Touch of October in Late November - Extended Outlook Calls for Leftovers

Another Thing To be Thankful For: Quiet Weather

A Gastrointestinal Advisory has just been issued. The forecast calls for a 2 inch accumulation of turkey on plates by afternoon; some salting may be necessary. Forks will plow into towering mashed potato drifts. Watch for showers of hot gravy, and cranberry sauce will leave some side dishes slippery. Am I stuffing too much into this outlook? The extended outlook calls for pie, bulging refrigerators, a nap and leftovers. Not necessarily in that order.

Thanksgiving weather in the Twin Cities can be all over the map, quite literally. From 62F in 1922 to -18F in 1880 to 5 inches of snow in 1970.

If the sun stays out for a few hours today we should top 40F; a few degrees above average. A southwest breeze tugs the mercury close to 50F tomorrow, before a few afternoon rain showers herald the approach of a slightly-cooler-front. Minor miracle: the weekend looks dry with no problems getting home on Sunday.

After flirting with 50F again Monday temperatures cool off next week - but nothing arctic in sight. Models hint at a rain-snow mix Wednesday and Thursday. The flow looks more Pacific than Canadian into early December.






Relatively Mild November Finish. After a numbing start more of a Pacific (than Canadian) flow lingers into early next week with high temperatures in the Twin Cities pushing 50F Friday; again Monday of next week. At some point we'll get a belt of frigid air, but December will probably start out milder than average. ECMWF guidance: WeatherBell.

Storm Potenntial Midweek. European (ECMWF) model runs show a storm pushing across the Midwest Wednesday into Thursday with rain possibly ending as a little wet snow. Right now it doesn't look like we'll have the deep layer of cold air required for a significant accumulation. Forecast valid 1 am Thursday courtesy of WSI.

December 6: Modified Pacific Air. After a few days at or just above 50F temperatures will cool off the first week of December, but nothing frigid is brewing.


Unstable Ice. With temperatures generally warming in the days to come (40s and low 50s across much of central and southern MInnesota Friday - agaiin Monday and Tuesday of next week) ice on area lakes and ponds will become sketchy and potentially dangerous. Be careful out there.


Fleeting Snow Cover. According to NOAA, there is still 2-6" of snow on the ground over the Arrowhead and far northern MInnesota, but snow cover is now spotty and minimal over central counties.

Best and Worst Times to Travel Over Thanksgiving? GoMN has the dirty details: "Minneapolis (and St. Paul, we assume) is among the cities referenced, with Google's data showing that the worst time to set off for your Thanksgiving weekend is at 4 p.m. on Wednesday. The best time, it says, is at 5 a.m. on Thanksgiving morning ... great, thanks for that Google. Traffic levels rise in the hour or two before 4 p.m. and drop relatively sharply after 6 p.m., so if you leave after 6 there's a good chance you won't be too delayed…As for coming home after Thanksgiving, Google suggests the best time traffic-wise to re-enter the Twin Cities is 4 a.m. Friday (again, thanks Google). While that is pretty unrealistic, the time you're looking to avoid is 3 p.m. Friday afternoon. AAA predicts that just over 50 million Americans will take to the roads for journeys of longer than 50 miles on Thanksgiving – the highest number since 2005…"

Paid Vacation for Extreme Weather? Get ready for "climate leave", according to a story at The Columbian: "Even the workplace has to adapt to the warming world. As climate change creates more intense storms, companies have started preparing for work disruptions due to extreme weather. In a sign of the times, Fog Creek, a software company based in New York City, recently announced it would provide up to five days of paid “climate leave” for employees who can’t work because of extreme weather events. If there’s a declared state of emergency, the company will give affected employees even more time. During previous hurricanes, wildfires and other natural disasters, the company let employees take time off on a case-by-case basis. One Miami-based employee had to evacuate during Hurricane Irma, and Sandy displaced most of the company back in 2012. Throughout the storms, Fog Creek continued to pay the staff..."


