Interesting read from the London School of Hygene and Tropical Medicine.

"If no action is taken to reduce the negative impacts on agricultural yields, the researchers estimate that the environmental changes predicted to occur by mid- to end-century in water availability and ozone concentrations would reduce average yields of vegetables and legumes by 35% and 9% respectively. In hot settings such as Southern Europe and large parts of Africa and South Asia, increased air temperatures would reduce average vegetable yields by an estimated 31%."

Also I note it comments on one of the memes quoted by certain  people  locally about C02 being  'plant food' and elevated levels  increase yields.  "Previous research has shown that raised levels of carbon dioxide would increase crop yields, but this study identified for the first time that these potential yield benefits are likely to be cancelled out in the presence of simultaneous changes in other environmental exposures."  I shouldn't but I   can , so : told you so!

Just in case you were wondering, no we (the world) aren't  reducing our greenhouse gas emissions.  We aren't hitting those Paris agreement targets.  Quite the opposite.   https://e360.yale.edu/digest/co2-levels-break-another-record-exceeding-411-parts-per-million From 2016 to 2017, the global CO2 average increased by 2.3 ppm — the sixth consecutive year-over-year increase greater than 2 ppm, according to Scripps researchers. Prior to 2012, back-to-back increases of 2 ppm or greater had occurred only twice.

For the present our household is awash with our own lettuce, broad beans, peas and strawberries.
