And if for whatever reason you omit any information such as a disused account, old phone number, etc. you have made a false declaration. The experience of others so far demonstrates the high risks of being subject to mistreatment with few protections and uncertain outcomes.
Why go? Why risk it?

MYIC DCN camp, aerial view. Traverse vehicles and vans are seen alongside vans for amenities and sleeping and the new kitchen and mess shelter. The large drill tent is seen at the far right.

The past week has been busy as the station infrastructure is installed, providing kitchen and amenities buildings independent of the traverse facilities. Camp with newly constructed kitchen and mess in the centre. πŸ“· D. Beloin /..

Activity at the Dome C North station is fully underway with the final placement of camp infrastructure and science drilling commencing. The first drilling task will be installation of 120 metres of casing in the upper borehole. πŸ“· J. Pedro /1

Had one die in an inaccessible closed off chimney 🀒 Truly awful, but capped off in horror as a phalanx of fat stinky maggots emerged some time later from every nearby crevice.
Bolted the replaced chimney cover down so tight that no creature could prise it off.

It surely also compromises the ability of the accused to manage a legal defense in any number of ways consequent to loss of income.

Two billion kids would REALLY appreciate it if we did more about this than just make a few non-binding promises every year & then instantly forget about them.

You are right that Australia should sign on to the MutirΓ£o roadmap. It’s not enough to state reductions goals, we need a roadmap and more. We urgently need to already be travelling the road to serious phase-out.

Read this interview with @peterthorne.bsky.social to understand how dire the situation is with respect to US science funding. The US has played an outsized role in Earth observations and global coordination, and even if other nations decide to step in, it would take at least a decade to recover.

If such abject failures, verging on deliberate corruption, have inadequate penalties then there’s little point in standards and regulatory oversight.

The Coalition is spinning a lie that climate action is economically bad. How are they getting away with it? | Zoe Daniel In this post-truth environment, the interests of coal and gas are somehow able to win the hearts and minds of voters * Get our breaking news email, free app or daily news podcast During the last parliament I negotiated an amendment to the Climate Change Act to lock in Australia’s carbon emissions target as a floor – not a ceiling. I did it to promote government ambition to exceed the target and, having covered the first Trump administration’s withdrawal from the Paris agreement, to provide a legislative buffer against backsliding by a future Australian government.

This is good communication - a simple message clearly articulated. The fossil-ocracy arguments around affordability are distortions of reality.

They don't care if it is solved so much as that they profit from it.

Long haul for science begins – Australian Antarctic Program (News 2025) Australia’s Antarctic tractor-traverse team is making its way up the Antarctic plateau to deliver scientific equipment, fuel and food to the site of the Million Year Ice Core (MYIC) drilling project.

Our season is now well and truly underway with the traverse climbing toward the drill site on the plateau. www.antarctica.gov.au/news/2025/lo...