As World Turns More Slowly, We Face Earthquake Boom, Scientists Warn. This one had me scratching my head (which I'm doing more often these days) but just in case they're right, here's a clip from HuffPost: "...It seems contradictory, but a minuscule slowing of the Earth’s rotation over years, which can extend the length of a day by a millisecond or more, appears to be linked to an increase in major quakes.  Roger Bilham of the University of Colorado and Rebecca Bendick of the University of Montana say that historical data since 1900 clearly reveal a “strong” link between major global earthquake activity and a slight slowing of the Earth’s rotation for five or six years. That has occurred approximately every 32 years. If that pattern continues, the number of powerful quakes in the coming year could triple, according to the researchers. “On five occasions in the past century, a 25 [to] 30 percent increase in annual numbers of  earthquakes [of a magnitude 7.0 or greater] has coincided with a slowing in the mean rotation velocity of the earth,” the scientists noted in a research abstract..."

When Will the Earth Try to Kill Us Again? A little light reading, courtesy of Ars Technica. Here's a clip: "...This isn’t your regular Vesuvius/St. Helens/Hawaii style volcanism.

By 2050, There Will Be More Plastic in the Ocean Than Fish. A story at Big Think got me thinking: "...How prevalent is the plastic problem? Consider there are a number of garbage patches throughout the world. Over eight million tons of plastic enter the waste stream each year. 91% of it isn’t recycled. That means it sits in landfills and eventually makes its way to the ocean. It’s also long-lived. Plastic takes 400 years to break down. There’s estimated to be 6.3 billion metric tons of plastic waste on Earth. By the middle of this century ton for ton, they’ll be more plastic in the ocean than fish. All of this we’ve known. What we haven’t know until now, is how deep this oil-based refuse has sunk.  We all must pitch in to help stem the flow of plastics into the ocean. What can you do? First, purchase clothing that’s made of 100% natural material, such as cotton, silk, hemp, wool, linen, or cashmere..."

New Study Reaches a Stunning Conclusion About the Cost of Solar and Wind Energy. ThinkProgress has the article: "In one of the fastest and most astonishing turnarounds in the history of energy, building and running new renewable energy is now cheaper than just running existing coal and nuclear plants in many areas. A widely-used yearly benchmarking study — the Levelized Cost of Energy Analysis (LCOE) from the financial firm Lazard Ltd. — reached this stunning conclusion: In many regions “the full-lifecycle costs of building and operating renewables-based projects have dropped below the operating costs alone of conventional generation technologies such as coal or nuclear...”

China is Winning Electric Cars "Arms Race". So says an article at CNN Money: "China is outmaneuvering the U.S. and other countries in the global scramble for a vital element for electric cars. As demand for the vehicles surges, Chinese companies have been doing deals around the world to secure supplies of lithium, a silvery-white metal mined from rocks in Australia and brine pools in South America. China is the top market for electric and hybrid cars, accounting for roughly half of global sales, and the government is pushing the development of the industry within its borders. That calls for a lot of lithium, a key component of the vehicles' batteries..."


London Buses Being Powered by a New Fuel: Coffee. No mention of whether the buses run faster.  Here's an excerpt from CNN.com: "British startup bio-bean has partnered with Shell (RDSB) and Argent Energy to create a coffee-based biofuel that will be used in London's diesel buses. The company has produced 6,000 liters of coffee oil for the pilot project with London's transportation authority -- enough to help power the equivalent of one city bus for a year. "It's a great example of what can be done when we start to reimagine waste as an untapped resource," bio-bean founder Arthur Kay said in a statement. The startup collects used coffee grounds from cafes, restaurants and factories, and transports them to its recycling facility. There, the grounds are dried before coffee oil is extracted. The coffee oil is then blended with other fuels to create B20 biofuel, which can be used in diesel buses without modification.

Macy's Has a Plan to Survive the Retail Apocalypse. Bloomberg has the story: "...Back-office efficiencies, vendor synergies, and national marketing budgets may have excited investors, but none of that mattered much to customers. A few years later, Lundgren attempted to “localize” merchandise in stores that he’d essentially just centralized and personalize stores whose decades-old identities he’d just erased. He called the strategy “My Macy’s.” “One of the five greatest retail mistakes in history was Macy’s buying all that it did,” says Nick Egelanian, president of SiteWorks Retail Real Estate Services, a retail consulting firm. “Macy’s bought department stores that were already failing. They were buyers when they should have been sellers. If they were going to buy, then they had to reinvent, but they didn’t...”

