If you listen to American media a lot you may hear the term "Junk Science" being used by various pundits.(informed commentators)
The phrase Junk Science became popular in the past 20 years or so, and refers to scientific data or analysis which some group of people feels is inaccurate. It is therefore labeled as "Junk" (garbage).
These scientists or commentators associated with the Republican Party in the US are especially fond of labelling any science which doesn't fit their philosophy or agenda as Junk Science.
This might be scientific data about climate change ("global warming"), or anything associated with the environment, such as the melting of Arctic ice, or disappearance of animal species. (G.K)
