James Cameron says its cheaper to address climate now

Speaking at the AREDAY conference in Aspen, Colo., this past weekend, Avatar filmmaker James Cameron addressed a key point on many minds, that with the current vacuum of national leadership, the U.S. appears in danger of slipping behind in the race to a clean energy economy
More importantly, Cameron said we have “just a few years” to begin an aggressive program to mitigate climate change or we risk paying a high price, economically and ecologically, he said, invoking what should be a motivator for everyone: our children’s future.
