> Until about the 70s all the media, leading scientist and organisations were concerned about the impending ice age

no, not "all" the media nor all the leading scientists.. this is simply false

In the 70's we were still trying to get rid of lead in paint and gasoline while being concerned about the giant hole in the ozone.

Nonsense.

And you're still parroting it 50 years later?

Have another pack of death sticks and kick back with nine out of ten doctors sucking back cancer.
