Green houses

113 CHAPTER 7. THE GREENHOUSE EFFECT We examine in this chapter the role played by atmospheric gases in controlling the temperature of the Earth. The main source of heat to the Earth is solar energy, which is transmitted from the Sun to the Earth by radiation and is converted to heat at the Earth’s surface. To balance this input of solar radiation, the Earth itself emits radiation to space. Some of this terrestrial radiation is trapped by greenhouse gases and radiated back to the Earth, resulting in the warming of the surface known as the greenhouse effect. As we will see, trapping of terrestrial radiation by naturally occurring greenhouse gases is essential for maintaining the Earth’s surface temperature above the freezing point. There is presently much concern that anthropogenic increases in greenhouse gases could be inducing rapid surface warming of the Earth. The naturally occurring greenhouse gases CO2, CH4, and N2O show large increases over the past century due to human activity (Figure 7-1). The increase of CO2 was discussed in chapter 6, and the increases of CH4 and N2O will be discussed in chapters 11 and 10 respectively. Additional greenhouse gases produced by the chemical industry, such as CFC-11, have also accumulated in the atmosphere over the past decades and added to the greenhouse effect (Figure 7-1).

Book page 154 What is the greenhouse effect? | There are two meanings of the term "greenhouse effect". There is a "natural" greenhouse effect that keeps the Earth's climate warm and habitable. There is also the "man-made" greenhouse effect, which is the enhancement of Earth's natural greenhouse effect by the addition of greenhouse gases from the burning of fossil fuels…

Cultivo protegido. 22 ABSTRACT 23 To assess the yield of strawberry cultivars obtained from different types of seedlings, an experiment 24 was conducted at the INCAPER Regional Center Research, Domingos Martins ES, using high 25 tunnel greenhouses with beds covered with translucent polyethylene. Cultivars evaluated were 26 Camarosa, Camino Real and Aromas and three sources of seedlings were evaluated: imported from 27…

: mudanças climáticas; efeito estufa. Abstract Human actions aimed at economic growth without an adequate environmental management have brought serious consequences for the climatic stability of the planet. The greenhouse effect, caused by uncontrolled greenhouse gases emission is a recurring theme in global negotiations relating to the sustainability of life on earth. The objective of the study is to analyze some of the major treaties and major conferences around the world on the…

the Earth's surface. This phenomenon is being observed since the mid-20th century and should continue in the 21st century main cause is pollution and deforestation. Human activities like burning fossil fuels and deforestation are causing the greenhouse effect known. According to scientific projections, the Earth's temperature will increase 6.4 ° C by 2100. Even if there is a stabilization of greenhouse effect, its consequences on the planet can continue for longer. Increasing global…

Como uma devida relevância aborda-se o efeito estufa antrópico , mostrando teorias pós e contra, de que ele seja o causador do aquecimento global.Concluindo-se assim que o efeito estufa é necessário para a existência de vida na Terra, mas que o seu agravamento é prejudicial à mesma. ABSTRACT This article has as objective to define the effect greenhouse, explaining which is its real cause, anduntil point it is benign for the planet Land. Thus, the effect greenhouse in other planet…
