global warming. are we heading to a mini ice age era?

everybody have heard about the effects of global warming on planet earth. but in recent studies, many scientist explain that it is not the human being and his pollutants, what is affecting the planet. that only represents a small part. they make reference that what we are living on the planet right now is one of the many cycles of planet eart through its existence. because human life is too short, we do not stay on the planet too long to see its effects.

people everywhere should be concerned, but the clarion call is for the youngster to hear it.

some russian scientist has stated that the last mini ice age era was in the 1700's and people survived. they had a brutal winter in europe. even the thames river in london, partially frozen, but humanity knew how to keep on.

that is the lesson. humanity must take consciousness and prepare for a cold future, not a warm one.

the story is told by a young girl who loves reading journals and listening to radio. she seems as an attentive and joyful girl. however, when the story unravels later this turns out to be upside down. she is actually a naive girl.  

she meets with a boy while skating and he tells her that will call her. the problem of the story epitomizes here because he never calls and she acknowledges the fact that she is not a foolish. indeed, her communication with the boy identifies their relationship after all. it is somehow the struggle between emotional and physical engagement which we can only observe the latter one from the boy’s side. so that, the conflict is disclosed how it has been presented in the beginning where the girl believes that she is not a fool. the reader questions her self-confidence and understanding, as well as her sincerity.
