I am not adding words, I am making emphasizes. Sorry if you got the idea that the italics and quotations marks were meant to be quotes.
You are taking her quotes out of context.
They were, for all to read, within a paragraph that was introduced (this time a quote) “Many believe that [...]” and was, exactly as I said, about making the case for non-green energy to a green audience.
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 nation’s energy needs during the transition to green energy alternatives.
In the second setence, starting with the word "However", she is responding to that concern.
