Recent studies show data that earth, for 400,000 years, increasingly warmed up during the start of the Industrial Revolution of the 1850’s. Measurements from the earth’s so-called “time capsules” such as ice cores, tree rings and air show that CO2 concentration in the atmosphere has increased by one-third since 1850. And, scientists also agree that the surface temperature of the earth has risen by one-degree over the last century.
I for one, agree that this phenomenon is truly happening, but what are the solutions to this shocking issue? I agree with New York University Professor of Physics Martin Hoeffert about his view on different technologies that can be substitutes to main energy source, the fossil fuels. Alternatives such as solar, wind, biomass and geothermal energy can be used to lower our use of these fuels. I see that to make these renewables cost-effective, we have to use a lot of land. If we will use biomass energy to sustain our energy needs, we have to fill 10 percent of the Earth’s land. So, that’s where the other renewables kick in.
