Record heat turns deadly in Japan on Sunday, relief to arrive on Tuesday
Quote
All-time high temperature records were broken on Sunday in Japan as temperatures soared over 38 C (100 F).

Summerlike temperatures took over Japan on Sunday with temperatures rising to 39.5 C (103 F) on the island of Hokkaido, according to the Japanese Meteorological Agency.

This was the first time the temperature has ever risen past 38 C (100.4 F) in Hokkaido during any month of the year. This temperature also set a new record for the highest temperature during the month of May in all of Japan. ...

India Heatwave Temperatures Pass 50 Celsius   
https://phys.org/news/2019-06-india-heatwave-temperatures-celsius.html



Temperatures passed 50 degrees Celsius (122 Fahrenheit) in northern India as an unrelenting heatwave triggered warnings of water shortages and heatstroke. 

The thermometer hit 50.6 degrees Celsius (123 Fahrenheit) in the Rajasthan desert city of Churu on Saturday, the weather department said.

The Indian Meteorological Department said severe heat could stay for up to a week across Rajasthan, Maharashtra, Madhya Pradesh, Punjab, Haryana and Uttar Pradesh states.

Several deaths from heatstroke have already been recorded.

A red alert severe heat warning has been issued in the capital New Delhi as temperatures passed 46 Celsius, and residents were advised not to go out during the hottest hours of the day.

Several major cities, led by Chennai, have reported fears of water shortages as lakes and rivers start to dry up.

In the western state of Maharashtra, farmers struggled to find water for thirsty animals and crops.   


Quote
... "There is no drinking water available for days on end and we get one tanker every three days for the entire village," Tonde told AFP.

"We are scared for our lives and livelihood," he added.

Farther west, the temperature rose to a blistering high of 51 C (124 F) in Jacobabad, Pakistan on Saturday.

Chennai's Largest Source Of Drinking Water Dries Up, Residents Hit Hard   
https://www.google.com/amp/s/www.ndtv.com/chennai-news/chennais-largest-source-of-drinking-water-dries-up-residents-hit-hard-2045155%3famp=1&akamai-rum=off

Chennai: Chennai's largest source of drinking water, Chembarambakkam lake, is bone dry with parched and cracked bed all over. The 3,500 million cubic feet capacity reservoir is left just with storage of silt and slush in the middle largely due to deficit monsoon last year. It was this very lake that overflowed and flooded Chennai in December 2015.

Chennai Metro Water, which supplies drinking water, has cut piped supply by 40 per cent.

Quote
... "Before elections we were getting water regularly. Now we don't get regular supply. We get water just for one hour and half the time it's like toilet water. Tankers come only around 10 or 11 am. It's so difficult."

-----------------

Drought-Hit Chennai Has 1.3% of Water in Its Reservoirs, One of the Lowest in 70 yrs 
https://www.google.com/amp/s/www.thenewsminute.com/article/drought-hit-chennai-has-13-water-its-reservoirs-one-lowest-70-yrs-102038%3famp

... According to data from the Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB), as of Sunday, Chembarambakkam Lake has only 1mcft of water compared to its capacity of 3645 mcft, Redhills has 28 mcft compared to 3300 mcft of storage, Poondi contains 118 mcft of water as opposed to its storage of 3231 mcft and Cholavaram has 4 mcft compared to a total capacity of 1081 mcft.

... Chennai had received only 390 mm of rainfall in 2018 as against the normal of 850mm during the Northeast monsoon, when it gets a bulk of its annual rainfall.

 "At this rate these four reservoirs will be empty by July.


Chennai is already battling an acute water crisis despite CMWSSB rationing supplies from January. From the total daily supply of about 880 million litres a day, it has been brought down to 550 million litres a day. On May 15, CMWSSB stopped drawing water from the Redhills lake, which supplies the city 90 million litres-120 million litres a day.

Loss of Arctic Sea Ice Stokes Summer Heat Waves in Southern U.S.   
https://m.phys.org/news/2019-06-loss-arctic-sea-ice-stokes.html

A new study in AGU's Journal of Geophysical Research: Atmospheres explores how seasonal fluctuations of sea ice coverage trigger changes in atmospheric circulation patterns during the boreal summer.

