Simply put, Pravda is not reliable for anything. I have seen the spamming on here the past couple of days. It's sad the sources people rely on to "prove" their preconceived notions.
Once a person decides on something they can always find sources to back them up.
Such disinformation is a scourge on society.
Edit: Some people seem to be greatly misinformed about "Russian Science". To say that Russian scientists are far ahead of Europe and the US is simply wrong. During WWI, WWII and the Cold War, Russian scientists excelled at engineering and physics having to do with military matters. They did not, by any means, greatly excel past any other industrialized nations. In the areas of biology and genetics, the Rusians were decades behind the rest of the world. They have done much to catch up, but as late as the 1990s hardly any scientific paper published by a Soviet biologist was received as serious work in the West. Soviet bilogists were found to be too ignorant of the world scientific literature, and in the case of geneticists, too prone to fabricate data.
Basically, using a Russian newspaper (Pravda) article, that is not based on climatology to somehow demonstrate that we are entering an ice age and that global warming is completely bunk, is so dishonest it is not even wrong.
