Climate scientists first laughed at a ‘bizarre’ campaign against the BoM – then came the harassment

(The Guardian, 6 May 2023) Former Bureau of Meteorology staff say claims they deliberately manipulated data to make warming seem worse are being fed by a ‘fever swamp’ of climate denial.

For more than a decade, climate science deniers, rightwing politicians and sections of the Murdoch media have waged a campaign to undermine the legitimacy of the Bureau of Meteorology’s temperature records.

Those records say Australia has warmed by 1.4C since 1910, the year when the bureau’s main quality-controlled climate dataset starts.

Extremely hot days come along more often than they used to, and the warming trends are happening everywhere, at all times of the year.

As a target for those with an often visceral distrust of the established science of human-caused global heating, the bureau’s temperature record might be seen as ground zero.

“This has frankly been a concerted campaign,” says climate scientist Dr Ailie Gallant, of Monash University. “But this is not about genuine scepticism. It is harassment and blatant misinformation that has been perpetuated.”
