  • Agricultural fertilizers are the main global source of ammonia emissions, which harm human health and reduce farmers’ profits. An analysis using big data and machine learning reveals that locally optimized fertilizer-management and tillage practices could slash ammonia emissions from rice, wheat and maize cultivation by up to 38%.

  • The strength of the biological carbon pump was estimated using direct measurements of nutrients collected over decades. The findings indicate that ocean waters can capture and store larger amounts of carbon dioxide than previously estimated. This might have implications for climate-change models.

  • Air-pollution data from pollution-monitoring stations and satellites show that wildfire smoke has influenced trends in levels of fine particulate matter in nearly three-quarters of the contiguous United States, undoing around 25% of air-quality improvements made between 2000 and 2016. Wildfires are likely to further erode air quality in the country as the climate warms.

  • Methane is a potent greenhouse gas. A global data analysis measuring the large quantities of methane released by rivers and streams shows that emissions depend on their connections to the surrounding landscape.

  • Samples from the surface of Jezero Crater on Mars have been analysed by the SHERLOC instrument aboard NASA’s Perseverance rover. Signatures from these samples are consistent with the presence of organic molecules and, together with earlier measurements, could constitute the first in situ detection of organic molecules on another planet.

  • Biodiversity experiments show that a high diversity of plants increases the accumulation of soil carbon and nitrogen, but whether such conclusions hold in natural ecosystems is debated. An analysis of Canada’s National Forest Inventory provides strong evidence that the build-up of soil carbon and nitrogen on a decadal timescale increased with improved tree diversity in natural forest ecosystems.

  • Land-use changes alter the exchange of greenhouse gases, but the magnitudes of these effects remain uncertain. Estimates of net greenhouse-gas emissions associated with different uses of tropical peatland in Indonesia — including intact forest and Acacia tree plantations — could inform science-based practices for managing peatlands as nature-based mitigators of climate change.

  • Changes in salt-marsh areas around the world between 2000 and 2019 were quantified using satellite records, and the effects of these changes — collectively representing a slowing net global loss — on carbon emissions were estimated. Storm events were found to be key drivers of salt-marsh loss in the United States.

  • The world’s largest tropical peatland complex is in the central Congo Basin. A drying of the climate between 5,000 and 2,000 years ago triggered decomposition of peat in the Congo Basin and emission of carbon into the atmosphere. The tipping point at which drought results in carbon release might accelerate future climate change if regional droughts become more common.

  • Roughly half of anthropogenic carbon dioxide emissions remain in the atmosphere, but whether this airborne fraction is changing has been unclear, partly because the emissions from deforestation are uncertain. We used proxy data on deforestation emissions over the past six decades to show that the airborne fraction has decreased.