Want to Live Longer? Get a Dog. But we knew that already, right? CNN reports: "The benefits that come with owning a dog are clear-- physical activity, support, companionship -- but owning a dog could literally be saving your life Dog ownership is associated with a reduced risk for cardiovascular disease and death, finds a new Swedish study published Friday in the journal Scientific Reports. For people living alone, owning a dog can decrease their risk of death by 33% and their risk of cardiovascular related death by 36%, when compared to single individuals without a pet, according to the study. Chances of a heart attack were also found to be 11% lower. Multi-person household owners also saw benefits, though to a lesser extent. Risk of death among these dog owners fell by 11% and their chances of cardiovascular death were 15% lower. But their risk of a heart attack was not reduced by owning a dog..."


Happiest Cities in America, According to New Research. Here are a couple of nuggets from a CNN.com story: "...Boulder, Colorado, is the happiest city in America. Second is Santa Cruz, California, and Charlottesville, Virginia, is third. (You can find the rest of the list at NationalGeographic.com and in the cover story of the November issue of National Geographic magazine.) In these places, people feel safe and secure, have a sense of purpose and have joy in their day-to-day lives. In these communities, residents are able to weave together the essential strands of happiness: pride, pleasure and purpose...Our data show that people tend to be happiest close to water (lakes, ocean, rivers) and when they have access to nature, green spaces, and fruits and vegetables..."


These are the Happiest Cities in the United States. The Twin Cities ranks #22, one of only two "Happy Cities" in the Midwest. This is the cover story for National Geographic's November issue referenced above; here's an excerpt: "...National Geographic’s list of the 25 Happiest Places in the United States includes cities from Ann Arbor to Austin, San Diego to Charlottesville. At the bottom of the index (not included in our list) are America’s least-happy places, according to the study: Charleston, West Virginia; Fort Smith, Arkansas; and Hickory-Lenoir-Morganton, North Carolina. Research indicates that the variabilities of place play an important role in whether locals feel happy. In happier places, according to Buettner, locals smile and laugh more often, socialize several hours a day, have access to green spaces, and feel that they are making purposeful progress toward achieving life goals. For our index, it tracked factors that are statistically associated with doing well and feeling well; these include feeling secure, taking vacations, and having enough money to cover basic needs..."

Since 2010, Sad Songs Have Become Less Common All Over the World. Quartz reports: "Researchers from Indiana University-Bloomington performed analyzed about 90,000 songs in English from different genres (such as classic rock, pop, punk, metal, R&B, and religious) written by musicians around the world, published since 1950, and posted on ultimate-guitar.com. They assessed the chords used in the songs and judged the emotional valence of lyrics using a common social-science scale that rates 222 different words on a scale of 1-9 in terms of their emotional positivity. “Love” for example is a high-valence word that rates a 9, while “pain” is a low-valence word that rates a 1. It turns out that worldwide, moody tunes are on the decline. Low-emotional-valence songs—tunes with negative lyrics—became increasingly common from 1950 to 2010, but since have been less commonly written. The researchers didn’t offer an explanation for the apparent increase in lyrical positivity, saying only that more study is needed..."

Climate Stories...

