fly v. drive (crossposted from Facebook)

Ever since we could afford it, we've always flown to our vacation destinations rather than drive. This is because we take two-week vacations, and I didn't want to spend four days or more simply driving to and from (not to mention recovering from the long driving days).
Recently, I've seen some claims that air travel is far more damaging to the climate than driving. There are other reasons to fly instead of drive (flying is *way* safer), but this certainly got my attention. Turns out, the math is far from clear, especially when you include the externalities of infrastructure to support air vs ground travel:

Two sides

Image
  Yes, there are two sides to every question. In most cases, there is a correct side and a wrong side. In the case of Kamala Harris, the correct side is that she was born a US citizen. The wrong side is that her parents had to be citizens or permanent residents for her to be a citizen. President Trump pretended to be unsure about this, just as he pretended for five years that Barack Obama is not a citizen. In the case of the Harris noncitizen claim, it is backed by the racist C laremont Institute: "The Claremont Institute masquerades as an intellectual salon of the right, but it is really just a racist fever swamp with deep connections to the conspiratorial alt-right. It even granted a fellowship to Jack Posobiec, who helped promote the notorious Pizzagate conspiracy theory. Claremont’s resident bigots offer deranged fantasies of violently expelling Americans from their home country because of their ethnic backgrounds. Their work deserves the intellectual weight given to that of D...

Who chooses?

Over at jabberwocking.com , Kevin Drum blames pro-choice writers for failing to make the case for reproductive choice. Well, from everything I've read, a clear majority of Americans believe that Roe should still stand. Seems like the case has been made, and if we lived in a truly representative democracy, a limited national right to abortion would be preserved. But beyond that reality, I think Drum has it exactly backwards. Why does the burden of proof fall on those advocating for personal autonomy? Seems to me the null hypothesis is that women should be allowed to make decisions about their own health, and that the justification for nanny state intrusion into such decisions rests with the minority who assert state coercion. Democrats need to hammer on the right-wing GOP to explain why the government takes temporary custody of pregnant Americans. https://jabberwocking.com/liberals-really-suck-at-defending-abortion/

Black Earth

 Just finished reading “Black Earth: The Holocaust as history and warning” by Timothy Snyder. It is a detailed account of the Holocaust, as well as an effort to abstract lessons from this history for our time. Like his book “Bloodlands,” Snyder’s “Black Earth” makes for painful reading. As the grandson of a Ukrainian Jew and the son of a Jew, I would have been targeted in the Holocaust had I been in the wrong place. I had read several histories of Europe in World War II that included the Holocaust. I knew the basic story of the Holocaust and Hitler’s anti-Semitic vision. I learned a great deal by reading this book. I won’t belabor the ghoulish atrocities committed by the Nazis and their collaborators. To summarize them here would be to trivialize the enormity of the crimes and invite pointless debate about who did what and who suffered more. You’ll have to read the book to understand Snyder’s historical insights. However, I learned many things that I did not know by reading thi...
