Fiat debt slavery is designed to and does drive excessive inflation and of course debt. Part of the answer to climate change is a monetary system that encourages saving and thrift (which BTC does!) and encourages more capital direction by the holders of accumulated liquid capital (which is Bitcoin!). The fiat debt slavery bankers cartel has enslaved not just citizens but governments. They own most governments and prevent the meaningful response that is required to the real challenge that is our current culture of debt fueled over consumption. IMO, Do NOT try to argue against the climate change issue itself- instead emphasize that Bitcoin by empowering people and encouraging saving and thrift is a major way of combating climate change. Personally I believe climate change is real- there can be argument about the edges but the core science is established- trying to debate that will send you and the Bitcoin narrative you raise toward the loony bin. Bitcoin is about a major change in the monetary system- from one controlled and manipulated by bankers and politicians to one that treats all people equally without fear or favour- Bitcoin would modify peoples attitude toward spending and saving empowering them to live more sustainable less debt driven consumption centred lives.
