However, what humans would do from now onwards would make a big difference (Hardy29; John 85). Based on human choices, researchers predict that the earth could eventually warm by as little as two degrees or as much as tend degrees Fahrenheit. According to scientists, the key factor that governments should put into consideration is to stabilize levels of greenhouse gases. The levels concentrations should be around 450 to 550 per million (PPM) or even twice pre-industrial levels. Many scientists believe that this is the point at which much damaging impacts can be prevented. Statistics show that the current concentration levels stand at 380 PPM and this means that there is not much time to waste. Accordingly, efforts should be in place to see a reduction of GHG emissions by fifty to eighty percent in order to be in a safe world by the next century. While governments are working very hard to cut the greenhouse gases, people are also encouraged to participate at an individual level. Two researchers, Pacala and Robert Socolow from Princeton University, suggest one approach called “stabilization wedges” in dealing with the greenhouse gases menace (Romm 124). Their approach is aimed at reducing GHG emissions with the use of technologies that are available in the in the coming few decades, rather depending on a huge change in a single area. These researchers suggest seven wedges that could each reduce emissions. Moreover, all of these seven wedges combined could hold the current emission levels for the next fifty years thus putting the globe on a potential course to stabilize around 500PPM. Global warming.
