Wild Weather Week - Near Record Warmth on Friday?

"Hey Paul, I can't keep up with this! 60's one day and humid 90's a week later?" a friend, David Levin, lamented. I'm with you Dave - I'm just as confused as everyone else. Which reminds me of my favorite weather proverb: "There's no such thing as bad weather, just poor clothing choices." Right.
On Monday Minnesotans were wandering the streets in jackets, with "highs" in the 50s. Friday, the first day of autumn, highs may surge into the low to mid 90s - nearly 25F warmer than average. Let's have a moment of silence for "average".
This push of August-like air sets off a thundershower by tonight, but the sun should be out much of Friday as we break out into the hot side of the front. A lazy cool front sputters and stalls over Minnesota this weekend; the best chance of showers and T-storms over central and western counties, where several inches of rain may fall. Puddles linger into Tuesday, before a push of Canadian air dries us out the latter half of next week.
Dig out shorts for Friday, but jackets return next week. Welcome to the meteorologically-manic month of September.

Severe Reports Tuesday Night. The squall line weakened by the time it reached the Twin Cities, but there were numerous reports of large hail and damaging straight-line winds over north and west of St. Cloud. More details via NOAA.

70-Degree Nighttime Lows in Late September. We may set a few records for warmest nighttime lows, according to the Minnesota State Climatology Office: "According to the current NWS forecast, the Twin Cities could experience its latest-on-record run of two or more consecutive days with low temperatures at or above 70 F. In fact, the forecast calls for the record to be broken by nearly a week!"

Summery Weekend. Last stretch of 80s before the flakes fly? I doubt it - we'll see more 70s and probably a few 80s during the first half of October, but after a warm, sticky weekend temperatures do cool down to jacket-levels next week. Twin Cities ECMWF forecast: WeatherBell.

Another Super-Soggy Holding Pattern. You can see Jose and Maria's projected path (just off the East Coast - a bit close for comfort) and a secondary stripe of excessive rain from Texas to Minnesota, where some 4-5" rainfall amounts are possible as a frontal boundary limps east.

Praedictix Briefing: Issued Wednesday, September 20th, 2017:

*Maria made landfall earlier this morning around 6:15 AM AST near Yabucoa, Puerto Rico, as a dangerous Category 4 hurricane with 155 mph winds. Recently, a wind gust of 113 mph was reported in San Juan, with a 118 mph wind gust at Camp Santiago.

*Flash Flood Emergencies are in effect along the Rio La Plata and Rio Grande de Loiza due to dangerous runoff associated with Maria that is expected to cause significant flooding in communities along these rivers.

*The eye of Maria is currently sitting over eastern Puerto Rico with 145 mph winds as of 9 AM AST. Maria will continue to move over the island today and likely weaken some. However, the system will continue to produce heavy rain, flash flooding, destructive winds and life-threatening storm surge.

*Maria will continue off to the northwest over the next couple days, before moving more northward into the weekend. Some weakening is expected during this period due to slightly unfavorable atmospheric conditions. Models continue to keep Maria away from the Southeastern U.S. coast into next week.

*We also continue to track Jose, still sitting off the Northeast coast as of this morning as a tropical storm. While Jose will continue to weaken over the next couple days, gusty winds along parts of the New England coast, as well as dangerous surf and rip currents can be expected.

Maria Over Puerto Rico. Maria made landfall earlier this morning near Yabucoa, Puerto Rico, as a dangerous Category 4 hurricane with 155 mph winds, making Maria the first Category 4 landfall on Puerto Rico since 1932. Winds have been gusting over 130 mph as Maria made its approach, including a 137 mph gust in Isla Culebrita. Many weather observations sites are no longer reporting conditions, so gusts could potentially still be higher in spots. Flash flooding is also a major concern this morning, with dangerous runoff from heavy rain reported across eastern and northern parts of Puerto Rico. There are Flash Flood Emergencies in effect along the Rio La Plata and Rio Grande de Loiza. As of 9 AM AST, the center of Maria was located 15 miles west-southwest of San Juan. (Satellite data: AerisWeather).

