Rising temeratures and Rising Risks

It is no secret that the earth's temperature has risen over the past 100 years. The cause is almost certainly the carbon emissions and greenhouse gases that we put into the air everyday of the week. "The world's 17 biggest polluters agreed to work together to limit world temperature increases to no more than two degrees celcius above pre-industrial levels."(Bradford Plumer, New Republic). I have become aware that the earth is currently eight-tenths of a degree celcius above the pre industrial level and with the carbon pollution that we have put up into the air we are most likely locked in for another six-tenths of a degree, which means we only have another six-tenths of a degree left before reaching the the dreaded two degree mark. "Temperature rises above two degrees celcius will be difficult for contemporary societies to cope with, and are likely to cause major societal and environmental disruptions through the rest of the century and beyond."(Bradford Plumer, New Republic). If Global Warming rises to two degrees celcius it would leave the world warmer than it has ever been in millions of years, this seems like a problem considering the earth has been the same temperature since the beginning of human agriculture.
With all of the droughts across the globe including the drought in Australia, and the melting of the polar caps, along with the increase of storm damage like the size and abundance of hurricanes it seems pretty safe to say if the temperature rises past two degrees the problems could and most likely will be catastrophic. "But the long-delayed decision to list the bear as a threatened species may prove less of an impediment to oil and gas industries along the Alaskan coast than many environmentalists had hoped. Mr. Kempthorne also made it clear that it would be "wholly inapropriate" to use the listing as a tool to reduce greenhouse gases, as environmentalists had intended to do."(Felicity Barringer, New York Times).
Many conservatives seem to be willing to now acknowledge the fact that global warming is indeed real, but still feel we should do little or nothing about it. "It might be the case that we could go slightly above two degrees celcius and muddle through. Most conservatives are ready to gamble on this-a habit they've become awfully fond of."(Bradford Plumer, New Republic). It seems to me like pretty much everyone can realize that global warming is taking place, but they are not ready to lose the money and efficiency that can be made from oil and greenhouse gases. When we are talking about the potential lives of many animals and eventually the lives of many humans being lost because of ignorance it doesn't seem right in any way. We are talking about the earth that people have lived on for thousands of years with no altercations, and then to go throw away the beauty and cleanliness for a hundred or two years of burning oil and fuel?
The fate of the earth could very well rest in this generations hands and what we do between now and the next fifty years could decide what will happen to the earth forever.
