Climate research in Latin America and the Caribbean

In a Viewpoint article, nine researchers from across Latin America and the Caribbean discuss their work, the most pressing issues in their regions, and beyond.

Nature Climate Change is a Transformative Journal; authors can publish using the traditional publishing route OR via immediate gold Open Access.

  • Fire impacts soil organic carbon stocks, in addition to aboveground biomass, yet changes are not well constrained. This study shows that more soil carbon is lost from drier ecosystems than humid ones and that the carbon sink is increasing in savannah–grassland regions with declining burned area.

  • Changes in air temperature are usually considered for quantifying changes in temperature extremes such as heatwaves. This study shows that the incidence of heat extremes in soils is increasing faster than air temperature in some regions, with implications for hydrological and biogeochemical processes.

  • The decarbonization of the global iron and steel industry is important for energy systems mitigation. Using a facility-level database, this Article presents cost-effective, region-specific strategies targeting plants with a large age-to-capacity ratio and/or high emissions intensity.

  • Recent decades have seen the increasing frequency of multiyear La Niña events. Here the authors find that there are two different types of multiyear La Niña that are each linked to different mechanisms related to warming in the western equatorial Pacific.

  • The authors estimate the intensity, duration and number of global marine heatwaves from 1993 to 2019, from the surface to 2,000 m. They show generally higher intensity of marine heatwaves at 50–200 m, but increased duration with depth, and predict ocean regions of higher biodiversity exposure.
