There are emerging technologies that could cut the energy required for air conditioning by an insane degree. You'll hear about them in a year or so
Our World in Data@OurWorldInData

✍️ New article: Billions of people have access to far less electricity per day than is required to run an air conditioner for just one hour. For five months of the year, temperatures in South Sudan’s capital, Juba, climb above 35 degrees Celsius (95 degrees Fahrenheit). These temperatures are punishing for anyone, but particularly here, where air conditioning (AC) cannot offer any relief. While people in richer parts of the world can switch on their ACs, for billions in energy-poor countries, there is little electricity available to power a fan or an air conditioner. We can see this by comparing how much electricity people use at home on a typical day with how much power an air conditioner requires. Let’s consider a typical single-room air conditioner that uses around 1,000 watt-hours of electricity in an hour. In at least 45 countries, the average residential electricity use per person for an entire day is less than the electricity that is required to power an air conditioner for one hour. In the chart, you can see for how long the average person could run an air conditioner across a selection of these countries. In India, the daily electricity budget is sufficient for only 44 minutes of AC. In Nigeria, just 13 minutes; and in South Sudan, just 4.4.

For about a decade, I’ve been showing these two slides at conferences. Two hunter-gatherer populations (Hadza and Tsimane), likely the closest living humans to our Paleolithic ancestors. Diet: • 65–70% carbohydrates • 15-20% protein • 10–15% fat • ~13% lower daily caloric intake than the US population Daily movement: • 115–135 minutes per day • 6–12 km of walking Health outcomes: • Obesity: ~2% • Type 2 diabetes: ~1% • Cardiovascular disease: among the lowest ever observed This is not a low-carbohydrate population. The difference is metabolic fitness. When mitochondria are continuously stimulated by daily movement, carbohydrates can be oxidized (burnt). When movement disappears, fuel oxidation fails and metabolic disease emerges. The debate should not be low-carb vs high-carb. That debate has failed to solve obesity or type 2 diabetes for decades. The real question is: Can your mitochondria still do their job? #MitochondrialFunction #MetabolicFitness #MetabolicFlexibility #PhysicalActivity

@Ross_Hunt @DrAndyGalpin The actual article talks about excessive exercise leading to lactate which does not necessarily imply excessive lactate. What is the definition of excessive exercise in this case?

Get a good workout in today, and you'll be smarter after. Lactate enhances cognitive function. As covered in this new review, HIIT (high-intensity interval training) is particularly helpful in increasing acute cognitive function - in part because of its ability to rapidly generate lactate. In fact, lactate is now being described as "the first myokine".

@ClimateInstit There is also an assumption about strong methane management which just got weakened under the MOU.

A new report on Canadian LNG and oil exports rests on highly questionable assumptions about the global emissions impacts of these fuels and lacks transparency on the modelling inputs used. Here’s a brief explainer 🧵⬇️ ppforum.ca/publications/r…

Closed loop (@Eavor) and enhanced geothermal (@fervoenergy) technologies, both of which are now operating commercially, can expand geothermal from a gigawatt-scale resource available in just a few places to a terawatt-scale resource available practically everywhere. One of the most exciting developments in clean energy of the past two years!

Human rights and nature are the perennial enemies of profit.  Societies which fail to see this are on a path to lose all of their human rights, and all of their natural environments.

@MPelletierCIO Why does Carney not get it from your perspective. Surely he gets this as he used to do what you are doing.

Had a lengthy meeting today with one of the largest private equity funds globally. Canada is nowhere in regards to making it an attractive jurisdiction for deploying capital especially in the rapid built out of data centers. Excess regulations - more so than Europe - high taxes, and a lack of domestic power capabilities needed for scale. In a nutshell, we are missing out on this once-in-a-lifetime global trillion dollar infrastructure trade.

Good morning with good news: "China's CO2 emissions have been flat or falling for 18 months!" Transport CO2 fell 5% & electricity CO2 is flat (despite strong demand growth) in Q3 2025, compared to 2024. Solar surged 46% & wind 11% in Q3 2025! carbonbrief.org/analysis-china…
