Hearing Neil deGrasse Tyson — Science in today’s world

Neil deGrasse Tyson - Sioux Falls, SD

Neil deGrasse Tyson, speaking at the Boe Forum at Augustana University in Sioux Falls. All science related of course, getting sidetracked on some amusing other issues at times, but a great speech. My biggest takeaway…the need to restore humanity’s sense of wonder about the universe (and our own world).

We had the GREAT pleasure last night to hear Neil deGrasse Tyson speak at the “Boe Forum” at Augustana University in Sioux Falls.The Boe Forum on Public Affairs was founded in 1995, with a goal “to provide access to individuals who can address events, issues or problems of worldwide or national concern and of broad public interest.”  They’ve certainly had some wonderful speakers (and some less wonderful speakers…think Newt Gingrich and Rudy Guiliani) over the years. They’ve managed to draw some very big names, including Colin Powell, Mikhail Gorbachev, George H.W. Bush, Al Gore, Desmond Tutu, Vicente Fox, Sandra Day O’Connor, Pervez Musharraf, and Madeline Albright. Augustana University has just opened their new “Froiland Science Complex”, and said they wanted a “moonshot” science speaker to coincide with opening of that science center.  They certainly succeeded by managing to draw Neil deGrasse Tyson to Sioux Falls.

Tyson ended up talking for two hours, and while my son was getting a wee bit antsy towards the end, I must say that it was a very engaging, surprisingly funny, and interesting talk that kept me very engaged the entire time. There were a few things that surprised me a bit, things I disagreed with.  Given today’s political climate and how it’s affecting science, I was hoping for more content on the intersection of the two, but overall it was a terrific talk.  Some of the takeaways for me:

1968 – 1972 – Birth of the Environmental Movement — The highlight of the talk to me was a section where he specifically talked about the period of 1968 to 1972 and the profound effect it had on humanity and our country.  Apollo 8 was the first mission to orbit the moon, in 1968. As they rounded the moon, astronaut William Anders took the iconic “EarthRise” photo (bottom of this post), looking across the moon’s surface back at Earth.  The next year we landed on the moon. As Tyson noted, these events totally changed humanity and how we view our own planet.  Some very simple observations noted how little we understood our earth up to that point.  He showed a photo from Star Trek, of the Enterprise orbiting the Earth. Their depiction of Earth had the continents, the oceans…but no clouds!  Tyson gave other examples of artwork and even scientific renderings of Earth up to that point, and none of them portrayed the clouds that are always present! The sense of wonder during the space race, the first looks at our planet from space…it changed how we viewed our planet.  In the period from 1968 to 1972, you thus ended up with the establishment of the first Earth Day. The Environmental Protection Agency was founded.  The National Oceanic and Atmospheric Administration was founded.  We started cleaning up our air, our water.  We noticed the massive decline in our national symbol, the Bald Eagle, and banned DDT to save the species (a resounding success!).  The Endangered Species Act was founded in 1973.  This period STARTED the environmental movement.

Reinvigorating interest in science — The take-home point from the examination of the 1968-1972 period?  All that sense of wonder…that feeling that our Earth is a special place…that’s GONE, or at least incredibly diminished right now. Many people today simply can’t see past their own short-term guilty pleasures to even THINK about the future.  At the end of Tyson’s talk, he had a question-and-answer period. One of the questions was related to these points, and how we can get back to those days of the 1960s and 1970s where environmental conservation, where caring about our planet, really was part of the American consciousness. The answer from Tyson wasn’t related to politics, it wasn’t related to things like the March for Science coming up on April 22nd, it wasn’t related to need for better PR.  No, the answer was much more basic, and was rooted in k-12 education. We just don’t value science as much as we should in those formative years. As Tyson stated, what’s going to end up giving us a kick in the butt isn’t just a change in k-12 education, but a realization that we’re losing our economic competitiveness.  With education driven not by national-scale policy but local and state policy, the States that embrace science and technological innovation, starting in k-12, are the ones that will be competitive for industries that drive our economy. Given how much of a focus their is in this country right now on economics, money, and growth, the cynical side of me believes that it will be economic competitiveness that will end up re-igniting the interest and science and innovation, rather than any pure desire to invest in science for science’s sake.

