I am no photo artist, and my best camera is, well, my phone. That’s it.

Even so, a few minutes ago I felt compelled to take a couple of photographs. We are a few minutes away from sunset and a big storm just began. Then I looked out my window and I found the building across the street brighter than the sky above.

The light came from the other side of the sky. The Sun was not visible but the sky in that direction was bright enough to light things up.

Photographs (especially, photographs taken with a phone) really don’t do these sights justice. The contrasts were amazing.

Some people call squirrels furry rats. Yet they are cute.

Cute enough, it seems, for people to feed them donuts. Or was this donut stolen?

A moment in a squirrel’s life, caught by my wife earlier today with her cell phone camera.

Not sure how I landed on this page (maybe I was reading too many gloomy assessments of the post-Brexit world?) but here it is anyway: An incredible collection of dioramas by artist Lori Nix, titled The City, depicting a post-apocalyptic world:

A world without humans. Scary visions. Real life examples exist, of course, in places like abandoned sections of Detroit or the Zone around Chernobyl, to name just a couple of prominent ones.

Recently, someone on Quora asked where one would place a time capsule to survive a trillion years. Yes, a trillion. Ambitious, isn’t it? Meanwhile, we have yet to learn how to build things that survive a mere thousand years or less. There is nothing, absolutely nothing that humans constructed, or can construct, that will survive in any recognizable form for a trillion years, be it on the Earth, in space, or on another planet.

In the fourth volume of the Hitchhiker’s Guide to the Galaxy “trilogy”, we learn that just before the Earth was about to be destroyed by the Vogons to make way for a new interstellar bypass, the whales left. They left behind a simple parting message: “So long and thanks for all the fish.”

Which makes me feel rather alarmed now that I am learning that hundreds of North Atlantic right whales went missing. I hope it’s not a bad sign.

Eons ago, back when dinosaurs still roamed the Earth, George W. Bush was still a first-term president, there were only five Star Wars films and Java applets were still cool, I created an applet that showed what Mars would look like if its surface was covered by oceans.

I liked what I did so I added the capability to use other data sets, including data sets for the Earth.

The applet is worthless now, or almost so. Java applets are no longer supported in Google’s Chrome browser. They were never really supported on mobile platforms. Even in browsers that do still support Java, the user has to go through hoops and add my domain as a security exception (not recommended) to allow my unsigned applet to run; all this a result of vain attempts to address the security risks inherent in Java and its implementations.

Anyhow, the applet still works if you can run it. And this is what the Earth looks like today:

Someone recently asked what our planet would look like if it was devoid of oceans. If sea levels were 5000 meters below the present value, the planet would still have a shallow ocean in place of the Pacific. Otherwise, though, it would be mostly dry land with only some inland seas where the Atlantic and the Indian oceans used to be.  It would be possible to walk from pole to pole without wetting your feet; however, you might get a tad thirsty along the way, and there’d not be much rain either.

Decrease ocean levels by another 1000 meters to 6000 below present sea levels, and the last remaining ocean is gone:

Finally, at 7000 meters, the only open water that remains would be in places of the deepest ocean trenches. (Mind you, even then, some of these seas would still be up to four kilometers deep.)

I was also asked what things would look like if the seas rose. There is a surprising amount of change to coast lines by an increase of a mere 50 meters:

Florida is gone; Western Europe looks noticeably different. Increase the sea level rise to 200 meters, and now the change is rather more dramatic:

earth+0200

India is now an island or almost so (there may be some land bridges connecting it to the Asian continent that are too narrow to be visible at this map’s resolution). Much of Europe, Russia, Australia, South America, and the eastern parts of North America, gone.

Finally, at 1000 meters, only mountain ranges remain:

With this little dry land left, there is not much in the way of storms; like Jupiter with its Great Red Spot, the Earth might also develop long-lived storms that circumnavigate the planet many times before dissipating.

It has been in the news recently that the baboon exhibit at the Toronto Zoo had to close temporarily. The reason: Following the death of the matriarch, there was a power struggle.

The reason why I find this fascinating is that these baboons weren’t fighting for food. They were not fighting for sex. They were not fighting for a more cozy sleeping place or anything else tangible.

No… they were fighting for power.

That such an abstract concept not only exists in the animal world but may even prompt a vicious fight might upset those who maintain illusions about the noble animal world. But then, perhaps the animal world is not that different from the world of humans.

We all came from the same place, after all.

The next time a bellicose politician, ruler or warlord makes a threat, brandishing fancy weapons of war, in some vainglorious quest for power, just think of one word: baboon.
