Cue the Hallelujah Chorus: Spring Arrives This Weekend. Finally

The Rumors are True: Spring Fling is Imminent

Cue Handel's "Hallelujah Chorus". It's time to break out confetti and (cheap) champagne, because after multiple false-starts spring is finally paying a visit to Minnesota.

If you doubt that we live in the Super Bowl of Weather consider this: a blizzard last weekend - 60s this weekend. Mother Nature needs to be sedated.

In Atlanta, Dallas and Little Rock spring is a given; locals tend to take it for granted. Not here. The Midwestern Regional Climate Center counted 130 snowfall records across the Midwest in April. 26.1 inches in the Twin Cities - but 47.1 inches in Kalkaska, Michigan.In April.

Dry weather may spill over into most of next week as a warming ridge of high pressure builds over the central USA; storms sliding south of home until further notice. An August-like sun angle will remove most of the snow in your yard by Sunday, and then the mercury can reach into the 60s. I wouldn't be surprised to see 70 degrees by the end of next week. Be still my heart.

I am really looking forward to strangers waving at me with all their fingers again. Bring on the warmth! 


Yes. ECMWF guidance hints at a pretty good shot at 60 degrees Sunday and Monday; another surge of warmth later next week. I suspect/hope we're really turning the corner - finally. Source: WeatherBell.






Drought Returns to Huge Swaths of U.S. - Fueling Fears of a Thirsty Future. Here's an excerpt from The Los Angeles Times: "Texas Less than eight months after Hurricane Harvey pelted the Texas Gulf Coast with torrential rainfall, drought has returned to Texas and other parts of the West, Southwest and Southeast, rekindling old worries for residents who dealt with earlier waves of dry spells and once again forcing state governments to reckon with how to keep the water flowing. Nearly a third of the continental United States was in drought as of April 10, more than three times the coverage of a year ago. And the specter of a drought-ridden summer has focused renewed urgency on state and local conservation efforts, some of which would fundamentally alter Americans' behavior in how they use water..."

Wildfires: From Climate Nexus: "A massive wildfire is spiraling out of control in Oklahoma (Earther, Reuters), Southwest fire threat called ‘extreme to historic’ amid brutally hot and dry conditions (Washington Post $), Climate change, wildfire, and the future of forests." (Outside Magazine)


Decoding the Weather Machine. If you missed the program Wednesday evening you can stream the 2-hour PBS NOVA special here: "Disastrous hurricanes. Widespread droughts and wildfires. Withering heat. Extreme rainfall. It is hard not to conclude that something’s up with the weather, and many scientists agree. It’s the result of the weather machine itself—our climate—changing, becoming hotter and more erratic. In this two-hour documentary, NOVA will cut through the confusion around climate change. Why do scientists overwhelmingly agree that our climate is changing, and that human activity is causing it? How and when will it affect us through the weather we experience? And what will it take to bend the trajectory of planetary warming toward more benign outcomes? Join scientists around the world on a quest to better understand the workings of the weather and climate machine we call Earth, and discover how we can be resilient—even thrive—in the face of enormous change."


This Towering "Snow Canyon" is Carved Into One of the Snowiest Places on Earth. I felt a little better about nearly 80" of snow this winter in the Twin Cities after reading this post at Capital Weather Gang: "There’s a mountain in Japan where the snow falls so heavily they don’t even attempt to clear it until spring. As much as 125 feet of snow falls on this mountain each year — around 1,500 inches. It is the snowiest place in Japan, and probably one of the snowiest places on Earth. Tateyama (Mount Tate) is one of Japan’s three holy mountains, located on the west side of the country near the Sea of Japan. It’s a popular destination for hikers in the warm months, and just as popular in late winter after workers carve canyon of snow onto the mountain peak..."

