atmosphere，7.causing (cause) the global temperature to go up.‎ On 8.the other hand，other scientists 9.like George Hambley believe that any warming will be mild with few bad environmental consequences and more carbon dioxide is 10.actually (actual) a positive thing.‎ Ⅱ.课文短文改错 I am doing a project on behalf of my school about global warming.Sometimes I felt that individuals can not have any effect
