What kind of voter really makes climate change an issue above taxes, the economy, or health care?
I try not to be cynical on this issue, but I don't think that any American policy to tackle climate change would really have an impact on the overall meteorological conditions in the world, because there are so many other countries that would probably keep using fossil fuels at the current rate. If anything, China and India might start burning even more fuel in the future as their economies increase.
Most other world leaders - the Chinese government and probable Indian right-wing PM Modi included - at least recognise that climate change is occurring, and are investing in subsidies in renewable energies and carbon capture from coal.
And surely the US, if it wants to preserve its status as a superpower, should welcome spearheading a global attempt to limit carbon emissions. After all, the US has much greater carbon emissions
per capita than any of the BRICS.
Developing countries aren't ignoring climate change - in fact given their precarious position, they can't afford to. If the US elects a climate change denier, it'll just embarrass itself.
