Revisited: Weight of the world – the climate scientists who saw the crisis coming

Science Weekly revisits episode one of this 2023 mini-series from
Full Story. Pioneering Australian scientists Graeme Pearman, Lesley
Hughes and Ove Hoegh-Guldberg saw the climate crisis coming.
Pearman predicted the increase of carbon dioxide levels, Hughes
foresaw the alarming number of species extinctions and
Hoegh-Guldberg forecast the mass coral bleaching events we’re
seeing today. All three went on to become some of the country’s
most respected experts in their fields, travelling the globe,
briefing leaders, and assuming the world would take action having
heard their alarming findings. In part one of this three-part
series, these climate change scientists reveal the moment they
realised the planet was heading for certain catastrophe. What did
they do when they found out? How did they think the world would
respond? And how do they feel today, looking back on that moment of
cognisance?. Help support our independent journalism at
