Real Anti-Racism:
It’s not what you thinkPosted in Thoughts
Shaking the hand of someone you disagree with isn’t as much fun as shouting them down, but it is far more effective.
When you live in small groups on the savanna, as our ancestors did for most of our evolutionary history, it pays to be suspicious of strangers. Other groups were competition. Strangers didn’t drop by for a cup of tea and a friendly chat about our emotional well being. We couldn’t afford to see a stranger as a real person at all. It was an “us versus them” world. Fear and aggression were the only rational responses. People who did well in that world (AKA our ancestors, the people from whom we get our DNA), knew that the only safe thing was to beat strangers with a club first and ask questions later.
Fear of “The Other” is hardwired, and talking about it doesn’t help.
We may not live in small groups on the savanna any more, but our brains don’t know that. For better or worse we are stuck with our evolutionary baggage. Nothing is going to change that. When you encounter someone who your brain perceives as “other”– and by this I mean you personally, dear reader, as well as myself and every other human on the planet — all of that machinery jumps to life in milliseconds. Long before we are consciously aware of anything, our brains are screaming “Danger Will Robinson! Danger!”
Call this tribalism. Call it racism. Call it in-group/out-group dynamics. Call it identity politics. Call it polarization. Call it whatever you like. It all comes down to the same thing. When we perceive someone as other our reactions are hard wired, preconscious, and impossible to turn off.
Good intentions don’t matter. Get high and sing Kumbaya all night. Talk about it until the cows come home. Hold workshops. Post platitudes or scream about it on the internet. If you want to judge the effectiveness of those strategies all you have to do is pick up the paper. The louder the mob screams, the more ground they lose. We’ve tried those approaches. They make things worse, not better.
Quoting Einstein’s famous parable, “Insanity is doing the same thing over and over and expecting different results.”
There is only one solution: Humanize yourself by embracing the humanity of others.
If you perceive someone as other you will respond to them as a threat. There’s nothing we can do about that. Or is there? Take a step back and the answer is obvious. We can’t change how we react to other, but we can change who we perceive as other.
There is going on 70 years of really fascinating sociological, psychological, political and even neurological research that all supports the same conclusion: If you know and respect someone, it’s hard not to care about them. Break bread together, laugh together, talk deeply, listen, show respect (even when it’s difficult), build bridges, find common purpose and work arm in arm.
I could dig into that research, but mercifully for you I won’t. Instead I am going to share an uplifting and illustrative story of what effective anti-racism really looks like.
How did a Black musician change the hearts of hundreds of Klansmen?
Daryl Davis is a Black blues and jazz musician with a very strange hobby. He goes to events like KKK rallies not to shout or protest, but to listen, shake hands, talk, and befriend. Literally hundreds of the Klan members who Daryl Davis has become friends with have renounced the Klan. He has a large collection of their robes, including the robe of a man who, when they met, was the Grand Wizard himself.
Read that last sentence again. Then if you honestly care about fighting racism you owe it to yourself to invest 18 minutes and listen to Daryl Davis’s story in his own words.
This is not your Woke friend’s Anti-Racism.
It feels good to gang up and shout at people. The difference between the shouters and the shoutees makes it really easy to tell who is “us” and who is “them.” Our brains love that. The dopamine flows like a river.
But that is not what Daryl Davis did. There was no shouting about racism. Terms like “White privilege” and “White fragility” were never used. Daryl Davis never complained about microaggressions or political correctness. DEI workshops were not part of the program. Mr. Davis did not wear his feelings on his sleeve. Quite the contrary, Daryl Davis listened even to open hatred and tried to understand where it was coming from. There was no talk of victims and oppressors. There were no social media attacks or calls for deplatforming. There was no virtue signaling about Wokeness.
Instead, Daryl Davis treated those who were predisposed to hate him with dignity and respect. He listened. He questioned. He befriended. He humanized himself by seeing and acknowledging the humanity of others, including those with whom he deeply disagreed. In the process he did what few have ever accomplished. Daryl Davis changed the hearts of hundreds of the most committed racists in the nation.
This is what real, effective anti-racism looks like. And as Davis mentions at the end of his talk, if he can do it, so can we.

Schools in the Time of COVID

You don’t tug on Superman’s cape. You don’t spit into the wind. Yes, schools are desperately important to kids. No, COVID-19 doesn’t care, and COVID is making the rules right now. Attempts to open schools this fall will fail of their own accord. The relevant question is how to meet the needs of children, families and the community in the face of that reality.