The Federal Emergency Management Agency (FEMA) is still dealing with last year’s hurricane season—and the 2018 season is less than two months away. The federal agency extended its shelter program another month for survivors of Hurricane Harvey Tuesday, while the Puerto Rican government requested that FEMA extend the Transitional Assistance Program for Hurricane Maria refugees Wednesday. Both these programs help cover the costs of hotels and other temporary housing for individuals and families whose homes were left uninhabitable after these destructive natural disasters..."

It's a Common Myth That Tornadoes Avoid Cities - But It's Not True. Meteorologist Marshall Shepherd makes the case at Forbes: "...About a decade ago, Dr. Josh Wurman and colleagues published a paper in the Bulletin of the American Meteorological Society called "Low-Level Winds in Tornadoes and Potential Catastrophic Tornado Impacts in Urban Areas." They used wind estimates from Doppler on Wheels mobile radars, census data, and modeling to estimate impacts of tornadoes crossing densely populated cities. Results were startling. For example, they argued that a large, intense tornado moving through parts of Chicago, Illinois could destroy nearly a quarter of a million homes and result in 4500 to 45,000 deaths. They did similar evaluations for Atlanta, Washington, D.C., Houston, Dallas-Ft. Worth, New York, and St. Louis. While this results may be exaggerated as noted by some scholars in the literature, I think the point that they convey is real..."

San Francisco's Big Seismic Gamble. The New York Times reports: "San Francisco lives with the certainty that the Big One will come. But the city is also putting up taller and taller buildings clustered closer and closer together because of the state's severe housing shortage.  Now those competing pressures have prompted an anxious rethinking of building regulations. Experts are sending this message: The building code coes not protect cities from earthquakes nearly as much as you might think. It's been over a century - Wednesday marks the 112th anniversary - since the last devastating earthquake and subsequent inferno razed San Francisco...."


More Than 95% of the World's Population Breathes Dangerous Air. The Guardian reports: "More than 95% of the world’s population breathe unsafe air and the burden is falling hardest on the poorest communities, with the gap between the most polluted and least polluted countries rising rapidly, a comprehensive study of global air pollution has found. Cities are home to an increasing majority of the world’s people, exposing billions to unsafe air, particularly in developing countries, but in rural areas the risk of indoor air pollution is often caused by burning solid fuels. One in three people worldwide faces the double whammy of unsafe air both indoors and out. The report by the Health Effects Institute used new findings such as satellite data and better monitoring to estimate the numbers of people exposed to air polluted above the levels deemed safe by the World Health Organisation. This exposure has made air pollution the fourth highest cause of death globally, after high blood pressure, diet and smoking, and the greatest environmental health risk..."

U.S. Wind Energy Now Supplies More Than 30% in Four States. Clean Technica has the story; here's a clip: "Wind energy is one of the fastest growing forms of electricity generation in the United States, with the largest share renewable electricity generating capacity in the country, and according to new information from the American Wind Energy Association, wind energy now supplies more than 30% of the electricity in four states — Iowa, Kansas, Oklahoma, and South Dakota...According to this latest report, wind power generated 6.3% of US electricity in 2017. However, wind’s impact can be better seen in its role in states like Iowa, Kansas, Oklahoma, and South Dakota, where it is generating over 30% of capacity..."



Scientists Inadvertently Create Mutant Plastic-Eating Enzyme. The Daily Beast explains: "An international group of scientists has accidentally created an enzyme that eats plastic, a discovery that is being hailed as a major breakthrough in the fight against pollution. The mutant enzyme stems from the 2016 discovery of a bacterium that had evolved to devour plastic at a waste site in Japan. Scientists from Britain’s University of Portsmouth and the U.S. Department of Energy’s National Renewable Energy Laboratory then altered that enzyme to study its evolution, but they later learned they had actually improved its ability to break down plastic. “Serendipity often plays a significant role in fundamental scientific research and our discovery here is no exception,” Portsmouth biologist John McGeehan said of the finding. Researchers say the enzyme can be further enhanced and used as a new recycling solution. An estimated 8 million metric tons of plastic waste winds up in the world’s oceans each year, wreaking havoc on the ecosystem..."

