HEAT Waves 2018

Finally, it looks like our turn!

It looks like we just might get to join the party this year. Forecast is for Calgary to break its high temperature record of 36.1 C set in 1919, maybe, possibly, if it's not too smokey from those BC forest fires. That's right a 99 year record, never mind why it was so hot a century ago or why it's taken global warming almost a 100 years to show up, we are going to party like its 1919 this weekend if the record goes (ps no deaths due to heat are expected we are not Montreal).

That is indeed hot weather, but if the forecast you linked to is accurate in the details you will have a nice steady breeze which can make a heck of a difference in personal suffering. It also appears your humidity is quite low, which is a real blessing on those hot record setting days. Looking at the monthly function July was pretty mild and most of August is predicted to be the same outside of this heat wave so a little caution now and folks can enjoy the return to cooler temps in a week or so down the calendar.

We did it 36.5 C today a new all time record high for Calgary, 0.4 degrees C hotter than it was in 1919 (and 1933). Let the panic begin!

North Korea heat wave ‘potentially catastrophic’ as crops fail in heat: Red Cross

A heat wave in North Korea has led to rice, maize and other crops withering in the fields, “with potentially catastrophic effects,” the International Federation of Red Cross and Red Crescent Societies (IFRC) said on Friday.....
******************

Is North Korea the first nuclear H power to face catastrophic famine and maybe put the bomb on the table to get food?

Next will be Pakistan + India

Germany /Münster attempts fish rescue after heat wave lake deaths
Münster authorities have been pumping millions of liters of oxygenated water into the Aasee lake in an effort to save its fish population. Tons of fish have died after a recent heat wave led to a drop in oxygen levels.

'Heart attack'

The problem was compounded by the sudden rise in fish carcasses, which take up oxygen as they decay.

"The Aasee lake as an ecosystem has suffered a heart attack. We're now doing everything we can to help it recover," said Münster city spokesman Joachim Schiek.

Schiek confirmed that the majority of the fish in the lake had suffocated to death in the heated water.

The water injection is expected to last until Monday.

Halfway to Boiling: The City at 50C

It is the temperature at which human cells start to cook, animals suffer and air conditioners overload power grids. Once an urban anomaly, 50C is fast becoming reality

Imagine acity at 50C (122F). The pavements are empty, the parks quiet, entire neighbourhoods appear uninhabited. Nobody with a choice ventures outside during daylight hours. Only at night do the denizens emerge, HG Wells-style, into the streets – though, in temperatures that high, even darkness no longer provides relief. Uncooled air is treated like effluent: to be flushed as quickly as possible.

School playgrounds are silent as pupils shelter inside. In the hottest hours of the day, working outdoors is banned. The only people in sight are those who do not have access to air conditioning, who have no escape from the blanket of heat: the poor, the homeless, undocumented labourers. Society is divided into the cool haves and the hot have-nots.

Those without the option of sheltering indoors can rely only on shade, or perhaps a water-soaked sheet hung in front of a fan. Construction workers, motor-rickshaw drivers and street hawkers cover up head to toe to stay cool. The wealthy, meanwhile, go from one climate-conditioned environment to another: homes, cars, offices, gymnasiums, malls.

Asphalt heats up 10-20C higher than the air. You really could fry an egg on the pavement. A dog’s paws would blister on a short walk, so pets are kept behind closed doors. There are fewer animals overall; many species of mammals and birds have migrated to cooler environments, perhaps at a higher altitude – or perished. Reptiles, unable to regulate their body temperatures or dramatically expand their range, are worst placed to adapt. Even insects suffer.

At 50C – halfway to water’s boiling point and more than 10C above a healthy body temperature – heat becomes toxic. Human cells start to cook, blood thickens, muscles lock around the lungs and the brain is choked of oxygen. In dry conditions, sweat – the body’s in-built cooling system – can lessen the impact. But this protection weakens if there is already moisture in the air.

Not long ago, 50C was considered an anomaly, but it is increasingly widespread. Now, several cities in the Gulf are getting increasingly accustomed to such heat. Basra – population 2.1 million – registered 53.9C two years ago. Kuwait City and Doha have experienced 50C or more in the past decade. At Quriyat, on the coast of Oman, overnight temperatures earlier this summer remained above 42.6C, which is believed to be the highest “low” temperature ever recorded in the world.
... “We must hope that we don’t see 50C. That would be uncharted territory. Infrastructure would be crippled and ecosystem services would start to break down, with long-term consequences.”

Even under the most optimistic predictions for emissions reductions, experts say almost half the world’s population will be exposed to potentially deadly heat for 20 days a year by 2100.

Insensible before the wave so soon released by callous fate. Affected most, they understand the least, and understanding, when it comes, invariably arrives too late.

I foresee billions of PV panels, strategically located to provide shade and dedicated to cooling stuff. Cities already create their own heat domes. That will get worse as humans struggle to move heat from inside to outside. But that heat has to go somewhere.....
