Nice cloud with ice falling out somewhere near Chippenham.

Revealed: how aviation emissions could be halved without cutting journeys Exclusive: Getting rid of premium seats, ensuring flights are near full and using efficient aircraft could slash CO2, analysis suggests Climate-heating emissions from aviation could be slashed in half – without reducing passenger journeys – by getting rid of premium seats, ensuring flights are near full and using the most efficient aircraft, according to analysis. These efficiency measures could be far more effective in tackling the fast-growing carbon footprint of flying than pledges to use “sustainable” fuels or controversial carbon offsets, the researchers said. They believe their study, which analysed more than 27m commercial flights out of approximately 35m in 2023, is the first to assess the variation in operational efficiency of flights across the globe.

Snowing and settling in Reading just now!

Tiny amount of snow in Reading this morning.

2025 was the warmest year on record for Central England in a dataset that starts in 1659.

Looking for postdoc positions in the UK studying weather extremes?

Two jobs with deadline 4th Jan:

Historical windstorms, working with two insurance companies: jobs.reading.ac.uk/Job/JobDetai...

Storylines of extreme events, as part of a European collaboration: jobs.reading.ac.uk/Job/JobDetai...

In the coming days pressure will begin to rise to the N & E of the UK

This will gradually cause Atlantic low pressure systems to slow down, weaken & start to retrogress in the vicinity of the UK

This will allow the high to become more dominant, with a colder E wind developing

Exciting jobs & PhD studentship!

1) postdoc in historical windstorms: jobs.reading.ac.uk/Job/JobDetai...

2) postdoc in extreme event storylines: jobs.reading.ac.uk/Job/JobDetai...

3) PhD in redeveloping the Central England Temperature series (led by Tim Osborn): www.findaphd.com/phds/project...

#StormBram on its final approach to the UK this evening..

China doesn’t want to take lead on climate policies alone, senior adviser warns Exclusive: A top official in Beijing’s Cop delegation says China is committed to clean energy – but America’s absence is a problem China is committed to the energy transition needed to avert climate breakdown – but does not want to take the lead alone in the absence of the US, one of the country’s senior advisers has told the Guardian. Wang Yi said China would provide more money to vulnerable countries, but the EU’s climate commissioner has warned Beijing is not doing enough to cut emissions. Continue reading...

Got much heavier after I sent that!

A little bit of wet snow seen in Reading just now towards the back of the band of rain moving south.

Cold night in Reading although cloud rolled in before dawn but with enough gaps to give a great red sky around sunrise.

After an exceptionally mild week across many areas, we are going to get a taste of winter as cold Arctic air plunges down from the north

So it's probably time to get the big coat out 🥶

Colder Arctic air on the way for the week ahead..🌡📉

Storm Amy has been record breaking ⚠️

An air pressure of 947.9 hPa was recorded at Baltasound, Shetland, provisionally setting a new UK lowest pressure record for October.

Northern Ireland provisionally recorded its strongest October wind gust on record, with a gust of 92 mph at Magilligan.

#StormAmy ’s magnificent swirl as seen from @eumetsat.int’s Meteosat-12 satellite 🛰️

EarthCARE is a inexhaustible source of beautiful imagery of some of the most spectacular phenomena nature has to offer, so I've started a Gallery page on the EarthCARE Science web site, showing for example convective motions in the trainbands of Typhoon Ragasa... www.earthcarescience.net/gallery

Opening of the Stockton and Darlington Railway in 1825. John Dobbin (1815-1888) c.1875. Painting held by the National Railway Museum, York. Crowds gather as Locomotion No.1 hauls dozens of wagons packed with passengers along a distant embankment and across a river via an elegant bridge.

#OnThisDay 200 years ago witnessed the birth of modern railways through the opening procession of the Stockton & Darlington Railway from Shildon to Darlington. Watched by thousands, Locomotion No.1 hauled hundreds of passengers aboard wagons and coach 'Experiment'.

Missed the total phase of the lunar eclipse because the moon was too close to the horizon. Did get to see the shadow receding across it though.

Air pollution can drive devastating forms of dementia, research suggests Airborne particles cause toxic clumps of proteins in brain that are hallmarks of Lewy body dementia, study indicates Fine-particulate air pollution can drive devastating forms of dementia by triggering the formation of toxic clumps of protein that destroy nerve cells as they spread through the brain, research suggests. Exposure to the airborne particles causes proteins in the brain to misfold into the clumps, which are hallmarks of Lewy body dementia, the second most common form of dementia after Alzheimer’s disease.

Wind and rain incoming tonight/tomorrow

Last night in Reading at around 17:30 UTC saw one of the brightest and most complete rainbows I’ve seen for a while (the photo doesn’t do it justice).

Summer 2025 is the warmest on record for the UK Provisional Met Office statistics confirm that summer 2025 is officially the warmest summer on record for the UK.

New analysis from @metoffice.gov.uk showing that the record-breaking hot UK summer of 2025 has been made much more likely by human-induced climate change and such a hot summer would be expected about once every 5 years in current climate. www.metoffice.gov.uk/about-us/new...

Nice fall streaks seen from Reading earlier today. The front produced a small amount of rain (less than 0.1mm) but we did have one loud clap of thunder.

Low-income and minority ethnic people in England most at risk from dangerously hot homes Exclusive: Homes are heating up as summers get hotter but least well-off are shouldering greatest risk, study finds * Why UK housing is dangerously unprepared for impact of climate crisis * From shutters to reflective paint: how to prevent UK homes overheating Lower-income householders, minority ethnic people and those with young children are more likely to live in homes at risk from dangerous overheating, research has found. The UK has baked in multiple heatwaves this summer, with many people sweltering in dangerously hot homes that were not designed to withstand extreme temperatures. June was the hottest on record and in general this summer England was an average of 1.58C above average temperatures. Continue reading...

First heavy rain in Reading for a long time!

Rainbows in the sky just now.
