Christmas Cold Wave Coming - Dangers of Hypothermia

Cold Wave Coming - Dangers of Hypothermia

It's all hype, until it happens. Then it's "why wasn't there any warning?" The cold wave arriving in 6 days may last a few weeks; daytime highs in single digits, nights dipping below 0F. Probably not record-territory; we've seen much colder here. Yet potentially one of the 2 or 3 coldest spells of the winter.

Most of us know how to dress in layers to avoid frostbite. Hypothermia, a gradual drop in body temperature, is even more insidious. According to NOAA, most of the 1,300 Americans who die from hypothermia annually are seniors. As we get older our shivering mechanism (which keeps us warmer) tends to breaks down. Throw in reactions to medication and bad circulation, and the risk increases. Symptoms include a body temperature less than 96F, feeling sluggish or not thinking clearly. If in doubt, call a doctor or 911.

A clipper may drop an inch of slush tonight. Enjoy 30s Saturday into Wednesday, because by Christmas weekend highs hold in single digits with lows slipping below 0 F. Herd-thinning cold.

The arrival of bitter air may even spark a plowable snowfall next Thursday!


Christmas Smack. After reaching 30s into Wednesday of next week temperatures drop off into the teens late next week and over the Christmas weekend, with nighttime lows at or near 0F. Not record territory - but cold enough. Twin Cities ECMWF forecast graphic above: WeatherBell.


Dangers of Hypothermia. NOAA has some good reminders as we head into an extended cold wave late next week - the elderly and infants most prone to a slow, and potentially fatal drop in body temperature: "When your body temperature sinks below 96°F, you have hypothermia, a serious health hazard that occurs when body temperature is lowered to much. Get medical attention immediately. Move the victim inside to a heated location and begin warming the center of the body first. If the person is unconscious, administer CPR. Hypothermia can occur in temperatures as warm as 60°F, particularly in water or with if you are outside a long time and not dressed for the weather. Of the approximately 1,300 people the CDCP lists as being killed by hypothermia each year, most are seniors, according to the National Institute of Aging, but some are children and young adults. Everyone needs to be careful. Some medicines, problems with circulation, and certain illnesses may reduce your ability to resist hypothermia. As you age, your body becomes less efficient at letting you know when you are too cold. In addition, older people tend not to shiver effectively, one of the ways the body warms itself up. Remember these tips to help prevent hypothermia:

  • Dress in layers
  • Wrap up well when going outside in the cold.
  • Avoid breezes and drafts indoors.
  • Eat nutritious food and wear warm clothes to ward off winter chill.
  • Wear a warm hat in the winter.
  • Eat hot foods and drink warm drinks several times during the day.
  • If you live alone, ask a family member of neighbor to check on you daily or have a camera installed that a family member can view on their computer.
  • Ask your doctor if any medicine you're taking increases your risk of hypothermia. Drugs that may cause a problem include barbiturates, benzodiazepines, chlorpromazine, reserpine, and tricyclic antidepressants..." 

Clipped Again. The best chance of a couple of inches of snow tonight and Saturday morning comes north of Lake Mille Lacs; maybe some 3-4" amounts in the Red River Valley. MSP metro area may see a coating. 12km NAM guidance: NOAA and Tropicaltidbits.com.


Numbing End to December. The forecast 500mb map above (GFS) reminds me of the "Polar Vortex" winter 4 years ago, when bitter air stalled over Hudson Bay for week after week, month after month. There's no evidence that polar air will stall for an extended period of time, but I'd plan on 2 straight weeks of highs in single digits, maybe low teens southern Minnesota - nights below 0F. It's time.


January Outlook. NOAA's CFSv2 climate model predict a milder than average January for much of the USA, with the exception of far northern states, including Minnesota. Confidence levels are low, but this sure is a colorful map! Source: WeatherBell.



ECMWF Outlook for White Christmas 2017. The map above shows the European model forecast for 1" of snow cover on Christmas morning, December 25. Much of the northern USA should have a white Christmas, but it may be touch and go for Chicago, Des Moines and Kansas City. Map: weather.us.


 

Geminid Meteor Shower Peaks. Details from IMO, The International Meteor Organization: "The Geminid meteor shower is the favorite of most meteor observers as it usually provides the strongest display of the year. On the peak night (December 13/14) between the hours of 1:00 and 2:00am local standard time (LST), an observer located in mid-northern latitudes under clear skies has the opportunity to view at least 75 Geminid meteors. If you watch from a rural setting far from city lights then your counts could exceed 100. If watching from urban locations you will be limited to around 50 meteors during this period. The Geminids are one of the few annual meteor showers that are active all night long..."


