Global warming is real, but it’s hard to understand what that means for you and I in a real world context.
Try this on: “Pasta is made from wheat, and a large, growing body of scientific studies and real-world observations suggest that wheat will be hit especially hard as temperatures rise and storms and drought intensify in the years ahead.”
Already, a mere 1 degree Fahrenheit of global temperature rise over the past 50 years has caused a 5.5 percent decline in wheat production compared to what would have occurred in the absence of global warming, according to a study published by David Lobell, a professor at Stanford University’s Center on Food Security and the Environment.
By 2050, scientists project, the world’s leading wheat belts—the U.S. and Canadian Midwest, northern China, India, Russia, and Australia—on average will experience, every other year, a hotter summer than the hottest summer now on record. Wheat production in that period could decline between 23 and 27 percent, reports the International Food Policy Research Institute (IFPRI), unless swift action is taken to limit temperature rise and develop crop varieties that can tolerate a hotter world.
Even worse, that means the end of hefeweizens in the summer.
