The public believes the effects of global warming on the climate are not as bad as politicians and scientists claim

Some scientists claim. Many do not It is not about skepticim over claims. It is science over fearmongering.

Not all the most important and famous scientists agree about climate changes and global warming (see for example the last annual congresses in Erice, here in Italy and precisely in Sicily). There's something true in psychological terrorism by the powerful mass-media often linked to politic and big industrial groups interests (don't forget that subliminal mind conditioning is still used in other modern ways as in some continuously repeated spots or information). People have learned this trough time.
But all this doesn't keep us out of the responsibility for the health of our living environment getting sick day by day.
