Common ingredients include lamb, or mutton (mutton is used as it comes from less tender sheep over a year old, is fattier, and has a stronger flavour, and was generally more common in less-affluent times) as well as potatoes, onions, and parsley.It may sometimes also include carrots.rish stew is the product of a culinary tradition that relied almost exclusively on cooking over an open fire. It seems that Irish stew was recognized as early as about 1800.
The two largest human influences are greenhouse gas (GHG) and sulfur dioxide (SO2) emissions, mostly from burning coal, oil, and natural gas (sulfur emissions tend to have a net cooling effect). The largest natural influences on the global temperature are the 11-year solar cycle, volcanic activity, and the El Nino Southern Oscillation (ENSO).
The Earth has a natural greenhouse effect where certain gases (known as greenhouse gases) in the atmosphere allow the sunlight to enter but absorb the heat radiation.Because these gases absorb the heat, they keep the average surface temperature on Earth around 14Â°C.ince the industrial revolution, human activity has increased the amount of greenhouse gases in the atmosphere (shown in the graph to the right). The increased amount of gases which absorb heat, has directly lead to more heat being retained in the atmosphere and thus an increase in global average surface temperatures.
