In the future, only the rich will be able to escape the unbearable heat from climate change. In Iraq, it’s already happening
Quote
A United Nations report released last month warned that the world is heading for a “climate apartheid” scenario, “where the wealthy pay to escape overheating, hunger and conflict while the rest of the world is left to suffer”.

In Baghdad, that is already a reality. On 48C days, which are now coming earlier in the year, air conditioners are the most effective way of staying cool. But an electricity crisis in the country is putting even that essential tool out of reach to low-income families.

The crisis – caused by a combination of corruption, mismanagement and a creaking national grid – has exacerbated the country’s energy divide. The result is a huge gap between electricity supply and demand, especially in the summer. A diesel generator can be used to meet some of the shortfall, but running an air conditioner from a generator is a luxury only a few can afford.

“The electricity is completely unpredictable,” says Abu Ahmed, a metal shop owner just down the street from Muhammad. “Sometimes it comes on at 10am and lasts all day, sometimes it’s only one hour. The air conditioner is out of the question without the government grid."  ...

Those temperatures are killers!


We operate internally at ~ 98 F and regulate our temperature by evaporation of water.
When wet bulb temperatures approach internal body temperatures it's increasingly difficult regulate body temperature. Our bodies simply overheat even when we're lying still.


Wet bulb temperatures need to be included in all weather reports/forecasts.
A/C isn't a luxury, heat stroke will cripple or kill.

Dangerous Heat Grips Wide Stretch of the South and Midwest
https://phys.org/news/2019-08-dangerous-states-south-midwest.html

Forecasters are warning of scorching heat across a wide stretch of the U.S. South and Midwest, where the heat index will feel as high as 117 degrees (47 Celsius) in some spots.

Parts of 13 states on Monday will be under heat advisories, from Texas, Louisiana and Florida in the South to Missouri and Illinois in the Midwest, the National Weather Service reported.

Some of the most oppressive conditions Monday were being felt in Louisiana, Arkansas, Mississippi and Oklahoma, forecasters said.

It was expected to feel like 116 degrees (46.7 Celsius) in parts of eastern Oklahoma, near Tulsa, on Monday, forecasters said. And parts of Arkansas just west of Memphis, Tennessee, could see heat indexes Monday of around 117 degrees (47.2 Celsius).

... "It feels like hell is what it feels like," said Junae Brooks, who runs Junae's Grocery in Holly Bluff, Mississippi.

In the Mississippi Delta region, farmers did not have a choice but to work in the fields Monday since they're scrambling to make repairs and get caught up after floodwaters inundated the region in recent months. The flooding—which involved an area larger than New York City and Los Angeles combined—has recently receded and the farmers are just now able to reach their land and begin cleaning up the mess left behind.

"The mosquitoes the gnats, the spiders, the snakes—all of them—have been way worse this year," Brooks said of the land known locally as the Yazoo backwater area.

The region hardest-hit by this week's heat wave could experience many more days each year when the heat index soars as the effects of climate change increase, scientists say.

New research shows that summer temperatures can vary as much as 20 degrees across different parts of a city, with poor and minority neighborhoods often bearing the brunt.

Energy Emergency Declared Amidst Texas Heat Wave
https://www.kwtx.com/content/news/Energy-emergency-declared-amidst-Texas-heat-wave-540437911.html

AUSTIN, Texas (KWTX) The operator of the electric grid that serves most of Texas has declared an energy conservation emergency as temperatures across much of the state approached or exceeded 100 degrees.

The Energy Reliability Council of Texas appealed to all of the state's consumers of electric power to limit and reduce their usage during the peak demand hours of 3 to 7 p.m. Tuesday after reserve capacity fell below 2,300 megawatts.

A megawatt is about enough electricity to power roughly 200 homes running air conditioners during hot weather

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

Power Blows Past $9,000 Cap in Texas as Heat Triggers Emergency
https://www.bloomberg.com/amp/news/articles/2019-08-13/texas-power-prices-briefly-surpass-9-000-amid-searing-heat

Electricity prices briefly surged past a $9,000 a megawatt-hour price cap in Texas as extreme heat sent power demand skyrocketing and forced the state’s grid operator to declare an emergency.

As temperatures in Dallas climbed to 103 degrees Fahrenheit (39 Celsius), the Electric Reliability Council of Texas issued an emergency alert, calling on all power plants to ramp up and asking customers to conserve. At one point on Tuesday afternoon, the region had just 2,121 megawatts left in power reserves, less than 3% of total demand on the system.

... ERCOT has said its planning reserve margin for this summer was a historically low 7.4% because several generators have been retired even though demand is rising

Lower power prices make it difficult for some generators, like those operating old coal-fired plants, to make money selling electricity.

Heat waves like the ongoing event in the Southern Plains and Gulf Coast are becoming increasingly humid, which makes them more dangerous to human health.

A Weather Station Above the Arctic Circle Hit 94.6 Degrees Fahrenheit
https://earther.gizmodo.com/a-weather-station-above-the-arctic-circle-hit-94-6-degr-1837274379

According to data released in the National Oceanic and Atmospheric Administration’s (NOAA) monthly climate analysis, a weather station in Sweden north of the Arctic Circle hit a stunning 94.6 Fahrenheit (34.8 degrees Celsius) last month.

... The steamy temperature was recorded on July 26 in the small Swedish outpost of Markusvinsa, which sits on the southern edge of the Arctic Circle. Deke Arndt, a NOAA climate scientist, said on a call with reporters that the data was analyzed and quality controlled by the Swedish Meteorological and Hydrological Institute and that “they have established that as highest temperature north of the Arctic Circle” for the country. For comparison, the hottest temperature recorded in New York City last month was 95 degrees Fahrenheit (35 degrees Celsius).