The study draws upon four decades of satellite data of Arctic sea ice coverage collected between 1979 and 2016, overlapped with heat wave frequency data across the United States during the same time period.

The team found evidence for a strong statistical relationship between the extent of summer sea ice in the Hudson Bay and heat waves across the southern Plains and southeastern U.S 

Quote
... "The latest research on this topic suggests that declining Arctic sea ice may be linked to increased incidence of extreme weather patterns across the northern hemisphere," said Dagmar Budikova, a climatologist at Illinois State University in Normal and lead author of the new study. "Our results confirm this hypothesis by offering further evidence that Arctic sea ice variability has the potential to influence extreme summer temperatures and the frequency of heat waves across the southern U.S."

The new study finds the loss of sea ice across the Arctic begins with warmer-than-usual spring temperatures in the Hudson Bay and Labrador regions in the southeastern Canadian Arctic.

"This process starts when temperatures across the southeastern Canadian Arctic and northwestern Atlantic are 2 degrees [Celsius] warmer than expected in March, April and May," Budikova said.

This springtime warming lessens the north-to-south change in temperature between the high and middle latitudes of eastern North America, leading to a reduction in the strength of regional wind patterns. These conditions are symptomatic of weakened large-scale movements of air that appear to persist into the summer months, Budikova said.

If Climate Goals Aren’t Met, Extreme Heat Will Kill Thousands in U.S. Cities

A new report estimates as many as 2,700 heat-related deaths can be prevented in just one city if global temperature rise can be limited to 1.5 degrees Celsius.

...

extreme heat in the U.S. already causes more deaths than any other severe weather event, killing an estimated 1,500 people each year.

...

They estimate that as many as 1,980 deaths per city could be avoided in a 1-in-30-year heat wave event if global heating is limited to 2 degrees Celsius, rather than 3 degrees. If temperature rise is limited to 1.5 degrees Celsius, the potential number of lives saved jumps up to as much as 2,716.

...

The researchers also calculated that the number of “hot days”—when the mean temperature falls above what their model say is associated with the lowest mortality risk—would also significantly fall if global warming is limited to 1.5 degrees Celsius. San Francisco, on the higher range, could see 510 fewer hot days; St. Louis, on the lower end, could see a reduction of 202 days.

If the world hits that 3-degree threshold, once-rare heat cataclysms would become routine. An event as deadly as the three-day 1995 heat wave in Chicago, which killed 739 people—many of them elderly, isolated, and living on fixed incomes—could happen once every 1.4 years. That frequency could be halved to a 1-in-2.8 year event if heating is limited to 2 degrees Celsius, or once every 4.7 years under a 1.5 degree scenario—still plenty alarming in itself, Lo says, but that the “multiple times difference” in frequency across the three warming scenarios should not be ignored.

My wife worked nights in a level 1 trauma center on the near west side of Chicago during that 1995 heat wave, one of 3 such centers in the city.

People started being transported to her hospital in a trickle. They had no idea what was about to happen. Within 24 hours they were getting between 5 and 10 per hour with core temperatures in the low 100's. They would put the bodies on ice and start transfusions. These people would be throwing clots all over their bodies with organs shutting down. Most died.

She would come home from work completely exhausted.

Heatstroke Kills Monkeys as India Suffers in Searing Temperatures 
https://www.independent.co.uk/news/world/asia/india-heatwaves-monkey-deaths-water-madhya-pradesh-a8950131.html?amp



A troop of monkeys died from suspected heatstroke in India as scorching temperatures that have lasted more than a week take a mounting toll on humans and animals, media reports said Saturday.   

The monkeys died in Joshi Baba forest range in Madhya Pradesh state where the thermometer reached 46 Celsius (114 Fahrenheit).

District forest officer P. N. Mishra said the primates were believed to have fought with a rival troop over access to a water source.

"This is rare and strange as herbivores don't indulge in such conflicts," Mishra told NDTV network.

Tigers have also been reported to be moving out of forest reserves into villages in search of water, causing alerts.

Temperatures touched 50.3 degrees Celsius in the Rajasthan town of Churu last week, just shy of India's record of 51 degrees.

