Check Your Facts

Several years ago, I got an idea for a science fiction short story. It involved the young captain of a ‘worn-out’ asteroid mining ship who found herself pregnant. Such a thing is hardly novel on Earth, but I had the idea stuck in my head - with no idea where I had gotten it - that it wasn’t possible to get pregnant in space. The entire crew is left wondering, “How did that happen?”
Not terribly original, I suppose, but I hoped I was treating the story ‘differently’ from everybody else who had ever written a ‘mystery pregnancy’ story.
So I took the story to my writing group, where everybody told me that of course, she got pregnant; nobody was using birth control, and there’s no reason why people can’t get pregnant in space.
Bummer. That was one of the things that convinced me that my science knowledge was out of date, where-upon I subscribed to and started reading various science magazines, trying to do some catch-up. Until a week ago, I had tried to shove that space pregnancy story out my mind, figuring it had taught me a lesson; Check your ‘facts’.
I was wrong. But not in the way I thought.
Imagine my surprise when I came to an article in the May/June 2019 issue of Discover about how scientists are studying the problem of human reproduction in places that are not on Earth. The problem being that it doesn’t seem possible. Which would make colonies hard to sustain.
As I remember it, they started with lizards and amphibians, which they took to the space station for a period of time. Those didn’t seem bothered by the lack of gravity, or the increased radiation, but some of their off-spring weren’t right.
Then they tried the same experiment with mice, who are mammals, and - biologically - quite a bit like humans. (That’s a lovely thought, isn’t it?) Strangely, the mice must have been freaked out by the no-g or the radiation, or something, but they were not nearly as interested in sex as mice usually are. And even when they did indulge in sex, they didn’t have any offspring.
Apparently, there is a piece of the female mouse’s sexual organs that rapidly decreases and then completely disappears while the mouse is in space. If the same thing happens to human females, then Earth would be the only place where we can make more humans.
Now, that’s a Bummer. But... I was right! (To a degree.) If technology provides a method of humans to begat humans, but only in places that more or less replicate conditions on Earth, then the first human baby conceived without those conditions would indeed be a shock. Not only for the parents, but for the entire race. And that’s the kind of shock I was trying to portray.
So, yes, you should check your facts that you are putting in your stories. And even if everybody in your writer’s group says your fact is wrong, maybe you should check their facts, too.

Hallucigenia

I have started a new list of subjects to research and possibly write a blog about. I get these ideas from on-line and magazine articles that I read; sometimes I jot down the article subject, or a phrase, or just a word I’m not familiar with.Hallucigenia is one of those last ones. If I had realized how many MORE words I would have to look up just to make sense of the wikipedia article on this extinct animal...However, I’m trying to expand my science knowledge, so let’s get on with this.Hallucigenia is a genus of lobopodian worms from the Cambrian period, which lasted from about 541 million years ago to 485 million years ago. The Cambrian period is known for its explosion of new creatures, as nature explored all the different variations it could think of.Hallucigenia was discovered as articulated fossils in shale-type deposits in Canada and China, and isolated spines have been found around the world. Even so, trying to reconstruct what they looked like was difficult. In fact, the first attempt showed the creature upside down and said the front was the back.I probably would have made the same mistakes. First of all, these creatures were only 3/16 to 1-3/8 inch long. It kind of amazes me that anybody even noticed them. To try and imagine what they looked like, start with a worm about that long. Put 7 or 8 pairs of short, flexible appendages down the length of it. Now, flip it over, and put pairs of longer, stiff appendages down the other side of it. The ‘head’ and ‘tail’ are pretty much identical. Which appendages are the legs?The first reconstruction attempt placed the pairs of stiff appendages as the feet because half the flexible appendages were still hidden in dirt. But once the other flexible appendages were discovered, it made sense to put them on the bottom. Flexible legs are easier to use, and stiff ‘spines’ offer some protection.And, by the way, each foot ends with a claw.I found no information on whether these were marine or land creatures, what they ate, what might have eaten them... Now that I’ve researched these creatures, how could I possibly use this information? I suppose I could have a bare-footed colonist step on one, and strange chemicals from the creature are introduced through the spines now buried deep in the colonist’s foot? Or maybe on another planet, these creatures got larger and became the dominant, intelligent species? That might be interesting. How would you incorporate them?

