CSIRO’s 7 global mega trends probably won’t surprise, digital and data, health etc, but the first among them is ‘Adapting to a changing climate’. If we don’t work that one out, the other 6 are barely relevant. Faffing around with 26-28% or 43% is just that, faffing, when the science tells us that even a 75% reduction in emissions will not be enough. Over to you politicians, scientists are doing what they must do.
