According to a UN report by the Intergovernmental Panel on Climate Change, the effects of climate change are now expected to reach the global food supply: during each decade, our supply is anticipated to decline by 2%, while food prices increase. This comes at a time when food demand is also expected to skyrocket — 14% each decade.
The panel’s 2013 report is far harsher than its previous report, from 2007; the 2013 report includes recent research on how vulnerable crops are to heat waves and droughts, as well as more warnings of the necessity to lower global GHG emissions. However, the panel found that carbon dioxide emissions have the added affect of boosting food production — the gas apparently performs as a type of plant fertilizer.
The panel found that the effects of climate change and global warming will hit tropical regions’ food supplies the worst, due to greater poverty rates and tremendous heat waves. Not being able to satisfy global food demand might force us to cultivate more farm land for production purposes — i.e., deforestation, which would speed up the effects of climate change by releasing significant quantities of carbon dioxide into the atmosphere.
Sweeping climate policy reforms, like the Obama Administration’s, though helpful, come a little late: the report finds that such actions might not be drastic enough to slow down the effects of climate change; advantages from steps, like curbing emissions, will generally be seen late in the 21st century.
