Andrew Revkin says «The panels» overarching bottom line is straightforward: There is no substitute for dramatic reductions in the emissions of CO2 and other greenhouse gases to mitigate the negative consequences of climate change, and concurrently to reduce ocean acidification.»

If you are silly enough to contemplate a 2 ˚C rise, then just to have a 66 per cent chance of limiting warming at that point, atmospheric carbon needs to be held to 400ppm CO2e and that requires a global reduction in emissions of 80 per cent by 2050 (on 1990 levels) and negative emissions after 2070.

However, most instruments have best practice applications that have achieved CO2 reductions at low or negative social costs, signalling that a broad portfolio of tools is available to governments to cut building ‐ related emissions cost ‐ effectively.

For example, theory and bottom up modelling suggest that some energy efficiency policies can deliver CO2 emission reductions at negative cost, but we need ex ‐ post policy evaluation to establish whether they really do and whether the measures are as effective as predicted by ex ‐ ante assessments.

But the negative consequences of actually exiting, rather than just coming up short on voluntary emissions reduction targets, would be extensive and costly.

For example, one of the scenarios included in the IPCC's latest assessment assumes aggressive emissions reductions designed to limit the global temperature increase to 3.6 °F (2 °C) above pre-industrial levels.3 This path would require rapid emissions reductions (more than 70 % reduction in human - related emissions by 2050, and net negative emissions by 2100 — see the Appendix 3: Climate Science, Supplemental Message 5) sufficient to achieve heat - trapping gas concentrations well below those of any of the scenarios considered by the IPCC in its 2007 assessment.

«Climate science» as it is used by warmists implies adherence to a set of beliefs: (1) Increasing greenhouse gas concentrations will warm the Earth's surface and atmosphere; (2) Human production of CO2 is producing significant increases in CO2 concentration; (3) The rate of rise of temperature in the 20th and 21st centuries is unprecedented compared to the rates of change of temperature in the previous two millennia and this can only be due to rising greenhouse gas concentrations; (4) The climate of the 19th century was ideal and may be taken as a standard to compare against any current climate; (5) global climate models, while still not perfect, are good enough to indicate that continued use of fossil fuels at projected rates in the 21st century will cause the CO2 concentration to rise to a high level by 2100 (possibly 700 to 900 ppm); (6) The global average temperature under this condition will rise more than 3 °C from the late 19th century ideal; (7) The negative impact on humanity of such a rise will be enormous; (8) The only alternative to such a disaster is to immediately and sharply reduce CO2 emissions (reducing emissions in 2050 by 80 % compared to today's rate) and continue further reductions after 2050; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 resulting in significant damage to humanity; (10) Such reductions in CO2 emissions are technically feasible and economically affordable while providing adequate energy to a growing world population that is increasingly industrializing.

Nevertheless, it seems likely that a CO2 concentration in the range 500 to 900 ppm might produce a temperature rise of at least 2 °C from the late 19th century that could be problematic for humankind; (7) The potential negative impact on humanity has been exaggerated; (8) The only alternative to rising greenhouse gas concentrations is to immediately and sharply reduce CO2 emissions — whether this averts a «pending disaster» is not well understood; (9) Even with such draconian CO2 reductions, the CO2 concentration is likely to reach at least 450 to 500 ppm by 2100 probably resulting in some warming; (10) Such reductions in CO2 emissions are neither technically feasible nor economically affordable, and would necessitate inadequate energy supply to a growing world population that is increasingly industrializing, leading to worldwide depression.

The difference between Professor Nordhaus's optimal carbon tax policy and a fifty - year delay policy is insignificant economically or climatologically in view of major uncertainties in (1) future economic growth (including reductions in carbon emissions intensity); (2) the physical science (e.g., the climate sensitivity); (3) future positive and negative environmental impacts (e.g., the economic «damage function»); (4) the evaluation of long - term economic costs and benefits (e.g., the discount rate); and (5) the international political process (e.g., the impact of less than full participation).

But without developing countries getting involved in climate control and R&D investment, such a cooperation alone is unable to completely offset negative economic effects of the emissions reduction commitments on both industrialized countries themselves and developing countries.

The implication: in addition to rapid reductions in CO2 emissions from fossil fuel use, we'll likely need big industrial CCS processes to generate negative emissions via approaches like sustainable bioenergy coupled with CCS and / or direct air capture (DAC) + sequestration to make our climate goals a reality.

In general, once you have an emissions budget, there are three additional choices to make: how to distribute emissions reductions over time, how to allocate the budget between CO2 and non-CO2 greenhouse gases, and whether (and to what degree) «negative emissions» are considered.

This is only legitimate if (a) it is clearly demonstrated (it can't be proved) that any human - caused warming will be net negative, and (b) GHG emissions reductions are the best approach to dealing with this.

Alternative pathways involving lifestyle change, rapid electrification and reduction of non-CO2 gases could reduce the need for such negative emission technologies.