Climate Change Brings Bigger Storms, Increased Rainfall: From Climate Nexus Hot News: "Increased warming will encourage wetter, wilder and more frequent thunderstorms, according to new research. A study published Monday in the journal Nature Climate Change projects that under a business-as-usual emissions scenario, larger storms will help the total amount of rainfall in the US South increase by 80 percent by the end of the century, while the Southwest will see a 60 to 70 percent increase. "We see increases that are beyond our expectations...far beyond our expectations," the study's lead author Andreas Prein told the AP. “It looks everything that can go wrong does go wrong concerning flooding." (AP)


New Study: Larger, More Intense U.S. Storm Complexes on the Way. These are the storm that growl overhead many summer nights, and there's a chance they may get supersized over time, according to new studies highlighted by Bob Henson at Weather Underground's Category 6: "...The mammoth clusters of thunderstorms known as mesoscale convective systems (MCSs) could dump up to 80% more water across North America by late this century, according to a study published Monday in Nature Climate Change. The study, “Increased rainfall volume from future convective storms in the U.S.,” found that increased atmospheric moisture in a warming climate will help lead to a 15 – 40% increase in peak MCS rainfall rates, along with a 20 – 70% jump in the rainfall area. Together, these lead to a 30 – 80% boost in the total hourly volume of rain deposited by a typical MCS. "The combination of more intense rainfall and the spreading of heavy rainfall over larger areas means that we will face a higher flood risk than previously predicted," said the study team, led by Andreas Prein (National Center for Atmospheric Research). “Current investments in long-lived infrastructures, such as flood protection and water management systems, need to take these changes into account to improve climate adaptation practices...”

Weird Weather We're Having. Can We Move On From Climate Change Denial? Here's an excerpt of an Op-Ed at New Richmond News in western Wisconsin that caught my eye: "...Climate change is a real threat to humans and all forms of life on Earth. There is a strong consensus in the scientific community that humans have affected the climate, that changes are accelerating and that they pose an existential threat. There is no doubt that sea level rise is occurring and that severe weather events are becoming more frequent and extreme. Hurricanes Irma, Harvey and Maria, raging wildfires out west, record heat in California, devastating forest fires in Europe, a hurricane battered Ireland and record monsoons in south Asia all occurred this year. Here in Wisconsin, the Birkebiner ski race was cancelled this year for lack of snow. We've had five 100-year floods and one 1,000-year flood in Wisconsin in the last six years. Global temperatures have hit record highs for each of the last three years. The carbon dioxide concentration in our atmosphere is now at 407 parts per million, its highest level in at least 800,000 years..."

Doomsday on Ice. What do we really know about the rate of Antarctic glaciers in the past, and what it means in today's rapidly warming world? Here's an excerpt of a story from Eric Holthaus at Grist: "...The ocean floor gets deeper toward the center of this part of Antarctica, so each new iceberg that breaks away exposes taller and taller cliffs. Ice gets so heavy that these taller cliffs can’t support their own weight. Once they start to crumble, the destruction would be unstoppable. “Ice is only so strong, so it will collapse if these cliffs reach a certain height,” explains Kristin Poinar, a glaciologist at NASA’s Goddard Space Flight Center. “We need to know how fast it’s going to happen.” In the past few years, scientists have identified marine ice-cliff instability as a feedback loop that could kickstart the disintegration of the entire West Antarctic ice sheet this century — much more quickly than previously thought. Minute-by-minute, huge skyscraper-sized shards of ice cliffs would crumble into the sea, as tall as the Statue of Liberty and as deep underwater as the height of the Empire State Building. The result: a global catastrophe the likes of which we’ve never seen..."

Simple but Powerful Ways to Reduce Carbon Emissions. Here's an excerpt from an article at Press-Citizen: "...Food waste is responsible for 8 percent of all climate emissions.  A third of all food raised or prepared does not make it to our dinner tables. Imperfect-looking fruits and vegetables are rejected by manufacturers and consumers, and are left to rot in huge warehouses or on grocery shelves. Restaurants serve massive portions of food that are often left uneaten by the customer and immediately thrown into the garbage. According to a recent report, the energy that goes into the production, harvesting, transporting and packaging of wasted food generates more than 3.3 billion metric tons of carbon dioxide. If food waste were a country, it would be the world's third-largest emitter of greenhouse gases, behind the U.S. and China..."

November Ends on Relatively Mild Note - Dream Forecast for Thanksgiving Travelers

A Dream Forecast for Thanksgiving Travelers

After the coldest start since 1995, November shows signs of mellowing a bit. ECMWF (European) model guidance predicts 50-degree warmth Friday; again Monday and Tuesday of next week. A lack of snow and a persistent southwest breeze increases the odds we'll be 10-15F warmer than average into next week.

