Iron Lady saw the dangers

THE FORMER BRITISH PRIME MINISTER, WITH A BACKGROUND D IN CHEMISTRY,CHEMISTRY UNDERSTOOD THE SCIENCE OF CLIMATE CHANGE AND TRIED TO WARN THE WORLD OF THE PERIL AHEAD IF NOTHING WAS DONE TO ADDRESS IT.

Decades before Greta Thunberg skipped school, and 16 years before Al Gore turned a slide show into an Academy-award-winning movie, the conservative leader of a small European nation took to the stage at a UN climate conference in Geneva and warned that climate change would prove to be the world’s “greatest test”.

The year was 1990. The leader’s name? Margaret Thatcher.

The Iron Lady is not exactly remembered as a prototypical environmental crusader, but with her training in chemistry she understood the science of climate change and, with her sharp political brain, she foresaw what it meant.

“No one should underestimate the imagination that will be required, nor the scientific effort, nor the unprecedented co-operation we shall have to show. We shall need statesmanship of a rare order,” she said.

Within a month, and for unrelated reasons, Thatcher lost power, taken down by her own party. But her message of concern has been echoed by smart leaders, and those who aspire to be – of all political persuasions – ever since.

The same year as Thatcher spoke, the International Panel on Climate Change released its first assessment report, showing global temperatures had definitely risen on preindustrial levels. We know what ensued: more reports, furious debate, endless conferences, agreements, protocols, targets, timetables, trade-offs, and way too many column inches.

But not nearly enough.

The IPCC’S most recent report, in August, revealed the myriad ways in which the climate has already changed, and warned of the irreversible damage to come if we do not act. Climate crises such as the millennium drought, the Black Summer bushfires and the bleaching of the Great Barrier Reef have made the issue pertinent, and indeed palpable, to the overwhelming majority of the Australian public. Here is what has already happened to our planet, and the scale of the problem we face.
