Tbh, I don't see bitcoin being the greater of all the evils contributing to climate change. There are still factories burning a lot of fossil fuels and automotive using the same type of fuel for the past decades or so. All of these carbon emissions are already there together with the talks about climate change way before bitcoin hit the radar of so-called 'concerned' citizens. If I were to ask, there's really not much we can do about the power consumption of the miners and we're not the only industry to use such levels of power consumption in the world.
Switching to PoS is not a bright move, and if we really want to save this world, look for better and cleaner alternative energy solutions and ditch the fossil fuels.
I have to second this. Bitcoin mining takes up a lot of power consumption, however, I doubt it is contributing greatly in climate change. For one, there are not much bitcoin miners compared to factories burning fossil fuels that have been in operation for far longer than bitcoin miners. To be honest, I do not understand why people keep associating bitcoin mining with climate change getting worse. If we look closely into the effects of climate change, there are much more things we can put our blame on. Mining bitcoin should not be on top of the list.
