In Search of Nature (from Hot White Snow)

Beaver damageRecently I marveled at the nature around us, and then today I realized how much of it is no longer there. This point was emphasized as I read the following:

Most of us live in cities where the number of visible wild species was long ago winnowed down to a few dozen. The sight of anything wilder than a sparrow, pigeon, or a squirrel makes the hearts of urban dwellers soar like the eagles we nearly exterminated.

The quote is from a book called Fire in the Turtle House by Osha Gray Davidson. The focus is on the plight of the green sea turtle in Hawai’i, but this line resonated with me in a more personal sense. I commonly walk from our suburban townhouse over to a small pond surrounded by woods. “Woods” in this case is defined as the residual trees and underbrush remaining after developers have decimated the natural forest and replaced it with townhouse farms, groups of homes that have grown like corporate cornfields in this area of northern Virginia.

Still, I live for these walks. The robins, cardinals, mockingbirds, occasional sparrows, and rare wrens are joined each spring and summer by swarms of geese, many with new families that we matronly watch over as they grow through their baby down into adolescent feathers. We watch as the toothy shavings of yet another small tree reveals the nightly work of an unseen beaver. A green heron makes an appearance in search of food. The occasional great blue heron does indeed make my heart soar.

The Pope’s Climate Encyclical and Why Climate Deniers are Their Own Worst Enemy (From The Dake Page)

Pope climate encyclicalIt should go without saying that when you deny reality long enough, eventually reality makes you look foolish. Climate deniers have been denying the science behind man-made climate change for so long that they have lost even the illusion of credibility. They have become their own worst enemy, and as such have put themselves on a path of complete irrelevancy.

Deniers have chosen this path, of course. By blatantly denying even the most basic science and by egregiously promoting the most obvious and ludicrous falsehoods, deniers have marginalized themselves to the point of inconsequentiality. Deniers now find themselves being taken as seriously as Donald Trump’s presidential run. Yes, they have become that buffoonish.

And alone.

Deniers used to hide behind ideological blinders, seeking protection for their anti-science beliefs in the arms of “conservatives,” the “religious,” and “Republican” comfort groups. Now deniers find themselves in a category among themselves. In contrast, intellectually honest and informed people who identify within these traditional labels no longer provide cover for denial.

Religions do not condone denial of the science

This point is brought home as Pope Francis, leader of the world’s 1.2 billion Catholics, issues the Vatican’s papal encyclical on climate change and the environment. [Here is a summary of the main points; and here is the full letter, in English] In it the Pope acknowledges the unequivocal science demonstrating human activity is causing our climate to warm, and that the changes observed and coming present a significant risk to humanity.

Let me stop here and reinforce this to make it clear, because this is a point that climate deniers have intentionally tried to confuse as they attack the Pope.

Tesla and Electric Cars in Scandinavia

More and more I see electric cars around the United States, mostly the obvious ones like the Tesla Model S and an occasional plug-in hybrid like the Chevy Volt, plus the obvious non-plug-in hybrids like Toyota Prius. But this pales to the number of electric cars that I saw in Norway, Denmark, and Sweden. One reason – access to charging stations.

Tesla car

Elon Musk has been working hard to install charging stations throughout the major driving corridors of the US. The government has not been all that helpful in that regard; in fact, because of oil and auto manufacturer lobbying (and Congress’s inability to function), our government inaction still works against the widespread distribution of electric cars. Europe has taken the opposite approach.

Electric cars in Oslo

In Copenhagen, there were a couple of charging stations right next to the famed city hall. In Stockholm, charging stations were also present, while in Oslo they have put a huge focus on electric vehicles. The photo above shows charging stations lined up and down both sides of the street. Interestingly, this particular spot was up against the old stone fortress walls made so famous in Jo Nesbo books. It shows that the old and new are compatible.

Norway EV Sales

While it was nice to see so many Tesla Model S cars, the predominant electric vehicle (EV) was actually the Nissan Leaf. According to Clean Technica, the Leaf has grabbed a huge lead in market share in Norway. The graphic above shows that Leaf sales made up 55% of the total EV sales in January 2014, almost four times the next electric car (Volkswagen’s e-Up!) and almost five times the Tesla Model S. Fully electric vehicles (EVs) dwarfed the number of plug-in hybrid electric vehicles (PHEVs) in Norway (and in Denmark, where 100% of EVs were full plug-ins). Oddly enough, PHEVs were ahead of full EVs in Sweden, in part because of the popularity of Mitsubishi’s Outlander PHEV and the lack of availability of the Tesla Model S.

