Need to be careful taking headlines at face value. I'm guessing you saw the headline I did that actually said we'd surpassed the 1976 temperature for the first time for that specific week, of that specific month.
The peak temperature in 1976 was only 35.9°c .
The heatwave we had a couple of weeks surpassed that several days running. As have other heatwaves from the last 6 years alone.
The differences between now and 50 years ago are that we have heatwaves now that we suffer now and not limited to one small group of islands. They are not only more frequent, but of significantly higher temperatures for significantly longer periods of time.
15+ years ago, a typical heatwave last about 4 days. I used to complain that they could hardly be called such - how naive I was.
Heatwaves now tend to affect entire continents,not just the UK. Wildfires across continents and in the UK are becoming more vicious and alarmingly frequent.
We are woefully equipped for them in the UK. From the simple fact that most us are naturally pale, leaving us more vulnerable to the sun than those from the southern med who have more olive skin, to the facts that are transport systems and supermarket fridges are not designed to withstand this type of heat.
We're seeing trees suffer with heatstress from June - not just this year, but at least 2 others years since the covid pandemic.
Our water infrastructure is collapsing- we're managing it so poorly that we will be experiencing severe water shortages in years. This is whole the pour sewage into rivers and seas so thar we can't cool off without risking hospitalisation in a heatwave.
Our buildings aren't equipped for this heat. Hospitals and homes.
I realise my reply goes beyond the point you argued but it's imperative people realise the situation we're in - and it's only going to get worse. Britain is facing complete ecosystem collapse in near future - that means no food.
Much of our press is influenced/owned by those with vested interests in not addressing these issues and this means the headlines & commentators in most papers play the climate crisis down.
The old 1976 argument...It gets clicks and it's reassuring and whips people up against each other.
The heatwaves we experience now are NOT like those living generations grew up with. And not simply because of frequency.
