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).
You can think of greenhouse gases as sort of a blanket for infrared radiation -- they keep the Earth's surface and lower layers of the atmosphere warmer, and the upper layers colder, than if the greenhouse gases were not there. About 80-90% of the Earth's natural greenhouse effect is due to water vapor and clouds.Most of the rest is due to carbon dioxide, methane, and a few other minor gases.bout 80-90% of the Earth's natural greenhouse effect is due to water vapor and clouds.
