It is ''pretty bloody hot'' on Harry and Nicola Bussell's property - 50.8 degrees, in fact. It is a new high for the stunning sheep farm nestled at the foot of the Victorian alps in Carboor.

Despite the record - and Victoria's second significant heatwave in five years - the Bussells are sceptical humans are changing the temperature or climate.

''I am definitely not convinced,'' Mr Bussell said this week. ''The climate is changing all the time. It's been changing for millions of years.''

Ms Bussell said for her debate over whether the planet is warming was not helpful. She said qualified people sat on both sides, and it was arguable Australia could do anything about it at any rate. She said helping farmers manage the variable climate they have always faced would be more useful.
