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.

My main concern is the political dimension of European integration. This is one of the most important issues of all, as far as I'm concerned. It has to do with our past, with our sensitivity, perhaps even our hypersensitivity in this regard.

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.

I never intended to be a politician or office-seeker.

I also helped write the five-page statement of principles that Civic Forum issued in late November. That was the first public expression of what the new government wanted to do.

The climate change debate is basically not about science; it is about ideology. It is not about global temperature; it is about the concept of human society. It is not about nature or scientific ecology; it is about environmentalism, about one - recently born - dirigistic and collectivistic ideology, which goes against freedom and free markets.

Being often with many leading politicians, I feel frustrated that they do not listen. They already know. They fully subscribed to the idea that talking about 'saving the planet' is an effective way to show their 'caring' for humanity and that it is the easiest way to maximize votes irrespective of any relevant activity which would aim at the real needs of people. The global warming dogma has become a very easy form of escapism from the current reality.