More People Have Amazon Prime Than Live in Germany. Quartz reports: "Amazon Prime now has more than 100 million members, CEO Jeff Bezos said April 18 in his annual letter to shareholders. For context, that’s greater than the population of Germany, Vietnam, or Egypt. From the shareholder letter: "13 years post-launch, we have exceeded 100 million paid Prime members globally. In 2017 Amazon shipped more than five billion items with Prime worldwide, and more new members joined Prime than in any previous year – both worldwide and in the U.S. Members in the U.S. now receive unlimited free two-day shipping on over 100 million different items. We expanded Prime to Mexico, Singapore, the Netherlands, and Luxembourg, and introduced Business Prime Shipping in the U.S. and Germany..."

Georgia Teen Makes Her Prom Entrance in a Casket. Yes, she got her point across, according to a story at Yahoo: "...As Clark explained to USA Today, she currently works at a funeral home and plans to be a funeral director once she graduates from Ogeechee Technical College. She chose her unusual ride in part to celebrate her career choice, and in part to warn her fellow classmates against drinking and driving. “I was thinking about my class and how they are going to prom and doing the bad stuff after prom; like having drugs and doing all that,” she said. In light of the current debate over guns in schools, this stunt has angered some people who say a teen in a casket is all too reminiscent of real life..."


Forecast Calls for Severe Tumbleweeds. I've never seen this before; a post at NPR.com explains: "A strong breeze can toss around all sorts of detritus, but for residents of one California community on the edge of the Mojave Desert, where area gusts topped 50 mph Monday, it was tumbleweeds at the whims of the wind. Lots of tumbleweeds. "It looked like a war of tumbleweeds, like we were being invaded," Victorville resident Bryan Bagwell, 42, tells NPR. He says cleanup in Victorville, about an 85-mile drive from Los Angeles, was continuing Wednesday. Dozens of homes in his neighborhood, which borders an undeveloped tract of desert land, were seemingly swallowed up by mounds of the dry brush. Bagwell says the buildup reached 7 feet high on his own property and that it took a laborer several hours with a pitchfork to move the tumbleweeds to the street for the city to pick up with a front loader..."

What Snow? Small Minnesota High School Team Clears Entire Baseball Field. Now that's the spirit! Bring Me The News Explains: "If last weekend's blizzard was a curve ball, the Atwater-Cosmos-Grove City Falcons knocked it out of the park. ACGC, a small high school located about 90 miles west of Minneapolis, spent Monday's snow day clearing their baseball field in Atwater.  No exaggeration, their baseball players and coaches, in addition to other volunteers, literally removed 10 inches of snow from the field, not to mention larger drifts created by the blizzard's fierce winds.  It went from looking looking like a blinding white blanket of heavy, wet snow to what you see in the photo above...Kingery then got the shoveling party started by texting all of the school's baseball players, inviting anyone interested to come help clear the field. More than 30 people responded with shovels and snowblowers, and they wound up clearing the entire field, a seven-hour task that Kingery described as "daunting..."

Climate Stories....

Americans Who Accept Climate Change Outnumber Those Who Don't by 5 to 1. Yale E360 has the story: "Seventy percent of Americans now accept that climate change is happening, outnumbering those who don’t by a 5 to 1 ratio, according to a new survey by the Yale Program on Climate Change Communication. More than half of those surveyed, 58 percent, said they also understand global warming is caused mostly by human activities, such as the burning of fossil fuels. The share of Americans who think climate change is happening has increased seven percentage points since March 2015. Their certainty has increased 12 percentage points in three years, with 49 percent of the U.S. now “extremely” or “very sure” it is happening, according to the new survey..."



