Thank your for the opportunity for comments. I recommend
California take the lead in adopting scientific parameters for
SLCPs rather than wait on the US EPA. Such action would direct
attention to the 2 substances which would have the most immediate
impact on slowing global warming. Enclosed is a recent
presentation from the Global Methane Forum that was held at
Georgetown University Conference Center. Methane and black carbon
were identified as the two most important substances to reduce to
have an effect in the next 20 years. The next 20 years are more
important than the next 100. Sooner we mitigate climate damage
the less impact we will suffer in outer years. We can still act
to reduce CO2 as a long term strategy but we need to focus on
short term impacts to buy us more time to adapt.
