My realizations over the years:
Even if we make our cars less carbon-polluting by 25%, if we end up driving more, we could still end up polluting more.
Even if the western nations pollute less, developing nations will still pollute a lot more and will get us to tipping points anyway, albeit perhaps slightly slower.
Global warming effects are scary, but what's worse is global cooling and Ice Age. Once the ocean's balance is messed up by diluted salinity due to melted ice caps, who knows where this can go.
Look, a nation looking to expand its territory due to oil. Where's all the anti American Lemmy users to say how imperialistic they are?
