It is not just Qatar and the like.  The U.S. southwest has witnessed tremendous population growth, due largely to air conditioning and water piping.  The Phoenix area had barely 100,000 inhabitants in 1950.  It now has over 4 million!

I'm reminded of a Mad Magazine piece where a good Samaritan reports to the phone company a pay phone that is vandalized on the NE corner of 7th Ave.  The receptionist asks where the caller is calling from, and is told, "The phone booth on the SW corner of 7th Ave."  A few minutes later, still in the vicinity, the good Samaritan sees a phone company truck and thinks, "Good on them for being prompt!"  The service truck pulls up to the phone booth at the SW corner of 7th Ave. and the driver jumps out with a sledge hammer and whacks the once-working phone to bits.  (from 1955, maybe? - friends of ours in the mid-60's had all the back issues.)

Does this explain "everything"?

Senegal Baobab Forest Swallowed by Mining
https://phys.org/news/2019-10-stunning-senegal-baobab-forest-swallowed.html

... In Bandia, 65 kilometres (40 miles) west of Dakar, one of Senegal's most beautiful baobab forests is gradually being devoured by cement manufacturers' limestone quarries. Locals complain that mining activity is crumbling their houses and damaging their health.

... White dust from the Senegalese cement-maker Ciments du Sahel's 20 quarries in the area coat the village as well as the baobab trees. Its huge plant is visible from miles around.

The government, keen to support local industry, approved an expansion of 236 hectares (580 acres) for Ciments du Sahel in June.

... Bandia forest has had protected status since 1933 and is home to a wildlife reserve with rhinos, zebras and giraffes that is a hit with tourists.

Only one fifth of the original forest is left—or some 2,000 hectares (4,900 acres)—according to Ngom. The number of quarries rose from two in 2002 to 20 in 2019, he said.

"There were mango trees here, eucalyptus, acacias, and baobab. When I was a boy, we played among the trees," he said. "They've all fallen down, one after another", Ngom said in Bandia, pointing out an abandoned mine in the distance.

"Look, not one flower is left, not one animal. Here, nature can no longer retake its rightful place," he said above the noise of passing lorry traffic.

Mekong Levels at Lowest on Record as Drought and Dams Strangle River
https://phys.org/news/2019-10-mekong-shrivels-drought-strangle-seasia.html

Along parts of Thailand's northeastern border at Loei, the kilometre-wide (3,300-foot) river has shrivelled to a few dozen metres, with boulders and bedrock encasing muddy pools of water.

From above, the encroaching banks of Laos and Thailand are now a thread of water apart, restricting fishing grounds to a slim channel.

Fishermen blame a combination of this year's weak monsoon and the Xayaburi dam, around 300 kilometres (185 miles) to the north.

Use of Neonicotinoids on Rice Paddies Linked to Fishery Collapse in Japan
https://phys.org/news/2019-11-neonicotinoids-rice-paddies-linked-fishery.html

A team of researchers with members affiliated with several institutions in Japan has found what they describe as compelling evidence of two fisheries collapsing due to use of neonicotinoid pesticides by nearby rice farmers.



... Back in 1993, fishermen working at two fisheries on Lake Shinji, Japan found that yields had suddenly dropped dramatically. The reason for it was not known but many suspected it was tied to the use of neonicotinoid pesticides by nearby farmers—a new practice. To find out if that was indeed the case, the researchers gathered data obtained by other teams studying the lake over a period ten years before and after the collapse of the fisheries.



In looking at the results, the researchers found that the year following the first use of neonicotinoid pesticides in the local area, the amount of zooplankton in the lake nosedived. This was followed by a very swift drop in population of the fish that fed on them. More specifically, they found that zooplankton biomass shrank by approximately 83 percent. That year the smelt harvest was just 22 tons, a dramatic drop from an average haul of 240 tons each year.



The researchers note that they also studied other factors that might have led to fishery collapse, such as nutrient depletion or changes in oxygen or salt concentrations. They report that they were not able to find any evidence showing that there might have been something other than pesticides killing the food fish ate leaving them to starve. They conclude that the evidence strongly suggests it was the introduction of neonicotinoid pesticides into the lake environment that led to the die-offs.

