A fly roof to prevent heat build up and facilitate hot air to escape at the top of the building. Solar power means running aircon in the middle of the day doesn’t mean big bills.

Many people commenting here entirely missed the issue of the "wet bulb" temperature. That is the difference between just" really hot" and" killing hot".

[@MissFoxification]

I don't know why people see a 1 degree change as small.. it's nothing close to it. It takes 311 kilojoules of energy to heat 1 litre of water to boiling point from 25c and of course 311000 kj for 1 tonne of water. Now imagine how much energy is being absorbed into the planetary system to heat it up a degree.. and it's on the upswing. That amount of energy has to go somewhere, that is an immense amount of energy. 1 degree is massive and we're looking at surpassing 1.5.

[@r.a.6459]

[@brianwheeldon4643]

Scientists researching wet bulb temperature in 2022 had a peer reviewed paper released that showed wet bulb temperatures as low as 31ºC could be lethal. Very humid countries such as New Zealand often have relative humidity levels in excess of 80 percent rising to the high 90 oercentage levels at times. The north of New Zealand from Auckland ( latitude 36.6º south) is relatively narrow, often a few tens of kilometres or even less, surrounded by the Pacific Ocean and the Tasman sea. It naturally has high humidity and warmth. An uncomfortable place that can be lethal when caught outside without airconditioning. With marine heatwaves occurring increasingly regularly since 2016 the ocean has been a whole year in heatwave without break off the coast of the Bay of Plenty and in the Sourth Island sometimes in heatwave conditions for over 200 days. Thousands, likely millions of fish are dying under the water, we don't know how many, but thousands are frequently washed up the beaches in their death throes. Similarly the world's smallest Penguin, the fairy penguin has been starving, through lack of fish to catch and eat, and dying in the hundreds, washed up on beaches. Akin to us going to the supermarket and finding empty shelves due to heatwaves, droughts and floods. But as in England, the New Zealand Government is doing nothing to mitigate our use of fossil fuels while the Banks and the biggest corporations make huge profits counted in billions of $$. What a lethal cost this profit demands over the life giving conditions nature has provided for life to thrive which we are now in the process of destroying. The 'Human Niche' is at increasingly grave risk around the world.

[@DieFlabbergast]

It is FAR too late for cuts in fossil-fuel usage by Western countries to make any difference at all. Not when the "developing world" is continuing to pump out massive volumes of carbon dioxide. The focus of effort should be on developing technologies that mitigate the effects of hotter temperatures -- more efficient air-conditioning for homes & workplaces (governments must subsidise the costs for less wealthy people), and above all development of crops that will grow in higher temperatures. The world IS going to get hotter: WE must adapt.

[@robertsteinbach7325]

Exactly. People think "Oh, 3 degrees is nothing". What is really means is: years without winters so bug populations are out of control; summers with more heat waves and the heat waves being worse. No one thinks of heat waves being fatal but people die of heart problems and asthma made worse by heat waves. That is what an additional 3 degrees mean.

Wet bulb temperatures: 35 Celsius, 100% humidity deadly in 4 to 6 hours 47 Celsius, 0% humidity deadly in 4 to 6 hours Average temperature rise, 1C, on land masses 1.5 to 2.0C, inner continent is greater still, inner cities greater still (heat island effect). So an in land or inner continental city during a heatwave will see far more heat related death risks. Other factors include latitiude, how much water bodies and greenery there are in the area, how much shelter there is from topography, how well buildings regulate heat before using any cooling and how well those homes can be adapted for hot and cold. The amount of greenery and water you have today will not necessarily be what you have in 5 or 10 years time as loss of water and forest fires will see that decline. Also water bodies such as lakes don't mix too well at different depths so they become less efficient at absorbing heat as the heat wave persists but they will also evaporate increasing moisture and the risk of wet bulb temperatures. Many places will see more variation in the availability of water throughout the year. We could have more water flowing through our reservoirs throughout the year but if we can't store it we won't have it in summer. We also have huge declines in ground water around the world too with very little in the way of conservation for groundwater. Groundwater is a fundamental national reserve we neglect. Unfortunatly a lack of action now means we would need much faster adaptation in the future and many homes need adaptation for extremes of hot and cold.

