And it's the only one of those four actions that immediately addresses the methane and nitrous oxide, which are two of the most powerful greenhouse gases. Methane is 86 times as powerful as carbon and nitrous oxide is 310 times as powerful, which is to say, if you imagine the greenhouse gas effect like a blanketaround the Earth that's holding heat against the Earth, methane is a blanket that's 86 times as thick as carbon,
So make you guys hungry. Methane . Looks like Mars has even more methane than we ever thought, right?
You say, why, methane ? Methane now come mostly from livestock.The use of livestock for meat production has become now the second major factor of greenhouse gas effect.
What are your thoughts about that sort of nightmare Scenario That's an interesting question. Methane is molecule by molecule a much more effective greenhouse gas than carbon dioxide, but there's a lot less of it in the atmosphere.But its lifetime in the atmospheres a lot less than CO2.
So as the tundra begins to thaw, there is methane locked up in it and it's released through the atmosphere, and that is a positive feedback on the system. Methane is going up percentagewise almost as fast carbon dioxide, but quantitatively, so far, it's not the magnitude of the problem of carbon.
you get that measurement of the wobbling star, and you pair it with the light curve, the light curve is giving you the estimated Methane also does not really want to hang around in the atmosphere, especially when there's oxygen around.
There's lakes on Titan. Methane lakes, right? S. PETE WORDEN: Methane or ethane, depending on your preference.I think Pete was telling me about basically the concept of water ice being so hard, so frozen, that it
So the thing that makes it even more similar than Earth than anything else is the fact that, we have what we call a methane cycle, exactly like hydrological cycle I was talking about earlier on.So what you have is that you have bodies of methane , lakes and seas.
sufficiently impressed by all of this that they changed their whole plans for a, for a mission in 2016, 2018. And it's gonna be going to Mars to basically, to search for methane . Just a little view here of what it's like in -- this is a place called Paranal in northern Chile. This is the place where it never rains and so obviously there areno clouds. And this is where all the big mirrors are now being built, utterly spectacular, utterly dry. They have an eight meter telescope but, which is the largest that there is now.
non-conventional sources of fossil fuel such as tar Sands and natural naturally occurring bamans and oil shells or methane hydrates or indeed liquefied natural gas simply because the quantities are unknown and thecalculations would be far too complicated but but just looking at those three conventional sources coal
management all of that methane so i think people think of cattle they think of livestock sometimes when we hear methane or you you think of just something that isn't very pleasant landfills i guess aren't very pleasant but we don't usually relate it to foodso that's why i just wanted to throw those numbers out because i thought that they were really interesting so let me
spray salt water at the problem they some crackpots came up with the idea there was oh fissures shooting methane into the air that was creating the smog it wasn't man's you know machinery you know was nature playing alittle joke on us it didn't want us to populate Southern California
So play this -- take this technology and play it forward with much greater capability. methane on Earth. And we also know that there's biological ways to create methane . So the big question now is, is it possible
I mean it currently isn't, isn't it? Now methane is actually worse for the environment in terms of its global warming potential than carbon dioxide is.
And that's what makes the moon interesting and alien at the same time, because there's nothing really about this that is familiar to us. Liquid methane happens at minus 150 degrees centigrade. So it's an environment that we don't really understand.
So I just want to zip through a few more photos because they're just wonderful. reduces methane production through the growing cycle of rice.
with methane the roof collapsed the drilling rig fell in and
But methane and water vapor don't stick around in the atmosphere for long.
And that's used mostly to maintain emission besides deforestations and the other things. So methane is 20 times more active than CO2 for greenhouse gas effect. And that shows because of this extreme level of consumption, 120 kilos of meat in USA, 80 in Europe, only 3
So as the tundra begins to thaw, there is methane locked up in it and it's released through the atmosphere, and that is a positive feedback on the system. So methane is used a lot in fracking.
the methane levels just go crazy, and you get dissolved methane in this lake at 20 millimole, which is very, very unusual.
less methane emission so we should switch to kangaro meat instead of cattle
all methane bog methane is 21 22 times more potent than co2 is a greenhouse gas
So play this -- take this technology and play it forward with much greater capability. this methane is being created by biology on Mars?
or how fast methane breaks down in the atmosphere.
decays and produces methane , which is a powerful greenhouse gas.
They produce less methane .
It's methane . It's liquid methane .
There's methane , nitrous oxide, and carbon dioxide.
Chickens emit less methane on the whole.
A lot of methane contribution from them in terms of their digestion process.
If we have methane salts melting in the Arctic and possibly changing our atmosphere, I think having the ability to modify
So every methane is 21 times more powerful than CO2 at holding heat.
all this toxic methane started to escape the geologists thought the solution to the problem was gonna be to light this
So as the tundra begins to thaw, there is methane locked up in it and it's released through the atmosphere, and that is a positive feedback on the system. Industrial release methane . It's a very interesting-- So first of all, what is industrial release methane ?
you get that measurement of the wobbling star, and you pair it with the light curve, the light curve is giving you the estimated You can see methane .
you get that measurement of the wobbling star, and you pair it with the light curve, the light curve is giving you the estimated You put oxygen and methane into a sealed box at room temperature and pressure, it's going to turn into carbon dioxide and water vapor.
Maybe more methane . Methane , I was going to say.
But there's rain that appears. It's ethane or methane rain.
And then you will have evaporation, and you have condensation, and then methane precipitates. And you have methane rain on Titan. And so what happens then is that in the topography, and the topography close, then you will have accumulation of methane .
And so people wanted to understand how long those lakes were going to last, how they were going to be replenished. What is the methane cycle? And if you have somewhere a sink of methane , if there is really an ocean in the subsurface of Titan, then you
have a mechanism now to have this cycle that we are talking about. A question of methane or water? Well, it's an interesting question.
Smelly, because it's methane . And we know what methane can smell here, it's not pretty. And explosive. I don't know if it meant by that that you probably shouldn't be smoking.
Van Jones: That's methane , that's what it is.
And this is methane , this is not CO2. So you take one of the most potent greenhouse gases and you flare it.
ignoring all the unconventional sources even ignoring all the other greenhouse gases such as methane and and and and the the trace gases which um Can can be very powerful greenhouse warming agents uh we we end up with um only being able
atmosphere and that's even what i thought was interesting with that stat it's more than coal mining and it's more than manure management all of that methane so i think people think of cattle they think of livestock sometimes when we hear methane or you you think of just something that isn't very pleasant landfills i guess aren't very pleasant but we don't usually relate it to food
than normal all those methane bogs are melting and the methane is going to or
or more releases methane however in the only place where we have statistics is in the Gulf only about twenty percent of
So play this -- take this technology and play it forward with much greater capability. And there's methane lines in the near infrared. It's kind of tricky cause there's methane in the Earth's atmosphere. So again we make use of this Doppler shift.
