Here's how the records stacked up during the recent heatwave over central and southern Australia. All-month maximum temperature records at individual stations with 25+ year histories are highlighted.

Pooncarie in western NSW had a maximum temperature of 49.7 °C on Tuesday - equal second highest on record in NSW. Menindee recorded the same value and Wilcannia reached 50.1 °C in January 1939.

Victoria has officially recorded its hottest temperature ever in the town of Hopetoun in the state's north west.

At 4.04pm this afternoon, Hopetoun's temperature soared to 48.9ºC, beating the previous record of 48.8ºC in the same town during the Black Saturday bushfires.

This is climate change.

Current temperatures in the Mallee are the highest ever recorded in VIC. Several long-term, all-month temperature records have been broken at stations across southern Australia on Monday and Tuesday, with the heatwave ongoing in the east.

For 50 years, global warming had a very consistent trend (+0.19 °C/decade) with a boring, predictable range of natural variations around it.

During the last three years, we've broken out above that range, suggesting the pace of change has quickened.

Trump on Greenland: If we don't do it the easy way, we're gonna do it the hard way. By the way, I'm a fan of Denmark. The fact they had a boat land there 500 years ago doesn't mean they own the land. We'll be doing something with Greenland—the nice way, or the more difficult way.

For the eighth year in a row, the world’s oceans absorbed a record-breaking amount of heat in 2025. It was equivalent to the energy it would take to boil 2 billion Olympic swimming pools. www.wired.com/story/the-oc...

📢Global Carbon Budget 2025📢

Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength.

The key findings are covered in two reports this year:
* ESSDD (preprint): essd.copernicus.org/preprints/es...
* Nature: www.nature.com/articles/s41...

I know I've said this before, but from advertorials to false equivalence the media really needs to own up to its role in warping the climate issue. www.thenation.com/article/envi...
The Media Is Complicit in the Climate Confusion
The vast majority of people want their governments to take climate action—but most wrongly think they’re in the minority. The media is partly to blame.

This is how the total greenhouse gas forcing changed over the past 130,000 years, relative to 1750 and converted to CO₂.

We've ain't seen nothing yet!

“This is the largest increase since modern measurements started in 1957 and is well in excess of the 2022–2023 increase of 2.3 ppm.”

Global carbon sinks buckling as pollution overwhelms Earth’s capacity to absorb our impacts. ☠️

CO2 levels in Earth's atmosphere jumped by a record amount in 2024
The global average concentration of CO2 surged by 3.5 parts per million to reach 423.9 ppm last year, fuelling worries that the planet’s ability to soak up excess carbon is weakening