Huge Trigger of Winter Injuries: Falls on Snow and Ice. Check out the details from CDC: "Each year, millions of older people—those 65 and older—fall. In fact, more than one out of four older people falls each year, but less than half tell their doctor. Falling once doubles your chances of falling again.
  • One out of five falls causes a serious injury such as broken bones or a head injury.
  • Each year, 2.8 million older people are treated in emergency departments for fall injuries.
  • Over 800,000 patients a year are hospitalized because of a fall injury, most often because of a head injury or hip fracture.
  • Each year at least 300,000 older people are hospitalized for hip fractures.
  • More than 95% of hip fractures are caused by falling, usually by falling sideways.
  • Falls are the most common cause of traumatic brain injuries (TBI).
  • Adjusted for inflation, the direct medical costs for fall injuries are $31 billion annually. Hospital costs account for two-thirds of the total..."

Critical Fire Danger Lingers Over SoCal - Slow Progress on Thomas Fire. Praedictix Briefing: Issued Thursday, December 14th, 2017:

  • Multiple major wildfires continue across parts of southern California Thursday morning, with almost 265,000 acres consumed since last week.
  • An update on the active wildfires:
  • Critical fire danger is expected Thursday into Friday morning across southern California, as wind gusts of 50+ mph will be possible. Red Flag Warnings are in effect into Friday morning across these areas.

Ongoing Wildfires. Four major wildfires continue to burn across southern California this morning. The Thomas Fire has grown to 238,500 acres burned and is 30% contained. Here was the situation on the Thomas Fire from the Cal Fire incident report last night:

Santa Barbara County:  Gusty north to northeast winds will continue to battle with terrain driven winds. In the evening, the offshore flow will prevail and strengthen, as it has each night, amplifying fire activity. Very high fuel loading, critically low fuel moistures, above average temperatures and single-digit relative humidities will continue to support fire growth on the west, east and north sides of the Thomas Fire. Firefighters will remain engaged in structure defense operations, scout for opportunities to establish direct perimeter control along with contingency planning and efforts ahead of the fire front. Fire will continue to threaten the communities of Santa Barbara, Carpinteria, Summerland, Montecito and surrounding areas.

Ventura County: Crews continued to actively engage in suppressing active and small spot fires around the Southeastern portion of the perimeter. Areas currently evacuated are mitigating hazardous conditions. Utility companies continue to assess and mitigate infrastructure that was damaged from the fire so citizens can be safe when returning to these affected areas.

A detailed, interactive map of the fires can be found HERE.


Critical Fire Danger Today. Today will be another day of strong Santa Ana winds across southern California, with low humidity values and wind gusts of 50+ mph. This will lead to a critical fire weather day across the region, as any ongoing or new fires will be able to quickly spread in the favorable fire weather conditions. Gusty winds and low humidity values are also leading to an elevated fire danger in the Colorado River Valley throughout the day.


Critical Fire Danger Continues Into Friday. We will continue to see critical fire weather concerns across southern California into Friday morning, however the strong offshore winds will be on the decrease throughout the afternoon hours. We should also see some higher humidity values at lower elevations as well as we head toward Friday night.


Red Flag Warnings. Due to the continued fire weather conditions - including gusty Santa Ana winds and low humidity values - Red Flag Warnings are in effect across portions of southern California. These warnings in the Los Angeles and San Diego areas are in effect through Friday morning, with warnings through Thursday afternoon for the Colorado River Valley and other portions of southern California, including Imperial. Across these warning areas, winds could gust over 50 mph at times. In the Sierra and Kern County Mountains, the Red Flag Warning goes through Friday evening and is due to low humidity values as winds will be between 5-15 mph.


Wind Advisories In Effect. Wind Advisories are in effect today across portions of California, Nevada and Arizona (including the Los Angeles area) due to the potential of wind gusts up to 50 mph in spots. This wind will help spread any ongoing or new wildfires that spark across the region.


Forecast Peak Wind Gusts. Winds will be stronger at higher elevations as we head throughout the next 24 hours, with wind gusts of 30+ mph expected for areas like Ontario and Riverside. Graphic: NWS San Diego.


