Nature Climate Change has an online collection of reviews, opinion pieces, and research on climate change communication.

Climate change communication

Effective climate change communication enhances public climate mitigation and adaptive behaviour, building resilience against intensifying climate hazards.

The missing words in the climate conversation are not human-caused climate change, but fossil fuel emissions. By Hayley Fowler and myself: theconversation.com/was-this-hea...

‘Was this heatwave caused by climate change?’ – we’re asking the wrong question

Instead of asking whether climate change caused a heatwave, we should ask how much hotter it became because of fossil fuel emissions.

Successful first week on the #RVInvestigator in the Sourhern Great Barrier Reef 🪸. Lots of samples and data - great team, and lots of great science. Everyone finally over their sea sickness. 🌊🐋

The IMF says we pay $5T/year to subsidize fossil fuels — that's $13M per MINUTE to destroy our future. Meanwhile solar & wind fight for scraps. We don't have a funding problem. We have a priority problem.

Excited to set sail on the big blue ship (#RVInvestigator) today after years of planning this voyage with the traditional owners Darumbal and neighbours Woppaburra to study the submerged landscapes and the oceanography of their sea country. Nice send off - a smoking ceremony by tribal experiences.

25 tonnes of nurdles, more than 1 billion nurdles, were spilled into the Tyne last week and are washing up on our beaches, north and south of the Tyne. Likely one of the largest ever plastic pollution events in the UK. There is remarkably little mention of this on here.

🌊 ANTARCTIC SCIENCE, AUSTRALIA'S FUTURE The exciting program for #AARC26 is out, with more than 300 people coming to our national conference in August. There are still places available if you'd like to attend. Registrations close 28 July. Program ▶️ leishman-aarc-2026.eventsairsite.com/program

When wildfires, floods or heatwaves strike, the question isn’t “Did climate change cause this?” It’s “How much worse did climate change make it?” theconversation.com/how-do-scien...

Australian scientists are exploring ways to remove carbon from the atmosphere – using our oceans.

Can we alter ocean chemistry to absorb carbon? Here are the pros and cons

Great Barrier Reef microbiome mapped as researchers discover 500 bacterial species previously unknown to science

Research identifies 808,585 viral genomes belonging to what scientists estimate to be 362,802 different viruses

New work led by @stevenjrobbins.bsky.social @markoterzin.bsky.social finally published - we now have a reference of microbial genomic resources from the Great Barrier Reef. The paper came out just hours after the work presented by Marko at #ICRS2026 @icrs.bsky.social See thread here for more detail

It's out! Excited to present the Great Barrier Reef Microbial Genomes Database (GBR-MGD), a comprehensive DB of 1000s of high-quality prokaryote, virus, plasmid, and chromosome-level eukaryote MAGs using Nanopore long reads. Subthreads incoming. Please share widely. 🙂 www.nature.com/articles/s41...

A new catalog of deep-sea microbial genes, built from 2,138 samples, added 502 million genes and expanded known ocean gene diversity by 51%. The authors call the deep sea "a unique evolutionary engine driving the emergence of functionally distinctive enzymatic traits." #marinelife

Exciting anniversary present from my husband - 2 days before heading out to sea for my next research voyage. Hope we don’t need it on the ship…

Why look to Mars when Earth hides animal ecosystems thriving 9,533 meters deep in the Pacific hadal zone, under over 900 times surface pressure? Our own planet is astounding!

Scientists discover the deepest animal ecosystem ever found, thriving nearly 10 kilometres beneath t

Scientists have uncovered the deepest known animal ecosystem on Earth, thriving almost 10 kilometers beneath the Pacific Ocean, challenging previous assumptions about life at such extreme depths. Dens

Plastic particles are found throughout the ocean, from the surface to the deepest trenches. But the lack of consistent methods for studying these particles hinders understanding of their movement and consequences. eos.org/features/mea... Read more in our July issue: eos.org/themes/micro...

Small bits of plastic don’t just float at the sea surface—they span the entire water column. Scientists need consistent methods to track these particles and to better understand the hazards they pose.

Great Barrier Reef faces ecological collapse as El Niño looms

This, scientists warn, is a signal that urgent global systemic change is needed to prevent the widespread loss of our critical ecosystems

The ARC's new grant scheme table, in case you don't want to read through the details (which are here: www.arc.gov.au/system/files...)

ARC Tracker@arc-tracker.bsky.social · 2w ago

The ARC has released their new set of grant schemes ▶️ www.arc.gov.au/news-and-pub... Before implementing them, they’re now going to “consult with the sector”. Hopefully genuinely, not just with a few disengaged DVCRs. In the meantime, there’ll be another round of Discovery Projects (DP28).

Oxygen "disappearing" from earth's waters at alarming rate

Scientists warned that low oxygen levels threaten entire food webs, and the phenomenon should be recognised formally in climate frameworks

Oh no. Another giant of climate science, oceanography, and understanding the carbon cycle has left us. Jorge Sarmiento was a true giant in the field, and a dedicated mentor to countless students over the years. The entire field owes him a great deal. www.princeton.edu/news/2026/05...

Remembering Jorge Sarmiento, a ‘giant’ in climate studies

Climate scientist Jorge Sarmiento was Princeton's George J. Magee Professor of Geoscience and Geological Engineering, Emeritus, and a professor of geosciences, emeritus.

The super El Niño is likely to have a major impact on the Great Barrier Reef 🪸 - given the last few El Niños were linked to large bleaching events. We won’t save the GBR unless we start to tackle climate change.

"If you were on a big boat, like the Titanic, & someone comes up to you & says the boat's going down, you bloody well get on those lifeboats & start acting & do stuff" "We're not doing that. The ship is starting to sink in a really massive way, & we're not seeing it as what it is. It is so serious"

Apparently the "boring billion" was actually exciting! We provide molecular evidence of complex Mesoproterozoic eukaryotic communities. So happy to see this out 🥳 Thanks to @phoebefossil.bsky.social , Hélène Morlon & @fburki.bsky.social for a lovely collab! doi.org/10.1073/pnas...

Quite a remarkable picture of ocean warmth when looking at last month's sea surface temperature anomalies globally. El Niño of course looks more visible, but there are plenty of other hotspots (including at the map edge, like in the Mediterranean Sea). Data from www.ncei.noaa.gov/products/opt... 🌊
