Sami writes that " there was a time when Thatcher was seen as a champion of climate science - shocking the UN in the 1980s with a call to to action on man-made global warming." In 1990 she said in a speech, quoted by David Frum:
The IPCC tells us that, on present trends, the earth will warm up faster than at any time since the last ice age....Many of the precautionary actions that we need to take would be sensible in any event. It is sensible to improve energy efficiency and use energy prudently; it's sensible to develop alternative and sustainable and sensible ... it's sensible to improve energy efficiency and to develop alternative and sustainable sources of supply; it's sensible to replant the forests which we consume; it's sensible to re-examine industrial processes; it's sensible to tackle the problem of waste.
I really like her phrase putting it in terms of real estate, english style:
No generation has a freehold on this earth. All we have is a life tenancy with a full repairing lease.
Then it all went wrong. In later years she became a key voice for climate skepticism. The left vilified her and wear T-shirts promising to dance on her grave. But she probably never said the most famous quote that transit activists complain about:
A man who, beyond the age of 26, finds himself on a bus can count himself as a failure.
