A landmark article focusing on the culture of the coastal Maya has just been published by an international team of archaeologists, anthropologists, and marine scientists. Covering almost 3,000 years of history, their research has focused on an area which has previously been hidden from view by mangroves.

What will humanity choose...???

Huge parts of the world at the moment are either catastrophically flooded, experiencing unprecedented drought, smashed by strong storms or eroding into the sea.

I wonder what the takeaway from all this will end up being?

Will it be: ‘The climate scientists are right. Climate change is real and we all have to urgently change how we live?’

Or will it be: ‘We need to build higher dam walls, more levees, more houses on stilts, more coastal rock walls and pump desalinated sea water inland?’

I wonder..........

Book Review: “Charlie’s Good Tonight: The Life, the Times, and the Rolling Stones: The Authorized Biography of Charlie Watts” by Paul Sexton

Authorized biographies assure authors access to the people most able to shed light on the subject at hand.

And on the other hand, authorized biographies tend to shine little light on the subject at hand.

Such is the case with Paul Sexton’s “Charlie’s Good Tonight: The Life, the Times, and the Rolling Stones: The Authorized Biography of Charlie Watts.” The 368-page tome features forwards by and interviews with Mick Jagger and Keith Richards, alongside additional conversations with many of the principals in Watts’ life including his daughter, Seraphina, and granddaughter, Charlotte; producers and engineers including Glyn Johns; Bill Wyman, who retained his relationship with Watts after leaving the band; friends like Jools Holland; and Stones touring members including Chuck Leavell and Lisa Fischer.

For anyone who knows anything about the Rolling Stones, “Charlie’s Good Tonight” imparts little new information; the lack of reportage is best summed when Sexton writes of the drummer’s 2021 death from undisclosed causes that the family has “chosen to keep the precise details … a private matter.”

Worse than the lack of digging is Sexton’s desire to work himself into the story as much as possible, peppering his prose with such phrases as “he told me” and “when we first met.”

In the end, readers are left with the oft-documented story of an OCD-afflicted, immaculately dressed, straight-arrow Rolling Stone who uncharacteristically delved into hard drugs for a brief period in the 1980s and who may or may not have punched out Jagger after the singer called Watts’ hotel room looking for “my drummer.”

Highlights include explorations of Watts’ side activities leading jazz big bands; Watts’ characterization of Mick Taylor as “the most lyrical player we had” and his tenure being a “golden era;” and Wyman’s assessment of the Beatles-vs.-Stones debate:

“I still say the Beatles wrote better songs than us, and they sang better than us, but we were so much better than them live.”

File “Charlie’s Good Tonight” under relatively entertaining and not very informative.

two beach houses in my state have been swallowed by the ocean recently- within a few hours of each other- and there’s a lot more that are about to go the same way. we haven’t even had a named storm yet, so.... yeah. it’s awful for the wildlife and causes an overwhelming amount of pollution, and the most recent house falling into the ocean came with a transfixing video that I am definitely going to paint from.

in general though, this has been in my work for a long, long time.

By the end of March, the surface temperature of the world’s oceans was above anything seen in the 40 years that satellites have been measuring it.

Records were “headed off the charts” and, as the heat refused to fade for more than a month, the Earth marched into “uncharted territory”, scientists said.

The temperature at the ocean’s surface – like on land – is being pushed higher by global heating but can jump around from one year to the next as weather systems come and go.

But in the 2km below the surface, that variability is almost nowhere to be seen. The rising heat down there has been on a relentless climb for decades, thanks to burning fossil fuels.

“The heat-holding capacity of the ocean is mammoth,” says Dr Paul Durack, a research scientist specialising in ocean measurements and modelling at the US Department of Energy’s Lawrence Livermore National Laboratory.

“The ocean captures more than 90% of the imbalance of energy that we’re creating because of anthropogenic climate change.”

The ocean is much less reflective than the land and soaks up more of the direct energy from sunlight.

But as greenhouse gases trap more of the energy that’s reflected back – allowing less to escape to space – the ocean tries to balance itself with the heat in the atmosphere above.

A technical chart in a chapter of the latest UN climate assessment laid out the unfathomable heat gain. Between 1971 and 2018, the ocean had gained 396 zettajoules of heat.

How much heat is that? Scientists have calculated it is the equivalent energy of more than 25bn Hiroshima atomic bombs. And that heat gain is accelerating.

