More than 1,200 California Nurses Association/National Nurses Organizing Committee registered nurses, environmental and healthcare activists, and students on Dec. 3 marched and rallied in Los Angeles to demand that the world’s leaders, now convening in Paris for the United Nations Conference on Climate Change, adopt a binding and enforceable climate treaty, commit resources to fund the transformation to clean, renewable energy including a just transition program for those who now work in the fossil fuel industry, and call on wealthy, developed countries to provide resources for the less-developed countries to act on climate, with funding coming from a carbon tax and the Robin Hood tax.
