I looked up what you meant by FUD, and I'm guessing it's Fear, Uncertainty, and Doubt. I'll gladly accept that I'm questioning Uncertainty, but Fear and Doubt I leave to the media.
I would note that I asked the parent poster of this thread what he knew about this topic as he has apparently looked at the plant data and associated uncertainties as well as the ice-core samples; and I asked if an error analysis has been done on the ice samples, and how rigorous it would be. You jumped in with comments about helium balloons and 'fucking deniers.'
Of course I'll respect the effort to acquire the data, and I'll give it the appropriate scrutiny as suggested by the scientific method. I work in metal oxides also, and corrosion reactions to turn metal plus oxygen (oxygen being much larger than metals) into dirt are on the orders of years, not hundreds of thousands of years. So while some of your points about temperature and structure may (or may not) have merit, they are not proven and I asked someone who may know. What you're regarding as FUD, I'm regarding as business as usual.
