As a Fellow of the Royal Society, Britain's national science academy, she presented a series of high profile speeches on the topic of climate change. Armed with a degree in chemistry from Oxford, her scientific expertise enabled her to speak from a position of strength and knowledge about climate-related issues.
She used that knowledge to act as a champion for the Intergovernmental Panel on Climate Change, and personally opened the Hadley Centre for Climate Prediction and Research (the UK's foremost climate change research centre).
What many people admired about Margaret Thatcher was her ability to embrace the potential of science to guide and lead the way on environmental issues. What marked her out even more is that she embraced the 'precautionary principle' years before other politicians did. As she once said:
"...the danger of global warming is as yet unseen but real enough for us to make changes and sacrifices, so that we do not live at the expense of future generations."
On November 8th 1989, she addressed the General Assembly of the United Nations about the need for nations to join together in tackling climate change.
It was a groundbreaking speech where she eloquently set out the case for international action and argued for an ongoing role for the IPCC. Indeed, some would argue that the IPCC owes its existence to the support that Thatcher gave it at that time.
Her political understanding of the issue also led to her call for a global response that would bring about real change:
"It is no good squabbling over who is responsible or who should pay. Whole areas of our planet could be subject to drought and starvation if the pattern of rains and monsoons were to change as a result of the destruction of forests and the accumulation of greenhouse gases. The environmental challenge which confronts the whole world demands an equivalent response from the whole world. Every country will be affected and no one can opt out."
Twenty-three years after that speech, the world is still lacking a political leader with Thatcher's scientific understanding and the will to tackle the climate issue head on. This was a problem that she herself foresaw. In her speech to the second World Climate Conference in 1990 she said:
"Our ability to come together to stop or limit damage to the world's environment will be perhaps the greatest test of how far we can act as a world community. No one should under-estimate the imagination that will be required, nor the scientific effort, nor the unprecedented co-operation we shall have to show. We shall need statesmanship of a rare order."
Whether you agreed or not with her political outlook, Margaret Thatcher's speeches on climate change have a timeless resonance and strength that are as powerful today as they were 23 years ago.
As she herself said:"We must remember our duty to nature before it is too late. That duty is constant. It is never completed. It lives on as we breathe. It endures as we eat and sleep, work and rest, as we are born and as we pass away."
