emissions to the extent that the Progressive Left believes is

reductions, as the primary enforcement tool for constraining America's GHG
emissions.
Requires the President, if the NAS report finds that
emission reduction targets are not on schedule or that global actions will not maintain safe global average surface temperature and atmospheric GHG concentration thresholds, to submit a plan by July 1, 2015, to Congress identifying domestic and international actions that will
achieve necessary additional GHG
reductions.

achieve the
necessary domestic greenhouse gas
emissions reductions, or that global actions will not maintain safe global average surface temperature and atmospheric greenhouse gas concentration thresholds, the President shall, not later than July 1, 2015, and every 4 years thereafter, submit to Congress a plan identifying domestic and international actions that will
achieve necessary additional greenhouse gas
reductions, including any recommendations for legislative action.
It could be argued that a society capable of
achieving the kind of rates of
emission reduction in the year 2100 that are assumed under these pathways would almost certainly be able to convert a static
emissions floor into a decaying one if it were
necessary to do so.

Though scientific consensus must always be open to responsible skepticism given: (a) the strength of the consensus on this topic, (b) the enormity of the harms predicted by the consensus view, (c) an approximately 30 year delay in taking action that has transpired since a serious climate change debate began in the United States in the early 1980s, (d) a delay that has made the problem worse while making it more difficult to
achieve ghg
emissions reductions necessary to prevent dangerous climate change because of the steepness of
reductions now needed, no politician can ethically justify his or her refusal to support action on climate change based upon a personal opinion that is not supported by strong scientific evidence that has been reviewed by scientific organizations with a wide breadth of interdisciplinary scientific expertise.
As we have seen above, the commitments made according to the Copenhagen Accord and Cancun agreements that have been ratified by the Cancun agreements leave at the very minimum a 5Gt gap between
emissions levels that will be
achieved if there is full compliance with the voluntary
emissions reductions and what is
necessary to prevent 2 °C rise, a warming amount that most scientists believe could cause very dangerous climate change.
In fact, despite the almost universal acceptance by nations of the 2 °C warming limit, the actual ghg
emission targets and timetables chosen by almost all nations do not meet the levels of
emissions reductions specified by IPCC as
necessary to keep atmospheric concentrations below 450 ppm and thereby
achieve the 2 °C warming limit.
The reasons are several and include: (a) Their
emissions levels are very high compared to others; (b) Huge
