Global warming. Thirdly, there would be less fresh water available. For instance if Quelccaya ice cap in Peru would continue melting in that rate, by 2100 the ice cap would have gone and thousands of people who rely on it for drinking water as well as electricity would be left in jeopardy. Lastly, the high possibility of common droughts and floods would not be evaded.Evidences from researches show that humans are the major contributors of global warming. However, the question of what can be done in order to reduce the causes is still controversial. Politics, economics and even sociology are all significant factors in planning for a future that is less “globe warmed.” Even if countries stopped emitting green house gases from today, the world or rather the earth would still warm by an additional degree Fahrenheit.

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.
