The envirowackos started the trend of co-opting science to fit their own agenda, supposed scientific research is no longer reliable.
The adkins diet situation is a prime example. A medical sounding group comes out condemning the diet with warnings about all sorts of dire outcomes and it turns out that it is a front for PETA.
The thimerosol problem with innoculations for children was also tainted research because of the same reason, 6 of the 10 researchers had a vested intrest in slanting the research. The other researchers disavowed the conclusions.
The big global warming project presented to the UN that was the basis for KYOTO was bunk. There was a huge group that was conducting independent projections. Another group wrote the consensus opinion consolidating the projects. The group took all the disenting opinions, threw out their data and then included the disenters as being proponents.
The latest breast ca/abortion study was tainted. The consolidatory that supposedly looked at all the available research study's to date threw out accredited study's that proved a link and included non accredited studies that didn't and then issued the edict of no link.
Science has become politicized that there is very little real research going on in a university setting. The private research that is going on, gets mud slung at it by the lefties because industry is supporting it.
The enviros weren't the first; and they won't be the last. Long before them, the Marxists claimed (and still claim) to have a "scientific" view of history. I suppose astrologers claim to be "scientific." Sociologists and similar "social scientists" say their stuff is scientific. So too with the creation "scientists." It's an old story.
Kyoto is even more tainted than that. By itself reducing carbon emissions would be a laudable goal because of local pollution from fossil sources, but the nonfossil replacement sources specifoed in the Kyoto treaty explicitly eliminates the nuclear option. This was put in to get support from European greens. For this reason, even Kyoto's own country, which depends heavily on nuclear, rejects the treaty.
