Yes. Paul Ehrlich (Stanford biologist) — Repeated 1960s–1970s predictions of massive famines and hundreds of millions starving in the 1970s–1980s due to population and environmental limits. Food production rose instead (Green Revolution). Kenneth Watt (ecologist) — 1970 Earth Day claim that the world would be about 4°C colder by 1990 and 11°C colder by 2000 if trends continued. Various 1970s scientists — Multiple researchers and media reports around 1970 predicted a coming ice age or significant cooling by 2000. Warming occurred. James Hansen (NASA) — 1988 congressional testimony scenarios; the high-emission pathway overpredicted subsequent warming. Later specific comments on rapid Greenland melt and sea-level implications have not matched the timelines suggested. Wieslaw Maslowski (U.S. Navy researcher) and related extrapolations — Early 2000s claims (widely amplified) of possible ice-free Arctic summers within a decade or by ~2013–2016. September Arctic sea ice has declined but has not disappeared. Individual researchers / media-amplified claims — Multiple statements around 2007–2009 projecting ice-free Arctic summers by 2013–2018 (e.g., some linear extrapolations of volume loss). Still not occurred. Mostafa Tolba (UN Environment Programme executive director, scientific background) — 1982 warning of environmental catastrophe “as complete, as irreversible as any nuclear holocaust” by 2000. 1989 UN environment official — Prediction that entire nations could be wiped off the Earth by rising seas if extreme action was not taken by 2000. Early high-end sea-level or ice-sheet collapse statements — Some individual scientists in the 2000s suggested rapid multi-meter rises or irreversible West Antarctic collapse on short timelines that have not materialized at the rates claimed. Extreme scenario reliance — Heavy use of RCP8.5 / SSP5-8.5 (“business as usual”) pathways in research and communication for years; these required implausibly high coal use and emissions trajectories that are now widely regarded as unrealistic. I left celebrities and other crap ( Al Gore, Prince Charles, John Kerry, Greta Thunberg, Leonardo DiCaprio, UK Prime Minister Gordon Brown etc.) out for now...