Maria Official Track. Maria will continue to move across Puerto Rico today, emerging into the Atlantic later in the day. The system will move just north of the Dominican Republic through Thursday and into the southeastern Bahamas by Friday. We expect to see some weakening in Maria over the next few days due to a couple factors. First, interaction with land – especially in the next 24-48 hours as the system passes over Puerto Rico and near the Dominican Republic – is expected to help weaken the system. As we head toward the weekend, upper level winds will become less favorable, helping to weaken Maria more. Maria will continue to be a powerful system, with sustained winds of at least 110 mph in the forecast through Sunday morning.

Storm Surge Occurring This Morning. Tide locations in parts of eastern and southern Puerto Rico have already reported a storm surge of 1-3 feet this morning as Maria made landfall. The highest storm surge reported by these tide locations so far has been in Yabucoa Harbor, where a 5.4 foot storm surge was recorded.

Forecast Storm Surge. The threat of storm surge in Puerto Rico and the Virgin Islands will continue today, with a forecast of 6-9 feet possible if it coincides with high tide. Maria is expected to produce life-threatening storm surge later this week along Hispaniola and in the Bahamas and Turks and Caicos as well. Here is what is expected according to the National Hurricane Center:

A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 4 to 6 feet above normal tide levels in the hurricane warning area in the Dominican Republic, and 1 to 3 ft elsewhere along the northern coasts of the Dominican Republic and Haiti.

A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 10 to 15 feet above normal tide levels in the hurricane warning area near and to the north of the center of Maria for both the Southeastern Bahamas and the Turks and Caicos Islands.

Maria Early Next Week. Both the European ECMWF (left) and American GFS (right) continue to show that Maria should stay well offshore of the Southeastern United States as we head into early next week.

Maria Closer To The Northeast U.S. Mid-Next Week? We could see a similar situation to what we are seeing right now with Jose by the middle of next week, as both the European ECMWF (left) and American GFS (right) have the potential of Maria sitting offshore. Confidence levels a week out are low, as Maria could still have interaction with what is left of Jose and push further out into the Atlantic. We will continue to track the latest on Maria to see if this system will bring any impacts next week on facilities. Maps: WSI.

Jose Still Alive Off The Northeast Coast. Jose continues to sit offshore the east coast this morning, but as a weaker system than at this time yesterday. As of 8 AM ET, Jose is a Tropical Storm with 65 mph winds, sitting 165 miles south of Nantucket, MA. (Satellite data: AerisWeather)

Jose Official Track. We still see a weakening trend over the next couple days with Jose, and the system is expected to become post-tropical Thursday. The system will move to the east and northeast over the next couple days before high pressure moves in, causing the system to move back to the west and meander in the northwest Atlantic waters into the weekend. We will continue to watch high surf and rip currents along parts of the Northeast coast over the next several days with Jose, with some minor coastal flooding possible as well. Tropical Storm Warnings are still in effect across parts of the New England coast due to the potential of tropical storm force winds as the wind field extends outward 230 miles from the center of the storm. Here is where those warnings are in effect:

A Tropical Storm Warning is in effect for...
* Woods Hole to Sagamore Beach, including Cape Cod

* Block Island
* Martha's Vineyard
* Nantucket

Summary: Maria is moving over Puerto Rico this morning after making landfall with 155 mph winds earlier today. Numerous wind gusts of over 100 mph have been reported on the island. Flash Flood Emergencies are also in effect along the Rio La Plata and Rio Grande de Loiza due to dangerous runoff. Dangerous conditions will continue today across Puerto Rico as Maria continues to move across the island, with the eye expected to exit into the Atlantic later today or tonight. Maria will then track just north of the Dominican Republic into Thursday and close to the southeastern Bahamas by Friday. Heavy rain, dangerous winds and life-threatening storm surge can be expected in these areas through the end of the week. Models continue to indicate that Maria should pass well offshore the Southeast United States into early next week, but could still have some impacts of parts of the east U.S. coast. Jose continues to sit well offshore the Northeast this morning, with the storm slowly weakening. Jose is expected to meander in the Atlantic waters into next week.

