Droughtman is strangely quiet these days. It has been cool and cloudy and is forecast for more of the same, with the possibility of precipitation, and he hasn’t said anything snide about it. It might have something to do with the latest information from our water management people. They have raised the drought level to 3, very dry. Although that would normally trigger Droughtman to sneer at them and point out that there’s still water in the big lakes, they also mentioned that Okanagan Lake, the biggest, is low. His go-to proof that he knows more than they do has let him down, and he has gone quiet. In addition, the upper-elevation reservoirs, which Droughtman had failed to consider in his earlier claims, have failed to fill this year.

All this is giving water utilities cause for concern. Their supplies look as if they might not meet demand, so they are replacing voluntary measures with restrictions on their customers’ use of water. So far it’s just for outdoor use, such as watering lawns and gardens on a strict schedule, but if it continues dry the restrictions will escalate. Already the lakes are low, as are the reservoirs and some wells, and even with the cooler and damper weather recently, we’re well below average for precipitation. It could be that all this information has been enough to quiet even Droughtman.

Time will tell, I guess.

Look up in the sky! Is it a cloud? Is it rain? No, it’s Droughtman! Yes, I’m afraid our blogger is at it again. Our water watchers have raised the advisory level to 2, which stands for dry conditions and the first signs of potential water supply problems. It is the time when some water suppliers might consider asking their customers to begin voluntary water conservation. The snowpack is gone and rainfall is still well below normal, so these are wise precautions. Not for Droughtman, though. To him it’s fear-mongering. Apparently the people we pay to keep watch for us are drought-crazy and they get some kind of mysterious benefit from scaring us unnecessarily.

I think I have gleaned a clue into Droughtman’s thinking now. He points out that the big lakes haven’t dried up. It seems that, to him, as long as we can pump water out of the lakes, there’s no drought. So he defines drought, not by precipitation, but by the availability of water for our use. I guess this means that we could go ten years without rain or snow and, as long as the lakes haven’t dried up, there’s no drought.

He didn’t mention the upper elevation reservoirs, though, where we get much of our water during the dry season. These reservoirs won’t be replenished without rain and snow, but maybe Droughtman would have us fill them by pumping water out of the big lakes.

In my area precipitation has been below normal for the last few months. This is the time of year when we would normally expect a good part of our annual rainfall, and the appropriate authorities have been warning us of the possibility of drought. The conditions are abnormally dry. If they continue abnormally dry then the criteria for moderate or worse drought conditions will be met, hence the warning. That’s what we pay them to do. We pay people to collect the data and we pay other people to interpret it for us so we can plan accordingly.

It’s not a perfect system. It doesn’t always get everything right. Sometimes the actual amounts of precipitation will differ from the forecasts used in their projections. It’s not a perfect system, but it’s the one we use. They have to work with the available data and this year the data is saying that it’s drier than normal. It would be wrong to criticize them for employing current best practises with an abundance of caution.

We’ve had some rain in the last couple of days. We’re still below normal for the period, and there are dry, sunny days in the forecast, but a local blog operator has made a post mocking the reports warning of possible drought conditions. He thinks it’s clever to sieze on two wet days and mock the efforts of the people we pay to watch out for us. This same blogger has used a cold snap in the winter as an opportunity to say, “So much for global warming, eh?”

What are you supposed to do with people like that?


I’ve written about racism before. I think I’ve made it clear that I don’t think science can justify dividing us into “races.” The similarities among us are too great, and the differences within the “races” are also too great. As I have said, if you see races, you’re racist. Here’s a link to an article that covers the subject more thoroughly, including the admission that racists are not idiots. Not all of them, anyway. They know about the science too, and they know how to bend it to support their bias.

Over the last decade, there have been hopes that the US has become a post-racial society, free of racial prejudice and discrimination. However, the most recent months indicate the contrary: race remains an incendiary issue. Race and racism are not new issues, but in today’s 21st century Trump-era, discussions about race are distinct from those of the past in that they possess an entirely new dimension: that of genetics and DNA.

Ancestry test kits are the new “it” item—and with their success is the tacit admission of our belief that our DNA can sort us into categories like the “five races:” African, European, Asian, Oceania, and Native American.

If separate racial or ethnic groups actually existed, we would expect to find “trademark” alleles and other genetic features that are characteristic of a single group but not present in any others. However, the 2002 Stanford study found that only 7.4% of over 4000 alleles were specific to one geographical region. Furthermore, even when region-specific alleles did appear, they only occurred in about 1% of the people from that region—hardly enough to be any kind of trademark.

In the biological and social sciences, the consensus is clear: race is a social construct, not a biological attribute.

… the broader public is not convinced of this. After all, if an Asian person looks so different from a European, how could they not be from distinct groups? Even if most scientists reject the concept of “race” as a biological concept, race exists, undeniably, as a social and political concept.

Despite the scientific consensus that humanity is more alike than unlike, the long history of racism is a somber reminder that throughout human history, a mere 0.1% of variation has been sufficient justification for committing all manner of discriminations and atrocities.

Mounting scientific evidence has shown that humans are fundamentally more similar than different from each other. Nonetheless, racism has persisted. Scientific findings are often ignored, or otherwise actively misinterpreted and misused to further racist agendas of extreme political groups.

If you’re interested in a synopsis of the current state of “race” and the science around it, follow the link to the original article.

How appropriate that right after Laird’s post, On Spiritual Matters, I should come across this Scientific American article discussing belief and disbelief. The author explains how he was initially indoctrinated to believe in a particular theology, found it wanting, explored other avenues and eventually concluded that, rather than finding something he could believe in, he should accept that disbelief is just as valid. Interestingly, at least for me, he included science in the avenues he explored in his search for the answers to his existential questions.

So where does this leave me, in terms of my search for answers? I’ve given up hope that science can give us a single, objectively true solution to the mind-body problem, one true for everyone. Disbelief, I’ve decided, is the only rational stance to take toward alleged solutions, whether religious or scientific.

He understands how this can be unsettling for some people.

Those who yearn for certainty about who we really are might find disbelief unsatisfying, even frightening. You have no ground on which to stand, no assurance that God or science will take care of us, that everything is going to be okay.

But it’s right for him and he thinks it could be right for others as well. It’s a good article. I recommend reading it if these questions have ever occurred to you.
