once more ... the Romans did it already 2000 years ago! this time: burning so much wood that they increased the methane level in a way we can still measure it in ice cores ...
nice story from Andrés:
my only concern:
"At Gran Sasso, the ingots will be melted into a 3-centimetre-thick lead lining that will surround the cubic CUORE detector. Before the ingots are melted down, the inscriptions on each one will be removed and sent back to Cagliari for preservation. "They are trademarks, bearing the names of various firms that extracted and traded lead," explains Donatella Salvi, an archaeologist at the Cagliari museum.
