A Planetary Crisis

On my recent Amtrak trip between Tucson, AZ and Alpine, TX, I caught up on some reading. The highlight of that reading was an article by Alexandra Witze entitled “A Planetary Crisis” in the March 12, 2022 issue of Science News (pp. 16-24). This is absolutely the best article I have ever read about the history of our scientific knowledge on the topic of human-induced climate change.

You can read the print edition of this article, or the version online.

One important point to call out. The Mauna Loa Observatory in Hawaii has been continuously monitoring atmospheric CO2 levels since March 1958, and the annual mean CO2 level has increased 31.8% between 1959 and 2021.

1959315.98 ± 0.12 ppm
2021416.45 ± 0.12 ppm
Annual Mean CO2 at Mauna Loa expressed as a mole fraction of dry air
(micromol/mol = parts per million = ppm)

And, most recently,

May 2021419.13 ppm
May 2022420.99 ppm

Alarmingly, the rate of increase is not linear.

We know that carbon dioxide is a potent greenhouse gas. And, as Witze’s article explains, that fact has been known since 1856.

One thing is crystal clear. Human activity (mostly the burning of fossil fuels) is causing the increase in the atmospheric concentration of carbon dioxide, and that is causing our planet to warm. We need to quickly and substantially reduce the amount of CO2 we are dumping into the atmosphere—or risk catastrophic consequences. I’m trying to do my part. We just installed rooftop solar panels that should generate most or all of the electricity we consume, including that required to power an electric car. As soon as I can get one (this fall?), I will be trading in my gasoline-powered car for an electric one.


By the way, I’ve been a subscriber to Science News for the past 50 years, and in my opinion there is no better newsmagazine covering all areas of science. If you aren’t already a subscriber, please consider becoming one.

Classical Music Exploration Club

You’ve heard of a book club, where people get together to discuss an assigned book that everyone in the group has read. Well, how about a music club? A music club would be a group of people who get together to listen to and discuss music. Unlike a book club, however, it wouldn’t be necessary for the participants to listen to the music prior to meeting.

I’d like to help start a Classical Music Exploration Club here in Tucson. We would need a place to meet that has decent audio equipment. We’d get together, say, once a month, and each month a member of the group would bring a favorite piece of music to share with the group. We’d all listen to the music, perhaps take some notes, and then discuss afterwards. The presenter-of-the-month would certainly have the opportunity to present information about the composer and the work both before and after the work is played.

I’m sure I’m not the only one in Tucson who is bursting at the seams with great music we’d love to share with others. Much of that music will be new and exciting for other members of the group, and that’s the idea. The pieces we’ve heard in live performance and even on the radio is but a small subset of all the great music that is out there, waiting to be heard and to be performed.

If you’d like to help me start a Classical Music Exploration Club here in Tucson (or elsewhere, for that matter), please post a comment here, or email me at doesper@icloud.com.


A little over a year ago, I created an online discussion group to showcase great classical music that is not currently available on CD. It is called Classical Music Little-Known Favorites and is on groups.io.

I realize that there probably aren’t a lot of people who are actively researching little-known works and composers, but it profoundly saddens me that after 15 months, our group only has three members, and I am the only one who has posted anything. Perhaps serious classical music enthusiasts are not familiar with groups.io, or the folks most likely to participate do not reside in the U.S., or they are not fluent in English, or…

Nothing would make me happier right now than to have at least one other person actively participating. Please join, or let others know about it.


A friend of mine recently told me (emphatically) that “Classical music is boring”. I told him that I agree that a lot of it is boring, but that there is so much that isn’t! He probably just hasn’t heard any of the “good stuff”. I grew up in the heady days for popular music in the 1960s and 1970s, and I still love a lot of rock and roll and “pop” music – especially from that era. But for me, popular music took a nosedive starting with the disco craze of the late 1970s, and since then I’ve turned increasingly towards classical music.

As much as I love rock and roll (especially The Beatles), the emotional response that that sort of music evokes in me is different than it is with classical music. When I listen to a great piece of rock music such as the medley at the end of Abbey Road, or Maybe I’m Amazed, it makes me feel happy, motivated, and alive. But only classical music can profoundly move me and bring tears to my eyes.


I’m at the age now where a lot of people I knew and admired in my youth are dying. Often, I’ll read an obituary of someone I worked with or casually knew outside of work, only to discover something fascinating about their background or an interest that we shared, and feeling sad that I never talked with them about x, y, or z.


It is so hard to get to know your neighbors these days. COVID-19 and its numerous variants, partisanship, and (for some of us) working remotely have acted to isolate us even further. Much of our interaction with other humans is of a superficial nature. This seems especially true for older adults. I now live in a large but beautiful gated community. It is obvious that a lot of thought and good planning went into designing it 20 years ago. And yet, we have a community swimming pool but alas no meeting room or common house.


Much to my delight, I now live in a neighborhood where the streets are well-maintained. Riding a bicycle is no longer a bone-jarring experience across “rubblized” pavement, as it was in Dodgeville (Wisconsin) and Alpine (Texas). Our HOA dues here are $43 per month, and much of that money goes towards resurfacing the streets every four years. As far as I’m concerned, it is money well spent. I wonder how many people living in Dodgeville or Alpine would be willing to pay a monthly fee of $43 per month (and probably less) to keep all their city streets in good condition?
