We need to do several things in the US to help ourselves, as well as push other nations.
We would be better off stopping subsidies on solar, and allow wind to expire in 2 years. Instead, we should now focus those subsidies on nuclear power (our own), along with electricity storage.
Then require that all new construction below 5-6 stories will have on-site AE that will equal or exceed its HVAC usage.
In addition, we need to put a tax on all consumed goods (including those shipped from overseas), based on the MAX CO2 that went into make it. The tax should start low and raise every 6-12 months. This will give time to all nations and states to make long-term choices.
Basically, the tax is applied to all goods, unless you register where it and its parts come from. Then if you get the parts from nations/states where the CO2 is lowest, you get lower taxes.
To make sure of the CO2, rather than the wild estimates that we have, we use the OCO2 which will show emissions production, along with movement, around the world.
Finally, to normalize it, we use $ GDP / tonne of CO2. The higher the $GDP, the better.
The above is all that is needed to force us to change, and give us time. Not just America, but all nations since America is the world's largest importer.