Sea Levels Could be Rising Faster Than Predicted Due to New Source of Antarctic Ice Melting. The Independent has the story; here's a clip: "...The research was published in the journal Science Advances. It comes shortly after analysis by a team at the University of Leeds found an area of underwater ice the size of Greater London had melted from the bottom of the region’s ice shelves in just five years. Ice shelves currently act as structural support, holding the Antarctic ice sheet in place. Warm waters flowing underneath these shelves will diminish this support as they cause them to decline and fragment. Other studies have demonstrated that the “catastrophic collapse” of areas like the West Antarctic ice sheet have the capacity to raise global sea levels by more than three metres..."

Glacier Loss is Accelerating Because of Global Warming. University of St. Thomas scientist John Abraham reports for The Guardian: "... A paper was just published by the American Geophysical Union that shared research carried out by Dominic Winski and his colleagues. This team of researchers extracted ice cores from the glaciers on Mt. Hunter, in Alaska. The ice cores held snow and ice from as far back as 400 years. The researchers showed that the amount of water melt currently is 60 times greater than it was prior to 1850. They also found that the summertime temperature changes on Mt. Hunter are almost 2°C per century (about 3.5°F). To put this in perspective, the temperatures are rising about twice as fast as global temperatures. The fact that temperatures on these northern mountains is rising faster than the globe as a whole is something predicted by climate models..."

Pruitt Upgraded to a Larger, Customized SUV with Bullet-Resistant Seat Covers. Here's an excerpt from The Washington Post: "Environmental Protection Agency Administrator Scott Pruitt upgraded his official car last year to a costlier, larger vehicle with bullet-resistant covers over bucket seats, according to federal records and interviews with current and former agency officials. Recent EPA administrators had traveled in a Chevrolet Tahoe, and agency officials had arranged for Pruitt to use the same vehicle when he joined the administration in February last year. But he switched to a larger, newer and more high-end Chevy Suburban in June. One former EPA official, who spoke on the condition of anonymity out of fear of retaliation, said Pruitt remarked that he wanted the larger car because it was similar to ones in which some other Cabinet officials rode. The first year’s lease of the vehicle cost $10,200, according to federal contracting records..."

Great Barrier Reef Feels the Heat: Headlines and links via Climate Nexus: "The Great Barrier Reef will never be the same after an unprecedented heat wave in 2016, according to a new study in Nature. Nearly 30 percent of the reef’s corals perished during the nine-month heat wave, which disproportionately affected different species. Because of the extent of the losses, the researchers believe that it’s likely the “entire ecological identity” of the reef system has changed. Terry Hughes, one of the lead scientists of the study, said that if global warming continues at its current pace, “it’s game over” for the reef."

Here's What Happens When You Tell People the Scientific Consensus on Climate Change. Here's a clip from a post at ThinkProgress: "...The overwhelming majority of climate scientists — 97 percent  — understand that humans are the primary cause of climate change. Yet, as a new peer-reviewed study in journal Nature Climate Change points out, “only 11 percent of the US public correctly estimate the scientific consensus on climate change as higher than 90 percent.” So what happens when you inform people about the actual consensus on climate science? Researchers in the Nature study did a survey experiment with 6,300 Americans and found exposing the survey respondents to the message about the scientific consensus increases their perception of the scientific norm by 16.2 percentage points on a 100-point scale..."

How do Climate Models Work? Carbon Brief has a good explainer; here's an excerpt: "...A global climate model typically contains enough computer code to fill 18,000 pages of printed text; it will have taken hundreds of scientists many years to build and improve; and it can require a supercomputer the size of a tennis court to run. The models themselves come in different forms – from those that just cover one particular region of the world or part of the climate system, to those that simulate the atmosphere, oceans, ice and land for the whole planet. The output from these models drives forward climate science, helping scientists understand how human activity is affecting the Earth’s climate. These advances have underpinned climate policy decisions on national and international scales for the past five decades..."

Agonizingly Late - But Spring is Coming: 50s and 60s by Next Week

Growing Risk of a "Light-Switch" Spring?

