It is now widely recognised that global warming poses an existential threat to the world as serious as nuclear war. And yet, despite the urgency, despite UN engagement, governments have not stepped up to the plate. The world desperately needs a deeply committed leadership and programme of action to deal with climate change. The global public's growing presentiment of the horrific impact of global warming has enormous potential to shift it into "emergency mode." In this context, pointing to America's WWII mobilisation to battle the Fascist threat, Unprecedented Climate Mobilization urges and informs a full WWII-style climate mobilisation, suggesting ways in which the United States can exercise leadership. This book shows how the American people have historically risen and adapted to "long emergencies", demonstrated in particular by President Roosevelt's ability to mobilise Americans a full two years before the United States declared war on Japan and Germany in December, 1941. Then, as an example of what is possible, US automakers became a cornerstone of the war effort; having built three million cars in 1941 they quickly converted their factories to making tanks and airplanes, producing only 139 passenger vehicles until the war ended in 1945. Today, a similar sweeping conversion of America's outdated energy system to clean energy could take place, if the political will were there. Unprecedented Climate Mobilization offers a comprehensive guide to citizens and governments on the scope of that engagement and how to generate that will. As in the WWII effort, it advocates that all sectors of society be engaged: media, business, labour, religious groups, government - national, state and local, and the public at large. This handbook suggests constructive leadership strategies for every sector of civil society, along with networking opportunities and information resources to help build the climate effort. This handbook also surveys the lost arts of civil disobedience and nonviolent action to assemble the effective tools that civil society will need - the kinds of tools that won civil rights, brought an end to the Vietnam War, served in anti-nuclear campaigns- and that have been updated by more recent movements such as Occupy. Not least, it suggests ways in which activists can maximize personal influence by using Twitter, Facebook and other social media- tools now so powerful that governments and news agencies monitor and carefully analyse their posts and tweet streams. No environmental advocacy group should be without this effective guide to climate action.
