Global Climate Change Impact on Crops Expected Within 10 Years, NASA Study Finds
A NASA study predicts climate change will reduce maize yields by 24% and increase wheat yields by 17% by 2030, highlighting significant impacts on global agriculture and future research directions.

A recent NASA study published in the journal Nature Food indicates that climate change is expected to significantly impact global crop yields, particularly maize and wheat, within the next decade. Under a high greenhouse gas emissions scenario, maize yields could decline by 24% by 2030, while wheat yields may increase by approximately 17%. The study attributes these changes to rising temperatures, altered rainfall patterns, and increased atmospheric carbon dioxide levels. The research utilized advanced climate and agricultural models, including simulations from the Climate Model Intercomparison Project-Phase 6 and the Agricultural Model Intercomparison and Improvement Project, to assess the potential impacts on crop production. The findings suggest that maize, primarily grown in tropical regions, will face greater challenges, while wheat may expand its growing range into previously unsuitable areas. The study emphasizes that even with efforts to mitigate climate change, agriculture will confront a new reality, with potential global repercussions from localized crop yield declines. The research team plans to explore additional factors such as economic incentives and farming adaptations in future studies.
- Climate change is projected to reduce maize yields by 24% by 2030.
- Wheat yields may increase by 17% due to climate change.
- The study used advanced climate and agricultural models for its projections.
- Maize will face growing challenges in tropical regions, while wheat may expand its growing range.
- Future research will consider economic and adaptive factors affecting agricultural yields.

CO2 is making Earth greener–for now Science
A study in Nature Climate Change shows significant greening on 25-50% of Earth's vegetated lands due to increased CO2 levels. This greening, twice the size of the US, benefits plant growth but contributes to climate change. Carbon dioxide explains 70% of the effect, impacting global cycles. Researchers warn of potential acclimatization over time.

A UC Riverside study warns of a northward shift in tropical rains due to unchecked carbon emissions. This shift will affect agriculture and economies near the equator, impacting major crops for about 20 years.
Food as You Know It Is About to Change
The modern food system faces a "food polycrisis" with rising hunger rates, increased food prices, and climate change impacting agricultural productivity. Urgent changes in practices and diets are necessary for future food security.
We haven't seen how bad extreme weather could get
Rapid climate change, driven by fossil fuel emissions, is increasing the frequency of extreme weather events. Past climate data may no longer reflect current conditions, indicating future challenges ahead.
Plan to cut overlooked methane emissions could help stop global warming faster
Researchers from Duke University stress the urgent need to address methane emissions, proposing a three-step plan to reduce them, coordinate efforts with carbon dioxide, and enforce abatement measures for climate benefits.