It could be different, of course. On this date in 1996 half a foot of snow delighted weary commuters in the Twin Cities. On this date in 1880 the Weather Bureau in Minneapolis reported a crisp -6F.

So far seven tenths of an inch of snow has fallen since September 1. Normal snowfall as of November 22 is closer to 6 inches.

No newscast-leading storms are brewing, but a storm rippling aloft may spark an inch or two of slush over northern Minnesota today; a few slick roads into central counties by afternoon. The mercury mellows to 40F on Thanksgiving Day with a risk of light jackets on Friday; hints of October spilling into early next week.

According to NOAA, 2017 is Earth's third warmest year on record, trailing only 2015 and 2016. NASA: 16 of the 17 warmest years since 2001.


Unstable Ice. With temperatures generally warming in the days to come (40s and low 50s across much of central and southern MInnesota Friday - agaiin Monday and Tuesday of next week) ice on area lakes and ponds will become sketchy and potentially dangerous. Be careful out there.


Touch of October. A numbing start gives way to an almost reasonable finish to the month of November with 40s and a low 50s through the end of the month for the Twin Cities, according to ECMWF. Source: WeatherBell.


2 Weeks Out: More Pacific Than Canadian. A mild bias may spill into at least the first week of December with strong west-to-east winds aloft keeping the coldest air north of the USA - for now.


Fleeting Snow Cover. According to NOAA, there is still 2-6" of snow on the ground over the Arrowhead and far northern MInnesota, but snow cover is now spotty and minimal over central counties.

Earliest Date of First Snow? Curious about when the first snowy coating shows up across the USA? NOAA's climate.gov site has an interactive site that's worth taking for a quick test drive: "By the calendar, winter is still a month away. For many of us, though, winter starts with the first snow of the season. By that definition, this map shows the earliest first day of winter recorded at thousands of U.S. stations during their period of operation. Zoom in and click on a dot to find out the earliest date snow has fallen in your neighborhood based on these station histories. As we've published about before in the Beyond the Data blog, snow observations are among the most hit and miss in terms of the completeness of daily histories. These locations are a subset of the complete Global Historical Climatology Network that met various quality controls for reasonableness and completeness of snow cover.  Most stations have at least 20 years of data. A few have a shorter history, but are otherwise of good quality (e.g., little to no missing data)..."


This New Satellite Could Produce the Most Accurate Weather Predictions Yet. The Los Angeles Times has more information on the new JPSS-1 polar orbiting satellite: "...Once JPSS-1 makes it into orbit, its suite of five state-of-the-art instruments will collect the most high-resolution observations yet of our planet’s atmosphere, land and oceans, NOAA officials said. “These instruments are so precise that they can measure temperatures to better than one-tenth of a degree in the entire atmosphere, from the Earth’s surface up to the edge of space,” said Greg Mandt, director of the JPSS program for NOAA. The data these sensors collect will be fed into weather prediction models in almost real time. Ultimately, it will inform the seven-day forecasts you see when you hit the weather app on your phone, or turn on the morning news to decide whether or not to grab an umbrella. JPSS-1’s observations will also help forecasters predict and study major weather events and allow them to better advise communities about when they need to evacuate because of a hurricane or whether a school or workplace should call a snow day..."

Disaster Claims Soar in Year of Calamities. 15 separate billion-dollar disasters, nationwide, so far in 2017, tying the all-time record set in 2011. Here's an excerpt of a Washington Post story at sentinelsource.com: "The number of Americans registered for federal disaster aid jumped tenfold this year, costing billions of dollars in additional emergency funding as the nation nears the end of a historically calamitous year. More than 4.7 million Americans — or about 1.4 percent of the population — have registered so far this year for disaster aid from the Federal Emergency Management Agency. In 2016, 480,000 sought aid, and fewer than 180,000 people registered for disaster assistance in each of the three previous years. Three hurricanes — Harvey, Irma and Maria — collectively affected an area with about 8 percent of the U.S. population. The hurricanes were followed by wildfires that killed 43 people and destroyed more than 7,000 homes here in wine country..."

