Methane burps disproved? Gassy emissions no longer in suspect dock for melting the last ice age.

It is usually released from swamps or through biomass burning.

I thought this was going to be an article about democrat senators. Misleading title there.

Oh thank God for the gassy emissions. My wife (and I) will be relieved on our way out of the movie theatres.

Volcanos Helped Slow Ocean Warming  

Debris form a volcanic eruption that occurred more than a century ago still lingers in the Earth’s upper atmosphere where it is helping to keep ocean temperatures cool and offset sea-level rising, a new study finds.

Spewed ashes and aerosols from the 1883 Krakatoa volcanic eruption in Indonesia are helping to block sunlight and reduce ocean temperature warming.

Good thing we have nature on our side.  ;-)

Global warming is caused by the sun, you idiots.

Kennedy? Can you make Methane from pure alcohol?

"In most cases, there is evidence that the methane values only began to rise several decades after the temperature started to climb."

Interesting indeed. This cooincides with data that shows CO2 increases that followed temperature spikes. If CO2 nd CH4 are "potent" "greenhoue gases", then the reverse would be true.

It appears that temperatre rises probably accelerated the state of decay for dead vegetation which then released CO2 and CH4 (the bulk of CH4 and CO2 does come from vegetation decay). Again, this points to something else causing the temperature spikes.

Gee, folks... ya think it might be the Sun and increases in the main "greenhouse gas", water vapor???

Maybe nature, but Nature Magazine isn't, IMHO. Thanks for the pic and the link.

One of the troubling results of Arctic warming is the melting of vast areas of permafrost in North America and Siberia. When frozen Co2 and other gases are sequestered. When it melts significant amounts of Co2, and presumably other gases are produced.

Another troubling result of Arctic warming is the melting in summer of the Arctic ice cap. It has been shown by recently released classified nuclear submarine data that around half the thickness of ice has melted in the past 30 years. Currently this ice reflects energy back from the earth. Once it is gone the ocean will absorb heat from the sun further accelarating the warming process.

How about Global Warming on Mars?

The warming was caused by these guys.

But it is also trapped in huge amounts in some ocean-floor sediments, where it lies buried in a strange kind of ice known as 'methane clathrate'

I am curious as to why the article did not mention that single greatest source of methane on the earth is termites...

Thanks for the ping.

Disproven. The MOST recent data shows that the submarine data were wrong, and that the difference is due to normal migration of the ice masses. There's an article posted here in the last few days about it.

I thought I read that this was not a valid story and that the submarine data not correct?

I know a man who wrote a fiction novel about a massive methane hydrate release. In the book, it brought about masive destruction. It made for a good read, but I don't believe in man-made global warming. I'm old school, I still believe God is in control. Silly me!

This story needs a thread of it's own:

Volcanic eruption cut warming in 20th century

The 1883 eruption of Krakatoa—a volcano near the Indonesian island of Rakata—ejected more than six cubic miles (25 cubic kilometers) of rock, ash, and pumice and generated the loudest sound ever recorded by human beings. The tsunami that followed the eruption killed 36,417 people according to official records. The eruption destroyed two-thirds of the pre-existing island of Krakatoa and subsequent eruptions at the volcano since 1927 have built a new island, called Anak Krakatau. Anak Krakatau has since erupted on several occasions including the pictures eruption in 1992.

Eruptions regulate sea temperatures

The colossal eruption of Indonesia's Krakatau volcano in 1883 may have helped offset the effects of human-induced ocean warming, according to Lawrence Livermore Lab scientists.

Krakatoa's chilling effect

So what about volcanoes? Yes, they do release CO2 into the atmosphere, but they do more than that. When you take several million tons of rock and blow it into tiny little pieces, you end up with ash, and lots of it. So much, in fact, that along with breathtaking sunsets come severely affected climates. Following the huge eruption of Krakatoa in 1883, enough reflective volcanic aerosols were ejected into the atmosphere that the following year was known as the year without a summer.

Krakatoa helps to keep Earth cool

The explosion generated the loudest sound in human history, and was heard from more than 2,500 miles away.

According to a study published today in the journal Nature, the sulphate aerosols and a worldwide volcanic dust veil acted as a solar radiation filter, reducing the amount of sunlight reaching the surface of the earth.
