The climate is a foundational issue. Beto O’Rourke deserves praise for putting a policy out there. Jay Inslee deserves credit for making it the central issue of his campaign.
The basic problem isn’t hard to understand. We burn carbon fuels, and that releases CO₂. The carbon accumulates in the atmosphere, warming the planet. It accumulates in the oceans, making them more acidic. We have to burn less carbon.
Given we still want to have stuff from far away, and that transportation is one of the largest sources of pollution, transportation is a big target to change. Electrification of transport, coupled with renewable generation of electricity, is the logical step toward carbon neutrality.
But we also know that humans are stubborn, particularly wealthy humans that make a lot of money selling carbon. Economists recognized that getting them to go along is difficult because they can simply lie about the science, buy politicians (or even the whole Republican Party), and stall any real change. So, economists propose a variety of pricing systems, whereby carbon emissions are priced.
Think of it like a gold rush. Someone shouts, “There’s gold in them-thar hills,” everyone goes for it. Already there’s some gold in decarbonizing, but there’s less than there would be if the actual costs of carbon were recognized as part of the economy. By adopting some form of carbon pricing, the greed of man is leveraged to turn gas guzzlers into sippers or even into electrics or hydrogen fuelcells.
Think of it like a tower-building contest. Right now, the contestants are paid per foot, so if you have a tower that’s barely over one foot-mark, it would take more effort to get to the next one. By pricing carbon, it’s like changing it to being paid by the inch. If you can add six inches, it doesn’t make another foot, but it’s still worth it. And you add up all the six-inch additions that all the tower-builders can add, and it’s a lot more than if just a few of them could add a whole foot.
But the main thing is focus. We need leaders, both in the White House and in the congress, who will speak often about the need to address the issue. It’s time for legislation. It’s time to reject anyone who calls it a Chinese hoax.
The consensus is to make carbon more expensive, and in doing so to make alternatives, including reductions in use, clean energy, and carbon sequestration more attractive.
