Tropical Deforestation and Its Effect on Global Climate

Abstract

Rainforests are the predominant natural vegetation throughout the wet tropics. The defining characteristics of a tropical rainforest are temperature and rainfall. Wherever temperature is high enough and rainfall heavy and regular enough, there is rainforest (Bagheera, 1996). Tropical rainforests of all kinds once covered approximately 14 percent of the Earth’s surface, more than eight million square miles (Conservation International, 1998); forming an equatorial green belt around the Earth rich in diverse plant and animal species. Humans have already destroyed half of this forest area, with most damage occurring in the last 200 years (Bagheera, 1996). In 1987 alone an estimated 20 million acres of Brazilian rainforest were cut and burned (Miller & Tangley, 1991, in Kricher, 1997). At the current rate of deforestation, within 177 years all tropical rainforests on Earth could be gone (Kricher, 1997). The effects of this massive deforestation have already begun to influence the planet. Among the many threats of tropical deforestation, global warming is perhaps one of the most severe. For this reason, a look tropical deforestation and its effects on global climate change will be the focus of this paper.

Introduction

Tropical deforestation refers to the cutting, clearing, and removal of rainforest, usually converting it into other less biodiverse, unsustainable ecosystems. Deforestation is often done for short-term profit at the expense of long-term sound economic and ecological policy (Kricher, 1997). Many factors have attributed to the destruction of rainforests especially over the last two decades. Rainforests are being cut and burned for agric...

Essay about Climate Change Is The Global Warming

- Parties who feel that the Earth is not warming claim that the global average temperatures have not gone up since 1998. The argument follows the idea that the greenhouse effect would not make each year hotter than the previous one since there are numerous processes that impact the global average temperatures and climate, for instance, the internal variability in the climate system, changes in solar forcing, and anthropogenic increase in atmospheric greenhouse gases. There thus follow periods of relatively stable, or even cooler, temperatures....   [tags: Climate change, Global warming, Carbon dioxide]

According to NASA (2010), human actions like burning fossil fuels have caused 75% of the 20th century increase in the CO2 gas; at Aril 2010 CO2 levels were the highest they have been in the past 650,000 years. As far as CO2 absorbs heat, and it’s amount produced by people rises, it can be a causation of global warming. In the article "Global Change Impacts in the United States" (2009) it is stated that human produced CO2 is causing environmental change....   [tags: Global warming, Climate change, Greenhouse gas]

Climate Variability And Climate Change Essay

- Climate change is a change in global or regional climate patterns. Most of the cold extremes of the world is experiencing warming at a more rapid pace than its warming extremes. In fact, the true cold season now exists in only the polar extremes of the African continent. Western Africa and Guinea are found to also face a reduction of precipitation while its neighboring regions, although also affected with reduced rainfall, are more prone to extreme rainfall, indicating the effect of the change global warming has brought (Aguilar, Aziz Barry, Brunet, Ekang, Fernandes, Massoukina, & Zhang, 2009)....   [tags: Climate, Climate change, Africa, Global warming]
