TS.C.3.4 Climate change is projected to increase malnutrition through reduced nutritional quality, access to balanced food and inequality . Increased CO2 concentrations promote crop growth and yield but reduce the density of important nutrients in some crops  with projected increases in undernutrition and micronutrient deficiency, particularly in countries that currently have high levels of nutrient deficiency  and regions with low access to diverse foods .
