Even if we avoid the business as usual scenario...

From the USDA, which has just been forbidden to use the phrase 'climate change'

I wonder when this will be deleted?

Climate change is very likely to affect global, regional, and local food security by disrupting
food availability, decreasing access to food, and making utilization more difficult. Climate change is projected to result in more frequent disruption of food production in many regions and in increased overall food prices. Climate risks to food security are greatest for poor populations and in
tropical regions. Wealthy populations and temperate regions that are not close to limiting
thresholds for food availability, access, utilization, or stability are less at risk. Some high-latitude
regions may actually experience near-term productivity increases due to high adaptive capacity,
CO2 fertilization, higher temperatures, and precipitation increases. However, damaging outcomes
become increasingly likely in all cases from 2050-2100 under higher emissions scenarios.
