INTRODUCTION With the advent of scientific and technological innovations, humans have achieved enormous industrial and economic successes. However, climate change, characterized by the warming of the earth due to excessive emissions of greenhouse gases, has been recognized as one of the most serious but inevitable consequences of human development. According to Crowley (2000), the combination of a unique level of temperature increase at the end of the 20th century and greater constraints on the role of natural variability provides further evidence that the greenhouse effect has already established itself above level of natural climate variability. system. As a result, people have been affected by gradually unpredictable weather changes in recent times, especially adverse and extreme weather conditions. It would be more useful, however, to pay attention to all organisms on our planet, since climate change has also affected all levels of biodiversity (Parmigiano 2006). As studies have suggested that climate change may become the greatest threat to global biodiversity in the near future (Leadley et al. 2010), predicting the future dynamics of biodiversity under climate change has become a significant task for researchers in this field. Although scientists have built a large amount of models to assess the extent of biodiversity, species loss, etc. in the future, understanding the effects of global climate change on biodiversity and its different levels of response still seems insufficient (Bellard et al. 2012 ). Examining current knowledge of the effects of climate change on biodiversity and the ability to project future impacts using models, Bellard et al. (2012) highlighted the limitations and weaknesses of cu...... middle of paper ......ed in Bellard et al. (2012) seem so natural and intrinsic that it is perfectly reasonable to have variations and uncertainties in model projections of the effects of climate change on biodiversity. Their criticism is significant, but seems somewhat redundant. After all, the improvements proposed in their paper still remain problematic until they can test their effectiveness in the future. I would strongly suggest further studies to validate the improvements proposed in Bellard et al. (2012), and to consider more realistic situations in which researchers can do their best to predict the impacts of climate change on the future of biodiversity.
