Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change? 1. where on earth has the population decreased in the last decade? 2. what is the average cost of a college education per person? 3. by what rate has the melting of glaciers increased? 4. where are the average temperatures changing on earth? 5 if the global climate is warming, why were there record-breaking cold spells last winter?

Climate change is any remarkable long-term change in the weather of a region (or the whole Earth) over a considerable period of time. Climate change is about abnormal variations to the climate, and the effects of these variations on other parts of the Earth.                                                                                    

From the definition above, questions 3, and 5 are clearly related to current evidence on climate change.

Question 4 seems related too however, it speaks to average temperature change. Temperature change may be an evidence of climatic change if it occurs to a great degree over a long period of time. So the phrase "average change" is neither here nor there.
