Hmm, that raises the spectre of thought police, being jailed for your beliefs, all the kinds of things we really don't want to go back to.
As much as I think that people who refuse to accept the science are slightly dotty, I don't think we can blame the effects of climate change on only those who refuse to accept it. How about a climate change denier who nonetheless lives in an inner-city location so doesn't drive, has a flat in an eco-friendly apartment (purely because of the view), and happens to be a vegetarian? Their carbon footprint would be much less than mine, so strictly speaking I should be charged more for damaging the climate even though I accept the science.
There's only one way to really combat climate change - price it. Items wrapped in plastic should be taxed far more than items that aren't. Put a price on carbon. (Julia tried it but that f*wit Abbott wrecked it). Give massive subsidies on electric vehicles and infrastructure until the market catches up. Make all public transport free (and much more of it) and tax fuel til it's $5 a litre. Stop giving a free ride to the airlines which would lift fares to what they should be, which will reduce unnecessary travel. Fix the electricity networks until they can handle the fluctuations of solar and wind, invest in massive battery farms, and then tax fossil fuel generation until it's unsustainable. Put a ban on any new coal mining and make a proper plan to phase out existing.
Would I like all this? No. It would impact me greatly. But if we want to be honest about combating climate change then we all have to feel the pain so our kids and grandkids have a chance at a reasonable life.