The Scariest Thing About 2017's Hurricanes: They Keep Getting Really Strong, Really Fast. Chris Mooney takes a look at rapid intensification in the Atlantic Ocean at The Washington Post: "...It’s not a common event. Typically, that occurs in maybe 5 percent of our forecasts,” said Mark DeMaria, acting deputy director of the National Hurricane Center. But DeMaria said that this season is seeing more rapid intensification events than usual and that Maria, in particular, appears to have set a key record for hurricane rapid intensification in the Atlantic. “Looking back through the records, Maria went from a tropical depression to a Category 5 hurricane in just two and a half days,” he said. “I couldn’t find any other tropical cyclones in our historical record that went that quickly from a depression to a Category 5 hurricane.” That’s a big problem, because rapid intensification sets the stage for worst-case scenarios. Sadly, that’s what happened to the Caribbean island of Dominica on Monday night, hit by Maria at full Category 5 strength. There’s little chance to warn people or for them to prepare if rapid intensification occurs, so forecasters naturally want to be able to have a handle on it — but it’s a struggle..."

Hurricane Maria Does "Mind-Boggling" Damage to Dominica, Leader Says. The New York Times has details.

The Best for Hurricane Irma Came From a Computer Model Few People Knew About. GFS, ECMWF and...Panasonic model? Here's an excerpt from Capital Weather Gang: "Of the massive, high-powered computer models run by governments and institutions to forecast hurricanes, the vaunted European model had the best performance during Irma. But there’s a little-known entity that preliminary data show outperformed the European model as well as the others. Enter Panasonic, the electronics company best known for making televisions. Panasonic has a subgroup in its aviation division, known as Panasonic Avionics, that works on a weather model. The model’s foundation is based on the National Weather Service’s well-known Global Forecast System model, often referred to as the American model..."

One Lesson of Harvey: Read the Fine Print. Read this story from Dallas News and try not to shake your head in wonder: "They sat tucked away in a Fort Bend county clerk's file for the past two decades: 25 words on a public document that could have spared thousands of homeowners from losing everything. If only the homeowners had seen them. In the finest of fine print, the county warned in 1997: "This subdivision is adjacent to the Barker Reservoir and is subject to extended controlled inundation under the management of the U.S. Army Corps of Engineers." In other words, during a major storm, the corps could choose to flood the subdivision in an effort to protect greater Houston. Which is exactly what happened during Hurricane Harvey. Now, as Houston begins a massive recovery effort projected to cost as much as $180 billion, it is increasingly clear that government officials at every level did little to warn residents in some of the hardest-hit areas that they were buying into risk — living in areas designed to flood..."

What if an Irma-Like Hurricane Hit the New York City Area? As the Atlantic continues to warm the idea isn't quite as far-fetched as it might sound. Here's an excerpt from Bloomberg: "It sounds like a Hollywood disaster movie. A Category 5 hurricane churning in the mid-Atlantic suddenly veers northwest -- and heads straight for New York City. The good news is that, for now, experts agree a Cat 5-sized deluge appears to be a meteorological impossibility in the U.S. Northeast, given today’s sea temperatures and weather patterns. The bad news: A storm doesn’t need to pack the wallop of a Harvey or an Irma to knock out the region. Superstorm Sandy, whose wind speed was a relatively tame 80 miles per hour when it reached New Jersey, did $70 billion of damage in October 2012. Irma made landfall in Puerto Rico at 185 mph. But if there’s anything we know about climate change, it’s that the boundaries of what’s possible keep shifting. As yet another hurricane, Jose, grinds up the Eastern Seaboard, the black-swan scenarios offer alarming perspective..."

Despite Rising Seas and Bigger Storms, Florida's Land Rush Endures. It's a tropical paradise, until it's not. Here's an excerpt from The New York Times: "Florida was built on the seductive delusion that a swamp is a fine place for paradise. The state's allure - peddled first by visionaries and hucksters, most famously in the Great Florida Land Boom of the 1920s - is no less potent today. Only, now there is a twist: Florida is no longer the swampy backwater it once was. It is the nation's third most populous state, with 21 million people, jutting out precariously into the heart of hurricane alley, amid rising seas,  at a time when warming waters have the potential to bring ever stronger storms. And compared with the 1920s, when soggy land was sold by mail, the risks of building here are far better known today. Yet newcomers still flock in and buildings still rise, with everyone seemingly content to double down on a dubious hand..."

