Crop pests moving polewards through global warming

The Korea Herald – Crop-damaging insects, bacteria, fungus and viruses are moving poleward by nearly 3 kilometers each year, helped by global warming, a study said.

A team at Britain’s University of Exeter trawled through two huge databases to chart the latitude and dates for the earliest record of 612 crop pests.

Since 1960, these pests have been heading either northwards or southwards at a rate of around 2.7 kilometers yearly.
