Anthropogenic Philippines Crops2004 1495Top (Peng et al., 2004) analyzed weather data at the International Rice Research Institute Farm from 1979 to 2003 to examine temperature trends and the relationship between rice yield and temperature...Grain yield declined by 10% for each 1 C increase in growing-season minimum temperature in the dry season, whereas the effect of maximum temperature on crop yield was insignificant. This report provides a direct evidence of decreased rice yields from increased nighttime temperature associated with global warming.
Warming Global Crops2019 274Top (Ray et al., 2019) statistics were compiled from 1974-2013 for ten crops across ~20,000 political units globally...this is the first observational global study reporting the impact of current climate change on the yields of the top ten global crops...among the top three global cereals, recent yields have decreased for rice (-0.3% or ~-1.6 million tons (MT) annually) and wheat (-0.9% or ~-5.0 MT annually)...we found that crop yields across Europe, Sub-Saharan Africa and Australia had in general decreased because of climate change, though exceptions are present. Similar variations are seen in other crops and regions all over the world...recent climate change has likely reduced overall consumable food calories in these ten crops by ~1%.