Never Enough Time

I’ve retired from my day job. I should have plenty of time to do whatever I want, right?So, how come I don’t?I think back to when I was working, feeding the family and trying to hold the house together. I managed it. My house didn’t look like any you see in a magazine, because there were always things that hadn’t been put away, and dust accumulated far faster than I could wipe it away. But there was food, usually hot for supper, and I tried to keep the dirty dishes from piling up too deep in the kitchen sink.In the evenings, I almost always multi-tasked by writing while watching tv. Which is not easy to do; you either miss what’s going on in the tv show because you’re concentrating on the story you’re writing, or you stop writing to follow the tv show. Knitting while watching tv is much easier, as long as the pattern isn’t too difficult. Sometimes, I did that.On weekends, I ran errands and cleaned house. Seemed like I never had enough time to get everything done.I don’t work 40 hours a week at a job anymore. I don’t have to spend 45 minutes driving to work every morning and 30 minutes driving home (don’t ask me, it must have been the traffic flow), or ride a bus for an hour each way every day. I should have plenty of time!Hmm. Yeah. Guess what. I don’t.The thing is, I dusted off a few hobbies I used to do long ago, added a couple hobbies I never had done before, and... the days are not long enough!It doesn’t help that the errands have multiplied as well. Because I have diabetes, the doctor wants to see me every 6 months to see how I’m doing. To see how I’m doing, he has to have some lab work done. In Omaha, the lab was in the doctor’s office, so both could be done at the same time. Here in Florida, the medical labs are separate from the doctor’s office, so that’s 2 trips every half year. I have to see a cardiologist, who is not in the same building. I have to see an eye doctor twice a year. And because I’ve had kidney stones (thanks to the mineral-laden water one drinks in Florida), I’ve been seeing a urologist every 3-4 months.Because I suffer from depression, I visit with a counselor once a week, and see a medications monitor once a month.Not enough errands for you yet? I go to pick up prescriptions 3-4 times a month. Yeah, I’d get them all ‘synchronized’, except it seems like every couple of months, one of them gets changed. My husband has his prescriptions ‘synchronized’, but every single month, at least one of his ‘hasn’t come in yet.’ Why don’t they know they need to order it a day or 2 earlier so he doesn’t have to make a 2nd (or 3rd) trip?And because I have diabetes, I’m supposed to exercise 30 minutes a day, 6 days a week.My tiny business needs tending.The bills need to be paid, which requires moving money around between credit unions.The HOA insists we keep the lawn and landscaping in good shape.The dog wants some attention.The house still needs to be picked up and chores done from time to time. Thankfully, my husband does quite a bit of this.I have one day a week assigned for each of my ‘major’ hobbies. (Sunday is my ‘clean office’ day, which is a never-ending battle in and of itself.) Most weeks, I find very little time to devote to hobbies. I try not to beat myself up over that, but... it does get to me.Of course, it might help if I could get my body straightened out enough that I don’t sleep 12 hours a day. Or take 2-3 hours to ‘wake up’ after I do get up.Well, now I’m just dreaming!

Bring the Green!

