What you have to remember is that there are FAR more research projects, using Federal funding, that are run with correct scientific methodology and impeccable ethics. The problem is ethics. At its root, the "climate science" people mostly get their ideology from green leftists, who like all leftists HAVE no ethics except to promulgate socialism by any means necessary.
"In a way though, it's pointless to debate a chicken and egg problem. If I give my junkie sister money and she buys drugs with that money, is the problem the money or the sister, or both?"
The sister.
You don’t see any “ethical” problems with giving money to a junkie or IPCC? I do.
