warming (also called greenhouse effect) describes a gradual increase in temperature is lower than the atmosphere.
greenhouse is made entirely of glass. When sunlight (for short-radiation) and the windows, the greater part, and is heated to the plants, the soil and the air in the greenhouse. Since such articles are heated to provide the heat, but the heat waves are much longer than the wavelength of the incoming solar radiation. This long-radiation can not easily pass through the glass, re-released in the greenhouse, all the heat. the natural greenhouse effectThe term greenhouse effect is used for warming the temperature of certain gases into the atmosphere under normal conditions.
describeSunlight (shortwave radiation) easily through the atmosphere.
After falls and warms the surface of the radiation is long and goes back into the atmosphere. Although some of these long radiation or heat to escape space, mainly absorbed or held in carbon dioxide and other gases which are present in small quantities in the atmosphere. So, these gases form a “blanket” that the country is on average 33 degrees warmer than it would be if this greenhouse effect is not. Without these gases the Earth would be frozen desert, where the average temperature is 16 degrees below zero!How people have changed the greenhouse effect?
human population growth and related industrial expansion, have increased the air pollution and the change in the composition and the atmosphere.
a number of pollutants increase the natural greenhouse effect, resulting in increased global atmospheric temperature.DID YOU KNOW?
* Many countries are reluctant to commit to costly changes that can reduce greenhouse gas emissions, taking into account the uncertainties accurately to global warming.
* atmospheric CO2 concentrations will double the pre-industrial concentration of about 60 years. * above sea level is probably a 60 mm increase for each decade during the next century. * Two-thirds of the population of South Africa are mainly based on coal as an energy source. The provision of electricity to these people as a result the net CO2 emissions resulting from improved overall energy efficiency. What can we doReducing greenhouse gases requires more energy efficiency. Representatives of industry and governments have an important role. But what does the individual do?
-. Reduce electricity consumption-. Use lift clubs, public transport, bicycle or your feet in traffic
– Reduce, reuse, recycle and save energy – the manufacturing of all products requires energy
