This question. Is making a question out of a sentence. Here is a graph of the global temps over the millennia.

The second largest: Orthodox

Poland has been Catholic for a long while and since the Church is an ecclesiestical institution, it plays no big role in trade. The Soviet Union had a very protective attitude towards its products and only a few categories of them were exported; it is quite possible that exports dropped during this period. THe Warsaw Pact marked a significant counterpoint to the NATO initiative but most countries were already good trade partners to the Soviet Union (and again, the pact was not about trade). The right answer is European Union; the open borders and the influx of technology has increased the potential for exports from Poland.