Latest Information From The National Weather Service – Los Angeles. Here is more information on the Red Flag Warning areas and expected fire weather over the next couple of days from the National Weather Service office in Los Angeles: “Gusty northeast winds are expected to continue through Friday morning, especially over Ventura and Los Angeles Counties. The greatest concern will be for the mountains of Los Angeles and Ventura Counties, the Santa Clarita Valley, and the Santa Ana wind prone areas of the Ventura County valleys and Oxnard Plain. The strongest winds are expected Thursday into Thursday night, where northeast wind gusts of 40 to 50 mph can be expected for the coast and valleys, with gusts up to 55 mph in the mountains. Relative humidities will continue to remain in single or low teens as well with poor overnight recoveries. The gusty offshore winds, very low relative humidity, unseasonably warm temperatures, and extremely dry fuels will allow the extreme fire danger to continue, with the potential for large fires, rapid fire growth, and extreme fire behavior if ignition occurs. Although there are no Red Flag Warnings issued for Santa Barbara County, there will be local northeast to east winds 15 to 25 mph over the mountains Thursday into Thursday evening, and combined with extremely low humidities will result in elevated fire weather concerns.”


Smoke As Far North As The Bay Area. Due to high pressure, smoke has been drifting across portions of the eastern Pacific. Smoke has even been transported as far north as the Bay Area. Graphic: NWS San Diego.


Smoke Impacts Continue. Poor air quality is once again expected today across the region due to the smoke from the Thomas Fire. This is the near-ground smoke forecast for Noon today.

Unfettered Building, Scant Oversight Add to Cost of Hurricanes In U.S. Reuters investigates: "...Across the country, newer construction in flood-prone areas generated more than $9 billion in claims for structural damage on the cash-strapped flood insurance program between 2000 and 2015. Flood-management authorities say that some of those claims probably never would have been filed had proper building controls and accurate flood maps been in place. “You look at the media images and you see new subdivisions, new strip malls and new buildings with water up to the rooftop. Those are red flags in my mind. Those shouldn’t be happening,” said Paul Osman, floodplain program manager for the Illinois Office of Water Resources. Controlling construction inside flood-prone areas is critical to keeping flood insurance affordable and reducing post-disaster costs, federal officials say..."

Climate Stories....

Scientists Link Hurricane Harvey's Record Rain to Climate Change. A warming atmosphere made the probability of Hurricane Harvey's 50"+ rains as much as 38% more likely, according to 2 new studies highlighted at The New York Times.

Climate Change Made Harvey's Rainfall Three Times More Likely, Scientists Say: From Climate Nexus Hot News: "Climate change made Hurricane Harvey's record-breaking rainfall much worse, scientists reported this week. Peer-reviewed research from the World Weather Attribution initiative, presented Wednesday at the American Geophysical Union conference in New Orleans, found that climate change made the hurricane's rainfall totals 15 percent more intense than normal. Meanwhile, separate research published in the journal Geophysical Research Letters and also presented at AGU found that climate change likely increased Harvey's rainfall by 20 percent, and possibly as much as 38 percent. Harvey's record-breaking rainfall in August totaled 50 inches in some areas of Houston."

Climate Change to Affect City and State Credit Ratings. Here is an excerpt from an Op-Ed from San Antonio's Express-News Editorial Board: "Cities and states, take note. Climate inaction could lower your credit rating. A recent report from Moody’s explains how the rating agency will assess climate change risk for states and cities. Risk indicators include economic activity along the coast, potential for hurricane and other extreme-weather damage, and the number of homes in a floodplain. Moody’s didn’t identify cities in its report, but Texas is one of the states deemed most vulnerable to climate change. Not surprising since Texas has tremendous economic activity along the Gulf Coast and is prone to all sorts of extreme weather across the state. Hurricane Harvey, which slammed into the Coastal Bend before dumping more more than 50 inches of rain on Houston, has caused an estimated $180 billion in damages. Many of the properties damaged were not in designated floodplains, raising questions about whether our mapping and flooding expectations are accurate in light of climate change..."

Warm Arctic is 'New Normal,' Scientists Say: Here's a summary and link to relevant stories from Climate Nexus: "The Arctic is experiencing "unprecedented" warming with a rate of sea ice decline not seen in at least the last 1,500 years, a new government report shows. The National Oceanic and Atmospheric Administration's annual Arctic Report Card, released Tuesday, shows that the region is warming around twice as fast as the rest of the planet. The report also shows that thicker ice lasting through multiple melt seasons only made up 21 percent of total Arctic ice this year, as opposed to 45 percent in 1985. The report states that the Arctic "shows no sign of returning to the reliably frozen region it was decades ago."