The Stunning Price Tags for Hurricanes Harvey and Irma, Explained. Good for the economy (new construction!) Depends on who you ask - certainly not a positive for those starting over. Here's an excerpt from Vox: "Estimates for the cost of Hurricane Harvey’s damage have come in at $65 billion, $180 billion, and as high as $190 billion — the last of which would make it the costliest disaster in US history. The numbers from the second record-breaking storm that hit the US this summer, Hurricane Irma, meanwhile, are still rolling in. But totals range from $50 billion to $100 billion. To appreciate how staggering these figures are, consider that they could be enough to make the $18.57 trillion US economy lose a step, knocking between 0.6 percent and 0.8 percent off of US GDP growth this quarter, according to projections from investment banks..."

What If America Had a Detective Agency for Disasters? WIRED.com asks the rhetorical question: "...A bigger problem: “There’s no such thing as a ‘disaster,’” Brilliant says. A famine is not a flood is not an explosion is not a refugee crisis is not a disease outbreak. “Each one has its own particular ways to screw up.”Corporate forces would resist this new agency even harder than anti-bureaucratic ones. The FIRE sector—the finance, insurance, and real estate industries—has become the biggest contributor to federal-level political campaigns. That lobby doesn’t want to hear about uninsuring coastlines or rezoning wilderness. “I call them the lending complex,” Knowles says. “They’re going to push back on this because they think we should be able build anyplace—wildland interface, Jersey Shore, wherever...”

Study Finds FEMA Flood Maps Missed 75% of Houston Flood Damage Claims Between 1999 and 2009. A story at Forbes caught my eye: "A recent study found that FEMA failed to capture 75 percent of flood damages within their flood maps between 1999 and 2009. The FEMA flood maps are the primary source for how the government and insurance companies evaluate flood risk and insurance premiums. There are collectively trillions of dollars worth of property that rely on these maps being accurate. The study, conducted by Rice University and Texas A&M University in Galveston, analyzed flood claims between the years of 1999 and 2009 during which there were five major floods. Each of these five floods did not meet the 100-year flood criteria and thus the FEMA flood maps which are based on 100-year floods should have been sufficient to cover Houston residents..."

How to Avoid Cars With Flood Damage. CNET has some timely advice: "...Here's a quick checklist for avoiding soggy vehicles: 

  • Examine the car's title. Any reputable dealer or seller will let you know the car has a Salvage or Flood branded title from water incursion. That's establish on the car's state record once an insurance company has made that declaration. Note that this entire scenario has a big loophole:
  • Cars that never saw an insurance adjuster, either because they weren't insured or the owner knew what would happen when a claim was made on a flooded car, may end up on the private market after being dried out and cleaned up.  This non-insurance loophole is one of the most troublesome.
  • Check the National Motor Vehicle Title Information System, NMVTIS, which is a free online database run by the DOJ..."

10 Costliest Hurricanes in U.S. History? NOLA.com in New Orleans takes a look; number one on the list is Katrina: "The 10 costliest hurricanes in U.S. history, even when damage estimates are adjusted for inflation, all occurred in the past 30 years. All but two of them struck in the 21st century. The storms hit Florida (6), Louisiana (4) and Texas (2), as well as Alabama, Mississippi, New Jersey, North Carolina and South Carolina (1 each). Most of the big ones struck more than one coastal state. But it’s not just coastal states where costs mount. Once a hurricane comes ashore and weakens, cut off from the warm seawater that fuels it, it still carries immense amounts of moisture. As it moves hundreds of miles inland and breaks up, it continues to dump that moisture in the form of phenomenal rain that floods creeks and rivers, causing even more damage..."

Most Intense Atlantic Hurricanes? In terms of central pressure Wilma is at the top of the list with a pressure of 882 MB measured in the eye back in 2005. As of last night Maria was the 10th most intense hurricane ever measured in the Atlantic basin.

