A view of another dwarf planet: Ceres

I guess I should know this, but there’s a dwarf planet between Mars and Jupiter called Ceres. Apparently, it’s been known about since the early 19th century. And NASA put together some images of it from a recent mission:

So how big is this thing? Here’s an image of various objects in the asteroid belt:

Using the moon as a reference point, Ceres would be the object numbered 1 on the far left. So that’s small and that means it isn’t a planet. It’s a dwarf planet. Like Pluto, which, I was surprised to learn not too long ago, is also smaller than the moon.

So Ceres is about as wide as Texas.

Dealing with climate change isn’t about saving the Earth

The line on climate change is that we have to address it in order to save the Earth. That’s not the best argument.

The Earth is going to be around for a couple of billion more years. And there will be life on Earth for a good chunk of that time. But that doesn’t mean humans are going to be around that long.

Ask the dinosaurs. The asteroid that hit the planet 65 million years ago (no, creationists, the Earth is not 10,000 years old) threw material in the air that led to rapid, extreme prehistoric climate change. Dinosaurs disappeared and mammals evolved and took over.

Now the mammals are creating their own, extended climate change. Since we’re going to keep it up, because the danger still doesn’t seem to register with people, it will be interesting to see what life form takes over after we’ve killed ourselves.

So climate change isn’t about saving the Earth. It’s about saving humanity. And humanity sure acts like it doesn’t want to be saved.
