The negative effects of climate change on food security are manifold. Firstly, changes in precipitation patterns and extreme weather events such as droughts and floods can lead to reduced crop yields and livestock productivity, resulting in food scarcity and higher prices. Rising temperatures also affect the growth and development of crops, leading to reduced nutritional value and lower crop quality. Additionally, climate change disrupts ecosystems, impacting pollinators and natural pest control, which further compromises agricultural productivity. Finally, climate-induced changes in sea levels and ocean acidification pose threats to coastal communities, their livelihoods, and access to seafood resources.
1st, global warming does not necessarily translate to less rain. In fact their is every reason to expect more rain, more storms, more summer snow reserves, glaciers get larger.
2nd, if there is more CO2 available in the air, experiments have proven plants utilize more CO2, incorporating more carbon into the plant via photosynthesis, something called “carbon fertilization.” Therefore, plants become larger, more dry matter and increased production (Greater tonnage = more stem, leaf, root and fruit. Plants eat up CO2.
As oceans, lakes, rivers heat up, they can hold less CO2, so more CO2 is available for plant ingestion.
