Global warming can: cause a rapid rise in sea level Reduce the amount of land for crops Increase temperature of the air The methane gas that is trapped under the ice could be released into the atmosphere having bad effects on the environment Effects on the World • Animals are becoming extinct in some areas • Increase in air temperature may cause health problems • Glaciers are melting • Sea level is rising causing coastal areas to disappear How You Can Make a Difference • Recycle • Turn off lights • Use cloth bags • Carpool • Have a small car Resources • Time for Kids, www.timeforkids.com • Climate Change Kids Site, http://epa.gov/climatechange/kids /cc.html The End
