Carbon dioxide global warming, role

Catalytic hydrogenation of carbon dioxide is one of the crucial issues and processes to present a serious option for the global warming control. In particular, methanol synthesis has been considered to play an important role in the transportation of hydrogen energy derived from natural energy such as solar energy, hydropower and so on. 

The seminar on global warming and chemistry s role focused on the current status of energy shortage and reutilization of carbon dioxide. It drove many students to ask the speaker diverse questions related to alleviation of the global warming and energy alternative. 

Because carbon dioxide plays a major role in global warming, many of the proposed solutions to the problem are aimed at reducing the levels of carbon dioxide in the atmosphere. One suggestion is to try altering the chemistry of the earths oceans such that they will absorb more CO2 from the air. 

Scientists agree that energy production, energy distribution, and livestock contribute most to methane emissions, followed by landfill emissions and biomass burning. Thus, even though the concentration of methane in our atmosphere is far less than that of carbon dioxide, its role in global warming cannot be totally discounted, because methane is an efficient absorber of IR radiation. However, the major focus is on carbon dioxide due to the enormous quantities of this gas released into the atmosphere by our carbon-based economy. 

Human activities now play a far more significant role in the carbon cycle than in preindustrial times. The combustion of fossil fuels is replacing stored carbon by carbon dioxide to an even greater extent. We have already seen the possible consequences of this distortion of the carbon cycle an increased level of atmospheric CO2 and a future global warming (page 280). Human disruption of the natural carbon cycle has become a widely debated issue.
