I would be the first to admit that the total GHG emissions that India generates is very high. And even though a transition is occurring, it is very slow and not remotely fast enough to limit warming to Paris targets.
Source: IEA, IIASA, Ember analysis • This is a ternary chart showing the relative contribution of three aggregated energy carriers – fossil, bio & other, and electrons – that sum to total final energy. 'Bio & other' refers to biomass and other energy such as heat.
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"

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.

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!!!

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 actual temperature change in different regions compared to a counterfactual world if the 1960–1990 warming trend had continued. It is clear that regions with a low HDI have warmed pretty much at the same rate post 1990. An increase in pollution levels in these regions while a decrease in pollution in high HDI regions, owing to the imposition of clean air acts, can explain some of these regional differences
📑 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.

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!

Many IPCC scenarios project an aggressive reduction in aerosols, but they lack nuances of regional diversity and diversity in aerosols types. But there are some other model intercomparison projects that take these into account like RAMIP and AerChemMIO
Have you wondered what causes Australia's droughts? Why sometimes the expected rainfall just doesn't come?

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.”

As extreme weather and the cost of energy dominates the headlines, knowing how to separate fact from fiction is more important than ever.

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...

Figures describing the nature of the asymmetry of ENSO-rainfall teleconnections in two regions - East Australia and South-East Asia. East Australia experiences a stronger wet response during La Niña compared to the dry response during an El Niño, leading to a wet-type asymmetry. South-East Asia however, the effect is opposite with a stronger dry response during El Niño leading to a dry-type asymmetry

Regional and performance of models in capturing the nonlinear asymmetric nature of ENSO-rainfall teleconnections for a July-June average.
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.

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.
Posting too many "clouds" on "Blue Sky" would mean we are "making it rain".. or perhaps "brainstorming". We can call long threads - Storms
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.
