Kapenta fish production has decreased significantly (R 2 =0.85, P≤0.05) since 1974 at an average rate of 24.19 metric tons per year...both climate (maximum temperature in particular) and nutrients, which are influenced by water levels, are the primary determinants of Lake Kariba's Kapenta production

In this paper, we investigate climatic conditions of the past 30 years (1984-2013) and assess the impacts of the recent climate trends on rice yields in the Mun River Basin in northeast Thailand...Our results indicate that the total yield losses due to past climate trends are rather low, in the range of < 50 kg/ha per decade (3% of actual average yields). In general, increasing trends in minimum and maximum temperatures lead to modest yield losses.

We observe declines in eight out of ten ocean regions, and estimate a global rate of decline of 1% of the global median per year...long-term declining trends are related to increasing sea surface temperatures.

This change in climate had led to emergence of 'new' livestock and crop diseases, crop failure and low yields leading to frequent food shortages, water shortages, poor market access, and variation in pasture availability among other effects.

Historical climate change is responsible for more than one-fifth of the observed increment of CPD occurrence...ranging from 2% to 79% in different provinces.
	Temporal	Global	Crops	2021	7	(He et al., 2021)	https://doi.org/10.1002/joc.7518	We proposed a novel approach to identify and summarize CDHEs [compound drought and heatwave events] by taking "crop growing season" as accumulated period, and investigated the spatiotemporal changes of CDHEs occurring within wheat growing seasons over global wheat-producing areas during 1981-2020...the frequency of CDHEs increased significantly in 28.2% of wheat-producing areas, and the total duration of CDHEs increased significantly in 33.2% of wheat-producing areas

The extreme maximum temperatures and diurnal temperature range indices are environmental factors that negatively impact the rainfed crop production in Nebraska.
	Warming	China	Crops	2022	5	(Tao et al., 2022)	https://doi.org/10.1016/j.agrformet.2022.1088...	During 1981-2018, climate warming shortened growing period (GP) on average by 4.2 and 4.6 days/decade for winter and spring wheat, respectively.
	Warming	United States	Crops	2020		(Eck et al., 2020)	https://doi.org/10.1016/j.agrformet.2020.1080...	In the southeastern United States...detrended county-level yield data (1981-2018) were analyzed...surface crops in the region suffer considerable declines as a result of higher than normal maximum temperatures during the growing season...although drought conditions result in negative departures from expected yield, the findings of this study highlight that excess moisture in the latter part of the growing season (Sep-Oct) can be equally damaging.
	Warming	Hungary	Crops	2017		(Pinke and Lovei, 2017)	https://doi.org/10.1111/gcb.13808	The analysis of 30-year segments indicated a monotonously increasing negative impact of temperature on crop yields.

	Warming	El Salvador	Crops	2024		(Nakamura et al., 2024)	https://doi.org/10.1002/joc.8476	The results show that there has been a significant warming of surface temperatures, an earlier start to the monsoon, a drier and longer mid-summer drought, and a delay in the second peak of precipitation from September to October. These changes have led to an increase in vapour pressure deficit (VPD) in northern Guatemala and along the Pacific coast in winter. High VPD can stress plants and lead to reduced yields.
