Automobile exhaust contains chemical compounds that mix with water vapor to produce _______. acid rain 3. Climate models predict future weather patterns will have increasing number and storms stronger ____________. sunspot activity on the sun may be Cycles of __________ to be responsible for changing climate. This could become a theory when enough evidence is collected to 4. convince most atmospheric scientists. 5. Increased burning of ______ fossil fuels by people in the last 50 years has made carbon dioxide levels change. 6.