Star Trek depiction of Earth

Prior to the famed “EarthRise” photo from 1968 and our landing on the moon a year later, humanity had little awareness of how to even portray our Earth. As Tyson noted, up until the late 1960s and the space race, this was a typical depiction of Earth (from the original Star Trek) series. Continents…check! Water…check!! Atmosphere, clouds, and weather…something’s missing! The space race had a profound impact on the way humanity viewed our own planet

Intersection of Science, Culture, and Politics — Speaking of the March on Science on April 22nd, one of the questions he received was about scientists and their role in activities such as this. Overall for the night, he really avoided politics, although there were a few timely, light jabs thrown in.  When the audience member asked this question, I thought we might finally hear his thoughts on the impact of politics on science right now. He did touch on that intersection, but it was different than I was expecting. He’s an educator, some may view him as an entertainer, but at his heart, he’s a scientist through-and-through.  His answer began by saying he was on the fence, that in his own mind, he’s still trying to decide how scientists should react in this kind of political environment.  But for the March itself, he said what he really hoped was that such an event wouldn’t be necessary.  As he hammered home all night long, science isn’t political.  Science provides its own truths, as as he stated, it doesn’t really give a damn what you think about it, what your personal, cultural, or political beliefs are.  In short, you can tell that what he’d like to have happen is that the science would speak for itself, that the knowledge and understanding we produce would stand on its own, and that humanity would return to a time where we’d base our decisions on that knowledge.  You can tell he’s struggling a bit with the issue, and is likely as bewildered as many of the rest of us as to how truth, how fact, are being ignored in the face of cultural, political, and ideological attacks. He definitely didn’t seem to have a clear answer on how scientists respond.

Human ego and science — Tyson ended his talk with a theme similar to his discussion of the 1968-1972 period, and its effect on humanity.  He talked about the “Pale Blue Dot” images, the first from Voyager One in 1990, where the instrument looked backed towards Earth and took an image representing our planet as tiny, pale blue dot in a sea of stars and emptiness.  The Cassini satellite studying Saturn provided a similar view more recently, with a 2013 image that shows Earth as a tiny blue dot hiding in the shadows below the foreground image of Saturn and its rings. The end of the talk itself was a reading of material from Carl Sagan, from his 1994 book “Pale Blue Dot”.  The following summarizes that material (a bit revised, from a talk Sagan gave that year):

We succeeded in taking that picture, and, if you look at it, you see a dot. That’s here. That’s home. That’s us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there – on a mote of dust, suspended in a sunbeam.

 

The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and in triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light.

 

To my mind, there is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly and compassionately with one another and to preserve and cherish that pale blue dot, the only home we’ve ever known.

Religion and Science — Tyson touched on topics related to the Sagan reference all night long. In the overall scheme of the universe, we’re insignificant. We’re not “special”.  At one point he listed the 5 most common elements in the Universe.  He then listed the most common elements in a human body. The list is identical, with the exception of helium (given it’s pretty much non-reactive, it doesn’t form elements found in the human body).  The point he makes…we’re just “stardust”, made up of the same common elements found throughout the universe.  On a night when he would occasionally brush up against the edge of talking in depth about the intersection of culture, politics, and science, but never really dive into the deep end of that pool, this may have been the most “controversial” part of the talk (particularly given that the talk was at a University associated with the Evangelical Lutheran Church, and was speaking in very “red” South Dakota). When touching on politics or culture, you can tell he tries very hard to avoid offending anyone, and he barely mentioned religion.  But as I listened to this part of the discussion, I did wonder what some of the more religious people in the room were thinking.  We’re not “special“.  We’re almost certainly not alone in the Universe, given that we’re made up of the same material as is found throughout the rest of the Universe. We live in a country, however, where a huge swath of the population is unable to separate the science, even the empirical world staring them in the face, from their religion.  In the end its a personal ideology that ends up driving the behavior and interactions of so many Americans, science (and reality!) be damned.  Overall for the night, in what would be interpreted to be a tough cultural and political setting for a science purist like Tyson, he did a great job walking the fine line of informing, without offending.

If you ever get a chance to see Tyson speak, it’s well worth your time.  He’s a wonderful speaker, with a rare ability for a scientist…he knows how to connect with people.

