Overview• Three weeks of related activities dealing

with greenhouse warming and energy– CO2 ArcView (today)– Climate Negotiation Role Play (next week)– Energy Arc View (after Spring Break)

• Today– Assess the global dimensions of CO2

– Begin preparation for Climate Negotiations

Trop 03

1. To expand our knowledge of global patterns of CO2 emissions

2. To increase our comfort exploring ArcView Data Sets

Climate Negotiations Role Play

• AOSIS – Chris, Whitney, Karen, Mark

• EU – Jordan W., Chester, Sam, John

• JUSCANZ – Nick, WangKi, Lauren, Jordan Z.

• G 77 – Megan, Jimmy, Marvin, Dawn, Amy

Goal: Negotiate an agreement to reduce greenhouse gas emissions to 7.5% below 1990 levels.
