The Australian Climate Council wrote a report explaining how the gutting of climate science at the main Australian research institute, CSIRO, will harm climate science in Australia: Flying Blind: Navigating Climate Change Without CSIRO. The Australian climate research program is the most important one in the Southern Hemisphere and seriously hurts humanities understanding of the climatic changes there, which are anyway already understudied because most research happens in the global north.
The report also shows that these planned cuts to CSIRO’s climate science division would breach Australia’s commitments under the Paris agreement.
While destroying research can be done quickly with such a decision, building up a research program takes decades. A next Australian government will not be able to get to the same level again by renewing funding. That will take a long, long time.
It is very ironic that this decision comes from a right wing government that does everything to increase the use of coal and thus make climate change worse. It comes from a group that often advocates an adaption-only strategy to climate change. If you want to adapt, you need to know what climatic changes you need to adapt to. For that you need to know what will happen at a local scale, often with respect to changes in extreme weather, often what will happen with precipitation and storms. It is cleat that climate change is real, that the global mean temperature will keep on increasing if humanity refuses to act, but all those "details" we need to adapt are far from clear. Australians needed that information, farmers, engineers, companies, governors and majors, will find that CSIRO will not be able to answer their telephone calls.
