A Trump presidency in the US could have serious impacts on Australia's climate science and other research, with fears the cuts could be "CSIRO times 50".
Donald Trump's pledge to end US participation in the Paris climate agreement and expectations he will appoint climate change denier Myron Ebell to a key environment role has scientists bracing for fallout.
The state of our climate in 2016
Australia is already experiencing an increase in extreme conditions from climate change - and it's projected to get worse.
Australia's climate research relies on many US programs, some of which have been targeted by the Republican-controlled Congress. President Barack Obama resisted cuts to agencies such as NASA and the National Oceanic and Atmospheric Administration but he will leave office on January 20.
At the extreme end, a Trump administration could jeopardise global climate efforts by withholding access to data that underpins climate models used by the Intergovernmental Panel on Climate Change, said David Karoly, an atmospheric scientist at Melbourne University.
"All the [Coupled Model Intercomparison Project] data is stored on US data servers," Professor Karoly said, adding the US is the only place storing all that information.
Any interruption could mean the next IPCC assessment potentially doesn't proceed, which "would be an enormous setback for climate science", he said.
Others, though, noted that while earlier model data were housed on servers belonging to the US Department of Energy's Lawrence Livermore National Lab, an international Earth System Grid Federation now shares the load. The network is led by the US but has nodes elsewhere, including in Australia.
Christian Jakob, a Monash University professor who attended a recent CMIP gathering in the US, is less pessimistic about an interruption to data access. Still, future phases of the modellin could be affected if other nations didn't step up to fill any US void.

Australia's Bureau of Meteorology, CSIRO and universities rely on NOAA to supply their key ocean model. Cuts "would have implications for us very directly", Professor Jakob said. "Everyone is vulnerable."

"Everything's connected - if you remove a piece in one corner, you'd better do a careful analysis of what the consequences are," Professor Jakob said, adding the CSIRO cuts were "an actual intent, but with the US we're speculating".

"Any risk to [the US share] is just hugely worrying," Professor Pitman said, adding China is one nation rapidly expanding research although not fast enough to fill a major US retreat.
Ironically, it was China that Mr Trump earlier singled out to blame for the "hoax" of climate change.

"It's like driving in a tunnel and switching off your headlights - not a wise thing to do," Professor Timmermann said. "It has some elements of going back to a very anti-science, medieval mindset that is not only detrimental to the scientists but also the general public."
And as Professor Pitman noted, "the laws of physics don't change just because Trump has become president."
