- Climate change cuts global crop yields, even when farmers adapt
Yields for cassava and sorghum, critical to food security in developing countries, face particularly large declines in the world’s poorest regions The authors also predict an 8% decrease in global crop yields by 2050, highlighting the immediate impacts of climate change
- How will climate change affect crop yields in the future?
As a quick reminder, there are three ways that CO2 emissions and climate change can affect agriculture First, plants can benefit from higher CO2 levels in the atmosphere; this is called “carbon fertilization” Wheat and rice — so-called “C3” crops — can significantly benefit from more CO2
- Climate change impacts on crop yields | Nature Reviews Earth . . .
Climate change challenges efforts to maintain and improve crop production in many regions In this Review, we examine yield responses to warmer temperatures, elevated carbon dioxide and
- Climate poses big threat to crop production, new study says
State of play: The authors analyze over 12,600 regions in 54 countries, looking at six staple crops — corn, soybeans, rice, wheat, cassava and sorghum It's "one of the most comprehensive samples of subnational crop yields ever assembled," the study states It sees future gains in some areas, but declines on a global basis for most crops
- A Food Crisis Is Brewing – Climate Change Could Put Half of . . .
New research reveals that a significant drop in crop diversity due to temperature increases exceeding 1 5°C could have a profound impact on global food security Global warming is already impacting daily life, fueling storms, floods, wildfires, and droughts worldwide
- The Influence of Climate Change on Global Crop Productivity
Over the next few decades, CO 2 trends will likely increase global yields by roughly 1 8% per decade At the same time, warming trends are likely to reduce global yields by roughly 1 5% per decade without effective adaptation, with a plausible range from roughly 0% to 4%
- Study Warns Climate Change Is Already Cutting Global Crop Yields
Higher CO₂ can stimulate photosynthesis, enhance water-use efficiency, and lead to higher yields—at least in theory But in practice, the Stanford study found that those potential benefits have been dwarfed by the negative effects of extreme heat and air dryness
