Adam, I think I get the individual changes that reduce one's carbon footprint. If Mervin Mfg skis, snowboards, and surfboards represent a systematic change, you're losing me. Yes, it's environmentally better than big brands made overseas, but the increment is so small that I guess I didn't see it as "systematic." Yes, I have mostly LED lightbulbs, but maybe I don't know enough about the "grid." I'm most familiar with the west coast energy grid as developed by Bonnville Power Administration. There are three, maybe now four, regional interties that fairly efficiently shuffles electric energy between western MT, ID, WA, OR, and CA, and connects hydro, wind, solar, nuclear, and coal. Unlike Texas, which is isolated and ended up killing people in the cold snap there about 4 years ago. I'm trying to see what a systematic change looks like. Is it persuading or forcing Texas to connect to a regional grid utilizing more diverse energy sources?
I'm still having a hard time seeing how multiple "large" systematic changes are going to make a significant impact on climate. I'm not arguing against such changes. I'm being my analytical self. For instance, I read not long ago that if the entire planet converts from ICE vehicles to electric vehicles (EVs), that would contribute only 3% of the effect necessary to bring global climate temperatures to the desired or necessary 1.5*C to curb global warming. Hence why I'm trying to get my mind around what these proffered "large systematic changes" look like. My back of the envelope style calculations are that it's gonna' take even more than completely banning heli and snowmobile skiing - along with similar restrictions of every other modern outdoor pursuit and most commercial pursuits - to make it to that 1.5*C finish line threshold. I guess my question is a "can we get there from here?" sort of question. And if so, how?
