Which way to the beach?
Increase in global temps leads to melting of ice on earth
Causes a rise in sea level
Causes a shift in coastline position

Why worry?
•Regardless of what is responsible, climate is changing
•If people contribute, how much does it influence it
•Only one earth- Let’s not mess it up for our kids and grandkids!
•If people do not contribute- what THEN!? Yikes!
•Can we stop the earth from becoming intolerably warm?
Can technology prevent catastrophic change?
It probably could given enough time and money
•unfortunately- Not enough time or enough money!
