What you state above ("*scientific consensus was that smoking was healthy for people.") has NEVER been true. You must be confusing false advertising with science
“More doctors smoke Camels than any other cigarette.”
Since the early 1950's, the consensus has been that cigarette smoking leads to fatal illness but due to almighty profit, cigarette companies waged an offensive against the scientific community and the unsuspecting smoker.
Tobacco was introduced to Europe from the "New World" in the late 16th century and by the early 17th century (1602 I believe), Dr Eleazar Duncon penned a letter about the ill-effects of smoking tobacco. There are many reports from the 17th and 18th century linking smoking to ill health as well.
Where on earth did you find that little nugget of untruth?
your example is perfect.
a few minds say smoking is bad but large public consensus thought smoking was good by enlisting alot of doctors who attributed their names to limited science and so public opinion..
because more were swayed to the limited science reports than the few minds that have been saying its bad
and thats how cigarettes became ok in governments eyes
it wasnt until decades later people started to wis up
we are still stuck in the 'more doctors smoke camel' era metaphorically
carbon dioxide is a concern for human health but water is a concern for climate.
its like when people talk about climate change then go on a tangeant about microbeads poisoning fish.
carbon is the microbead in that analogy
its far easier to handle the water cycle to cause more of a climate impact than carbon
and then separately handle carbon for the human health impact.
but yea. the argument will go on about 'things need to change' but years later after report and report are made all thats changed is the number of reports and debates.
untill the UN can actually start to come up with hard rules of tree's per populus area and water usage per farm and % of land permitted to be used. things wont change
some countries are already trying to make their couple decade old national strategies for other things appear as 'climate change' strategies to then pretend they are promoting climate change
some have said the whole 'farming quota' of the EU which sole purpose was to not have a food over supply (cheap food) are now making it a 'climate change' purpose. just to tick a fake box that they done something. although nothing really changed
because the whole finger pointing is just 'show you done "something" in a report' not actually 'do X'
take london. instead of actually cutting down on car manufacturing they just closed off traffic in certain area's whereby the closed off area becomes carbon reduced. but the result is more carbon on the other roads that have become more jammed up due to diversions which is not a combined net reduction. just a move it away from certain sensors to fake positive results
