".....Support from Joseph Stalin gave Lysenko even more momentum and popularity. In 1935, Lysenko compared his opponents in biology to the peasants who still resisted the Soviet government's collectivization strategy, saying that by opposing his theories the traditional geneticists were setting themselves against Marxism. Stalin was in the audience when this speech was made, and he was the first one to stand and applaud, calling out "Bravo, Comrade Lysenko. Bravo." This event emboldened Lysenko and gave him and his ally Prezent free rein to slander the geneticists who still spoke out against him.
Many of Lysenkoism's opponents, such as his former mentor Nikolai Ivanovich Vavilov, were imprisoned or even executed because of Lysenko's and Prezent's denunciations.
On August 7, 1948, the V.I. Lenin Academy of Agricultural Sciences announced that from that point on Lysenkoism would be taught as "the only correct theory". Soviet scientists were forced to denounce any work that contradicted Lysenko's research.
Criticism of Lysenko was denounced as "bourgeois" or "fascist", and analogous "non-bourgeois" theories also flourished in other fields in the Soviet academy at this time (see Japhetic theory; socialist realism).
Interestingly, perhaps the only opponents of Lysenkoism during Stalin's lifetime to escape liquidation came from the small community of Soviet nuclear physicists: as Tony Judt has observed, "Stalin left his nuclear physicists alone... [He] may well have been mad but he was not stupid."....
...From 1934 to 1940, under Lysenko's admonitions and with Stalin's approval, many geneticists were executed (including Isaak Agol, Solomon Levit, Grigorii Levitskii, Georgii Karpechenko and Georgii Nadson) or sent to labor camps. The famous Soviet geneticist Nikolai Vavilov was arrested in 1940 and died in prison in 1943....."
It would appear that it is Barry that is not respecting the science of Climate Change.
Why is he such a Denier?
The U.S. State Department gave a vote of confidence to the Keystone XL pipeline on Friday, saying in a report that it has no major environmental objections to the construction of the megaproject.
The report says development of the massive pipeline to move oil from Alberta to refineries on the U.S. Gulf Coast won’t significantly increase the rate of oil extraction and release an unacceptable level of greenhouse gases.
“This is the fifth federal study on the environmental impact of the Keystone XL pipeline. Each previous one has stated that building Keystone XL would not adversely affect the environment,” Oliver said.