How The Pentagon Can Step Up on Climate: From Climate Nexus: "The Department of Defense must do more to prepare its overseas bases for the impacts of climate change, according to a government watchdog. The Government Accountability Office said in a report made public Wednesday that integration of climate adaptation in overseas projects and planning is lacking, finding that only one-third of the plans the office reviewed addressed the impacts of climate change. The Pentagon is receiving some climate policy direction from an unusual sourcePresident Trump on Tuesday signed a nearly $700 billion bill directing defense policy for the upcoming year which calls climate change "a direct threat to the national security of the United States."

Relatively Mild Next 7 Days - Christmas Weekend Goosebump Alert

 
Dribs and Drabs of Snow - Quiet Into Christmas

Is this going to be another one of THOSE winters, where snow lovers grovel, beg & plead for a few lousy inches of Minnesota powder? Not sure, and it's probably a little early to panic. December is, in theory, the second snowiest month of the year. 1981-2010 climate data shows an average of 11.5 inches of snow falls this month. So far the metro area has picked up 3-4 inches.
 
Why? To get a major dumping, prevailing jet stream steering winds aloft need to blow from the southwest, from New Mexico, allowing Gulf moisture to bubble northward - with enough cold air holding in place for snow vs. rain. We just haven't seen this setup, but the pattern may change in January, historically our snowiest month. Or maybe February 4?
 
Lonely snowflakes continue to drift overhead; the next clipper may drop another inch of slush Friday night. Temperatures trend above average through much of next week, and latest guidance takes the core of this next arctic front into New England; just a glancing blow of numbing for Minnesota Christmas week. Not record-setting and not that unusual for late December.



84-Hour Snowfall Potential. NOAA's 12 km NAM shows the heaviest snow bands with Friday's clipper from eastern North Dakota and northern Minnesota into the U.P. of Michigan. Amounts will be enhanced by lake effect into the weekend. Snowfall prediction by Sunday morning courtesy of Tropicaltidbits.com.



Relatively Mild Next 7 Days. And then a reality check sets in; not even close to record-territory - but by Christmas weekend there will be little doubt in your mind that it's late December as nighttime lows flirt with zero. Twin Cities ECMWF guidance: WeatherBell.

Statistical Probability of a "White Christmas" in the Twin Cities: 74% So says NOAA, based on the latest 30-year climate data: "Minnesota. Maine. Upstate New York. The Allegheny Mountains of Pennsylvania and West Virginia. Practically anywhere in Idaho. And of course, the Rockies or the Sierra Nevada Mountains. These are the parts of the Lower 48* where weather history suggests you want to be if you're looking for the best chance of a white Christmas. The map at right shows the historic probability of there being at least 1 inch of snow on the ground in the Lower 48 states on December 25 based on the latest (1981-2010) U.S. Climate Normals from NOAA's National Centers for Environmental Information (NCEI).

Can You Catch a Cold From the Cold? Here's an excerpt of a story from KTHV and 11alive.com: "...Hopkins said while the cold weather doesn’t make you sick and germs do, research suggests that cold weather does create a condition that helps those germs survive. He pointed to a study after study to verify. Publications include Smithsonian Magazine, Pediatric Infectious Disease Journal among other medical studies that all come to the same conclusion. That conclusion is cold temperatures and low relative humidity are favorable to the spread of the flu. And rhinoviruses, which are the most common cause of colds. But what is the science behind your immune system dropping when it is so cold? According to Hopkins, "There are multiple different barriers our body puts up to infections. One is that we have linings in our moist parts of our body – our nose and our mouth. When it gets cold and dry the cells shrink, you may open up the gaps a little bit more between the cells, and you may be able to get more of these viruses through those barriers..."

This is an absolutely incredible snowfall rate. The furious storm dropped another 5 inches in 30 minutes, for a remarkable 15 inches in a brief hour and a half period. In the end, 40 inches of heavy wet snow accumulated in 12 hours..."