Watching Rome Burn & Hell Freeze
The fun physics of global cataclysm
What do record fire seasons in the West, record hurricane seasons in the Atlantic, record winter storms in the South and the hottest years in history have to do with each other? Everything.
This article originally appeared in the December 2019 issue of my Astronomy Magazine column, For Your Consideration.
I wrote this piece for Astronomy a bit over a year ago, focusing on the bizarre weather of the previous year. Not to be outdone, 2020 said “hold my beer” and offered up history’s worst fire season in the American West, the busiest Atlantic hurricane season on record, and one of the two hottest years ever seen. Just to add insult to injury, as I prepare to post this 2121 has stepped up to the plate shattering thousands of low temperature records as the worst winter storm in decades sweeps the South.
Heat flows from the tropics to the poles, and Earth’s rotation stirs the pot.
If Earth were the same temperature everywhere, our lives would be pretty boring. Actually, they would be more than boring; they would be impossible. Thank goodness that isn’t the case. Differences in the directness of sunlight at different latitudes and the high albedo of ice as compared to land and open ocean mean that equatorial regions soak up a lot more heat than polar regions. And that thermal gradient is what keeps things interesting.

One effect of global warming is to make extreme excursions in global circulation patterns more likely. The figure shows the slow moving Rossby wave that brought record cold Arctic air into the Continental United States in mid February, 2021. (Colors show surface temperatures. Lines show upper atmospheric flow – jet streams – at pressure of 250 hPa.)
The basics of how temperature differences stir things up are straightforward. Warm air near the equator rises, then at high altitudes spreads out toward the poles. In the meantime at lower altitudes, cooler air moves toward the equator to replace the rising warm air. The opposite happens at the poles. High-altitude air carrying extra thermal energy moves toward the ground, heating things up, while cold ground-level air moves toward lower latitudes. Coriolis effects due to Earth’s rotation break the system into equatorial, midlatitude, and polar convective cells separated by high-altitude jet streams.
Without that global thermal conveyor belt, the poles would be about 45 degrees Fahrenheit (25 degrees Celsius) cooler, and the equator 25 F (15 C) warmer than each is today. This is the engine that drives Earth’s climate and weather.
Global warming makes it easier for Earth’s atmospheric top to wobble.
So, what would happen were the difference between the poles and the equator to lessen for some reason? Needless to say, things would change, but how? Again, the basics aren’t hard to grasp. A fast-spinning top is stable, but as it slows, it wobbles. A hurricane with a very low central pressure has a tight, stable structure. But as the pressure difference between inside and outside the storm weakens, circulation becomes sloppy and unstable.

If you wonder what’s up with Earth’s oceans and atmosphere right now, or at some point in the past, check out the cool visualizations at earth.nullschool.net.
The same thing applies to Earth’s atmosphere as a whole. Just like a hurricane coming apart as the central pressure increases, increasing the temperature of the poles relative to the equator could easily destabilize global circulation. Mucking with that balance isn’t tickling Earth’s climate system. It is kicking it squarely in the posterior.
The thing is, that’s exactly what we’re doing. Atmospheric carbon dioxide and other gases allow visible sunlight in but reflect infrared radiation back into space. Unsurprisingly, thickening Earth’s atmospheric blanket heats things up. But that heating isn’t uniform. The poles are much more affected by greenhouse gases than is the equator. Melting sea ice adds insult to thermal injury.
As expected (and predicted), as global warming has reduced the thermal imbalance between poles and the equator, circulation around the poles has gotten a lot more wobbly. In some places, the northern polar jet steam can go way to the south, bringing cold polar air with it. In other places, it can go way to the north, drawing hot tropical air toward the poles. Those big excursions are called Rossby waves.
If it seems like the weather is getting crazier, that’s because it is.
Common, fast-moving Rossby waves carry storm systems from west to east. But the until recently uncommon, slow-moving Rossby waves I’m talking about are a different beast. These waves get stuck doing what they do in the same spot, sometimes for weeks on end.

On February 26, 2015, Oklahoma Senator Jim Inhofe threw a snowball on the Senate floor to prove that Climate change is a hoax. I suppose that is the kind of thing that happens when an unscrupulous huckster sells his ignorant soul to Exxon-Mobile.
The things that they do are pretty funky, and can get extreme. For example, the polar jet dipped all the way down into Arizona in late spring. Snow fell in Flagstaff, and in Phoenix temperatures 20 F (10 C) below normal had us wondering if it was time to pull our sweaters back out. At the same time, the stalled jet stream pulled humidity from an overly warm Gulf of Mexico and dropped it on the U.S. Plains, turning Oklahoma into a good approximation of an inland sea and blasting it with tornadoes on a daily basis. The show continued as Alaska “enjoyed” air coming up from the tropics, pushing Anchorage above 90 F (32 C) for the first time ever.
Slow-moving Rossby waves are fun in the northern winter, too. Referred to as the “polar vortex,” the masses of polar air Rossby waves bring southward have been pounding the U.S. Northeast with hellish record-breaking winter storms even as Alaskans experience what for them amounts to shirtsleeve weather.
Welcome to the new normal. Why did Nero fiddle while Rome burned? I’m sure it was spectacular to watch, and at that point what else was he supposed to do? So, is it bend-over-and-kiss-your-keister-goodbye time for us? If not, it’s not far off. But hey! At least the physics of climate change is cool.
