Spending on damage clean up of extreme weather events is becoming hard to assess. If it wasn't insured, it might not be measured. Insurance premiums are rising, and the incomes of people that might need it are falling. It depends on who does the measuring and what does get measured. Damage to subsistence livelihoods in third world nations won't be measured in the same way. Global Carbon Debt is a future related concept. It is hard to price medium term extreme consequences of Ocean warming and acidity, such as reduction of Oxygen production by phyto-plankton, or ongoing global mass extinction, or unlivable climates in global mid-latitude regions such as Australia. These are the carbon debts we will be made to pay later, with severe consequences, if not with money. Bankruptcy is not the only price.
If global carbon debt is priced at $6 trillion dollars extra each year, and CO2 emissions are roughly 40 billion tonnes a year, then the current carbon "price" equivalent is $150.00 per tonne. Existing carbon price schemes have been aggregated by OECD and amount to no more than 14 euros per tonne. Big emitting countries tend to have zero effective carbon price.
It is obvious that the wealth ownership schemes of the Transnational Capitalist Class are not interested in a meaningful price for carbon emissions from all economic activity. It is obvious that most global economic activities would never be able to pay a full carbon price. The conclusion should be that global carbon emissions need to be rapidly reduced, because they cost more than we could ever possibly afford. Present and future carbon damage is "practically unfixable". Especially when the value of money is still strongly related to the price of fossil fuel energy.
Real markets are a mess of failure. Markets involve consequences of modern technologies with many "side-effects", and many of them are delayed. A small carbon tax is effective on funding transition alternatives if used wisely, with conscious choice. Market failures don't fix themselves just by adding a tax, but at least paying some small part of the price of carbon now, indicates a willingness to understand the long term costs of a choice, and make better choices.
