Experiencing global warming impacts
In May 2005 I was fortunate to make a visit to the Iguazu Falls on the border between Brasil and Argentina. Even at that time the river was low but the falls were spectacular. Compare the photos taken of the same area then (above) and now (below - source: Aurea Cunha/Gazeta do Povo/AE).

Yet in this country (Oz) the current (and long-term) Federal government are in denial presenting a policy that is perhaps best described as 'environmental terrorism'. In this case I follow the definition of terrorism as 'systematic intimidation as a method of governing or securing political or other ends'. One only has to read the paper by Clive Hamilton (The Dirty Politics of Climate Change) to see how this is enacted. The net effect is to protect vested interests (promote first-order change) at the expense of innovation and change, particularly the emergence of new insitutions and economic activity that will address the systemic basis of climate change at the same time as creating demand pull for new technologies and institutional arrangements (second-order change).