Besides the greater environmental awareness of Scandinavians compared to Americans, drivers in Sweden, Denmark, and Norway already have access to the type of electrical sockets needed for EVs. These countries also offer much better financial incentives to help drivers move away from fossil fuel based engines to more sustainable engine technology.  They have also done a better job at facilitating charging stations, most of which are free to the public.

As you’ll see in that last link, charging stations for EVs and PHEVs are starting to appear in more and more places in the US as well, which should mean faster adoption of electric and hybrid vehicles in the near future. Eventually, all our vehicles may be EVs. That would go a long way to reducing our dependence on oil-based energy and our contributions to man-made climate change.

I’ll have more science traveling updates from Scandinavia, as well as from the Everglades, Yosemite, Argentina, and the other places I’ve visited since I embarked on this new career. Stay tuned (and feel free to wander around previous posts by clicking on “Travel” in the category list below).

The People’s Republic of Chinese Chemicals and The Puppet Suit

No, this isn’t the name of some bizarre new Chinese opera or dance troupe, it’s a mashup of two new posts on The Dake Page and Hot White Snow. The former has a book review of The People’s Republic of China Chemicals; the latter a response to a microfiction writing prompt. Excerpts are below with links to the full originals.

Peoples Republic of ChemicalsBook Review: The People’s Republic of China Chemicals by William J. Kelly and Chip Jacobs (The Dake Page)

An important book, poorly written. The People’s Republic of China Chemicals purports to reveal how the offshoring of American manufacturing to China helped China become the most polluted country on the planet. It does achieve that goal, though perhaps in spite of itself. While the title suggests a discussion on chemicals, the vast preponderance of the book is focused on the massive air pollution problems in China. This isn’t surprising given the authors’ previous collaboration, a book about the smoggy days of Los Angeles.

The early chapters provide some historical background on China’s dynastic rule and frequent invasions by the Japanese, the British, and others, as well as its own political infighting. Their overly rosy characterization of Mao’s various attempts to control everything once he and the communists took over is somewhat naïve – or at the very least, incomplete – but they generally capture the essence of how China came to set itself up as the world’s factory. The authors’ explanation of how entry into the World Trade Organization (WTO) and various bilateral and multilateral trade agreements spurred the rapid growth of industry and economy, while perhaps overly rancorous, is well done.

In short, the book documents through rapid-fire detail and personal anecdote the rise of Chinese manufacturing and with it the extraordinary increase in coal-based pollution. The authors relate how bad the air pollution has become, and the subterfuge of the Chinese government to deny its existence even as giant screens in Tiananmen Square broadcast barely visible images of splendid panoramic vistas through the gritty air.

HalloweenThe Puppet Suit (Hot White Snow)

“Well, you clean up nice.”

Apparently she had never seen him in a suit before. But here he was, dressed up like some Wall Street tycoon in hopes of making an impression. Unfortunately, the interview hadn’t gone as well as the suit made him look. It was fine until the interviewer pulled out the puppets. Not what he expected for an investment firm, for sure. When the guy started using the puppets to explain how his firm and other “too-big-to-fail” firms had manipulated the global financial meltdown and still took multi-million dollar bonuses…

I walked out.

Nikola Tesla and Abraham Lincoln – Connected at the Players Club

Lincoln and Tesla Connected by Fate coverAs I’ve mentioned before, Nikola Tesla and Abraham Lincoln have a surprising number of connections between them. I’m currently writing about them in my new ebook called (unsurprisingly) Abraham Lincoln and Nikola Tesla – Connected by Fate, due out this summer on Amazon.com.

One unexpected, and somewhat ironic, connection revolved around key players in Lincoln’s assassination, at a club called The Players.

During his most socially-active period Nikola Tesla hung out with some of the more famous personages of the time. Among his friends were Samuel Clemens (aka, Mark Twain), John Muir, Robert Underwood Johnson, Sarah Bernhardt, and others. One of his favorite places to relax was The Players, a social club established to “bring actors into contact with men of different professions such as industrialists, writers and other creative artists.” Nikola Tesla was one of those men.

The Players, by the way, was started by famous Shakesperean actor, Edwin Booth. Yes, that Edwin Booth, older brother of the more infamous John Wilkes Booth, assassin of Abraham Lincoln.

