Also known as relief typographic printing, letterpress printing employs the use of type or designs cast or engraved in relief (raised) on a variety of surfaces which can include metal, rubber, and wood. Opposite of intaglio printing, in letterpress printing the ink is applied to the raised printing surface. Non-printing areas or spaces are recessed. Impressions are made in various ways. On a platen press the impressions are made by pressure against a flat area of type or plate. Flat-bed cylinder press printing uses the pressure of a cylinder rolling across a flat area of type or plate to create the impression. A rotary web press uses a plate that has been stereotyped (molded into a curved form) which presses against another cylinder carrying the paper.
Paper you may have, but couldn't find on "The phase relation between atmospheric carbon dioxide and global temperature"
CO2 lagging temp change, which really turns the entire AGW argument on its head:
► Changes in global atmospheric CO2 are lagging 11–12 months behind changes in global sea surface temperature ► Changes in atmospheric CO2 are not tracking changes in human emissions.
