The Problem Due to the world economy’s dependence on carbon based energy sources and a growing population of humans requiring energy from those sources, an exorbitant amount of carbon dioxide is being emitted into the atmosphere. Because of carbon dioxide’s properties as a greenhouse gas, an excess of this gas is a leading factor in the temperature of the atmosphere.

Temperature on the Rise We looked at a new study by a team of climate modelers at the National Center for Atmospheric Research (NCAR). Published in the journal Science. The modeling study quantifies the relative rates of sea level rise and global temperature increase that we are already committed to in the 21 century. Global average surface air temperature to rise by 0.5 degree C and global sea levels to rise another 11 cm (4 in) from thermal expansion alone. http://www.ucar.edu/news/releases/2005/change.shtml

Temperature on the Rise The projected sea level rise is more than twice the 3 inch (5 cm) rise that occurred during the latter half of the 1900s. These numbers do not take into account fresh water from melting ice sheets and glaciers, which could at least double the sea level rise caused by thermal expansion. The new study is the first to quantify future committed climate change using "coupled" global three-dimensional climate models. The worst-case scenario, with greenhouse gases continuing to rise projects an average temperature rise of 3.5°C and sea level rise from thermal expansion of 30 centimeters (12 in.) by 2100.

Management Options 1. Education of women and contraceptive use increase 2. Land Transformation 3. Efficiency Improvements 4. Decrease fossil fuel combustion

1. Education of Women The World Bank performed a study that found that doubling female secondary enrolment in 1975 would have reduced the number of births in 1985 by 29%. Microfinance
