The choice is between leaving CO2 emissions to the markets with every expectation of large and rapid decreases in CO2 emissions or pursuing a government regulatory and subsidy approach that is unlikely to achieve anything except a bitter political and legal fight, rapidly increasing electricity rates, and rapidly declining electricity reliability.

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.

A few other problems: - While there is an extremely good correlation between accumulated emissions and accumulation in the atmosphere, the correlation is less when one looks at the year by year increase, simply because temperature changes have a short term influence (about 4 ppmv/degr.C) on the increase rate, not on the trend!

In scientific literature a few comparisons between the SRES projections and reality exist, like a 2007 PNAS study, which stated «The emissions growth rate since 2000 was greater than for the most fossil - fuel intensive of the Intergovernmental Panel on Climate Change emissions scenarios developed in the late 1990s.&raquIn scientific literature a few comparisons between the SRES projections and reality exist, like a 2007 PNAS study, which stated «The emissions growth rate since 2000 was greater than for the most fossil - fuel intensive of the Intergovernmental Panel on Climate Change emissions scenarios developed in the late 1990s.&raquin the late 1990s.»

(2007) reporting on the recent lack of any detectable acceleration in the rate of sea - level rise.

In all of the emission pathways considered, emissions peaked between 2010 and 2050 by construction, and thus cumulative emissions between 2010 and 2050 are reasonably well correlated to peak emissions rate, particularly when we only consider pathways with rates of emissions decline between 0 and 4 per cent.

The United Nations» Intergovernmental Panel on Climate Change, a global effort involving hundreds of climate scientists and the governments of 100 nations, projected in 2001 that, depending on the rate of greenhouse gas emissions and general climate sensitivities, the global average temperature would rise 2.5 to 10.4 degrees Fahrenheit between 1990 and 2100.

To summarize: available evidence indicates that the differences between projected emissions using MER exchange rates and PPP exchange rates are small in comparison to the uncertainties represented by the range of scenarios and the likely impacts of other parameters and assumptions made in developing scenarios, for example, technological change.

with its highly optimistic assumptions about the future availability of renewables, nuclear, and CCS, the mid-century carbon emission reduction goal could only be achieved if the annual growth in GDP per capita between now and 2050 were to slow to a rate of 1 % per year.

The actual amount of emissions reductions that are needed between now and 2020 is somewhat of a moving target depending on the level of uncertainty that society is willing to accept that a dangerous warming limit will be exceeded, the most recent increases in ghg emissions rates, and assumptions about when global ghg emissions peak before beginning rapid reduction rates.

However, there remains uncertainty in the rate of sea ice loss, with the models that most accurately project historical sea ice trends currently suggesting nearly ice - free conditions sometime between 2021 and 2043 (median 2035).12 Uncertainty across all models stems from a combination of large differences in projections among different climate models, natural climate variability, and uncertainty about future rates of fossil fuel emissions.

The reason for a reduced CO2 rate of rise was probably not due to a reduction in emission rates, but it may have reflected carbon cycle feedbacks that slightly altered the balance between atmospheric CO2 and terrestrial and oceanic sinks.

The paper finds that just 1.2 percent overall methane emissions are attributable to the U.S. natural gas industry, based on the most recent EPA methane emission estimate of 1.2 percent of production, which is in line with a number of studies that find low U.S. leakage rates between 1 and 1.8 percent.
