How To Get To Net Zero Carbon Emissions: Cut Short-Lived Superpollutants (thebulletin.org) 184

Dan Drollette writes: We absolutely, positively, must tackle climate change speedily. Or as the authors of this article put it: 'By 'speed,' we mean measures — including regulatory ones — that can begin within two-to-three years, be substantially implemented in five-to-10 years, and produce a climate response within the next decade or two.' (Quick aside: one of the authors, Mario Molina, won the Nobel Prize in chemistry in 1995, for his work on holes in the ozone layer.)
From the article: Rapid warming over the near term threatens to accelerate self-reinforcing feedbacks in which the planet starts to warm itself in a Hothouse Earth scenario — vicious cycles which could lead to uncontrollable warming as these feedback mechanisms become the dominant force regulating the climate system. These feedbacks would then set off a domino-like cascade that triggers tipping points in the Arctic and elsewhere, many of them irreversible and potentially catastrophic.

      • All value is inherently perceived/subjective. If you don't understand that, you certainly don't know enough to be giving advice.

        • Most value is subjective, as "I think this is of value to me." However, some things are objectively valuable because they're necessary to your life, such as food, water, and air. Closely related, some things have objective value because they improve your life, such as sleeping on a bed in a house in comparison to sleeping in a gravel pit. If you live your life well, the subjective category tends to align with the objective category.

    until we do something about the economy. Specifically we need to address how fragile it is. Nobody is going to let you spend one red cent fighting climate change when they're living paycheck to paycheck. They're terrified that anything you do will push them over the edge into homelessness.

    Bernie Sanders had the right idea, which is a massive federal jobs program to address climate change. That hits two birds with one stone, e.g. it makes sure workers have economic stability while fighting climate change.

    Anything else is just pissing into the wind by trashy Neo-liberals.

      Centrally planned economies have such a great track record. I suppose they do limit climate change in that they're so terribly ineffective that don't produce as much. If the types of jobs that Bernie were proposing were viable, the private sector would already be rushing to provide them. But every job that gets created by some make-work federal program is one job that can't be filled elsewhere and no doubt needs to be supported by all of the other productive jobs that people are willing to pay to support without coercion.

      If you really want to fight climate change create economic incentive to do so. Give companies tax breaks for lowering energy use or for any inventions which result in less pollution or fewer emissions. Implement a market-based system for pollutants so that inefficient industries and processes are replaced faster, just like we did with sulfur dioxide to reduce acid rain.

      I think it really says something about how bad Bernie's policies are when the Democrats would rather get behind someone with dementia or some other form of severe cognitive decline. I'll gladly take the trashy neo-liberals pissing into the wind over the Marxists huffing their own farts.

Do you have any bloody idea how much work it's going to take in order to get America off fossil fuels as our primary source of energy and onto renewables? It's not just building out wind and solar + batteries. We've got to transform our buildings to be more energy efficient. Same for our cars. And we're gonna screw it up because it's complicated.

          Oh bullshit they cheated. Bernie lost to Hillary in 2016 and he's losing to Biden in 2020. He's actually polling worse against Biden than he did against Hillary, which really shouldn't be unexpected at all. In head-to-head polls against Trump, Bernie ties him, while Biden clearly wins. There's no cheating. Bernie just isn't as popular as his supporters think he is.

      The planet was in balance before humankind started polluting the atmosphere with greenhouse gases coming from fossil fuels. So we have to get back to this stage rapidly, if we want to survive. A carbon tax of $650 per ton CO2 would cover for the costs of the pollution and would be a first step. Whoever polluts has to pay for the damage it does, and not the taxpayer in general. Subsidies have to stop.

          But my point was that we already know that CO2 from volcanism affects climate, and we produce way more.