Praedictix Briefing: Issued Wednesday, December 13th, 2017

  • Multiple major wildfires continue across parts of southern California Wednesday morning, with over 262,000 acres consumed since last week.
  • An update on the major wildfires:
    • The Thomas Fire continues to grow north of Los Angeles. The fire has now burned 236,000 acres and is 25% contained. The fire is the fifth largest in modern California history, and has cost at least $55.5 million dollars to fight so far. 18,000 structures continue to be threatened by this fire according to Cal Fire. Mandatory evacuations remain in place - here are evacuation maps for Ventura County and for Santa Barbara County. Both Ventura County and Santa Barbara County are keeping their local government pages updated with evacuation orders, road closures, and other relevant information like evacuation shelters.
    • The Creek Fire has burned 15,619 acres and is 98% contained. Inciweb has more information.
    • The Rye Fire burned 6,049 acres and is 100% contained. Cal Fire has more information.
    • The Skirball Fire has burned 422 acres and is 85% contained. The Los Angeles Fire Department has more information.
    • The Lilac Fire has burned 4,100 acres and is 95% contained. Cal Fire has more information.
    • The Liberty Fire burned 300 acres and is 100% contained. The city of Murrieta has more information.
    • Elevated fire danger continues today across southern California, with wind gusts up to 40 mph expected. Critical fire danger is expected Thursday, as wind gusts increase to 50 mph. Red Flag Warnings and Fire Weather Watches are in effect through Thursday across these areas.
  • In the Great Lakes region, a clipper system will bring the potential of heavy snow today into Thursday to some areas. Detroit is expected to see over a half a foot of snow. Winter Storm Warnings are in effect.

Ongoing Wildfires. Four major wildfires continue to burn across southern California this morning. The Thomas Fire has grown to 236,000 acres burned and is 25% contained. Here was the situation on the fire from the Cal Fire incident report last night:

Extreme fire behavior oscillating between wind - and plume - driven runs will continue to hamper control efforts. Firefighters will remain engaged in structure defense operations and scout for opportunities to establish direct perimeter control. Fire will continue to threaten the communities of Santa Barbara, Carpinteria, Summerland, Montecito and surrounding areas. Fireline construction to the north of these communities will continue. Improvement of the Camino Cielo for use as a control line will continue. Contingency groups will improve existing fuel breaks in Santa Barbara County, particularly in the areas of Windy Point and Foothills. Direct line construction, where possible, will continue on the northern side of the fire as well as the establishment of secondary line. In previously burned areas, continued mop -up operations will occur in order to expedite repopulation efforts. The area between Fillmore and Ventura along Highway 126 will remain in patrol status. Strengthening of firelines around the Ojai Valley area will continue, as communities will remain threatened by resi dual hot spots. In the east, outlying areas of Fillmore will remain threatened. Fire personnel will work to construct direct fireline with the support of aerial resources where possible on the east side of the fire. Scouting for establishment of indirect fireline will continue where needed.

A detailed, interactive map of the fires can be found HERE.


Elevated Fire Danger Continues Today. Santa Ana winds continue across southern California today, with low humidity values and wind gusts up to 40 mph. This will lead to another day of elevated fire weather concerns across the region. Elevated fire concerns extend into the Sierra as well, mainly due to low humidity values being transported west from the Great Basin. Wind speeds will generally be around 10 mph in the Sierra.


Critical Fire Danger Thursday. The weather pattern changes as we head into Thursday as a system moves into Arizona. However, this will strengthen the winds across southern California Thursday. Wind gusts will be up to 50 mph across the region and that - combined with low humidity values - will lead to critical fire weather conditions.


Red Flag Warnings And Fire Weather Watches. Due to the continued fire weather conditions - including gusty Santa Ana winds and low humidity values - Red Flag Warnings are in effect for:

  • The Los Angeles/Ventura County Mountains, Santa Monica Mountains and Santa Clarita Valley through Friday morning. In these areas, winds will gust to 40 mph today and to 50 mph Thursday.
  • Parts of the Sierra Nevada (including Yosemite) and Kern County Mountains through this evening. In these areas, the main concern is the low humidity values that would allow fires to quickly spread.

Fire Weather Watches are in effect Thursday into Thursday Night for the Los Angeles and Ventura county coasts, the San Fernando Valley, the Colorado River Valley and parts of San Bernardino, Riverside, Orange and San Diego counties. Wind gusts are expected to be between 40-50 mph tomorrow, with occasional gusts to 65 mph across southern California.


