Climate change is already threatening our food supply by raising temperatures and causing wildfires, but as a new study in Science suggests, all this heat is speeding up insect metabolism, making them an even bigger threat to human crops and agriculture. If the problem continues to worsen at the projected speed, this could mean serious consequences for global food supplies.
Using a computer model, a team of researchers from various US universities projected global crop yield based on several different warming scenarios. These models, which specifically focused on crop yield in relation to pest destruction, showed that the amount of crops lost globally each year due to bugs will likely increase by 10 to 25 percent per degree of global surface warming.
This is particularly unsettling, as recent projections have estimated that if greenhouse gas emissions continue to increase at the current rate, by the end of the 21st century the Earth will be 3 °F hotter.
