How to pronounce “albedo” in English

And over time, you're determining the change in the reflected light.The albedo changes over time.You can start to get a sense of what the spin rate is.

good. We, all you have to do, it doesn't matter where it is cause when you take a molecule of CO2 out of the air and the planet, it doesn't matter where you take it out; it's not likethe albedo of the ocean by dumping Special K breakfast cereal into the Arctic Sea. Another who thought that putting, setting off, shooting a nuclear weapon at the moon to cause moon

One of the most important ones is called the ice albedo feedback.So the albedo is the amount of heat energy that is incident on the Earth from the Sun, which gets reflected back into the atmosphere.Typically, white surfaces like snow and ice, they reflect more heat energy.

can say that it's negative because it's pretty dark.So we have an albedo effect factor of 0.15.But if we include clouds, is double of it.

Now, about one third of that bounces straight off into space because of white clouds and because ice.Because of the albedo, it reflects it.You all know that because, hopefully, Google sent you all skiing to bond and to actually make you feel better about yourselves,

You all have to wear sunglasses because of the reflection of the sunlight off the eyes.So the albedo of the Earth means lots of sunlight is reflected.Now, the interesting thing is a little bit is absorbed by the atmosphere.

Francisco that uses computer simulation and modeling to design thermodynamically sustainablelandscapes with low albedo surfaces and storm water retention, and that we calculate could save the city some billions of dollars in energy and environmental costs.But that's not what you came here this morning to hear about. So let me get on to the actual topic of my talk and I'll tell you a little bit at first about how I'm structuring the

There are a number of different feedback loops that feed into the temperature of our planet.One of the most important ones is called the ice albedo feedback.So the albedo is the amount of heat energy that is incident on the Earth from the Sun, which gets reflected back into the atmosphere.

I had to slip that in in case you forgot I was Catholic.I make it hot like a planet with low albedo, like me rocking a trench coat on a beach instead of a Speedo.

But it's not the only step.So now I'm going to talk about albedo.But first, I'm going to diverge and talk about Jayne.

that was the step that I just showed you.And we can back out what the actual albedo, or inherent brightness, of the surface was.So what we would do is we would take images that look like this, on the left, which is an actual scene, and you

And you can go back and use that to follow up with spectrometers and other kinds of data.So that's the kind of work we do with albedo and the moon.So now I'm going to jump to Mars.

good. We, all you have to do, it doesn't matter where it is cause when you take a molecule of CO2 out of the air and the planet, it doesn't matter where you take it out; it's not likepeople right now, and it's this albedo management stuff that is the real dangerous and interesting part of this. But I think that, when I was researching this, there's many--this idea

But we don't. Or we assume, for now, we don't.Well, the brightness will depend upon the overall reflectivity or albedo of the face.Is it white or black or gray or other color?

So we absorb more of the heat energy into the Earth, which then increases the temperature.It melts more of the snow and ice, and that reduces the albedo further.We absorb more heat energy.

to us, because there are the potential for these nonlinear phenomena, these feedback loops, to kick in and to take things somewhat out of our control.Again with climate change, it's interesting that the temperature through this ice albedo feedback loop doesn't always have to go up.So there's a hypothesis called the snowball Earth hypothesis that suggests that tens of thousands of years ago, the whole Earth was just a giant ball of snow and ice,

industry, as I said before.The amount of energy that the Earth can reflect from the sun, we call it albedo, the albedo effect.So the higher is the number in the bottom right, the better for us because the temperature will be lower.

You can see there the Rosette, the instrument I told you.Any chances it can offset the major negative feedback loops, like albedo loss from ice melting, decreasing, CO2 storage, permafrost melting releases,

In that process, did you come out with a favorite?but I learned from your book that DAN, the Dynamic Albedo of Neutrons experiment, has an ion cannon.

So the higher is the number in the bottom right, the better for us because the temperature will be lower.This is a picture if we take out all the clouds-- if we take them out all of them-- so we will have the albedo from the desert, whichare quite bright too, from the polar regions, the ocean-- and the albedo from the ocean, we

This is a picture if we take out all the clouds-- if we take them out all of them-- so we will have the albedo from the desert, whichare quite bright too, from the polar regions, the ocean-- and the albedo from the ocean, wecan say that it's negative because it's pretty dark.

So we did not know the shape of the comet before we arrived.All that we had was very, very grainy photogrammetry, which is basically albedo information, when you see these repeated lightenings and darkenings.You can infer something about the shape.

But first, I'm going to diverge and talk about Jayne.So one of the things that I wanted to ask you is, in my attempt to talk about albedo, is what color is Jayne's shirt?Is it black? Is it purple?