... Deadly dust storms swept across Uttar Pradesh Thursday night, resulting in at least 26 deaths and injuring more than 50 others.

More dangerous heat is expected in Jacobabad and surrounding locations into the new week as temperatures may climb back above 50 C (122 F).

India Heat Wave Triggers Clashes Over Water
https://dw.com/en/india-heat-wave-triggers-clashes-over-water/a-49110943

Police were tasked with guarding water tankers and water sources in Madhya Pradesh state in central India, the Times of India reported on Saturday, following clashes over water in the state and other parts of the country.

At least six people were stabbed by a man near Ranchi, the capital of Jharkhand state, on Friday. There was a fight with a man from a neighboring village who was filling barrels of water from a tanker, according to a report on NDTV. A man died in a similar fight on the same day in southern Tamil Nadu state. Two men were seriously injured in a fight over water in Madhya Pradesh on Wednesday and a tanker truck driver was beaten up in the same state a day earlier.

Residents of remote islands in the oceans have a great advantage (except for the threat of flooding). In the oceans, warming is much less, so the remote islands will overheat much later. Probably the real estate in Hawaii in the future will be even more expensive than now.

True, in the future, an increase in the number of strong earthquakes with tsunamis is expected, which may nullify all the advantages of remote islands. In general, the best space colonies :)

The tweet above went viral, prompting a more detailed explanation. “Omega Block”
Quote
Mika Rantanen (@mikarantane)6/10/19, 2:43 AM
Last week the jet stream in Europe was unusually wavy. This was the situation two days before the record-hot day in Finland - you can clearly see how our country was situated on the warm side of the jet. 
https://twitter.com/mikarantane/status/1137973523929018368
- This was the primary reason for the exceptionally high temperatures. The synoptic pattern, namely the omega block causing the heatwave, was actually seen in the forecasts over a week beforehand.
- By the way, there are some evidence that the jet stream may become more wavy in response to climate change. Here's just a small sample of papers showing this:
iopscience.iop.org/article/10.108…
nature.com/articles/s4146…
link.springer.com/article/10.100…
- In Finland, the heatwaves are projected to become more frequent, intense and longer. Due to "background warming", extreme temperatures will occur with less pronounced circulation anomalies.
See a good paper by Sol Kim, @VSinclair_Met, @RRuuhela et al:
rmets.onlinelibrary.wiley.com/doi/full/10.10…
- So, although this was just one case, and primarily caused by the wavy jet, #climatechange increases the risk of record-high temperatures.
It's like how alcohol increases the risk of crashing your car, or how doping increases the probability of setting new records in sports.

Four Passengers Die in 'Unbearable' Heat on Indian Train
https://phys.org/news/2019-06-passengers-die-unbearable-indian.html

Four people died in 'unbearable' heat while travelling by train in northern India, which has been in the grip of a heatwave for two weeks, officials and passengers said Tuesday. 

The four died Monday while travelling from Agra—the city of the Taj Mahal—to Coimbatore in the country's south.

"Heat seems to be a factor," Indian Railways spokesman Ajit Kumar Singh told AFP, "it is really unfortunate".

"When the train was approaching Jhansi, we got a call from the on-board staff that one of the passengers is unconscious," Singh said.

"We rushed medical staff to the station but they found that three of the passengers were already dead."

A fourth person died later in hospital.

Temperatures have hovered around 45 degrees Celsius (113 Fahrenheit) in Jhansi, in northern Uttar Pradesh state, in recent days.

Singh said the Kerala Express train had no technical problems, but the tourists were not in air-conditioned coaches.

A passenger who was a part of the group that boarded in Agra said the train was stiflingly hot.

"Shortly after we left Agra, the heat became unbearable and some people started complaining of breathing problems and uneasiness," the passenger was quoted as saying by News18 television.

"Before we could get some help, they collapsed."

Folks in the western U.S. are sweltering under an unusually intense June heat wave, with temperatures soaring to near-record highs from Oregon to Arizona.

Heat warnings and/or advisories were in effect Tuesday for a number of major metro areas in the West, including Las Vegas, Phoenix, Portland, Sacramento and San Francisco.

