What do we know about climate change? How do we know it? And where are we headed? Cimate scientists are more certain than ever that humans are changing the climate – but there are signs of hope on the horizon.

In this article @adisen99.bsky.social and I take stock of where the Earth's climate is at and where we're heading. Climate action has never been more critical #COP30 theconversation.com/what-do-we-k...

The results challenge claims that the climate risk posed by an individual projects is negligible or cannot be quantified.

Quantifying the regional to global climate impacts of individual fossil fuel projects to inform decision-making - npj Climate Action npj Climate Action - Quantifying the regional to global climate impacts of individual fossil fuel projects to inform decision-making

For so long, fossil fuel projects have said their contribution to climate change is "negligible".
Turns out that's wrong.
Our research in NPJ Climate Action proves it.
Every tonne of CO2 matters.

Don’t let anyone fool you into thinking carbon dioxide removal is the solution to climate change.

It’s a small piece of the puzzle. But it won't be able to offset a substantial portion of our fossil fuel emissions 🧵

The people I work with are not stupid people and our climate predictions of 30 years ago of global warming have proved to be accurate. Just saying. www.bbc.co.uk/news/live/cp...

The fix is in Judy Curry unwittingly spills the beans

On The Climate Brink: More about the DOE Climate Working Group report.

The Fix Is In: Without independent review editors, their “peer review” process is a sham. Science and humanity deserves better.

Dozens of scientists find errors in a new Energy Department climate report More than 85 scientists say that a recent U.S. Department of Energy report is full of errors and misrepresents climate science.

More than 85 scientists say that a recent U.S. Department of Energy report is full of errors and misrepresents climate science.

The DOE Climate Report is full of misleading claims and cherry-picking as demonstrated in this meticulous report. I'm happy to have played a small part in this community response.

To put it bluntly, Australia needs to up its game on emissions reductions. Globally we'll need to achieve net zero to halt global warming and even then Australia and the Southern Ocean may continue to warm for some time to come.

We need to get to net zero ASAP.

This report shows what targets Australia should adopt to align with the 1.5°C Paris Agreement goal that Australia has signed up to. For Australia to be playing its part it would need to strengthen the 2030 target and achieve at least 81% emissions reduction (relative to 2005 levels) by 2035.

Changes are brewing in the Indian Ocean. Does this mean Australia should get ready for a soggy spring? What do the next few months hold, weather-wise? For clues, we can look to the oceans around Australia.

I take a look at how spring is shaping up for Australia and the possible negative Indian Ocean Dipole event taking shape theconversation.com/changes-are-...

Lots of news articles today about recent cold weather and the cold July in parts of Australia, e.g. www.abc.net.au/news/2025-08.... It's worth noting though that it was still warmer than historical (1961-1990) averages even in Western Australia which had its coldest July since 2012

Interdisciplinary challenges for wildfire futures Wildfire has shaped many ecosystems across Earth, and humans have in turn shaped fire and its interactions within a range of socio-ecological systems.…

New paper out! This is a big, interdisciplinary reflection on the types of challenges that are likely to come our way in the context of wildfires in the next 50 years. Was fun to write this one. authors.elsevier.com/sd/article/S...

I think also there's a lot of misunderstanding in the report of how science works. It's expected that studies will build on each other and statements revised as knowledge grows.

A great summary of a report with so many holes and so much cherry-picking it's hard to know where to begin! Thanks @benmsanderson.bsky.social

The flooding of the Guadalupe River in Texas was undoubtedly made worse because of climate change. I would estimate that there was 7-20% more rainfall than w/o the human interference in the climate. But w/o detailed attribution studies on the storm and associated runoff, we can't know for certain.

Enhancing communication of climate changes under net zero emissions - Communications Earth & Environment Much of the public discourse around climate changes under net zero carbon dioxide emissions has been focused on global mean temperature changes after emissions cessation. More attention needs to be pa...

In our new paper we discuss how communication of post-net zero climate changes needs to improve and go much further than global average temperature @chrisd-jones.bsky.social @sarahinscience.bsky.social @21stcenturyweather.bsky.social www.nature.com/articles/s43...

⚠️ Scientists urge eastern Australia to plan for more dangerous floods as climate warms

A rapid study by @wwattribution.bsky.social found the wettest 4-day rainfall events in a year are about 10% more intense in NSW compared to the preindustrial climate 🧵

Here’s a quick summary (1/n) 🧵

NSW is copping rain and flooding while parts of Australia are in drought. What’s going on? In some areas of NSW, more than 200 mm of rain has fallen in 24 hours. At the same time, dry conditions have gripped much of the continent.

Australia is experiencing both severe flooding from record rains and a significant drought at the same time. Andrew Dowdy and I take a look at what's happening theconversation.com/nsw-is-coppi...

Well done to PhD student Liam Cassidy on a new paper examining projected changes in heat extremes under net zero CO2 emissions and causes of uncertainties at the regional scale. agupubs.onlinelibrary.wiley.com/doi/full/10....

It’s almost winter. Why is Australia still so hot? Why is it so warm across southern Australia this autumn? Where’s the rain? ‘Blocking’ high pressure systems are to blame, but the real culprit is climate change.

Much of Australia is having a remarkably warm autumn. Here I discuss the main drivers of the unseasonable heat and what's in the outlook. theconversation.com/its-almost-w...

Large-scale greenhouse gas reductions will take time to return most of Earth to pre-industrial climates, a study in #AMSJCli suggests. Several decades later, only a few areas are likely to “de-emerge” say authors @hunterdouglas.bsky.social, @andrewkingclimate.bsky.social et al.

Scientific diagram summarising the causes of drought development, intensification, and termination in Australia. The graphic shows that drought development and intensification is associated with El Nino and positive IPO conditions in the Pacific Ocean, positive IOD conditions in the Indian Ocean, reduced onshore moisture transport, high pressure systems over south-eastern and south-western Australia, dry MJO phases, and wind-evaporation feedbacks - with all affected by anthropogenic forcing. Drought termination is associated with La Nina and negative IPO conditions in the Pacific Ocean, negative IOD conditions in the Indian Ocean, enhanced onshore moisture transport, cut-off low weather systems in south-eastern Australia, monsoon lows in north-western Australia, and wet MJO phases - with all affected by anthropogenic forcing.

Out today: our comprehensive review of Australian droughts.

It covers the nature and drivers of drought development, intensification & termination - and how those are changing with climate change.

Although global mean temperature has cooled down slightly with respect to March 20th, it's now three days in a row (March 20th- 22nd) with unprecedented record temperatures for those days of the year 🌡️🌍🌊
