since all worldwide levels rose simultaneously throughout the same year, it is now believed this may be part of a natural cycle in mother nature
It’s an election year, all that gas from the Obama World Tour no doubt.
Bump....
Great informative post, straight and to the point. I never heard of any of this before.
Ya think?
And Ozone holes, and DDT, and nuclear winter, and bird flu....
Ping, FYI.
Good try, but it doesn’t pass the ‘smell test’.
Methane levels have been much, much higher, > 250 years ago, but still is only .0000034% of the atmospeheric volume.
Methane comes from many chemical reactions - not all of them organic. “growing rice” is insignificant.
Please go back and do a little more research, and don’t be sucked in by carefully crafted “plausibility”
As someone else noted, this doesn't contradict GW theory; the lack of methane increase over the past decade was the real mystery. So now it has started going up again. So there's two questions: why did methane growth in the atmosphere stop, and why did it start going up again?
(My theory: Chipotle. Have you seen how many people go to Chipotle for lunch???!!! There were 14 Chipotles in 1998 and nearly 800 now. That's a gastro-intestinally disturbing trend.)
AGW is a huge political hoax, perpetrated by algore. The science does not support it.
I don't want to get into it. I'm not even posting the most recent study results regarding Antarctica. Someone else can. But I will say one thing, clearly: it is not a "political hoax". It is indeed a scientific issue. The image below illustrates why. Investigating how the changing concentrations of CO2, CH4 and other radiation-absorbing gases in the atmosphere will affect the climate of the Earth is properly the province of science. The factors which affect Earth's climate are changing, and the Earth's climate is changing, and science needs to determine what is affecting what and by how much.
There are indeed political and societal implications. But it's not a political hoax. 'Nuff said.

That graph looks scary, till you realize it only covers a range of 100 parts per million.
MIT welcome to the party. Too bad it took you so long to figure it out.
LOL - Mona Loa - the 9th largest natural CO2 vent on the planet...
Great science there buckwheat...
Good news. Now I can pass my righteous wind again.
And now ~80 ppm higher than anything nature achieved over the past 650,000 years. That's why science is examining the issue.
Where do you get this crap? Back of a Koolaid packet?
It's spelled "Mauna", Lisa, and if you think scientists don't know how to detect volcanic gas emissions when doing their atmospheric sampling, think again:
Mauna Loa Volcanic Emissions 1958-Present
"At night a temperature inversion forms near the ground, trapping volcanic emissions coming from Mauna Loa summit fumaroles in a layer tens of meters thick. Down slope winds sometimes transport these emissions to the observatory, where they are detected as a "noisy" increase above smooth baseline levels for some gases. A volcanic component can be estimated by taking the difference in concentration between periods when the plume is present and periods immediately before and after that exhibit baseline conditions. The most significant volcanic gas is CO2, which has been monitored since 1958 through three eruption cycles. Volcanic CO2 is greatest shortly after an eruption and then decreases exponentially over the subsequent years. Right after the 1984 eruption, Mauna Loa emitted as much CO2 as an American city of 40,000 people. By 2005, these emissions had fallen by a factor of about 100. This suggests that a reservoir deep beneath the summit is recharged with fresh, CO2 rich magma during and immediately following an eruption which is then quiescently outgassed at an inverse-exponential rate. There were substantial emissions of SO2 and aerosols following the 1975 eruption and much lower levels were seen after the 1984 eruption. By 2000, SO2 and aerosol emissions from Mauna Loa had fallen below detection limits. The CO2 and SO2 data is examined weekly for any significant events which may signal renewed activity in the volcano. The long-term records are updated yearly."
And is this CO2 curve located near any volcanic vents?
