However, a clear understanding of how national emissions reductions commitments affect global climate change impacts requires an understanding of complex relationships between atmospheric ghg concentrations, likely global temperature changes in response to ghg atmospheric concentrations, rates of ghg emissions reductions over time and all of this requires making assumptions about how much CO2 from emissions will remain in the atmosphere, how sensitive the global climate change is to atmospheric ghg concentrations, and when the international community begins to get on a serious emissions reduction pathway guided by equity considerations.

The Lieberman - Warner American Climate InSecurity Act (A-CISA) has, as its core centerpiece, a poorly structured Cap and Trade program, inadequate for achieiving required reductions in US (and Global) GreenHouse Gase (GHG) emissions while giving away $ 500 billion (and likely more) to serial polluters, making the task of reducing America's fossil - fuel addiction that much more costly -LSB-...]

Although different theories of distributive justice would reach different conclusions about what «fairness» requires quantitatively, most of the positions taken by opponents of climate change policies fail to pass minimum ethical scrutiny given the huge differences in emissions levels between high and low emitting nations and the enormity of global emissions reductions needed to prevent catastrophic climate change.

For instance the following illustration prepared by EcoEquity and the Stockholm Environment Institute shows that the US fair share of global emissions, making what the authors of the report claim are moderate assumptions of what equity requires, demonstrates that equity not only requires the US to reduce its emissions to zero quickly almost immediately but that US obligations to prevent a 2 degree C rise requires the US to substantially fund ghg emissions reductions in other countries by 2025 despite achieving zero emissions by 2020.

(Brown, 2009) Because each nation or government has a duty to reduce its emissions to its fair share of safe global emissions (Brown et al, 2006), justice requires that caps be consistent with the government's ghg reduction obligations.

Although different theories of distributive justice would reach different conclusions about what «fairness» requires quantitatively, most of the positions taken by opponents of climate change policies fail to pass minimum ethical scrutiny given the huge differences in emissions levels between high and low emitting nations and individuals and the enormity of global emissions reductions needed to prevent catastrophic climate change.

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.

Although there are many countries other than the United States that have frequently failed to respond to what justice would require of them to reduce the threat of climate change, the United States, perhaps more than any other country, has gained a reputation in the international community for its consistent unwillingness to commit to serious greenhouse gas emissions reductions during the over two decades that world has been seeking a global agreement on how to respond to climate change.

This latest report was made at the conclusion of these negotiations during which almost no progress was made in defining equity under UNFCCC by the Ad Hoc Working Group on Durban Platform For Enhanced Action (ADP), a mechanism under the UNFCCC that seeks to achieve a adequate global climate agreement, despite a growing consensus among most observers of the UNFCCC negotiations that nations need to align their emissions reductions commitments to levels required of them by equity and justice if the world is going to prevent extremely dangerous climate change.

South Afrrica, despite being a non-Annex 1 country, has acknowledged its status as the highest ghg emitter on the African continent and announced a voluntary emissions reduction target, the objective of which is to make a «fair contribution'to keep global concentrations within the range required to keep within the 2 degree C warming limit.
