Libya is wildly ambitious and clearly already trying to revolutionise thinking on climate change and science. It plans a monster geoengineering project that would not just cool the Earth by 6C and cut carbon dioxide emissions to zero by 2021, it says, but would reverse global warming, provide power for 2 billion people, lower sea levels and restore the climate of 1750
...Saturday's march of around 20,000 people through the streets of Durban was remarkable for its humour and diversity...I spotted waste pickers, farmers, refugees, indigenous peoples from around Africa and Latin America, unions, people fighting airports, clowns, evictees, landless peasants, NGOs like WWF, Friend of the Earth International and Greenpeace, schools, political parties, students, squatters, slum and shack-dwellers, priests and faith groups, academics, Ogonis from the Niger delta, UN delegates and ambassadors as well as UN climate chief, Christiana Figueres. Best slogans? "Keep the oil in the soil and the coal in the hole" and "Never trust a cop".

Scientists there are now looking towards 1.5C as a safer and more accurate target.

Mark Lynas » COP17: Why the ‘Kyoto or bust’ positions much change

Perhaps the worst outcome of continued Kyoto deadlock is not that the UNFCCC process shatters in a dramatic big bang, but that it continues to slip gradually into irrelevance.
