Is Margaret Thatcher responsible for today’s climate alarmism?

According to Dr. Syun Akasofu of the International Arctic Research Center At The University of Alaska Fairbanks: yes. 

How is global warming related to atomic power? In order to understand this question, it is important to learn how the global warming issue was born. In the 1980s, Margaret Thatcher, then the British Prime Minister, came to the conclusion that the UK needed atomic power energy for their future, but she faced strong objections by her people. It was also about the time when the first crude computer simulation of the greenhouse effect of CO2 was made, and it predicted a great disaster and catastrophe due to the expected temperature rise, unless the release of CO2 could be greatly reduced.

Margaret Thatcher must have taken this result into account in promoting atomic power, asking her people to choose either atomic power or global disaster/catastrophe, which would require a great sacrifice in their standard of living in order to avoid it. Without her strong endorsement, the IPCC would not have been established. She also established the Hadley Climate Research Center for further study of the effects of CO2. Until that time, climatology was a rather quiet science (not something dealt with in newspaper headlines), but Thatcher put a great spotlight on it for her political purposes. Therefore, although the CO2 hypothesis is appropriate as a hypothesis in science, the IPCC was related to atomic power from its birth and its destiny was to predict a great disaster/catastrophe.
