Crops at risk from changing climate

Crops at risk from changing climate
May 14th, 2019, by Tim Radford

Global warming could bring yet more challenges to a hungry world. New studies have identified precise ways in which a changing climate puts crops at risk.

LONDON, 14 May, 2019 – Climate change is leaving crops at risk. Driven by global warming – and with it ever greater extremes of heat, drought and rainfall – the rising mercury can explain up to half of all variations in harvest yields worldwide.

Unusually cold nights, ever greater numbers of extremely hot summer days, weeks with no rainfall, or torrents of storm-driven precipitation, account for somewhere between a fifth to 49% of yield losses for maize, rice, spring wheat and soy beans.

And once international scientists had eliminated the effect of temperature averages across the whole growing season, they still found that heatwaves, drought and torrential downfall accounted for 18% to 43% of losses.

Example,the Farm I grew up on in North Western Wisconsin has a increased Growing Season of 10+ days since 1960. And the Rainfall has increased as well. But,the Temperature swings have also increased. When you get 60 degree days in December as well as -10 degrees,baby it is climate change. The damage to Trees and Pasture Lands is happening in real time.

Trees bud too early because of the warm, and then are hit by a "late frost" (which is really just seasonal weather.)

In Northwestern Wisconsin one would experience a weather freak once in a while. But what is happening is something different. As you say,the Fruit Trees have budded in March and not April followed by several inches of snow or Freezing Rain.