How much carbon dioxide in the atmosphere? Ssshhhhh….it’s classified

Atmospheric Carbon Dioxide

Trends in atmospheric carbon dioxide from pre-industrialization until today. We’ve gone from a baseline of 280 ppm to 404 ppm today, a level of atmospheric CO2 not seen in over 600,000 years. It’s irrefutable evidence of the impact man has had on the atmosphere and our climate. And now…evidently under the Trump administration, the level of atmospheric CO2 is classified information.

Science is in the news again!  Front page of the Washington Post, New York Times, and other major media outlets!! No, we haven’t discovered extraterrestrial life.  No, we haven’t found a cure for cancer.  In fact, there haven’t really been any earth-shaking research results published  No, the science-related stories that are capturing the front pages of major newspapers are those related to the muzzling of scientists in the federal government under the Trump Administration, after only 5 days.

It started on the 2nd day of the Trump administration.  Information on climate change was deleted from all White House website pages on Saturday, along with other issues that evidently aren’t important any more, such as civil rights.  Who needs to worry about civil rights, when we’re headed back to how it “should” be, with hairy old white men in charge of everything?  It’s all good!  In place of the climate change and LGBT information?  Melania Trump’s jewelry line. Yes, that’s right, a sales pitch for Melania’s jewelry literally is more important to the new administration than climate change or civil rights, and occupies space on the White House website.

Science and environmental research and reporting in the federal government was immediately under attack on other fronts as well.  This week Trump issued an executive order freezing all research grants and contracts at the EPA. All contract and grant awards, as well as all “task orders and work assignments”, are to be “temporarily suspended, effective immediately”.  It’s clearly the first step in dismantling regulatory activity at the EPA, with the Trump administration believing that regulation hinders business activity.  “Regulation”…you know…making sure you and your family don’t DIE or get sick just by breathing, drinking, and eating.  Minor little things like that get in the way of rich people making even more money, and we simply can’t have that.

Other federal agencies were instructed to halt “external communication”.  The Department of Health and Human Services has been instructed not to communicate “with any public officials”.  EPA was told to halt all press releases, blogs, or social media posts.  The U.S. Department of Agriculture was told to stop releasing any “public-facing documents”.  In other words, federal agencies have been instructed by the Trump administration to stop communicating with the public, to stop releasing results of the work that is done with taxpayer dollars.

Social media posts and press releases are a primary means by which federal agencies communicate with the public, and some bold renegade Feds today pushed the envelope on what’s now “allowed” in the Trump administration.  I say “push the envelope”, when in fact, all they did was do what they’ve done since social media became popular…they DARED to report scientific fact, without any inherent political message.  Badlands National Park in South Dakota sent out a series of tweets earlier today, simply providing the facts on what’s happening with our atmosphere and climate change.  Here’s a sampling of their tweets from the day:

National Park Service - Badlands Tweets

Pretty innocuous stuff, and pretty much the same kind of science information that’s tossed out on social media by many federal science agencies.  The response to DARING to state how much carbon dioxide is in the atmosphere? After a few hours, all climate-related tweets on the Badlands site were deleted, without explanation. Was there some violation of federal policy with the release of this mundane, extremely well-known, and well-verified data? As this story from Salon.com notes,the following rule of thumb generally applies to the disclosure of information by federal employees:

A public employee is allowed to speak publicly or share information with the media, if that information is not considered a government secret or classified information.

Evidently stating how much carbon dioxide is in the atmosphere is now a “government secret” or “classified information”.

The public clearly has a right to know how their tax dollars are being spent.  There were several reported cases of the Bush administration editing climate-related research results, changing phrasing or eliminating certain results to downplay the expected impact of climate change. While the Bush administration was openly criticized for their attempts to downplay climate-change impacts, those interventions were in fact relatively infrequent.  Science research in the federal government, including climate-change research, has generally been considered public domain information, and attempts to muzzle or modify research results have been few and far between.

The actions of the Trump administration in just the first 5 days are a warning shot across the bow for scientists in general, a warning that science is now subject to the same vagaries of politics as is the rest of the federal government.

Thousands of Snow Geese Killed in Montana

Snow Goose - Chen caerulescens

A mighty flock of swirling snow geese, looking for a place to land while migrating through South Dakota. It can be pretty spectacular when the geese are migrating through the state, but alas, these birds have to land SOMEWHERE to rest and refuel. A massive flock in Montana made the mistake of landing in a toxic mine pit, resulting in the death of thousands of birds.

