  • An operational satellite-based monitoring system using NASA/USGS and ESA imagery enables rapid tracking of global land change, with the area of conversion due to direct human action and fire equaling the size of California in 2023.

  • Markov, Ren, Senkow and colleagues report that in patients with severe SARS-CoV-2 pneumonia, alveolar T cell interferon responses targeting structural SARS-CoV-2 proteins characterized patients who recovered, whereas responses against nonstructural proteins and activation of NF-κB were associated with poor outcomes.

  • Subscriptions to a free, weekly deforestation alert system available on the simple interface Global Forest Watch reduced deforestation in the protected areas and logging concessions of tropical African forests. This suggests that freely available near-real-time forest monitoring systems can help reduce emissions from deforestation if they are integrated with forest policies.

  • High-resolution satellite observations provide an accurate and cost-effective solution to monitoring national and global progress towards Sustainable Development Goals. With a new global cropland dataset, this study reports that during the first two decades of the twenty-first century, the global cropland area increased by 9%, whereas the per-capita cropland area decreased by 10% and the per-capita annual cropland net primary production increased by 3.5%.

  • Deforestation is often driven by land conversion for growing commodity crops. This study finds that, between 2000 and 2019, most soybean expansion in South America was on pastures converted originally for cattle production, especially in the Brazilian Amazon. More soy-driven deforestation occurred in the Brazilian Cerrado.

  • Avoided deforestation is an important part of many climate mitigation strategies, yet monitoring is needed for enforcement. Subscriptions to deforestation alerts lowered the probability of deforestation in Africa by 18%, generating a value of US$149–696 million based on the social cost of carbon.
