Global and Domestic Carbon Dioxide Emissions
& their Effect on Climate Change
Climate effects
The possible effects of global climate change require validation through
the use of a General Circulation Model. With a doubling of CO2 concentration
to 600 ppmv expected global mean temperature may rise between 1.5-9°C
(3-16°F), depending on the climate model and the various positive and
negative feedback mechanisms, precipitation levels may increase 7-15%, and
sea level may climb from between 10 to 100 cm. A 4.5°C (8°F) mean
temperature rise does not suggest a uniform increase of temperature unilatitudinally.
The tropics will cool due to increased cloud formation and the mid latitude
temperature will increase from 6 to 9°C (11 to 16°F) and the polar
region from 9-15°C (16 to 27°F). Accompanying the physical changes
will be meteorological transformations. Tropical storms may double in intensity,
fertile areas may become drought stricken, and a whole host of other climate
based modifications yet to be discovered.
Seidel [7] reports on some of perhaps the beneficial consequences
of the warming commitment. The increase in water vapor and CO2 could stimulate
photosynthesis and plant growth in certain crops and increase precipitation.
The rise in temperature could improve the climate in high altitude areas
and reduce heating costs worldwide. The feature of heating also brings along
its conjugate: cooling or air-conditioning. By the year 2015 the predicted
global average 1°C (2°F) increase will raise air-conditioning loads
10 to 20% [8] requiring new generating facilities.
