Study: Climate change driving spread of crop pests

2013-09-02 11:40:00| Climate Ark Climate Change & Global Warming Newsfeed

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...

Warming helps crop pests spread north, south: study

2013-09-01 08:03:00| Climate Ark Climate Change & Global Warming Newsfeed

Reuters: Crop-damaging pests are moving towards the poles at a rate of more than 25 km (16 miles) a decade, aided by global warming and human transport, posing a potential threat to world food security, a study showed on Sunday. The spread of beetles, moths, bacteria, worms, funghi and other pests in a warming world may be quicker than for many types of wild animals and plants, perhaps because people are accidentally moving them with harvests, it said. Scientists based in Britain studied more than 600 types...

California on edge as wildfires spread

San Francisco Chronicle: What was expected to be a bad fire season is turning out to be just that. Nearly a dozen major fires, some touched off by an unusual string of lightning storms, are burning across California wildlands parched by back-to-back dry winters. Twice as much of the state has burned this year as had gone up in flames at this point in 2012. One of the worst blazes is the Rim Fire, which raged out of control for a fifth day Wednesday in nearly inaccessible terrain west of Yosemite National Park. Hundreds...

Disease may spread faster with rising temperatures

2013-08-18 11:47:00| Climate Ark Climate Change & Global Warming Newsfeed

Wired: Climatologists studying the effects of an increase in global temperatures have said that disease spread may rise in a warmer world. In Science, Sonia Altizer describes work over the last decade that attempts to tease the effects of climate change away from other major factors like poverty. In many cases, the solution is to look to the natural world, which is unencumbered by these factors. Altizer points to students of parasites and pathogens that affect monarch butterflies, reindeer and corals...