I had to travel to Minneapolis yesterday for a work trip.  We’re about a 4-hour drive from the Twin Cities, I HATE flying, and especially given that I’d have to tly, pick up a rental, and then drive 20 miles through town to the north part of the city where my meetings were, I decided I’d drive instead of flying.  Winter has finally hit the area after an incredibly warm and beautiful fall, with 40+ mile-per-hour winds yesterday and plummeting temperatures, but that huge weather change did trigger a massive migration of Snow Geese through the area. As I drove I often saw many very large flocks of Snow Geese, struggling a bit in that wind, but all moving south to escape the cold temperatures.

Around here in South Dakota, you’ll typically find Snow Geese in two types of locations.  During the day, you’ll often see massive flocks sitting in open agricultural fields, feeding on grain residue.  When they’re looking for safety and a place to rest, they’ll choose a lake or other water body.  Imagine a flock of 10,000 Snow Geese, heading south to escape winter.  They’re flying for many hours, are tired and are looking for a place to rest, and upon finally spotting a large patch of open water, they circle and head down and land on surface to rest.

It’s not just South Dakota and Minnesota where the migration has been in full swing. In Montana a flock of many thousands did the same thing this week, circling down to rest in a large water body.  Unfortunately, that open water body was the infamous Berkeley Pit, an EPA Superfund site, and a toxic cesspool of cadmium, copper, zinc, and a host of other dissolved minerals that result in water acidic enough to dissolve metal.  The bodies of thousands of geese were found in the lake this week, chemical burns covering their bodies, as well as the linings of their mouths and throats for birds that tried to drink or feed.  Some birds temporarily escaped the toxic hell, but the bodies of many other Snow Geese have been found scattered throughout the area as they succumbed to the chemical mix after leaving the mine pit.

There are no physical barriers to prevent waterfowl or other wildlife from accessing the toxic water in the mine pit. The story notes the company that owns the mine (Atlantic Richfield Company) uses noise and other deterrents to try to scare away wildlife from accessing the water. The company touts “official” numbers they report to the EPA, that only 14 birds died in the mine pit in the period from 2010 to 2013.  Yeah, sure.  The company may have reported finding 14 carcasses during that span, but I find it very hard to believe that open water didn’t attract more wildlife, deterrents or not, and that intentionally or unintentionally that 14 count is a woeful undercount of the true toll.

Don’t think a company would try to cover up other such incidents?  The Washington Post story notes that a similar, yet smaller scale event happened in the same pit back in 1992.  During that incident, Atlantic Richfield Company tried to pass blame of the birds death to other causes, stating that perhaps “toxic grain” or some other poison killed all the birds that were floating in their mine pit.  That defense fell apart when the University of Wyoming did postmortems on the birds and found their deaths were caused by severe burns, from water acidic enough to dissolve aluminum and other metals.

This is but one incident, in one mining pit.  There are literally thousands of such waste pits in the western U.S., relics of either past or current mining operations.  Very short-term economic gain drives the development of these mining areas, but what about the long-term impacts?  What is done with waste pits like after mining ceases?  Are there any plans to ever detoxify the waters and clean up the mining residue?  Or is this the “norm”, where seemingly the only plan to avoid environmental catastrophe is to make a little noise to try reduce how many animals die in the toxic stew?  This pit was in operation from 1955 to 1982, a 27-year run of productivity, but in the 34 years since mining ceased, what has been done to mitigate the toxic stew that’s been left behind?  It’s an EPA Superfund site, but that designation clearly hasn’t fixed the problem 34 years later.

A mining company profited for 27 years from this pit.  The environmental damage and what’s been left behind will end up taking a toll for a much longer period of time.  We’ve now got a new administration coming into office with an obvious laser-sharp focus on corporate America.  Cabinet appointments to date, stated policies that are being pushed once they take office, a desire to slash regulation and even kill off the EPA…it all typifies that “ME FIRST!”, selfish, greedy, short-term gain mindset that sadly “Trumps” any thought of long-term devastation such as this.  I’ve said it before…I always wonder if people with this kind of mindset have any children, or give a damn about their futures if they do have children.  I can’t ever imagine putting money and short-term well-being over the well-being of future generations.