Latest Information From The National Weather Service – Los Angeles. Here is more information on the Red Flag Warning areas and expected fire weather over the next couple of days from the National Weather Service office in Los Angeles: “Gusty northeast winds are expected to continue through much of this week, especially over Ventura and Los Angeles Counties. Relative humidities will continue to remain in single or low teens as well with poor overnight recoveries. The gusty offshore winds, very low relative humidity, unseasonably warm temperatures, and extremely dry fuels will allow the extreme fire danger to continue. The greatest concern will be for the mountains of Los Angeles and Ventura Counties, the Santa Clarita Valley, and the Santa Ana wind prone areas of the Ventura County valleys and Oxnard Plain. Gusts up to 30 to 40 mph can be expected through Wednesday, then increase to 40 to 50 mph by early Thursday. These conditions will bring the potential for large fires, rapid fire growth, and extreme fire behavior if ignition occurs. Although there are no Red Flag Warnings issued for Santa Barbara County, there will be local north to northeast winds 15 to 25 mph around the hills above Montecito over the next couple of evenings bringing some elevated fire concerns.”


Smoke Impacts Continue. Poor air quality is once again expected today across the region due to the smoke from the Thomas Fire. This is the near-ground smoke forecast for Noon today.


Heavy Great Lakes Snow. A clipper system moving through the upper Midwest and Great Lakes over the next 24 hours will produce the potential of heavy snow as it moves through. Snow accumulations of 6-9” will be possible from Green Bay, WI, across central Michigan, including Detroit, by Thursday morning. Areas like Detroit, Cleveland and Pittsburgh will likely see impacts to the evening commute due to the snow.


Advisories And Warnings. Due to the potential of heavy snowfall amounts as this clipper moves through, Winter Storm Warnings have been issued for parts of Michigan, including Detroit.

The Loss of Arctic Sea Ice Cover Could Affect Millions Worldwide. Turns out what happens in the Arctic doesn't stay in the Arctic. A story at Futurism connects the dots: "...Far from just being bad news for polar bears or vulnerable island chains, melting Arctic sea ice caps can affect areas a long way from the Arctic region, bringing not only higher sea levels, but also severe drought. This may be the case for California, which could see its already extreme lack of water getting worse in the coming decades, according to researchers at the Lawrence Livermore National Laboratory. In a study published on November 5 in Nature Communications, climatologist Ivana Cvijanovic and her team found that shrinking glaciers in the Arctic can modify atmospheric temperatures over the tropical Pacific. In turn, this heat imbalance can push rain-rich clouds away from California towards Alaska and Canada..."

Alaska Weather Service Cuts Balloon Launches Due to Staffing. U.S. News has an update on a development that may, in theory, impact forecast accuracy thousands of miles downwind, over the Lower 48 states: "Workers at 13 Alaska sites are supposed to release balloons twice a day that collect data on temperature, pressure and wind, but the National Weather Service has reduced weather balloon launches in rural Alaska, affecting the quality of forecasts. Launches have been limited in recent years by staffing shortages and by an overtime policy change in August, the Fairbanks Daily News-Miner reported . The Weather Service has launched 28 percent fewer balloons at six of the remote sites in order to keep employees to a 40-hour work week. The loss of any input data affects weather models, but the degree it hurts the accuracy of forecasts isn't easy to quantify. The Weather Service supplements data from weather balloons with data from satellites, Weather Service Alaska Region Director Carven Scott said..."

In response, the intellectuals I follow tweeted something like: “these foolish people! Don’t they know how good they have it! They should be happy!! What’s wrong with them?!” Their words dripped with the strange hallmark of what passes for thought today: hubris, arrogance, pride, and derision. Fascism, authoritarianism, and tyranny can only really arise when our institutions fail, and among the most important of these is the way we think. It’s no overstatement to say today that thought itself has failed — witness daily the constant, perpetual surprise outrage of pundits and intellectuals, whose inability to explain or predict the world anymore is expressed in a furious anger which soon turns to disdain..."

216 Companies on the Fortune 500 List Were Founded by Immigrants or Their Children. Here are a couple of clips from Quartz: "...Of the companies that made the list in 2017, 43% were founded by an immigrant or the child of an immigrant, according to research from the Center for American Entrepreneurship. The  share of immigrant founders in technology is even higher, 45%—though there are immigrant entrepreneurs are represented in every sector… People born in other countries and their children have continued to feed the Fortune 500 list in more recent decades. Apple founder Steve Jobs, the son of a Syrian immigrant, and Russia-born Sergey Brin from Google—and its parent Alphabet—are among the most famous. But there are other relatively new companies with immigrant ties. Marc Randolph, one of Netflix’s founders, is the son of an Austrian immigrant. Sol Barer, a German immigrant, helped start biotech firm Celgene…"


How Tech Companies Could Keep the Workforce Alive. Think your job is safe from automation and AI? A story at The Atlantic caught my eye: "...Jobs in industries such as food services, transportation, and retail trade are at high risk of being automated, forcing workers to gain new skills to compete for well-paying jobs. From Google’s self-driving cars to Apple’s communication technology to Amazon’s retail model, automation is becoming more and more pervasive. As communities across the U.S. witness growing gaps between the skills that workers have and the ones that employers need, workers will need training. Debate about how to prepare workers for the future has largely focused on what educators and employers are doing and could do more of..."

