Climate change effects on tropical regions includes changes in marine ecosystems, human livelihoods, biodiversity, degradation of tropical rainforests and effects the environmental stability in these areas. Climate change is characterized by alterations in temperature, precipitation patterns, and extreme weather events.
In the past 50 years, the world's human population has doubled, [20] [12] per capita gross domestic product has quadrupled, [21] and biodiversity has suffered a catastrophic decline. [22] Most notably, tropical forests have been cleared for cattle pastures in South America and for oil-palm plantations in Southeast Asia. [23]
Since the tropical rainforests are the most diverse ecosystems on Earth [217] [218] and about 80% of the world's known biodiversity can be found in tropical rainforests, [219] [220] removal or destruction of significant areas of forest cover has resulted in a degraded [221] environment with reduced biodiversity.
The typical tropical forest may become a carbon source by the 2060s. [46] Researchers have found that, in terms of environmental services, it is better to avoid deforestation than to allow for deforestation to subsequently reforest, as the latter leads to irreversible effects in terms of biodiversity loss and soil degradation. [47]
Boreal forests, also known as taiga, are warming at a faster rate than the global average, [14] leading to drier conditions in the Taiga, which leads to a whole host of subsequent impacts. [15] Climate change has a direct impact on the productivity of the boreal forest, as well as its health and regeneration. [15]
This indicates that tropical forest protected areas are becoming some of the last safe heavens for threatened species. [15] In the 1980s, the United Nations Food and Agriculture Organization conducted a study that concluded that 15.4 million hectares (100 acres) of tropical forest was lost per year. In addition, 5.6 million hectares were logged ...
Originally dry tropical forest, the land is being cleared for soybean cultivation. [5] Biodiversity hotspots are chiefly tropical regions that feature high concentrations of endemic species and, when all hotspots are combined, may contain over half of the world's terrestrial species. [6] These hotspots are suffering from habitat loss and ...
This has a profound ecological impact in that Colombia is extremely rich in biodiversity, with 10% of the world's species, making it the second most biologically diverse country on Earth. [ 151 ] In 2024, deforestation in Colombia's Amazon region has increased by 40% during the first quarter compared to the same period last year, according to a ...
