At around Midnight, almost without fail, it is cooler than at Noon. Sometime after Dawn it begins to warm, progressively getting warmer and warmer throughout the daylight hours, until around 6:00PM when the temperature stabilizes and slowly starts to decline.
I have two theories as to what's going on here.
1. The clocks are causing Global Warming. If we change the clocks to only show the hours 7 to 10, we could capture the hours of the most moderate temperatures of any average day and avoid the extreme average daily heat and coolness of the other hours.
2. While watching both the clock and the thermometer, I also notice that they both become easier to read when that big bright yellow things is visible in the sky and harder and harder to read as that same glowing ball goes away every night. I'm not sure if the big glowing ball has any effect on temperatures as I am concentrating on studying the clock right now, but maybe there can be a relationship to my Time vs. Temperature Change ratio.
It’s simple. When it is dark you turn on your lights. Light bulbs cause global warming. But of course it doesn’t happen right away - there is a lag time. I’m sure that some scientific calculations could be made, but suffice it to say that the global warming is only observed until AFTER you turn the lights off.
Of course when you turn on the lights on again in the evening they are USING energy, which leaves less energy available to heat the earth, so a momentary cooling effect is observed, until of course the global warming kicks in again the next day after you turn the lights off.