On Monday, normally mild San Francisco soared to a brutal high of 100 degrees, the first time that city has ever hit the century mark in June. (... 102° at 4:57 PM PDT.) The heat warped tracks on the city's transit lines, the Weather Channel said, and led to tens of thousands of power outages. A number of records were demolished in the Bay Area as well, such as 107 degrees in King City and 105 degrees in Salinas.

Monday was also only the seventh time on record the city reached 100 degrees, AccuWeather said.  More record heat was forecast for Tuesday, where the average high is in the upper 60s.

Monday's low temp of 72° in San Francisco broke the city's monthly maximum low temp record, previously 70° [set on 6/24/1976 & 6/6/1883]. It was also the 3rd all-time warmest night on record, behind the all-time maximum low of 75° [set on 9/2/2017 & 9/8/1904]

An excessive-heat warning was even in effect in typically hellish Death Valley, California, where a high of 120 degrees was forecast for Wednesday.

... One expert, UCLA climate scientist Daniel Swain tweeted Monday that "our recent work suggests that we're reached the point where a majority (perhaps even a vast majority) of unprecedented extreme heat events globally have a detectable human fingerprint."

India Staring at Longest Heatwave in 3 Decades
https://m.hindustantimes.com/india-news/india-staring-at-longest-heatwave-in-3-decades/story-zM1sSWQ3p63smxTErFVClJ_amp.html

The Capital, Delhi, which sweltered on its hottest June day in history on Monday (48 degrees Celsius) recorded a maximum temperature of 45.4 degrees Celcius at Palam in spite of a spell of light rain in the morning.  Dholpur in nearby Rajasthan was worse at 51°C. It was the fourth time that the temperature crossed 50°C in June in the state, according to Indian Meteorological Department.

With a heatwave spell stretching 32 days, 2019 has already seen the second-longest spell of scorching temperature ever recorded. If the mercury doesn’t dramatically drop in the next two days, 2019 will become the year with the longest heatwave spell in recorded history — with three weeks to go in June.

... The blazing heatwave is in line with predictions made by a number of scientific studies based on IMD data that show that the intensity of heatwaves is rising. DS Pai, a scientist at IMD, Pune, said their study of long-term heatwave data of 35 metrological sub-divisions showed a threefold increase in heatwaves every year since 1991. “Our observation indicates that the increase was steeper in the last two decades,” he said. ... “With climate change, the frequency and intensity of heat waves in India will increase,” [/iS Krishnan, a senior scientist at IITM, said.

... In major cities across northern India, the demand for power and water surged even as many sources of water – such as rivers and reservoirs – ran dry. The peak power demand in Delhi broke all records of this season on Monday and touched a high of 6,686 MW, reported the discoms. In the hinterlands, where there are often no secondary sources of water such as tanks and pipes, the situation is worse.

In Sonbhadra district on the eastern tip of Uttar Pradesh, for example, the scorching sun has forced many villagers to dig pits in the riverbed and wait for groundwater to ooze out. As the temperatures rise, the pits will go dry and villagers will have to trek kilometres for a pot of water. Hand pumps often don’t work in these regions because in many pockets, the water level has dipped below 300 feet.

The sweltering heat has driven tens of thousands of people into hill stations (mountain park hotels) that are ill-equipped to handle a rush of such magnitude. Uttarakhand’s Nainital has seen an average of 15,000 to 20,000 tourists arrive daily in a city with a capacity of just 8,000 rooms. Mussoorie, which has 2,000 rooms, has seen 190,030 tourists flood the town since May.

As many as 15,000 vehicles have entered Manali and Shimla on weekends this month, translating to roughly 60,000 people — about a third of the population of these towns. The tourist influx is repeatedly choking all approach roads to the small Himalayan hill stations (mountain park hotels) and causing massive traffic snarls in the mountains. Moreover, the hills have received no respite from the blistering sun — Monday’s maximum temperature for Mussoorie was six degrees above normal at 30.5 degrees Celsius while Dharamsala recording a maximum of 33.8 degrees Celsius.