It's not just the temperature, it's how long that temperature is sustained, and 'when' a heatwave occurs in a crop plant's growing season. If a heatwave occurs when water supplies are low and plants are young, you're in for some serious problems. I live in Scotland and, up to 3 years ago, our local climate was wet and cool for approximately 50 weeks a year. We would be guaranteed at least a little rain every day for those 50 weeks. That's changed. For the past 3 years, we have had extended dry periods throughout the mid/late spring to midsummer. Last year, for instance, we had no rain for 3 months. At one point, the temperature reached 31 Celsius in the shade. The effect on plants was devastating. Trees started to shed their leaves, like an early Autumn. New plant growth burned and withered away (I'm seeing the same thing happening now, again). Stressed fruit trees failed to produce much fruit, some none at all. Last week, I cut down 12 trees because they never recovered from last year's heatwave and drought. I'm now looking at 20 more trees that look like they're about to die because we haven't had anything like normal rainfall. Too hot, too dry, the soil is like dust, my well is dry, both my springs are dry, the stream dwindling rapidly, and I don't want to use mains water since I know the local town's reservoir is lower than normal too.

I live in Brazil and we are under the winter, but the temperature is really high for this period it around 27 Celsius degrees it may be around 15.

[@khurramkhurshed9427]

Alarming situation 😮

[@mohdazan4948]

Malaysia is currently in a heatwave as the average temperature year round is like 20°C - 30°C so its not that bad in malaysia, although we can’t do PE anymore outside of classes like the field

[@brentchristopher7363]

I was brought up measuring temperatures in Fahrenheit. Celsius throws me off. Is there an easy way to learn Celsius? When they say 36 degrees Celsius is hot, I have no idea idea how to convert it.

[@didierpuzenat7280]

One point not emphasized enough is that a global warming of 1.5 degrees means quite more in some places, eg 4 degrees in France. And sadly 1.5 degrees is becoming the ultra optimistic scenario. As many, I am doing my best to reduce my impact of climate warming, but at the same time I am taking actions to adapt even if it means consuming more energy and resources. For example, I have switched from gas to air/air heat pumps to reduce my emissions in winter *and* to have AC in all rooms for the whole family to deal with heat waves in summer. Having to adapt makes the challenge even harder, but we have no choice.

[@ChickpeatheTortie]

Its 15th September in London and it is still baking hot. Also noticed that the sun is way toooooooooo high in the sky - something that no-one seems to be talking about

[@anitagorse9204]

Major cities need to find solutions for summer months. People here who can't afford or have no way to install AC go to the shopping malls with AC and sit there during the day, mostly retirees during the weekend others too. In my city drinking fountains are being installed all over the place and new trees planted everywhere there is space. In summer months cooling places will have to be open. Some of the population will have to leave city for some months. The problem is you can't be always in one place all day. And there are construction and utility workers working in in the open whole day.

[@jean-pierredevent970]

It is the fastest solution as you describe it. I hope those malls have insulation and white roofs , so their aircon doesn't get to much load. But these are already there, no need to be build huge cooling centers. Perhaps people could sleep there too but the products need to be locked away of course. The government could pay for the inconvenience. It's normally not for weeks.

[@anitagorse9204]

@@jean-pierredevent970 Shopping centers either have green roofs or solar panels for their own electricity. Some have recreational facilities like swimming pools or outdoor fitnesses. If you cool down there's no need to be in the whole day.

, been really nice in Phoenix Arizona so far this summer spring.

Getting zeros here in Oz and it's not even winter yet. Interesting to see what summer brings. Record of 50 Celcius might be in danger.

[@alanj9978]

El Nino this year too, could be another big fire season. Best of luck to our friends down under.

[@reinapiratayquepaha]

​@@howickrccarmadnessit is, but it has a different effect. Some places will get more devastating heatwaves, others will have terrible blizzards, others still will get flashfloods of destructive proportion and so on. My country for instance isn't facing heatwaves to such an extreme, but we're dealing with the worst drought ever recorded.

[@Joytous]

I got hypothermia living in a caravan in central Victoria mid April. Solar backup went out so no heating. It was torture having just come from living in Cambodia for years where they where experiencing a heatwave.

no one talks about it but the comming 3 month of drizzeling rain is actually some kind of monsun in south europa

This summer cured any desire I may have might’ve had for helping put out darvaza. Their locals really might consider taking one for the team.

I almost wouldn’t believe a lot of the statistics, if it wasn’t provided by such a reliable source as The Economist. Downright shocking and worrisome. Knowing this is just the beginning of worse

The heat dome in bc 🇨🇦 was scary and i dont want to experience it again.

[@bugsalmudafar2973]

If you have room to plant a clumping Bamboo tree. I can honestly say it lowers down several degrees under and around it. I lived here in Central Fl. I know it's not allowed on a lot of properties but it does give a lot of shade and gives cooler temperature than any shade tree I know.

A serious question: Has The Economist analyzed and published a soul-searching review of its own -- and the economic profession, and capitalist -- reaction to those warning humanity about the danger of climate change in the past 40+ years? If not, would you kindly do so?
