When scientists look at the past they find that the natural environment has often adapted to climate changes that have occurred over thousands of years. One change that may be the cause of Global Warming is that one will find many plants will be best suited to grow in areas other than where they grow today. Where Ireland is located makes it more apt to cooler conditions because of the Atlantic Ocean currents. There are certain crops that grow better under drier conditions. For example wheat, rice, barley, and vegetables do substantially better than maize, sugar cane, millets and sorghum.
Wheat is an important crop of Irish farmers.
A reduction in yield of wheat is usually due to excessive rainfall rather than ranges in temperature. Also, potatoes grow happily in a wide range of climatic environments. They are very tolerable to a wide range of temperatures. It is not foreseen that potatoes will be adversely affected by Global Warming. If the hypothesis of Global Warming does indeed happen, one thing Ireland should look into is viticulture, especially on the southeastern part of Ireland.
