Based on the International Panel on Climate Change’s (IPCC) Special Report on Food Security, climate change is threatening food security. It is threatening food systems (i.e., crops) through warmer temperatures and extreme weather events. Warmer temperatures have triggered an increased spread of pests and diseases, negatively impacting crop production.
Under current greenhouse gas (GHG) emissions, it is estimated that half of all insects will advance their distribution range by 50% by 2100. Insects are commonly classified as pests which can carry disease and infect crops. This means that a greater distribution of insects has potential to threaten 50% more landmass than they currently occupy.