India air pollution at 'unbearable levels', Delhi minister says
https://www.bbc.com/news/world-asia-india-50280390

Air pollution in the north of India has "reached unbearable levels," the capital Delhi's Chief Minister Arvind Kejriwal says.

https://twitter.com/Varun_Jhaveri/status/1190887202319790080

... I think we are heading towards Delhi recording the most polluted day in the history of world!! Most of the Delhi areas are showing an AQI of 999 because the meters can't record above that. This is a DISASTER!

https://aqicn.org/city/india/new-delhi/us-embassy/

.... Five million masks were handed out in schools on Friday as officials declared a public health emergency and Mr Kejriwal likened the city to a "gas chamber".



Satellite imaging showed more than 3,000 incidents of stubble burning in neighbouring states last week. The practice is estimated to cause 44% of Delhi’s pollution.

... By Sunday the air quality had deteriorated further, with the air quality index measuring over 900 in some areas, far exceeding the level of 25 deemed safe by the WHO, and well above even the 500 mark deemed “severe plus”.

Visibility became so bad that more than 30 flights were redirected from Delhi airport.

... Sachin Mathur, 31, an auto-rickshaw driver in north-west Delhi, said he had to stay outside for work and he had been struggling to breathe and could barely keep his eyes open on the roads.

... “Over the past 10 years the situation has been getting worse. We never used to see pollution like this,” said Rao. “The past few days have been absolutely awful. We have seen many of our pupils falling sick and complaining of having difficulty breathing.

Experts Recommend Oxygen Tanks to Deal With Delhi's Crippling Pollution

... Shitty air quality is nothing new for residents in this part of India. Last year, air pollution was so bad in New Delhi that the government enlisted firefighters to shoot the skies with water. The idea was that that would help break up the pollution particles. In the past, experts have even advised residents in Delhi to begin wearing oxygen tanks to breathe more safely.

This time, however, the air quality has reached a whole new level of disgusting.

... In November, Chief Minister of Delhi Arvind Kejriwal called Delhi a “gas chamber” due to the extreme pollution, and the region saw a number of traffic accidents (with one turning out fatal) just a day later. Experts now speculate people who live in the Delhi region could legit need oxygen cylinders to safely breathe the air. In fact, residents could need five cylinders a day, according to India.com.

... Oxygen cylinders aren’t a part of any plan, but governments might consider allocating funding for those soon if things don’t get any better.

Does Climate Change Affect Real Estate Prices? Only If You Believe In It
https://phys.org/news/2019-11-climate-affect-real-estate-prices.html

For the large-scale study, researchers combined sea level data from the National Oceanic and Atmospheric Administration (NOAA), geographic data about climate change attitudes from the Yale Program on Climate Change, and proprietary data on millions of repeat real estate transactions from Zillow to examine patterns in high-risk areas.

They found that, even after taking myriad variables into account, homes projected to be under water located in climate change "denier" neighbourhoods sell for roughly 7 percent more than homes in "believer" neighbourhoods.

"If everyone were to say, 'I'm not buying beachfront property here because it's going to get flooded,' then prices would collapse. But if you don't believe in climate change, you might say, 'You guys are crazy. Climate change isn't a real thing, so I see a buying opportunity,'" explains UBC Sauder School of Business assistant professor and study co-author Markus Baldauf.

Because so many people live close to coastlines, adds Baldauf, the effects are amplified. "If you wanted to create a society that's really susceptible to climate change," he says, "you would arrange it like they have in the U.S., because the population centres are really close to the water."

The researchers also examined political party affiliations, and while right-leaning communities were heavier on climate deniers, the effect still occurred even when accounting for political differences.

More on New Delhi

We Are Running Out of Air
One suffocating city is a harbinger of health crises around the world.

Officials have implored the people of New Delhi to stay inside, indefinitely. Five million children in India’s capital have been handed face masks. Everyone is to keep windows closed. Contrary to the most fundamental medical advice, the city’s chief minister urged residents this week to “avoid outdoor physical activities.”

News images seem cut from an apocalyptic outbreak film. One of India’s holiest rivers is covered in toxic foam that looks like white cotton candy. Midday visibility is like a foggy dusk. The air reportedly causes people’s eyes to burn.

