climate questions

• 1 - What do you think the global average temperature is?  This means the average for everywhere on Earth, day and night, for an entire year.  Explain why you answered what you did.
• I think is around 69-72º because its not too hot or too cold and i think most places have the same climate as us
• 2 - People are often talking about "global warming."  How much do you think the average global temperature has increased in the past 100 years?  Do you think that this is a lot?
• 2-3º and i think this is quite a bit because to think about it 2-3º every 100 years goes up pretty quick
• 3 - What do you think is the hottest the Earth has ever been? (since there has been an atmosphere?)  How about the coldest the Earth has ever been?  Explain why you answered what you did.
• 130º and -25º because you think back into the ice age and libya
• 4 - Are you concerned about "global warming?"  Why or why not?
• no because this temp change has been happening again for a long time and i think we are in another "warm" period