Some years we ease into spring; waves of increasingly warm air lapping northward. Other years we go from a shoe-full-of-slush to 60s in a blink of an eye. Jackets and shorts, in the same week. This will probably be one of those years.

According to NOAA data the average date of the first 60-degree high in the Twin Cities is March 23. Right. The latest we've ever gone before savoring 60 degrees? April 29, 1874.

The more snow we melt, the faster the sun can start to heat up the air. Although a few stubborn piles of snow will hang around the next 1-2 weeks, much of the snow will be gone by Sunday, when temperatures may brush 60F in the Twin Cities. Birds will chirp, pessimists will exhale, dark moods may finally lift a bit - after the toughest winter in 4 years. Expect a string of dry days until next Tuesday, when rain showers may pop up.

Dan Luna at the National Weather Service sees a perfectly orderly snow melt. There's 1-2 inches of liquid water trapped in the snow. Unless we experience a parade of rain storms the next few weeks - we should avoid a worst-case flood scenario. 


Snowfall Reports. Up to a foot of snow fell over far southern Minnesota Wednesday; just flurries in the Twin Cities. Click here for the latest snowfall updates from NOAA.



A Consistent Signal. Spring has had many false starts this (alleged) spring, so I don't blame you for being skeptical. So am I, on some level. But NOAA, Canadian and ECMWF models are (consistently) showing 50s and 60s next week as we finally, almost grudgingly, make the turn toward spring. Twin Cities numbers: WeatherBell.

Mild Start to May. If this forecast for 500mb (18,000 foot) winds from NOAA's GFS model verifies it spells a relatively warm start to May, with chilly, stormy weather for California and much of the western USA.



River Flood Potential Update. I had an e-mail conversation with Dan Luna, Meteorologist in Charge of the Twin Cities National Weather Service. I asked him to weigh in on the risk of flooding, in light of last weekend's historic snowfall and the fact that there's still over a foot of frost in the ground. Here is what he told me (updated): "We received a couple of isolated SWE reports of 2.0 inches in SW MN, with an isolated 2.8 inches near redwood Falls. We see about 1.5' to slightly more than 2 inches of water contained in the snow pack across much of the area. This week into the weekend features a perfect orderly snow melt. It could not be better in terms of temperatures in the upper 30's to low 40's through Thursday with lows below freezing at night. Friday through Sunday see temperatures warming to the low 50's with lows dropping to around the freezing mark; perfect! No significant rain, that could cause the snow to liquidate overnight is in the forecast through the weekend which add to the "perfectness" of snow melting. In addition due points will be relatively low; not causing snow to melt rapidly. By Monday of next week, most of the runoff from snow melt will be well on it's way down the creeks and river systems. Snow that is forecast to fall over southern MN Tuesday night through Wednesday is not expected to provide much more to the potential of flooding in our state. It is amazing at this point in time that only one point on the MN River is expected to reach minor flooding; Montevideo. Much of this is due to the fact that we have been melting snow periodically the last 6 weeks. March was a dry month and April is running about an inch above normal. So at this point we are not very far out of bounds as to what we would expect in liquid precipitations. It is just the snow amounts are way out of bounds as evidenced by a new April record. We will have to pay close attention this month and into May; if we had widespread significant rains, we could expect widespread significant flooding, but that is not expected at this time...I actually think the bigger threat for flooding could come in May/June (after the snow melts). Rivers will be plenty high, soils wet, vegetation behind in terms of greenness and taking water out of the soils,  and if we get a significant convective system that produces widespread significant rains or a slow moving low pressure system, watch out."

