Other top-level politicians do not express their global warming doubts because a whip of political correctness strangles their voice.

The largest threat to freedom, democracy, the market economy and prosperity, is no longer socialism. It is, instead, the ambitious, arrogant, unscrupulous ideology of environmentalism.

Climate alarmists believe in their own omnipotency, in knowing better than millions of rationally behaving men and women what is right or wrong, in the possibility to give adequate instructions to hundreds of millions of individuals and institutions and the resulting compliance or non-compliance of those who are supposed to follow these instructions.

The message of [Fahernheit 9/11] is very weak and propagandistic ... We were used to such messages in the communist days. Everybody has open eyes and can understand that this is propaganda. It was a weak film that tells us nothing new.

As someone who lived under communism for most of my life I feel obliged to say that the biggest threat to freedom, democracy, the market economy and prosperity at the beginning of the 21st century is not communism or its various softer variants. Communism was replaced by the threat of ambitious environmentalism.

To reduce the interpretation of the causality of all kinds of climate changes and of global warming to one variable, CO2, or to a small proportion of one variable - human-induced CO2 - is impossible to accept. Elementary rationality and my decades-long experience with econometric modelling and statistical testing of scientific hypotheses tell me that it is impossible to make strong conclusions based on mere correlation of two (or more) time series.

People like me who were engaging in brinkmanship with the party economic bosses and the open dissidents who were being arrested were pursuing a common goal in different ways.
