Researchers attribute this to rising temperatures, frequent droughts, and irregular rainfall, making crop predictions difficult and putting farmers at risk of losing the staple crops they have relied on for centuries.
Scientists studied one common climate intervention method, stratospheric aerosol injection, which involves spraying fine particles into the upper atmosphere to reflect some sunlight and slightly lower the Earth's surface temperature. Simulations were conducted for various regions worldwide, from the tropical forests of Latin America to the vineyards of France, for the period between 2036 and 2045, taking into account changes in temperature, humidity, rainfall, and plant disease risks.
The results showed that partial temperature reductions are not enough to stabilize the climate or ensure crop stability, with only a marked improvement in agricultural conditions in six regions, which is not enough to secure food globally.
The researchers stressed that nature's behavior is unpredictable, climate regulation efforts may fail, and the future of coffee, wine, and chocolate crops depends on changing approaches to agriculture and consumption to meet the challenges of climate change.
The research was published in the American journal Environmental Research Letters.
