Global Warming and Farming
People often think of melting glaciers and hurricanes and such when they think of global warming. The truth is, agriculture has been showing the effects of global warming for years now.
There are many studies that show how, in the short run, global warming is not completely bad for farming. As we humans continue to change the environmental factors from the things we do, the immediate effects have actually led to better crops.
With global warming comes an increase in temperatures. This can benefit farmers temporarily. It will create a longer growing season meaning more time for the crops to mature. This is true especially in areas where the fall and spring are typically cool.
The higher temperatures can bring some problems to other areas, though. Global warming will cause more heat in areas that are already warm, often causing the plants to suffer. The earth will be more dry as the rate of evaporation in the soil increases. The droughts that will occur can lead to not only the soil being dry, but also the air, and could lead to some crops burning.
It is also predicted that global warming will bring about changes in precipitation. This change will also affect the moisture in the soil. With global warming often comes the threat of severe weather, so when it does rain, it will tend to come down hard. The hard rain can lead to the soil eroding. This is a factor that would greatly affect farming.
Global warming also brings extra carbon dioxide into the air. This strangely has a fertilizing effect on the crops. This kind of fertilization helps crops such as rice, soybeans, and wheat. This makes carbon dioxide fertilization a global warming byproduct that can be beneficial to farming.
There have always been a lot of obstacles with farming. When you add global warming to the obstacles, it can make it more intense. With global warming, it is more likely that farmers will face hurricanes, heat waves, floods, and droughts for instance. These are problems that are hard for farmers to deal with.
As of now, North American farmers are not in a lot of danger from global warming. In fact, they may be facing some of the positive effects. In the long run, though, if global warming is not stopped, they will be facing much damage.