The company has produced 6,000 liters of coffee oil for the pilot project with London's transportation authority -- enough to help power the equivalent of one city bus for a year. "It's a great example of what can be done when we start to reimagine waste as an untapped resource," bio-bean founder Arthur Kay said in a statement. The startup collects used coffee grounds from cafes, restaurants and factories, and transports them to its recycling facility. There, the grounds are dried before coffee oil is extracted. The coffee oil is then blended with other fuels to create B20 biofuel, which can be used in diesel buses without modification.

Warren Buffet: The Three Things I Look For In a Person. Farnam Street has a good read: "...You’re looking for three things, generally, in a person,” says Buffett. “Intelligence, energy, and integrity. And if they don’t have the last one, don’t even bother with the first two. I tell them, ‘Everyone here has the intelligence and energy—you wouldn’t be here otherwise. But the integrity is up to you. You weren’t born with it, you can’t learn it in school.” Buffett and Munger were fortunate. They were both smart and worked hard to improve that advantage. The integrity, however, they chose. “You decide to be dishonest, stingy, uncharitable, egotistical, all the things people don’t like in other people,” argues Warren..."

Shadow of the Future. The author of this post at The Gym argues there are two kinds of businesses: "...This theory, if true, would also explain some counterintuitive findings in customer behaviour. It has long baffled people that, if a customer has a problem and a brand resolves it in a satisfactory manner, the customer becomes a more loyal customer than if the fault had not occurred in the first place. Odd, until you realise that solving a problem for a customer at your own expense is a good way of signalling your commitment to a future relationship. The theory of “continuation probability” would also predict that when a business focuses more narrowly on short-term profit maximisation, it will appear less and less trustworthy to its customers. I suspect that, to anyone who has been awake for the last thirty years, this possibility seems all too plausible..."

The Generalized Specialist: How Shakespeare, Da Vinci and Kepler Excelled. I found an article at Farnam Street fascinating: "...Some skills — like the ability to focus, to read critically, or to make rational decisions — are of universal value. Others are a little more specialized but can be used in many different careers. Examples of these skills would be design, project management, and fluency in a foreign language. The distinction between generalization and specialization comes from biology. Species are referred to as either generalists or specialists, as with the hedgehog and the fox. A generalist species can live in a range of environments, utilizing whatever resources are available. Often, these critters eat an omnivorous diet. Raccoons, mice, and cockroaches are generalists. They live all over the world and can eat almost anything. If a city is built in their habitat, then no problem; they can adapt..."


Blind Triplets "See" Through Others' Eyes With Help of a Smartphone. An article at The Washington Post and thestar.com caught my eye: "As Nick Cantos slid on a sleek pair of glasses, a voice spoke out to him through his iPhone...The three of them, aged 18, are triplets from Arlington, Va., who are completely blind. And the glasses they have on are no ordinary spectacles. They are glasses from Aira, a San Diego-based company that has developed smart glasses to help the blind and visually impaired with everyday tasks. The glasses are equipped with a camera, which feeds a video stream to a remote agent who then narrates what they see in real time over the phone for the user. The woman speaking to Nick was Erin Cater, one of Aira’s network of about 100 agents across the United States. From about 2,700 miles away in San Diego, she served as Nick’s eyes, describing for him everything that came within the camera’s field of vision..."

Want to Live Longer? Get a Dog. But we knew that already, right? CNN reports: "The benefits that come with owning a dog are clear-- physical activity, support, companionship -- but owning a dog could literally be saving your life Dog ownership is associated with a reduced risk for cardiovascular disease and death, finds a new Swedish study published Friday in the journal Scientific Reports. For people living alone, owning a dog can decrease their risk of death by 33% and their risk of cardiovascular related death by 36%, when compared to single individuals without a pet, according to the study. Chances of a heart attack were also found to be 11% lower. Multi-person household owners also saw benefits, though to a lesser extent. Risk of death among these dog owners fell by 11% and their chances of cardiovascular death were 15% lower. But their risk of a heart attack was not reduced by owning a dog..."