Thunder Blizzard: April 13-16. The Minnesota DNR has a very good summary of last weekend's meteorological craziness; here's an excerpt: "An extreme, late-season winter storm struck Minnesota from April 13-16, 2018, producing everything from thunderstorm wind damage to prolonged blizzard and whiteout conditions.The storm came in three distinct rounds, each separated by anywhere between four and eight hours. The first round began on the morning of Friday April 13th, as severe thunderstorms tore into far southwestern Minnesota from South Dakota, knocking over power poles, damaging farm equipment, and producing a wind gust of 78 mph near Rushmore in Nobles County. Precipitation accompanied by 45 mph wind gusts then spread across the southern half of the state, with a mix of rain, sleet, freezing rain, and eventually snow, resulting in 1-4 inches of accumulation from the Twin Cities northward, and up to 8 inches near the Minnesota River in western Minnesota, before ending just after midnight..."



When Spring's Snow Typically Happens. Read it and weep. Here's an excerpt from weather.com: "By spring, the sight of a blanket of snow may cause more aggravation among the snow-fatigued instead of the excitement it generated in October or November. We scoured National Weather Service records to compile both the average date of the final measurable (at least 0.1 inches) snow of the spring, and also the date of the latest spring accumulating snow on record. In some locations, that record latest date was in the summer..."

How Large Outdoor Venues Prepare for Severe Weather. It's something that haunts me - how do you move 30,000 to 40,000 people in a few minutes if a confirmed tornado is approaching a stadium? Here's an excerpt from KSHB.com: "...The stadium is made of concrete and the main level and field are both underground. In the case of a tornado, fans in the upper decks would be brought to the main level and fans on the main level would be escorted down to underground tunnels. "If we have a full stadium and a weather event is bearing down on us, we could get all 40,000 people into a safer location within 15 minutes,” said Cook. But until fans are inside the stadium, their safety isn’t guaranteed..."


How Does One Prepare for Adverse Weather Events? Depends on your Past Experience. Science Daily has an intriguing post: "...The results indicate that people's risk perceptions are highly influenced by a memorable past tornado experience that contributes to unwelcome thoughts, feelings and disruption, which ultimately increase one's fear, dread, worry and depression. Also, the more experiences people have with tornadoes, and the more personalized those experiences, the more likely they are to believe their homes (versus the larger geographic area of their city/town) will be damaged by a tornado within the next 10 years..."


The National Weather Service Forecast: More Budget and Staff Cuts. Here's a clip from Chicago Magazine: "...Nationwide, NWS staffers are struggling to keep up as jobs go unfilled for long periods due to attrition, according to a GOA report that says ongoing staff vacancies make it difficult for those remaining to “complete key tasks.” This is cause for concern given the frequency and intensity of weather-related disasters, including 16 separate events that each left more $1 billion in damages in 2017. “And those numbers don’t account for the human toll,” says Izzi. Weather and climate disasters killed 362 people last year, according to the National Oceanic and Atmospheric Administration. Some say the toll is much higher. A few months after Hurricane Maria hit, the New York Times reported that a more “reliable measure of the disaster’s human impact” was 472 deaths just in Puerto Rico alone..."

Harsher Winters and Rising Seas: Study Finds Slowing Ocean Could Mean Climate Extremes. NBC News highlights new research into an apparent slowing of the Atlantic's Gulf Stream conveyor belt: "...A major system of currents in the Atlantic Ocean that carries millions of cubic meters of water north each day is slowing down, according to a new peer-reviewed study published in the journal Nature. That system is known as the Atlantic Meridional Overturning Circulation, or AMOC. "We know somewhere out there is a tipping point where this current system is likely to break down," said study co-author Stefan Rahmstorf, a climate scientist at the Potsdam Institute for Climate Impact Research in Germany. "We still don't know how far away or close to this tipping point we might be. ... This is uncharted territory..."