Illegitimate son of the world-renowned actor, Junius Brutus Booth, Edwin went on to establish himself as a superior actor on his own. His two brothers, Junius Jr. and John Wilkes, equally illegitimate, also became actors, though one not as famous and the other more infamous. After the assassination, Edwin disowned John Wilkes and eventually resumed acting, making the title role in Hamlet his signature.

Edwin established The Players in 1888 and died in 1893 just as Nikola Tesla was lighting up the “White City” at the Chicago World’s Fair.

There is much more to the story, of course, and I’ll have that in Abraham Lincoln and Nikola Tesla – Connected by Fate. Watch for it on Amazon later this summer.

David J. Kent has been a scientist for thirty-five years, is an avid science traveler, and an independent Abraham Lincoln historian. He is the author of Tesla: The Wizard of Electricity (now in its 5th printing) and two e-books: Nikola Tesla: Renewable Energy Ahead of Its Time and Abraham Lincoln and Nikola Tesla: Connected by Fate. His book on Thomas Edison is due in Barnes and Noble stores in July 2016.

How Climate Scientists Can Communicate the Science to the Public (from The Dake Page)

Huh CommunicationLast week we took a look at how climate scientists can communicate the science to policy-makers, so today in Part 3 we’ll look at how scientists can communicate directly with the public. Together these are a three-part series on how to communicate climate science to all three target audiences – other scientists, policy-makers, and the public.

Communicating with the public is actually the most important of the three target audiences, and the one that scientists are least likely to have spent much time doing in their careers. And that’s a shame because policymakers (notwithstanding the disproportionate influence of lobbyists and rich campaign donors) are most influenced by public opinion. It is the public who are the real drivers of change. It is they who give policymakers permission (or pressure) to take action. If enough of their constituents demand action, they will act.

But reaching out to the public is inherently more difficult for scientists. Scientists, like all professionals, have usually spent considerable time (and expense) getting specific education, training, and life experience in their area of expertise than the general public. In these days of specialization it seems we all have our expertise, whether it be in some climate related science, economics, brain surgery, law, plumbing, or bridge design. Each field builds up its own set of jargon, technical words that have specific meanings within their field but may have no meaning to anyone outside that field (or worse, mean something completely different outside the field).

So it’s critical to reach out to the public, but scientists have to do so in ways that can be understood and are meaningful. Here are a few examples, though this by no means should be considered an exhaustive list:

1) Speak at libraries, churches, schools, etc.: Talk about science in a church? Of course. I was recently in a church whose stained glass windows included one celebrating several of our greatest scientists – Albert Einstein, George Washington Carver, and others. Libraries, churches, and schools all have one thing in common – they are places where the community comes together to learn. Off to give a talk about your area of specialty.

Science Traveling in Scandinavia – The Route

By the time you read this I will be science traveling in Scandinavia. The trip will take us into three countries – Denmark, Sweden, and Norway. Somehow I missed these countries during my three years living and working in Brussels, Belgium, so I’m back to fill in the gaps.

Copenhagen

After a quick plane change in Amsterdam, our first stop is Copenhagen, Denmark, home of the iconic harborside houses above. Long besieged by Vikings (at least historically), and despite having huge oil and gas reserves in the North Sea, Denmark is actually leading the way with renewable energy from wind turbines.

Little Mermaid Copenhagen

A few days of exploring Copenhagen and environs and then it’s time to hop a speed train through the Swedish countryside up to Stockholm, Sweden, where we will be obligated to hike up to the Little Mermaid statue. [Note added on 6/2/15: Yes, the Mermaid is still in Copenhagen, not Stockholm. Somehow I got the landmarks jumbled when I wrote this and scheduled it for future posting and I didn’t have access to fix it from the road. Thanks, Betsy, for catching the error.] Like Denmark, Sweden’s history has had a huge historical Viking influence.

Norwegian Fjord

Another train from Stockholm takes us to Oslo, which is the beginning and the end of our Norwegian experience. We’ll spend a couple of days checking out the environs that induced “The Scream,” Edvard Munch’s iconic painting – which are actually four paintings – and we should be able to see at least three of them. We’ll also see, you guessed it, more Viking influence. From Oslo we take a winding train/train/boat/bus/train across the Norwegian interior and through the fjords before reaching the city of Bergen on the western coast. A day later we’re back on the train to Oslo to catch the flight home (via Frankfurt, Germany).

