A Global food security, defined by the United Nations as the condition in which all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food, is fundamentally interconnected with the planet's climate system. For millennia, agricultural practices have evolved in response to predictable seasonal patterns. However, the accelerating pace of climate change, driven by anthropogenic greenhouse gas emissions, is now disrupting these patterns, posing an unprecedented threat to the stability of our global food supply. The implications are profound, affecting everything from crop physiology to the economic stability of entire nations. B The most immediate and widely understood impact of climate change on agriculture is its effect on crop yields. Staple crops such as rice, wheat, and maize, which form the bedrock of diets worldwide, are particularly sensitive to temperature fluctuations. While a marginal increase in CO2 can sometimes have a 'fertilisation effect', this benefit is quickly negated by the stress from rising temperatures. High heat can impair photosynthesis, disrupt pollination, and reduce the grain-filling period, ultimately leadi…
