Rather than challenge the honesty of researchers, what would be much more informative, productive, and appropriate (not to mention respectful) would be to focus on the assumptions or shortcomings in the calculations and analyses. In earlier runs with the UKMO model, it took a few thousand years to lead to loss of most of the Greenland ice sheet, quite possibly so long because the model had no representation of ice dynamics, a term that models have generally not yet included and an omission that led to the IPCC AR4 ice loss projections being apparently a good deal less than present observations suggest to be likely if trends continue to accelerate.
As to the quote you give, note that is from the reporter and not the authors, who seem to me to be saying something different than the reporter's sentence and that is obviously true--the more you spend on mitigation, the less you will need to spend on SRM. At least in what is quoted from the authors, they did not seem to say that this would lead to lowest cost overall or least (or acceptable) impacts. So, let's have discussion focus on the physics without innuendo about motives.