Have you read the ‘Green New Deal resolution that’s been introduced in both houses of Congress? Nope, me neither. First, I wouldn’t have any idea where to find it. Second, if I did find it, I fear it would be written in ‘Congress-ese’, which I expect is nigh on impossible for laypeople to understand.But I was fairly certain it did NOT say we had to get rid of cows, as one news anchor claimed.So, when I ran across an article that attempted to explain exactly what was included in this resolution (not a bill, a resolution), I took the time to read that.It makes great sense to me. I agree with it completely. Basically, it states that since climate change is not only real but already effecting the population of the US, costing us time, money and even heath dangers, that it is the responsibility of the administration to do everything it can to assist and encourage changes to infrastructure, social norms, and a whole host of other things to help all of us deal with those climate changes. Nowhere in it does it even mention cows.What kind of assistance could the government provide? Where do I begin?We started looking at installing solar panels on our roof decades ago. But at that time, they weren’t very effective and lasted about 10 years, so by the time they ‘paid for themselves’, you needed to replace them. Plus, we were in the midwest, where there were NO companies who offered solar panels or knew how to install them. We got solar panels installed on our roof within a year of moving to Florida. But we still had to take out a loan to do it, and we may never get any of the cost ‘returned’ to us by the government, because we don’t have enough income.Here’s the first few ideas I have on how the government could ‘encourage’ this change to our infrastructure (moving our electricity needs to solar panels and/or windmills): Make arrangements for homeowners to get loans for solar panels (windmills) at a really low interest rate. Encourage (or require) power companies to start replacing their fossil-fuel-powered power plants with solar panels/windmills and batteries. Why not encourage businesses to install solar panels/windmills on their roofs? Or the side of their building? There have been some wonderful innovations in solar panels; I understand one guy even figured out how to embed solar ‘panels’ in roads, so... why aren’t we taking advantage of these things?We’d like to get an electric car, but they aren’t any good if you plan to drive more than an hour or 2. And it’s not like you can pull into any gas station and ‘fill up’ when your battery gets low. When I first started looking at electric cars, it seemed you could drive for 4 hours, then you had to stop and ‘recharge’ for about 8 hours. Assuming you could find a place to do that. About 3 years ago, I heard that ‘high-speed recharging’ only took 45 minutes, but while the Kansas City area had nearly a dozen ‘stations’ where you could recharge, it only had 1 place where you could recharge quickly. Some of the theme parks in Florida offer recharging stations in their parking lots, but I don’t know if you pay extra to get one of those, or how long it takes there.Why aren’t gas stations hedging their bets by installing recharging stations? Investment in solar panels/windmills, a couple large batteries and the recharging equipment could make road trips so much easier for those trying to help save the world. Motels could offer to recharge your car while you catch some zzs. Rest areas could also offer a recharge while your kids and pets are running off their pent-up energy and the family has a snack.How many people would be buying an electric car if they knew they could get it charged up while they were out and about, rather than ONLY in their garage? Parking meters could become charging stations, so that you could fill up while you shop. Why not put solar panels and (tiny) windmills on a car, to help it go another mile or 2 down the road before you have to recharge?There are lots of ways to help ‘encourage and assist’ efforts to save the world, and by extension, ourselves. We just need to stop thinking things like, “That isn’t how it’s done.”

What is This World Coming to? 7

And we are back to water. It seems only fitting, since the globe is mostly covered by it.
As I was looking over information on Central America, one of my hard-copy magazines - Popular Science - had an entire issue on water. Including an article on the sudden and sustained lackof water in Colombia in the northern part of South America.
The northern part of South America is also definitely in the tropics, because that area straddles the Equator, and the tropics is generally 30° north to 30° south of the equator. That’s latitude degrees, not temperature degrees.
Colombia is also quite mountainous, but that doesn’t mean their water supply is assured. The article spoke of one city sitting in the heights below a ski resort. Until recently, that resort could exist because of a glacier that sat atop the mountain. That glacier also was the source of the water used by the city.
Guess what. That glacier is gone now. Not just receding, like so many glaciers are, it is GONE.
No more skiing on that mountain, no more water for that city. Now the water officials load up what water is available into tank trucks and deliver it around the area. When the truck pulls up and stops, everybody runs for whatever they have that will hold water; pots, barrels, bottles and jars. They may go home and empty those items into their sinks or bathtub and run back to see if the truck is still there. If it is, they fill their pots, barrels and jars again.
They don’t know how long it will be before the truck arrives to deliver more water, so they have to be stingy with every drop. It is all they have for cooking and possibly a sponge bath. In the meantime, they listen for notices from the government as to when the water in their taps may be turned on for a limited time.
At one point, the author was with a woman who had stayed home from work that afternoon. The water was supposed to be turned on in the pipes for 3 hours, and she wanted to get some laundry done. But the water never came from her pipes that afternoon. No laundry got done.
Did all the women in the city stay home that afternoon, hoping to get some laundry done?
The article ended with a brief mention of another Colombian city on another mountain, also depending on the mountain-top glacier for its water supply. That glacier is visibly shrunken, smaller than anybody has ever seen it before.
Perhaps they’ll figure out another source for water. The article didn’t mention any attempts to look, to figure something out. Everybody - even the water officials - just kept saying, “The rains will come.”
What are we, ostriches? Refusing to acknowledge a problem will not make it magically go away!
This is a depressing subject, and not the type I would usually spend time on trying to spin into an entertaining novel. I suffer from chronic depression and just found an anti-depressant that actually works for me. I don’t know if I’m done researching this subject or not... my constant companion - depression - keeps telling me to stick my head in the sand and think of pretty things. But the story for the novel is beginning to take shape in my head. I think I’ll start thinking out scenes and where they would go, and speak of other things in this blog for a while. If I need to, I can still do more research.
So, next time, the subject will be... Oh, who knows? Whatever I find interesting between now and then.