Paul Douglas Talks Climate Change Ahead of NOVA Special. I've seen an advance screener of the 2-hour documentary, and KARE-11 footage makes the final cut in Wednesday's 7-9 PM NOVA film. Here's an excerpt from KARE-11: "...I think its funny, we are wired to experience weather, none of us are wired to experience climate. You don't look out the window and see climate. But if you get clubbed over the head repeatedly and experience jaw-dropping historic weather events, it stops being a fluke, an aberration and it starts becoming a trend." "At first I thought I was imagining, I thought maybe it was my meds, maybe I was hallucinating. And I reached out to other meteorologists and they were seeing the same things. Some of them not excited to be talking about it on the air," Douglas continued. "As you know, if you try to connect the dots and you whisper climate change, you are going to alienate maybe 30 percent of the audience who think it's a scam, a hoax, a liberal conspiracy. No. No. No." "There's more water in the air, you warm up the air two degrees, that's 8 percent more water vapor, that's jet fuel for these storms which drives these intense summer rains..."


Puerto Rico's Power Outage is Now the Second-Largest Blackout in History. Hurricane Maria's legacy lives on - here's an excerpt from CNN: "Since the monster storm slammed into the American Caribbean territory in September 2017 and heavily damaged the power grid, more than 3.4 billion hours of electricity have been lost there. That makes it the second-longest blackout in world history, according to a report from the Rhodium Group, an economic research firm. The only blackout in world history bigger than Puerto Rico's is the one that came after Typhoon Haiyan devastated the Philippines in 2013. About 6.1 billion hours of power were lost after that massive storm..."

The Daily Beast explains: "An international group of scientists has accidentally created an enzyme that eats plastic, a discovery that is being hailed as a major breakthrough in the fight against pollution. The mutant enzyme stems from the 2016 discovery of a bacterium that had evolved to devour plastic at a waste site in Japan. Scientists from Britain’s University of Portsmouth and the U.S. Department of Energy’s National Renewable Energy Laboratory then altered that enzyme to study its evolution, but they later learned they had actually improved its ability to break down plastic. “Serendipity often plays a significant role in fundamental scientific research and our discovery here is no exception,” Portsmouth biologist John McGeehan said of the finding. Researchers say the enzyme can be further enhanced and used as a new recycling solution. An estimated 8 million metric tons of plastic waste winds up in the world’s oceans each year, wreaking havoc on the ecosystem..."

When Will We Separate Women on TV From Their Bodies? An Op-Ed at ESPN.com caught my eye; here's an excerpt: "...This might sound naive to many, but I didn't understand just how commonly and flagrantly women are objectified or reduced to a body until I became a public figure on social media. Of course, men make comments to me in person, but the sheer volume of references to body parts or sex acts, lewd photos or comments I get on social media -- no matter the context, what I'm wearing, saying or doing -- has changed how I look at things. I now walk through the world understanding that no matter how I present myself and no matter my intentions or actions, I can't always control how I'm seen. I don't speak for all women, but for some of us, it can be a very uncomfortable feeling to be sexualized when you're not seeking out that kind of attention or intending in any way to project sexuality..."


Too Hot for the Beaches: Turkmenistan Bans Imports of Bikinis. You can't make this stuff up. Here's an excerpt from Radio Free Europe: "...The Turkmen government has banned the import of new bikinis and other traditional swimwear, forcing swimmers and other beachgoers to use their old suits or come up with their own fashions. Owners of swimwear shops say customs officials have also in recent months halted the import of any swimsuits, as well as short pants for both men and women...it's unclear what people without a bathing suit will wear in the arid Central Asia nation -- and for those who like wearing shorts in a country where summer temperatures can reach 50 degrees Celsius. It’s also unclear whether old bikinis will also fall afoul of government fashion norms. New bikinis and shorts are just the latest in a long line of goods that the Turkmen government has decided aren’t acceptable for its people..."

Climate Stories....

