I don't mind the government accruing debts as long as every dollar is spent effectively with a high return. That works out fine. If you accumulate debts and waste your money, that's, of course, a disaster.
Libertarians believe that any government interference is bad. Anyone with a brain knows that climate change needs governmental leadership, and they can smell this is bad news for their philosophy. Their ideology is so strongly held that, remarkably, it's overcoming the facts.
