Mmmmm… Who to believe on climate change impacts on Australia over the coming century? Australian peer review published climate scientists from BoM and CSIRO inc. several IPCC and WMO experts, or, The Daily Mail. I had to reassure myself it wasn’t 1 April. #dinosaurs

Aboriginal and Torres Strait Island Peoples will face many and unique risks from climate change, while also having knowledges that can contribute to adaptation. Great NITV/SBS article on the 7 specific ATSIP risks in the National Climate Risk Assessment #NCRA www.sbs.com.au/nitv/article...

This interview with Bill Hare on Australia’s first climate risk assessment is so good, I made a transcript. Please feel free to read and share: docs.google.com/document/d/1... Thank you @billhare.bsky.social

You think you can get the truth from this party or that party or some podcast or pundit. But the people who tell the truth are called actuaries.

Our kids will not only have unaffordable mortgages, but also unaffordable home insurance (which actually means they can’t get a mortgage). Bugger. #NCRA www.bloomberg.com/opinion/arti...

After years of complaining about cancel culture, the current administration has taken it to a new and dangerous level by routinely threatening regulatory action against media companies unless they muzzle or fire reporters and commentators it doesn’t like.

These are precedented times and the precedent is a loud ass warning www.nytimes.com/1939/02/04/a...

Bill Hare @billhare.bsky.social - climate scientists and former IPCC Leas Author - says the recently released Australian NCRA **is one of the best risk assessments done globally** “a very fine piece of work” He’s far less enthusiastic about political silly statements www.abc.net.au/listen/progr...

This is powerful commentary and clear logic from @richarddenniss.bsky.social

🌊 “The fact that 1.5 million Australians may be impacted by rising seas and coastal hazards by 2050 is shocking, even for this sea level scientist.” — Prof Matt King @deformedearth.bsky.social @antarcticsciaus.bsky.social @utas.edu.au ▶️ aappartnership.org.au/antarctic-sc...

“The average amount of water flowing into Perth dams has reduced by a whopping 80 per cent over the past 50 years.” Great explainer of the drying out of Perth and other ‘Mediterranean’ climates around the world. www.abc.net.au/news/2025-09...

This is just climate vandalism. Our future generations will hate us for our stupidity. Goodbye to 1.5 - was nice being hopeful for a while there. www.theguardian.com/environment/...

Jan-Jun 2025 streamflows into Melbournes Dams have been *lowest on record* (records start 1913) with streamflow ~half of 2024 levels. Storage volumes at lowest levels for winter since 2020.

"Is climate action a net cost or benefit? To date, the most detailed analysis in both Australia and the United Kingdom give the same answer: when the escalating damage done by climate change is accounted for, climate action has vastly more benefit than cost." theconversation.com/rapid-climat...

Impressive satellite image as a weak surface low in the bight with substantial upper low approaches #NSW . The link to the very warm eastern Indian Ocean is clear in the moisture in-feed @bom.gov.au .

Last month was the 3rd warmest August on record for the average global sea surface temperature (SST)... Graphic using data from NOAA ERSSTv5 (psl.noaa.gov/data/gridded...), with methods described in doi.org/10.1175/JCLI...

August 2025 was the third warmest August on record after 2023 and 2024 at approximately 1.3C above preindustrial levels. This continues a string of recent months a bit cooler than the exceptional 2023/2024 temperatures but warmer than any prior years.

The climate crisis will continue making lightning-sparked wildfires more frequent for decades to come — putting public health, forests, and communities at greater risk. My latest for @theguardian.com, quoting experts from @uofcalifornia.bsky.social: www.theguardian.com/us-news/2025...

Calculating the costs to business of net zero WITHOUT including the costs of climate disaster or green economy profits is like saying “It will cost me big time to stop getting punched in the face” without mentioning the benefits of not getting punched in the face. www.theguardian.com/australia-ne...

The contrast between the EU (eg ECMWF) and the US has never been more stark. The US looking to cut funding for an AI weather forecast research group when the rest of the world is making giant leaps forward in the same space. #nosesandfaces www.nbcnews.com/science/scie...

A55% chance of meeting the weak US definition of La Niña in Sept-Nov. Press release is way too emphatic for something that would barely meet LaNina WATCH if BoM was still doing it. Negative IOD however is driving more rain at present in Australia. wmo.int/news/media-c...

The S.A algal bloom “began when rising water temperatures killed kelp, seaweed and macro algae that preferred cooler waters. The effect was to mulch the sea floor with organic matter that … was heaven for dinoflagellates … that includes Karenia mikimotoi.“ drilled.media/news/algal-b...

I can’t claim to be a Dunning-Kruger expert, but this would appear to be a poster child for the far left of the curve (where the stoopid + overconfident lives).

If you were a user or admirer of NOAA’s amazing climate.gov website - which has had all the good stuff (e.g., actual data and climate monitoring indices) removed by government - some web and data gurus/guerrillas are about to launch a recreation at climate.us. Follow @climate.us for launch updates.

We looked at impacts of a shutdown of the AMOC on Australia in our Tipping Points workshop report for the National Climate Risk Assessment. Unlike N.Hem, it may enhance warming in the S.Hem/Australian region, and could induce a La Nina-like wetting of northern Australia www.csiro.au/-/media/Envi...

The American Meteorological Society has issued a statement about the US Dept. Energy (climate sceptic) report on climate change. TL:DR "WTF!" (couched diplomatically) . www.ametsoc.org/ams/about-am...

Dry areas of SA and Vic, plus high fuel growth areas in northern WA, are at higher than normal fire risk entering Spring. Overall, a reasonably benign spring fire outlook for the nation. Bushfire outlook for spring from AFAC, BoM and State & Territory fire agencies. www.afac.com.au/public-resou...

BoM seasonal outlook for spring. Warm local seas and negative IOD driving a wet outlook. “There is an increased risk of flooding during heavy rainfall on the east coast of New South Wales and south east Queensland following a wetter than usual year in these regions.” www.bom.gov.au/climate/ahead/

Congrats to Australia’s Prof. Todd Lane and Dr Peter May for being elected as Fellows of the American Meteorological Society. Plus of course a whole bunch of amazing others. www.ametsoc.org/ams/about-am...

My latest: The Trump administration is not waiting for the next fiscal year -- or Congress -- to cut climate science at NOAA. A new document details the money it won't spend *this* year on climate research.

“The spending plan makes clear the particular animus the Trump administration has for climate research. In 2024, NOAA spent $219 million on climate research; this year … the agency will spend $165 million—a drop of $53 million, or 25%” Simply ignoring Congress www.science.org/content/arti...
