Could More Efficient Crops Feed a Growing, Warmer World?

Scientific American: In the shadow of a boisterous debate about the safety of growing crops that have been genetically modified, otherwise known as GMOs, the potential of good old-fashioned crossbreeding has been making quite a stir in the agricultural community. A group of researchers recently took a closer look at the genome of sorghum, a drought-tolerant grass crop that feeds half a billion people in Asia and parts of sub-Saharan Africa. Unlike its super-cultivated cousins--corn, rice and soy--sorghum still grows...

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...
Scientists and aid experts plan for a warmer future

Yale Environment 360: Harvard University recently sponsored a conference that brought together two groups -- climate scientists and humanitarian relief workers -- that will undoubtedly be collaborating more closely in the future as natural disasters intensify in a warming world. The woman who was instrumental in opening a dialogue between these two factions was Jennifer Leaning, the director of the FXB Center for Health and Human Rights at the Harvard School of Public Health and associate professor at Harvard Medical...
Warmer temps trigger more disease

Voice of America: Various germs and parasites may find the coming years a time to live longer and prosper. Rising temperatures are changing environments and removing some of their natural impediments. Sonia Altizer is an associate professor at the University of Georgia's Odum School of Ecology and lead author of the study. She said it's a review of research done over the past 10 years to see what trends and new information on climate change have emerged. "One of the big themes that has emerged is that there's...

Map Shows Possible Link Between Warmer Springs and Large Fires in U.S. West

Yale Environment 360: An interactive tool produced by the group Climate Central illustrates how rising temperatures and reduced snowpack in the western U.S. have corresponded with an increase in wildfires in recent decades. Based on federal wildfire data from 1970 to 2012, the graphic shows how large fires in some western states including Arizona, Colorado, and Idaho have doubled or even tripled in four decades, a period when the average spring and summer temperatures in 11 states increased by more than 1.5 degrees...
