Many organisms are accumulating climatic debt as they respond more slowly than expected to rising global temperatures, leading to disequilibrium of species diversity with contemporary climate. The resulting transient dynamics are complex and may cause overoptimistic biodiversity assessments. We propose a simple budget framework to integrate climatic debt with two classes of intervention: (i) climatic credits that pay some of the debt, reducing the overall biological change required to reach a new equilibrium; and (ii) options to adjust the debt repayment rate, either making a system more responsive by increasing the rate or temporarily reducing the rate to buy more time for local adaptation and credit implementation. We illustrate how this budget can be created and highlight limitations and challenges.

许多生物体积累的气候债务是​​因为它们对全球气温上升的反应比预期的要慢，从而导致物种多样性与当代气候之间的不平衡。由此产生的瞬态动力学非常复杂，可能导致生物多样性评估过于乐观。我们提出了一个简单的预算框架，将气候债务与两类干预措施整合在一起：（i）支付部分债务的气候信贷，减少了达到新平衡所需的总体生物变化；（ii）调整债务偿还率的选择，要么通过提高利率来使系统更加敏感，要么暂时降低利率以购买更多时间用于本地适应和信贷实施。我们将说明如何创建此预算，并强调限制和挑战。