At the root is not some panic-inducing virus, though. The cause is simply pollution from agriculture and transportation. And the city’s air crisis is unique only in degree. The same elements are accumulating in the air everywhere. ...

Poorly planned Amazon dam project 'poses serious threat to life'
Operator faces choice of weakening 14km barrier or potentially devastating a biodiversity hotspot

by Jonathan Watts in Belo Monte

The biggest hydroelectric project in the Amazon rainforest has a design flaw that poses a “very serious” threat to human life and globally important ecosystems, according to documents and expert testimony received by the Guardian.

The studies suggest engineers failed to anticipate the impact of water shortages on the Pimental dam at Belo Monte, which has been closed and turned into a barrier. This is forcing the operators to choose between a structural weakening of the 14km-wide compacted-earth barrier and a reallocation of water in the reservoir or on the Xingu river, which is home to indigenous communities, fishing villages and some of the world’s most endangered species.

His concerns were echoed by Francisco del Moral Hernandez, an energy science specialist who coordinated an expert panel on Belo Monte in 2009. “We’ve always known this project is inefficient from the standpoint of power generation. What we did not imagine is the weakness of the civil engineering,” he said. “If I were living downstream of the dam, I would move upriver … It is absurd this was not foreseen.”

Brazil’s president, Jair Bolsonaro, who is reportedly planning to attend the completion ceremony for Belo Monte, has weakened protections for the environment and indigenous communities. Local politicians will urge him to push ahead with another mega-project in the volta grande, a giant new goldmine called Belo Sun, which would be powered by the dam.

and more....and more...and more....on how to wreck the rainforest, biodiversity and the livelihood of the local population.

[kassy]

You forgot this one:
They (federal prosecuters) also intend to appeal to the Brazilian government for emergency humanitarian aid to support riverine populations that have experienced a devastating decline of fish on which they depend for nutrition and income.

But i was really wondering what would fail in the design:
it says that water levels fell the previous day to a critical 95.2 metres, which posed a risk that waves “will reach areas of the dam not protected by rock” reinforcements. It asks permission for more water from the intermediate reservoir, a move which would put more pressure on an already strained hydrology.

Cute.

Hernandez and Sawakuchi said planners had been over-optimistic because historical data showed the Xingu river was lower on at least four occasions during the 50 years before construction started.

So that problem was 100% garanteed to show up during its lifetime.

Red tide is back off the coast of Florida. Residents aren't sure how much more they can take

It's the length of these red tides and their close succession that is so troubling, said the 32-year Naples resident.

"If you've been here 20 or 30 years, red tide was an event that was around for a weekend or a week," he said. "Now, we're looking at months."

Florida's red tide is caused by a species of algae called Karenia brevis, which release neurotoxins that can be deadly to wildlife and can even cause breathing problems in humans on land.

While red tide has occurred for centuries, the 2017-2018 event was the fifth-longest on record, and only the second since 2007 to hit Florida's east, southwest and northwest coasts at the same time.

Venice Underwater as Exceptional Tide Sweeps Through Canal City
https://phys.org/news/2019-11-venice-underwater-exceptional-tide-canal.html

Venice was hit by the highest tide in more than 50 years late Tuesday, with tourists wading through flooded streets to seek shelter as a fierce wind whipped up waves in St. Mark's Square.

The exceptionally intense "acqua alta," or high waters, peaked at 1.87 metres (six feet) as the flood alarm sounded across the Italian city of canals, the tide monitoring centre said.

Only once since records began in 1923 has the water crept even higher, reaching 1.94 metres in 1966.

The exceptional flood, which he blamed on climate change, was "a wound that will leave a permanent mark".



... Water taxis attempting to drop people off at the glamorous and historic hotels along the Grand Canal discovered the gangways had been washed away, and had to help passengers clamber through windows.

At the sumptuous Gritti Palace, which has played host to royals and celebrities over the decades, including Ernest Hemingway, Elizabeth Taylor and Richard Burton, the decadent bar was largely underwater.

Rich tapestries were piled onto tables, while the waters lapped around velvet sofas and leather-bound books.



