In recent years, surveys based on social-science studies have been well applied to quantify the impact of heat stress on the work capacity. However, previous surveys were mainly for developed countries. The number of samples was usually very small (hundreds or even tens) and not suitable for identifying the regional differences across the world. The worldwide pattern of heat-related work productivity loss (WPL) remained unclear.

Recently, YU Shuang, XIA Jiangjiang and YAN Zhongwei from the Institute of Atmospheric Physics, Chinese Academy of Sciences, together with colleagues from China and UK, synthesized 4363 responses to a global online survey in 2016, the most extensive global survey about the effect of stress on the WPL currently available, in order to quantify the effects of on work productivity in different countries for the year.

The results show that the heat-related WPL for the year was 6.6 days for developing countries and 3.5 days for developed countries. The heat-related WPL has significant negative correlation with GDP Per Capita (cc=-0.63), indicating that the WPL is inversely proportional to the level of development. They identified the regions of vulnerability to heat waves that might have been overlooked in the past, especially the regions such as Central Asia and northern Europe due to relatively low adaptability to heat.

They further estimated the WPL for the future in the Representative Concentration Pathways (RCPs) scenarios( greenhouse gas concentration trajectory adopted by the IPCC and aims to represent the different atmospheric concentration change and climate futures). When global warming reaches 1.5, 2, 3 and 4°C respectively, the average WPL will be 9 (19), 12 (31), 22 (61) and 33 (94) days for developed (developing) countries. Countries in Southeast Asia in a 1.5°C-warming world would suffer the same loss as the developed countries would in a 4°C-warming world. This quantitatively addressed the severe situation that developing countries would face under .

"Heat waves surely impact more seriously the developing countries in general, but our study quantitatively estimated how much heatwaves would reduce the productivity and identified the most vulnerable regions over the world." YU Shuang said, "Our results call for attention to the need of adaptation to increasing heatwaves by improving protective infrastructure especially for the developing regions in the Belt and Road."

The paper was published in Journal of Cleaner Production.

You better believe it.

Watch where you step. Just more AGW Cult bullshit from their Pathological "science".

And wacko extremist climate change deniers (mentally challenged they must be) are stepping right in it.

I hope no USA taxpayer money went for this complete nonsense


Nothing but a stinking fecal regurgitation. We need a minimum intelligence test to post on this site.

I believe you have hit the nail squarely on the head and buried it. More reason for the minimum intelligence requirement..... ain't the celebration of ignorance, stupidity and fecal regurgitation wonderful?

Well, that a little wit and a sense of humor.

When I see people moving to Canada, Russia, Norway, Finland, Sweden, Alaska instead of farther south, then I will believe we don't need global warming. The Northern States and farther North are very hard to live in.

Oct 26, 2018
Gramps, you're moving the people will happen when it becomes that extreme. Immediate people movement will probably be based on economic conditions. Obviously.

Talk about insane.

The theory that the Southern hemisphere's people never advanced or created much due to them not having to work to fight against the cold for survival holds water. If the world was warming, it could very well reduce productivity.

Oct 27, 2018
Oh bag_boy, it is a good thing for you that you are safely swaddled and cared for as a perpetual infant by the efforts of a diversity of hard-working people who subsidize your useless existence. Especially as videogames are the only modern technology you are capable of mastering.

Dr Peter Ward has already pointed out in his books that heat stress rules productivity. He notes that the heated populated areas have all managed to develop a by pass to heat stress. he proposes the the cocoa and the betel nut among others are used to distract the mind from the heat stress.

Funny - I never heard that theory. Did you come up with it yourself? Sounds like a rationalization for some racism. Does that mean that people who populate the coldest areas - like Siberia, and polar regions are the most creative?

The southern hemisphere has just a fraction of the land mass of the northern hemisphere (even if we include Antarctica) and there simply aren't many people in the southern hemisphere, so it's easy to forget what the few people there have done. Thorium_Boy has forgotten, or has always been ignorant of, the work of the Inca, who created massive fortresses and irrigation systems using such carefully-crafted stonework that one can't slip a piece of paper between adjacent stones, or of the Nazca who created vast underground aqueducts and, of course, the enormous and enigmatic Nazca Lines. And this work was done in jungles and desert, the very areas Thorium_Boy is suggesting no work would get done in because of temperature.

Et decitur ex ignorantia. You have obviously never been north of the southern USA. You wear your ignorance as a badge of honor.

holy sh*tfire!

so... Apparently, NYC, Calgary, Seattle, Ottowa, Jersey, Montreal, Boston, Philly, Chicago, Toronto, Quebec City, DC, etc are all tiny bergs that are "very hard to live in"?

I wonder why so many people are there?

Too hot to work? Another good reason for leasing robots instead of hiring humans.

Its inevitable. Like all good ideas.

Robots are such a good idea that warming the planet on purpose in order to force their development would almost be worth it.

Because, we never produce anything useful unless we have to, you know? Lessee war or AGW, AGW or war hmmm what shall it be this time?

Ok AGW it is.

Actually, I'm glad you think that- hopefully it will keep you far away from these parts.

The Sun controls climate change. Alarmists are actually helping oil companies keep energy prices high. Oil companies love the alarmist green agenda. They know when all is said and done 80% of energy usage will still be petroleum based anyway. Imagine all the farm equipment that will still require oil for starters. Yes, a half a degree C increase change the past century, blame the Sun. And the plant food CO2 is not a poison, water is responsible for 90% of greenhouse gas effect.

Cap'n Stumpid brays.
Hey Stumps, despite being larger than the US, Canada has about a tenth of the population.

hey idiot f*ckwad russian anti-science trolling sock puppet

if you will note, I picked highly populated cities all over the North American *continent* (not the US, you idiot illiterate dipsh*t) that are all further north than Charlotte, NC

more to the point: I specifically named cities that, apparently, are *not* "very hard to live in" considering they're population puts them in the top 50 largest cities in the North American Continent (except Jersey... that is a state)

ROTFLMFAO

thanks for demonstrating your stupidity

How does Christchurch in New Zealand get to have a very high loss of productivity due to heat. It is a COLD place with a January (middle of summer) average temperature of 13 degrees C. On the other hand, lots of very HOT (and humid) places in the sub-tropics show minimal loss of productivity.
Let me guess. They sent a survey to some leftist social scientist who wanted to show solidarity with the workers so he reported how they suffered from the heat.
Can I suggest a better way - use measurable facts like temperatures, humidity etc instead of social science surveys.

I find that a quick check of google really helps to prevent me from making a comment that makes me look like an idiot. This study was based on (as the article says) days lost in 2016. The austral summer of 2015-2016 had an extreme heatwave in Christchurch with temperatures ~30C in February. That might cause more than a few days of lost work. Since a warming world would tend to make such events more likely, Christchurch will likely have to adapt to such events or continue to lose workdays.

HAWW...HAWW...hey idiot f*ckwad russian anti-science trolling sock puppet...HEE...HEE

And so, the StumPID jackass brays again.
Yes jackass, heat is the problem. That's why California has more people than all of Canada. It's why people flock to Vegas, Florida and the tropics for their vacations.
Hey jackass, have you ever been to Canada?
Summer is when the place comes alive. It's when the snowbirds, who headed south to escape the winter, return. Winter is when productivity drops, because of snow/ice covered roads, resulting in accidents. Ice on power lines cause them to topple. It's when people are hit with the flu. The list is too long for the shit between your ears to comprehend.
It is a tough place to live.
Keep braying jackass.

PS. The only risk to productivity, that heat poses in the cold north, is from people taking the day off to enjoy it.

And you think the current migration streams out of Africa are happening for shits and giggles?
