“Super Blood Moon” Tonight

What month is this again? I’m enjoying a super-sized August as much as the next guy; relieved it’s not snowing. Bad weather is good for business (sad but true) but I’m just fine with this lack of weather-drama.

Expect low 80s this afternoon (15F warmer than average) with a stiff south wind and a few whitecaps on your favorite lake. Amazingly nice for late September. A few showers may sprout tomorrow along the leading edge of Canadian air; midweek temperatures dipping into the 60s before mellowing near 70F by late week – comfortable sunshine next weekend as the brunt of rain stays south of Minnesota.

Within a week it’ll be cold enough for snow showers over New England and the Pacific Northwest, but nothing close to home as we limp into October.

Meanwhile you’ll want to check out tonight’s “super blood moon”. A full moon will plunge into Earth’s shadow, resulting in a total lunar eclipse lasting about an hour. An orange/reddish-looking moon may result during “totality”, from roughly 8-10 PM.

Check out the free show if you can because this won’t happen again until 2033.

Sunday Night’s “Super Blood Moon”. It may be a spectacular lunar eclipse, if the weather cooperates, the last one of these until 2013. here’s an excerpt from Discover: “…Every object in the solar system casts a shadow. Large objects, like Earth, create big shadows that can engulf entire worlds, even if those worlds loom bigger than normal. On the night of September 27/28, the Full Moon plunges through Earth’s shadow for the second time this year, and this time, it’s the biggest Full Moon of 2015. The resulting total lunar eclipse lasts more than an hour and occurs during the evening across the Americas…”

Cooling Trend. After peaking above 80F this afternoon Canadian air will (finally) push south. Nothing too chilly, but closer to average this week with highs mostly in the 60s. The brunt of any chilly air will push toward New England; Minnesota sees a glancing blow. Source: NOAA and AerisWeather.

Minor Correction. The models are all in pretty good alignment, showing low 80s by mid afternoon, followed by a cooling trend this week. No frost in sight – not yet. Source: Aeris Enterprise.

Soaking Rains South and East. NOAA’s 84-hour NAM guidance shows a risk of flash flooding from Pensacola to the Carolinas and the Appalachian foothills of Virginia, where some 4-5″ rainfall amounts are possible by Wednesday morning.

It’s Time. Just for laughs and giggles I thought I’d throw in the 240-hour accumulated snowfall map; expected snow accumulations between now and midday Tuesday, October 6. A little slush for Montana, but most of the snow falling well north of the U.S. border. Source: AerisWeather.

The Ultimate Cold and Flu Survival Guide. CNN has some timely tips on steps you can take to lower your risk of a nasty bug this winter; here’s a snippet: “Each year, the typical adult can expect to contract two or three colds, according to the Centers for Disease Control and Prevention. Skip the annual flu vaccine and you set yourself up for a bout of that as well. But it doesn’t have to be this way! Aside from good hand washing (with soap, for at least 20 seconds), “there’s a lot you can do to drastically cut your risk of getting sick,” says Holly Phillips, MD, a general internist in New York City. “And even if you do catch a bug, you may be able to cut short the duration of your illness.” Arm yourself with these tips from the experts, and make this cold and flu season your healthiest yet...”

Breathing By The Numbers: Real-Time Global Air Pollution Data. Here’s an excerpt of a story at onEarth: “…Last week, a staggering environmental health statistic emerged: Air pollution is responsible for about 3.3 million premature deaths every year, more than HIV/AIDS and malaria combined. The authors of the study noted that quantifying pollution’s toll has been difficult due to a lack of data. But the World Air Quality Index, a new interactive map that broadcasts air-quality measurements from around the globe in real time, is helping us see where in the world we need to clear the air. Based in Beijing, the project works with international environmental agencies to glean information from more than 8,000 government monitoring stations across 1,000 cities...”

I Survived the Deadliest Day in Everest’s History, and I’m Still Surviving It. Here’s an excerpt of a harrowing first-person account of a very bad day on Mt. Everest at Quartz: “…It wasn’t the kind of avalanche I’d seen footage of in documentaries, a billowy white plume traveling down a mountain’s face. This looked more like a tsunami—the unrealistic kind of tsunami you see only in Hollywood movies. It looked as if it was rising from the ridge and would barely touch the actual slopes of Pumori, instead hurtling through the air to a farther destination: us. Then Fhinju and Suber started running. I took one last glance at the apocalyptic cloud and turned on my heels to run with them. We didn’t get far. I myself hadn’t taken two steps when I tripped and fell flat on my face.…”

What Happens Next Will Amaze You. And possibly horrify you as well. Privacy on the Internet, being tracked by advertisers, worshipping a tech-elite while poverty and homelessness runs rampant. Check out a transcript of a recent presentation by Maciej Ceglowski at a tech conference in Copenhagen, Denmark; here’s an excerpt: “…Today we live in a Blade Runner world, with ad robots posing as people, and Deckard-like figures trying to expose them by digging ever deeper into our browsers, implementing Voight-Kampff machines in Javascript to decide who is human. We’re the ones caught in the middle. The ad networks’ name for this robotic deception is ‘ad fraud’ or ‘click fraud’. (Advertisers like to use moralizing language when their money starts to flow in the wrong direction. Tricking people into watching ads is good; being tricked into showing ads to automated traffic is evil.)…”

Always Wear Your Seatbelt In a Tornado. I have no idea where this was shot (Thailand?) but it’s a subtle, yet blunt, reminder that your seatbelt should be on at all times. I think the person who got sucked out of the vehicle is OK, but I have no other details. The video clip is quite remarkable, like nothing I’ve ever seen before. Almost like it’s CG from a Hollywood movie, but this YouTube clip was real.

