Discusses his new novel, and the role of science fiction.

He is one of the few authors whose books I always look forward to reading, though I was a little disappointed with Anathem. But this looks like a fun read.

I should also note that one of the points I make in my book (and in op-eds) since, is that our unwillingness to use the hardware we have on hand to get into space is an indicator of how utterly unimportant human spaceflight is (a point that is accentuated by the relatively poor sales of a well-reviewed book). Stephenson describes a scenario in which it suddenly becomes very important to become as spacefaring as possible, as soon as possible, and how society reacts.

Global Cooling

A study predicts decades of it ahead.

Cold is much more deadly than heat, by an order of magnitude.

I have no more confidence in this prediction than I do of predictions for warming (and particularly predictions of catastrophic climate change). The lesson is a) the climate can always be counted on to change, b) we don’t really know what the future holds for climate, c) we need to be prepared for anything, which means maximizing economic growth and d) (related) we need to stop fantasizing that carbon dioxide is a magical climate-control knob.

Cholesterol

Matt Wridley has a brief history of how it’s not bad for you. And this is worth repeating in the context of climate “science”:

If challenged to show evidence for low-cholesterol advice, the medical and scientific profession has tended to argue from authority — by pointing to WHO guidelines or other such official compendia, and say “check the references in there”. But those references lead back to Keys and Framingham and other such dodgy dossiers. Thus does bad science get laundered into dogma. “One of the great commandments of science is ‘Mistrust arguments from authority’,” said Carl Sagan.

Similarly, mistrust people who talk about “consensus” and quote fake statistics on how many scientists believe something.

Yes, obviously the Texas flooding is caused by our SUVs:

For climate scientists like Brenda Ekwurzel of the Union of Concerned Scientists, the link to a warming planet was obvious.

“When you have a warmer atmosphere, then you have the capability to hold more water vapor,” Ekwurzel explained. “When storms organize, there’s much more water you can wring out of the atmosphere compared to the past.”

So I guess that would explain all the recent flooding in California, too.

Oh, wait.