... Pierpaolo Campostrini, a member of St. Mark's council, said the scale of the flooding on Tuesday had only been seen five times in the long history of the basilica, where construction began in 828 and which was rebuilt after a fire in 1063.

Most worryingly, Campostrini said, three of those five episodes occurred in the last 20 years, most recently in 2018.

[pikaia]

"...peaked at 1.87 metres ..."

This is meaningless to me. Measured from where? It would be more meaningful to give the depth of water in St. Mark's Square, for example.

[El Cid]

Seriously, Venice is worse than Miami and that is quite something. It is built on small islands in an originally marshy environment. It was floodprone even in the best of times but that was the tradeoff at the time: protected from raiders but flooded by the sea at times. Now, as water levels rise, it does not take much to destroy the whole place. There will be no Venice in 2100 and maybe not much of it even by 2050. We should not be surprised that cities built at/even below the sea level are going to disappear.

  Massive Mildura dust storm leaves Victorian town 'unliveable' amid 40C heat

Residents say such storms now occur on a weekly basis, as topsoil from drought-ravaged farms is blown through the town

https://www.theguardian.com/environment/2019/nov/21/victorian-town-mildura-unliveable-massive-dust-storm-40c-heat
  by Naaman Zhou

Excerpts:
Residents told Guardian Australia it was like a “wall of dust”, a danger to asthmatics, and “unliveable”. And, for many, it is not even the worst dust storm this year. In May residents reported a storm as the town’s worst in 40 years.

“This is bad but recently there have been probably been three or four a week.”

“I have been here for 10 years and have never experienced anything like this. We used to have a dust storm a year, this is now a weekly basis. At its worst I couldn’t see across the road. This time the heat, because it is 40C, coupled with the dust just made it unliveable. You couldn’t go outside.

“It is really concerning to have young children and to feel like you can’t leave your house. You’re kind of trapped.”

Appleby said the extended drought had devastated farming communities and made the dust storms more frequent.

“We haven’t seen rain in months. It is absolutely climate-induced. The drought in this region is crippling farmers. And the dust in the sky is that farmers’ topsoil. When you put it into perspective like that it is terrifying.”

Appleby, who also has a six-year-old in school, said it was scary to think that this would be the future for her children.

Melting Mongolian Ice Patches Threaten Ancient Practice Of Reindeer Herding

Nestled in the high-altitude Sayan Mountains in northern Mongolia perennial ice patches have long been central to the health of domestic reindeer and the lives of those that tend to them. Even during the hottest summer months, these “munkh mus” patches persisted, providing crucial water and cool reprieve for overheated reindeer.

But soaring temperatures in the region are melting this eternal ice at rates never seen in modern history. 

...

in the last two decades Mongolian temperatures have increased more than 1.4°C (2.5°F) above the 20th-century average – and the Tsaatan are seeing those impacts in real-time.

...

The Tsaatan are literally at the front lines of climate change. These are folks that contributed nothing to the problem that we find ourselves in globally, but they're the ones paying the first price."

Between 2016 and 2018, interviewees said that for the first time in their memory, ice patches are disappearing in the height of summer. Reindeer can easily overheat and rely on munkh mus for a reprieve from the summer heat, as well as for fresh drinking water supplies and to escape disease-carrying insects. Access to these ice patches is “critical” for the health and welfare of these animals.

"Losing the ice compromises reindeer health and hygiene and leaves them more exposed to disease, and impacts the well-being of the people who depend on the reindeer,” said veterinary researcher and study co-author Jocelyn Whitworth.

https://www.iflscience.com/environment/melting-mongolian-ice-patches-threaten-ancient-practice-of-reindeer-herding/

Once the ice is gone the herds will be gone too and so they lose their way of life, they will lose their world.

California’s Housing Crunch is Pushing Developers Deeper into Dangerous Fire Zones
Centennial, a new city with homes for 57,000, was designed as an anti-wildfire fortress. Ecologists say the development is at risk of burning.

The Santa Ana winds were blowing as Greg Medeiros ducked behind his Chevy Tahoe on a remote hillside 25 miles from the edge of Los Angeles’s sprawl. He gestured to the valley below, describing his vision of Centennial, the city he’ll build in the heart of wildfire country.

