Check out Gwynne Dyer’s CBC podcast Climate Wars. There are three parts and the first, posted here, is the most gripping. Roll over and hit play in the Snapshot, or 2click to download.
Highlights
15:55: Uncertainty about climate change does not refer to whether it is happening but how fast.
21:50: So, how did climate change become ideological? People don’t take up ideological positions on the cause of earthquakes, for example, so, why on climate science? Dyer argues that the division of climate change into right/left is an American phenomenon. Dyer provides very interesting evidence that climate change in America became a cultural conflict about values: values, and not evidence determine acceptable responses to climate change.
32:00: The significance of feedback effects, for example, the methane stored and released by melting permafrost.
37:15: To the extent that climate change is a result of human activities, 2C is a tipping point for feedback effects at which point we are likely to lose control over our ability to control greenhouse gases. In other words, human efforts to reduce emissions will have no effect.
42:15: The possibility of international cooperation is hampered by nationalism and patriotism: see interviews with Russian politicians responsible for planting the Russian flag at the bottom of the Arctic.
49:50: Civilizations always grow populations up to carrying capacity for food, and have never been able to restrict growth so as to sustain themselves. We are just another example.