Climate Stories….Because Weather & Climate are Flip-Sides of the Same Coin:

Microsoft Leads Movement to Offset Emissions With Internal Carbon Tax. Forward-thinking companies are already ahead of the curve; here’s an excerpt from The New York Times: “When Microsoft business unit managers calculate their profits or losses each quarter, they consider more than just sales and expenses. They also factor in the price of carbon. Even more radically, the business units are charged an internal tax by Microsoft based on their energy usage. The money goes into a common fund that invests in environmental sustainability projects. The company’s program is at the forefront of a fast-growing effort called carbon pricing…”

France Grapples With Future of the Alps: How To Ski or Climb Mountains in a Warming World. Here’s a clip from an article at Star Tribune: “…Researchers say the Sea of Ice is only the most accessible example of a problem the entire Alpine region is facing as warming mountainsides become more unstable and snowfall more inconsistent, threatening jobs and lives in a region heavily dependent on adventure tourism. Scientists have drilled the Mont Blanc region with sensor-equipped boreholes in recent years, hoping that measuring temperatures in the permafrost will give a sense of how quickly the problem is accelerating and which areas are most in peril…”

Researchers Reveal When Global Warming First Appeared. Here’s an excerpt of an interesting story at reportingclimatescience.com: “…Remarkably our research shows that you could already see clear signs of global warming in the tropics by the 1960s but in parts of Australia, South East Asia and Africa it was visible as early as the 1940s.” The reason the first changes in average temperature and temperature extremes appeared in the tropics was because those regions generally experienced a much narrower range of temperatures. This meant smaller shifts in the temperature record due to global warming were more easily seen. The first signal to appear in the tropics was the change in average temperatures. Later extreme temperature events showed a global warming signal…”

Pope Francis Tells Congress: Be Courageous, Do Something About Climate Change. Here’s an excerpt from Newsweek: “In his address to a joint session of the U.S. Congress Thursday morning, Pope Francis minced no words when it came to climate change. Referencing his recent influential encyclical on the environment, Laudato Si’, the pope called on the United States to make a “courageous and responsible effort” to “avert the most serious effects of the environmental deterioration caused by human activity…”

Pope Francis Addresses Congress: Full Remarks. Vox has a transcript of the Pope’s remarks on Thursday; here’s an excerpt focused on stewardship: “…In Laudato Si’, I call for a courageous and responsible effort to “redirect our steps” (ibid., 61), and to avert the most serious effects of the environmental deterioration caused by human activity. I am convinced that we can make a difference and I have no doubt that the United States – and this Congress – have an important role to play. Now is the time for courageous actions and strategies, aimed at implementing a “culture of care” (ibid., 231) and “an integrated approach to combating poverty, restoring dignity to the excluded, and at the same time protecting nature” (ibid., 139). “We have the freedom needed to limit and direct technology” (ibid., 112); “to devise intelligent ways of… developing and limiting our power” (ibid., 78); and to put technology “at the service of another type of progress, one which is healthier, more human, more social, more integral” (ibid., 112). In this regard, I am confident that America’s outstanding academic and research institutions can make a vital contribution in the years ahead...”

We Must United to Safeguard God’s Creation: Column. Four religious leaders have an Op-Ed at USA TODAY; here’s a clip: “…We also have the responsibility to act together for the common good, especially for those most vulnerable to the effects of climate change. Climate change and poor air quality are already posing risks to economic stability and human health. From increases in heat related deaths to higher numbers of asthma attacks, from lost job opportunities to increases in food prices, low-income communities, Indigenous communities and communities of color suffer disproportionately from climate change impacts, particularly in nations that lack the resources to help these communities adapt...”

Purdue Study: Climate Change Consensus Extends Beyond Climate Scientists. Here’s an excerpt of a press release from Purdue University: “A Purdue University-led survey of nearly 700 scientists from nonclimate disciplines shows that more than 90 percent believe that average global temperatures are higher than pre-1800s levels and that human activity has significantly contributed to the rise. The study is the first to show that consensus on human-caused climate change extends beyond climate scientists to the broader scientific community, said Linda Prokopy, a professor of natural resource social science. “Our survey indicates that an overwhelming majority of scientists across disciplines believe in anthropogenic climate change, are highly certain of these beliefs and find climate science to be credible,” Prokopy said…”
