Timescape (1980)

Scientists facing environmental collapse try to send a warning backwards, while researchers in the earlier period struggle to recognise what their experimental interference might mean. Benford makes professional rivalry, domestic strain and the difficulty of being believed part of the scientific process. Moderate to high technical density, especially around the fictional tachyon mechanism. Its imagined 1998 belongs to a novel published in 1980, not to a contemporary account of environmental history.
