The Fifth Report of the Intergovernmental Panel on Climate Change released today re-emphasizes the conclusions expressed in previous IPCC Reports. What is new is a focus on risk. The Fifth Report sets out the impacts of climate change in considerable detail, with a careful statement of the probability of their occurrence.
Popular opinion may regard risk consequent on climate change differently from country to country. People in Northern Temperate Climate Countries may think that global warming can’t be all that bad. Particularly when they have come through a long, cold winter in which the snowfall compares with winters they experienced as children, oh so long ago – even before the term “climate change” had worked its way into a publicly consciousness. (Does that sound like Canada?)