Here's What Happens When You Tell People the Scientific Consensus on Climate Change. Here's a clip from a post at ThinkProgress: "...The overwhelming majority of climate scientists — 97 percent  — understand that humans are the primary cause of climate change. Yet, as a new peer-reviewed study in journal Nature Climate Change points out, “only 11 percent of the US public correctly estimate the scientific consensus on climate change as higher than 90 percent.” So what happens when you inform people about the actual consensus on climate science? Researchers in the Nature study did a survey experiment with 6,300 Americans and found exposing the survey respondents to the message about the scientific consensus increases their perception of the scientific norm by 16.2 percentage points on a 100-point scale..."

How do Climate Models Work? Carbon Brief has a good explainer; here's an excerpt: "...A global climate model typically contains enough computer code to fill 18,000 pages of printed text; it will have taken hundreds of scientists many years to build and improve; and it can require a supercomputer the size of a tennis court to run. The models themselves come in different forms – from those that just cover one particular region of the world or part of the climate system, to those that simulate the atmosphere, oceans, ice and land for the whole planet. The output from these models drives forward climate science, helping scientists understand how human activity is affecting the Earth’s climate. These advances have underpinned climate policy decisions on national and international scales for the past five decades..."


Warming Climate to Nearly Double Demand for Cooling Appliances. Which increases the need for more energy, much of which will depend on the burning of fossil fuels. Which amplifies warming. The Guardian explains: "A burgeoning middle class and a warming world will result in energy demand for cooling overtaking that for heating by the middle of the century, researchers have predicted. Energy use for air conditioning, refrigeration and other cooling appliances will jump 90% on 2017 levels, experts estimated, posing a challenge for energy grids and efforts to curb climate change. The University of Birmingham said the rise would come even with conservative estimates of how much demand for cooling was likely to increase in China, India and hotter countries. “Cooling just really isn’t part of the big debate. And yet we lose 200m tonnes of food each year because of a lack of cooling. That has massive repercussions,” said Toby Peters, professor in cold economy at the university..."

How the Science of Persuasion Could Change the Politics of Climate Change. Conservatives making the (economic) case to other conservatives? Imagine that. Here's a clip from MIT Technology Review: "...Now he’s president of the Niskanen Center, a libertarian-leaning Washington, DC, think tank he founded in 2014. He and his colleagues there are trying to build support for the passage of an aggressive federal carbon tax, through discussions with Washington insiders, with a particular focus on Republican legislators and their staff. A small but growing contingent of fiscal conservatives and corporate interests are arguing for similar policies in the United States. They include party elders like former secretary of state George Shultz, energy giants like Exxon Mobil, and nearly two dozen college Republican groups. Taylor and others believe it’s conversations like these—with political elites, and focused on policies they can justify in conservative terms—that could eventually lead to real action on climate change..."

New York City's Real Estate Industry Must Lead Way on Climate - And It Is. An Op-Ed at Crain's New York explains: "...Clearly, the real estate community must be at the forefront of the solution. The good news is, we already are. Building owners and managers recognize what must be done and we see it taking place. New boilers are more precise at calibrating heating levels and conserving energy; HVAC systems are cleaner and more efficient; better insulation and windows are more effective at reducing waste; innovations such as green roofs are regulating temperatures naturally. The switch by many buildings to natural gas, which burns cleaner and with less pollution than oil, has only accelerated. According to the Department of Environmental Conservation, natural-gas use in city buildings increased 25% from 2005 to 2015..."

Shell Joins Exxon in the Climate Change Spotlight. Here's an excerpt from The Houston Chronicle: "Royal Dutch Shell, one the world’s biggest oil companies, recognized that burning fossil fuels was raising global temperatures as early as the 1980s, but continued to produce and sell oil, gas and petroleum products, according to documents obtained and released by a European news site.Shell, which has its North American headquarters in Houston and employs about 12,000 here, joins Exxon Mobil as a target of intensifying questions about what oil companies knew about the role of fossil fuels in climate change and when they knew it. Exxon, headquartered in Irving, has received the brunt of the scrutiny in recent years, also facing accusations — which the company denies — that it knew about the climate repercussions of its business in the 1980s, but hid the evidence..."