The project is critical to solving L.A.’s housing shortage, with homes planned for 57,000. Though the site is an area the state has deemed at high risk of wildfires, defense is built into the design, said Medeiros, vice president of the developer, Tejon Ranch Co.  On one side, the 200-foot-wide California Aqueduct will serve as a moat. The area also will have at least three fire stations and even a herd of cattle for strategic grazing, leaving less grass to burn.

To Chad Hanson, a forest ecologist who cofounded the John Muir Project, an environmental group, Centennial is just the latest example of California’s “hubris” in the face of wildfires that are growing more destructive.

“If you were to create a top 5 list of the absolute dumbest places in the entire state of California to build a new large development, this would be on the list,” said Hanson, who has hiked the area since he was a Boy Scout. “It flies in the face of everything we know about fire science and about how to keep people safe.”

California is on a collision course with climate change. For decades, the state has built ever deeper into its hills, canyons and valleys to provide cheaper housing for residents priced out of the cities. That growth now comes with existential risk. Rising temperatures and more frequent droughts are creating ideal conditions for wildfires, and a growing population outside the urban fringe brings more opportunities for accidental ignitions. ...

With Waters Rising And Its Population Falling, What Is Venice's Future? :

Many Venetians believe excavation of deep canals in the 1960s to accommodate oil tankers irreparably harmed the lagoon's delicate ecosystem. There's also widespread skepticism about a long-term project to build large, movable floodgates to hold back rising sea levels.
...
In the battle against rising sea levels, Venice is on the front line. That's why, says Bassi, it's the ideal laboratory in which to study climate change. Next year, his university will offer a new degree in environmental humanities, in which scientists provide the data, "but we need to imagine what climate change is going to be like. And for that, you need the artist, you need the intellectual, you need the poets, you need philosophers, you need the historians."

Perhaps their historians could begin with studies of the Egyptian City of Thonis or Heracleion. Another port city on the Mediterranean once famed for her bridges and canals.


About 10 meters below the waves at present.

Climate change is forcing one person from their home every two seconds, Oxfam says

(CNN)Climate-fueled disasters have forced about 20 million people a year to leave their homes in the past decade -- equivalent to one every two seconds -- according to a new report from Oxfam.

This makes the climate the biggest driver of internal displacement for the period, with the world's poorer countries at the highest risk, despite their smaller contributions to global carbon pollution compared to richer nations.

People are seven times more likely to be internally displaced by floods, cyclones and wildfires than volcanic eruptions and earthquakes, and three times more likely than by conflict, according to the report released Monday,

Mekong River is turning blue. That’s not good.

Water levels in the Mekong River are now reaching a critical point. The river’s normally brown waters have turned aquamarine, like sea water, and sandbars are emerging, some of them several kilometres long.

Arthit Panasoon, president of a conservation group in the northeastern province of Nakhon Phanom, says the rare change in water colour, although it might look attractive, is a deceptively gloomy sign that the river is running dry.

He explains that the average depth in his vicinity is now around one metre, the lowest in more than fifty years. Because it’s so shallow, the river flows slowly, causing sedimentation, usually kicked up from the riverbed, to sink and remain unmoved, producing the aquamarine colour.

Study Finds BPA Levels in Humans Dramatically Underestimated
https://medicalxpress.com/news/2019-12-bpa-humans-underestimated.html

Researchers have developed a more accurate method of measuring bispehnol A (BPA) levels in humans and found that exposure to the endocrine-disrupting chemical is far higher than previously assumed.

The study, published in the journal the Lancet Diabetes & Endocrinology on Dec. 5, provides the first evidence that the measurements relied upon by regulatory agencies, including the U.S. Food and Drug Administration, are flawed, underestimating exposure levels by as much as 44 times.

... BPA can be found in a wide range of plastics, including food and drink containers, and animal studies have shown that it can interfere with the body's hormones. In particular, fetal exposure to BPA has been linked to problems with growth, metabolism, behavior, fertility and even greater cancer risk.

Despite this experimental evidence, the FDA has evaluated data from studies measuring BPA in human urine and determined that human exposure to the chemical is at very low, and therefore, safe levels. This paper challenges that assumption and raises questions about other chemicals, including BPA replacements, that are also assessed using indirect methods.
