Carbon Output Must Near Zero To Avert Danger, New Studies Say
The task of cutting greenhouse gas emissions enough to avert a dangerous rise in global temperatures may be far more difficult than previous research suggested, say scientists who have just published studies indicating that it would require the world to cease carbon emissions altogether within a matter of decades.I am a firm believer in global warming/climate change and physics tells us that increased CO2 will contribute to warming. That said I don't believe that we can predict accurately where climate change will lead - there are simply too many variables. What few address is the "real" problem - there are too many people. The estimated population of the earth in 1 AD was 200 million people. In 1800 AD it was approaching one billion, a five fold increase in 1,800 years. Between 1800 and 2000, a span of 200 years population increased six fold to over 6 billion people. This population increase was made possible in large part by fossil fuels. The reality is the earth cannot support six billion hunter-gatherers. The real solution to climate change, peak oil and water shortages can only involve population reduction. Certainly not politically correct so nothing will be done that is significant.
Their findings, published in separate journals over the past few weeks, suggest that both industrialized and developing nations must wean themselves off fossil fuels by as early as mid-century in order to prevent warming that could change precipitation patterns and dry up sources of water worldwide.
Using advanced computer models to factor in deep-sea warming and other aspects of the carbon cycle that naturally creates and removes carbon dioxide (CO2), the scientists, from countries including the United States, Canada and Germany, are delivering a simple message: The world must bring carbon emissions down to near zero to keep temperatures from rising further.
