Goofs

Much of this episode focuses on leaded gasoline as a significant contributor to atmospheric lead content. However, it is incorrectly implied that leaded gasoline was phased out as a result. In reality, it was the widespread introduction of catalytic converters in new automobiles starting in 1975 that drove the switch to unleaded gasoline. See more »

great show
1 April 2015 | by See all my reviews

Brian - no - Neil believes in science not global warming. It just so happens that 99% of all scientist believe in global warming... And any good scientist will change his mind if someone can present the information that suggest something different. so yes - he believes in the scientific data and studies that strongly suggest global warming is happening and most likely caused by CO2 pollution tied to man's burning of fossil fuels.

Neil believes there is a parallel between lead pollution denial and CO2 denial. Looks pretty obvious to me. Willie Soon is your deceiving "scientist" of today - paid highly by the coal and petro corportions to sew seeds of doubt - just like the "evil" characters in the clean room episode.

If you choose to ignore the facts - many many people will be affected. Just like in the lead poisoning case.
