EFFECT OF FOSSIL FUELS AND INTRODUCTION OF HYDROGEN ON EARTH'S TEMPERATURE (GREENHOUSE EFFECT, CARBON DIOXIDE).

摘要

The "GREENHOUSE THEORY" says that increase in CO(,2) will warm the Earth. That means certain greenhouse gases (particularly CO(,2)) in the atmosphere allow the Sun's ultraviolet and visible radiation to penetrate and warm the Earth, but then absorb the infrared energy the Earth radiates back into the atmosphere. By blocking the escape of this radiation, these gases effectively form a thermal blanket around the Earth. To rebalance the incoming and outgoing radiation, the Earth's temperature must increase.; A warmer climate could dramatically change existing ecosystems and affect the habitability of many areas of the world. It will raise sea level by warming and expanding the oceans, and by melting ice and snow on land. Change in sea level could flood or cause storm damage to many of the major ports of the world, disrupt transportation networks, alter aquatic ecosystems, and cause major shifts in land development patterns.; A computer model has been developed to calculate the effect of atmospheric CO(,2) concentration and introduction of hydrogen on the Earth's mean temperature. The results were checked with the historical data. After the validity of the model had been established, the computer program was run for the years 1985 through 2100 to estimate the atmospheric CO(,2) concentrations and the Earth's mean temperature.; Atmospheric CO(,2) concentration increases with the increase of fossil fuel consumption. If the fossil fuels are continued to be used as the main energy sources, CO(,2) concentration will reach about 1100 ppm by the end of the next century.; If hydrogen is introduced to replace the fossil fuels, then, depending on the rate of introduction of hydrogen as an energy carrier, the trend will be reversed, and the atmospheric CO(,2), after reaching a peak, will start to decrease.; The Earth's mean temperature increases with the increase in the atmospheric CO(,2) concentration, and therefore with the increase of fossil fuel consumption. If the fossil fuels are continued to be used as the main energy sources, the Earth's mean temperature will increase by about 5.4(DEGREES)C by the end of next century.; If hydrogen is introduced to replace the fossil fuels, then, depending on the rate of introduction of hydrogen as an energy carrier, the trend will be reversed, and the Earth's mean temperature difference, after reaching a peak, will start to decrease. Depending on the hydrogen introduction rate, the Earth's mean temperature increase will be 0.32(DEGREES)C by the end of the next century.
