Climate change is shifting animal distributions. However, the extent to which future global habitats of threatened marine megafauna will overlap existing human threats remains unresolved. Here we use global climate models and habitat suitability estimated from long-term satellite-tracking data of the world’s largest fish, the whale shark, to show that redistributions of present-day habitats are projected to increase the species’ co-occurrence with global shipping. Our model projects core habitat area losses of >50% within some national waters by 2100, with geographic shifts of over 1,000 km (∼12 km yr−1). Greater habitat suitability is predicted in current range-edge areas, increasing the co-occurrence of sharks with large ships. This future increase was ∼15,000 times greater under high emissions compared with a sustainable development scenario. Results demonstrate that climate-induced global species redistributions that increase exposure to direct sources of mortality are possible, emphasizing the need for quantitative climate-threat predictions in conservation assessments of endangered marine megafauna. The authors use long-term satellite tracking to project climate-induced shifts in whale shark distributions and understand their potential future risk of ship-strike. Under high-emission scenarios, the movement of sharks to current range-edge habitat is linked to 15,000-fold increased co-occurrence with ships.

Climate change and inequality are critical and interrelated issues. Despite growing empirical evidence on the distributional implications of climate policies and climate risks, mainstream model-based assessments are often silent on the interplay between climate change and economic inequality. Here we fill this gap through an ensemble of eight large-scale integrated assessment models that belong to different economic paradigms and feature income heterogeneity. We quantify the distributional implications of climate impacts and of the varying compensation schemes of climate policies compatible with the goals of the Paris Agreement. By 2100, climate impacts will increase inequality by 1.4 points of the Gini index on average. Maintaining global mean temperature below 1.5 °C reduces long-term inequality increase by two-thirds but increases it slightly in the short term. However, equal per-capita redistribution can offset the short-term effect, lowering the Gini index by almost two points. We quantify model uncertainty and find robust evidence that well-designed policies can help stabilize climate and promote economic inclusion. Climate change and economic inequality are critical issues, and we still lack understanding of the interaction between them. Multi-model analysis shows how climate policies compatible with the goals of the Paris Agreement, including revenue-redistribution schemes, can reduce inequality—particularly in the short and medium terms.
气候变化和不平等是相互关联的关键问题。尽管有关气候政策和气候风险对分配影响的经验证据越来越多,但基于模型的主流评估往往对气候变化与经济不平等之间的相互作用保持沉默。在这里,我们通过八个大型综合评估模型的组合来填补这一空白,这些模型属于不同的经济范式,并具有收入异质性的特点。我们量化了气候影响和符合《巴黎协定》目标的不同气候政策补偿方案对分配的影响。到 2100 年,气候影响将使不平等程度平均增加 1.4 个基尼指数点。将全球平均气温维持在 1.5 °C 以下可将长期不平等的增加减少三分之二,但短期内会略有增加。然而,同等的人均再分配可以抵消短期影响,使基尼系数降低近两个点。我们对模型的不确定性进行了量化,并发现有力的证据表明,精心设计的政策有助于稳定气候和促进经济包容性。

The dominant paradigm holding that science is always objective needs to be challenged. When scientists’ opinions about climate change and their own fears are seen as irrelevant, it suggests that science is separate from society; however, this perspective ultimately weakens climate science.

Rapid warming in the Arctic threatens to amplify climate change by releasing the region’s vast stocks of soil carbon to the atmosphere. Increased nutrient availability may exacerbate soil carbon losses by stimulating microbial decomposition or offset them by increasing primary productivity. The outcome of these competing feedbacks remains unclear. Here we present results from a long-term nutrient addition experiment in northern Alaska, United States, coupled with a mechanistic isotope-tracing experiment. We found that soil carbon losses observed during the first 20 years of fertilization were caused by microbial priming and were completely reversed in the subsequent 15 years by shrub expansion which promoted an increasingly efficient carbon–nitrogen economy. Incorporating long-term stoichiometric responses in Earth system models will improve predictions of the magnitude, direction and timing of the Arctic carbon–climate feedback. Arctic warming is thought to lead to large losses in soil carbon stocks. Here a 35-year-long fertilization experiment in Alaska shows that increased shrub productivity and changes in plant–microbial feedbacks may eventually reverse trends of carbon loss and restore the soil carbon sink.
