Impacts of climate change on biodiversity
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 7
Abstract
Considerable biotic changes have occurred globally during these cycles; for the last 11,000 years the Earth has been in a relatively stable warm phase of the cycle and is probably within a degree or two of being the warmest it has been for over 2 million years. At the global level, human activities have caused and will continue a loss in biodiversity. This paper considers the connection between climate and biodiversity. Climate change has synergistic effects with many of the biggest existing impacts to biodiversity. Many studies show that potential climate change impacts on biodiversity through habitat loss and fragmentation, invasive species, Species exploitation and Nutrient enrichment. Distributions tend to shift down temperature gradients. the direction of shifts vary considerably among species depending on which bioclimatic variables are most important in the models for each species (e.g. changes in moisture availability may differ from changes in temperature, and the direction of temperature gradients may alter seasonally), and some species show little or no change.