Food. We all need it. We all have our favorites. But what will be available for us to eat in the coming much-warmer world?
Like the topic of ‘climate change’, this sub-topic is just as broad a question and just as difficult to sort out.
My initial belief was that the tropics would probably become pretty uninhabitable. After all, at least one city in the Middle East has already come too-d****d-close to that with a temperature of 115°F with 50% humidity. Places that are NOT deserts could be even worse. Deserts at least cool off at night, because they don’t have any cloud cover to hold the heat in. But when the humidity rises, cloudiness increases, so that heat could be held close to the ground. Also, when humidity rises, that ‘drop-dead’ temperature is lowered. At least as low as 96°F.
But the more I’ve researched, the less sure I am of that. I recently spent a few days looking at the countries in Central America, because I figured they were definitely in the ‘heavily tropical’ part of the world. The thing is, Central America is pretty mountainous, so a lot of the land is actually ‘temperate’. The low-lying jungle might not be a place people would want to live, but the highlands could still be habitable.
Crops, on the other hand, might not like the new weather patterns that could come. Even without the global temperature rising, people living in those countries right now have trouble providing food for their families year after year. The rainy season and hurricanes can produce mud slides and flooding. If that doesn’t happen, they could lose their crops because of drought, like the one they’ve been suffering through the last few years.
Anthropologists believe the Mayan civilization crashed because of a severe drought. Now that area is facing another drought, and who knows how bad it will become? None of the articles I read mentioned wild fires like we’ve had in the western states, but will there come a time when Central American starts to burn?
These were my thoughts as I studied this particular area, looking for food crops that might not survive where they have been thriving and will need to be transplanted elsewhere. I don’t have any answers on that yet. The export crops grown here might be okay, as long as they can get enough water. I’ll have to research individual crops - for instance, bananas - in order to take a guess on their prognosis.
Still more to come!

Okay, I did find something to say on this subject, from a totally unexpected source. I was watching an episode on Nova the other night. Our local channel has 2 episodes on Wednesdays, and we usually watch the first, but not the second, because that’s getting too late for my husband, who is an early bird. That night, I heard that the 2nd episode was on Neanderthals, and human evolution has always been an interest of mine, so I stayed up to watch it.
As a whole, the episode explored a lot of different information about the humans known as Neanderthals, but my interest picked up during their talk about the small colony of Neanderthals who lived in caves currently located at the base of the Rock of Gibraltar.
One question this episode was asking is, “Did Modern Humans have any part in eliminating the Neanderthals?” They didn’t have an answer to that question, in the end. Not a simple one, anyway.
Neanderthals lived in the Middle East, Western Asia and Europe for as much as 700,000 years. During all of that time, the world was in an ice age, but the Neanderthals were built for it, and apparently did not find that a hardship.
About 100,000 years ago (maybe as early as 125,000 years ago), modern humans started to populate these same areas. The cold probably made them wear more clothes than the Neanderthals. And maybe there were instances of violence between the 2 sub-species.
However, the scientists said, it was unlikely the modern humans had traveled all the way around the Mediterranean Sea and got to the Rock of Gibraltar before that particular group of Neanderthals died out. What the scientists discovered in those caves showed that the Neanderthals living there not only hunted and gathered, they ate a variety of sea life as well, from seals to clams. Today, the mouths of those caves are practically at the sea line, but during the brunt of the ice age, the water line would have been about 59 feet (18 meters) lower.
Neanderthals lived in small groups. Scientists estimate their entire population may have been about 100,000, scattered in small groups across a quarter of the world. (How big is the town you live in?) And as they studied this particular group, they realized that it died out during a long and severe drought that hit the area.
My thought? Neanderthals were suited for cold. Not so much for heat. They had a short, stocky build that would help them retain body heat. But when the world heats up, that doesn’t do you much good.
If the world were going through the gradual changes of leaving the ice age, the flora and fauna would no doubt evolve in order to survive. But the current rapid pace of warming that we are in doesn’t leave us time for that. Those who currently live in the tropics might manage by migrating north or south to the temperate zones. Those in the temperate zones might find some comfort in the polar regions, although there’s not a lot of land for them to settle on. Once Antarctica thaws, that land would be available. Would it be fertile? Who knows?
It won’t be a matter of the fit being able to survive. Those who can accept what’s happening and deal with it will have a chance to survive.
And I’m back to looking for potential food for that migrating population.

