The rapid release of methane into the earth's atmosphere 635 million years ago caused rapid warming and mass extinction of species, disrupting the climate for more than 100,000 years.and may happen again in the near future, reported in Nature . (1)

The concern is that it could take a relative small rise in temperature to start unleashing the gas,which would then trigger an unstoppable warming cycle. (2)

The first evidence that millions of tons of methane 72 times more potent than carbon dioxide over 20 years(3)is being released into the atmosphere from beneath the Arctic seabed has been discovered by scientists(4) at Sep 2008 according to The Independent. (5)

The livestock industry is the number one producer of methane which is the most potent greenhouse gases. The UN reports that meat production emits 37 percent of the world's methane gas (6)


We have to save this planet, so that we’ll be able to stay, first. Because if the ice all melt, if all the poles all melt out, and then if the sea is warm, then the gas might be released from the ocean, and we might all be poisoned. It’s a lot of gas.

If you see the Singapore lecture, I already warned that we have to change the way we live, otherwise it’s too late. It was 10 or 15 years. Or before that, I always talk about how we deforest our planet, yah? Meat eating and all that contributes to a lot of damage to our Earth planet, you know.

Scientists say many things. They are listening now, but I just hope they do it fast. It just takes action. All the governments in the world really take it now seriously. It’s just I’m worried the action might be too slow, that’s all.

Because the ice reflecting the sun, you see, so send it back into the space, but the ice is melting
so fast now, that there’s not enough reflection and because the sea is already warm, it melts the ice. And because the ice melt, the sea warmer. You see what I mean, the cycle?

The way it is going, if they don’t fix it, 4 or 5 years time, finito. No more. It’s really that urgent.

Hallo, noble viewers, and welcome to Planet Earth: Our Loving Home. Today we’ll explore the phenomenon of mass extinction, by which large numbers of species cease to exist.

Scientists say that many such events have occurred over the course of Earth’s history, and with the acceleration of global warming they warn that our planet may be headed toward another one.

Today Dr. Peter Ward, a professor of Earth and Space Sciences at the University of Washington in Seattle, USA and an astrobiologist for the National Aeronautics and Space Administration (NASA) will share his knowledge.

Dr. Ward is an expert in the area of mass extinction and has written more than a dozen books, including the critically acclaimed “Under a Green Sky: Global Warming, the Mass Extinctions of the Past and What They Can Tell Us About Our Future.”

Prof. Ward: What has caused mass extinctions is still one of the really interesting and driving questions in geology and biology. If you would have asked me that question between 1980 and 1990, I would have told you that asteroid or comet impact on the planet would have been the major or perhaps the only cause
of past mass extinctions.

It really now looks like that was a unique event, and that the other 14 mass extinctions were caused by short-term climate change, in almost every case global warming.

HOST: According to Dr. Ward, changes to the composition of the ocean can initiate a mass extinction.

Prof. Ward: The ocean state that we have now is one where our oceans are mixed,and that means that the composition of water, the chemistry of sea water at the top is almost identical to that at the bottom.

And by chemistry I don’t just mean the atoms making up the water, I mean the entire body of water itself, which includes dissolved gasses. Now gas in this atmosphere, if we bring out a new vat of seawater that’s been out of gas, that gas sitting here will pull down molecules of oxygen, carbon dioxide, nitrogen and it will dissolve away; just like you put sugar to water and stir it, well, gas does the same thing.

The amount of oxygen at the surface of the ocean is almost identical to the amount at the deep bottom, that’s the current ocean state. But the second ocean state is there is oxygen at the top, but none on the bottom.
The third ocean state, there is not much oxygen anywhere, and hydrogen sulfide is present; three ocean states.

Prof. Ward(m): The mass extinctions happen when you move to either of the other ones.