Earth Sweltered to 3rd Hottest August, Summer on Record. The AP has details: "Earth just sweated through the third hottest August and summer on record. The National Oceanic and Atmospheric Administration said Monday the globe last month averaged 61.5 degrees (16.43 Celsius), which was a degree-and-a-half higher than the 20th century average, but behind 2016 and 2015. The average temperature for June through August was 61.47 degrees (16.41 Celsius).

Editorial: Don't Cut NOAA. Yes, this might be a bad time to take a hatchet to NOAA's budget. For the price of a tall, soy vanilla latte you have access to what are consistently the most accurate, reliable weather forecasts and severe weather warnings in the world. Here's an excerpt from SavannahNow: "...While the national debt is real, and Congress and the president must do a better job of working together to cut waste and improve efficiency and bring fiscal sanity to Washington, there are better places to cut spending. Don’t cut agencies like NOAA that help keep this nation safe from hurricanes, at relatively low cost. NOAA’s annual budget is currently $5.6 billion, a small fraction of the federal government’s $1.2 trillion discretionary budget. The National Weather Service costs each American about $3 per year, the agency said on its website. Three bucks a head is a bargain for data that provides a great value to the public. If the accuracy of hurricane tracking could be improved, most Americans probably would be willing to pay even more..."

AP Exclusive: Evidence of Spills at Toxic Site During Floods. Details via the Associated Press and Washington Post: "The U.S. government received reports of three spills at one of Houston’s dirtiest Superfund toxic waste sites in the days after the drenching rains from Hurricane Harvey finally stopped. Aerial photos reviewed by The Associated Press show dark-colored water surrounding the site as the floods receded, flowing through Vince Bayou and into the city’s ship channel. The reported spills, which have been not publicly detailed, occurred at U.S. Oil Recovery, a former petroleum industry waste processing plant contaminated with a dangerous brew of cancer-causing chemicals. On Aug. 29, the day Harvey’s remnants cleared out, a county pollution control team sent photos to the Environmental Protection Agency of three large concrete tanks flooded with water. That led PRP Group, the company overseeing the ongoing cleanup, to call a federal emergency hotline to report a spill affecting nearby Vince Bayou..."

10 Giant Companies Commit to Electric Vehicles, Sending Auto Industry a Message. InsideClimate News has the story: "A coalition of global corporations, including Unilever, Ikea and shipping giant DHL, launched a global campaign today to accelerate the shift to electric vehicles and away from gas- and diesel-powered transportation—which generates almost a quarter of energy-related greenhouse gas emissions worldwide and has been the fastest growing emissions source. Since more than half of the cars on the road belong to companies, the new EV100 coalition could have a major impact. It aims to do for EVs and electric car charging infrastructure what coalitions such as the RE100 are already doing to encourage corporate purchasing of clean energy (and thus motivating development of new solar and wind power). EV100's goal is to send a signal to automakers that there is mass demand for electric vehicles before 2030, when current forecasts suggest global uptake will start to really ramp up..."

Utilities Line Up to Profit from "Slowest Trainwreck" in History. Bloomberg reports: "...Renewable energy technologies are upending the century-old, centralized business model that that utilities have used to grow. The cost of electricity from offshore wind farms, once one of the most expensive forms of green energy, is expected to slide by 71 percent over the next two decades, according to BNEF. Solar, once so costly it only made sense in spaceships, now competes with coal and even natural-gas plants on cost. “I do think we’re experiencing the slowest trainwreck in history,” Steven Martin, chief digital officer at General Electric Co.’s energy connections unit, said at the conference. “We’re going to reach some point where the marginal cost of energy is zero.” Earlier this year, Germany shocked the renewable energy industry by handing out contracts to developers willing build offshore wind farms without subsidy. Spain has also seen zero subsidy tenders, according to Starace, who said he expects the trend to go global after beginning in Europe..."

