capturing ambient carbon dioxide is a tall order because, for all the trouble it causes, the greenhouse gas makes up just .04 ercent of the air we breathe...”

Alaska Air Flights Using Fuel Made from Fermented (Minnesota) Corn. The Seattle Times has the story; here’s a clip: “…The biofuel on Tuesday’s flights was developed by Gevo, a company based in Englewood, Colo. Gevo produces isobutanol — a form of alcohol — at its fermentation plant in Luverne, Minn., in a manner similar to the longstanding production of ethanol. It converts the alcohol into renewable jet fuel at a biorefinery in Silsbee, Texas. At 1:45 p.m., Alaska Flight 2 from Seattle to Washington, D.C., took off powered by the same fuel mix. Alaska has set a goal to use sustainable aviation biofuel on all flights at one or more of its primary airports by 2020. The challenge is to produce the biofuel on a large scale and at a price similar to regular jet fuel…”

Wanderwell described particularly grueling driving conditions in India and China. She wrote about moments when the team used kerosene in place of gasoline, mixed water and elephant fat for oil, and crushed bananas to collect grease. In 1924, China was also struck by a civil war which made gasoline difficult to come by. She wrote how they had to tow and push the cars through mud and rivers—in Africa, they needed oxen and mules to tow the vehicles…”

The Post these days sometimes seems like a technology company as much as it does a news organization, although the focus is on how technology can serve journalism rather than the other way around. The Post’s website and mobile apps are a pleasure to use; the apps have been designed to serve different audiences depending on whether they are traditional Post readers or are instead interested in a more viral product offered at a lower price and that omits local news…”

Increased Extreme Weather Events Predicted Due to Effect of Climate Change on the Arctic. Here’s the intro to a summary at Common Dreams: “The effects of climate change on the Arctic — including melting ice and sea level rise — may possibly alter weather patterns in the northern hemisphere. These effects could include hotter, drier summers in some areas, wetter summers in other areas, and cold, stormy winters in others, according to studies compiled by the Greenpeace Research Laboratories in the report, “What happens in the Arctic doesn’t stay in the Arctic” which is published today….”
Unabated Global Warming Threatens West’s Snowpack, Water Supply. InsideClimate News has the story; here’s an excerpt: “Low-elevation snowpack across the Rocky Mountains, the Sierra Nevada and the Cascades will disappear in the coming decades if global warming continues unabated, according to a new study. The changes will cause water shortages in the region and dry out forests and grasslands, the study’s authors say. According to the research, the snow line—the altitude above which it snows, and below which it rains—will climb as much as 800 feet in the Colorado Rockies, and 1,400 feet in the Rockies of Idaho and Wyoming by 2100 if greenhouse gas emissions continue at the current rate...”
Climate Change Will Affect Farmers’ Bottom Line. Here’s a clip from a story at phys.org: “…What’s new about the work is that the team used an economic model that allowed them to look across production systems, so they could evaluate farmland values for soybean producers and cattle ranchers alike. The model, knows as the Ricardian approach, also allowed for adaptation on the part of the farmer. “Farmers are smart; you can’t assume that in 100 years they’re going to still be farming corn like they are now,’ Dall’Erba says. “Climate is changing, new practices and new technologies develop, so they may switch to another production system. The Ricardian approach assumes farmers will adapt…”

China Says Important Glacier is Melting Due to Climate Change. Here’s a story excerpt from Reuters: “A glacier that is one of the largest at the source of China’s Yangtze River is fast retreating because of climate change, state media said. The Jianggudiru Glacier on Geladaindong Mountain in a remote part of the western province of Qinghai has shrunk 34 meters (38 yards) over the past six years, Pu Jianchen, a researcher at the Chinese Academy of Sciences, told the Xinhua news agency. The glacier started to shrink slowly in the 1970s, then expanded between 1989 and 1994 before retreating more quickly from 1995, Pu said, Xinhua reported late on Tuesday...”

Is Your House Causing Global Warming? Seeker.com has an interesting post; here’s an excerpt: “...In today’s DNews special, Trace Dominguez considers the matter of air conditioners and other home appliances, in regard to energy usage. Reducing energy waste in the home is a fast and simple way to increase efficiency, save money, and — while you’re at it — confront the single most lethal crisis our species has ever faced. What’s not to like? Let’s start with a little quick math — don’t worry, it only stings for a second: According to the U.S. Energy Information Administration, the average annual energy consumption for a residential home is 15,497 kilowatt-hours (kWh). About one third of U.S. homes still use coal to generate those kilowatts. It takes 1.04 pounds of coal to generate one kilowatt-hour, which also generates 2.13 pounds of carbon dioxide…” (File image: Midwest Energy News).
Ontario To Spend Billions To Fight Climate Change, Offer Incentives. Details via The Sudbury Star: “Ontario’s action plan on climate change will include financial incentives to get cleaner, more efficient cars and trucks on the roads and to convince homeowners and businesses to lower their carbon footprints, The Canadian Press has learned. The plan, scheduled to be released on Wednesday, calls for government spending of $5.9 billion to $8.3 billion on climate change initiatives over the next five years. The money would come from the $1.9 billion the Liberal government expects to raise each year by auctioning off pollution emission credits when Ontario joins a cap-and-trade market with Quebec and California next January...”
Editorial: Cities, Counties Must Deal With “New Normal” of Rain, Floods. Here’s an excerpt of an Op-Ed at the Beaumont Enterprise in Texas: “…Places in Houston have had two “500-year floods” this spring. The city of Brenham has already set a record for its wettest calendar year on record. This week it got more than 19 inches of rain in 48 hours. That’s more than Los Angeles is supposed to get in an entire year. Half of our entire state is under flash flood watch or warning. Keep in mind that all of this has no connection with the “official” hurricane season, which began this week. Our rainfall isn’t cascading in from the Gulf of Mexico. It’s coming inland along the same patterns our parents and grandparents dealt with – only more often, and heavier. After a while, conditions like this aren’t abnormal. They become the new normal, and we have to start adjusting to them...” (File photo: U.S. Coast Guard).
Tropical Storm Colin 2016. Here’s an excerpt from Climate Signals: “Tropical Storm Colin formed five days into the Atlantic hurricane season, just as Tropical Storm Bonnie, which had arrived five days ahead of the season’s official start, dissipated. Colin marks the earliest arrival of the third tropical storm in the Atlantic hurricane season, thanks to unusually warm waters that have helped to fuel the early season storms. Global warming has been found to increase the rainfall associated with hurricanes. In addition seal level rise is elevating the storm surge driven by hurricanes. There is also a significant risk that ocean warming may be directly increasing hurricane intensity...” (Visible loop: WeatherTap).
That 70s Myth – Did Climate Science Really Call for a “Coming Ice Age?” Ars Technica has the story; here’s the intro: “One of the undying, zombie-like arguments against climate change is that you can’t trust climate scientists because they started out making doom and gloom claims about global cooling in the 1970s. But this, along with many other things comedian Dennis Miller has said on late night talk shows, needn’t be taken seriously. By the time fears of an ice age reached the public’s attention, there was a long history of concerns about warming. The idea that burning fossil fuels would warm the planet can be traced back to an 1896 paper by Swedish scientist Svante Arrhenius. In the 1930s, Britain’s Guy Callendar concluded that global warming was already underway. So it seems a bit odd that anyone worried about cooling. What was really going on back in the ’70s—both in science and in the media?…”
