This paper is odd:

An old friend taught me to ignore text and focus on equations instead.nature.com/articles/s4158… The authors note that some previously published papers estimated Equation (4) and others estimated Equation (8) or the equivalent Equation (9).

They then argue in favour of (9) over (4). I agree.

A long while ago, a young epidemiologist decided to code his own statistics software, ignoring the professionals. The app was popular. When a coding error was discovered, 20 years of research on the impact of pollution on health was thrown in the bin. The errors in the climate change attribution literature are of the same scale, decades of research that is simply wrong.

The problem here is not a coding error, but a design flaw. The cause is the same: A failure to consult professional statisticians.

30 years after the first carbon tax was imposed, the literature on the ex-post evaluation of climate policy is still remarkably thin

Direct regulation is the government telling people and companies what (not) to do, and how (not) to do it. #climateeconomics Direct regulation works fine if there are few, similar sources of emissions. It does not work for greenhouse gases. #climateeconomics

Emission reduction costs money as it forces companies and households to use more expensive energy and dearer technology. #climateeconomics The economy can be fully decarbonized at negligible cost if policy design is smart and abatement is gradual. #climateeconomics

Fossil fuel combustion is the main source of CO2. Per unit of energy, coal emits most, followed by oil and gas. #climateeconomics Land use change and cement production are other sources of CO2. Specialized industries emit halocarbons. #climateeconomics

In the IIASA database, there are 718 estimates of how much CO2 emission reduction, in 2020, would result from a carbon tax. The two extremes are a 99% emission reduction for a $44/tCO2 tax and a 36% emission reduction for a $2129/tCO2 tax.

Article 2 of the UN Framework Convention on Climate Change calls for stabilization of the atmospheric concentration of CO2. #climateeconomics Part of CO2 emissions stay in the atmosphere forever -- or rather, is removed at the rate at which rocks grow. #climateeconomics

People adapt to climate change, reducing the negative impacts and increasing the positive impacts. #climateeconomics Adaptation reduces the need to mitigate climate change, and mitigation reduces the need to adapt. #climateeconomics
