From the study report:
 
More study
 
Prinn has said, "The next step will be to study [these changes] using a very high-resolution atmospheric circulation model and additional measurements from other networks. The key thing is to better determine the relative roles of increased methane emission versus [an increase] in the rate of removal. Apparently we have a mix of the two, but we want to know how much of each [is responsible for the overall increase]."
 
The primary concern now is that 2007 is long over. While the collected data from that time period reflects a simultaneous world-wide increase in emissions, observing atmospheric trends now is like observing the healthy horse running through the paddock a year after it overcame some mystery illness. Where does one even begin? And how relevant are any of the data findings at this late date? Looking back over 2007 data as it was captured may prove as ineffective if the data does not support the high resolution details such a study requires.

 
All that says is that we still know nothing about the root causes of the warming we have observed.
 
Which we already knew. Which other people have already said before.

This was in response to those that still believe there is a consensus. If you find the MIT study boring so be it. It is still a part of the puzzle and further evidence that we know very little about Climate Change. For sure not enough to shut down life as we know it and try to go back to 1990.

Yawn? Come on Larsb, why would you attempt to belittle and yawn at a scientific study from MIT? Where is that open and well read mind of yours?

I think disappearing ice in the artic is indisputable as well. However, while the Ross Ice sheet in the Antartic may also be shrinking, the total amount of ice in Antartica is increasing. Antartic ice contains over 90% of the world's fresh water.

OK, I am not disputing your claim that Antarctic ice contains over 90% of the world's fresh water, but...where in the heck did all that ice come from during the ice age when glaciers covered so much of the globe?

Wasn't YAWNing the MIT study.
 
I was YAWNing Gary's posting something that declared something we already knew......that we don't know what's causing the warming.......
 
Duh.
 
YAWN.........

If you already knew about the methane distribution, why didn't you let MIT know? That would have saved them a lot of time and money. We are here to determine if the automobile is the cause of GW/CC. That was just one more bit of evidence to the contrary. I do not remember you or anyone else posting that information before. If any evidence that does not confirm your belief in man made GW bores you, maybe you should join Al Gore's team. There is always room for one more zealot that will blindly follow his THEORIES.

Methane as a GHG is not new news. This is nothing "contrary" to man-made GHG. We have always known that Methane was a GHG.
 
And the CONCLUSION is what I was yawning, not the data or the method.
 
"One thing does seem very clear, however; science is only beginning to get a handle on the big picture of global warming. "

That's the big DUH.

I think larsb wants us back to 1790. Anyone up for a little plague?

Glaciers come from snowfall. Summer and winter temperatures are insufficient to allow for snow melt and so build up year after year. In time the weight of the snow on the snow beneath it turns to ice from the pressure. The continually building pressure and gravity cause the ice to "flow." Antarctic ice is miles thick at this point.
