A BAD ski season three years ago - right after a great one - had The Age and other alarmists blaming global warming. The CSIRO, once our top science body, fanned the fear by claiming resorts such as Mt Hotham and Mt Buller could lose a quarter of their snow by 2020.

In fact,*this year was another boom one for skiing, with Mt Hotham and Mt Buller covered in snow five weeks before the season started.

What’s more, a study this year in the Hydrological Sciences Journal checked six climate models, including one used by the CSIRO.

It found they couldn’t even predict the regional climate we’d had already: “Local model projections cannot be credible . . .”

It also confirmed the finding of a study last year in the International Journal of Climatology that the 22 most cited global warming models could not “accurately explain the (global) climate from the recent past”.

As for predicting the future. . .

Lesson:*The CSIRO’s scary predictions are near worthless.*
