Shell's 1991 warning: climate changing ‘at faster rate than at any time since end of ice age’

Critics say public information film shows Shell 'understood the threat was dire, potentially existential for civilisation, more than a quarter of a century ago'

" 'Shell knew': oil giant's 1991 film warned of climate change danger

Climate change "at a rate faster than at any time since the end of the ice age - change too fast perhaps for life to adapt, without severe dislocation". That was the startling warning issued by the oil giant Shell more than a quarter of a century ago.

The company's farsighted 1991 film, titled Climate of Concern, set out with crystal clarity how the world was warming and that serious consequences could well result.
