climate crisis; • The inclusion
of deforestation, which alone accounts for twenty percent
of the emissions that cause
global warming; • The addition
of sinks including those from soils, principally from farmlands and grazing lands with appropriate methodologies and accounting.

of atmospheric greenhouse gas concentrations at well below below 350 p.p.m., and that to achieve this the agreement at COP15 U.N.F.C.C.C. should include a goal

global emissions by 2015 with a sharp decline thereafter towards a
global reduction
of 85 percent by 2050,
«While the Paris Agreement does not address the issue
of climate engineering expressly, the
target of limiting
global average temperature rise to no more than 2 °C (a goal that appears unlikely to be achieved in the absence

What particularly interested me was the number
of scientists who had been pushed out
of CSIRO, or had left

global warming, and the emissions reductions that would be needed to stabilise the
climate (the latter point is particularly sensitive since any actual number implies a
target and government policy is opposed to
targets).
