Hot and Cold Running Evolution

I’m not following the primary journals as much as I used to, so this pop-science article in Quanta on the rate of evolution caught my attention.  It claims, apparently on the grounds of several different lines of evidence, that rates of mutation and evolution appear to run faster at short time scales than long time scales.  In other words, there’s more genetic and morphological variation over short time spans than over long ones.

Paradoxical?  Not quite. Useful?  Very. Continue reading



Hot Earth Dreams and Space Opera

I was going to post this on Charlie Stross’ Antipope, where there’s another interesting discussion developing on space opera.  So as not to chunk 1,450-plus words onto that message board, I thought I’d post my thoughts over here, for those who are interested.

The Day After

Yay, it’s the day after Earth Day.  They’ve started signing the Paris climate accord, John Kerry photo-opping by signing with his granddaughter on his lap.  Obama will ratify it by executive action, the Senate Republicans will pass something nauseating telling him to stop chasing myths (unless maybe that doesn’t happen?), he’ll veto their attempt to quash him, and…

Well, what happens next?  In the real world, I’m not so sure, but after I finish the swarm of stuff I’m working on (I won’t be blogging for the next few weeks), I’ll start figuring out how to revise Hot Earth Dreams. There’s still time to get your comments in, but the window is closing.

Now that it’s the day after Earth Day, what have I learned?

California in the High Altithermal Part 9: Death Valley Dreams

Over the last few weeks, I’ve been reading articles (such as this one) about how anomalously warm Alaska and other parts of the Arctic were this winter.  Someone even said that if California had warmed half as much as the Arctic did, we’d be in trouble.

Well, we did warm about half as much.  By my calculations, San Diego was 9°F/5°C warmer than average for the month of February.  This turned what is normally our wettest month into a dry month, with tumbleweeds sprouting in February instead of June, and flowers blooming months early.  The heat squelched our El Niño rains, with persistent high pressure forcing the rains north to flood northern California and Oregon.  Since I’m not a climatologist, I can’t say authoritatively that this is the new normal, but given the fossil record of rain forests in Oregon and the models of a hot dry So Cal, I’ll go out on a little bitty limb and say it sure could be.  But I’m not sure whether we know that we’re in trouble yet.

Still, some rain did get through, so my wife and I took a three day weekend to go up to Death Valley and see the tail end of the “superbloom,” and all I got was this lousy blog idea.  Actually, I had fun and got a lot of cool pictures of individual flowers and landscapes as well, but the massive fields of flowers have faded away.

California in the High Altithermal, Part 8: This time it’s different…

This idea seems to be sprouting like a weed in some odd places, including (reportedly) with a group of professors at UC Davis.  The general idea, as I’m hearing it second and third-hand, is a conglomeration of “this time it’s different,” “weeds are the new natives, you stupid nativists,” and “It’s now the Anthropocene, so the old rules are out the window.”

Just another quick entry with two bits of news, one about Hot Earth Dreams, one about carbon production peaking (???) in 2015.

California in the High Altithermal, Part 7: The Mish-Mash and the Rebirth (?) of Civilization

This is an ongoing series.  Here are links for Part 1, Part 2, Part 3, Part 4, Part 5, and Part 6.

One of the things that’s hard about talking about California’s future is that, on the one hand, I’d love to predict winners and losers, and I suspect others would be happier if I did.  For example, perhaps the Latinos take over.  Or possibly the white ranchers will become the feudal lords of the 24th Century.  Or the permaculturalists will agroforest the north, and the Rainbow Family will become a model for future communities.  Or the resurgent Indian tribes will reassert their ancient hunting and gathering life-styles, aided and abetted by the native plant enthusiasts who help them rewild the hills. Or Guatemalan migrant farm laborers will teach the people of California how to make milpas to take advantage of the increasingly tropical climate, and we’ll all go Mayan or Aztec or Tarahumaran or some such, and grow coffee under the trees instead of pot.  Or the tech tycoons will build their shining arcologies on the hills, beacons of sustainable civilization midst a howling wilderness populated by scattered bands of survivalists.

And I could make a story for each of these. But are any of them stories worth telling because it might be true? Or are they just my biases and preconceptions playing out?
