As the wikipedia article cites peer reviewed study (see study tab) that even though these kind of headlines make up only ~ 2 % of all hesdlines 44 % of them answer "yes", and only 22 % answer "no" with the rest being indecisive.
I think studies that look at the article's response are going to give a very different outcome than the real world result. The heuristic exists because a lot of news is overhyped halfsense trying to generate clicks (or draw eyeballs in the pre-digital world). So even if the article suggests a yes answer, a no outcome is still probably more likely.
No Canadian should be delusional enough to think their country's forestry is even cutting carbon emissions. There's a problem with first world energy use here
Funny because the guardian insisted for years that carbon capture is our only hope, meanwhile China was the only country cutting emissions despite manufacturing everything anyone on earth demanded