Google's True Origin Partly Lies in CIA and NSA Research Grants for Mass Surveillance. Lovely. Quartz has the story: "Two decades ago, the US intelligence community worked closely with Silicon Valley in an effort to track citizens in cyberspace. And Google is at the heart of that origin story. Some of the research that led to Google’s ambitious creation was funded and coordinated by a research group established by the intelligence community to find ways to track individuals and groups online. The intelligence community hoped that the nation’s leading computer scientists could take non-classified information and user data, combine it with what would become known as the internet, and begin to create for-profit, commercial enterprises to suit the needs of both the intelligence community and the public. They hoped to direct the supercomputing revolution from the start in order to make sense of what millions of human beings did inside this digital information network. That collaboration has made a comprehensive public-private mass surveillance state possible today..."


For the Good of Society - and Traffic - Delete Your Map App! So says the author of a story at nymag.com: "...Bayen points out that this is sort of a gigantic version of the prisoner’s dilemma. “If everybody’s doing the selfish thing, it’s bad for society,” says Bayen. “That’s what’s happening here.” Even though the app makes the route quicker for the user, that’s only in relation to other drivers not using the app, not to their previous drives. Now, because everyone is using the app, everyone’s drive-times are longer compared to the past. “These algorithms are not meant to improve traffic, they’re meant to steer motorists to their fastest path,” he says. “They will give hundreds of people the shortest paths, but they won’t compute for the consequences of those shortest paths...”


Family Sends the Most Awkward Christmas Cards for 15 Years, and It's Too Funny. After seeing this post at Bored Panda I have to agree: "If you think you’ve already seen the funniest family Christmas card of the season, think again. Every year since 2003, the Bergeron family has been ringing in the holidays by producing the most clever and hilarious greeting cards we’ve ever seen, and just like the snow outside, they’re showing no signs of stopping. Mike Bergeron, his wife Laura, and their two daughters known online as ‘Gigi’ and ‘Juju’ have made an annual tradition out of the refreshingly original photoshoots, and each December, they choose a new knee-slapping theme. Whether they draw on pop culture, local culture, or embarrassingly awkward family cards of yore, they always seem to pull it off as a team. Special credit is due, of course, to the JC Penney Portrait Studio, which has seen them all the way from ‘white trash Christmas’ to a full drag ensemble..."


Andrew Zimmern Heads Up Minneapolis Food Hall. GoMN has the tantalizing details: "Minnesota's culinary king has signed on as the first tenant of The Dayton's Project – a $250 million makeover of the historic Dayton's building on Nicollet Mall that, when finished, will include offices, retail stores, a gym, a library and the food hall. According to a press release from developers, The Dayton's Food Hall and Market will be a "mix of well-known food vendors, local treasures, fresh food purveyors, and food makers creating a market that will be the first of its kind in the Twin Cities...Zimmern is hoping to create a food adventure similar to many European food halls and markets, where visitors can sample food from local vendors and shop for things like fresh meat and seafood, artisanal cheeses and fresh baked goods from local purveyors..."


December 14, 1996: Snowfall exceeding one foot is reported from south central Minnesota through portions of the Twin Cities metropolitan area. Some of the higher snow totals include 15 inches at Rockford, 14 inches at Cedar and North Branch, 13 inches at Stewart and 7 to 10 inches across the central and southern parts of the Twin Cities metropolitan area.

December 14, 1933: A severe ice storm hits southeast and central Minnesota.

Scientists Link Hurricane Harvey's Record Rain to Climate Change. A warming atmosphere made the probability of Hurricane Harvey's 50"+ rains as much as 38% more likely, according to 2 new studies highlighted at The New York Times.

