Providence and Ravens
Until I came north, everything I knew about ravens, I learned in Sunday school. (Okay, in Sunday school and from Edgar Allan Poe.) We had their close cousins, the crows, where I grew up in Minnesota, but I don’t remember ever seeing a raven. According to this map, there should have been some there, but I guess I missed them.
It’d be impossible for a child to grow up in the Yukon and not notice the ravens. They are here and they are not silent.
Northerners tend to have a love-hate relationship with these big black birds. If we don’t lock the lids tight on our garbage cans, the packaging from our food waste will be spread all over the neighbourhood by trash-picking ravens. Can you see that the one in the photo (above left) is carrying a scavenged treasure? Once I saw a raven fly off with a whole package of cheddar cheese from a bag of groceries left in the back of a pickup truck in the supermarket parking lot. I’d like to have heard the conversation in that kitchen when it came time to make the grilled cheese sandwiches for supper.
It’s because ravens seem to relish life that we love them. When it comes to ravens, bird-brained isn’t stupid, and some of that raven brain power is used purely for amusement. Ravens love to swirl and roll in the air currents near the edge of the escarpment rimming town, performing stunt-pilot-worthy aerobatics displays. I have it on good authority that ravens have been seen sliding down snowbanks just for the fun of it. Another favorite pastime is playing “Nonny-nonny-nonny, you can’t catch me!” with my dog. Frankly, in an I.Q. competition between my dog and a raven, I’m not sure my dog would come out on top.
Their extreme cleverness shows itself in their hoarding behaviour. Sometimes ravens will store bits of stolen food in little caches so they can come back for it later, and studies have shown that they find their stockpiles again because they remember where they put them. They also spy on other ravens to see where they are burying their goodies, so that when the opportunity arises, the neighbour’s stash can be raided. Sometimes a hoarding raven will only pretend to bury food in order to throw the thieving spies and raiders off the trail. You might say that ravens are the greedy geniuses of the bird world.
But let’s get back to what I learned about ravens in Sunday school, way before any real-life raven encounters. I learned, first of all, that it is God who feeds them.
Who provides for the raven its prey,
when its young ones cry to God for help,
and wander about for lack of food? (Job 38:41)
That’s a rhetorical question and we’re supposed to answer, “God does.” If you need further confirmation, see Psalm 147:9 and Luke 12:24.
God intentionally provides prey and other goodies for the ravens. Yes, they dumpster dive and trash pick and forage for berries and scavenge for carrion and hunt small rodents. They even eat carcass-feeding maggots and beetles. (How’s that for opportunistic snacking?) And this is how God feeds them.
According to Wikipedia, the raven’s “diet may vary widely with location, season and serendipity,” which my dictionary defines as “the occurrence or development of events by chance in a happy or beneficial way.” It’s not quite serendipity, of course, if God feeds them, is it? But if we changed “by chance” to “by God’s intent” in that definition, we’d have a fairly good definition of providence. God intentionally controls the occurrence and development of events with a happy and beneficial result for the ravens.
So by providence, it is, that the ravens are fed. I leave the lid on my garbage can unfastened and it is God’s provision for them. The unguarded bag of groceries in the back of the pick up? Providence for the birds. Road kill? God’s good gift to the hungry young ones. Ravens have enough brain power to devise clever schemes for keeping their food finds all to themselves. This, as well, is God’s providence for them. All these things are good gifts from God who feeds the ravens.
Now Elijah the Tishbite, of Tishbe in Gilead, said to Ahab, “As the Lord, the God of Israel, lives, before whom I stand, there shall be neither dew nor rain these years, except by my word.” 2 And the word of the Lord came to him: 3 “Depart from here and turn eastward and hide yourself by the brook Cherith, which is east of the Jordan. 4 You shall drink from the brook, and I have commanded the ravens to feed you there.” 5 So he went and did according to the word of the Lord. He went and lived by the brook Cherith that is east of the Jordan. 6 And the ravens brought him bread and meat in the morning, and bread and meat in the evening, and he drank from the brook. (1 Kings 17:1-6)