A study in January found the ocean gained 10 ZJ more in 2022 than the year before – enough heat to boil 700m kettles every second.

Compared with the ocean, according to a study in January the atmosphere has held on to about 2% of the extra heat caused by global heating since 2006.

To understand what’s happening below the ocean surface, out of sight of satellites, scientists look at a vast network of thousands of thermometerson buoys, ships, underwater gliders and permanent moorings.

Durack says it wasn’t until the early 2000s that a view of the changes in the ocean – long-predicted by climate scientists – started to become clear as more and more data became available.

But scientists have been able to get a longer view going back many more decades by using climate models.

“When we look at the climate models and compare them with the observations, we get consistent results across that simulated Earth and the real Earth. They’re all showing consistent warming.”

Dr Bernadette Sloyan researches changes in the ocean at Australia’s CSIRO government science agency and spends her days analysing ocean data.

“This is where the ocean is like a flywheel that drives our climate and that’s all because of the amount of energy it takes to heat it up,” she says.

“We have this constant talking between the ocean and the atmosphere that’s driving our weather and, annually, that’s our climate.”

Sloyan says the ocean has acted like the planet’s air conditioner, relentlessly absorbing extra heat.

“But that air conditioner isn’t just passive. It is not a free service. Adding that heat has come with ocean acidification, rising sea levels and changes in the frequency of extreme weather.”

The effectsof the extra heat are almost everywhere. As the ocean heats up, it expands, pushing up sea levels around the globe. Just over one-third of the rise in global sea levels is down to thermal expansion.

More heat means more marine heatwaves that have devastated marine ecosystems, causing bleaching on coral reefs and killing underwater plants that act like forests, providing habitats for marine life and acting as nurseries for fisheries.

Ocean heating could also radically alter marine food webs, with warmer conditions favouring smaller species and algae at the expense of the larger species that humans tend to eat.

In the deep ocean, where species have adapted to stable temperatures, scientists have said warming there in the coming decades could devastate marine life.

Around the tropics, where oceans are warmest, scientists have found species are already migrating towards the poles to find cooler waters. But with no other species able to take their place, this leaves behind waters stripped of marine life.

In places like the Mediterranean, where land blocks a route to cooler waters, Prof David Schoeman says many species will run out of ocean.

“Fish can’t just climb out of the water so they may have to go deeper,” says Schoeman of the University of the Sunshine Coast in Australia, who helped coordinate the latest UN climate assessment’s work on the ocean.

But if species go deeper to survive the heat, this could present another problem. Schoeman says near the surface waters easily mix with the air above to provide enough oxygen for marine life. But as deeper waters warm they hold less oxygen, potentially cutting off another survival option for some species.

Schoeman says much of the heat that has pushed surface temperatures to new highs in recent weeks is likely coming from below.

“Every year about 134 million atomic bombs of heat is being trapped by the ocean. It has kept global temperatures down and kept the land livable but we have to realise that energy hasn’t gone.”

The latest UN climate report says the warming of the ocean is likely to continue “until at least 2300” even if greenhouse gas emissions are low because of the “slow circulation of the deep ocean”.

Prof Matthew England, an oceanographer and climate scientist at the University of New South Wales, is on a video call and shows an image of the globe taken over the Pacific, where almost no land is visible.

“Remember the world is 70% covered by ocean. It should have been called Ocean, not Earth,” he says.

England says that simple physics means the ocean “has this huge ability to absorb heat and then hold on to it”.

England holds his arms out wide to show the size of one cubic metre of air. To heat that air by 1C, he says it takes about 2,000 joules. But to warm a cubic metre of ocean needs about 4,200,000 joules.

“By absorbing all this heat, the ocean lulls people into a false sense of security that climate change is progressing slowly.

“But there is a huge payback. It’s overwhelming when you start to go through all the negative impacts of a warming ocean.

“There’s sea level rise, coastal inundation, increased floods and drought cycles, bleached corals, intensification of cyclones, ecological impacts, melting of ice at higher latitudes in the coastal margins – that gives us a double whammy on sea level rise.

“The oceans have stored the problem,” says England. “But it’s coming back to bite us.”

"As a scientist who studies the evolution and development of coastlines and the impacts of sea level rise, I believe that large-scale seawall proposals raise important long-term questions that residents, urban leaders and elected officials at all levels of government need to consider carefully before they invest billions of dollars. In my view, this approach is almost certainly a short-term strategy that will protect only a few cities, and will protect only selected portions of those cities effectively."
