The use of electricity accounts for 37% of total LIST. Emissions, while transportation 31%, industry accounts for 15%, residential and commercial 10%, and other non-fossil fuel combustion 6%. That is 99% of the total globe greenhouse gas emissions. Carbon dioxide (CA) emissions in the United States increased by about 7% between 1990 and 2013. (EPA 2015) Not leaving out pollution also a contributor of increases in anthropogenic CA, These things re the cause to the earth heating up, or global warming.
Trees and plants help soak up the CA in the atmosphere but with the tearing down of trees to build industry buildings, residential and commercial buildings there are fewer trees and plants to take in CA for photosynthesis, Hypothesis and Predicted Outcomes If humans could find other resources that do not involve the combustion of fossil fuels, maybe there could be a chance to slow down the increasing CA emissions, if not the globe will continues to heat becoming more and more hazardous to unmans, animals and plants on this planet.
Methods For this lab I utilized information taken from the M. LLC. S. E as well as information gleaned from the Environmental Protection Agency (EPA). The chart below an information gathered for the Results and Outcomes CA concentration trends from 1990 to 2005 Location Code Name of City/Country CA Emissions in 1990 CA Emissions in 2005 SUM Summit, Greenland BREW Barrow, Alaska MOL Manna Lola, Hawaii SMS Titular, American Samoa spot South Pole Antarctica Discussion and Analysis
Looking at the above chart tickets that within the 15 years from 1990 to 2014 there has been a big jump, but thinking about the last 40 years there has been a greater increase. As each generation of new industry products have come on the scene as well as more residential and commercial projects that have been generated, we tend to continue to add to the CA emissions problem. The auto industry is endeavoring on becoming more energy conscious by developing hydro vehicles.