For Your Weather Amusement

Wait, there’s more….
And still more….
If you view this web cam in the morning, you might see ice fog.
The Year With No Summer

When I was a child I read a novel that mentioned a year in the 1800s when there was no summer. I read a book a day at that time and they all blend together, so you can’t expect me to remember a title. What I’ve never forgotten, however, is that there really was a year without a summer.
I imagined a year with snow cover all year round, when people ice skated on frozen lakes in July. That wasn’t exactly the way it was, but 1816 was an unusual weather year. There was a snowstorm that dumped 4 inches of snow in New England in the middle of June, and there was frost overnight for several days in a row in both July and August. In between those extraordinary occurrences, there was fairly normal summer weather, but the frosts caused crop failure in the northeastern US and eastern Canada.
In Europe, there was almost constant cold, wet gloom, and crop failures, too. In Ireland, it rained for 142 of the summer days, causing a famine. There was no grape harvest in France and no grain harvest in Germany.
Historians blame the eruption of the Tambora volcano in Indonesia the year before. It was the biggest eruption in recorded history, and all those ash particles in the atmosphere of the northern hemisphere were bound to cause big changes in the weather.
Not everything was bad. There were brilliantly colourful sunrises and sunsets, which some say inspired the intense glowing depictions of the sun on the horizon in the paintings of the British impressionist painter J.M.W. Turner. You see an example in Turner’s painting of Flint Castle above, and another in one of his nautical paintings, The Fighting Téméraire tugged to her last Berth to be broken up.
According to oral tradition, here in the Yukon there was a year in the 1800s with no summer, when people starved, too. In the 1970s, it was described by Yukon elder Rachel Dawson as occurring over one hundred years previous to her time.
Two winters joined together. No snow, but there was ice all over, and the winters were joined together.
There are variations to the story, and it’s impossible to pin down exactly when it was. Perhaps it was 1816, when the Tambora volcano wreaked widespread havoc, or maybe it was either 1845, 1849, or 1850, when tree ring measurement shows very little growth.
But it all goes to show that in the weather realm, strange things can happen anywhere and anytime.
What I’m waiting for is the year with no winter. Of course, if that happened, they’d probably chalk it up, rightly or wrongly, to global warming, wouldn’t they?
A Little Frosty

I haven’t reported much on the weather here, because even though it’s coldish,
it’s also almost exactly average.
But at least the dreary low clouds have gone, so it’s nice and bright. And it’s not -40.
If you want your post included in tomorrow’s initial collection of weather related posts from around the world and close to home, send me the link 8:00AM PST tomorrow (January 8). If you’ve already sent me your link, thank you.
Bloggy New Year's Resolutions
I did a year end blog review yesterday and that led me to make two resolutions concerning this blog in 2008.
- I’m going to do more just for fun posts. I used to do more lighthearted pieces, but somewhere during last year I got a little too earnest, I think. So expect a little more fluff in the future.
- The second resolution should help me keep the first. I’m going to restore the monthly themes and invite you to participate in them. Last year only January, February, March and November had themes. I stopped doing the themed months because they are so much work. But they are also a whole lot of fun and I miss that. I’ve decided to give them another go, but cut back on how many themed posts I do during each month. Instead of doing them daily, I’ll do a couple a week.
Bundles of Energy
Scientist have possibly confirmed what they’d previously suspected about the energy source for the Aurora Borealis (aka the Northern Lights). All they need is one more geomagnetic storm and they’ll know for sure.
New data from NASA’s Themis mission, a quintet of satellites launched this winter, found the energy comes from a stream of charged particles from the sun flowing like a current through twisted bundles of magnetic fields connecting Earth’s upper atmosphere to the sun.
The energy is then abruptly released in the form of a shimmering display of lights, said principal investigator Vassilis Angelopoulos of the University of California at Los Angeles. (Source from CNN.com)
Like a 5.5 magnitude earthquake travelling four hundred miles a minute, those Aurora producing geomagnetic storms.
“Nature,” says Angelopoulous, “has been very kind to us.” Because, you know, we don’t deserve such a shimmering display of beauty and power, but nature loved us anyway and sent us northern lights. For the beauty of the earth, nature, we thank thee.
