GLOBAL CHALLENGE #4: CLIMATE AND ENERGY OPTIONS<br />

THE ISSUE<br />

As the world’s population continues to grow and as nations develop, the world’s need for food<br />

and energy continues to increase. This means more burning of fossil fuels, the world’s primary source of power<br />

for transportation, manufacturing, utilities, and agricultural production. The combustion of fossil fuels creates<br />

carbon dioxide, which is emitted into the Earth’s atmosphere and becomes a major contributor to the creation<br />

of the greenhouse effect. These gases trap some of the sun’s heat energy and, as they get thicker, increase the<br />

temperature of the Earth’s surface, a phenomenon known as global warming.<br />

Although there are uncertainties associated with the science of global warming, climate change<br />

could affect the larger challenge of sustainable development. The impact of climate change, climate policy<br />

responses, and associated socio-economic development could directly affect the ability of many countries to<br />

achieve sustainable-development goals. Globally, according to the Intergovernmental Panel on Climate Change<br />

(IPCC), it is very likely that the 1990s were the warmest decade and 1998 the warmest year on record. There<br />

is new and stronger evidence that most of the global warming observed in the past 50 years is attributable to<br />

human activities although natural factors may also play a role. 18<br />

The best way to manage the carbon in the atmosphere is to reduce our need for fossil fuels.<br />

Another way is to increase our use of low-carbon and carbon-free fuels and technologies. A third way is to<br />

capture the carbon in the ground and store more carbon in the soil.<br />

Carbon sequestration potential of agricultural lands worldwide (sustained for 50+ years)<br />

is 850-900 million metric tons of carbon per year or 11 percent of the estimated 8 billion metric tons of<br />

carbon per year believed to be contributed by human activity. Sequestration on other lands such as forests,<br />

grasslands, rangelands and biomass crop lands also help. 19<br />

CO2 (PPM) / RADIATIVE FORCING (WM 2 )<br />

The past 100 years have seen a steep climb in<br />

atmospheric concentrations of carbon dioxide<br />

(CO 2). Levels of CO 2 remained steady for about<br />

800 years before that.<br />

While the Earth’s temperature varies over time, a<br />

steady increase in average temperature has been<br />

seen since 1860. The average temperature of the<br />

Earth was higher in the year 1998 than at any<br />

other time in the past 140 years.<br />
