Commonly 2°C has been seen as the threshold for dangerous climate change, although last year the IPCC report on 1.5°C revealed that at that lower level we enter a zone where tipping points may take us to 4°C and beyond.
In a landmark public health finding, a new study from the Harvard School of Public Health finds that carbon dioxide (CO2) has a direct and negative impact on human cognition and decision-making. These impacts have been observed at CO2 levels that most Americans — and their children — are routinely exposed to today inside classrooms, offices, homes, planes, and cars.
Saudi Arabia has complained that Cancún was lousy with NGO representatives and hence they had to waste time talking to them. The Saudis, of course, aim to see that Cancún does not result in any diminution of the use of oil.
The place is also lousy with representatives of fossil fuel and forestry industries, who aim to make a buck out of the whole thing.
Giles Parkinson’s latest report tells of wholesale rorting at Cancún in how emissions and carbon credits are counted.
The UN Environment Program issued a detailed report last week that said accounting rorts from “hot air” from eastern Europe and land use rules could add up to more than two billion tonnes by 2020. The EU has complained they could undermine the entirety of their emission reductions since 1990.
A study by Simon Terry, the executive director of the New Zealand Sustainability Council, goes further. Terry says that by adding in aviation and shipping – which are not accounted for under the Copenhagen Accord – the pledges may turn out to produce an increase in global emissions of 3 per cent from 1990 levels, rather than an advertised fall of up to 18 per cent.
The UN has been concerned that the Copenhagen Accord commitments will yield an “emissions gap” against what is needed to remain within a 2C temperature rise. This gaps means we could be headed for 3-4C instead of 2C. Factor in the latest games being played and we are heading for 6-7C. That is ‘end of civilisation as we know it’ territory.