Indian Villages Lie Empty as Drought Forces Thousands to Flee
https://amp.theguardian.com/world/2019/jun/12/indian-villages-lie-empty-as-drought-forces-thousands-to-flee

Hundreds of Indian villages have been evacuated as a historic drought forces families to abandon their homes in search of water.

The country has seen extremely high temperatures in recent weeks. On Monday the capital, Delhi, saw its highest ever June temperature of 48C. In Rajasthan, the city of Churu recently experienced highs of 50.8C, making it the hottest place on the planet.

Further south, less than 250 miles from the country’s commercial capital, Mumbai, village after village lies deserted. Estimates suggest up to 90% of the area’s population has fled, leaving the sick and elderly to fend for themselves in the face of a water crisis that shows no sign of abating.

... Wells and handpumps have run dry in the 45C heatwave. The drought, which officials say is worse than the 1972 famine that affected 25 million people across the state, began early in December. By the end of May, Hatkarwadi had been deserted with only 10-15 families remaining out of a population of more than 2,000.

With 80% of districts in neighbouring Karnataka and 72% in Maharashtra hit by drought and crop failure, the 8 million farmers in these two states are struggling to survive.

Parts of India: Heat wave causes vegetable prices to rise 40% in one week
https://www.freshplaza.com/article/9113284/parts-of-india-heat-wave-causes-vegetable-prices-to-rise-40-in-one-week/

The heatwave sweeping through large parts of India has made vegetable prices skyrocket with some areas seeing a 25-40% rise in bills in the past 10 days. Traders said prices are likely to remain volatile until monsoon rain covers the main growing areas in the country. In April, wholesale prices of food rose 3.4%, but fruits and vegetable prices were up 14%.

Kailash Tajne, president of the Vashi Agricultural Produce Market Committee (APMC), said that vegetables were selling for 30-40% more than usual price since the past 10 days.

Lithuania Temperatures Hit Record Highs Amid Baltic Heatwave
https://www.france24.com/en/20190613-lithuania-temperatures-hit-record-highs-amid-baltic-heatwave

Lithuanian temperatures have hit record June highs, meteorologists said Thursday, as a heatwave forced school closures and threatened to reduce harvests in the drought-hit Baltic region.

Kaisiadorys in central Lithuania was the hottest place at 35.7 degrees Celsius (96.2 degrees Fahrenheit) on Wednesday, the highest-ever temperature recorded for June in the country, weather forecaster Paulius Starkus told AFP.

Scientists say the extreme weather is in part a result of climate change.

"Lithuania used to have heatwaves but now they occur more often and are more intense due to climate change," Vilnius University climatologist Donatas Valiukas told AFP.

Fellow Baltic state Latvia is also experiencing unusual heat for June, with temperatures over 32 degrees Celsius.

In recent days, Latvia's western region of Kurzeme saw thunderstorms with hail damaging buildings, smashing greenhouses and tearing power lines.

Fellow Baltic state Estonia had a heatwave last week and is now experiencing rainy and windy weather.

Poland has also been experiencing high temperatures this month, which has resulted in increased air-conditioner use. The power transmission system operator PSE said that on Wednesday there was record electricity demand for a summer morning at nearly 24.10 gigawatts (GW).

Kuwait and Saudi Arabia Record Highest Temperature on Earth   
https://gulfnews.com/amp/world/gulf/kuwait-and-saudi-arabia-record-highest-temperature-on-earth-1.1560325581417

Increasing respiratory disorders in the UAE are growing more common in hotter months because the body’s internal thermostat finds it difficult to regulate the drastic change in temperatures.   

Dubai: A man died in Kuwait yesterday as the country reels from a heatwave. The man, who died because of a heatstroke, was found with his tools next to his body.

Kuwait on Saturday recorded the highest temperatures in the world; reaching 52.2 degrees Celsius in the shadows and 63 degrees Celsius under direct sunlight, according to Al Qabas newspaper. In Saudi Arabia, the mercury rose to 55 degrees Celsius in Al Majmaah at noon.

The heatwave is expected to continue well into the summer season, which officially kicks off on June 21. Arabia Weather website stated that the heatwave has also struck Qatar, Bahrain and the UAE, with the heat being accompanied by a high humidity rate.

