*78 80-90% (As advised by emissions pathways climatologist)(50 to 85% by 2050 on 2000 levels - IPCC called for these CO2 emissions reductions to keep to 2.0-2.4C if peak by 2015 see 1 above.) However 1. Target proposed is 1.5C rather than 2.0-2.4C hence greater emissions reductions necessary 2. Models used to date do not include uncertainties in climate-carbon cycle feedback nor do they include the full effects of changes in ice sheet flow because a basis in published literature is lacking IPCC, 2007: Summary for Policymakers.

Elimination of the shielding effect of aerosols must be taken into account re emissions reductions. (Thus environmental strategies aimed at maintaining global warming below a prescribed threshold must therefore account not only for CO2 emissions but also for measures implemented to improve air quality.)