Why I Hitchhiked the Rust Belt in Search of the American Man. The Guardian has a poignant piece; here's a clip: "...In the US, a man’s value has long been based almost solely on one thing: his ability to put food on the table via his paycheck. With blue-collar work vanishing, underemployment rampant and the gig economy ascendant, the nature of traditional work is changing.It follows that this is also altering the American idea of masculinity. Precisely because people are often so forthcoming with hitchhikers, we thought it would be a good method to discuss the softer, more vulnerable side of American manhood – a topic often hidden behind innuendo, bravado and posturing. Over dozens of interviews, we found people struggling heroically under the relentless grind of American capitalism. We found there are jobs to be had, but few that pay a living wage or offer time with family. As one man put it: “There are jobs, but none of them pay good...”

The campaign claims that, under Article 1 of the 1993 Montevideo Convention on the rights and duties of states, a country must be able to: define a territory, form a government, interact with other states, and have a permanent population. The Great Pacific Garbage Patch has borders (sort of), and it’s easy to create a government and institutions for interacting with others..."

Are You Emotional on Airline Flights? There May Be a Scientific Reason. BBC reports: "...One major airline has gone as far as issuing “emotional health warnings” before inflight entertainment that might upset its customers. There are many theories about why flying might leave passengers more vulnerable to crying – sadness at leaving loved ones, excitement about the trip ahead, homesickness. But there is also some evidence that flying itself may also be responsible. An emerging body of research is suggesting that soaring 35,000ft (10km) above the ground inside a sealed metal tube can do strange things to our minds, altering our mood, changing how our senses work and even making us itch more...The reduced air pressure on airline flights can reduce the amount of oxygen in passengers’ blood between 6 and 25%, a drop that in hospital would lead many doctors to administer supplementary oxygen...There are some studies, however, that show even relatively mild levels of hypoxia (deficiency in oxygen) can alter our ability to think clearly..."

Standing at Work Is Just as Unhealthy as Smoking Cigarettes Daily, Study Says. I know, I was a little dubious when I saw this Newsweek headline too: "Sitting at a desk all day will slowly eat away at one’s health—countless studies over the years have reaffirmed this common assumption. Standing desks have become a popular solution to the sedentary lifestyle global workforces have created, but unless they have an option for sitting, they may not be a much healthier option. In fact, those who typically stand at work for prolonged periods are more likely to face cardiovascular and other health risk factors, according to a study published in the September issue of the American Journal of Epidemiology. Researchers tracking more than 7,000 study participants in Ontario, Canada, within a 12-year period found that people who often stood at work were nearly twice as likely to develop heart disease, compared to those who typically sat throughout their shifts..."

China's Camel Milk Mogul. Hung over? Try camel milk. No, I didn't know that either.

They are supposed to erase the effects of half a bottle of moonshine, supposed to prove that their nutrition is so magnificent that there nothing it can’t overcome, not even a baijiu stupor. The cure is so effective, Chen says, that it turns his salesmen into superhuman drinkers, and so he prevents them from taking camel milk to restaurants, lest they cause havoc with lesser drinkers. There was no such ban on our dinner. Two cases of milk are propped against a wall. I pull the tab on top of the silver can and chug. It tastes mostly of dairy, with a slightly animal whiff.

When It Comes to Sex, Dating and Drinking, Teens Are Doing Much Less Of It. Quartz has the surprising details: "Being a teen isn’t what it used to be. According to a huge new study, adolescents in the 2010s were less likely date, drink alcohol, go out without their parents, and have sex than teens in every generation since the 1970s. Fewer of them have paying jobs or drive. The research, published in Child Development, says the cause is not kids having more homework, or more extracurricular activities. (They are actually doing less homework and about the same in terms of extracurriculars.) What’s changed is the context in which teens are growing up. Parents are more invested in teens’ lives. They have smaller families, which means more attention and money to spend on each kid..."

September 21, 2005: An unusually intense late season severe weather event affects parts of central Minnesota and west central Wisconsin during the late afternoon and evening hours. Baseball-sized hail, damaging thunderstorm winds, and tornadoes result from several supercell thunderstorms. The most widespread damage occurs across the northern and eastern portions of the Twin Cities. Three tornadoes rake across parts of Anoka and northern Hennepin counties, including an F2, but the tornado damage is overshadowed by the widespread extreme wind damage associated with the rear flank downdraft of the supercell. In addition to the severe weather, many locations received substantial amounts of rain. Many streets and underpasses in the northern Twin Cities metro area were flooded Wednesday night, where radar precipitation estimates were in excess of 3 inches.

