Geoengineering Idea

One of my favorite movies of all time was Spaceballs. That’s probably because I was a young boy when I saw it, and have not watched it since. In any case, remember MegaMaid? You can imagine she can serve some very important climate functions. If we could construct carbon scrubbers for our atmosphere that would […]

All of these accept the premise that future damages from anthropogenic warming will be serious, i find this to be a useful discussion strategy: Climate change will cause massive heat and drought and leave people in need of food. OK, compare then, the most effective and optimistic scenarios for reducing CO2 emissions and preventing warming […]

Suppose World Total GDP, which now stands at apx. $70 trillion, grows at about only 2% per year (ignoring population for a moment). This means that over the next 100 years, GDP will double approximately three┬átimes (use the rule of 69.3!). If you think total growth will be 3%, not at all unlikely, it will […]

The effective altruism movement seems to be taking off. It is not at all hard to understand the appeal. Many of us (not me of course, I don’t care) struggle every day with the notion of trying to live a good life and as part of that life we want to have a positive impact […]

Certainly there have been some well publicized surveys over the past couple of years both worldwide and in the US that interest in environmental issues is waning. Certainly on a policy level, when people are asked to rank many environmental issues as compared to health or education or jobs issues, the environmental ones come near […]

Here is a fun conversation-starter at a dinner-party. Ask the person you are talking to what sexual position their parents used in order to conceive them. I am serious. What’s the rub? Well, “transgenic foods” (popularly and incorrectly referred to as Genetically Modified Organisms or GMOs) inspire much trepidation and one of the common arguments […]

Regulate the EPA

This obviously “suits” my preferred narrative. What a shame. By the way, the worst polluter in the U.S. is the Department of Defense, but maybe if we adjust for scale the results would be different. The EPA is not “bad.” No more no less than any other org. Tales as such should not be used […]
