The Imperial War Museum in London may seem like a strange place to launch a report on climate change. But that's where I am this morning, along with speakers from the Tyndall Centre for Climate Research, the Women's Institute and the museum itself.

Why? Two reasons. First, climate change is one of the greatest threats to our country since the last world war. It's not only environmentalists who are saying this. Business leaders, prime ministers, major charities and generals have all recognised the level of risk.

Second, if we are to overcome this threat – and the alternative is simply too awful to contemplate – then we need to mobilise as a nation in a way we haven't seen since 1945.

The new report – entitled The New Home Front – looks at the wartime experience of those on the "home front" in Britain and the lessons we can learn in facing today's threats from climate change and the looming energy and resources crisis.
