Data on the two carbon cycles: Not even close

on September 5, 2025 in Nature, Visualization

Emissions of greenhouse gases are measured and reported as major indications of environmental problems. Emissions aren’t the relevant measure. They distract us from what is relevant to human well-being. They lead people to say, “I exhale and poop. Life requires pollution,” and conclude action won’t work. To be more precise, they feel like they conclude, they actually just rationalize and justify the preconception they wanted. They miss that fossil fuels’[…] Keep reading →

Another summer without air conditioning. What’s the problem?

on September 4, 2025 in HandsOnPracticalExperience, Nature, Perception

I thought we’d have another day or two hitting 90 F (32 C), but the forecast for the next ten days shows the highest temperature will be 86 F, so I figure it won’t hit 90 again this year. I didn’t use air conditioning in my apartment for another summer. A few nights I woke up sweating in the middle of the night. I didn’t write the number down, but[…] Keep reading →

Why not compare trains to planes

on August 30, 2025 in Addiction, Nature

I joined a group trying to find ways to fly less. One of the themes of the group was to show that “taking the train is just as good as flying.” I found this approach counterproductive. It set flying as the norm and other ways of traveling as alternatives. I think some people saw flying as the best and other ways of traveling as trying to measure up as best[…] Keep reading →

Heirloom tomatoes, a local pear tree, and a local fig tree

on August 29, 2025 in Nature, Visualization

I’ve written and recorded a bunch lately on the peaches and heirloom tomatoes I’ve been eating tons of lately because people don’t take them. Here are those posts: I took a picture of the tomatoes so people could see how some are bruised and the skin broken. Maybe many people would find them unacceptable. In the picture below, the one in the upper left is pretty bruised, but didn’t lose[…] Keep reading →

Does anything tear family and communities apart more than flying?

on August 21, 2025 in Nature

I value family. Extracting fuel and minerals leads to things that tear families apart, like making them refugees, child labor in dangerous mines, people living far from the homes they grew up in, causing people to die young, and more. Valuing family is one of the main reasons I don’t fly. I don’t want to tear families apart. Likewise with communities. I don’t want to fund tearing communities apart. Can[…] Keep reading →

Imagine the density of litter was birds and mammals. That’s what our world was like.

on August 18, 2025 in Nature

I haven’t posted about the book The Once and Future World by podcast guest J. B. MacKinnon lately, but it’s one of the more eye-opening books I’ve found on the environment. He asked, researched, and answered how nature looked before modernity impinged on it. In case you worried, he qualified that nature didn’t exist in a perfect state, let alone a static one. It changed all the time. Still, he[…] Keep reading →

More fresh juicy local peaches and heirloom tomatoes than I can handle, saved from waste by rich and poor alike

on August 11, 2025 in Nature, Perception, Stories

I’ve eaten ten or twelve juicy ripe peaches and about that number of bowls of heirloom tomato gazpacho in the past two days. I got them from volunteering. I brought food that a store was going to throw away. The store produce isn’t as flavorful as the fresh, local produce in season in the height of the summer from farmers markets. Other volunteers bring different things from different places. It[…] Keep reading →

Professions and people NOT to ask how to solve our environmental situation

on August 7, 2025 in Education, Exercises, HandsOnPracticalExperience, Leadership, Nature

I have a PhD in physics, the most advanced degree in the most fundamental science. It was my priority for most of a decade. I loved and still love the field. I believe if you want to understand our situation, you must understand science or at least its findings. I also consider nature among the most beautiful thing to learn about. Scientists found out about our environmental situation. They project[…] Keep reading →

Another Green Revolution?

on July 31, 2025 in Nature

I read an article by podcast guest Elizabeth Kolbert about running out of food. Like nearly everyone, she takes for granted that our population will keep growing and we have to feed them. Like nearly everyone, she figures we have to keep producing more food. She quoted Norman Borlaug’s Nobel acceptance speech. He won the Nobel Prize for the Green Revolution so is a reasonable person to learn from. She[…] Keep reading →
