World Food Day

October 16th is World Food Day. We feature work on food security under climate change.

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

Our Open Access option complies with funder and institutional requirements.

  • Evidence is growing on the impacts of climate change on human and natural systems. A two-step attribution approach—machine-learning-assisted literature review coupled with grid-cell-level temperature and precipitation—allows comprehensive mapping of the evidence on impacts and tentative attribution to anthropogenic influence.

    • Jan C. Minx
    Article
  • Climate literacy—awareness of climate change and understanding that humans are responsible—is necessary for adaptation and mitigation. Levels of climate literacy across Africa are highly variable, with positive predictors of literacy identified, suggesting areas to target for increasing climate change literacy.

    Article
  • More than 80% of trade by volume occurs via maritime shipping, with growing pressure to reduce associated GHG emissions. The top 10 single-direction trade pairs account for nearly 20% of emissions; optimizing trade patterns could reduce emissions by 38% of current totals.

    • Ke-Bin He
    Article
  • Atmospheric rivers, concentrated plumes of moisture important to extratropical precipitation, have not changed with historical warming. Model simulations suggest that this is due to the competing weakening effect of aerosols and strengthening effect of greenhouse gases, which dominates with future warming.

    • Seung H. Baek
    • Juan M. Lora
    Article
  • Different frameworks, most notably expert assessments from the IPCC, have been developed to determine risk from climate change over this century. Estimated risk scores quantified from the IPCC assessments show a substantial increase in global composite risk by 2100 for low and high emissions.

    Analysis
  • Forests take up carbon from the atmosphere but also change Earth’s surface energy balance through biophysical effects. Accounting for these shows that tropical forests have the highest mitigation potential; the climate benefit of higher-latitude forests is offset by their warming effects in winter.

    • Edouard L. Davin
    • Sonia I. Seneviratne
    Article
  • Small island developing states are currently faced with two significant challenges that are more onerous due to limited financial resources: adapting to increasing climate change risk and recovering from the pandemic. Debt-for-climate swaps provide an avenue for SIDS to address these challenges.

    • Emily Theokritoff
    Comment
  • Nature Climate Change talks to Felipe C. Mandarino, city information coordinator within the Rio de Janeiro city government, Brazil, about building cooperation, facing data and knowledge gaps and responding to climate change in Brazilian cities.

    • Tegan Armarego-Marriott
    Q&A
  • Climate action is needed across the Global South, with just transition the central priority. Nature Climate Change spoke to Maisa Rojas, associate professor at the University of Chile, about Chile’s progress in climate governance and the challenges ahead, as well as the opportunities with COP26.
