The blame for crop failures is Global Cooling....
From Norway...not a big grain producer.....but a "canary in the mine" regarding world wide grain production.....
“The official view in Norway is in contrast to what the people experience because of cooling weather:
Late spring gives flooding and avalanches when late snow-melting in the mountains.
Water pipes freeze because of early and deep frost in the winter.
Insect populations down 40% in 5 years because of cool and wet summers.
This of cause is bad for pollination of fruit and berries.
The grain harvest in Norway this summer is down 18% from average the last 5 years, despite increase in area and better seeds.
But officially it is getting warmer.”
