Whereas increased strat water vapour apparently increases surface temps, it cools the strat, particularly near the tropopause. This is currently apparent as 10hpa temps in NH have been at record low levels. Also, Nacreous clouds formed in cold lower strat have been seen earlier and at lower latitudes then normal. Below is one I captured last week, even my family were impressed and most often when I point out some atmospheric phenomena they aren't 🤷‍♂️ As is often the case a camera struggles to capture the sky as we see it, but if you can imagine an oystery glowing cloud?? Overall, it seems there is much evidence that the HT eruption has had noticeable effects on our atmosphere and the injection of increased moisture into upper atmosphere is now well mixed. (Tho more prevalent in southern hemisphere) For anyone discussing current surface temperatures to not mention the HT event leaves them either misleading or ignorant. Seeing as it's never mentioned, it seems there's alot of misleading and ignorant people out there.....

"Scientists desperate to stop or reverse climate change are dumping chemicals in the ocean and spraying saltwater in the air. What can go wrong?" mishtalk.com/economics/scientists-try-risky-air-and-water-experiments-hoping-to-reverse-climate-change/"Experiments Underway Marine Cloud Brightening: Researchers aboard a ship off the northeastern coast of Australia near the Whitsunday Islands are spraying a briny mixture through high-pressure nozzles into the air in an attempt to brighten low-altitude clouds that form over the ocean. Scientists hope bigger, brighter clouds will reflect sunlight away from the Earth, shade the ocean surface and cool the waters around the Great Barrier Reef, where warming ocean temperatures have contributed to massive coral die-offs. The research project, known as marine cloud brightening, is led by Southern Cross University as part of the $64.55 million, or 100 million Australian dollars, Reef Restoration and Adaptation Program. Stardust Solutions: In Israel, a startup called Stardust Solutions has begun testing a system to disperse a cloud of tiny reflective particles about 60,000 feet in altitude, reflecting sunlight away from Earth to cool the atmosphere in a concept known as solar radiation management, or SRM. Dumping Lye in the Ocean: In Massachusetts, researchers at the Woods Hole Oceanographic Institution plan to pour 6,000 gallons of a liquid solution of sodium hydroxide, a component of lye, into the ocean 10 miles south of Martha’s Vineyard this summer. They hope the chemical base will act like a big tablet of Tums, lowering the acidity of a patch of surface water and absorbing 20 metric tons of carbon dioxide from the atmosphere, storing it safely in the ocean."

Interesting that the UAH lower stratosphere temp. anomalies over the tropical oceans declined after Hunga Tonga ... while lower and middle troposphere temps increased. [img src=" " alt=" "]

Global medium-range weather forecasting is critical to decision-making across many social and economic domains. Traditional numerical weather prediction uses increased compute resources to improve forecast accuracy, but cannot directly use historical weather data to improve the underlying model. We introduce a machine learning-based method called "GraphCast", which can be trained directly from reanalysis data. It predicts hundreds of weather variables, over 10 days at 0.25 degree resolution globally, in under one minute. We show that GraphCast significantly outperforms the most accurate operational deterministic systems on 90% of 1380 verification targets, and its forecasts support better severe event prediction, including tropical cyclones, atmospheric rivers, and extreme temperatures. GraphCast is a key advance in accurate and efficient weather forecasting, and helps realize the promise of machine learning for modeling complex dynamical systems.

I wonder what the Obamas think about dangerous experimentation going on near their holiday home?

Carbon Greening of the planet does not impress the Catastrophists. Are we surprised?

Brandon should should purchase this guy and the program. Could make people think that the words exiting his mouth actually mean something coherent.

There is an article in Zero Hedge about plans for geo-engineering planetary climate.
Basically, the idea is to put stuff into the upper atmosphere to increase planetary albedo.
Sadly, if the planners have the science wrong - which I think is possible - they might end up accelerating a downward spike in planetary temperatures.
That would be a true crime against humanity.

It is 8th March, but as far as I can see Dr Roy Spencer's February temperature figures have yet to appear.
Have I missed something?

NOAA has announced that they will no longer be reporting MVENSO. Two of the key indicators of the global ocean current cycle, MVENSO and AMO, are now unavailable.

I'd hate to think it had anything to do with the recent divergence between MEI and ENSO3.4. Maybe another retirement? Chart below is a comparison of 3 years (1 before and 2 after) El Nino events across solar cycles. Something went haywire in 2022-23. Who knows what happened with the AMO. Inconvenient? Or other?
