Australia warmer than we imagine; Monash professor

Professor Neville Nicholls.

Former prime minister’s business advisor Maurice Newman fired another attack at the Australian Bureau of Meteorology on Monday, arguing in The Australian that the weather bureau needs to be investigated for fiddling with the climate data that show Australia is getting warmer.

Technically known as “homogenisation”, the practice of removing biases from historical climate data has been well defended. In fact, you can do it yourself.

In his latest salvo, Newman claims that estimates of surface temperature trends by weather bureaus “diverge increasingly with satellite and radiosonde datasets”, and thus call into question the “integrity” of the surface data and the processing of those data.
