No I am not. As I said before, (I believe) it was to respond to those "who believe".
You are adding a context that doesn't exist.
Many believe that in order to mitigate these long term and systematic changes it will require a national and global effort to decrease the release of human produced greenhouse gases into the atmosphere. However, simply waiting for low carbon emitting renewable capacity to be large enough will mean that it will be too late to meet the mitigation goals for reducing CO2 that will be required under most credible climate change models, including the International Panel on Climate Change (IPCC) modeled scenarios. Meeting these goals will require a dramatic increase, in the very near term, to preferred available fuels - including natural gas that have a very low carbon footprint and that can be used within the existing energy infrastructure. These available fuels are required to supply the nations energy needs during the transition to green energy alternatives.
In the second setence, starting with the word "However", she is responding to that concern.
This is your interpretation. I think you are reading something into it, as you accuse me to do.
In my opinion it is plain apparent that as I said repeatedly before, she is making the case that those who believe in man made global warming should be supportive of non-green energy, instead of waiting for green alternatives.
