Carbon dioxide global wanning

A seminar on global wanning and chemistry s role was given. In the seminar chemistry s role was focused to various solutions for carbon dioxide reduction and energy shortage. 

Callendar, Guy Stewart (1898-1964) English steam engineer and inventor known for propounding the theory that linked rising carbon dioxide concentrations in the atmosphere to global temperature, but he thought this wanning would be beneficial. 

Some people have criticized the idea that fossil-tuel combustion causes global wanning. They say that carbon dioxide is a very small and natural component of the Earth s atmosphere and therefore does not pose a problem. Respond to this faulty argument... 

Figure 21.19 Contribution to global warming by various greenhouse gases. The concentrations of CFCs and methane are much lower than that of carbon dioxide. However, beeause they can absorb IR radiation much mote effectively than CO2, they make a significant contribution to the overall wanning effect.

One of the most important aspects of the biosphere s natural capital is its ability to sequester atmospheric carbon dioxide and convert it to biomass. As discussed in Chapter 8, Section 8.2, and illustrated in Figure 8.2, photosynthesis by plants and algae in the biosphere removes significant amounts of carbon dioxide from the atmosphere, a process that helps to control global wanning.
