Last summer's Central Valley was scorching. Temperatures were substantially above the 30-year normal several days.
Many farmers in the south of the valley had just planted tomatoes when the heat wave came.
Tomato plants aren't sensitive, yet they have limitations, especially when their golden spikes blossom.
Weather affects agriculture often. Climate change makes it tougher to cultivate crops like tomatoes.
Climate warming makes heat waves 150 times more frequent, while other consequences are more subtle.
Climate-exacerbated drought has left crops short on water. Warming winters cause pests and illnesses to invade new tomato regions.
