The reality is that something as commonplace as farming is showing symptoms of the results of global temperature rises. Some studies indicate that the news of global warming isn't all bad for farming, at least not in the short run. While humans have changed many environmental elements by their activities, the near term results of these changes frequently lead to better crops. For awhile, it will simply mean more time for crops to grown up due to a longer growing season. This is particularly true for regions where the spring and fall were once quite cool.

On the other hand, these higher temperatures can bring issues in other areas. In regions that are warm, global warming will cause the plants to languish in the heat. Soil evaporation rates will be awfully high, leaving really dry earth.

Add to that, droughts that may make both the soil and the air dry and might even lead to burning of some crops. Global warming is bound to bring about changes in rainfall.

This could lead to changes in the soil moisture. Particularly with the dreadful weather envisioned with global temperature rises, rain will come down hard when it comes. This could lead to more often than usual soil erosion. Unusually enough, all of the additional carbon-dioxide in the air that brings about global warming also has a fertilizing affect on crops. This kind of fertilization is most useful for crops like wheat, soybeans, and rice. When global temperature rises pushes ground level ozone to higher stages, the carbon-dioxide fertilization is voided out by tropospheric ozone. The result's that when the climate changes, the ground ozone levels will rise too. Now, it is even rather more likely a farmer will face droughts, floods, heat waves, and hurricanes, to name a couple.

They'll be harder to conquer than ever seen and they may actually be less rare. The prophecies for the US are neither all bad nor all good. Crops are predicted to gain from the effect of global temperature rises in several regions for awhile. The Great Fields are now more at the mercy of drought, thanks to global warming.

However, Canada will generally benefit from the added heat as farming will take a Northward shift.

At this time, and in the future, global warming does not appear to be a particularly perilous situation for northern US farmers. However, in the future, nothing will be ready to offset the damage which will be due to global warming if it's not stopped.
