How does climate change affect plants and crops?

Climate change may actually benefit some plants by lengthening growing seasons and increasing carbon dioxide. Yet other effects of a warmer world, such as more pests, droughts, and flooding, will be less benign. Under the HadGEM2 model, corn farmers will see crops decline by nearly 16 percent. …

How does cold climate affect farming?

Frost, and more particularly the freezing and rupturing of a plant cell walls, can damage many crops, particularly early or late in growing seasons. Prolonged cold snaps can also lead to stock losses.

How does climate affect food production?

More frequent and intense heatwaves and extreme weather events are already affecting food prices in Australia. Climate change is increasing the variability of crop yields. … The 2009 heatwave in Victoria decimated fruit crops, with significant production losses of berry and other fruit crops.
