Regarding sources that argue about risks on crop yields in the future, I have collected some over time. Apologies for not explaining them more thoroughly - they include reports of past/current crop losses as well as predictable ones, of course caused by many different factors:
Future warming increases probability of globally synchronized maize production shocks (2018)
Amplified Rossby waves enhance risk of concurrent heatwaves in major breadbasket regions (2019)
Climate Change Impacts on Global Food Security (2013)
Plant pathogen infection risk tracks global crop yields under climate change (2021)
World agriculture towards 2030/2050: the 2012 revision (2012, UN FAO) The global groundwater crisis (2014)

But this is all a bit here and there, not an expert who can evaluate the validity of this research
