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.

What is concisely referred to as global warming, is a fatal mistake of the present time.

Then in 1969, I spent the spring term at Cornell University in New York. The invasion of August 1968 had already happened, but the hardline regime took several months to crack down on dissidents.

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.

I was paid to read Western economic texts. In a way, the regime paid for their own undermining.

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.

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.
