"There is some CO2-water vapor feedback. But it's not operating on a global scale. The modellers cannot accurately separate water vapour from the effects of clouds and rainfall."

Contemporary poetry ... tries to transform the sign back into meaning: its ideal, ultimately, would be to reach not the meaning of words, but the meaning of things themselves. This is why it clouds the language, increases as much as it can the abstractness of the concept and the arbitrariness of the sign and stretches to the limit the link between signifier and signified.
