“Tamboran…donated $169,500 to both sides of politics ….Tamboran Resources plans to sell fracked gas to the NT government, and develop a major LNG project at the Middle Arm Sustainable Development Precinct in Darwin, which has been allocated $1.5 billion in equity by the Federal Labor Government.”
“Australia’s largest oil and gas company, Woodside, donated $53,775 to the Australian Labor Party and $40,140 to the Coalition prior to the 2025 Federal Election. Just 25 days after the election, the government conditionally approved extending the company’s North West Shelf LNG plant out to 2070.”

Bottom line: Don’t confuse “hard” with “obsolete.” The world doesn’t need permission to lower ambition. It needs governments to implement what they already agreed—at the speed and scale that 1.5°C demands.
The pursuit of 1.5°C endures as a legal and ethical imperative in a changing world
As the world nears 1.5°C of global warming, near-term emissions reductions and adequate adaptation become ever more important to ensure a safe and livable planet for present and future generations
www.science.org
As @joerirogelj.bsky.social put it "the PA’s goal to pursue efforts to limit global warming to 1.5°C therefore endures as the legal and ethical imperative to secure a safe and livable planet for present and future generations."

And let us not forget that the Paris Agreement’s 1.5°C warming limit remains the world’s enduring legal, political, and moral anchor for climate action – abandoning it would only deepen injustice for vulnerable communities already bearing the brunt of climate change.
In all this that should not be forgotten that since 2015, the Paris Agreement has provided quantified targets at national and global levels consistent with limiting warming as close as possible to 1.5°C.
Whilst “Clean-energy shift” can be a useful slogan it can’t replace the temperature limit and by itself generate the time bound actionable targets needed to protect us from dangerous climate change.
The Paris Agreement provides the basis to design critical clean energy benchmarks to limit overshoot as low as possible and get warming back below 1.5° by 2100. Without the 1.5C limit it is unlikely that the right benchmarks would be calculated or chosen.
On geoengineering: the push for risky interventions grows because of delayed action not because of the 1.5oC limit. The answer is not to abandon 1.5°C—it’s to act fast enough so we don’t drift into an “anything goes” approach unguided by what we need to protect ourselves from and call it pragmatism.
This scenario shows the time bound actionable targets needed globally to strictly limit overshoot and reduce warming below 1.5° by 2100. For example, renewables capacity needs to grow significantly, with a 3.5-fold increase by 2030 – ahead of the global tripling goal agreed at COP28.
In terms of a clean energy shift this highest possible ambition scenario shows that global electricity generation needs to quadruple by 2050, with wind and solar supplying over 90% of electricity demand by then. Fossil fuels would be effectively phased out shortly afterwards.
This work shows how to minimize overshoot and return to well below 1.5°C by 2100 with renewables, electrification, efficiency, methane cuts, deforestation reduction—reaching net zero around ~2060 if governments deliver.

With colleagues at @pik-potsdam.bsky.social using the Paris Agreement's climate goals we have looked at what can be done using the highest possible ambition to absolutely minimise overshoot of 1.5°C and to get warming back below 1.5° by 2100.

These climate targets provide the tools to design the critical time bound benchmarks for a clean energy shift to limit overshoot as low as possible and get warming back below 1.5° by 2100. Without this framework there is not real anchor for these benchmarks.

Overshoot management isn’t “wait until 2100 and see,” as the article suggests.
The Paris Agreement climate goals provide the indispensable scientific basis for what benchmarks for clean energy, energy efficiency, methane reductions and deforestation action are needed and by when.

We all agree we need actionable targets to guide policy.
But here is the big thing: The Paris Agreement’s climate goals - the1.5oC limit and net zero in 2nd half of the century - provide the essential and critical legal and scientific basis for what clean energy targets are needed and by when.

First: yes, we’re heading into overshoot @wmo-global.bsky.social 1.5°C in the next 5 years. This is not a geophysical accident. It is the result of policy failure. Now what's needed is action to limit the magnitude and duration of overshoot to drive temperatures back down.

As we breach 1.5 °C, we must replace temperature limits with clean-energy targets
Actionable goals are needed to guide the world towards what needs to happen most quickly: shifting economies to clean energy sources.
www.nature.com
A commentary in @nature.com argues the 1.5°C temperature limit has “outlived its usefulness” because we’re headed towards overshoot and should be replaced by a “clean-energy shift” metric. That’s the wrong diagnosis. Here is why.

Federal Labor's light touch environmental review of a massive new fracking industry threatens one of Australia’s most iconic wild places – and blows out national emissions.

It's difficult to fathom what the WA Envtl "Protection" Agency doesn’t understand abt the climate problem. Wilfully & deliberately authorising a massive gas development in this pristine environment must only be viewed as institutionalised climate denial.

Last year, the world added a record 582GW of #renewables energy capacity. That’s over 91% of all new power – with #nuclear nowhere. In fact, each year, nuclear adds as much net global power capacity as renewables add every two days.

After COP30, it is now up to national leaders to close the gap between promises and reality.

As COP30 comes to a close, read the statement from CA CEO @billhare.bsky.social. This COP did not deliver the bold fossil fuel phaseout roadmap needed, but it did nudge other goals forward.
National leaders must now close the gap between promises and reality.
