This Portsmouth Herald story describes NH’s contribution to this push by the group Clean the Air. The whole thing is a little vague on details - "reducing global warming pollution in the next 10 years,ensuring reductions of 60 percent to 80 percent by 2050" leaves a lot of wigle room - but it’s nice and clear on the sense of urgency needed: "We must begin to significantly reduce ouremissions within 10 years if we are to limit global warming to 3.6° Fahrenheitand avoid the most dangerous impacts of global warming. The window ofopportunity is closing, and the time for action is now."
