Since then, Horizon have followed scientists as they have tried to unpick how the climate works and whether it is changing. Dr Helen Czerski delves into this unique archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history. It has been a constantly surprising journey of discovery that has revolutionised our understanding of climate, and seen scientists face unprecedented controversy and criticism.

Gripping story-telling illustrated with exquisitely restored and colourised archived films and supported by a global cast of stellar historians bring this crucially important era in history to life.
In the first chapter, Britain and France declare war when Hitler invades Poland. In May 1940 the Germans attack Holland and Belgium as a decoy. As the Wehrmacht comes through the Ardennes and the Luftwaffe strikes in force, French leaders are caught like rabbits in headlights. The Germans are on a drug called Pervitin, which beats off fatigue, and reach the Atlantic coast. There is a danger that the Germans will encircle the Allies and cut them off from the sea. But Hitler issues his Halt Order and some 340,000 Allies are evacuated.

Ramirez shows how experts and art presenters have turned to television to bring Leonardo's artwork out of galleries and into our living rooms. Through television they have explored the origins of Leonardo's boundless curiosity, his pioneering use of light and shade, and his remarkable scientific exploration.
Along the way Dr Ramirez discovers Britain's little-known version of The Last Supper, the gruesome ways Leonardo acquired his anatomical knowledge - and even what lies beneath the Mona Lisa.
