It was 21d C in Dubai yesterday and someone commented it was twice as cold as it’s in summer when it reaches more than 42d C.
Well, Not So . It’s only 7.1% hotter. Sun only has to shine 7.1% harder to make the temperature as 42 C ( angle). The problem is with our scale of temperature.
Let’s look at the temperature in Kelvin Scale to find the actual variation.
21 Degree Celcius is 294.15K
42 Degree Celcius is 315.15 K
Now you can see that it’s only 7.1% hotter.