September 21, 1994: 1/2 inch hail in Blue Earth County results in $6 million in crop damages.

Republican Senator Endorses "Price on Carbon" to Fight Climate Change. TIME has the details: "Sen. Lindsey Graham endorsed a "price on carbon" to fight climate change, breaking with much of the Republican Establishment. Speaking at a climate change conference held by former Secretary of State John Kerry at Yale University, the South Carolina Republican called for a "price on carbon," saying he would take the idea to the White House for consideration. "I'm a Republican. I believe that the greenhouse effect is real, that CO2 emissions generated by man is creating our greenhouse gas effect that traps heat, and the planet is warming," said Graham.

I'm a TV Weatherman. Here's What Happened When I discussed Climate Change on the Air. Sean Sublette reports for Vox: "...In 2014, after nearly 20 years as a broadcast meteorologist, I saw a change in both the climate and the broadcast meteorology landscape. On the climate front, I knew evidence of climate change would only become stronger. On the broadcasting front, it seemed more meteorologists wanted to approach climate change on air, although some struggled with how to go about it. In both cases, my gut was right. The planet has set a record for its warmest year for three years running. Intense heat waves and rising seas have taken a toll around the world as atmospheric carbon dioxide continues to rise to levels unseen in the history of human civilization. Evidence of a shift in attitudes became clear in surveys of broadcast meteorologists. In 2010, a George Mason University survey indicated that 53 percent of broadcast meteorologists say global warming is indeed happening. A similar 2017 survey indicated that number had jumped to 95 percent. However, that same 2017 survey only indicated 49 percent were convinced it has been mostly or entirely due to human activity, so there is still work to be done to bring the science home..."

Joe Romm explains at ThinkProgress: "...A 2015 study on the impact of sea-surface temperatures on the intensity of hurricanes in the North Atlantic found “intensification increases by 16 percent for every 1°C increase in mean SST.” And a 2016 study warned that “the vast majority (79 percent) of major storms” are rapid intensification storms,” and “the most intense storms” are those that undergo rapid intensification. So it’s no surprise that Harvey spun up from a tropical depression to a Category 4 superstorm in two days. Or that Irma saw a “rapid intensification burst,” as meteorologist Jeff Masters described it. It’s also no surprise that the most prominent climate science deniers would like scientists to stop talking about the link between human-caused climate change and more intense hurricanes..."

Climate Change Brings Melting Ice, and Cruise Passengers, to Canada. USA TODAY has the details: "When a massive luxury cruise ship docked outside the tiny Inuit town of Cambridge Bay this summer, it doubled the population of the town for a day. “It was just jaw-dropping to think that the same amount of people that are in Cambridge Bay could fit onto that ship,” said Mia Otokiak, 21, a lifelong resident of the small, largely Inuit town in the Canadian province of Nunavut. The Crystal Serenity, a 13-deck cruise ship carrying more than 1,700 passengers and crew, stopped there this August for the second time during a repeat of its historic 2016 voyage through the Northwest Passage. The Serenity is by far the largest passenger ship ever to ply the waters of the Northwest Passage, from Alaska through the Canadian Arctic Archipelago and on toward Greenland..."

Arctic Sea Ice Reaches 8th Lowest Annual Minimum. Arctic Now has details: "Arctic sea ice extent reached an annual minimum of 4.64 million square kilometers (1.79 million square miles) on Sept. 13, according to the National Snow and Ice Data Center in Boulder, Colorado. This represents the eighth lowest extent in the 38-year satellite observation era and a slight increase over 2016 which recorded a low of 4.14 million km2. However, it continues the trend of substantially reduced ice coverage in comparison to the 1970-1990s, when summertime minimums were in excess of seven million km2..."

