New analysis by @ember-energy.org showcases the transition from fossil fuel to clean energy being fast tracked in India compared to China and the Global North. This transition in the developing world will play a big role in determining our GHG emissions pathway in the 21st century.

La Nina + neg IOD = cold Australia, right? Not anymore. Just released: "2025 was Australia's 4th warmest year since national temperature records began in 1910. For Australia as a whole, the national annual average temperature was 1.23 °C above the 1961–1990 average" www.bom.gov.au/climate/curr...

2 new papers by Cooper, Armour & co use past climates, from the Last Glacial Maximum 21,000 yrs ago & the Pliocene 2.6-5.3 million yrs ago, to infer that the planet will warm about 3 degrees C for a doubling of CO2 as a best estimate for present day. doi.org/10.1126/scia... doi.org/10.1073/pnas...

One advantage of transferring the legacy SSP web database to the new #ScenarioServices infrastructure... You can can now query SSP scenarios directly via the #python package #pyam_iamc 🎉 Check out the tutorial at ssp.apps.ece.iiasa.ac.at/documentatio... github.com/iamconsortiu...

With ongoing climate negotiations at COP30 in Brazil, here is a brief primer written by @andrewkingclimate.bsky.social and I on the strides we have made to improve our understanding of Earth's climate and its changes. Now we need ambitious climate policies!!! theconversation.com/what-do-we-k...

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...

It was a pleasure to be involved in this. Not a pleasure that it was necessary, but seeing around 80 scientists come together to defend scientific integrity, led brilliantly by Andrew, filled me with pride.

📑 The first IPCC Assessment report came out in 1990. Prior to 1990, most parts of the world had already seen an increase in regional temperatures. Post 1990, regions with a high Human Development Index have seen the rate of warming increase. agupubs.onlinelibrary.wiley.com/doi/full/10....

www.economist.com/interactive/... This very insightful recent article in Economist tackles the topic of the delicate balance in aerosol pollution and GHG induced warming, and this balance is critical in developing regions in South Asia.

After the March 2021 floods, which had a similar pattern of unrelenting moist air over the east coast and a cut-off low, we quantified how likely these events may be in the future.

Wrote a short piece for Indian readers who often think reducing air pollution will reduce climate impacts, also featuring @adisen99.bsky.social's paper. Many were shocked, and it started conversations on why India is surprisingly cool with ~0.7 °C of total warming! www.thehindu.com/sci-tech/ene...

Have you wondered what causes Australia's droughts? Why sometimes the expected rainfall just doesn't come? Our newly published review explains! Read the full article here: rdcu.be/eeZHX

Fascinating paper by @ccrc.bsky.social “Damage to world GDP in 2100 under SSP5-8.5 increases from ∼11% under models without global weather to ∼40% if global weather is included. Further … welfare-optimal amount of climate changes from ∼2.7C to ∼1.7C.” dx.doi.org/10.1088/1748...

Australian coral reefs are currently ranging from 'bleach watch' to 'bleaching and most dying' categories. Be nice to see at least one 'no stress' sight, but hey... www.theguardian.com/environment/...

Scenes from the incredible turnout today at Berkeley's @standupforscience.bsky.social rally. @tedmiguel.bsky.social, @jenniferdoudna.bsky.social, and dozens of researchers, elected officials, and citizens defended science and the jobs, health benefits, and progress it creates for all Americans.

Onshore intensification of subtropical western boundary currents in a warming climate Inducing warming that worsens coastal marine heatwaves, reduces the ocean's capacity to absorb CO2, and destabilizes methane hydrates on the sea floor www.nature.com/articles/s41...

Science is necessary, but clearly not sufficient, for conveying the climate crisis https://go.nature.com/3XjoJCU

As extreme weather and the cost of energy dominates the headlines, knowing how to separate fact from fiction is more important than ever. Check out this week’s Changing Climate’s article tackling some of the fishy information out there: bit.ly/changing-climates-articles

Ocean has been losing its SST damping capacity (see Figure) since 1982 due to increased stratification, allowing SST anomalies and the associated climate and extreme weather events to attain stronger amplitude and persist longer. 🌊🧪 www.nature.com/articles/s41...

Look for the good news when you can. ☀️

If Australia wants to keep pace with other countries (let alone be a leader in science and innovation) then clearly this needs to change. www.abc.net.au/news/2025-01...

The impact of ENSO on regional rainfall is nonlinear, which can have a severe impact on regional hydroclimate variability. In this new paper with @andrewkingclimate.bsky.social and @drjobrown.bsky.social, we assess CMIP6 models in capturing this nonlinearity - doi.org/10.1029/2024...

As relevant to the current fire situations, this new research highlights that in California *and* eastern Australia, we might swing more often or more intensely,from wet to dry. Such swings produce more dry fuels for fires. Bummer. For both. www.nature.com/articles/s43...

The ice at Santa's workshop is thinning away... #NorthPole 🎁🧑‍🎄 Check out my blog from November 2022 for more on this graphic: zacklabe.com/blog-archive...

New paper @natclimchange.bsky.social finds that humid heat during the 2024 Hajj pilgrimage neared human tolerance limits. Analysis (by the Lethal Humidity Council, including CCRC’s Steven Sherwood and Katrin Meissner @katrinmeissner.bsky.social) warns further warming would threaten more people.

We always think of heatwaves as causing unbearable conditions for us, but did you know they happen in the ocean too? They're happening more and are becoming hotter, impacting everywhere from Tassie to Queensland. Read more in the latest brief from the Centre of Excellence for Climate Extremes.

The rate at which our planet warms matters. It is not just that rate of warming has direct impacts on heat stress and heat related mortality in vulnerable areas of the world, but it also affects Adaptation and Mitigation measure tackling climate change. climateextremes.org.au/is-the-clima...

Is the climate changing faster than expected? An excellent briefing note from the ARC Centre of Excellence for Climate Extremes looks at this question. climateextremes.org.au/is-the-clima...

'Global emergence of regional heatwave hotspots outpaces climate model simulations' our new paper in @pnas.org with S. Bartusek, R. Seager. J. Schellnhuber and M. Ting investigating the tail behaviour of extreme heatwave trends. @iiasa.ac.at @columbiaclimate.bsky.social @lamontearth.bsky.social

🆕A new climate oscillation may develop in the Arctic Ocean due to sea-ice melting. Air-sea feedbacks in the ice-free Arctic could trigger periodic warm-cold temperature cycles, resembling El Niño and La Niña in the tropical Pacific.🌏 www.nature.com/articles/s41...

In our recent GRL study- doi.org/10.1029/2024... - with @andrewkingclimate.bsky.social and Rob Ryan, we analysed global and regional accelerated warming. But, is an acceleration rate on the order of 0.001 degC/decade**2 really significant? The supplementary text contains the answer and it is - YES!!

New paper led by @adisen99.bsky.social shows how accelerating global warming has been associated with local warming acceleration experienced by some people but not everyone agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Another striking example of how we disturb the equilibrium of the systems components Arctic sea ice had a dampening effect on El Ninos and La NInas. Now as it vanishes less sea ice is thought to support the formation of stronger El Ninos and La NInas... #climate #uöäü1feedbacks #uöäü1ENSO
