Crop Pests Spreading North with Global Warming

Scientific American: Crop pests and diseases are moving towards the poles at about the same speed as warmer temperatures. The finding suggests that climate change is driving their relocation, and raises major concerns about food security. Climate change is expected to cause changes in the distributions of species around the world, with an overall shift away from the equator and towards the poles. Ecologists have already documented such a shift in many wild species, including some birds and insects. The changing climate...

Climate change makes pests move north from the tropics

Guardian: Hundreds of crop pests are advancing away from the tropics at a rate of nearly two miles a year, research has shown. The mostly likely explanation for the trend is said to be climate change as rising temperatures make new habitats more inviting. Pest invasions driven by global warming have serious implications for agriculture and food security, according to scientists. Already, between 10% and 16% of global crop production is lost to pests such as fungi, bacteria, viruses, insects and worms. ...
A Warmer World Will Mean More Pests and Pathogens for Crops

Time: When we talk about the challenge of ending hunger and feeding a growing global population, most of the focus is put on increasing production. That`s not surprising -- "more" is our solution to most social problems. But some of the hunger gap could be closed by making better use of the crops we do produce now. Take plant pests and diseases, which have historically laid waste to whole harvests. The Irish potato famine of the 1840s -- caused by the oomycete Phytophthora infestans -- led to the deaths...
Study: Climate change driving spread of crop pests

BusinessGreen: The potential impact of climate change on food production has again been highlighted with the publication of a new study warning that rising temperatures are enabling the spread of crop pests into new latitudes. The paper from scientists at the University of Exeter and the University of Oxford, published in the journal Nature Climate Change this week, calculates that certain crop pests are heading towards the North and South poles at a rate of three kilometres a year, expanding the area where...

Is Climate Change Pushing Pests into Northern Farms?

Mother Jones: In 1996 Colorado received a very unwelcome--and hungry--house guest, the mountain pine beetle, whose voracious appetite for pine has since killed off millions of acres of trees there. A few years later, the beetles came knocking in British Columbia and have now knocked out over half the province's pine timber. The full-bore invasion of these critters, each no bigger than a grain of rice, is now one of the most pressing ecological disasters in the West, and their spread, scientists believe, is driven...
