Into this waver-thin layer of air we add every year over

Regardless of model predictions it is safe to assume that such an
amount of yearly emission must have some impact and that
at some time this impact will become irreversible. In 2004 Science magazine conducted a review of 928 papers published between 1993 and 2003 in refereed scientific journals. They found that none of the 928 papers disagreed with the current scientific consensus that human activity is significantly affecting global climate change. |
