ABSTRACT
Looking at the events thematically, we notice that change is a long-term process, but sustained momentum is important to reach the necessary tipping points in public opinion, policy response and business action. For example, the global warming greenhouse effect was first discovered by Jean-Baptiste Fourier in 1824, but it is only really in the last three years that climate change has become a top agenda item for the news desks, parliaments and boardrooms of the world.
