If he was on a 40/60 split his weekly would be $1142.50. If he was on a 60/40 split his weekly would be $1542.50!!! So as you can clearly see, a cosmetologist salary is very relative. And BTW, can be negotiated as your value to the salon increases.
Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.
The atmosphere is made up of many different gases. Several gases have the ability to reflect the sun's energy radiating from the earth back to the earth as heat. The gases with this capability are known as greenhouse gases (GHGs). The main GHGs are water vapor, carbon dioxide, methane, and nitrous oxide. Without some level of GHGs in the atmosphere, the earth would be much colder than it is and life on this planet would be much different.
