Hansen promotes Climate 'Reparations': 'Developed countries emitted most of the excess carbon that is in the air today, and are thus mainly responsible for human-caused climate change...Reparations are appropriate and needed.'
Hansen: 'The way to phase down fossil emissions rapidly is via a rising carbon fee collected at domestic mines and ports of entry. Each nation can choose how to use the funds, but in most nations the funds had better be distributed to all legal residents. The carbon fee can be made near-global, because border duties would be collected on products from non-participating nations, a huge incentive for all nations to join.'
'Science actually tells us is that we must reduce emissions in the fastest way possible — atmospheric CO2 is already in the dangerous zone.'
'Why march? You will have to answer to your children. You understood the situation at a time when it was not too late. Instead of standing up for them, did you choose to sit at home?'
'Regulations are not a solution, although the threat of them may help bring conservatives to the table.'
Geologist Dr. Don Easterbrook takes apart new draft UN report: "What is really astonishing, is how the discredited IPCC can continue to put out such nonsense totally contrary to real evidence and still pretend to be scientists."
The IPCC’s AR5 attribution statement: 'It is extremely likely that more than half of the observed increase in global average surface temperature from 1951 to 2010 was caused by the anthropogenic increase in greenhouse gas concentrations and other anthropogenic forcings together. The best estimate of the human induced contribution to warming is similar to the observed warming over this period.'
The reasoning process used by the IPCC in assessing confidence in its attribution statement is described by this statement from the AR4: “The approaches used in detection and attribution research described above cannot fully account for all uncertainties, and thus ultimately expert judgement is required to give a calibrated assessment of whether a specific cause is responsible for a given climate change.'
Curry: 'The attribution statement itself is at best imprecise and at worst ambiguous: what does “most” mean – 51% or 99%? Whether it is 51% or 99% would seem to make a rather big difference regarding the policy response.'
'The IPCC’s attribution statement does not seem logically consistent with the uncertainty in climate sensitivity.'
'I am arguing that climate models are not fit for the purpose of detection and attribution of climate change on decadal to multidecadal timescales.'