Okay, we’ve spent quite a bit of time exploring melting ice and (some of) the resulting changes to The Oceans As We Know Them. And last time, we touched on the Arctic jet stream, which brings us to the atmosphere. Let’s go ahead and explore (some of) the changes we can expect there.
I just heard on the news tonight that Hurricane Willa - born in the Eastern Pacific Ocean - will tear across the middle of Mexico (despite the mountains) and then hit the south and south-eastern areas of the US. It’s not expected to be a hurricane by the time it gets to the US, but I don’t remember hearing about any Pacific hurricane/cyclone/typhoon doing that before. And anytime hurricanes get mentioned anymore, there always seems to be a cat 5 hurricane that somebody is watching. Some of them have been so strong a cat 5, there has been talk of defining what would make a cat 6.
The average global temperature has risen 1.4° Fahrenheit (0.8° C) over the past 100 years. Now, that’s not 1.4° F for every single location on the globe. Temperatures at the poles have risen faster than other places. But that is a big change over a short period of time, when you are talking about the life of a planet.
Consider the northern plains of China, home to 400,000,000 people, and the place where much of China’s food is grown. It doesn’t get a lot of rainfall, when compared to southern China, so the fields are irrigated during the growing season. Research from MIT indicates that the temperature in this area of China will cross above 95°F several times between 2070 and 2100. At that temperature and with the added humidity caused by irrigation, even young and healthy humans would reach the point where their bodies could not cool off, and death would result within a few hours. And that’s the young and healthy. Old and frail wouldn’t last that long. Do you suppose they’ll farm at night? How would the plants they try to grow fare in that kind of heat?
Shanghai, on China’s central coast, would cross that 95° F threshold about 5 times, and approach it over 100 times during that same time period.
In the Middle East, many areas, especially coastal cities, are in the same mess. In 2015, Bandar Mahshahr in Iran almost reached that ‘death threshold’ when the temperature hit 114.5° F with 50% humidity. Only 50% humidity! But when the temperature gets high enough, the human body can’t function.
What else can we expect? Some areas, like northeast US, may experience an increase in rainfall, while in the northwest US, rainfall will decrease. Washington has been experiencing range fires the last few years, but I don’t remember hearing about them before that. Maybe I wasn’t listening. But I do know that California has been in a drought for several years, and they’ve had fires rampaging across the countryside.
Not a pretty thought, looking at the future and what climate change will do to us. I have a lot of thoughts to piece together for that book I’m thinking about.
I’ll be looking for information about what food will be able to be grown where in the next 50 years. If I find anything interesting on that front - or some other front I haven’t thought of - I’ll continue this series. Otherwise, I’ll wrap this up next time.

