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 greenhouse effect is caused by greenhouse gases; the most important greenhouse gases in Earth's atmosphere are: water vapor, carbon dioxide, and methane. When there is more greenhouse gas in the air, the air holds more heat. This is why more greenhouse gases cause global warming.
