Bad science is bad science. The things you mentioned above have been rejected because...well...it was sh!tty science. This global warming topic is a very complicated issue and there is evidence to support a side. The unfortunate issue is the involvement of politics in something that really should not have an agenda.
It's still garbage science since there is evidence that data was manipulated to further an agenda. Science may be neutral or fact, Scienctist are men/women and have their biases.
We are witnessing bad science since it has been politicized and there is a clear agenda. If the Nazis win, the myth of their science would be taught as that, science. Hindsight is 20/20 and we can say these things now looking back 60 years later.
We live in a propanganda world and in that vortex of Climate Change talk and the conference in Durban, SA at the moment. People are referred to Climate Deniers akin to a Holocaust one and the difference is the side that is pushing this agenda is acting as if the debate is over. Carbon tax credits and offsets galore. It's a non starter and irresponsible of government or anyone to act if this is settled within the community.
