The article we're commenting on argues there's been a huge pressure towards researching ways to stop beta amyloid plaques; and yet there's no obvious "incentive" to do so. It's just a catchy hot topic on which many have invested their careers.
In the case of climate change, you have to factor in both the scientific pressure, similar in everything to what's been described here; and the media pressure, absent in the alzheimer's case: the media absolutely loves to sell a scare story, and the climate change story is just the perfect one: it's everywhere, it's invisible, it carries an enormous amount of consequences and huge risks. Most of the predictions are decades away in the future, so the story can go on unchecked for decades. And so on.
I'm not saying climate change science is wrong (although some of it certainly is: "climate change science" goes from the basic physics of CO2 greenhouse effect to ecology, economy and social and political predictions far away in the future). I'm saying that you must factor in all the inevitable effects of a story everybody just loves to tell.
