According to a draft report from a U.S. federal advisory committee, agriculture will experience significantly greater strain due to global warming in the coming years. Should global greenhouse gas emissions remain at elevated levels, many parts of the United States will see a big jump in the number of 100-degree days each year, the report says — and this would have dire consequences for agriculture.
By mid-century, the committee believes many regions will experience declines in crop and livestock production due to climate change-induced stresses. They call for increased innovative efforts to ensure the rate of ag adaptation — and the associated socioeconomic system — can keep pace with the changes associated with these stresses. For instance, more frequent precipitation extremes will challenge both rain-fed and irrigated agriculture unless the industry finds a way to implement innovative conservation methods, the committee notes.
