Freeman Dyson: Climate Change Predictions Are “Absurd”

One of the most prominent scientists to express doubts about climate change scenarios in the future is the physicist Freeman Dyson, who responds to critics in two videos on Big Think. 

 

“We don’t only have to worry about warming,” the physicist argues. “It could very well be the climate gets colder. Nobody knows”—and we waste time arguing when we should be preparing.

In the video below, Dyson talks about how he has responded to critics. When the physicist expressed reservations about climate change, he stirred heated controversy. “It doesn’t disturb me at all,” he says.

​Is science synonymous with 'truth'? Game theory says, 'not always.'

Good science is sometimes trumped by the craving for a "big splash."

  • Scientists strive to earn credit from their peers, for grants from federal agencies, and so a lot of the decisions that they make are strategic in nature. They're encouraged to publish exciting new findings that demonstrate some new phenomenon that we have never seen before.
  • This professional pressure can affect their decision-making — to get acclaim they may actually make science worse. That is, a scientist might commit fraud if he thinks he can get away with it or a scientist might rush a result out of the door even though it hasn't been completely verified in order to beat the competition.
  • On top of the acclaim of their peers, scientists — with the increasing popularity of science journalism — are starting to be rewarded for doing things that the public is interested in. The good side of this is that the research is more likely to have a public impact, rather than be esoteric. The bad side? To make a "big splash" a scientist may push a study or article that doesn't exemplify good science.

People who constantly complain are harmful to your health

Could you give up complaining for a whole month? That's the crux of this interesting piece by Jessica Hullinger over at Fast Company. Hullinger explores the reasons why humans are so predisposed to griping and why, despite these predispositions, we should all try to complain less. As for no complaining for a month, that was the goal for people enrolled in the Complaint Restraint project.

Participants sought to go the entirety of February without so much as a moan, groan, or bellyache.
