<p><span>Tropical forests play a critical role in the global carbon (C) cycle. These ecosystems maintain the highest rates of net primary production (NPP) on Earth (Hengl </span><i>et al</i><span>., </span><span><a id="#nph19511-bib-0014_R_d6461774e632" class="bibLink tab-link" href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0014" data-tab="pane-pcw-references" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0014">2017</a></span><span>), contain </span><i>c</i><span>. 30% of terrestrial C stocks (Jobbagy & Jackson, </span><span><a id="#nph19511-bib-0020_R_d6461774e637" class="bibLink tab-link" href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0020" data-tab="pane-pcw-references" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0020">2000</a></span><span>), and have some of the largest stores of fine-root biomass globally (Jackson </span><i>et al</i><span>., </span><span><a id="#nph19511-bib-0019_R_d6461774e643" class="bibLink tab-link" href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0019" data-tab="pane-pcw-references" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0019">1996</a></span><span>), as well as higher fine-root production and turnover rates compared with other biomes (Cusack </span><i>et al</i><span>., </span><span><a id="#nph19511-bib-0007_R_d6461774e648" class="bibLink tab-link" href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0007" data-tab="pane-pcw-references" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0007">2021</a></span><span>). Tropical forest responses to projected warming, altered rainfall regimes, and elevated CO</span><sub>2</sub><span> concentrations (IPCC, </span><span><a id="#nph19511-bib-0018_R_d6461774e653" class="bibLink tab-link" href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0018" data-tab="pane-pcw-references" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-bib-0018">2021</a></span><span>) are likely to be different from other ecosystems because of their unique characteristics (Box </span><a class="featureLink scrollableLink" title="Link to feature" href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-fea-0001" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-fea-0001">1</a><span>), making targeted research and model development important for understanding tropical forest–climate feedbacks. There is now a critical mass of long-term global change field experiments and modeling efforts in tropical forests, yet thus far there has been little synthesis, cross-site comparison, or multi-site standardized experimentation among tropical forests to help us understand how these biomes are changing. An organized INSPIRE session at the 108</span><sup>th</sup><span> Annual Meeting of the Ecological Society of America set out to tackle just this. Speakers covered large-scale tropical forest field experiments and modeling efforts, with an emphasis on changes in ecosystem biogeochemistry under warming, drying, elevated atmospheric CO</span><sub>2</sub><span>, and changing nutrient status. In this Meeting report, we provide an overview of the large-scale global change experiments presented and highlight the main objectives and opportunities for tropical forest research that emerged, including cross-site comparisons and integration with ecosystem-scale models (Fig. </span><a href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-fig-0001" data-mce-href="https://nph.onlinelibrary.wiley.com/doi/10.1111/nph.19511#nph19511-fig-0001">1</a><span>).</span></p>