It Takes Just 4 Years to Detect Human Warming of the Oceans. 92% of the additional warmth from heat-trapping greenhouse gases is going into the world's oceans. St. Thomas scientist John Abraham authors an article at The Guardian: "...According to our analysis, the top 10 warmest years of ocean heat content are all in the most recent decade (following 2006) with last two years being the hottest. The heat storage in the ocean corresponds to 3×1023 Joules (a 3 with twenty-three zeroes after it) since 1960. Prior to the 1980s, values are not as well known, and the global record is unreliable prior to about 1960. In the most recent 25 years, the Earth has gained approximately 0.7 Watts for every square meter of surface area. That may not sound like much but think about how many square meters are required to cover the surface of the Earth. To put these numbers in perspective, the heat increase in the oceans since 1992 is about 2000 times the total net generation of electricity in the USA in the past decade..."

How Watching Football Helped Me Understand People Who Deny Climate Change. A little perspective from The Washington Post: "As a science journalist who has written about climate change for a quarter century, I’ve struggled to understand climate change deniers. How, I wondered, could a group of otherwise intelligent people reject the clear and growing scientific evidence that the planet was warming, climate systems were going haywire, and human activities were at the root of the problem? Then, as the new NFL season kicked off last week, I realized I was a science denier, too. Even in the face of mounting evidence that football is hazardous for players’ brains, I couldn’t stop myself from watching. I cheered gleefully as the Patriots lost on opening day Thursday Night Football and my Broncos prevailed on Monday Night Football, kicking off the Super Bowl LII season. How different am I from people who put their skeptical heads in the sand and keep burning fossil fuels like there’s no next season? If I deny the neuroscience about the long-term implication of banging heads for sport, then I can continue being a fan, right?..."

Extreme Weather: What's Climate Change Got To Do With It? Here's an excerpt of an answer from World Resources Institute: "...We also know that warming leads to higher sea levels, which in turn increases the risk of storm surge, contributing to the damage brought by hurricanes. Climate change also warms oceans, adding energy that can fuel coastal storms. Compounding this, a warmer atmosphere can hold more moisture, so there can be more moisture for storm systems, resulting in heavier rainfall. The U.S. National Climate Assessment finds that there has been a substantial increase – in intensity, frequency, and duration as well as the number of strongest (Category 4 and 5) storms – in Atlantic Ocean hurricanes since the early 1980s, linked in part to higher sea surface temperatures. By late this century, models on average project a slight decrease in the number of tropical cyclones each year, but an increase in the number of the strongest (Category 4 and 5) hurricanes and greater rainfall rates in hurricanes (increases of about 20 percent averaged near the center of hurricanes)..."

Rebuttal: Climate Change is a Life, Liberty and Property. An Op-Ed at The Washington Examiner got my attention: "...Rogan talks about the foundation of our democracy. What he omits is that in the Fifth Amendment, the founders recognized the fundamental right of citizens to be free from government actions that harm life, liberty, and property. Our nation's climate system, including its atmosphere and oceans, is tightly tied to this right. James Madison, who drafted the constitution, said in 1818: "The atmosphere is the breath of life." In Texas and in Florida, we just saw our climate, infused by fossil fuel-created carbon pollution, infringe upon the inalienable right to life, liberty, and property. One of my co-plaintiffs, 10-year old Levi, lives on a barrier island in Florida. The federal government's contribution to our climate crisis, with the cooperation of the fossil fuel industry, directly violates this right, especially us as young people..."

Yes, Climate Change Made Harvey and Irma Worse. A consistenly warmer ocean didn't trigger the storms, but there's a high probability it amped them up, juiced them into stronger hurricanes. That, and higher sea levels magnified the storm surge associated with each storm. CNN reports: "The right time to talk climate change is now.It might seem premature when people in the Caribbean, Florida and Texas are still mucking out their flooded homes. And no, changes in our planet's atmosphere did not cause Hurricanes Harvey or Irma. But the consensus among scientists is that the effects of climate change, such as rising sea levels and warmer oceans, made those storms far more destructive than they would have been in previous decades. "The short version is, climate change makes these very bad storms worse," said Sean Sublette, a meteorologist with Climate Central, a nonprofit group that studies climate change. "It's not the approximate cause of the storm, but it makes these bad storms worse. And in the case of a really bad storm, climate change can make it totally disastrous or catastrophic..."
