the severity of ongoing alterations of terrestrial and 
marine environments, with potentially catastrophic 
results. Ongoing and projected effects include more 
prevalent droughts in dry regions, an increase in the 
spread of disease, a significant reduction in water 
storage in winter snowpack in mountainous regions 
with direct and important economic consequences, a 
precipitous rise in sea levels by the end of the cen-
tury, the potential devastation of coastal commu-
nities, severe and irreversible changes to natural eco-
systems such as the bleaching and destruction of 
much of the world’s coral, and the potential extinc-
tion of 30 percent of all living species. 
(3) That these climate change effects and risks 
of future effects are widely shared does not minimize 
the adverse affects individual persons have suffered, 
will suffer, and are at risk of suffering because of 
global warming. 
(4) That some of the adverse and potentially 
catastrophic effects of global warming are presently 
at risk of occurring and not a certainty does not ne-
gate the harm persons suffer from actions that in-
crease the likelihood, extent, and severity of such fu-
ture impacts.

(5) To preserve the ability to stabilize atmos-
pheric greenhouse gas concentrations at levels likely 
to protect against a temperature rise above 2 °C 
(3.6 °F) and maintain the likelihood of avoiding cat-
astrophic global warming will require reductions of 
greenhouse gas emissions of 50 percent to 85 per-
cent globally. 
(6) Achieving such reductions will require a 
multitude of actions across the global economy that 
may each address a relatively minute quantity of 
emissions, but will be cumulatively significant. 
(7) With only 5 percent of the world population, 
the United States emits approximately 20 percent of 
the world’s total greenhouse gas emissions, and must 
be a leader in addressing global warming. 
(8) The United States Government is the larg-
est energy consumer in the United States and is re-
sponsible for roughly 100,000,000 metric tons of 
CO2-equivalent emissions annually. 
(9) A reduction in greenhouse gas emissions by 
Federal agencies would slow the increase of global 
emissions, thereby slowing the increase of global 
warming and the exacerbation of the risks associated 
with global warming. In addition, Federal action 
would accelerate the pace of development and adop-
