This is so unusual. That's a *huge* amount of energy being transferred to the atmosphere. Expect extreme temperature and storm records. Just the top few metres of our oceans store as much energy as the entirety of our atmosphere. I'm very concerned for later this year into 2024.

A complete shutdown of cold water ocean upwelling off the coast of Peru is the sign of a strong impending El Niño... It was along this coast that the phrase was first coined by colonial Spanish fishermen. This is a huge anomaly.

Today, there are ox bow lakes in the sky. A river is driven by gravity. The polar jet stream is driven by the temperature difference between the Arctic and lower latitudes. That difference is getting smaller. And like a river, the jet stream meanders. [1/5] @cambecc

"Poison": How much cyanide in a glass of water will kill you? 20%? 10%... No, it's 0.0003% (3 ppm). This idea that 0.042% (420 ppm) of CO2 in our atmosphere (up 140 ppm in 150 years) must be harmless is simple stupidity & damn right ignorance of basic science.

For context, oceans between 60N and 60S have been around 0.15C above the previous record for two and a half months! I'm not sure if anyone else has calculated this, but using the Stefan-Boltzmann Law & lots of rounding, that's ~ an extra 975 TW of energy passed to the atmosphere.

#ArcticFires : I'm getting lots of queries about what exactly is burning in the #ArcticHeatWave (is it the boreal forest? is it tundra? are the fires on peatlands?) Here's some original analysis using fire hotspots, a land cover map, and a peatland map. Results in next tweet [1/4]

Don't get muddled up between air temperature & surface temperature @BBCNewsnight . Air temperatures will not reach 60°C in Athens. Surface temperatures might. These are highly dependent on land cover & variable even between buildings. It misleads on an important story.

UK friends & others in northerly latitudes: I highly recommend going somewhere dark tonight. This is the strongest solar storm in 20 years. There are clear skies for most of the UK. A once-in-a-lifetime opportunity to see #aurora for many. [1/6] Want to know more... Read on

@LBHF @DefraUKAir I will be complaining to the @LBHF Air Quality Team, my local councillors ( @lizcollins777 & @walshpatrick95 ), & my MP @andyslaughtermp (AGAIN). *Again*, because this is not the first time that I've complained about the pub (see this email from February, this year). [9/n]

@LBHF I had a very good idea where this smoke was coming from. After a short walk upwind from my flat, I headed to the pub on the opposite side of the road from my estate (& not for a pint!) They were burning wood on an open fire. This is illegal (more details below). [3/n]

@LBHF @DefraUKAir @Lizcollins777 @walshpatrick95 @andyslaughtermp @drkrischan @IQAir @RuthNewportWest @AdamDKHarrison Finally, wood-burning is not a 'green' alternative to fossil fuels. Burning wood rapidly releases CO2, when the wood carbon might otherwise slowly decompose or be stored. It's also less carbon-efficient than other energy sources: @dsawsp [17/17]

Are you paying attention yet? The North Atlantic SST anomaly on June 8 was 1.04°C above the 1982-2023 mean. For those keeping track, that's 3.56σ, or 1-in-5400.

WTF is up with ocean surface temperature anomalies? This worries me a lot. shades of red = warmer than average, shades of blue (which are almost non-existent!) = cooler than average.

Thank you to those with thoughtful replies about the importance of tackling a global crisis. Today my grandmother died. I was there, and this was a distraction. Sometimes there are moments when personal moments matter more. But if I'm to be a grandfather, we need to come together

Daily timelapse @NASAEarth image (110 km wide) showing the spread of this large wildfire in Quebec. In two weeks it has burnt over 2,500 km² (250,000 ha), about the size of Rhode Island, Dorset, or twice the area of Central London. 🔥🛰️🇨🇦 🧵[1/4]

@LBHF To start with, it's an offence to emit smoke from a chimney in 'smoke-control areas' (all of @LBHF ). Smoke isn't always visible, but this illegal fire was producing obviously thick smoke, billowing from the pub's chimney towards council flats & student housing opposite. [4/n]

@cathyslifeSP @nintendobenzo @_ppmv Complete nonsense in that tweet. Pre-industrial CO2 was 280, now it's 420 (we have contributed far more than 3%) As for CO2 being insignificant. O3 is 10-times less prevalent in our atmosphere than CO2 and saves all life on land from DNA destroying UV radiation. Let that sink in!

Sorry that image was from a week ago, when things were bad. They're worse now, especially in Sumatra. Here's today's image. Just goes to show how little attention this is getting. Things have been bad for weeks.

This is a #wildfire near the China-Russia 🇨🇳🇷🇺 border inside #AmurOblast (49.4N 129.7E) 7 May '20. The fire is ~15 x 10 km. This beautiful image demonstrates the power of 'false-colour' composites for visualising satellite data. What does it show? [🛰️Remote Sensing THREAD: 1/6]

@LBHF In front of the council flats & student accommodation, the sensor measured PM2.5 at 60 µg/m3 (unhealthy for everyone, increasing risk of aggravation to the heart & lungs). On the walkway in front of my flat it was 45 µg/m3 (unhealthy for sensitive groups, e.g. asthmatics). [5/n]

@LBHF @DefraUKAir @Lizcollins777 @walshpatrick95 @andyslaughtermp @drkrischan @IQAir @RuthNewportWest @AdamDKHarrison Domestic sources of PM2.5 in cities were all-but eradicated by the Clean Air Act 1956 & the transition to gas/electric heating in the 1960s/70s. This regressive trend for (arguably unnecessary) wood burning in urban areas is negating that progress. [16/n]

In a decade we have re-reversed where we find poor air quality in cities. [left] Hammersmith Broadway Bus Station, relatively clean air, windows open. [right] Estate with no through traffic, but downwind of people illegally burning wood. Photos taken within 10 mins of each other.

@LBHF The rules about what you can & cannot burn, & in what appliances, aren't well-communicated. However, once you find them, both @DefraUKAir & the council's websites state that wood must be burned in 'exempt appliances' (e.g. a Defra-approved log burner), not on open fires. [7/n]

@Hwells28 The past: - Medieval Britain life expectancy: 31.3 years. - People who died in London's great smog of 1952 (due to solid fuel burning): 10,000-12,000. The 'modern problem': - Single-biggest source of PM pollution in the UK today: domestic solid fuel burning (worse than traffic).

This small Greek island (Rhodes, 140,000 ha) will be top of the news today because of a tiny minority of relatively rich people evacuating from holidays. I can't help but compare it with the lives & homes lost elsewhere in the world & the 'inconvenience' of @JustStop_Oil protests

Tropical rainforests are one of the few biomes on our planet where we should *not* expect fires. 🔥 This image (3000 km across) reveals a pattern of human destruction; every road & waterway through the forest is illuminated by fire tendrils in stark contrast to the intact forest.
