It is the middle of Autumn now and the Day and night are equal length. In 2 days on Sunday the 27th, the clocks will go backwards one hour. So far there has been no morning frost. If there is no early morning frost by daylight saving then I will observe the rest of month and season and see if there is still no frost.
If there is no frost then it will be obvious there is a problem with global warming. And it will be obvious that the atmosphere has more energy trapped than before. Even to ordinary people like me.