Climate Change to Affect City and State Credit Ratings. Here is an excerpt from an Op-Ed from San Antonio's Express-News Editorial Board: "Cities and states, take note. Climate inaction could lower your credit rating. A recent report from Moody’s explains how the rating agency will assess climate change risk for states and cities. Risk indicators include economic activity along the coast, potential for hurricane and other extreme-weather damage, and the number of homes in a floodplain. Moody’s didn’t identify cities in its report, but Texas is one of the states deemed most vulnerable to climate change. Not surprising since Texas has tremendous economic activity along the Gulf Coast and is prone to all sorts of extreme weather across the state. Hurricane Harvey, which slammed into the Coastal Bend before dumping more more than 50 inches of rain on Houston, has caused an estimated $180 billion in damages. Many of the properties damaged were not in designated floodplains, raising questions about whether our mapping and flooding expectations are accurate in light of climate change..."

Warm Arctic is 'New Normal,' Scientists Say: Here's a summary and link to relevant stories from Climate Nexus: "The Arctic is experiencing "unprecedented" warming with a rate of sea ice decline not seen in at least the last 1,500 years, a new government report shows. The National Oceanic and Atmospheric Administration's annual Arctic Report Card, released Tuesday, shows that the region is warming around twice as fast as the rest of the planet. The report also shows that thicker ice lasting through multiple melt seasons only made up 21 percent of total Arctic ice this year, as opposed to 45 percent in 1985. The report states that the Arctic "shows no sign of returning to the reliably frozen region it was decades ago."

To Test for Climate Disasters: Break, Burn and Throw Stuff. The New York Times reports on how the insurance industry is preparing for a new generation of super-storms, extreme weather events and natural disasters.


EXTREME WEATHER: More perspective and context from Climate Nexus Hot News: How much did climate change affect California's wildfires? Depends on where you are (Vox), why are California’s wildfires so historic? For starters, a diablo is at work (Washington Post $), a year punctuated by tragedy (WSJ $), this city in Alaska is warming so fast, algorithms removed the data because it seemed unreal (Washington Post $), from floods to fires, US weather went to extremes in 2017 (USA Today)


Did Climate Change Worsen the Southern California Fires? A warmer, drier climate was one of multiple reasons why the fires have been so bad, according to a story at The Atlantic: "...The answer isn’t as clear-cut as it was this summer, when drought- and heat-stoked fires raged across the Rockies and Pacific Northwest. Instead, a mix of forces are driving the fires in Southern California, and only some of them have a clear connection to global warming. “These fires are not immediately emblematic of climate change,” said John Abatzoglou, an associate professor of geography and climate at the University of Idaho, in an email. “Yes, California did have the warmest summer on record. But the big anomaly here is the delay in the onset of precipitation for the southland that has kept the vegetation dry and fire-prone.” In other words, late-fall and winter rains would normally end California’s fire season in November. Because those rains haven’t yet arrived, the blazes continue..."


Judges Push Trump Lawyers in Kids' Climate Suit Hearing: From Climate Nexus Hot News: "Federal judges expressed doubt on Monday at the Trump administration's attempt to toss out a lawsuit brought against the US government by a group of 21 young people suing over climate change. The three-judge panel of the 9th Circuit Court of Appeals in San Francisco heard arguments from the Trump administration, which had made a rare request for the appeals court to halt the Juliana v. United States case, which is scheduled to go to trial in February. While administration lawyers argued that the "unprecedented" case would create a "constitutional confrontation" if allowed to proceed, multiple outlets report that the judges' line of questioning seemed to indicate that they will allow the case to move forward. "If we don’t stop climate change, I might not have a home when I’m older," 10-year-old plaintiff Levi Draheim, a Florida resident, told the court. "That’s why our case has to go to trial."

Wind Energy Is Supposed to Help Fight Climate Change. It turns Out Climate Change is Fighting Back. A tortured headline, sure, but the gist of the article at The Washington Post: a rapidly changing climate may be changing where wind power works best over time: "...But the second study, published Monday in Nature Geoscience and apparently the first comprehensive look at wind energy resources under climate change, projects forward to the future using 10 climate change models. And it finds more of the same across the mid-latitudes of the Northern Hemisphere — a key area for wind energy installation from the United States to Europe to China — even as under some scenarios, the models show a growth of wind resources in the tropics and the Southern Hemisphere. “What we found is that global warming will reduce the wind energy resource across much of the Northern Hemisphere, especially in the central U.S.,” said Karnauskas, who conducted the work with university colleagues Julie Lundquist and Lei Zhang..."
