Climate change could mean more insect damage for the world’s crops.
Mashable, September 1, 2018: A new study published in the journal Science suggests that as the world warms due to human-caused climate change, more and more bugs will populate the globe.
A team of scientists led by Curtis Deutsche and Joshua Tewskbury examined how insects would affect three of the most important crops: rice, maize, and wheat.
They found that any increase in global temperature could lead to insect-driven losses of 10 to 25 percent, especially in places used to more moderate temperatures. A 2 degree Celsius rise in temperature could lead to 213 million ton loss in the three crops measured.
However, from region to region, the way that heat will affect crops and insects will vary. For example, wheat grows best in cooler temperatures, so if the temperature rises, the wheat will face both a less favorable climate for growth and a higher insect population.
