Energy chief suggests Trump administration is altering previously published climate reports | CNN Wright said the Trump administration is updating the National Climate Assessments that have been previously published, which the administration recently removed from government websites.

The sharpie is out as facts are buried with revisionist zeal. www.cnn.com/2025/08/07/c...

Our daily weather forecast is under threat from Trump cuts to US climate agencies US President Donald Trump's proposed cuts to US weather and climate services will cause the loss of critical data Australia relies on for its weather and climate modelling.

Great article by Tyne Logan on the potential impacts of US cuts in weather and climate observations, research and modelling. But planning ahead will reduce the impacts.

Why a NASA satellite that scientists and farmers rely on may be destroyed on purpose The Trump administration has asked NASA staffers to draw up plans to end at least two satellite missions that measure carbon dioxide in the atmosphere, according to current and former NASA employees.

The anti-science Trumpers may be planning to destroy two working satellites that provide vital measurements about carbon dioxide & climate (and data that forecasts crop yield, drought conditions, & more). They cost $750 million to make but only $15 million/yr to operate.

Are you a top US-based scientist wanting to relocate to Australia? We are now calling for formal applications from both Australian and non-Australian citizens based in the US whose work is internationally recognised as exceptional.

As US climate data-gathering is gutted, Australian forecasting is now at real risk For decades, Australia has relied on data from US satellites, floats and monitoring programs. Planned deep cuts put Australian forecasting at risk

Europe is breaking its reliance on American science European governments are taking steps to break their dependence on critical scientific data the United States historically made freely available to the world, and are ramping up their own data collection systems to monitor climate change and weather extremes, according to Reuters interviews.

European governments are breaking their dependence on scientific data the United States used to make freely available, ramping up their data collection systems to monitor climate change & weather extremes. Now we’re just giving away our leadership positions.

Position Statementβ€”Australia’s scientific leadership in Antarctica Antarctic and Southern Ocean science is critical to understanding and responding to climate change and safeguarding Australia’s national interests.

We welcome the Australian Academy of Science’s position statement on Australia’s scientific leadership in Antarctica and the Southern Ocean.
It calls for urgent, ambitious, and strategic action backed by whole-of-government support and sustainable funding.

Opinion | Why U.S. dominance at sea is shrinking The U.S. still has an advantage on the waves, but ocean science needs more β€” not less β€” investment.

Read this from @pdemenocal.bsky.social, @msleinen.bsky.social, and John Richardson, retired Navy admiral, whose son was my student, about how investing in ocean science is not just about curiosity, but about ensuring our future readiness, resilience, and national security. 🌊

Worse than suppression: trying to wreck concerted action and in the process increasing climate change harm to humanity. The actions of a pariah state that needs to be excised and isolated.

Still trying to understand why there’s no mandate for including greens - but there is (apparently) for the rest of the cross bench??
Maybe some of the cross bench might see this as problematic for a representative democratic response.

Ha indeed!
At the very least, you’d think that the fear of calling another election would give the cross bench strong leverage. Of course, a way out would be for one major to have an (implicit?) support deal with the other!! Last at least long enough for some legislation and sod-turningβ€½

No majority for Lib/Lab and neither can get a compliant enough (non-green) X-bench agreement. Peter G|David O’B|Krisitie J offer to lead a cross-party cabinet, forcing a major to agree or be the pariah that sends state back to the polls (surely a death wish). Possible?

I’ve reconsidered your point, chastened - I had a hard look, and if I start with favourites with a decent chance, skip those who will already redistributed or have a quota, then *7* prefs works!
Beyond that there’s literally nobody I care about getting my residual vote so exhaust is ok.