Meteorologists in Kuwait have predicted a volatile summer this year, noting that temperatures could reach 68 degrees under the sun next month.

In Iraq the southern province of Maysan recorded a 55.6 degrees Celsius.

... As one of the hottest countries in the world with around half of its terrain covered in desert, Iraq is no stranger to stiflingly hot summers.

But even by its own standards, this June has been a sizzler—averaging a daily 48 degrees Celsius (118 Fahrenheit), compared to around 40 in previous years.

... Further south in the oil-rich province of Basra, the heat has reached life-threatening levels.

Oil companies have hoisted purple flags above their facilities to signal the highest possible danger levels for those working on the fields given the heat wave.

... The United States has granted Iraq another 90-day waiver to continue with vital energy imports from neighbouring Iran despite re-imposed sanctions, a government source said Saturday.

The extension came after "long discussions" with Washington ahead of a looming deadline on a previous extension granted in December, the official, close to the negotiations, told AFP.

Iraq pipes in up to 28 million cubic metres of Iranian gas a day for power generation and also directly imports up to 1,300 megawatts of Iranian electricity.

....With temperatures set to rise further in the weeks ahead, government officials are bracing themselves.

"The heat is reaching levels we haven't registered since 2011," says Amer al-Jaberi of the state meteorological office.

"It's going to be a hot summer," says Jaberi.

52˚C = 126˚F
63˚C = 145˚F

Yes, SH.

Years ago in the Australian Outback (IGC 1976) - during a fieldtrip in the Kimberleys, it was particularly hot one day and we were later told it was 54ºC (in the sun [i.e., not an 'official' temperature]) in a nearby town.  We walked a couple kilometers along a (flat) streambed, and almost nobody had any interest in the geology after a few minutes.  It was just a trudge to get to where our bus went after dropping us off.

I think this is meaningless. The temperature of the thermometer in sunlight might well reach 145F, but who cares? It does not mean that the air or anything else will be that temperature. The thermometer will heat up very quickly when exposed to direct sunlight, so it could be much warmer than the ground or the air.

Pretty sure what kills people is the wet bulb temperature, not the temperature in the sun. All they have to do in the latter is just to seek shade.

While you are "pretty sure", you are not really correct here. To determine heat stroke threat, the NWS uses the Heat Index, which is a regression that includes both temperature and relative humidity. It is distinct from a dewpoint calculation, see:

https://www.wpc.ncep.noaa.gov/html/heatindex_equation.shtml

Hot and dry environments with a suitably high heat index would have a low dew point yet would still present a high heat stroke threat.

Also note that "All they have to do in the latter is just to seek shade" is not very good advice given how rapidly heat exhaustion can present and how much it affects your physical and cognitive abilities.

In Iraq the southern province of Maysan recorded a 55.6 degrees Celsius.

..

This is an erroneous reading. It shows up still on Ogimet as the 12Z reading that day.

It was disregarded and the max for the day was 46.2 C

I challenge you to take an IQ test sitting in forty degree heat right under the sun at lower latitudes. Or go ahead go physically demanding work. When it is hot enough even walking under the sun is painful and challenging.

The human body is an engine that runs at an operating temperature of 37C. This temperature must be maintained or the human engine breaks down. The optimal temperature for the human engine is 20-24 for low activity and colder than that for high activity.

For the case where environmental temperatures are higher than optimal, the cooling method the human engine uses is sweating. Sweat can remove enormous amounts of heat. If you keep loading the human body with water it can withstand very high temperatures for a long time. 

However if the body is not watered, the temperatures are too high or humid, or activity level is too high, sweating may be overwhelmed and the body overheats.

Once the body exceeds safe operating temperatures it overheats and activity ceases.

Not to be dificult but I don't blame him. I once was helping someone move the temperature was 43 C and we were moving them up two flights of stairs. After a bit everyone else left and I didn't even realize it. Apparently I was working alone for about an hour and half without rest or water. When they asked why I didn't take a break or stop I was confused by the question and couldn't answer. My ability to think was just gone. If someone hadn't stopped me when they did I probably would have died that day. Now I know I have to hydrate and rest on hot days before I feel I need a break.
