In 2003, her book Statecraft recanted her earlier views, casting doubt on "alarmist" science of the Intergovernmental Panel on Climate Change (IPCC) - a body she helped to create - and warning that: "The new dogma about climate change has swept through the left-of-centre governing classes."
She said the international effort to tackle climate change "provides a marvellous excuse for worldwide, supra-national socialism".
Was Margaret Thatcher the first climate sceptic?

In bringing this about, Mrs Thatcher played an important part. It is not widely appreciated, however, that there was a dramatic twist to her story. In 2003, towards the end of her last book, Statecraft, in a passage headed "Hot Air and Global Warming",
she issued what amounts to an almost complete recantation of her earlier views.
She voiced precisely the fundamental doubts about the warming scare that have since become familiar to us. Pouring scorn on the "doomsters", she questioned the main scientific assumptions used to drive the scare, from the conviction that the chief force shaping world climate is CO2, rather than natural factors such as solar activity, to exaggerated claims about rising sea levels. She mocked Al Gore and the futility of "costly and economically damaging" schemes to reduce CO2 emissions. She cited the 2.5C rise in temperatures during the Medieval Warm Period as having had almost entirely beneficial effects. She pointed out that the dangers of a world getting colder are far worse than those of a CO2-enriched world growing warmer. She recognised how distortions of the science had been used to mask an anti-capitalist, Left-wing political agenda which posed a serious threat to the progress and prosperity of mankind.
In other words, long before it became fashionable, Lady Thatcher was converted to the view of those who, on both scientific and political grounds, are profoundly sceptical of the climate change ideology. Alas, what she set in train earlier continues to exercise its baleful influence to this day.
But the
fact that she became one of the first and most prominent of "climate sceptics" has been almost entirely buried from view.
