After searching, I found
"UTC relies on atomic clocks for precise timekeeping, unlike Earth’s rotation9. Since 1972, 27 leap seconds have been added to UTC to fix the Earth’s slowing down9. This keeps civil time in sync with atomic time.
But, global warming makes the Earth’s rotation speed up, possibly needing negative leap seconds9. By 2029, UTC might need a negative leap second, making minutes last 59 seconds."
After more searching
It seems some say the earth is usually slowing down
The earth is speeding up (
But I have a question
What does your post even mean?
And it seems earth normally gets slower but global warming is speeding it up
So...
Global warming is bad seems to be your point