During all of this I’ll have my laptop so that I can be writing up the experiences during the long flights and train rides. As is my usual pattern, I’ll be looking for sciencey stuff along the way (how did those fjords come to be, anyway?). Internet access will be sporadic but I’ll plan to post photos here and on Facebook whenever I get a chance.

Watch this space for more on Scandinavia.

Book Review – Tesla’s Signal by L. Woodswalker

Tesla's SignalAs a writer it’s always interesting to read other people’s writing, especially when they are people I know. Of course, interesting could mean either good or bad depending on the quality of the writing, but it seems I’ve been lucky because the books I’ve read by friends and acquaintances have been wonderful. That includes works by Thomas Waite, R.C. (Chuck) Larlham, Sam Hawksworth, and the many Abraham Lincoln scholars I’ve met.

The most recent is L. Woodswalker, author of Tesla’s Signal. I first met Laura at a Tesla Memorial Conference at the New Yorker Hotel and then at subsequent Tesla events, including this one at the Chester County Library (Laura is in the second photo, another Tesla author Howard Lipman is in the third photo). I was presenting my book, Tesla: The Wizard of Electricity (now with 50,000 in print) and Laura mentioned that she was working on a science fiction novel based on Tesla’s life. That book came out this past month and I had the privilege of being one of the first to read it. Here’s my review as posted on Goodreads and Amazon:

Marvelous science fiction. L. Woodswalker authors a cleverly written exploration of alien invasion that masterly weaves real history with fantasy and surreality in a series of intricately woven story lines. Those who are familiar with Nikola Tesla will recognize the deft intertwining of Tesla’s real inventions, quirks, and personality traits with extrapolations to what they have become in the minds of many a Tesla aficionado. Those unfamiliar with Tesla will still find themselves rabidly engaged in the requisite alien races, the fight between good and evil, and some surprising romantic tension spliced into exciting action. All together here are the makings of a great SF novel. Well done!

I should note that I’ve been a scientist for my entire life and grew up as an avid science fiction and science fantasy fan. The focus of my own published writing means I read a lot more non-fiction these days, but I was happily surprised at how much I liked this book. The writing is tight and the blending of Tesla’s reality and fantasy is exceptional.

If you like Tesla, this will be a fun read. If you like alien beings, this will be a fun read. And even if you’ve never heard of Tesla and never met an alien being, it will still be a fun read. Find it on Amazon.com.

Meanwhile, I managed to meet my writing goal for my forthcoming book on Thomas Edison, so I’m comfortable taking some time off to go science traveling. More on that in my next post.

How Climate Scientists Can Communicate the Science to Scientists in Other Fields (from The Dake Page)

Huh CommunicationA few weeks ago we talked about how to communicate climate science to all three target audiences – other scientists, policy-makers, and the public. We touched on how scientists “do science,” i.e., through research, data analysis, conference attendance, and scientific publication. Today we’ll take a closer look at how scientists can communicate climate science to other scientists, including those scientists who specialize in other fields.

1) Publish the Research: As already noted, the main way for scientists to communicate the science to other scientists is to publish it in peer-reviewed journals. Doing so allows scientists to carefully lay out the premises, the methods, how the data were analyzed, the results, and the conclusions, all so other scientists can evaluate – and recreate – the work. I’ve discussed peer review in depth in previous posts. [Click on these links to read Part 1 (basics of peer review), Part 2 (when peer-review goes wrong),  Part 3 (abusing the system), and Part 4 (using the internet to bypass peer-review) of the series.] Once published, the research is further scrutinized, which may confirm or refute the work, and usually leads to more studies…and more publications. Many climate researchers, for example, have hundreds of peer-reviewed scientific papers (whereas most climate deniers have few, if any, peer-reviewed publications).

But think about the scientific publishing process for a moment. Like physicians, for example, where individual doctors may specialize in endocrinology, brain surgery, dentistry, or podiatry, scientists may specialize in astrophysics, archeology, biology, chemistry, mathematics, geology or dozens of other specialties. The more specialized the professional training and expertise, the greater the likelihood that a given scientist won’t be keeping up to date on advancements in other fields. A biologist is likely to have memberships and subscriptions to several biology-related organizations and journals, but may not be reading a physics journal discussing heat transfer in atmospheric systems.

This presents the dilemma that while journal publication is critical, it is largely focused on communicating with other scientists within your own field. That said, despite the tendency toward greater specialization, there is also a greater need for multidisciplinary collaboration. For example, ecologists looking at migratory patterns will see that those patterns are being modified by climate changes.

So how does one reach out to scientists in other fields?
