Confirmation bias and selective memories are at play here as well. Both sides appear to be involved.
I recall 50 years ago when we never experienced prolonged heatwaves like we do now, nor did we have as many heat-related deaths. However, comparing temperatures alone is akin to equating a car crash at 100 km/h today with one a century ago. While the speed may be similar, most would prefer to be in a modern car equipped with airbags and seat belts rather than a Ford Model T.
But when 40°C becomes the norm instead of the exception, that’s when we have a problem. And guess what? We’re there. Welcome to the new normal.
Interestingly, despite the clear evidence (reminds me of covid), there are still those who choose to ignore the problem. It’s like standing on the deck of the Titanic and arguing that the iceberg isn’t that big. But the ship is still sinking.
Landlords and stratas in older condos argue that A/C units strain their outdated electrical systems or detract from the building's appearance. If it's just a wiring issue, they could invest in rewiring the building, which is tax-deductible. But it's not. Many are simply drunk on control and power.
From what I've seen in this thread, it's folks with the same mindset (like local government, landlords, and stratas) who don't see the need for air conditioners. They say, "just use a god-damn fan". Similarly, some providers think the same way too.
