Abstract

Climate change is one of the major challenges of our time by its negative impact on living organisms and on the environment. Food security could be highly threatened by reducing crop yields and damaging the ecosystems. To ensure the food availability around the world and access of healthier foods, it is necessary to understand climate change impact on plant development and how can it prevented. In this review, we discuss the effects of climate change on plant carbon metabolism. Given that, plants are autotrophs, they use an inorganic source of carbon (CO₂) taken out of the atmosphere to manufacture their own food. Although some studies have shown the increase in growth and yield of some plant species caused by high levels of CO₂ in the atmosphere, there are other variables associated with climate change that could have a negative influence in the plant growth, such as high temperatures and drought.