Climate Stories...

Doomsday on Ice. What do we really know about the rate of Antarctic glaciers in the past, and what it means in today's rapidly warming world? Here's an excerpt of a story from Eric Holthaus at Grist: "...The ocean floor gets deeper toward the center of this part of Antarctica, so each new iceberg that breaks away exposes taller and taller cliffs. Ice gets so heavy that these taller cliffs can’t support their own weight. Once they start to crumble, the destruction would be unstoppable. “Ice is only so strong, so it will collapse if these cliffs reach a certain height,” explains Kristin Poinar, a glaciologist at NASA’s Goddard Space Flight Center. “We need to know how fast it’s going to happen.” In the past few years, scientists have identified marine ice-cliff instability as a feedback loop that could kickstart the disintegration of the entire West Antarctic ice sheet this century — much more quickly than previously thought. Minute-by-minute, huge skyscraper-sized shards of ice cliffs would crumble into the sea, as tall as the Statue of Liberty and as deep underwater as the height of the Empire State Building. The result: a global catastrophe the likes of which we’ve never seen..."

Simple but Powerful Ways to Reduce Carbon Emissions. Here's an excerpt from an article at Press-Citizen: "...Food waste is responsible for 8 percent of all climate emissions.  A third of all food raised or prepared does not make it to our dinner tables. Imperfect-looking fruits and vegetables are rejected by manufacturers and consumers, and are left to rot in huge warehouses or on grocery shelves. Restaurants serve massive portions of food that are often left uneaten by the customer and immediately thrown into the garbage. According to a recent report, the energy that goes into the production, harvesting, transporting and packaging of wasted food generates more than 3.3 billion metric tons of carbon dioxide. If food waste were a country, it would be the world's third-largest emitter of greenhouse gases, behind the U.S. and China..."

Battered by Extreme Weather, Americans Are More Worried About Climate Change. Here's a clip from The Guardian: "...Americans are nevertheless growing increasingly concerned about climate change. A record 22% are very worried about it (double the number in the March 2015 survey), and 63% of Americans are at least somewhat worried about climate change. That’s probably because they perceive direct climate impacts – 64% of survey participants think that global warming is affecting the weather, and 33% said it’s having a big influence. Americans also connecting the dots to specific extreme weather events. About 54% said that climate change worsened the extreme heat waves, wildfires, and hurricanes that pummeled the country in 2017..."

White House Disaster Aid Request Falls Short, Lawmakers Say: From Climate Nexus: "The White House requested Friday an additional $44 billion in disaster aid, in the Trump administration's third bid for additional relief from Congress since this summer's hurricanes. Several lawmakers criticized the package as being too small--Texas alone has requested $61 billion in disaster aid--while calling out proposed cuts to longer-term disaster aid and mitigation programs to help pay for immediate relief. The New York Times reports that one of the proposed cuts in the package would remove $520 million from the Army Corps of Engineers flood control and coastal emergencies program to pay for immediate hurricane relief. Some politicians also highlighted the $1.5 trillion in potential cuts in the separate GOP tax reform bill before Congress as Americans in Puerto Rico, Florida and Texas still struggle to recover."

Added Arctic Data Shows Global Warming Didn't Pause. ScieceDaily has the story: "A University of Alaska Fairbanks professor and his colleagues in China built the first data set of surface temperatures from across the world that significantly improves representation of the Arctic during the "global warming hiatus." Xiangdong Zhang, an atmospheric scientist with UAF's International Arctic Research Center, said he collaborated with colleagues at Tsinghua University in Beijing and Chinese agencies studying Arctic warming to analyze temperature data collected from buoys drifting in the Arctic Ocean. "We recalculated the average global temperatures from 1998-2012 and found that the rate of global warming had continued to rise at 0.112C per decade instead of slowing down to 0.05C per decade as previously thought," said Zhang who is also a professor with UAF's College of Natural Science and Mathematics..."
