prior 1990, i.e. when global warming was universally recognized), the components of climate debt (see above sections), the difficulties in deciding when to start counting past emissions and if this debate is slowing the implementation of programs or the legal and political consecration of the debt through treaties. Present key debates focus on how is the debt going to be paid back. First, some academia have pushed for financial debt cancellation rather than being paid for ecological damages and then paying back the country's national financial debt. However, financial debts were not even agree by people (in developing countries especially) in the first place, calling it the unfair "Volcker debt". Accepting this option could hold the risk of giving legitimize credits to these financial debts. A second solution proposed is the Basic Income Guarantee (BIG) or the universal basic income. It consists on regular cash payments to everyone in a community (or country) and has proven a certain efficacy in some places around the world (like Namibia). Another debate addresses the fact that the ecological debt risks “commodifying nature” is exhausting ecosystem services. Researchers have tackled this risk by showing how it will expand the inclination of objectifying, monetizing and ultimately commodifying nature. Moreover, the language of debt, repayments, credits and so forth is understood in Northern countries mostly, and is mostly focused on recognition of wrongdoing but not payment for loss of services for instance.
