So, nothing about the reaction here is new at all. Calling it a new discovery or some ploy they just threw out because of convenient timing is simply wrong. This a very long standing debate and most public officials have a track record on their stance.
Second, your analogy of climate change and tobacco is flawed.
For starters, the media and government don't protest tobacco because not enough people care. Everyone is aware of the dangers these days, they just don't care enough to stop.
More importantly is you're comparing apples to oranges. Climate change is worthy of an accord because it is a global issue and affects Everyone! Smoking affects only a small area. Not saying they aren't an issue, but not even comparable to something like climate change.
Not trying to poop on your post, just a discourse.
