The collapse of one of the Earth's most important ocean currents poses a serious threat to global food production. The Atlantic Meridional Overturning Circulation (AMOC), which transports heat from tropical regions to Europe, is severely affected by climate change due to human activities, and scientists warn that this situation could lead to a new ice age in Northern Europe.
Impacts on Global Agriculture
Research indicates that the reduction of this current could lead to decreased grain production in key countries. For example, in the UK and other European countries, wheat, corn, and rice production could drop by up to 19%. This reduction in production could trigger a wave of food price increases, the effects of which will be felt globally.

According to this study, if changes in food production outpace humanity's ability to adapt, food prices could rise by up to 40%. This issue, especially when countries are struggling to maintain their food production, could lead to a global crisis.
Preparing for Climate Changes
Research shows that different countries must prepare for major changes in food production areas. For instance, agriculture may shift to new regions that have suitable weather conditions for growing new crops. However, these changes are not easily achievable and require infrastructure, water, and investment. Additionally, areas that may find better conditions for agriculture may not have the capacity to meet food needs.
Scientists also warn that countries cannot rely solely on their own food supplies. Maintaining international trade in this regard is crucial, as restricting exports during times of reduced harvests could create more severe shortages in other parts of the world.
Research on the reduction of AMOC shows that this current has decreased by about 15% since the mid-20th century and could completely collapse in the future. Scientists estimate that the likelihood of this collapse is nearly 24%, and if this current stops completely, its effects will significantly impact global climate and agriculture.
