Dr James Hansen.

Jim Hansen has been researching climate science through Paleontology (ice core samples) since 1988. He heads NASA and is regarded as the leading climate scientist in the world. Not only has he authored many scientific papers and books, he has also taking off his white coat for the principals he advocates, and being arrested – most recently at the anti TAR SANDS Washington rally.

This panel discussion with associates explores climate “sensitivity”, or “at what speed the climate reacts to FORCINGS”. The “FORCINGS” in discussion are the 800 metric tonnes of CO2 -e PER SECOND that “civilization” pumps into the atmosphere.          70,000,000 ( seventy million ) tonnes  a day.                                              25,500,000,000 (25 billion metric tonnes per year)

An “unprecedented” amount of the same stuff that has caused ALL OTHER “NATURAL” ice ages and “interglacial” periods where sea levels are up to 100 metres HIGHER.

Dr Hansen REITERATES that a “safe climate” MUST be regarded as one with CO2 content of 350ppm. To reduce emissions to achieve that target, beginning in 2015, requires a reduction in emissions of 5% per annum. If it is left UNTIL 2020 (AS SOME SIGNATORIES TO THE “DURBAN PLATFORM” (i.e. USA) SUGGEST, the reduction in emissions to achieve 350ppm is 15% p.a. This requires the decarbonisation of the power generation sector – when France introduced nuclear power in the 70’s-80’s, their reduction in emissions was 4% per annum.
