A few notes[edit source]
No time now, but this could be worth following up. From an email sent to Crikey.com.au:
- US NASA scientist Jim Hansen ... what Jim Hansen actually thinks is well expressed in an email he sent to US colleagues on 27 February in which he writes: "What can be called ... 'fast feedback' climate sensitivity is now well-established ... We will begin to notice these additional feedbacks now, as we have entered the period of significant almost-monotonic global warming with isotherms moving poleward ... We do not know what long-term level of CO2 constitutes 'dangerous human-made interference' ... but it has become clear that it is not greater than about 450 ppm, and may be considerably lower ... the US will continue to be primarily responsible for the human-caused climate change for many decades into the future. So, unless we begin to act responsibly, we will leave a tremendous moral burden, and perhaps a legal burden, for our children and grandchildren (and ourselves: some effects are going to be obvious soon enough)... The greatest obstacle to solving the climate crisis is the 'special interests'."