So, what else is the Beaufort Gyre (which, you’ll remember, is north of Alaska) doing to The World As We Know It?
Well, it’s messing up the Arctic jet stream. Being from the midwest US, I’ve heard plenty of winter weather forecasts talking about the Arctic jet stream dipping below the Canadian border and bringing truly frigid blasts to the North American plains. Since I still have friends and family living in that region, I pay attention to the winter weather that happens there. Last year was particularly brutal, with that jet stream going much further south than I remember it doing in the past. It wasn’t just the northern states like the Dakotas, Michigan and maybe Nebraska hunkering down against Arctic-type temperatures, they were reaching into Kansas, Missouri, Illinois, Indiana...
How can that possibly mean the climate is warming? Let me remind you that climate and weather are not the same thing. Weather happens on a much smaller scale than climate. As for that Arctic jet stream coming south before returning north, that air gets (relatively) warmed up. Coming so far south, it gets a lot warmer than it normally does, so when it does go north again, it transfers the warmth it gathered to the area it goes; the arctic. More melting.
Earth’s polar ice caps serve a purpose; sunlight is reflected from their white surface, so they act as a ‘cooling’ agent for the entire globe. The more this ice melts and reveals darker-colored water and land, the less cooling is available for the entire planet. Get it? The more snow and ice melts, the more likely more snow and ice will melt. Until there is no more snow and ice to help keep Earth’s temperature moderated.
The really scary part is what happens to the land when all that snow and ice melts. If Greenland’s ice cap melts, the sea level would rise by 20 feet (6.1 m). At its current rate of melt, the Arctic Ocean could be completely ice free by 2040. That’s only 22 years! If all the ice of Antarctica melted, the seas would rise by 200 ft (61 m).
With a sea level rise of only 6 feet (1.8 m), most large cities would be flooded. So, where do you live? I currently live in the center of the Florida peninsula, which would still be here after 6 feet of sea level rise... but loooooong gone by the time all the ice melts. Maybe I should start cleaning out stuff I won’t be needing in my old age, so that it’ll be easier to move north, once that becomes necessary.
By then, New Orleans would be a bay reaching almost as far north as the Missouri boot. The Netherlands would be entirely below sea level, but much of it is now. Hope they have plans for building new, much taller dykes. Australia will be a doughnut, with land surrounding an inland sea. The Amazon rainforest will become the Amazon Sea, and Buenos Aires in Argentina will mean a huge bay. Those are the easy things to notice on the map.
At one time, I found an interactive map showing what parts of the world would be underwater, and the results would change depending on how much you chose to raise the sea level. It didn’t seem too alarming, but I think it only allowed you to raise the sea level by 9 meters.
Alas, I neglected to bookmark that page. When I went looking for it to link to this blog, I found lots and lots of pages with ‘interactive global sea level rise maps’. That means more and more scientists (and others) have been looking at this scenario seriously, and taking the possible sea level rise much higher. Much more ice than that covering Greenland has been and is and will melt, so 9 meters could just be a drop in the bucket.
Water isn’t the only thing that will change. Next time, I’ll examine something else from my research about climate change.

What is This World Coming to 2?

Okay, we were talking about the sea and what climate change is doing to it. My examples last time were in Europe and the US, in the northern temperate zones. Now I want to consider all that ice and water in the extreme north and south, around the poles.
If you’ve been paying attention, you might remember news of huge chunks of Antarctic ice breaking away. I’m talking chunks bigger than some states. Antarctica is receiving warmer weather than it’s seen in millennia, or maybe even millions of years. Some coasts that certain types of penguin have called ‘home’ for countless generations are becoming inhospitable for them. They already live at the bottom of the world, where are they supposed to go from there?
The Arctic Ocean is not doing any better. There is no land under all that ice at the north pole, just water. You might think, ‘That’s okay, because it takes a lot of energy to warm water up.’ Yes, it does. And yet, that water under that thick sheet of ice haswarmed up.*
If you look at a map or globe, you’ll see a bunch of islands above Canada. During Europe’s Age of Exploration, several well-provisioned ships made attempts to find a ‘Northwest Passage’ during the summers, trying to find a way to get around the Americas to do trade with the Orient. I don’t remember hearing of any of those excursions ever making it through, nor of any making it home again. At that time, I understand, whatever open channels of water that could be found among all those islands were unreliable and tended to close up and freeze a ship in place, even in summer. The last few years, so much of that ice has melted during the summer, that some cruise lines have offered cruises from one coast to the other, via the Canadian passage.
Something has happened to the Beaufort Gyre. That is a 60-mile-diameter pool of cold freshwater and sea ice located north of Alaska. It used to spin clockwise for 5-7 years, then slow down and start spinning in the opposite direction. This change in direction was caused by periodic cyclones that moved from the Northern Atlantic Ocean into the Arctic Ocean. But the North Atlantic has been warming up even faster than other parts of the world, and has failed to get the Beaufort Gyre to change direction in a dozen years or more.
So it’s just been sitting there, spinning and getting larger. And although it contains ‘cold’ water, that’s a matter of relativity. This spinning water contains twice as much heat now as it did 30 years ago. But it’s not sitting on top, like you’d think it would. It extends so deep, it is creeping under the Arctic ice sheet, which I understand can be a mile or more thick. Once it starts melting that ice sheet from below, well, how long before that ice sheet starts to break apart into gigantic icebergs, like the Antarctic ice has already started doing?
And what happens when all that ice breaks up and melts? Right, it raises sea level, which we discussed last time.
I had never heard of the Beaufort Gyre until a couple days ago, but I’m not done with it. From what I’ve been reading, whether it continues its current spin or starts going the other way, somebody’s in for a nasty time. Maybe it will come up next time.
