Bear poops in woods, some observers say
Check out the "story highlights" on top of this CNN piece:
• World’s poor are disproportionately affected by climate change, analysts say
• Low-income groups have comparatively little influence on public policy
• Burden of climate change rests with wealthy individuals, some observers say
Interesting that "some observers" are the only support for that third bullet.
What if you added a first premise: "Wealthy individuals are responsible for a disproportionate amount of total greenhouse gas emissions." (Princeton’s Stephen Pacala says the world’s richest 7% are responsible for 50% of GHGs.) Then doesn’t the last bullet follow from simple deductive reasoning? No observers necessary.
