Who Is Warming This Globe? Poem by M. Asim Nehal

The Teacher entered the classroom,
Everyone started to greet in loud voices,
The Teacher went straight to the blackboard and wrote:
"WHO HAS WARMED THIS GLOBE? "
There was pin drop silence as the teacher after writing
Started to move from one desk to the other
Glancing at each and every student.
Some were moving their head side by side
As if to say "NO" and some looked puzzled
As to when this incidence occurred
When the teacher stopped at one desk
The student immediately stood up and said
Teacher, I was down with fever for past 5 days
Today only I came to the class.
Teacher moved on and everybody thought
Teacher is looking for the culprit.
Teacher took a left turn and switched to next row
Kept walking past each desk back to the blackboard and wrote again "
"WHO…………". Pulled the chair and sat for a while glancing from first row to the last bench
Students were looking at each other as if requesting the one to accept if they have done it.
In all silence the teacher asked "Someone please close the doors".
This silence remained for a few more minutes and then teacher Stood and went back
To the blackboard and said: can anyone simplify this sentence and make it meaningful.
