Efeito Estufa
Como é gerado
Introdução&nbsp; O efeito estufa tem colaborado com o&nbsp; aumento da temperatura no globo terrestre nas últimas décadas. Pesquisas recentes indicaram que o século XX foi o mais quente dos últimos 500 anos. Pesquisadores do clima afirmam que, num futuro próximo, o aumento da temperatura provocado pelo efeito estufa poderá ocasionar o derretimento das calotas polares e o aumento do nível dos mares. Como conseqüência, muitas cidades litorâneas poderão desaparecer do mapa.

Como é gerado&nbsp; O efeito estufa é gerado pela derrubada de florestas e pela queimada das mesmas, pois são elas que regulam a temperatura, os ventos e o nível de chuvas em diversas regiões. Como as florestas estão diminuindo no mundo, a temperatura terrestre tem aumentado na mesma proporção.&nbsp;
