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).
Some of that heat is trapped by greenhouse gases in the atmosphere, including carbon dioxide (CO2). Human activity--such as burning fossil fuels--causes more greenhouse gases to build up in the atmosphere. As the atmosphere thickens with more greenhouse gases, more heat is held in.Fossil fuels such as oil, coal and natural gas are high in carbon and, when burned, produce major amounts of carbon dioxide or CO2.cientists have concluded that most of the observed warming is very likely due to the burning of coal, oil, and gas. This conclusion is based on a detailed understanding of the atmospheric greenhouse effect and how human activities have been tweaking it.
