How can Australia convince the world to give up fossil fuels if Anthony Albanese is contradicting himself on gas expansion? | Bill Hare Getting to net zero CO2 emissions globally means we can halt global warming. This requires a rapid phase-out. It’s physics With another set of global climate talks behind us, the Australian government faces some tricky tasks before it takes over negotiations at the next round of talks next year in Turkey. Cop30 in Belém, Brazil, did not deliver the bold fossil fuel phase-out roadmap we needed, but it did nudge the system forward with more scrutiny of fossil fuel producers. And despite the weakness of the outcome, one can gain some important comfort by the fact that Bélem – and the G20 in Johannesburg at the weekend – both solidly endorsed the Paris agreement, its central goal of keeping warming to 1.5C and the importance of net zero emissions. Cop30 agreed that an “ambition accelerator” will be needed to fill the gap between what governments are planning (projected to warm the world by 2.6C) and the agreed guardrails of the Paris agreement: a limit of 1.5C. It also, crucially, began the momentum for developing a roadmap for a just transition away from fossil fuels, with more than 80 countries – including Australia – signing the “Belém declaration” on a transition away from fossil fuels. While this declaration didn’t get support from the whole conference, Brazil’s president, Luiz Inácio Lula da Silva, has promised to move forward on its implementation during the course of this year, until he hands over to Cop31 in Turkey.

Bill Hare, CEO of Climate Analytics, comments at the end of COP30 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.

REPORT: If governments were to implement the promises they made in 2023, to triple renewables, double energy efficiency, reduce methane by 2030 & beyond, they could
✅ significantly cut projected warming - by 0.9˚C
✅ cut warming rate by a third by 2035 and halve it by 2040

CSIRO to cut up to 350 research jobs in major overhaul After 440 positions were slashed last year, the CSIRO has announced more staff cuts across the country in a bid to remain financially viable.

Where to start, with a statement like this?

"Tim Ayres said the cuts were aimed at refocusing … CSIRO towards research priorities, such as critical minerals, iron & steel production in Australia."

From some rando down the bus stop, one would brush it off.

But this is from our Science Minister 🤯

Will Labor’s environment laws actually address Australia’s biodiversity crisis? Five reasons to be concerned Experts say the proposed legislation is full of problems, including excessive ministerial discretion and relaxing like-for-like offset rules

There is increasing evidence that the Albanese government proposed changes to Australia’s in environmental assessment legislation could go backwards rather than forwards, in terms of environment, biodiversity and climate protection.

New research out today demonstrates that reaching #realzero is achievable and economically competitive in many major emitting sectors.

EU road freight could reach real zero by 2040, while global steel and shipping could reach real zero by 2050.

What we have seen in the last few years is many countries, including very rich ones such as Australia, Qatar, Norway, UAE, USA, support massive new development of fossil fuels notably oil and gas. Unless this stops the world will literally cook.

The next few years are going to be critical in deciding whether the world can avoid the worst global warming damages, or lock in escalating damages. In this context the upcoming UNFCCC COP30 in Brazil is the most important since the Paris Agreement was adopted in 2015.

We can stop global warming by midcentury if we reach global net-zero CO₂ by 2050
Every year above 1.5°C raises the risk of crossing tipping points—irreversible ice loss, shifts in ocean circulation, ecosystem collapse, increasing economic damage due to heat, flooding, more intense storms.

This means immediate, sustained emissions cuts across all sectors, rapid phase-out of fossil fuels. Countries need to stop using forests to “offset” fossil fuel emissions. We have never been in a better position to achieve this due to rapidly reducing costs of renewable power

Getting back well below 1.5°C before 2100 is still possible, but only if we act now to peak global warming as close as possible to 1.5˚C and minimise overshoot to reduce chance of crossing tipping points and to avoid catastrophic damages.

Yesterday, the UN SG António Guterres said the world has failed to prevent overshoot of 1.5°C of warming, the Paris Agreement limit.

This is a massive political failure.

Urgent action is needed now to limit the magnitude and duration of overshoot.

Is "hard-to-abate" really that hard - or is it a justification for delay? Labelling heavy industry like steel as "hard-to-abate" has shaped policy and business action in ways that risk undermining global efforts to cut emissions

Labelling heavy industry like steel as “hard-to-abate” allows them to argue against reducing emissions now, or to justify using CCS or offsets to meet climate goals.

But existing tech and demand reduction can cut emissions in these sectors, writes @billhare.bsky.social on
